A new ADCP equipped with a scientific fish finder sensor (frequency 70~120 kHz)! It can measure both flow and biomass with a single device.

The Signature100 is a completely new ADCP equipped with both a flow direction and velocity profiler (with a measurement range of 400m) and a scientific fish finder sensor (echo sounder). For example, when focusing on the relationship between the behavior of fish and microorganisms (such as krill) in the ecosystem and ocean currents, it was previously necessary to measure acoustic reflections (echograms) and flow direction and velocity data with separate devices. The Signature100 allows for the acquisition of both types of data with just one device. Specifications of the scientific fish finder sensor: Beam width: 15° (70 kHz), 8.7° (120 kHz) Monochromatic pulse: 70kHz, 90kHz, 120kHz Frequency chirping: center frequency 100kHz (BW50%, 70kHz–120kHz) Vertical data spatial resolution: 0.375–4m (1800 data points) Pulse length: 0.5–6ms Resolution: 0.01dB Dynamic range: 130dB

In addition to conventional multi-layer flow direction and velocity measurement, it is equipped with various measurement options. It can accommodate various observation purposes such as waves, turbulence, sea ice, and echograms, all in one device.

The Signature1000 and Signature500 are lightweight, compact, and multifunctional acoustic Doppler current profilers (ADCP) designed to meet various measurement needs in coastal areas. Functions such as wave, turbulence, sea ice, and echogram measurements can be freely selected and added later. Echograms can be obtained by using a transducer positioned at the fifth center as an echo sounder, allowing for high-resolution measurement of underwater biomass. With the new AD2CP platform, it is now possible to simultaneously execute multiple measurement functions (patented technology), enabling the acquisition of high-density information in a short period. They are also optimal tools for turbulence observation. Regarding sampling frequency, the Signature1000 has a maximum of 16 Hz, while the Signature500 has a maximum of 8 Hz. It has become possible to analyze parts of the turbulence spectrum that were previously difficult to measure.

A lightweight, compact, and simple-shaped ultrasonic flow direction and velocity profiler. It also features pressure wave measurement (PUV) capabilities, catering to various measurement applications.

The Aquadopp Profiler is a highly versatile ultrasonic Doppler current profiler (ADCP). There are four types in the lineup depending on the measurement range (distance). It is the ideal ADCP for those who want to simply conduct multi-layer current and velocity observations. In particular, it allows for wave measurements using a pressure gauge to be performed between current and velocity measurements, making it a series with high cost performance. The model equipped with the Z-Cell function can emit sound waves horizontally from the sensor head, allowing for the measurement of flow around the instrument. This feature enables the measurement of flow very close to the instrument, which was difficult with conventional ADCPs. The measurement range is from less than 1 m to over 85 m. The measurement range is determined by the acoustic frequency of each model. (Model name: Maximum measurement range) - Aquadopp Profiler 2MHz: 20m - Aquadopp Profiler 1MHz: 25m (including Z-Cell) - Aquadopp Profiler 600kHz: 40m (including Z-Cell) - Aquadopp Profiler 400kHz: 90m

We have streamlined the complex mechanisms involved in handling flow velocity sensors and revamped the design and functionality to enable measurements with as few steps as possible. For the first time at Nortek, data quality verification and processing will be performed in the cloud (eliminating the need for dedicated analysis software). Japanese language support is available. [Easy Operation] Automatically sets three water depths and continues measurements while tracking water level changes. Users do not need to specify the measurement depths. [No Cables Required] Non-contact communication (for Eco and disconnection device settings) *Uses the built-in Bluetooth communication function of a smartphone or PC. [No Battery Replacement Needed] Uses a built-in rechargeable battery with non-contact charging. [Simple Setup] Settings can be configured via a web page on the internet or a smartphone app (iPhone and Android compatible apps are available: Nortek Eco; the web page can be accessed via "Related Links"). [Features, etc.] - Low water depth compatibility: Measurements can be taken from 30 cm above the device. - Number of measurement points (water depth, layers): 3 - Equipped with GNSS - Multi-color LED for operation confirmation *Installation is only upward. *Output data will be the horizontal flow velocity (east, west, south, north) at three water depths, but the measurements are three-dimensional flow velocities.

When buying new cosmetics, while the bottle design is important, what catches the eye first is definitely the "box." When faced with a selection of many cosmetics and unsure of which to choose, it often comes down to making a "package purchase," similar to impulse buying based on the cover. This time, we asked our long-time partner, the cosmetics manufacturer Kurecos Co., Ltd., why they continue to create packages with Kaypack. 【I can hardly remember when we started working with Kaypack】 We began our dealings with Mr. Kita (Kaypack) over 20 years ago, so long ago that I can hardly remember the beginning. In the early days, we relied on another packaging company. However, since starting our relationship with Mr. Kita (Kaypack), we have entrusted the majority of our packaging production to them. There is a mutual understanding developed over our long relationship, and the sense of security that comes from knowing they understand everything makes it easy to request work from them. There is a level of stability that allows us to build trust.

The "Hybrid Joint TCF Type" is a bridge expansion device designed for the Tohoku region that responds to "compacted snow," which occurs due to vehicle traffic after snowfall. It meets the 10kN snow load standard set by the Tohoku Regional Development Bureau. Additionally, it adopts a structure known as the "face plate type," which ensures that the water-stopping material does not become exposed on the surface, and it comes standard with "secondary water-stopping material." By employing a double structure, it reduces the risk of leakage and achieves higher water-stopping performance. Furthermore, to prevent snowplow blades from getting caught on the expansion device, it also comes standard with a "snow removal guide plate." This not only protects the product itself but also considers safety during snow removal operations.

Castem Co., Ltd. and Castem Global Group's Castem Vietnam held a completion ceremony for the newly established Vietnam factory in Quang Ninh Province, Northern Vietnam, in January 2026. This is the first time our group has expanded into Vietnam, and this factory will be our seventh overseas production base. After the planned second phase of construction, it is expected to become the largest production base in the group in the future. The factory will manufacture lost-wax precision casting parts used in semiconductors, precision machinery, and construction machinery. We chose Vietnam, where economic growth is anticipated, as a new production base for our main business of lost-wax precision casting. Currently, we are advancing prototype production and plan to start mass production by the end of May 2026. Once the second phase of construction is completed by the end of 2028, we will ultimately be able to produce one million units per month (with a product shipment weight of approximately 120 tons per month). On the day of the ceremony, about 100 participants, including business operators and local stakeholders, attended and toured the various processes such as mold making, casting, and processing. Although we are starting with a compact system in terms of equipment and personnel, we will continue to take on challenges and advance our business to a new dimension.
