Angle measuring instrument "Smart LAC Series"

Angle measuring instrument "Smart LAC Series"

High precision and high resolution! Long working distance, non-contact instant angle measurement.

The "Smart LAC Series" is an angle measuring device that measures the tilt of a surface without contact. Conventional displacement sensor methods calculate the height difference between two points, making them less effective for measuring small workpieces. However, this product adopts a laser autocollimator method, allowing measurement at a single point, which enables the measurement of small workpieces. Additionally, it supports single spot measurement and multi-spot measurement. 【Features】 ■ Non-contact instant angle adjustment ■ Long working distance (Measurement range ±0.5 degrees at W.D. 300mm) ■ High precision and high resolution ■ Wavelength selection from red, green, blue, and infrared ■ Capable of measuring the angle of external incident light *For more details, please refer to the PDF document or feel free to contact us.

Corner line strong spring "light small load" 【YEL/DSF】

Corner line strong spring "light small load" 【YEL/DSF】

Compression springs with a load capacity ranging from 6 kgf to 400 kgf made of shaped wire.

The angular wire strong spring "DAIspring" is designed for molds and generates strong force in a small space compared to round wire springs by using silicone chrome steel wire that excels in fatigue resistance and deformation resistance to create deformed wire springs (angular wire springs). Light loads are color-coded with yellow paint. (The paint is also electrophoretic, making it difficult to peel off.)

Corner line strong spring "Die Spring"

Corner line strong spring "Die Spring"

A selection of 2,160 items! Comprehensive catalog of angle line strong springs available as a gift.

Compared to general round wire springs, by using silicone chrome steel wire, which excels in fatigue resistance and deformation resistance, in deformed wire springs (square wire springs), it is possible to generate strong force in a small space. Although designed for molds, they are also used in heavy machinery, elevators, and other mechanical parts. There are standards for light small loads, light loads, medium loads, heavy loads, extra heavy loads, super heavy loads, and high deflection, and they are color-coded by type for easy selection. When choosing DAIspring, please decide on the four points of load, spring outer diameter, number of uses, and deflection to select the appropriate option. *For more details, please refer to the PDF materials or feel free to contact us.

[Case Study] Medical Device Manufacturer for Obstetrics and Gynecology

[Case Study] Medical Device Manufacturer for Obstetrics and Gynecology

Introducing examples of cases where our masking technology met the required specifications.

We would like to introduce a case study of a trial for nylon coating as a surface treatment method for a medical device manufacturer specializing in obstetrics and gynecology. Most of the vaginal speculums currently in use are made of stainless steel, which has the disadvantage of being "cold" as it directly touches the mucous membrane. We proposed a masking technique that allows for assembly and positioning without stress for the patient, and conducted several trial prototypes. As a result, a product that satisfied the manufacturer was completed. [Case Overview] ■ Issue - Most vaginal speculums are made of stainless steel and are cold as they directly touch the mucous membrane. ■ Result - Our masking technology cleared the required specifications. *For more details, please refer to the PDF document or feel free to contact us.

Flexible drain for drainage pipes used in elevated roads and bridge surface paving.

Flexible drain for drainage pipes used in elevated roads and bridge surface paving.

Bridge surface drainage pipes, elevated roads, drainage drains. Essential for rainwater removal and structural preservation. Supporting urban transportation and the environment with sturdy materials and efficient design.

What is a drainage drain? Drainage pipes for bridge pavement, elevated roads, and drainage drains are elements related to the structures of bridges and elevated roads, used to ensure efficient drainage of water and the preservation of the structures. 1. Drainage pipes for bridge pavement: • Role: These are pipes that collect rainwater and surface water generated on the bridge's pavement or road and direct it beneath the bridge. • Design: Typically, drainage pipes are installed beneath the bridge to prevent damage to the structure and flooding. Designs may also consider freeze prevention. • Material: Since drainage pipes require durability, they are commonly made from sturdy materials such as concrete or metal. 2. Elevated roads: • Overview: Elevated roads are constructed without passing through the ground and are typically contrasted with underground passages or tunnels. This minimizes interference with other traffic and ground structures, ensuring efficient traffic flow. • Function: Elevated roads are designed to alleviate traffic congestion, provide flexibility against changes in terrain, and serve as part of an efficient urban transportation system.

Significant cost reduction in preventing red rust and water leaks in apartment water supply piping.

Significant cost reduction in preventing red rust and water leaks in apartment water supply piping.

The red rust prevention device "NMR Pipe Protector" prevents red rust deterioration and leaks in the water supply pipes of apartments, reducing piping renewal costs to 1/5 to 1/10.

The costly part of large-scale repairs in condominiums is the "repair of the water supply piping." By introducing the red rust prevention device 'NMR Pipe Protector' into the water supply piping, it is possible to completely prevent the deterioration of red rust inside the pipes and extend the lifespan of the piping by over 40 years. This eliminates the need for costly piping replacement work during large-scale repairs of the condominium, significantly reducing the costs of such repairs. Additionally, the introduction does not require any water outage work, and it can be implemented at about one-fifth to one-tenth of the cost of updating the condominium's water supply piping, with no maintenance or running costs required afterward. For these reasons, by introducing this product, it is possible to save approximately 80-90% of the costs associated with large-scale repairs of the water supply piping. *For more details, please refer to the PDF document or feel free to contact us.

Sun Coating Nylon Coating

Sun Coating Nylon Coating

Nylon coating is a surface treatment method that involves immersing a component heated to over 200 degrees into nylon powder (in powdered form) to form a coating film.

When the heated component is dipped into the powder tank, the powder melts due to the heat, resulting in a state similar to chocolate bananas sold at stalls. After a few minutes, when the heat cools down, the coating hardens and is complete.
