Corporate History ／Corporate Information
Our company was originally established to create “unique” products using our “pulse” (digital) circuit technologies, and thus, named “Unipulse.” At the beginning (in 1970’s), we started with communication devices and electronics for measurement and control system. But, those products were simply made to order as per requirements of our customers. Thus, we decided to develop our own products to increase revenue in larger markets, and weighing indicators for load cells were developed to meet demands of industrial scale manufacturers Since then, we have introduced various products to the world as a company founded by an engineer. In 1998, I decided to list the company on the stock exchange to improve our business environment. On the other hand, we could not develop any creative products during the time, and our company stagnated in that sense. During the period, our products earned good reputation, and financial situation was stable. Meanwhile, there were various changes in the environment surrounding our company, and the desire to delist the company from the stock exchange became larger. Therefore, I conducted a management-buy-out (MOB) to end the period spanning over 15 years as a listed company and reorganized the structure of the company at the same time. As a result, new products like torque meters, high stiffness load cells, own strain gauges, grip force meters, multi-axis sensors, UNISERVO (geared servo motor with capability to measure output torque), robots capable of controlling output force, electric balancers , and various kinds of robots were developed one after another. Business related to UNISERVO, Robots and Balancers is expected to be bit different from UNIPULSE.’s business. That is why a subsidiary company “ROBOTEC Inc.” was established to take over the business. This period is the 2nd foundation period for Unipulse, and I will promote the reform to change it better for our customers and employees. Our new subsidiary company, Robotec, also keep introducing latest and innovative technologies to Japan and the world as well. We truly appreciate your support for further growth of UNIPULSE group.
President and Technical General Manager
We manufacture sensors such as loadcells and torque meters using our high-accuracy strain gauges. Our weighing indicators are widely used for auto-weighing machines such as Dosing machines, Filling machines, Packer scale, Hopper scale, Weigh bridges, Belt weighers and so on.
Rotating torque sensor is a newly developed hit-item. It is used to test rotational parts such as motors and engines.
Above mentioned Weighing indicators, Force indicators, Loadcells and Torque meters make up the majority of our sales.
In addition, Unipulse has CMS (Cart management system) business as well.
CMS (Car management system) is a sorting system used for logistics, our technology is leveraged for a cart which has an accurate weight scale.
Our CMS enables speedy and accurate sorting by giving appropriate instructions to operators via wireless LAN.
Direct selling (without depending on trading companies) is our primary sales approach to be a close partner for our customers.
We also cover oversea market with sales office located in key countries, providing repair services and so on.
To supply and develop our new products, “UNISERVO (Geared servo motor with output torque control)” and “MoonLifter (Electric balancer)”, ROBOTEC Inc. was established.
|Strain gauge||An element that converts strain into electrical signal when a load is applied to its housing. It is used as a load detector for UNIPULSE’s Loadcell, Torque meter, Clamp meter and Pressure meter.|
|Rotating torque meter||Our torque sensors are used to detect torque applied to rotating shafts, mainly used for testing motors, engines, and other rotary components. Those are available in wide capacity ranges from 0.05Nm to 10000Nm, and we have drip-proof type as well.
We also offer various instruments for monitoring torques, including (but not limited to) a USB interface for PC connection, digital indicators to monitor torque, rotation speed, and power simultaneously, and a power and energy monitor for motor test benches.
|Load cell||Load cells are sensors used to measure weight or force, available in capacity ranging from 100g (1N) to 100ton (1MN) or even above. Load cells are normally connected to digital indicators for practical use.|
|Weighing measurement||Weighing indicators are used with load cells to configure and control automated weighing systems like batching machines, weight fillers, packer scales, hopper scales, truck scales, constant-feeding belt scale, and so on.|
|Force measurement||Our digital indicators are used with load cells to monitor force applied in assembly operations like press-fitting and riveting for automated quality check (OK/not OK evaluation) of products.|
|Data logger||The following is a list of data loggers that can be used for collecting various data in the field such as temperature, humidity, water level, precise displacement and so on.|
|Amplifiers/Peripherals||Amplifiers for load cells and other strain gauge type sensors, printer, recorders, etc….|
|Displacement measurement||Our displacement sensor product line includes capacitive type with 1nm resolution and non-contact fiber optic type with 3MHz bandwidth. Those are used for ultra-precision positioning, gap measurement, runout measurement, flatness measurement, vibration measurement, and more.|
|Vibration measurement||Our vibration monitors enable measurement of vibration magnitude, real-time analysis of frequency, pass/fail test of vibration level at specified frequency range, and so on.
Piezo type accelerometers or capacitive displacement sensors are used for this application.
|UNISERVO||A geared servo motor with output torque control & Sensing capability. Since UNISERVO is capable of angle and output torque control, it can be used in robotic systems as human friendly actuators. (ROBOTEC’s product)|
|Moon Lifter||Electric Balancer. Moon Lifter allows you to handle heavy components (60kg – 480kg) easily with your hands. It strongly supports the precise assembly of heavy components.(ROBOTEC’s product)|
