“ElecTrike” electric three-wheeled vehicle

This three-wheeled electric vehicle achieved stable operation by controlling the two rear wheels independently. By saving weight and controlling the maximum speed and travel range, the vehicle is ideal for delivery to neighborhood locations. Since the vehicle can be charged from a household power supply, it can be used even in areas where it is hard to procure gasoline.

Air-buffer material made with biomass plastic

In order to reduce carbon-dioxide emissions and cut back on the use of petroleum resources, an air-buffer material is made with biomass plastic film produced from plant plastic whose raw ingredient consists of molasses, a residual by-product of the process of extracting edible sugar from sugarcane. This product can even be reused and recycled. Machines for producing the buffer material have also been developed by the company. The fact that users can produce just the amount of air-buffer material that they need on-site thanks to a system for renting machines that eliminates the need to make an initial investment is also an advantage.

Long-Life Power Supply Without Electrolytic Capacitor For LED Lighting

The issue of quality is becoming more important for LED lights. In general, LED light products use an electrolytic capacitor to keep the quality of the power supply when converting an alternating current into direct current. An electrolytic capacitor has a short life as it becomes from high temperature operation. Its operating limit is considered to be around 40,000 hours. This company has developed a high-efficiency power supply without using an electolytic capacitor, in order to realize a long product life cycle which is several times longer than traditional products. As its light does not flicker, it is ideal for reading, studying, and for high-end lighting.
