Latest Patents

One of Takao Kasagi's notable inventions is a **sliding member made of fiber-reinforced metal**. This innovative component is designed for use in compressors that include sliding members, such as portions of vanes, which are in contact with opposite members made of iron base metal. The sliding member is constructed from carbon fiber-reinforced aluminum, which exhibits a coefficient of thermal expansion ranging from 0.9 to 1.6 x 10^-5 per degree Celsius, even in a temperature range of 0 to 250 degrees Celsius. This material composition includes 15 to 40 volume percent of carbon fiber, uniquely distributed within an aluminum matrix without any directional properties.

Another significant patent from Kasagi is the **rotary compressor**. This invention enhances the capacity variation of the compressor by incorporating an unloading port that maintains communication between a working space and a suction chamber, controlled by a valve. By sensing the internal pressure during the compression stroke, and the pressure of the fluid drawn during suction, this system allows for effective opening and closing of the valve. This advanced feature provides suitable hysteresis to the operational characteristics of the on-off valve, ensuring stable performance.
