Patent number: 6121614Abstract: A pyroelectric-type IR receiving element comprises a pyroelectric substrate which is fixed to a supporting body at its support ends and at least one rectangular patch formed in the substrate. The patch is formed on its opposite surfaces with first and second electrodes which are overlapped to each other. The substrate has a U-shaped slit composed of a pair of side slits and a base slit connecting the side slits. The U-shaped slit surrounds continuously three sides of the patch, so that the patch is supported by the substrate in a cantilever fashion at a cantilever end which is opposed to one of the support ends of the substrate. Since a thermal stress applied to the substrate when the substrate is exposed to a temperature change is absorbed by the U-shaped slit, a stress concentration to be considered is not developed in the patch. As a result, it is possible to reduce the occurrence of popcorn noise, while maintaining good IR sensitivity.Type: GrantFiled: April 14, 1997Date of Patent: September 19, 2000Assignees: Matsushita Electricworks, Ltd., Yamaju Ceramics Co., Ltd.Inventors: Ryo Taniguchi, Motoo Ikari, Tomoaki Matsushima, Hiroyuki Yagyu, Yoshihiro Matsumura, Kyosuke Iribe, Toshiyuki Suzuki, Sadayuki Sumi, Kazuhiro Horiuchi, Hideki Ohashi

Patent number: 4804235Abstract: A vehicle air brake system including a deceleration sensing device having a piston cooperating with a lever carrying a magnetic roller for operating a reed switch. Movement of the piston depends upon the magnitude of the air pressure acting on it, and such pressure is proportional to the degree of brake energization. Movement of the piston moves the lever to vary the degree of deceleration required to move the roller for operating the reed switch. Operation of the reed switch operates an electro-magnetic valve to modulate the degree of braking force applied to the front and rear vehicle axles.Type: GrantFiled: February 25, 1987Date of Patent: February 14, 1989Assignee: Nippon Air Brake Co., Ltd.Inventor: Yoshihiro Matsumura
