Title: Cooling method and cooling device for electromagnetic bearing
Inventor: MISHIRO ISAO
IPC: F16C32/04
Filed: 1988-08-19
Abstract: PURPOSE:To interrupt heat conduction to an electromagnetic bearing effectively by providing a groove on the external surface of a rotating shaft or the internal surface of an electromagnetic coil fitted closely to the rotating shaft and flowing cooling fluid through the groove. CONSTITUTION:Cooling fluid enters a circular duct 11 provided on the periphery of a bearing casing 1 through a pipe 12. The fluid passes through a through hole 13 and a splined groove 9, cools a rotating shaft 37, and comes out of a ring 51. Though any cooling means is not provided linearly on a thrust bearing section S, the thrust electromagnetic bearing section S is protected from heat since the heat conducted from a blade 33 and a disk 34 is dissipated by means of the cooling fluid flowing through the splined groove 9 before it reaches the thrust electromagnetic bearing sections S. Thus the groove 9 is provided on the rotating shaft 37 on which the cylindrical core 3 of the electromagnetic bearing is closely fitted to allow the cooling fluid to pass through, heat conduction to the electromagnetic bearing S can be effectively interrupted.

Inventor: INOUE TAKAMASA
IPC: B42D15/10
Filed: 1986-08-30
Abstract: PURPOSE:To improve a security function by accommodating the information enciphered to an optical memory. CONSTITUTION:A memory card 10 includes a CPU circuit 11, which is a processor including a microprocessor, an IC memory 12, and a non-erasing or rewritable optical memory 13. When a cipher key K1 is transferred from a reader/writer 20 to the CPU circuit 11, the CPU circuit 11 generates a cipher key K2 and accommodates this to the IC memory 12. Thus, the CPU circuit 11 completes the preparation of a cipher processing and informs the reader/ writer 20 of it. The reader/writer 20 executes the writing or reading of the optical memory 13 and transfers the data to the CPU circuit 11. The CPU 11 receiving the data decodes the data based on the ciphering key K2 stored temporarily in the IC memory 12, enciphers them and transfers them to the reader/writer 20. The reader/writer 20 outputs the data or writes them into the optical memory 13.
