Title: Radio data communication method
Inventor: KAYAMA HIDETOSHI
IPC: H04B1/40
Filed: 1997-09-22
Abstract: PROBLEM TO BE SOLVED: To provide a radio data communication method with which a radio station that has plural directive antennas does not have to send a control signal in each fixed cycle and can select a self-station antenna in accordance with the opposite communication party in an equally distributed radio network. SOLUTION: A selector of an antenna is switched in a loop of 6-2→6-6→6-7 in an idle state to wait for τ time. When a request signal is received (6-2), a permission signal is sent (6-3) and data is received from the opposite station (6-4) until additional data is finished (605). When sending data is generated (6-6), an ambient station-antenna correspondence table is referred to (6-8) to select and switch to a selector of a sending destination (6-9), the request signal is sent (6-10) and waiting is performed for τ time (6-11). When the permission signal is received from the sending destination (6-12), data is sent (6-13) until additional data is finished (6-14). On the other hand, if the permission signal can not be received, a request signal is immediately sent (6-10) if a sending number is a prescribed number N or less (6-15), and it is sent after random delay is waited (6-16) if it exceeds the number N.

Title: Differential limitting differential gear
Inventor: ISHIKAWA YASUHIKO
IPC: F16H48/38
Filed: 1995-10-04
Abstract: PROBLEM TO BE SOLVED: To increase a transfer ratio without changing the angles of a differential case and the conical surface of a side gear, by arranging a cone ring between the differential case and the side gear to generate friction resistance on three or more sliding surfaces. SOLUTION: Sliding occurs by relative rotations between the inner peripheral surfaces of a first cone rings 18A and 18B and the conical surfaces 12A and 12B of side gears 2A and 2B, between the outer peripheral surfaces of the first cone rings 18A and 18B and the inner peripheral surfaces of second cone rings 15A and 15B, and between the outer peripheral surfaces of the first cone rings 15A and 15B and the conical surfaces 11A and 11B of a differential case 1 respectively. Differential limiting force is generated by this slide friction resistance, and in this case, since sliding occurs among three surfaces, the slide friction resistance can be increased to increase a transfer ratio. In particular, since the sliding surfaces are many, the transfer ratio can be broadly changed by appropriately selecting the material of the cone rings 15A, 15B, 18A, and 18B.

IPC: G11B19/00
Filed: 1990-09-28
Abstract: PURPOSE:To prevent an adverse effect on a readout system from a motor drive by holding the supply of a current to the motor during the readout of data and avoiding the overlap of the readout operation of data with the driving operation of the motor. CONSTITUTION:When a recording medium 15 revolves to a prescribed direction by means of the driving of the motor 17 and reaches a normal revolution, a CPU 12 begins read/write access through a read/write circuit 13.
