Title: Space-feed phased array antenna device
Inventor: TOKAJI ISAO
IPC: H01Q3/24
Filed: 2000-07-11
Abstract: PROBLEM TO BE SOLVED: To reduce a transmission blind region by a simple constitution. SOLUTION: In a reflector 112 by an array antenna, a reflection-type phase shifter is connected to every antenna element, a space feed is executed from a primary radiator 111 toward the arrangement face of the antenna element in a transmission, a transmission signal is sent out, and a reception signal which is sent out from every antenna element is fetched by the primary radiator 111 in a reception. A transmitting antenna 113 is arranged on a face on the opposite side of the signal sending-out face of the primary radiator 111, and the transmission signal can be sent out to a direction opposite to the primary radiator 111. Since radio waves radiated from the transmitting antenna 113 hardly creep to a reception system, the transmission blind region can be reduced.  When a target is brought close, the radio waves are transmitted by using the transmitting antenna 113 by a selector switch 116, and the radio waves which are captured by the array antenna are switched in such a way that they are collected by the primary radiator 111 so as to be received.

Title: Connector
Inventor: NAKAMURA HIDETO
IPC: H01R13/627
Filed: 2000-07-12
Abstract: PROBLEM TO BE SOLVED: To reduce height. SOLUTION: Since a receiving plate 16 (fitting direction tip side end part) of an energizing means 20, pressed by a pressing part 44 in a fitting process, repels the pressing part 44 by energization of a compression coil spring 25, when fitting work is finished with both housings 10 and 40 in an insufficiently fit state, the incompletely fit state can be determined by this. Since the energizing means 20 (the compression coil spring 25 and a slider 21) and a lock arm 12 are arranged in a line along an upper face 10S of the first housing 10, height of the first housing 10 can be reduced, and in turn, to reduce height of the whole connector.

Title: Ring laser, method of driving the same, gyro apparatus, gyro apparatus driving method and signal detecting method
Inventor: NUMAI TAKAAKI
IPC: G01C19/66
Filed: 2000-07-12
Abstract: PROBLEM TO BE SOLVED: To accurately and stably detect the rotating direction and the rotating velocity without using a mechanism such as dithers, by limiting the number of oscillation modes without causing a ring laser type gyro to lock in. SOLUTION: An inside route (circumferential length d3) and an outside route (circumferential length d4>d3) are connected at points A, B. Such a combined resonator suppresses sub-modes enough to result in a single longitudinal mode. The inside and outside routes are optical coupled to keep a laser beam from reversing its cyclic travelling direction during propagating in the combined resonator. As the result a travelling wave never combines with a backward wave due to coupling of the routes. Thus, a single longitudinal mode can be realized without causing the lock-in.

Title: Control device for vehicle transmission
Inventor: NAKAO MICHIAKI
IPC: F16D48/02
Filed: 2000-07-31
Abstract: PROBLEM TO BE SOLVED: To provide a control device for a vehicle transmission to control an automatic clutch so that the temperature of lubrication oil in the transmission is rapidly increased. SOLUTION: In the case that viscosity of lubrication oil in the transmission 16 is high when a shift lever 170 is operated to a non-running position, since the automatic clutch 14 is controlled to the engagement side, rotation of an engine 12 is transmitted to an input shaft 42 of the transmission 16 and lubrication oil in the transmission 16 is agitated. Thereby, when a vehicle is run especially in cold environment, lubrication oil in the transmission 16 is comparatively rapidly increased in temperature. Thus, since a period in which viscosity of lubrication oil in the transmission 16 is high is shortened, a period in which the occurring period of comparatively high dragging resistance (torque) and a period in which a speed change feeling is lowered are shortened, and a shift load is relieved and durability of a synchronizing device is improved.
