Title: Space diversity receiver
Inventor: NISHIO TOSHIYUKI
IPC: H04B7/02
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of a diversity effect by moving the installing place of an antenna when a received signal level outputted from an antenna is lower than a prescribed value, so as to obtain the received signal level higher than the prescribed value to avoid a problem that antenna correlation due to the increase of interference between antennas is reduced. SOLUTION: A signal judging device 12 judges whether the received signal level amounts to the prescribed value and when the level is higher than the prescribed value, the device 12 does not output a rotation control signal 12a to a rotation controller 14 but supplies a received signal to a signal processing part. However, when the level is lower than the prescribed value, the device 12 outputs the signal 12a to the controller 14, which rotates a turn table with this signal 12a to move the incoming radio wave receiving position of the antenna 11. Then, when the received signal level becomes higher than the prescribed level, the output of the signal 12a is turned off to stop the rotation of the turn table to fix the receiving position of the antenna.

Title: Switching circuit
Inventor: KINOSHITA TAIZO
IPC: H03K17/60
Filed: 1988-04-20
Abstract: PURPOSE:To execute rise/fall at a high speed by a simple circuit constitution by providing an impedance circuit whose impedance becomes low only when logic of the input potential is switched, in parallel to a load resistance. CONSTITUTION:An impedance circuit 5 is connected in parallel to a load resistance 4 between a power source Vcc and collectors of a pair of differential transistors 1. The impedance circuit 5 operates as a low impedance circuit only in the moment logic of a differential input signal Vin or -Vin is switched, and operates as a high impedance (open terminal) in case of a stationary state of logic of Hi and Low levels. In such a way, it is realized to execute rise/fall at a high speed by reducing a load resistance RL, therefore, an effect of a prescribed high speed is obtained by a simple constitution without using a high speed process high in cost.

Title: Solution treatment for precipitation hardening copper alloy
Inventor: FUJIWARA HIDEMICHI
IPC: C22C9/00
Filed: 1990-04-13
Abstract: PURPOSE:To easily and sufficiently subject a copper alloy to precipitation hardening by means of age hardening treatment by subjecting a precipitation hardening copper alloy containing specific amounts of Fe and P to specific solution treatment and to temporary cooling and further carrying out specific solution treatment and cooling treatment. CONSTITUTION:A precipitation hardening copper alloy which has a composition composed essentially of Cu and containing, as precipitation hardening components, 0.05-5.0%, by weight, Fe and 0.005-0.5% P and further containing, if necessary, 0.1-2.0% Co is heated at 930-1020 deg.C for >=10min, by which Fe, P, and Co are allowed to enter into solid solution in Cu. After this primary solution treatment, this copper alloy is cooled down to the prescribed temp. Subsequently, this copper alloy is heated at 830-900 deg.C for >=5min to allow Fe, P, and Co to enter into solid solution in Cu. Then, the copper alloy after this secondary solution treatment is cooled at >=5 deg.C/min cooling rate. Owing to the above solution treatment, the precipitation of a precipitated phase which does not contribute to precipitation hardening in the course of the final cooling stage can be prevented. By this method, a homogeneous supersaturated solid solution can be obtained and the components contributing to precipitation hardening can sufficiently be precipitated by means of aging treatment, by which the copper alloy can sufficiently be strengthened.

Abstract: PURPOSE:To produce sufficient pressing force from friction board by providing a valve for regulating the pressure in pressure chamber and means for controlling the pressure regulation valve such that the pressure in the pressure chamber will depend on the rotation of input shaft. CONSTITUTION:The pressure in pressure chamber 22 is regulated through balance between the pushing force of pressure fluid against a pressure regulation valve 10 and the pushing force of cam plate 13 against said valve 10 caused through a governor ball 14. Since the clutch piston 20 will press a friction board 21 through clutch facing 27 against the clutch outer 19 on the basis of the pressure in the pressure chamber 22, the input side rotary member 5 and the output side rotary member 6 are brought into such condition as enable of power transmission while brought into such condition as unable of power transmission upon release of said pressure. Since the pressure fluid in the pressure chamber 22 is led through pressure fluid distribution holes 12b and 20a to the sliding section of clutch facing 27, it is protected from burning under semi-clutched condition.
