Abstract: PURPOSE:To provide the radio communication system in which production of crosstalk in the communication between terminals is remarkably reduced. CONSTITUTION:An area is divided into zones, in which a required relay station 20 is arranged, information during arrangement/non-arrangement by other relay stations is recorded as to each speech channel of a concerned station and when the concerned station allocates a speech channel, the speech channel not allocated by other relay stations is allocated with priority among idle speech channels of the concerned station. When all idle speech channels of the concerned station are allocated by other relay stations, the speech channel in the older order of the allocation start time by the other relay stations is allocated with priority. Or when all the idle speech channels of the concerned station are allocated by other relay stations, the idle speech channel of the concerned station is used to check the presence of a reception carrier and the idle speech channel in which no reception carrier is detected is allocated with priority.

Abstract: PURPOSE:To securely seal the space between a rotating part and a supporting part for a long period of time by providing a throttling means which has been arranged in the midway of the discharge oil passage of a hydraulic pump and whose throttle opening in the oil passage is regulated by a hydraulic pressure, on the rotating part side, and also by introducing the oil passage for supplying operating oil to the throttle means, through the supporting part. CONSTITUTION:In response to the various traveling conditions, supply of operating oil to a throttling means 4 is intermittently carried out via an oil passage 8 provided in a supporting part 7 so as to open or close the means 4 for opening or closing discharge oil passage 30, so that the connecting condition between both right and left wheels can be controlled, and the optimum transmission of driving force corresponding to the pertaining conditions can be carried out. In this case, since the throttling means 4 is provided on the side of a rotating part R, it is not necessary to introduce high- pressure oil discharged from a vane pump 3 (hydraulic pump) to the supporting part 7 for requlating the throttle opening of the oil passage 30. Thus, a high pressure is not applied to the seal for sealing the space between the rotating part R and the supporting part 7.

Abstract: PROBLEM TO BE SOLVED: To prevent an air flow rate measuring apparatus from being corroded or broken and improve the reliability and safety by forming a recess at a module-fixing face and a groove or hole communicating the inside with the outside of the recess. SOLUTION: A mounting fixing face 12 for fixing a base member 13 of a circuit module 10 is formed schematically in the same outside shape as the base member 13. A recess 19 is formed inside the face 12. A plurality of grooves 18 are formed nearly symmetrically to the vicinity of the center of an insertion hole 11 of a wall-like part 16 surrounding the periphery of the insertion hole 11. The recess 19 prevents the member 13 from interfering with the fixing face 12 even if a projection or the like is present at a bottom face of the member 13 or the bottom face is not flat. Even when water enters a gap between the member 13 and fixing face 12 or a body 1 is mounted in an inclined state to a horizontal plane, the water is discharged through the grooves 18 and not left in the recess 19. The corrosion/deterioration of peripheral members such as the member 13, body 1, etc., is lessened.

Title: Power supply apparatus
Inventor: MURATA SHINJI
IPC: H01J23/34
Filed: 1996-02-22
Abstract: PROBLEM TO BE SOLVED: To transform the waveform of high voltage pulses into the flat pulse waveform without enlarging the apparatus by draining the electric charge to a load from a sag compensating means so that the load current detected by a detecting means agrees with a specified value, and compensating the generation of a sag voltage. SOLUTION: When, the load current detected by a current detector 26 is converted into the voltage signal by a reference power supply 28, an error amplifier 29 subtracts the voltage signal from the reference voltage outputted from a reference power supply 28 and outputs the error signal. When the error signal is inputted into a driving circuit 30 from the error amplifier 29, the FET of a sag compensating circuit 31 undergoes on/off control so that the error signal becomes the zero value, and the generation of the sag voltage is compensated. Therefore, the waveform of high voltage pulses can be transformed into the flat pulse waveform without increasing the capacitance of a discharging capacitor 24, that is to say, without enlarging the apparatus.
