Title: Allocation system for mobile subscriber call channel
Inventor: FUKUI TAKESHI
IPC: H04W76/00
Filed: 1992-01-28
Abstract: PURPOSE:To secure a call channel group without being affected by radio environment by separating the call channel group for more than necessary channel separation which is to separate the transmission call channels of a base station into respective wave bands and to decide a distance between the wave bands by means of the performance of a transmission sharing unit. CONSTITUTION:The call channel groups 2 allocated to the respective base stations are separated by a value 5 more than necessary call channel separation which is to decide the call channel 1 allocated to the mobile station by the performance of the transmission sharing unit in the base station. The call channel is preferentially allocated to the specified base station by a method allowing the allocation of one wave per base station in the same wave band, and of plural waves per base station in the same group band under restricted radio environment. The respective base stations allocate the channel among the allocated call channel groups 2. Since the adjacent wave bands are separated at that time, the call channel group can be secured without interference and without being affected by radio environment even if the channel is dynamically allocated.

Filed: 1992-02-26
Abstract: PURPOSE:To improve sealing property against thermal load in an actuator which controls a valve, where inside or outside is exposed to a high temperature, in relation to air pressure, by forming all the component parts thereof of a metallic material. CONSTITUTION:In a gas supply system for semi-conductor industry, an organometal with high boiling point is gasified for use.

Title: Power failure detection signal apparatus of dc stabilized power supply
Inventor: KOBAYASHI TOSHIO
IPC: G01R19/165
Filed: 1989-02-21
Abstract: PURPOSE:To obtain a small-sized lightweight inexpensive DC stabilized power supply without using a commercial transformer by providing a circuit discriminating the component voltage taken out by a commercial frequency component detection filter and judging power failure to output a signal. CONSTITUTION:When a commercial power supply 1 is subjected to DC conversion by a rectifier 2, a VA-waveform containing a commercial ripple voltage component is generated in a primary conversion condenser 3 and, when said waveform is subjected to high frequency switching by a transistor 4, the voltage generated in the secondary winding 8 of a high frequency transformer 5 also contains a commercial component and, when the waveform is rectified by a diode 9, a high frequency voltage envelope becomes a commercial ripple component like a VB-waveform and only the commercial component is taken out by a filter 10 to be compared with a threshold value VREF and the presence of a point exceeding a commercial frequency one-cycle time T is discriminated at every cycle. When voltage 1 is cut off, voltage exceeding the threshold value VREF is not generated and power failure is judged on the basis of the absence of voltage within the time T to output a detection signal VS. By this method, a small- sized lightweight inexpensive DC stabilized power supply can be obtained without using a commercial transformer.
