Abstract: PURPOSE:To integrate a device highly and reduce its size and weight, and to improve the utilization efficiency of a radio wave by using a single fixed oscilator as a common oscillation source for both transmission and reception and performing simultaneous transmitting and receiving operation. CONSTITUTION:A fixed oscillator and heterodyne detector 1, a low-pass filter 2, a rectifying circuit 4, a switching circuit 5, a low frequency oscillator 6, a driving oscillator 7, buzzer Bz, a light emitting element D2, etc., are provided. Then, a carrier from the fixed oscillator of the detector 1 is transmitted from an antenna through an oscilator and high frequency transformer, a carrier from the opposite device arrives from the antenna at the same time and is inputted to the detector 1 to perform heterodyne detection. Then, a low frequency signal based upon the carrier frequency and the reference frequency of the fixed oscillator is extracted and a high frequency component and a nearby disturbing wave are removed by the filter 2; and the signal is made into DC by the circuit 4 and level-converted by the circuit 5. Further, the output of the oscillator 7 is intermitted through the oscillator 6 and then while the buzzer B2 is put in sounding operation intermittently, the element D1 is allowed to flash intermittently, so that the approach of the opposite body into a specific distance range is known.

Abstract: PROBLEM TO BE SOLVED: To facilitate control of the working fluid containing capacity by injecting a working fluid into a heat pipe container having a plurality of openings, heating a partial region including the working fluid containing region while cooling a region remote from the opening, and then sealing the openings. SOLUTION: Specified quantity of working liquid 40 degassed previously by heating up to 100 deg.C is injected through the opening 11 of a heat pipe container 10. The container 10 is then set at a heating block 20 and a cooling block 30 while directing the opening 11 upward. When heating/cooling of the container 10 is started, steam 41 of working fluid 40 blows off from the opening 11 along with water in liquid phase and settles after a while. When the opening 11 is sealed under that state, a heat pipe containing appropriately controlled quantity of working fluid 40 is obtained. According to the structure, excess boiling of working fluid is retarded and the quantity of working fluid being left in the heat pipe container can be stabilized easily.

Abstract: PURPOSE:To attain initial locking in the reception timing at a high speed by sending a synchronizing signal comprising a frequency component being 1/4 speed of a modulation speed as a synchronizing signal from a transmission section and extracting reception timing component from a signal by a reception section. CONSTITUTION:A transmission data sent from a terminal 1 is subject to orthogonal amplitude modulation by a modulation section 2 from a transmission section 10 and the result is outputted from a terminal 3 as a transmission signal. The reception signal given from a terminal 4 is demodulated by a demodulation section 5, reproduced as a reception data via a proper waveform equalization and the result is outputted from a terminal 6.

If the opening/closing valve 52 is closed and the ones 5, 51 are opened while the water reserve tank 1 is kept full, service water will merely pass through the tank 1, and water in this tank 1 make circulation at all times. In the event of fire, a water feed pipe of a pump vehicle is coupled with a fire hose coupling part, and now the water in the tank 1 is sucked by the pump vehicle, and besides the water fed from the service water mains is serviceable. This allows use of a great quantity of extinguishing water in the initial period of fire extinction process.

Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To provide a developing device which maintains the toner supply ability and toner scraping ability of a toner supply roller by providing a pressure maintenance member by which a developer carrier and the developer supply member are in contact with each other while constant pressure between them is maintained. SOLUTION: An expansion spring 19 as the pressure maintenance means is set between the shaft of the supply roller 14 being the developer supply member and the shaft of the developer roller 15 being the developer carrier. Guide members 20 are fixed in a toner tank 13 and above and below the shaft of the supply roller 14 so as to be parallel with a straight line connecting the shafts of both the rollers, therefore the supply roller 14 can move parallel to the guide members 20. Even in case the supply roller 14 clogs with toner 33 and its hardness changes, the supply roller 14 moves maintaining pressure between the developing roller 15 and itself. Thus, a change in the ability of the supply roller 14, for example, to supply toner to the developing roller 15, which is caused by a change in the pressure between both the rollers, can be prevented.
