摘要： PURPOSE:To realize the miniaturization and the reduction of power consumption for a terminal device of a car telephone system, by carrying out the synchronization and th reproduction through the same circuit for both the data clock signal for circuit connection control and the circuit monitor tone signal in the busy mode. CONSTITUTION:The signal given from a signal receiver is applied to a terminal IN. The switch control is given the differentiating means of a phase information extractor 3, the counting conditions of an up-down counter 5 and a counter 6 plus a changeover switch 2 respectively according to the state of a circuit mode line 9 (set at 1 and 0 in he circuit connection control mode and the busy mode, respectively). When the burst data signal for channel switching in the busy mode is received, the initial specific pattern is detected by a detector 8. Then the circuit mode signal is switched for the reception of data just for a prescribed period.

摘要： PROBLEM TO BE SOLVED: To input information characteristic to a facility layout and production facilities such as flow lines and automatically judge hazards which may be caused in production processes, in an analysis based on HACCP(hazard analysis and crucial control point method). SOLUTION: Inputted food production process flow data, facility layout data, and data corresponding to processes and facilities are stored in a device 108 for storing the information of the processes and the facilities by the use of a device 103 for editing the information of the processes and the facilities. The inputted data of hazards which may be caused in targeted production processes and the inputted data of influence areas on the facility layout are stored in a hazard information storage device 109 by the use of a hazard-editing device 104. A hazard analysis device 105 judges facilities in the influence area of each hazard stored in the hazard information storage device 109 on the facility layout, judges facilities used in the production process among the above judged facilities, further judges the name of the process used for the facilities, and outputs the process name and hazards which may be caused in the process.

摘要： PROBLEM TO BE SOLVED: To lessen the pressure difference between a closed space and the outside air pressure and miniaturize the device as a whole, by absorbing the pressure change of the closed space and keeping it in a certain fine positive pressure, owing to the volumetric chance caused by the movement of the airtight container connected to the closed space, necessitating the protection against the pressure change in the space. SOLUTION: A pressure control system to examine the circulation of substances by plants is constituted of a plurality of rubber buffers 200 absorbing the ordinary outside air pressure change and the pressure change of a plant- cultivation section 100 constituted of a closed space completely cut off from the outside air, by the volumetric change of the movement thereof and a pipe 110 connecting the plant-cultivation section 100 and the rubber buffers 200. The rubber buffer 200 made of chloroprene rubber in which nylon fibers are woven to have flexible and light-weight characteristics absorbs the pressure change of the plant-cultivation section 100 by increasing or dectreasing the volume in a fine pressure difference between the presure in the section and the outside air pressure and keeps the section in a fine positive pressure and prevents the penetration of the outside air.

摘要： PURPOSE:To continuously generate power in a generating system for converting solar light energy to electricity even if it cannot temporarily receive solar light. CONSTITUTION:A generating unit comprises a thermoelectric conversion module 1 which can generate power even if the direction of a heat flow is reversed and does not have a dynamic constituent, and a heat accumulator 2 connected directly to the module 1. Thus, even if a solar light is not emitted directly or indirectly to a light receiving surface of the module 1, heat is continuously supplied from the accumulator 2 to the module 1 to generate power.

摘要： PURPOSE:To set an adequate electromagnetic force and to save electric power in a bubble separator consisting of a hydrophobic membrane, magnets and electrodes by installing gas detectors in passages on the inflow and outflow sides of a gas-liquid multiphase flow. CONSTITUTION:In a bubble separator consisting of a hydrophobic membrane 3, magnets 6, 6' and electrodes 10, 10', gas detectors 14, 14' are installed in an inflow side passage 4 and/or an outflow side passage 5 of a gas-liquid multiphase flow 8. Since bubble contents are detected at the inlet and outlet, current value is controlled, based on the detected value. Thereby an adequate electromagnetic force can be set in the bubble separator to save electric power. Further, bubble generation from the electrodes can be prevented by setting the upper limit of the current value of the bubble separator and controlling the current value so that it may not exceed the upper limit. In addition, a temp. sensor 20 is installed in the multiphase liquid in the gas-liquid separator to measure temp. which is kept within a range of regulated temp. by controlling the current value. Thereby the temp. is the prescribed value or less and the death of biological samples can be prevented.

摘要： PURPOSE:To parcel components of equal charge accurately and efficiently, by arranging a parcelling hole at the tank thickness-wise center of a sample parcelling section to control the parcelling flow rate so that the speed of inflow from the parcelling hole is almost the same as that of a tank liquid at an upstream point with respect to the parcelling hole. CONSTITUTION:A sample injection tube 2 and a tank liquid introduction tube 4 are provided on the top of a migration tank 1, electrodes 6 and 7 at both ends thereof, a sample parcelling section 3 at the lower part thereof and a tank liquid drain tube 5 on the bottom thereof. In addition, upper and lower detectors 16 and 17 are provided to detect absorbance with the wavelength allowing absorption by components to be separated. A diffusion range of the components is detected with the upper detector 16 from a detection range of absorbance at an upstream position with respect to a parcelling hole 15 while that is detected with the lower detector 17 from a detection range of absorbance at a position immediately before the parcelling hole. The amount of a parcelling liquid is controlled with a parcelling flow rate adjuster 24 to make the detection ranges equal thereby enabling the parcelling of components of equal charge accurately as well as efficiently.

摘要： PURPOSE:To attain a call to an opposite station without disturbing the operation by setting a freely removable memory means storing a telephone number of the opposite station to a reader. CONSTITUTION:The memory means 2 stores plural telephone numbers of opposite parties and is removed freely from the reader 3. Moreover, an indication means 1 indicates selectively the opposite telephone number of the means 2 and a storage means 5 reads the telephone number from the means 2 by the indication of the means 1 and stores it. When the means 2 is set to the reader 3, a control means 4 stores the telephone number of the opposite station indicated by the means 1 to the means 5 and gives a signal to the opposite station.
