Patent JP-S60206307-A (JP)
Title: Electronic circuit
Inventor: NISHIMURA KIYOMITSU
IPC: H03F1/00
Filed: 1984-03-30
Abstract: PURPOSE:To eliminate the click noise from an amplifier which is generated at a bias switching time, by starting the operation of a bias selecting circuit a certain delay time after the input time of a bias selecting signal and generating an output stop signal from the same time as the input time of the bias selecting signal for a period longer than said delay time and muting the amplifier by the stop signal. CONSTITUTION:Though a logical high level is impressed to a terminal 104 at a time T, switching between bias circuits 3 and 4 is not performed simultaneously with this impression by a delay circuit 6, and this switching is delayed to a time T2. At the time T2, the bias circuit 3 stops the operation, and the bias circuit 4 starts the operation, and simultaneously, an amplifier 2 starts the operation, and the voltage of its output terminal 102 is varied. However, a pulse is generated from a pulse generator 7 during the period from a time T1 to a time T3, and a low frequency power amplifier connected to the succeeding stage of the amplifier 2 is cut off (muted) by this pulse. Therefore, the click noise is not generated because the low frequency power amplifier is not operated before and after the time when the output of the amplifier 2 is outputted.

Abstract: PURPOSE: To control the temperature difference between supply and drain waters to an adequate  value as a whole system of a generating plant, by automatically regulating a flow rate of cooling  waters in the cooling water system partially of a unit among a plurality of sets of condensing  turbine units.  
     CONSTITUTION: A preset signal of a setting unit 21 for the temperature difference between supply  and drain waters is input to a deviation arithmetic unit 25 with an actual temperature difference  obtained by an arithmetic unit 24 of the temperature difference between supply and drain waters,  that accepts signals from a supply water temperature detecting unit 22 and drain water port  temperature detecting unit 23, to obtain a deviation signal of the temperature difference. This  signal is processed in a processing unit 26 of the deviation signal of the temperature difference to  obtain a signal for cooling water amount. While signals from detecting units 27W29 for each  generator output are applied to an adder 33 via arithmetic units 30W32 of cooling water flow rate  to obtain a signal of cooling water amount for the purpose of limiting the temperature difference  between supply and drain waters to a specified value as an integral system of the generating  station. Those of the above two singals for cooling water amount are added by an adder 35 and  applied to a processing unit 36 as a command signal of cooling water flow rate to perform a  control operation for controlled units.

Filed: 1988-03-17
Abstract: PURPOSE:To obtain a ceramic porous material having excellent thermal shock resistance and high strength, by molding a ceramic raw material containing a specific pore-forming material and removing the pore-forming material from molded articles. CONSTITUTION:A ceramic raw material containing a pore-forming material is molded to give molded articles, from which the pore-forming material is removed and which are sintered to produce ceramic porous materials. In the operation, a granular resin having <=60% compression ratio is used as the pore- forming material. The particle diameters of the pore-forming material are preferably <=2mm, most preferably <=0.5mm. When the particle diameters of the pore-forming material are extremely enlarged, there is tendency to reduce moldability and to cause cracks in green bodies, consequently strength of molded article is lowered. Polymers such as polyethylene, polypropylene, polyvinyl chloride, polystyrene and copolymers thereof may be cited as the kinds of the applicable pore-forming material. In actual use, the polymer or copolymer is preferably mixed with >=0.1% crosslinking agent such as divinylbenzene.
