Title: Deflection measuring unit of automatic zero correction
Inventor: TARUI MASAHIRO
IPC: G01G23/36
Filed: 1978-09-16
Abstract: PURPOSE: To establish the deflection measuring unit in which zero correction can quickly be made, by obtaining the difference between the output of the first operation unit and the output of the hold unit holding the state of zero before measured object is incoming, by means of the second operation unit in advance.  
     CONSTITUTION: The converter 3 produces a voltage in proportion to the weight of the measured object 1. The reference signal generator 4 provides two output terminals; one outputs the first reference voltage to the weight of dial set and another outputs the second reference voltage equal to the output voltage of the converter 3 when the measured object 1 is not placed on the scale stand 2. The selector 5 selects two types of outputs of the reference voltage generator 4. The timing control unit 7 receives the signal from the position detector 6, to output signals of selector instruction, sample hold instruction, and display instruction. The first differential amplifier 8 operates and outputs the difference between the output voltage of the selector unit 5 and the converter 3. The second differential amplifier 10 operates and outputs the difference between the output voltage of the first differential amplifier 8 and the sample hold circuit 9.

Title: Moisture evaporator
Inventor: KISHI MITSUHIRO
IPC: B01D53/86
Filed: 1988-05-10
Abstract: PURPOSE:To improve the efficiency or evaporation in a water tank and to shorten the time for treatment by constituting the evaporator of the water tank in which water is housed, a block body which is installed in this water tank and has the heat insulating capacity to segment the space in the water tank and a heater which is housed in this block body. CONSTITUTION:Since the block body 14 is slightly lifted by legs 15, the water 19 in the water tank 11 and the water in the block body 14 communicate freely with each other. Only the water existing in the internal space of the block body 14 is heated and the satd. steam is generated from the surface thereof when the block body is heated by energizing the heater 18. The water 19 is thereby successively evaporated. Since the block body 14 has the heat insulating capacity, the heat generated by the heater 18 is not transferred to the side outer than the block body 14 and, therefore, the water 19 existing in the space on the inner side of the water tank 11 and the outer side of the block body 14 is not heated and only the water 19 in the small area in the block body 14 is heated. The water temp. is consequently increased rapidly and the satd. steam is successively evaporated from the inside of the block body 14.

Title: Amplifier
Inventor: KAWASHIMA SHOICHIRO
IPC: G11C11/419
Filed: 1996-05-08
Abstract: PROBLEM TO BE SOLVED: To enhance an operating speed by respectively interposing switching elements in between respective drains of p and n MOS cross couples and VCC and VSS to quicken potential changes after the completion of a reset period. SOLUTION: In a reset period, two rest control signals ϕ1 , ϕ1x being in a complementary relation becomes that the signal ϕ1 =1 and the signal ϕ1x =0 and a pMOS 4 and an nMOS 5 interposed in between a pMOS cross couple 12 are turned ON and, moreover, switching elements 21, 23 respectively interposed in between the drain and VSS and the drain and VCC are also turned ON. As a result, potentials of nodes N1 , N2 in the reset period, that is, potentials of an OUT and an OUTx both become low potentials of the order of VSS≈0 and large potential differences equivalent to VCC-VSS are applied in between sources and gates of pMOSs 2, 3 constituting the couple 12.  Thus, even though VCC is made to be 1V, the threshold voltage of the pMOSs 2, 3 is made to be 0.5V, since voltages between the sources and the gates are larger than 0.5V, the rising of output node is quickened and the high-speed property of an amplifier is never impaired.
