Patent JP-S62218858-A (JP)
Title: Oxygen concentration detector
Inventor: ASAKURA MASAHIKO
IPC: G01N27/409
Filed: 1986-03-19
Abstract: PURPOSE:To prevent a possible blackening phenomenon, by a method wherein a voltage value command to a delay means is stopped when a voltage between electrodes of a battery element reaches a first specified value and when it exceeds a second specified value, a pump current is reduced sharply. CONSTITUTION:A current is supplied to between electrode plates 5 and 6 of an oxygen pump element 1 from a current supply circuit 11. A voltage value command indicating a voltage between electrode plates 7 and 8 from an Ic output end of an air/fuel ratio control circuit 31 is supplied to a voltage division circuit 36. As a voltage Vs between the electrode plates 7 and 8 of a battery element 2 rises, an output voltage Vs' of a non-inversion amplifier 30 goes up to invert an output of an operational amplifier 41 from a low to high level so that a connection line between the circuit 36 and an integrating circuit 39 will be almost equal to the earth potential. An electric charge of a capacitor 38 flows to the earth to lower a pump current gradually with a gradual drop in a reference voltage. As the pump current rises so high as to attain a range of causing a blackening phenomenon and the voltage Vs exceeds a second specified value, a transistor 13 is turned OFF to reduce the pump current sharply.

Title: Polysulfone-base separating membrane and its production
Inventor: UCHIDA YASUO
IPC: B01D71/68
Filed: 1979-05-24
Abstract: PURPOSE: To obtain the separating membrane which is superior in water permeability and mechanical strength by dissolving polysulfone resin and epoxy resin into a polar organic solvent and flow-casting the same to membrane-form or pipe-form then dipping the same into water.  
     CONSTITUTION: Polysulfone resin is mixed with, for example, epoxy resin of a softening point of preferably 40°C or more corresponding to 1% thereof and the mixture is dissolved in a polar organic solvent such as N-methyl-2-pyrolidone or the like and is subjected to wet type filming by conventional methods. Since this solution does not cause any white clouding and precipitation, the separating membrane formed retains the required mechanical strength without decreasing water permeability.

Filed: 1980-05-12
Abstract: PURPOSE: To obtain strontium titanate particles grown in the crystal axis direction and useful as starting material for a ceramic dielectric material by mixing potassium titanate fiber with strontium oxide and calcining the mixture to cause a reaction.  
     CONSTITUTION: One mole potassium titanate fiber represented by formula K 2 O. nTiO 2  is mixed with n mole strontium oxide or a strontium compound such as strontium hydroxide or strontium carbonate convertible into strontium oxide by decomposition at a high temp. The mixture is calcined to cause a reaction by which a strontium component is substituted for a potassium component in the potassium titanate fiber. Thus, SrTiO 3  crystal particles grown in the crystal axis direction are formed. A K-base component formed by the liberation is then removed with water or acid to take out desired SrTiO 3  crystal particles.

Title: Binary system logic dividing method and device requiring no operating clock
Inventor: KANAI KIYOSHI
IPC: G06F7/52
Filed: 1991-03-28
Abstract: PURPOSE:To unnecessitate operating clock and to shorten the dividing time by providing continuously plural circuits which perform the division processing of a dividend with the Y bit width of the divisor data in response to the digits of the dividend data. CONSTITUTION:A comparison subtractor 3 performs the division processing by inputting the binary values of both dividend and divisor date into a dividend register 1 of the X-bit width and a divisor register 2 of the Y-bit width. Then (X-Y+1) pieces of subtractors 3 are arranged on a pipeline. In such 8 constitution, the quotient of (X-Y+1) bits and the remainder of Y bits are obtained by those subtractors 3 arranged on the pipeline and with no use of an operating clock just by inputting the binary dividend X and divisor Y into the registers 1 and 2 respectively. Thus it is possible to obtain a calculation result equal to the conventional one in an extremely short time dependent on only the switching speeds of the circuit component elements.
