Title: Manufacture of nickel hydroxide electrode for alkaline storage battery
Inventor: OTSUKI KOZO
IPC: H01M4/26
Filed: 1987-09-21
Abstract: PURPOSE:To prevent the corrosion of a porous nickel substrate even in high temperature, high concentration impregnation solution by specifying the specific conductivity of a nickel nitrate aqueous solution, in which the porous nickel substrate is immersed for alkali treatment, in a specific range. CONSTITUTION:A porous nickel substrate is immersed in a nickel nitrate aqueous solution, then alkali-treated to convert nickel nitrate into nickel hydroxide. By repeating this process, a desired amount of nickel hydroxide is impregnated in the porous nickel substrate. The nickel nitrate aqueous solution having a specific conductivity of 3.0X10<-2>-5.0X10<-2>OMEGA<-1>/cm is used in this process. Even if the nickel substrate is immersed in high temperature, high concentration nickel nitrate aqueous solution, the corrosion of the substrate is retarded. As a result, an alkaline storage battery having steady cycle life can be obtained. To adjust the specific conductivity, the addition of nitric acid and nickel hydroxide is preferable in terms of the easy control of an impregnation solution and the prevention of contamination.

Title: Output circuit
Inventor: NAKAO KENJI
IPC: H01L21/8238
Filed: 1990-09-06
Abstract: PURPOSE:To reduce ringing and switching noise with simple circuit constitution and small number of elements by connecting a constant current source in series between the inverter of an inverter output circuit composed of CMOS and a power supply connection section and limiting a current supplied to an output inverter. CONSTITUTION:When an input falling from Vdd to Vss is fed to an input terminal 1, a P-channel transistor(TR) 4 being a component of an inverter is turned on and an N-channel TR 5 is turned off. A load capacitor CL is driven by the P-channel TR 4 and the output voltage is changed from a Vss (low) level to a Vdd (high) level. Since the load capacitor is driven by a constant current through a constant current source 6, ringing or switching noise due to load capacitance and inductance by wiring, etc., is reduced. Thus, the output circuit is formed with the simple circuit constitution and the small number of components and ringing and switching noise in output are reduced.

IPC: H01L39/22
Filed: 1990-09-07
Abstract: PURPOSE:To largely reduce the number of wires and simply enable multiplexing without requirement for improving freezing ability by applying equal constant voltage to superconducting loops of a plurality of SQUIDs and adding output current to be taken out. CONSTITUTION:Equal bias voltage is applied to superconducting loops 2a of a plurality of SQUIDs 2 through a bias voltage line 3a, and in order to cancel a change in flux input from an input coil 2b to the loop 2a, modulation MO current is supplied to an MO coil 2c to attain flux locking. Since output current from all of the loops 2a is taken out in a summed state, correlation between the summed current and a serial symbol C(t) is taken with a multiplier 5b provided on a flux lock loop 5 to integrate 5c one cycle so as to obtain the original MO current. In such a constitution, the number of the voltage lines 3a and current take-out lines 3d are two each irrespective of the SQUIDs 2 connected in parallel, so that they can be reduced to 4 + 2 lines, wherein numerous SQUIDs can be housed in series in a freezing vessel and simultaneous flux measurement is possible.

Title: Injection timing controller for electronic fuel injection device
Inventor: KUDOU ICHIROU
IPC: F02D41/36
Filed: 1983-12-16
Abstract: PURPOSE:To improve drivability ever so better, by quickening an injection start in time of low load but making the injection start slow in proportion to an increase in the load, in case of a system which independently performs the fuel injection with such timing as corresponding to the valve on-off timing at every cylinder at less than the specified engine speed. CONSTITUTION:In time of operating an engine 7, an injector 8 is controlled at a control unit 4 on the basis of each output signal out of a crank angle sensor 13 and an air flow meter 5 so as to make it perform the injection of fuel at every cylinder at the injection start timing commensurate to a load condition at less than the specified engine speed. And, making a top dead point after ignition a criterion, the injection is quickly started in time of low load, while dwell time is made longer till a suction stroke starts because of the injection time being shortened. In time of high load, the injection is slowly started, and as the injection time is long, the dwell time is shortened to a state of being almost nothing. With this constitution, not only a stable combustion state is secured but also favorable accelerating performance is securable.

Title: Position detecting method
Inventor: KATAOKA MINORU
IPC: G01D5/249
Filed: 1986-10-07
Abstract: PURPOSE:To secure position detection even when the moving speed of an object of detection becomes fast by providing incremental codes with specific pitch and absolute codes with specific pitch finer than said pitch to a rotary disk. CONSTITUTION:The rotary disk 22 coupled with the object 20 of detection is given with the incremental codes 23 at the pitch theta1 and further provided with the absolute codes 25 which have the finer pitch theta2 and circulate by displacement of the pitch theta1. While the object 20 is in fast rotation, a pickup 24 outputs accurate A- and B-phase incremental signals of low frequency to a discriminator 38 to generate an accurate direction signal and position pulses, which are counted by a counter 39. Therefore, when the counted value is regarded as high-order data and an absolute code signal is regarded as low-order data, position data is obtained with accuracy based upon the pitch theta1 as resolution. Further, while the object 20 is in slow rotation, a pickup 26 outputs an accurate absolute code signal, which is led to a position detection part. Thus, high-accuracy position data based upon the pitch theta2 as resolution is obtained.

Title: Radiation image-processing method and device therefor
Inventor: YASUDA HIROAKI
IPC: H04N1/04
Filed: 1996-09-10
Abstract: PROBLEM TO BE SOLVED: To segment processing processes quickly at the occurrence of a fault and to specify the fault by storing an intermediate image signal obtained at least in one processing process, other than the final processing process among a plurality of processing processes into a prescribed storage medium. SOLUTION: Each image signal obtained respectively by scanner reading, subscanning reduction and pixel density conversion is stored respectively as intermediate image signals 1a-1c. Since the intermediate image signals 1a-1c are stored in this way, a fault occurrence location is located by checking the intermediate image signals 1a-1c at the occurrence of a fault. That is, suppose that a fault takes place in the processing process of the subscanning reduction processing, only the intermediate image signal 1a is normal, and the intermediate image signals 1b, 1c are erroneous image signals which are different from the intermediate image signals which should be obtained by the processing of the subscanning reduction or the pixel density conversion substantially, so that the fault occurrence position is found to be in the subscanning reduction process.

Abstract: PURPOSE:To surely clean off the dust, etc., in a long-sized or partly bent pipe by inserting a hose provided with a discharge port opened at a desired angle to the rear at its tip into the pipe and sending compressed air into the hose. CONSTITUTION:A nozzle 11 is inserted into one opening 20 of a pipe 2 to be cleaned, and compressed air 17 is supplied through a hose 19.
