Abstract: PURPOSE:To supply a commutation current to execute reliable cutoff even in the case of abnormal contact parting other than overcurrent detection by measuring an arc voltage of a vacuum valve contact point, and adopting this voltage as one of signals for supplying a commutation current. CONSTITUTION:In protective cutoff of an overcurrent, output of a current detector 4 is input to a control part 10, and according to a trip command thereof a vacuum valve contact point 5 is parted at a high speed to be locked via an electromagnetic repulsion coil 11. After an elapse of a predetermined time, according to a commutation command an oscillating current from a commutation capacitor 9 is supplied to the contact point 5 to artificially set a current of the valve contact point 5 at zero. A resistor 14 is provided between poles of the contact point 5 so as to draw out a generated voltage and transmit it to a control part 10 to adopt it as one of signals for a commutation command. Designing for sufficient voltage withstanding is necessary for the resistor 14 and the control part 10, while cutoff can be executed by providing the commutation current under such a condition as abnormal contact parting of the vacuum valve contact point other than the overcurrent.

Title: Image reader
Inventor: OZAKI TATSUYA
IPC: H04N1/04
Filed: 1999-01-11
Abstract: PROBLEM TO BE SOLVED: To obtain an image reader that can read accurate original picture information by starting reading of an original after carrying the original by a distance resulting from subtracting a carrying distance until it is detected that a tail end of the read object original is carried up to a stamped position from a prescribed distance after a tip of the original passes through a read reference position. SOLUTION: A reference position sensor S2 is a sensor to decide a tip position of an original to detect whether or not the tip of the carried original passes through the position of the sensor S2. Usually a stepping motor is used to carry an original and the position control of the original is executed by managing the number of steps of the stepping motor. Each read object original carried at intervals of one page is sub-scanned on a scan line Ls. A scanner reads the read object original passing through the scan line Ls from its tip to its tail end in the unit of main scanning lines to obtain picture information.

Title: Frequency synthesizer
Inventor: HIDA TSUTOMU
IPC: H04B7/26
Filed: 1998-01-12
Abstract: PROBLEM TO BE SOLVED: To enable high-speed synchronization without increasing a power supply voltage by providing a bypass means for feeding power from a power source to a phase locked loop(PLL) circuit while bypassing a low-pass filter(LPF) during the prescribed time when starting power feeding from the power source. SOLUTION: A PLL-IC 9 is connected through a switch 2, resistor 3 and switch 5 to a power source 1. The resistor 3 removes the unwanted frequency component contained in the power source 1 while consisting of the LPF together with a capacitor 4. When turning on the power source of the PLL-IC 9, first of all, the switch 2 is closed from the state of opening the switches 2 and 5. In such a state, only a charging current flows from the power source 1 through the switch 2 and the resistor 3 to the capacitor 4. Therefore, the inter-terminal voltage of the capacitor 4 gets equal with a voltage VDD of the power source 1.  When the switch 5 is closed and the power source of the PLL-IC 9 is turned on in the state of turning the inter-terminal voltage of the capacitor 4 to VDD, a current flows to the PLL-IC 9 so that a discharge current flows from the capacitor 4 and the inter-terminal voltage is decreased.

Title: Fitting structure of valve casing seat in eccentric valve
Inventor: TANAKA YOSHIHARU
IPC: F16K5/04
Filed: 1998-01-12
Abstract: PROBLEM TO BE SOLVED: To improve the productivity by holding a valve casing seat on both end faces in the axial direction of a valve casing seat between a stop ring to be fitted to a stop ring fitting groove and a stepped surface between a valve port part and a large diameter part to dispense with a male screw in the valve casing seat and a female screw in a valve casing. SOLUTION: A stop ring 15 is formed of a hard metallic plate which is relatively high in elasticity. The thickness is set to a value slightly smaller than the width of a stop ring fitting groove 14. The outside diameter in a natural condition is set slight smaller than the inside diameter at the bottom of the stop ring fitting groove 14, i.e., the maximum inside diameter. The outside diameter is set so that the stop ring can be attached/detached to the stop ring fitting groove 14 in an elastically contracted condition in the radial direction. A fitting condition of a valve casing seat 9 can be obtained where both ends in the axial direction of the valve casing seat 9 are held by the stop ring 15 to be fitted to the stop ring fitting groove 14 and a stepped surface 12.  The productivity can be improved because conventionally required threading for the valve casing seat 9 and a valve casing 1 can be dispensed with.

Title: High frequency analog switch
Inventor: KOMATSU KAZUHIRO
IPC: H03K17/687
Filed: 1999-01-11
Abstract: PROBLEM TO BE SOLVED: To provide a high frequency analog switch capable of surely preventing the leakage of high frequency interference signals. SOLUTION: The main signal routes of a first switching means 21 and a second switching means 22 are connected through a main signal route high frequency interruption means 23 which is a grounded capacitor for instance. Control signals to the first switching means 21 and the second switching means 22 are supplied through a control signal route high frequency interruption means 24. Thus, among the high frequency interference signals flowing between the input/output terminals of this analog switch, the high frequency interference signals flowing through the main signal route are interrupted by the means 23 and the high frequency interference signals flowing through a control signal route are interrupted by the means 24. Thus, the leakage of the high frequency interference signals is surely prevented.

Title: Manufacture of nickel electrode for alkaline storage battery
Inventor: IWAKI TSUTOMU
IPC: H01M4/26
Filed: 1991-01-18
Abstract: PURPOSE:To provide the manufacture of a nickel electrode for an alkaline storage battery improving the utilization factor of an active material and increasing the volume efficiency and weight efficiency at a low cost, particularly the manufacture of the nickel electrode used for the alkaline storage battery such as a nickel-cadmium storage battery or a nickel-hydrogen storage battery. CONSTITUTION:A nickel electrode obtained by directly using nickel hydroxide has the utilization factor of nickel hydroxide slightly lower than that of the sintered type. Cobalt is effective in particular including the sintered type to improve the utilization factor, however, the absolute capacity is decreased if too much cobalt is added. The nickel electrode used for an alkaline storage battery is mainly made of nickel hydroxide added with cobalt powder, and it is heated at 120-170 deg.C in the atmospheric air so that the low potential caused by cobalt is not extinguished. Carbonyl cobalt is preferable for the cobalt used here, and the cobalt powder about 3-15wt.% is preferably added to nickel hydroxide.
