Abstract: PURPOSE: To make the suction and exhausting of ion wind good and even by comparing the potential in the central part in the lengthwise direction of the two side faces of a conductive shield not opposing to a photoreceptor with the potential at the end part in the lengthwise direction and making these relatively close to the potential of a discharge electrode.  
     CONSTITUTION: A conductive shield 11 consists of a back plate 11b opposing to a photoreceptor 3 and parallel side plates 11c, 11c which do not opposite thereto. Insulation members 18 are secured on the insulation plates 16 bonded to the plates 11c, over the length l in the central part in the lengthwise direction of a discharge device 1. The members 18 are provided nearly sysmmetrically on the right and left, with discharge wires 14 in-between and the length l is selected within the specified range with respect to the effective discharge length L of the device 1. The width of the members 18 is so determined that the position relations of the wires 14, shield 11 and photoreceptor 3 are set in such a manner that at the time of discharging the corona current flows more toward the shield 11 than toward the photoreceptor 3.

Filed: 1988-02-02
Abstract: PURPOSE:To maintain automatically the proper mold temperature at all times by providing a heat medium temperature sensor on the mold outlet side of branching pipes and controlling the opening degree of flow rate regulating valve of the branching pipes by means of signals of respective sensors. CONSTITUTION:Temperature sensors S1, S2 and S3 are provided on the mold outlet side of respective branching pipes 11, 12 and 13 to sense the temperature of heat mediums after heat exchange in a mold 2. When the temperatures T1, T2 and T3 of respective heat mediums are sensed and the average value Tm is computed, the opening degree of a flow rate regulating valve 41 is regulated by a controller 7 so that T1 is equal to Tm. Similarly, flow rate valves 42 and 43 are regulated so that T1 and T3 are also equal to Tm. When the heat medium temperatures T1, T2 and T3 on the mold outlet side are maintained equal to Tm, a number of heat mediums flow in a high temperature section in the mold 2 to uniform the temperature distribution of the whole mold and to enhance molding quality.

Title: Variable voltage starter
Inventor: KAWABE TAKAO
IPC: H01F29/02
Filed: 1981-02-18
Abstract: PURPOSE:To smoothly start with a strong acceleration torque by utilizing a part of a start compensating coil wound on a closed magnetic path to form a reactor starter. CONSTITUTION:When a switch S1 is closed, a reduced voltage EM1 by a coil T1 is applied to a motor M. Then, a switch S1 is opened, and switches S2, S3 are closed. Thus, a voltage of EM2=(T1+T3)/(T1+T2+T3) is applied to the motor M. When the rotation of the motor M is raised, the switch S3 is opened, the switch S4 is closed, the switch S2 is opened, and full voltage is applied to the motor M. Even if the switches S1, S2 are superposed to be closed when the switch S1 is opend and the switch S2 is closed, the currents flowing through coils T1, T2 becomes I1T1=I2T2, and the closed magnetic path 1 becomes noninduction circuit. Accordingly, it is not shortcircuited.

Abstract: PROBLEM TO BE SOLVED: To reduce the power consumption by quickening turn-on of an output stage transistor (TR) in a level shift circuit and setting a rapidly increasing current to be supplied at state transition to be an optimum value. SOLUTION: The level shift circuit 40 has a signal voltage level conversion circuit 30' whose node N2 is not connected to a gate G of an output stage MOSFET 5 and an output buffer circuit 50 charging/discharging a gate capacitance C5 of a flip-flop FF rapidly based on a node voltage Vg of the M0SFET5 and an inverting input signal VIN. As soon as the input signal VIN descends and a MOSFET2 is closed and a MOSFET1 is open, a charging MOFET52a is closed. A rapidly increased drain current flows to the MOSFET2, but since a gate of a MOSFET5 is not connected to the node N2 , the voltage at the node N2 is rapidly dropped, a MOSFET3 is immediately closed to discharge a capacitor C. and a discharge MOSFET 54a is immediately open.  Since a capacitor C, is rapidly charged through the closed MOSFET 52a and an output voltage VOUT is rapidly dropped, the MOSFET5 is quickly turned on, Th throughperiod is short and the power consumption is reduced.

Abstract: PURPOSE:To provide a character recognizing device which can properly detect even small defaced parts of characters and also can properly reject the defaced characters without requiring the jobs to previously register such characters that are easily defaced and with high accuracy, high operability and high performance. CONSTITUTION:A contour tracking part 132 extracts a contour out of an input character pattern, and a local line width extracting part 134 extracts the local line width based on each picture element of the extracted contour. A deciding part 135 compares the local line width with the average character line width obtained from the input character pattern to decide the presence or absence of the defaced parts of characters. Thus the defaced parts of characters can be accurately detected. Furthermore it is not needed to previously check and register such characters that are easily defaced or that easily produce the misreading result due to the defacement. Therefore even a beginner user can simply operate a highly accurate character recognizing device.
