Title: Machine motor driver
Inventor: MORI OSAMI
IPC: H02P3/18
Filed: 1990-06-13
Abstract: PURPOSE:To protect a discharge circuit against overvoltage without depending on a fuse by stopping discharge until output voltage of a DC power supply drops below a predetermined level and sustaining power supply to conducting phase windings. CONSTITUTION:When the voltage of an AC power supply 3 exceeds a rated voltage and thereby a source voltage VDC exceeds a voltage limit Vref, a remarkably larger amount of charge is stored in a capacitor 5b as compared with regenerative charges and several mS to several seconds may be required for the source voltage VDC to drop below the limit voltage Vref through discharge of capacitor. When the discharge time exceeds a time limit, logic signal S3 of a flipflop FF goes Low thus pulling the stop signal Sstop of an AND circuit Low. Consequently, a transistor Trd is turned OFF to stop discharge. At the same time, output signals S3 from the flipflop FF are fed to a conduction control circuit 20 and a latch circuit 30 and a phase winding current 1 having maximum current level is fed to phase windings Lu-Lw thus protecting a discharge circuit 9 without blowing a fuse F.

Filed: 1989-06-19
Abstract: PURPOSE:To remove attraction due to static electricity generated between a glass plate and an original by discharging static electricity charged on the glass plate to a reading part through a destaticizing part to be moved in contact with the glass plate. CONSTITUTION:When an original inserted from a hopper part is set up on the glass plate 7 of a body part, the reading part 8 starts scanning. The light of a fluorescent lamp 12 projected from a slit 14 is reflected on the original through the glass plate 7, made incident again from the slit 14 and reached to the surface of a CCD 19 through respective reflectors 15 to 17 and a lens 18. A signal outputted from the CCD 19 is outputted to the external at a required timing. The read original is discharged to a stacker part through a printer part. Since a destaticizing brush 22 is contacted with the rear face of the glass plate 7 over the whole width, the brush 22 is slided on the whole surface of the glass plate 7 when the reading part 8 scans the original in the direction (B direction) rectangular to the width. Consequently, a comparatively large part of static electricity charged on the surface of the glass plate 7 can be discharged.

Abstract: PROBLEM TO BE SOLVED: To make settable the operating condition of a semiconductor device by using an existing pad used for another purpose by a constitution wherein the time which the elapsed since a signal which initializes the semiconductor device becomes invalid is counted and the operating condition of the semiconductor device is decided according to a counted contact. SOLUTION: An information processing part 102 and an input/output processing part 101 are provided. In the input/output processing part 101, an operating-mode setting part 100 which is composed of a timer 200, a decoder 202 and a register 201 is contained. The timer 200 counts a clock signal up to its upper-limit value so as to be retained when an initialization reset signal 220 is inputted. The decoder 202 decodes the output of the timer 200, it outputs a signal 223 which indicates whether an operating-mode setting operation is within an effective period or not, and it outputs a signal 224 which permits the operation of the information processing part 102. The register 201 retains the output signal 222 of the register 200 when the operating-mode setting operation is within the effective period, and the operation of this semiconductor device is decided by the output signal.  By this constitution, even when an operating- condition setting command is not set at a modulation-demodulation circuit 206 and a modulation-demodulation circuit 207, it is sufficient to handle a demodulated data signal.

Title: Measuring method of high temperature to melt down thermocouple
Inventor: OONO JIROU
IPC: G01K7/02
Filed: 1977-12-23
Abstract: PURPOSE: To measure accurately the high temperature to naturally cause a thermocouple to melt down, without disturbing the ambient temperature, by estimating the final reaching temperature or the ambient or environmental temperature, when a thermocouple is burned out, from the temperature elevating status until the burnout.  
     CONSTITUTION: When a consumable probe holding a thermocouple is placed in the atmosphere at temperature θ 0 , the output of the thermocouple elevates while showing a capacitive delay, and the temperature of the thermocouple placed in the  probe central axis conforms to formula I. Te ith-order (i=1, 2, 3...) differential  coefficients of formula I are obtained successively, and the relation between the  sum obtained by multiplying a proper coefficient Ti to each differential coefficient  and θ* obtained by adding θ (τ , 0)  thereto conforms to formula II. By selecting the coefficient Ti properly, θ (τ , 0)  becomes constant in a short time, and this constant value gives temperature θ 0 . Namely, when Ti is properly selected, a correct ambient temperature θ 0  may be obtained even if the output of the thermocouple θ (τ , 0)  is  in the low temperature range.
