Title: Active filter circuit
Inventor: UCHINO MASAFUMI
IPC: H02M7/12
Filed: 1996-07-02
Abstract: PROBLEM TO BE SOLVED: To suppress harmonic currents and make an active filter circuit cope with a general load. SOLUTION: An input AC voltage Vi of AC 100(V) is subjected to full-wave rectification by a bridge rectifier DS. By applying the rectified voltage to the DS side terminal of a coil L1 and switching a field-effect transistor Q1 at a high frequency, the connection between the diode D1 side terminal of the coil L1 and a reference potential GND is opened and closed to make the waveform of an input current Ii sine wave. At the same time, a step-up pulse voltage VQ1 whose peak is approximately 250(V) is induced on the D1 side terminal of the coil L1 and the induced voltage VQ1 is applied to the D1 side terminal of a coil L2 through diodes D1 and D2. The voltage VQ1 is filtered to the level of its average value by a coil-input filter circuit composed of the coil L2 and a capacitor C1 to obtain an output DC voltage Vo of 130-140(V).  It is to be noted that an active filter control circuit 2 controls the switching frequency or the ON-time of the field-effect transistor Q1 so as to make the voltage Vo constant.

Title: Runaway detector for microcomputer
Inventor: FUJII MASAHIKO
IPC: F02D45/00
Filed: 1981-10-29
Abstract: PURPOSE:To detect a runaway easily without adding complicate interval processing to the control flow of a microcomputer. CONSTITUTION:While a microcomputer 6 is normal, an output signal B inverted in polarity at intervals less than a predetermined period is generated at its output port P2 invariably, and an integral output obtained through an inversion detecting circuit 7 and an interpulse integrating circuit 11 never reaches the threshold level Vth of a level comparator 16. Once the microcomputer 6 enters into a runaway state, runaway monitoring software interrupts the inversion of the output signal generated at the output port P2, and then the output D of the interpulse integrating circuit 11 rises above the Vth to trigger a monostable multivibrator 17, which generates an output F to perform fail-safe control and also to reset the microcomputer 6.

Title: Thin-film magnetic head and its production
Inventor: NAKAMURA TSUNEO
IPC: G11B5/31
Filed: 1992-06-30
Abstract: PURPOSE:To shorten the process for production by simultaneously forming the conductor winding and polishing monitor of the thin-film magnetic head and relatively positioning the polishing monitor and interlayer insulating films for a magnetic gap. CONSTITUTION:The first and second interlayer insulating films consisting of SiO2, Si3N4, etc., are formed by a reactive ion etching method to form a front gap part and a pattern 400a is simultaneously formed in the resistor part of the polishing monitor 100. The films 3a, 3b and the resistor 42 are etched. The pattern 400a is parted in the bottom end line upward by a distance M on a photomask to a front gap part 107a. By that, both the gap 107a and the pattern 400a generate the same deviation and also the pattern spreading occurs similarly even if the mis-alignment of the photomask arises, the same pattern forming error arises and the relative distance M does not change. The relative positions of the gap line of the thin-film magnetic head and the top end line of the monitor 100 are then formed always constant.

Title: Costas loop type demodulating system
Inventor: ONO MITSUHIRO
IPC: H04L27/22
Filed: 1989-07-03
Abstract: PURPOSE:To attain stable demodulation by setting a frequency drawing range added to a voltage controlled oscillator control signal larger in the case of the sweeping state and smaller in the case of the tracking state and changing the protection stage number. CONSTITUTION:When the synchronization is stepped-out, a sweeping control signal is inputted from a sweeping/tracking control signal generating section 7 to a loop filter 5. Thus, a voltage controlled oscillator 6 reaches the sweeping mode and the deviation of a phase difference sweeps from -45 deg. to 45 deg.. In this case, the  F is set larger and the protection stage number reaches a value suitable for the sweeping state. When the phase difference reaches a range including 0, since a tracking control signal is outputted from the generating section 7, the oscillator 6 releases the sweeping mode and makes the phase difference completely 0 based on the phase difference signal from a phase detector 4. When the phase difference reaches 0 and the synchronization is finished, the  F is revised into a smaller value than that used so far. In this case, the protection stage difference set by a protection circuit 9 is set to a different value from that in the sweeping state.

Abstract: PURPOSE:To remove complicated control and a detection switch for discriminating an ink ribbon cartridge by providing a bar code different in the number of bars according to the difference of an ink ribbon to the ink ribbon and discriminating the number of the bars of the bar code by a bar code reading means. CONSTITUTION:A color ink ribbon 1' has an upper printing zone 5' and a lower bar code zone 4' and a bar code is printed on the bar code zone 4' using an impervious material in the same way as a case of a monochromatic ribbon. An ink ribbon is fed out in the direction shown by an arrow by a ribbon feed mechanism before the start of printing operation and, when a bar code 10 is detected by a photoelectric detection switch 2, two pulse signals 11 are generated to confirm that the ink ribbon is a color ribbon. Thereafter, the ribbon feed mechanism is stopped. A cyan region 7 is scanned by a printing head to perform the printing of one line and the ribbon is subsequently fed out by definite quantity by the ribbon feed mechanism to feed a magenta region to a printing head part and, thereafter, the same printing as the printing data in the cyan region is performed.

Title: Copying sheet processing device
Inventor: SHIBUSAWA MITSUO
IPC: G03G15/00
Filed: 1988-07-13
Abstract: PURPOSE:To surely staple a bundle of a sheets by automatically setting a sort mode when a staple mode is selected and set, and by inhibiting the stapled mode from being set, if the presence of sheets in a sorter bin is detected at this time. CONSTITUTION:When a staple mode is selected and set, a sort mode is automatically set so that recording sheets 16 discharged from a copying machine body are successively stored in bins 10 in a sorter and are gathered therein by means of feed rollers 15. Further, when the number of recording sheets reaches a predetermined number of pages, a stapler device 11 is successively positioned at bins 10 by the rotation of a drive screw 14, and energization of a solenoid 22 causes each bin 10 or a bundle of recording sheets 16 to be positioned at a stapler 13 which therefore staples the bundle of sheets 16. During setting of this staple mode, if the remaining of the recording sheets 16 previously copied in the bins 10 in the sorter 3 is detected, the setting of the staple mode is automatically inhibited. Thus, it is possible to staple a bundle of sheets which are surely gathered always.

Title: Production of transparent electrically conductive film
Inventor: SHIMIZU JUNICHI
IPC: H01L21/285
Filed: 1994-07-25
Abstract: PURPOSE:To suppress the generation of a lower oxide and joule on the surface of a target by supplying periodically intermittent electric power to the target. CONSTITUTION:A transparent electrically conductive film is formed by using such as the sputtering target consisting essentially of tin or tin oxide. A target consisting essentially of indium or indium oxide and a target consisting essentially of zinc or zinc oxide are exemplified as the other target. The transparent electrically conductive film consisting essentially of the oxide is produced with the tar-get by sputtering method. Then, the intermittent electric power is periodically supplied to the target. A target containing metal antimony or an antimony compound can be used as the target. The voltage waveform in the unit period of the intermittent electric power is controlled to 10mum to 10ms for the time for impressing negative voltage and 10mus to 100ms for the sum of the time for non-impressing and that for impressing positive voltage. In this way, abnormal discharge causing the defect of the transparent electrically conductive film is suppressed.

Title: Measuring apparatus for diffusion layer depth
Inventor: KOTANI SHIGEO
IPC: G01R31/28
Filed: 1991-07-12
Abstract: PURPOSE:To simply accurately measure diffusion depth without forming a special specimen and performing special measurements, by obtaining the diffusion depth of a high concentration region from scanning in the thickness direction of a specimen, by applying the fact that the transmittance or the scattering rate of infrared radiation sharply changes when the impurity concentration in silicon exceeds a specific value. CONSTITUTION:Infrared radiation 13 is generated from an infrared radiation generator 12, and projected on a specimen through a slit 14. The scattered light and the transmitted light of the infrared radiation are detected with a first detector 15 and a second detector 16, respectively. The output of each detector is amplified with an operational amplifier 17, the ratio to previously known infrared radiation intensity is obtained with an operational amplifier 18, and the scattering rate and the transmittance are obtained. In the case of the transferring from N<-> to N<+> in a substrate containing diffusion, the transmittance of infrared radiation sharply falls, or the scattering rate sharply increases. Hence the depth which an impurity diffusion layer reaches can be obtained by finding the scanning position generating the above changes.
