Title: Gate controlling circuit for gate turn-off thyristor
Inventor: TAKIGAMI KATSUHIKO
IPC: H02M1/08
Filed: 1979-09-06
Abstract: PURPOSE:To intercept the Zener current of a gate turn-off thyristor, by setting the maximum voltage across the gate and cathode of the GTO thyristor, its forward voltage interception capability recovery time and the turn-off voltage and turn-off time of a diode in prescribed relations. CONSTITUTION:In the controlling circuit which turns off the gate turn-off thyristor by applying a negative gate pulse to its gate, the maximum voltage vGmax across the gate and cathode of the thyristor, its forward voltage interception capability recovery time T and the turn-off voltage vfr and turn-off time tfr of a diode connected across the gate and cathode of the thyristor are related to each other as vfr>= vGmax and tfr>>T. The voltage vG across the gate and cathode of the gate turn-off thyristor can be kept near the maximum voltage vGmax by the voltage relation. The inflow of the Zener current into the thyristor after turn-off can be prevented by the time relation.

Title: Analyzer with electricity removing function
Inventor: KAWAI KUMIKO
IPC: G01N23/225
Filed: 1988-05-13
Abstract: PURPOSE:To restrict the occurrence region of the electricity removing effect and remove electricity regardless of the shape of a sample and without requiring the pre-processing by installing an electrode which can perform a discharge in a sample chamber. CONSTITUTION:A sample 16 is mounted on a sample bed 3, a chamber 1 is exhausted by an exhaust system 7. An electron beam is accelerated by a high- voltage power source 13 and radiated to the sample while being scanned by a scanning power source 10. Secondary electrons are generated by primary electrons radiated to the sample 16 and fed to a secondary electron detector to form the two-dimensional image of the sample on a CRT 9. When the sample 6 is an insulator, the electric field is generated around the sample, a primary electron beam is bent by its effect, thus a screen is distorted. An electrode fine adjustment device 14 is operated to operate a discharge electrode 6 while the screen of a CRT 16 is observed and a discharge high-voltage power source 15 is set to plus. A discharge occurs between the electrode end and the sample 16, plus charges are moved to the sample surface. When the discharge is maintained on the sample surface by the electrically balanced voltage, a picture with no distortion can be observed on a screen.

Title: Controller for motor
Inventor: YAMAUCHI SATOMI
IPC: H02P25/16
Filed: 1986-05-21
Abstract: PURPOSE:To eliminate the necessity of preparing various types of ROMs by automatically switching control systems of a main circuit by coding a connector provided on a sole control printed board to eliminate an erroneous operation. CONSTITUTION:Main circuits M1, M2, M3 and a common controller C0 are used, and the connections between the man circuits and the controller are executed by switching between the connectors 43, 44, 45 coded, for example, by 3 bits and a common connector 42.

Title: Detector for abnormality of photo coupler circuit
Inventor: KATOU TOMIO
IPC: H01L31/12
Filed: 1977-09-27
Abstract: PURPOSE: To prevent malfunction by detecting the abnormal increase in dark current of a photo coupler circuit and abnormal decrease in coupling efficiency in their earily stages while carrying on the operation of the system.  
     CONSTITUTION: When the dark current of photo transistor 12 surpasses the highest allowable limit, output C of comparator 18 becomes low in potential L and an abnormal signal appears at output E of exclusive-OR 16. When the output of element 12 is more than a photo detection current and also above the lowest allowable limit value which corresponds to the lowest coupling efficiency, input erminals (a) of comparators 14 and 18 are both lower in potential than reference input terminals (b) and otuputs C are "L", so that circuit 16 will not output an abnormal signal. When the output of element 12 is below the lowest allowable limit value owing to a derease in coupling efficiency, the outputs of comparators 14 and 18 are "H" and "L" respectively, so that an abnormal signal will appear at output terminal E. By power supplies Vth and VR 2 , reference potentials of comparators are adjusted, and after abnormality is detected in its earily stage, a tolerant period is given, thereby making it possible to evade malfunction

Abstract: PROBLEM TO BE SOLVED: To improve data processing efficiency by collecting plural similar data as one data group to constitute the plural data groups and time-divisionally transmitting the respective data groups. SOLUTION: The data decoding circuit 300 of a transmission side device 100 decodes data. They are collected into three data groups of A, B and C. They are outputted to a time divisional data output control circuit 500.

Only data corresponding to the respective reception devices 600, 700 and 800 are outputted. Thereby, an address decoder circuit is not necessary for a reception side device and constitution can be simplified. Thus, the reception side devices can be miniaturized.

Title: Circuit for driving ultrasonic motor
Inventor: ICHIKAWA SATOSHI
IPC: H02N2/00
Filed: 1990-05-07
Abstract: PURPOSE:To avoid the increase of a reactive current applied to a piezoelectric device caused by a temperature variation and improve the efficiency over the whole range of the operating temperature by a method wherein a bound capacitance is determined from the temperature of the piezoelectric element which reaches a steady state and a capacitance C having a temperature coefficient opposite to that of the bound capacitance Cd is so provided in parallel with the bound capacitance that Cd+C= constant. CONSTITUTION:A piezoelectric element is bonded to an aluminum bronze stator with Tg 200 deg.C epoxy adhesive. For instance, if a bound capacitance is 9.7nF at 20 deg.C, an inductance L which makes an L-C parallel resonance frequency 40kHz is 1.6mH. If such parallel circuit is used under 100 deg.C, the parallel resonance frequency is declined to 34kHz, shifting from the driving frequency of an ultrasonic motor significantly and a large reactive current is made to flow. In order to cancel the reactive current, a capacitance C whose temperature characteristics is opposite to that of the capacitance of the ultrasonic motor is provided in parallel. As resultant capacitance at that time is simply the sum of the capacitance, the capacitance C is so selected that Cd+C= constant.

Filed: 1995-02-24
Abstract: PURPOSE: To eliminate the gap by previously applying a thermoplastic tape to a pad and punching the thermoplastic tape and the pad simultaneously thereby ensuring the positional accuracy between the tape for bonding an IC chip and a pad through hole. CONSTITUTION: A thermoplastic tape 3 and a pad are punched simultaneously such that a predetermined shape is obtained without limiting to one direction on the surface and rear thus preventing the positional shift between a through hole 4 of the thermoplastic tape 3 and a through hole 2 of the pad 1. Consequently, peel off of an IC chip and cracking of package can be prevented. Furthermore, sealing material is fed through the through hole 2 of the pad 1 at the time of packaging thus bonding the pad 1 and the IC chip 5 rigidly. With such structure, sufficient durability can be held even when the pad 1 is subjected to thermal stress.
