Title: Protecting method for power conversion device against overcurrent
Inventor: KUNO HIROMICHI
IPC: H02H7/122
Filed: 1990-06-18
Abstract: PURPOSE:To protect a voltage control type switching element from overcurrents due to the disconnection of a gate wiring path by applying pulse-shaped test voltage to the gate of the voltage control type switching element and detecting gate currents before DC voltage is charged to a power conversion device and charging DC voltage to the power conversion device. CONSTITUTION:PWM signals are input to each driver circuit 24a-24f from an inverter control circuit 22 under the state in which a switch 16 is turned OFF. Consequently, a transistor(Tr) 42 in the driver circuit 24a is turned ON, pulse-shaped test voltage is applied to the gate of an IGBT 12a through the Tr 42 and a resistor 44, and gate currents IGE are made to flow. When there is abnormality such as an imperfect contact in a gate wiring path 34, gate currents IGE are not made to flow, and currents are not also made to flow through the primary side diode of a photo-coupler 48. Accordingly, a signal at a High level is input to the Dn terminal 56 of an inverter control circuit 22, and the switch 16 is left as it is turned OFF by a switch control circuit 40.

Title: Body identification device
Inventor: HIROSE NORIAKI
IPC: G01V8/10
Filed: 1989-06-22
Abstract: PURPOSE:To improve identification accuracy to an unspecific body which generates a sound and vibration by performing primary estimation based upon frequency analytic data on the sound, vibration, etc., and secondary estimation based upon image data. CONSTITUTION:When a specified sound collection microphone 2 detects a sound, a sound analyzer 3 takes a frequency analysis of its signal and supplies the result to a data collator 6. The collator 6 estimates the body by using only the sound. Similarly, when a specified vibration sensor 4 detects vibration, a vibration analyzer takes a frequency analysis of its signal and supplies the result to the collator 6. The collator 6 estimates the body by using only the vibration and collates composite data obtained by both the analyzers to estimate the unspecified body. Then when the video signal of a CCD camera 7 is supplied, an image multi-valuing processor 8 performs processing and supplies the result to a data collator 9 and an image feature extraction processor 10. The collator 10 estimate the body by using only its image and supplies data obtained by the collator 6 when the body is in an estimated body zone, and the processor 10 performs secondary image processing.

Abstract: PURPOSE: To realize positive-positive printing and negative-positive printing in one machine simultaneously, by applying first image forming radiation and charge to a photosensitive plate, then applying second image forming radiation and AC destaticizing, and further exposing the entire surface uniformly.  
     CONSTITUTION: A photosensitive plate A having photoconductive layer 2 and insulating layer 3 on a conductive supporting body 1 is, for exapmle, negatively charged by a corona discharger 4, and optical image radiation is given at the same time. Then, in the dark part, a positive charge 32 is induced in the vicinity of the body 1 of the layer 2, while in the bright part the positive charge remains between the layer 2 and layer 3. Then, second optical image radiation and AC destaticizing by AC corona discharger 8 are applied to the surface of the layer 3. As a result, the negative charge 31 in the dark part and the positive charge 33 in the bright part previously charged will be discharged. And, by full exposure of the layer 3, in the bright part of the first optical image, the positive charge 33 in the dark part of the second optical imae is extinguished, leaving only the quantity of charge equivalent to the charged load 31 on the surface. Thus, positive-positive printing and negative- positive printing may be realized simultaneously in one machine.

Title: Ceramic multilayer interconnection substrate
Inventor: KUDOU YOSHIYA
IPC: H05K3/46
Filed: 1987-06-29
Abstract: PURPOSE:To eliminate generation of cracks to obtain a ceramic multilayer interconnection substrate with high density by filling the central part of a through hole with an insulating material. CONSTITUTION:A conductive layer 3 for through hole is formed on the inwall of a through hole 2 of a substrate insulating layer 1. A filling layer 6 of the same component as that of the insulating layer 1 is formed in the through hole 2. And a printed conductive layer 4 is formed on each of both surfaces of the substrate body comprising the insulating layer 1 and the filling layer 6. Then, the ratio which the conductive layer 3 forms is so small that the stress, which results from the difference of the thermal expansion coefficient between the insulating layer 1 and the filling members 3, 6 in the through hole 1 and stresses between upper and lower surfaces of the through hole 2, is reduced. As a result, cracks are prevented from being generating in the portion A. Therefore, a ceramic multilayer interconnection substrate with high density can be obtained.

Title: Junction-type field effect transistor
Inventor: SAMEJIMA HIROYUKI
IPC: H01L29/808
Filed: 1989-06-23
Abstract: PURPOSE:To instantly remove surge voltage through a passage to a gate electrode of a FET and thus improve the resistance to static charge by a method wherein a gate region formed on a substrate is electrically connected to the gate electrode through a metal wiring. CONSTITUTION:A gate region 5 formed on the surface of a semiconductor substrate 1 is electrically connected through a metal wiring 8 to a gate electrode formed on the rear of the substrate. Current flowing in the region 5 flows through the low-resistance aluminum wiring 8 and a region 3 to the substrate 1 forming the gate electrode. Thus the time required for current to reach the gate electrode can be shortened even if diffusion resistance of the gate region 5 is large. Therefore when surge voltage is supplied to the gate region 5, it can reach the gate electrode instantaneously through the wiring 8 to be discharged outside. Thus local damage on the gate region can be prevented thereby improving the resistance to static charge.
