Title: Gate drive circuit for voltage drive element
Inventor: ABE YASUSHI
IPC: H02M7/537
Filed: 1997-11-20
Abstract: PROBLEM TO BE SOLVED: To obtain a gate drive circuit which reduces a loss generated at a time when a short-circuit current is cut off. SOLUTION: When a circuit detects that a short-circuit current Ic flows to a voltage drive element such as an insulated-gate bipolar transistor(IGBT) or the like, a transistor TR4 which is shown in (a) is turned on. Thereby, as shown in (b), the gate-emitter voltage VGE of the IGBT is lowered down to the Zener voltage of a Zener diode ZD10. As a result, the short-circuit current Ic is reduced, and the burden of the IGBT is reduced at the initial stage of a short circuit.

Filed: 1989-12-08
Abstract: PURPOSE:To improve reliability for a line switching device of N:1 by providing a bypass route on which a main signal to be inputted to switches for transmission terminal and reception terminal is inputted directly to a corresponding line in current use when the switch is not operated normally at every switch. CONSTITUTION:A branching circuit 1T on the bypass route for transmission terminal branches the main signal to be inputted to the switch T SW for transmission terminal of each of the N lines in current use to two, and sends one to the switch T SW for transmission terminal of its own line, and the other to the switch 3T of another panel. The switch 3T of another panel always cuts off one of the main signal branched by the branching circuit 1T, however, connects it to the input of a synthesis circuit 2T by performing an operation when the switch T SW for transmission terminal of its own line. The synthesis circuit 2T connects one of branch output of the branching circuit 1T to the input of the synthesis circuit 2T by operating the switch 3T at the time of taking out the switch T SW of the transmission terminal, then, it is outputted from the circuit 2T. Therefore, the main signal to be inputted to its own line is not cut off with the bypass route.

Inventor: YOSHIDA HARUHIKO
IPC: H01L21/28
Filed: 1988-12-20
Abstract: PURPOSE:To reduce serial resistance between a source and a gate in the conditions that enough gate dielectric strength is kept by forming the high impurity concentration layers of a source and a drain, with a low concentration layer between, which is wider by some width than a gate electrode junction part. CONSTITUTION:A resist pattern 2, whose side face is a reversed taper shape, is formed on the surface 1 of a GaAs substrate 1 which has an n-active layer, and thereon an insulating film 3 and a resist 4 are formed. By ashing, etc., the resist pattern 2 and the resist 4, which is applied on the insulating film 3, are removed, and a gate metal 5 to become a gate electrode is deposited on the surface of the substrate. Next, when the insulating film 3 is removed by etching, the deposited metal 5 on the insulating film 3 which covers the surface of the substrate is removed, and only a gate electrode, whose side face is a reversed taper shape, is left. When ion implantation in high concentration is performed with this gate electrode as a mask, the high impurity concentration layers (n<+>) 6 of a source and a drain are formed with a low concentration layer (n) between which is l in width from the junction part of the gate electrode 5, whereby enough gate dielectric strength can be secured.

Title: Color video camera apparatus
Inventor: FUJITA NAOYA
IPC: H04N5/232
Filed: 1991-11-08
Abstract: PURPOSE:To prevent object images from being superimposed and to perform screen synthesis in a form that each object image on first and second lens sides can be observed by driving two image pickup elements with separate driving pulses, respectively, and shifting the optical axes of the image pickup elements electrically. CONSTITUTION:The image pickup element 2 on the first lens side is driven with ordinary horizontal reference pulse HD and vertical reference pulse VD1. The image pickup element 8 on the second lens side is driven with a horizontal reference pulse HD2 with phase leading by (t) than the pulse HD1 and a vertical reference pulse VD2 with the similar phase as that of the pulse VD1 in a vertical direction. In such a way. an image on the second lens side goes to the one whose position in a horizontal direction is shifted against the image on the first lens side by leading the phase, which forms the image in which the optical axis is shifted electrically. Thereby, it is possible to perform the screen synthesis in a form that each object image can be observed simultaneously preventing the object image on one side from being hidden by synthesizing the image on the first lens side with the one on the second lens side whose optical axis is shifted.

Title: Program linking mechanism
Inventor: RICHIYAADO IIUIN BAAMU
IPC: G06F21/12
Filed: 1988-12-20
Abstract: PURPOSE: To individually control the capability of a user and the acknowledgement right to access a space by providing an access register which includes an access list entry token and operating the token. CONSTITUTION: The token included in the access register 22 specifies a space indirectly, so a nonprivileged instruction or subroutine can save and use the contents of the register 22 for another purpose and restores the contents. Therefore, the control and acknowledgement right of the address space can be corrected by operating the token. Further, the definitions of the address space of a system are given from a 2nd table and central control is therefore enabled. Many users have access lists and are then able to access the address space, and >=2 entries can indicate the same 2nd entry. Consequently, the capability of a user and the acknowledgement right to address the space can separately be controlled.

Title: Cleaning device for photosensitive body surface
Inventor: KOISO JUNICHI
IPC: G03G21/10
Filed: 1987-12-17
Abstract: PURPOSE:To improve talc removing ability by forming a polishing pad in a section of rectangular shape, holding two facing surfaces and pressurizing them on the surface of a photosensitive body. CONSTITUTION:The polishing pad 23, which is slidably contacted with the surface of the photosensitive drum 10 and can polish the surface by trace quantity, is formed in a section of rectangular shape.

Title: Method for displaying target for sight recovery training
Inventor: SATO TAMIJI
IPC: A61H5/00
Filed: 1987-12-17
Abstract: PURPOSE:To always perform sight recovery training under an accurate eye examination by preventing the memorizing of each target of a display pattern, by instantaneously altering the direction of the target of the display pattern at random after displaying the same. CONSTITUTION:The breaks of the targets due to Landolt rings of each display pattern are altered by 45 deg. in eight directions. The display time of each display pattern and the altering timing of the displayed sights are preliminarily programmed and the program is inputted to a personal computer by a floppy disk and the answer of each of the targets of each display pattern is performed by operating a keyboard. Respective keys are allowed to relate to the directions of the breaks of Landolt rings and the key of the figure corresponding to each of the directions of the breaks is operated to perform an answer. The directions of the sights of the display pattern are instantaneously altered at random so as to be incapable of memorizing the targets during an eye examination and, even if the direction of each target before alteration is memorized, an accurate answer can not be performed so far as the direction of the target after alteration is confirmed. Since the right answer of the target by memorizing is prevented, training can be always performed under an accurate eye examination.

Abstract: PURPOSE:To obtain a reproduced picture whose quality is high by a simple circuit by detecting the matching of a writing address with a reading address by using a clock pulse for a line address stepping, and operating the thinning-out and double reading of data based on it. CONSTITUTION:A frequency-dividing circuit 20 frequency-divides a clock pulse Rc' from a clock pulse generating circuit 19 for a pseudo reading line address strand obtains 1/2, 1/4, and 1/8 frequency-division signals R2', R4', and R8'. And also, the frequency-dividing circuit 20 supplies the frequency-division signal R2' to a latch circuit 8, obtains an opposite signal R2i, and supplies it to a latch circuit 9. At that time, a detection signal Rp is detected when the cycle tauw' of a clock pulse Wc and the cycle tauW of a clock pulse Rc are at a prescribed rate. And also, the clock pulse for the pseudo reading line address stepping which is compressed for a drum dimension rate is used. Then, at the time of reproduction by a rotary magnetic head whose drum dimension is larger than at the time of reading, the correct thinning-out and double writing can be attained regardless of a tape traveling speed. Thus, the picture data whose quality is high can be obtained.
