Title: Binary image encoding device
Inventor: YOSHIMOTO MASAHIKO
IPC: H04N1/41
Filed: 1986-04-08
Abstract: PURPOSE:To make it possible to encode binary images efficiently by dividing binary image information to unit of specified number for each scanning line and encoding binary image information in unit of specified number basing of probability of occurrence of unit of specified number. CONSTITUTION: Histogram preparing sections 15 of m units are provided respectively with an accumulating section and an output buffer, makes binary coded signals into blocks every n bits and forms histograms P1 by patterns. A demultiplexer 18 takes in histograms obtained by lines simultaneously, and outputs data 8 that indicates probability of occurrence of bit patterns included in video data for m lines. A Huffman code generating section 17 generates Huffman code data corresponding to the probability of occurrence of each pattern from the value of histogram from the demultiplexer 18 and sends them to an encoding section 19. Thus, highly efficient encoding can be realized irrespective of property of images.

Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To provide a structure capable of realizing short channel of transfer gate, without increasing the impressed voltage within an interline transfer CCD image sensor. SOLUTION: A channel control part 13 with the same conductivity-type as that of an accumulation region 3 and an embedded layer 6 is provided in the semiconductor region of a transfer gate TG controlling the charge reading out from the accumulation region 3 to the embedded layer 6.

Title: Manufacture of laminated plate
Inventor: OSAKA KIYOSHI
IPC: B32B37/06
Filed: 1988-03-31
Abstract: PURPOSE:To obtain a laminated plate having uniform property with reduced dimensional shrinkage and warps, by molding a prepreg by heating and adding pressure to obtain a laminated plate, while dipping said laminated plate under atmospheric pressure in a liquid maintained at a temperature not lower than a glass transition temperature of the resin constituting said laminated plate. CONSTITUTION:A prepreg is molded to be a laminated plate through addition of heat and pressure. The molded laminated plate is then dipped under the atmospheric pressure in a liquid which is maintained at a temperature not lower than Tg of the resin constituting the laminated plate. A heating medium for reheating the laminated plate after molding is not gas, but liquid, because the heat capacity of liquid is remarkably great as compared with that of gas, and also the heat conductivity of liquid is good, enabling heat treatment of the laminated plate in a short time. Moreover, it is easy to maintain the temperature within a bath of the liquid constant, whereby an uneven dimensional shrinkage in an XY plane of the laminated plate after the heat treatment can be restricted small. Since the temperature for reheating the laminated plate is not lower than the Tg, the resin constituting the laminated plate is changed into the rubber-like state by the reheating, thereby removing the warps generated by the molding pressure when the prepreg is molded. Further, the reheating is carried out under the atmospheric pressure, thereby causing no warps to said laminated plate otherwise would be caused, by the addition of pressure.

Abstract: PURPOSE:To make a device correspond to a round bar regardless of the outside diameter thereof and to improve productivity by arranging plural pins which freely moves up and down in a line before and behind a holder, forming a shoe and providing a plate which fixes the pins. CONSTITUTION:A bolt 11 is loosend by pressing the holder 3 in a B direction until a guide pin 8 touches the surface of the round bar 1. Since the plural pins 9 whose bottom end surfaces are a spherical state independently and freely move up and down, they respectively touch the outer circumferential surface of the round bar 1. Next, when the bolt 11 is tightened by making the plate 10 whose bottom side is an inverted V-shape touch to the round bar 1 and preventing the holder 3 from being inclined in a C direction, an ultrasonic wave medium can be held by the pins 9 and the weir 14 made of an elastic body. Thus, the device is made to correspond to the round bar having any kind of round diameter and the inspection of flaw-detection is easily executed.

Title: Method and device for controlling electrically driven injection device
Inventor: OMORI KAZUMITSU
IPC: B29C45/50
Filed: 1993-04-06
Abstract: PURPOSE:To prevent the forward runaway of an injection screw and the silver streak for the retreat of the injection screw due to the defficiency of back pressure at the time of the start of plasticization in an electrically-driven injection device. CONSTITUTION:An injection screw 12 is forwardly and rearwardly driven by a forward and rearward driving servo motor 34 through a ball screw nut 24 and a male screw member 26. The rotary torque of the servo motor 34 is detected by a force sensor 28 and the rotational speed thereof is detected by a rotary encoder 36 and both detected values are fed back. A controller 40 outputs a torque command signal CT simultaneous with the completion of a dwelling stage as the value corresponding to back pressure and outputs a rotational speed command signal CS as a zero speed. The forward and rearward driving servo motor 34 becomes a zero speed state by the rotary torque corresponding to back pressure simultaneously with the completion of the dwelling stage. Since sufficient back pressure is obtained, the retreat of the injection screw due to screwing effect is prevented and no silver streak is generated. Since the injection screw 12 is not forwardly driven, the forward runaway of the screw is not generated.

Title: Input protective circuit for semiconductor device

IPC: H01L27/092
Filed: 1988-03-31
Abstract: PURPOSE:To prevent the appearance of latchups by a method wherein a drain/ well P-N junction or drain/substrate P-N junction is not exposed to a forward bias even upon the application of an excess voltage to the input terminal. CONSTITUTION:A step-up circuit 8 capable of generating a voltage higher than a power source voltage and a negative voltage generating circuit 9 capable of generating a voltage lower than the ground potential are provided. Upon application of a voltage higher than the power source voltage to an input terminal 1, a P-channel transistor Tr4 is turned on, which allows a current to flow to a power source terminal 6, when no excess voltage is supplied to the input 2a of an internal circuit 2. With the back gate of the P-channel transistor Tr4 being biassed at a voltage higher than the power source voltage, the P-N junction between a drain D and well 11 in the P-channel transistor Tr4 is by no means biased in a forward direction. This setup prevents the appearance of latchups.
