Title: Image pickup device
Inventor: TAKEMURA HIROO
IPC: H04N9/04
Filed: 1979-05-07
Abstract: PURPOSE: To obtain a high-S/N color signal by subtracting signals of adjacent picture elements of the image pickup element, where color stripe filters are arranged, in the image pickup device using the solid image pickup element.  
     CONSTITUTION: The optical image to be inputted is separated to an optical image of green components and an optical image of magenta light by dichroic prism 2. These green components are converted to an image pickup signal by image pickup element 3. The optical image of magenta light is focused onto image pickup element 4. Color stripe filters are arranged on the surface of element 4, and one of adjacent picture elements detects magenta light components, and the other detects red components. Consequently, when the red signal is eliminated from the magenta signal by demodulators 11 and 12 and substractor 13, a blue signal is obtained. Since the magenta signal and the red signal which include components of the almost same sensitivity irregularity are subtracted, sensitivity irregularity can be reduced to improve S/N.

IPC: H05K1/11
Filed: 1990-03-06
Abstract: PURPOSE:To reduce the external size of a board by a method wherein a plurality of through-hole electrodes connecting several sets of conductor layers formed on both faces of a plurality of semiconductor devices and semiconductor components are formed in one through hole. CONSTITUTION:The shape of a printed wiring board main body 1 is square; the main body has four conductor layers 2a, 2b, 2c, 2d. The conductor layer 2a and the conductor layer 2b become conductive by a through-hole electrode 3b inside a trough hole 3. It can be expected that the space to make the through hole 3 is reduced, that the external size of a printed wiring board is reduced and that the mounting density is enhanced. The shape and the number of the printed wiring board main body 1 and the conductor layers 2a, 2b, 2c, 2d as well as the number of layers are not limited as described above. When other kinds of printed wiring boards having different shapes are designed, the number of conductor layers and the number of layers are changed according to their use.

Title: Heat sink for heating component
Inventor: YASUMA TOMOSADA
IPC: H01L23/36
Filed: 1997-03-11
Abstract: PROBLEM TO BE SOLVED: To prevent the increase in size of a heat sink even if the number of heating components increases and allow the heat sink to be more widely used by forming a flexible holding section between a pair of side boards and holding heating components in the thickness direction by the holding section. SOLUTION: In a heat sink 21, clip sections 29, 31 are formed between a pair of side boards 23 and 25 and thereby housing spaces 37, 39, 41 are formed to hold power transistors 11 in the thickness direction. Owing to this structure, even if the number of the power transistors 11 increases, the size of the heat sink 21 does not increase and thereby a plurality of power transistors 11 can be mounted in a device of a narrow width. Furthermore, a holding face 43 is formed in at least one of the clip sections 29, 31 and so, even such a power transistor 11 that may not be brought into contact with the side boards 23, 25 can have a good radiating property with its rear face being brought into close contact with the holding face 43.  Owing to such a structure of the radiating board, the size of the heat sink does not increase even if the number of heating components increases, and a plurality of heating components can be mounted even in a device of a narrow width.

Title: Centrifugal clutch
Inventor: KINOUCHI SOSUKE
IPC: F16D43/08
Filed: 1986-03-13
Abstract: PURPOSE:To eliminate the need of a clutch clearance adjustment requiring a complicated operation of the seam adjustment by enabling a clutch releasing mechanism to set up such clutch clearances by the use of the pressing force of its spring member, and then justifying the clutch releasing mechanism along direction of the axis. CONSTITUTION:To adjust a clutch clearance W, when a lock nut 43 is loosened, and a shaft 41 is turned clockwise to move a cam nut 42 in the direction B, a clutch releasing mechanism 50 also is moved in the direction B, and the clutch clearance W becomes narrower. In addition, when the clutch clearance W becomes zero, the rotational torque of the shaft 41 is reduced drastically. Subsequently, when the shaft 41 is turned counterclockwise to a fixed number of rotations, the product of the number of rotations and the screw pitch of an adjusting screw 44 is the travel of the clutch releasing mechanism 50, and therefore, the clutch clearance W can be set up with accuracy. And accordingly, even when a clutch plate is worn out, the clearance adjustment can be performed without dismantling the clutch.

IPC: C23F4/00
Filed: 1984-03-26
Abstract: PURPOSE:To realize high-speed plasma-etching for a specimen surface by a method wherein electric force is generated with its lines roughly vertical to a magnetic flux generated by a column-shaped magnetron cathode in a reaction vessel for the creation of a magnetic field in parallel to the axis of the magnetron cathode in the vacancy between the magnetron cathode and a mount for said specimen. CONSTITUTION:An active halogenating gas is introduced into a reaction vessel 10 through a gas controller 13 and the vacuum within is kept at 10-10<-3>Torr. Application of high-frequency electric power across a column-shaped cathode 1 and the activation vessel 10 results in plasma produced around the column- shaped cathode 1. With the lines of electric force, generated between the column- shaped cathode 1 and the plasma, crossing the magnetic flux A in the magnetic field generated by a magnet 3 roughly at a right angle, electrons are driven into a magnetron movement. Under the conditions, a region is created near the cathode 1 wherein plasma density is very high, which allows low-tension of ions in great quantities to flow into the cathode 1. The consequence is a process wherein etching is greatly quickened of a specimen 4 positioned opposite to the side wall of the column-shaped cathode 1.

Title: Method for removing chlorine in alkoxysilane
Inventor: KOMATSU YOSHINORI
IPC: C07F7/04
Filed: 1989-03-09
Abstract: PURPOSE:To inexpensively and efficiently remove chlorine in alkoxysilanes with a convenient method by bringing a basic anion-exchange resin into contact with the chlorine-contg. alkoxysilanes. CONSTITUTION:The chlorine-contg. alkoxysilanes expressed by formula I (R is a 1-8C org. group and n is an integer of 0-3) are brought into contact with a basic anion-exchange resin. The alkoxysilanes are ordinarily passed through a column packed with a basic anion-exchange resin. A fixed-bed system or a moving-bed system is used in the column in this case to remove chlorine, and the desired refined compd. is obtained. The resin is preferably obtained by bonding a quaternary ammonium salt or primary to tertiary amines as an exchange group to a three-dimensionally condensation-polymerized polymer base. By this method, the chlorine content in the alkoxysilanes can be reduced in one stage without a loss of the alkoxysilanes due to their disproportionation.

Title: Movement adaptive signal processor
Inventor: KAWAI KIYOYUKI
IPC: H04N11/14
Filed: 1988-03-10
Abstract: PURPOSE:To transmit additional signals regardless of moving or still pictures by switching adaptively the outputs of moving and still picture processing means in accordance with the detecting output of the return component produced by the movement of the moving picture. CONSTITUTION:A still picture processing means 4a transmits the same information throughout two fields for each frame and a moving picture processing means 7a thins out different fields for each frame. The outputs of both means 4a and 7a are adaptively switched in accordance with the detecting output of the return component produced by the movement of the moving picture. Thus the same information is repetitively transmitted for each frame with a still picture. Therefore, no movement component is included in each frame and the additional signals are easily multiplexed. While a field including no primary signal exists owing to the field thinning with a moving picture and therefore, the additional signals can also be easily multiplexed.
