Title: Solid-state image pickup device
Inventor: OZAKI TOSHIBUMI
IPC: H04N5/378
Filed: 1987-05-27
Abstract: PURPOSE:To reduce fixed pattern noises and to attain a high S/N, by using a capacity feedback type amplifier circuit as an amplifier circuit for detecting and amplifying the potential of a vertical signal line and individually reading out output voltages when no signal charge exist and output voltages when signals exist at every line to obtain the difference between the two kinds of output voltages. CONSTITUTION:When a capacity feedback type amplifier is used as an amplifier for detecting and amplifying the potential variation of a vertical signal line, the potential variation of the amplifier output caused by signal charges becomes the variation of feedback capacity only. Therefore, when the area of the feedback capacity is appropriately designed, fixed pattern noises caused by the variation in gain can be reduced to practically insignificant values. Moreover, by individally reading out output voltages when no signal exists and output voltages when signals exist at every line and taking the differences between the two kinds of output voltages by means of a common differential means, real signal components can be obtained regardless of the variation in DC output voltages when no signal exists in each line. Therefore, fixed pattern noises caused by the variation in the offset voltage of the amplifier of each line can be reduced.

Title: Injection mold and its working method
Inventor: TATEISHI KAZUNARI
IPC: B29C45/26
Filed: 1990-05-18
Abstract: PURPOSE:To prevent molten material from leaking from the border between a ring nozzle and an injecting mold by projecting the nozzle-touching surface of a core mold upward by the displacement amount in downward direction toward the nozzle-touching surface of top force. CONSTITUTION:The nozzle-touching surface 11a on the upper end of the annular projection 11 of a core mold 1 is projected upward by the level difference (h) corresponding to the amount of downward displacement of the nozzle-touching surface 11a by the deformation of the core mold 1 when it is received the pressure in the mold due to the injected material toward the nozzle-touching surface 12a on the upper end of the annular projection 12 of the top force 2 which constitutes the outer peripheral edge of the aperture of the upper end of a runner 5. Since said level difference (h) is such a small grade that it may be absorbed by the elastic deformation due to the load of pressure contact with a ring nozzle, the clearance between the ring nozzle and said molds by the pressure in the mold due to the molten material in injection process does not occur.

IPC: G07D1/00
Filed: 1996-05-23
Abstract: PROBLEM TO BE SOLVED: To decrease the number of parts to suppress increase of the torque of a coin catch disk, to prevent the jam of coins even in a discharge mode of thrown-out coins by defining the disk surface side of a coin as the coin discharge direction and pushing up the coins of the downstream side by the coins of the upstream side with the coin discharge direction defined as a vertical direction, to easily prevent the coin catch miss, and then to prevent increase of the torque due to increase of the rotational frequency of the coin catch disk. SOLUTION: The surface 33 of a coin throw-out disk 3 set at the side of a receiving tray 4 is set almost orthogonal to a horizontal plane, and the base side 21 of the disk 3 is also set in the same way as the side 33. The part of the surface of every coin catch hole 32 that is set opposite to the revolving direction of the disk 3 forms a prescribed acute angle against the surface 33. The shape and area of every hole 32 is almost fixed in its diameter direction at each position in the thickness direction of the disk 3. A coin guide path 7 is extended to an upper vertical pint from a coin throw-out port 5. The moving direction of a coin C is bent toward the surface side of the disk 3 at a bent part 7a of the path 7.

Abstract: PURPOSE:To generate turbulent flow of air in a reaction vessel and to efficiently perform reaction of an odorous component and ozone by introducing one part of air into a by-pass channel around the reaction vessel and blowing out it into the reaction vessel through nozzles, provided on the peripheral wall of the reaction vessel. CONSTITUTION:In order to perform deodorization by allowing an odorous compo nent contained in air to react with ozone, one part of air is introduced into a by-pass channel A1 around a reaction vessel 4. It is blown out into the reac tion vessel 4 through nozzles 43 provided to the peripheral wall 42 of the reac tion vessel 4. Thereby turbulent flow of air is generated in the reaction vessel 4. An odorous component contained in the introduced air and ozone generated by an ozonizer 3 can sufficiently be agitated in this reaction vessel 4. As a result, the reaction of both is efficiently performed.

Title: Ink jet printer
Inventor: DEEBITSUDO NIIRANDO DONARUDO
IPC: B41J2/015
Filed: 1981-08-17
Abstract: PURPOSE: To make possible the uniform production of drops of a liqud and the uniformity of the amount of the drops by a method wherein an apparatus for generating drops of a liquid for an ink jet printer consists of a pipe with an opening cut diagonally at one end and a means of displacing the pipe.  
     CONSTITUTION: The base end 133 of a pipe 101 is connected to an ink tank 103, while the other end 131 is cut diagonally, forming an orifice. When a switch 113 of an actuator 151 is actuated, a magnetic field is generated in pole pieces 105, 107, causing the pipe 101 to move toward the pole piece 107. Next, when the switch 11 is released, the magnetic field is cancelled and the pipe 101 swings to hit an anvil 117, allowing the printing liquid to be discharged from the orifice 131. At this time, the tip of the orifice checks the formation of a second tongue portion of drops and lets the drops fall one after the other. In addition, since the inside diameter of a drop generated is about half of the inside diameter of the pipe, the use of a pipe having a larger diameter becomes possible.

Title: Pointer termination part and uninterruptive switching system
Inventor: ARAI SHIGEHIRO
IPC: H04J3/00
Filed: 1999-05-10
Abstract: PROBLEM TO BE SOLVED: To achieve uninterruptive switching by simpler hardware constitution by allowing a readout timing generation part to stop a readout and shift readout timing to a pointer insertion part only for a pulse output section. SOLUTION: A pointer detection part 21 detects a pointer byte of an SDH signal received from an active or standby transmission line, and extracts and passes its value to a frame header generation part 25. The frame header generation part 25 finds the head of a virtual container VC signal from the pointer value received from the pointer detection part 21 and generates and passes a VC frame pulse indicating the head of the VC signal to a delay buffer part 22. A readout timing generation part 26 shifts the readout timing forward or backward by one byte of the VC signal when a write/read phase monitor part 28 makes a stack request for controlling a readout phase so as to increase a write and read phase difference.

Title: Ink jet recorder
Inventor: KOBAYASHI ATSUSHI
IPC: B41J2/175
Filed: 1985-06-14
Abstract: PURPOSE:To prevent the rise of internal pressure of ink path by a method in which ink coming from at least one of an ink outlet and an ink inlet of an ink jet head is melted before discharging ink and then the ink is discharged. CONSTITUTION:Ink in solid state during the starting period is melted in the neighborhood of an outlet 101 by a heating element 102 to put it in a fluidal state. All ink in the flow path and in the supply port are then melted by a heating element 104. In this case, although an expansion of the volume of ink due to the change of phase occurs, the internal pressure of the path 106 is not so mush raised since ink is pushed out of the outlet 101 and no load is imparted to the device. The ink from the outlet 101 is discharged through an ink supply path 107 and the ink path 106 from the ink tank by an operating element 105.
