Patent JP-H09326480-A (JP)
Title: Solid state image sensor and driving method therefor
Inventor: UENO TAKAHISA
IPC: H04N5/341
Filed: 1996-06-05
Abstract: PROBLEM TO BE SOLVED: To obtain a good image by injecting bias charges into a region for storing charges through photoelectric conversion after reset and then storing signal charges and reading out a pixel signal thereby improving fluctuation in the I/O characteristics of the pixel. SOLUTION: After signal charges are stored (for an interval T1 A) in a first frame, a pixel signal is read out (at a moment of time T1 B) and then the charges stored in a pixel are reset entirely (at a moment of time T1 C). Subsequently, bias charges are injected into the pixel (at a moment of time T1 D) in order to compensate for the fluctuation of potential well thus bringing about a uniform potential state in the breadthwise direction of the gate. A signal representative of the absence of the signal charge in the pixel, i.e., a reference value due to the bias charges, is then read out (at a moment of time T1 E). Thereafter, storage of signal charges in a second frame is started and a similar operation is repeated.  The difference between a pixel signal read out after storing the signal charges and a reference value based on the bias charges of the pixel is taken out as an output signal.

Abstract: PURPOSE:To reduce a cost by a method wherein an air suction pipe is connected to a throttle part formed on the delivery side of a circulating pump to mix air in circulating water, and the circulating water is brought into contact with the vaporizer of a freezing cycle to cool the circulating water. CONSTITUTION:With a motor 25 for driving a circulating pump started, an impeller 24 is rotated to deliver water in a fish preserve 11 to a piping 12b for feed. In this case, in a circulating pump 13, sucked water is pressurized to a value higher than an atmospheric pressure and is delivered with a pressure through a delivery port 23 to an injection pipe 26. Water passing through a throttle part 28 is further accelerated to increase a dynamic pressure component, a static pressure component is reduced by an amount equivalent to the increase and to a value lower than an atmospheric pressure. Air is sucked through an aeration function and mixed as air bubbles in water passing through the injection pipe 26. Water in the fish preserve delivered through an injection hole 27 of the injection pipe 26 to the piping 12b for feed is fed to a cooling later tank 5 of a cooling device 6. The water is brought into contact with a vaporizer 4 of a freezing cycle A for cooling and is returned to the fish preserve 11 through a piping 12c for return. This constitution enables elimination of an air pump and reduction of a cost.

Abstract: PURPOSE:To selectively oxidize a semiconductor substrate without pattern conversion difference by laminating SiO2, Si3N4 on the substrate, selectively oxidizing the superposed polysilicon with the SiO2 and Si3N4 as masks of two layers to form an SiO2 mask and etching and opening the lower layer. CONSTITUTION:SiO2 12, Si3N4 13, polysilicon 14, SiO2 15, Si3N4 are superposed on an Si substrate 1, a resist mask 17 of width W is coated, they are then plasme etched to form a film 16'. Then, a side etching alpha1 is produced. When the polysilicon 14 is converted to SiO2 18 via the mask 16', a bird beak beta1 is produced, and when the films 16, 15, 14' are etched by plasma and NH4F, a hole 19 is formed in size difference gamma1. When it is plasma etched via a mask 18 to form a film 13', a side etching alpha2 is produced, the film 18 is removed with NH4F, a hole is opened at the film 12, thereby forming an SiO2 20. When the films 13', 12 are then etched, the bird beak is retarded from beta2 by gamma2. When the thickness of the film and the wet oxidizing conditions are selected at alpha1=alpha2, beta1=beta2, then because gamma1, gamma2 are minute respectively, and the conversion difference can be entirely set to zero.

Filed: 1984-07-11
Abstract: PURPOSE:To contrive to improve the yield of molding material or of urethane foamed material by a method wherein the heights at both the side parts and the central part of a film gate are made different from each other at or near the opening on cavity side of the film gate in order to mold the steering wheel. CONSTITUTION:A steering wheel core bar is set at the predetermined position of a top force 16a. After that, a mold is closed and urethane foamed material is poured through a gate 18 into a cavity 17 in order to form coating layers 12b and 13b on the outer peripheries of a ring part core bar 12a and spoke part core bars 13a. In that case, because heights h1a at both the side parts are made larger than a height h1b at the central part in an opening 18a, the flow speeds of molding material to be poured in the cavity 17 at both the side parts of the opening are different from that at the central part. As a result, the air at the rugged part 16a of the top force 16, which tends to stagnate, is flowed away being pushed by the molding material, resulting in enabling to mold the titled wheel with no generation of void at the outer periphery of a ring part 12 with no formation of air vent hole at the rugged part.
