Title: Manufacture of ink jet recording head and ink jet recording head
Inventor: KOSHIKAWA HIROSHI
IPC: B29C65/08
Filed: 1996-06-26
Abstract: PROBLEM TO BE SOLVED: To junction a substrate with a grooved top plate with higher accuracy and also at high yield to manufacture an ink jet recording head by junctioning the substrate with the grooved top plate by welding, using the horizontal oscillation of ultrasonic wave in parallel with an adhesive face perpendicular to the direction in which the top plate is pressed to the substrate. SOLUTION: After aligning a substrate 5 and a grooved top plate 6 in such a manner that a groove wall 9 averts a heater, an ultrasonic horn 4 descends to hold the grooved top plate 6 and an ultrasonic wave is oscillated when the holding pressure reaches an appropriate level. In this case, the ultrasonic horn 4 oscillates in a vertical direction with the pressure, that is, in parallel with a face on which the substrate 5 is bonded to the top plate 6. The substrate 5 and a wire bonding are free from damage on account of the horizontal oscillation, so that the groove wall 9 does not collapse and therefore, the welding of the substrate 5 with the top plate 6 is possible. Further, a violent frictional heat is generated between the groove wall 9 and a resin layer on the substrate 5 due to the horizontal oscillation at high frequency.  Consequently, the resin is mutually melted and concurrently mixed together and thus both substrate 5 and top plate 6 are welded. The frequency of the ultrasonic wave is preferably 20kHz or higher.

Title: Sheet delivery mechanism
Inventor: WATANABE TETSUO
IPC: B65H29/20
Filed: 1996-06-25
Abstract: PROBLEM TO BE SOLVED: To provide a sheet delivery mechanism hard to cause deterioration of quality of a picture image printed on a sheet. SOLUTION: A sheet 6 is delivered in an A direction and detected by a transmission type sensor 14, and a cam driving motor 23 for a pinch roller is rotated. Thereby, a cam 19 is rotated, vertical motion by this rotation is transmitted to a front side pinch roller 8 through a pressure spring 26, and pressurization is carried out. After the sheet 6 passes the transmission type sensor 15, the sheet 6 advances to an imaging starting position, a thermal head 27 is pressurized and imaging is started. When a sheet head end 6a is detected by the transmission type sensor 16, pressurization of a rear side pinch roller 11 is carried out as pressurization of the front side pinch roller 8.  Though the sheet 6 is provided with moving force by the front and rear side driving rollers 7, 10 in this state, pressurization of the front side pinch roller 8 is released by rotating the cam driving motor 23 for the front side pinch roller simultaneously when a sheet rear end 6b passes the transmission type sensor 14.

IPC: H01L21/302
Filed: 1992-06-22
Abstract: PURPOSE:To prevent an oxide film from thinning at an edge part of a semiconductor thin film pattern when the oxide film is formed on a surface of the semiconductor thin film pattern by thermal oxidation. CONSTITUTION:After a photoresist pattern 13 having a smooth edge part is formed on a polysilicon film 12, the polysilicon film 12 is etched under almost the same conditions of etching rate at the photoresist pattern 13 and the polysilicon film 12.

Title: Image pickup device
Inventor: YAMADA EIJI
IPC: H04N19/60
Filed: 1996-07-16
Abstract: PROBLEM TO BE SOLVED: To compress an image signal through a method of reducing the degradation of decoded image and improving compressibility. SOLUTION: An optical system 43 and an image pickup mechanism 44 pick up the image of image light through oblique uniaxial image shift and output 1st and 2nd source image signals. At an image compressing circuit 59, first of all, a reference image signal is generated by synthesizing the source image signals. Next, a compressed image signal is generated by executing orthogonal transforming processing, quantizing processing and entropy encoding processing to the reference image signal and recorded in a recording medium 60. The number of picture elements in the reference image is half of the number of picture elements in an output image, and these picture elements are arranged in zigzag form. Therefore, the data amount of compressed image signals is less than the data amount of signals with the output image signal subjected to image compression at the same compressibility.  Besides, concerning the image of the output image signal reproduced from the compressed image signal, the degradation of horizontal and vertical direction resolution is reduced and the lower of picture quality of a whole image is suppressed.

IPC: B01D21/02
Filed: 1997-07-11
Abstract: PROBLEM TO BE SOLVED: To enhance the effects of mixing a fine particle suspension water with powder and the reaction efficiency of flocculation reaction in a reaction tank by causing the fine particle suspension water and the powder to be mixed rapidly and instantaneously in a short pipe and guiding the mixture into the reaction tank after causing its direction reaction. SOLUTION: Powder conveyed with a compressed air from a device A for supplying a fixed amount of powder is forcefully introduced into a short pipe 24 from a powder introduction aperture 26A through a capillary 18 in a reaction tank 3. Further, a fine particle suspension water stored in a drum is simultaneously supplied into the reaction tank 3 through a bellows pipe 11 and a suspension water introduction aperture 25A by the action of a suction pump 10. Thus the powder and the fine particle suspension water are instantaneously brought into a chemical reaction directly while both powder and fine particle are mixed rapidly by a first rotating stirring machine 36, and run into an umbrella-like baffle 30 arranged near the bottom part of the reaction tank 3 at a high speed.  Consequently, the instantaneous mixing of the powder and the fine particle suspension water prompts a hydration reaction. In addition, even after the collision of the mixture with the baffle 30, it is slowly stirred by a second stirring machine 29 at a low speed.
