Title: Production of high-purity titanium oxide film
Inventor: SHIODA MASARU
IPC: C01G23/04
Filed: 1986-04-23
Abstract: PURPOSE:To produce an extremely high-purity titanium oxide film, simply by thermal decomposition without requiring a decomposition agent, by sticking a condensed viscous solution of an aqueous solution of titanium or an alkoxytitanium peroxyhydrate onto a solid, drying the resultant solid film and heating the dried film. CONSTITUTION:Although an aqueous solution of titanium peroxyhydrate or aqueous solution of an alkoxytitanium peroxyhydrate or both are metastable at a cold temperature, free hydrogen peroxide is initially decomposed above room temperature to release a large volume of oxygen gas. The titanium peroxyhydrate with a high peroxyhydrate content is simultaneously converted into titanium peroxyhydrate with a low peroxyhydrate content and condensation is then initiated to gradually increase consistency and form a jelly-like substance. The viscous liquid is then applied onto a solid and air-dried at ordinary temperature to form a homogeneous solid coat, which is gradually heated to >=450 deg.C to give an amorphous titanium oxide film. The resultant film becomes a crystalline titanium oxide film by further heating to >=600 deg.C. This method is carried out simply by thermal decomposition without generating impurities from the individual raw material and requiring addition of a decomposing agent. Thereby the contamination by the impurities is avoided to afford the aimed extremely high-purity product.

Filed: 1992-04-14
Abstract: PURPOSE:To quickly and accurately correct the colors by designating the specific color information out of a standard color image and also out of a corrected color image and correcting the color of the corrected color image based on these designated color information. CONSTITUTION:The color areas are previously set for correcting of each of three primary colors, for example, of the color image signals. Then a color correcting area designated by the corrected area on a monitor screen is limited by means of a look-up table LUT obtained under the control corresponding to the three primary colors. That is, an input image (outputted from a reproducing CTR 54) to undergo the color correction and a reference image are displayed on the same monitor 50A. Then the positions of the colors to be corrected are designated through a touch panel 50B respectively. Thus the colors are corrected by a color corrector 52. In such a way, the influence of the color correction never affects the areas except the designated color correcting areas.

Title: Apparatus for producing fish-paste product
Inventor: HOSHINO AKIRA
IPC: A23L17/00
Filed: 1989-04-14
Abstract: PURPOSE:To efficiently produce a fish-paste product of good quality by constructing a cavity from a pair of electrodes and a mold, placing sheet materials composed of moisture-permeable thin films and aluminum between the electrodes and a ground fish meat raw material and simultaneously carrying out forming and heating of the ground fish meat raw material. CONSTITUTION:Sheet materials 13 composed of moisture-permeable thin films and aluminum are placed between electrodes 9 and a mold 5 is sandwiched therebetween. In this state, a pasty ground fish meat raw material (M) is then filled from a nozzle 11 through a material injection hole 7 into a hollow part 6 of the mold 5. At this time, since liquids exuded from the ground fish meat raw material (M) are permeated through the moisture-permeable thin films thereof, the electrodes 9 and the ground fish meat raw material (M) attain an electrically conductive state through the liquids permeated through the aluminum and moisture-permeable thin films. Thereby, if a voltage is applied across the respective electrodes 9 to flow a current through the ground fish meat raw material (M), which is then heated. The current is subsequently stopped to mutually separate and retreat the electrodes 9 and run the sheet materials 13. The sheet materials are subsequently isolated from the mold 5 and peeled from the obtained formed product. Thereby, in this state, the formed product after completing the heating is taken out of the mold 5.

IPC: F02B29/08
Filed: 1985-04-30
Abstract: PURPOSE:To improve intake efficiency throughout a wide range, according to the method wherein an intake valve is shifted by cams for a low speed and a high speed for opening and closing operation, the length of an intake passage is shifted during low speed running or high speed running, and two shifting operation rotation speeds are differed from each other. CONSTITUTION:A cam 13A for a low speed and a cam 13B for a high speed are disposed in juxtaposition on a cam shaft 10, and during low speed operation, an intake valve 3 is operated by a locker arm 15A brought into contact with the cam 13A for a normally low passed.

Title: Plastic lens whose lens interval varies with temperature
Inventor: YAMADA NOBORU
IPC: G02B7/02
Filed: 1981-06-19
Abstract: PURPOSE:To correct a shift in the focal point of a single lens body in case of fluctuations of temperature, by varying the air interval between a main lens body and an adjacent lens according to the difference in coefficient of expansion between a coupling part for a mirror-frame fitted part and the main lens body, and a mirror frame. CONSTITUTION:A plastic-made lens 50 consists of a main body 52, a lens suspending part 53, and a lens stopping part 55, and between the retaining ring 56 and shank part 54 of a mirror frame 51, the stopping part 55 for the lens 50 is fixed. The suspending part 53 is made of plastic similarly to the main body 52 and is of prescribed size in an optical axis direction. The coefficient of linear expansion of the suspending part 53 is greater than that of the metallic mirror frame 51 and when the ambient temperature drops from the normal temperature to lower temperature, contraction is caused to increase the air interval from a left adjacent lens, so that the air interval of the right convex surface side from an adjacent lens decreases. On the other hand, the left air interval is less at high temperature owing to the expansion of the suspending part 53 and the right air interval is greater. Therefore, a shift in focal point in case of fluctuations of  temperature is corrected.

Abstract: PURPOSE:To perform a light modulation only by applying a modulating signal voltage to the metallic gate electrode of a vertical MIS-FET portion by integrating a semiconductor laser portion and the vertical MIS-FET portion on the same semiconductor substrate in vertical direction.
