Title: Manufacture of semiconductor integrated circuit
Inventor: TANABE YOSHIKAZU
IPC: H01L21/265
Filed: 1997-09-19
Abstract: PROBLEM TO BE SOLVED: To provide a method for doping impurities by which an impurities doped layer can be formed on a semiconductor substrate at a shallow depth. SOLUTION: Boron ions or molecular ions containing boron are implanted in a shallow area (100 nm or less) of a semiconductor substrate. The semiconductor substrate is then dry oxidized (at about 600-700 deg.C) to form an oxide silicon film on the surface of the semiconductor substrate for preventing outer diffusion. Then the semiconductor substrate is annealed (at about 800-1100 deg.C and in 1-300 seconds) in an atmosphere of inert gas and is dry oxidized at a high temperature and in a short time (800-1000 deg.C and 100-600 seconds). Also, oxygen gas containing water vapor produced from hydrogen and oxygen by a catalytic action is supplied on the major surface of the semiconductor substrate heated to a specified temperature and in its proximity to carry out dry oxidation.

Title: Grain dryer
Inventor: YAMAMOTO SOICHI
IPC: F26B17/14
Filed: 1989-09-29
Abstract: PURPOSE:To shorten the time required for discharging stored grain, by controlling a motor so as to either render the period of reciprocative rotation of a delivering part shorter than that where the flow rate of grain is not less than a predetermined value or increase the rotating speed, upon detection of a grain flow rate below the predetermined value by a grain-detecting means. CONSTITUTION:As a discharging process proceeds, the amount of grain in a grain tank 12 is decreased, and the weight of the grain loaded on a shutter drum 30 is also decreased. Therefore, the amount of the grain contained and discharged through one period of reciprocative rotation of the drum 30 is also reduced, and a limit switch is turned OFF. According to this, a stop time control is carried out to shorten a stop time so that the limit switch is turned ON. The period of rotation of a motor is shortened so that the flow rate of the grain in a grain guide passage 52 will be brought to or above a predetermined value. As a result, an idle time in one period of the reciprocative rotation of the shutter drum 30 during the grain-discharging process is restrained from being increased, and the time required for discharging the grain is shortened.

Abstract: PURPOSE:To lower the deposited amount of Ca ion, etc., and to eliminate the need for cleaning the surface of an electrode by changing over connection of a DC power source and the electrode so that the direction of current allowed to flow between a pair of electrodes is changed over. CONSTITUTION:In the conversion circuit 14 of a detecting circuit 10 for liquid surface, when a signal sent from a terminal 14A is regulated to a low level and a signal sent from a terminal 14B is regulated to a high level, the signals of the low level are inputted to the transistors (Tr) 18A, 18B and the signals of the high level are inputted to the Trs 18C, 18D. Therefore the Trs 18A, 18D are turned on and a closed circuit is formed via a DC power source, the Tr 18A, a protective resistance 22, the electrodes 26A, 26B, the Tr 18D and the earth. Voltage is impressed between the electrodes 26A, 26B to the direction shown in an arrow A. Further when the signal sent from the terminal 14A is regulated to the high level and the signal sent from the terminal 14B is regulated to the low level, voltage is impressed between the electrodes to the direction shown in an arrow B. In such a way, positive and negative voltage is alternately impressed at the prescribed interval. Therefore amount of electricity allowed to flow between both electrodes is made equal and Ca ion is not deposited on the electrodes.

Title: Thermal recording material
Inventor: KIYOHARA TADASHI
IPC: B41M5/337
Filed: 1984-12-04
Abstract: PURPOSE:To improve the durability and fasteness to light, heat resistance of thermal recording material by conaining pigments or dyes having photoabsorption in a specific range of light wavelengths into a heat sensitive layer and/or a heat sensitive film layer. CONSTITUTION:Pigments or dyes having photoabsorption in the range of light wavelengths 400-600nm on a heat sensitive layer and/or a coated layer containing an acid substance which colors leuco dye when heated are provided as additives to leuco dye. This improves the fastness to light remarkably. The acceptable pigments or dyes should have high photoabsorption within the range of light wavelengths 400-600nm. In addition, they are allowed to have photoabsorption of sch light wavlengths and those other than the former. When the fastness to light is enhanced, the introduction of the above-mentioned materials into the protection layer instead of the heat sensitive layer is more effective. If they are introduced into the scattering system, their particle diameter should preferably be smaller. Further, the simultaneous use of ultraviolet ray absorbent or antioxidant as a photo-stabilizer with the pigment or dye used will contritube toward an improvement of the fastness to light.

Abstract: PURPOSE:To easily peel an ice lump from a second icemaking room in the case of ice removing, to reduce water consumption at the time of ice removing and to improve icemaking capacity by composing at least the surface of the room of a substance easily peeled from the lump. CONSTITUTION:A second icemaking room 12 is formed as a block of a thermal conductive metal material such as aluminum, and a film 35 of predetermined thickness is formed on the surface. As the film 35, fluorine resin, polypropylene, polyacetal, etc., are, for example, desirably used. Since the film 35 has properties to easily peel an ice lump, it prevents ice from rigidly freezing to the inner surface of a second icemaking small room 15 at the time of icemaking, thereby eliminating application of a load to the room 12 at the time of inclining and opening the room 12.
