Patent JP-2000252202-A (JP)
Title: Manufacture of semiconductor device
Inventor: TONOZUKA HIDEHIKO
IPC: H01L21/027
Filed: 1999-03-03
Abstract: PROBLEM TO BE SOLVED: To improve overlay accuracy of a circuit pattern by sharply reducing friction of a stage drive system generated at acceleration/deceleration of a stage. SOLUTION: When a circuit pattern is directly drawn on a semiconductor wafer 9 with an electron beam lithography equipment, a dummy pattern is also drawn on a scribe area SA of the semiconductor wafer 9. The dummy pattern is a through hole, etc., and drawn with light exposure of an extent where resist is not exposed. Since the dummy pattern is not patterned in the scribe area SA, high-speed movement of a stage on which the semiconductor wafer 9 is mounted is prevented without having a bad influence upon a semiconductor chip region CR, so that friction of a stage drive part driving the stage is sharply reduced.

Title: Discriminating circuit of switching control signal for sound multiplex broadcasting
Inventor: NEZU SHIYUNICHI
IPC: H04N5/60
Filed: 1981-04-10
Abstract: PURPOSE:To operate a entitled device stably and precisely by dividing an output of a chrominance subcarrier generator so as to be used as a standard signal and comparing the frequency between the standard signal and a switching control signal. CONSTITUTION:A standard signal formed by dividing it from a chrominance subcarrier is inputted to a terminal (a) of a frequency comparator 11. When the frequency of an output of an AM detector 2 is higher than that of the standard signal, the output of a terminal (c) is ''1'' and the output of a terminal (d) is ''0''. When a signal with the frequency lower than that of the standard signal is inputted to a terminal (b), the output of the terminal (c) is ''0'' and the output of the terminal (d) is ''1''. Thus, AND gates 8, 9 generate outputs only at the output of a stereophonic signal and a double signal, enabling to discriminate the switching control signal. Thus, stable and precise operation can be performed and IC configulation can be easily formed, saving electric power.

Abstract: PURPOSE:To eliminate the inconveniences of control due to the height of a mounting position, by fitting a lever in a L-shape in such a way that one mechanical key switch can be controlled from either side of the front or the upper section of a printer. CONSTITUTION:Two sides of a lever 4 in a L-shape are located at the inner side and top position of a main body 3 respectively, and the lower end of the side section of the lever 4 in a L-shape is fitted on a control panel main body 3. As the lever 4 is pushed to the direction of an arrow head A, the lever 4 is deflected, a mechanical key switch 1 is then pushed down. And as the lever 4 is pushed down to the direction of an arrow head B, the lever 4 is deflected, and the mechanical key switch 1 is also pushed down. Thus, the switch can be controlled from wither side of the front or the upper section. By this constitution, the switch can be controlled from the direction which is selected for convenience of control out of two directions depending on the height of a mounting position and other environmental conditions.

Title: Thin-film transistor
Inventor: MATSUDA AKIHISA
IPC: H01L29/786
Filed: 1985-03-19
Abstract: PURPOSE:To form a thin-film transistor, in which an impurity does not diffuse from source-drain, that is, there is no OFF-leakage current, by using a semiconductor film hardly containing the impurity (0.01% or lower) as source-drain electrodes. CONSTITUTION:A source electrode 2, a gate insulating film 3, an amorphous semiconductor film 4 and a two-layer film of a microcrystalline silicon film 5 hardly containing an electrically active impurity such as phosphorus and a metallic electrode 6 in source and drain electrodes are shaped onto an insulating substrate 1. Since the microcrystalline silicon film 5 hardly contains the electrically active impurity such as phosphorus, the impurity does not diffuse into the amorphous semiconductor film 4 even when the temperature of the whole reaches a temperature of 200-300 deg.C on the formation of source-drain, thus also preventing the increase of the OFF-leakage currents of a transistor.

Abstract: PURPOSE:To enable production of a molding having a large thickness and a shape except belt or plate by spraying thermally an amorphous metal in a low-pressure atmosphere in the stage of producing the amorphous metallic molding by a plasma spraying method. CONSTITUTION:For example, a cylindrical cooling base body 25 made of copper is attached to a holder 21 and is rotated at a low speed by a rotating device 23.

Gaseous Ar is supplied therein from a working gas supply device 17 to generate plasma. A plasma jet 29 is injected from the nozzle 8 toward the surface of the base body 25 when a voltage is impressed between the nozzle 8 and the base body 25. The powder of the amorphous metallic raw material is thereupon supplied from a supply hole 9 to the nozzle 8, then the particles are made into micro- liquid drops by the heat of the plasma. The drops laminate and solidify on the surface of the base body 25 so that the cylindrical molding 31 is formed on the surface of the base body 25. The molding 31 is cooled down to about an ordinary temp. when the molding having the required thickness is obtd. The cooled molding is taken out of the chamber 1 and is dipped in a nitric acid, by which the base body 25 is dissolved. The molding 31 is thus obtd.

Abstract: PROBLEM TO BE SOLVED: To provide a flame-resisted fiber suitable for the production of a carbon fiber having high quality, provide a method for converting an acrylic fiber used as a carbon fiber precursor into a flame-resisted fiber in a short time and provide a method for determining the structural nonuniformity effective for the evaluation of flame-resisted fiber. SOLUTION: This flame-resisted fiber for the production of carbon fiber is produced by the heat-treatment of an acrylic fiber and has a density of 1.31-1.40g/cm<3> and a blackness of >=70%. It can be produced by heating an acrylic fiber in air until the density of the fiber reaches a specific level and further performing the heat-treatment in an atmosphere having high oxygen concentration. As an alternative, it can be produced by heat-treating an acrylic fiber in an atmosphere having low oxygen concentration until the density of the fiber reaches a specific level and heat-treating in air and then in an atmosphere having high oxygen concentration.  The structural nonuniformity of the flameresisted fiber is determined by analyzing the image of the cross-section of the fiber taken by an epi-illuminated fluorescent microscope and calculating the ratios of the black part subjected to proceeded oxidation reaction and the light part subjected to insufficient oxidation reaction and emitting fluorescent light to the total cross-sectional area of the fiber.
