Filed: 1999-11-05
Abstract: PROBLEM TO BE SOLVED: To provide a connection structure which can improve operability. SOLUTION: A sheet material S which is formed by holding an upper side and a lower side of a conductive route M with an insulation sheet N is mounted on an outer surface of a fixed plate A which forms the bottom plate of a resin made case C. At this time, a terminal part 10 of the conductive route M equipped with a bendable elastic strip 12 is inserted into a connection hole 20 which is made on the fixed plate A including a connection end part E for a terminal T. Thus, the elastic strip 12 is bent and deformed in the connection hole 20, at the same time, the terminal part 10 of the conductive route M and the connection end part E of the terminal T are kept in a tightly stuck manner owing to an elastic reaction of the elastic strip 12, therefore, a good connection condition can be kept.  Thus, the connection between the terminal T and the conductive route M can be realized without depending on the conventional welding methods, therefore, operability can be improved.

Title: Plasma arc electrode material
Inventor: USHIO MASAO
IPC: B23K10/00
Filed: 1994-11-24
Abstract: PURPOSE: To provide a plasma arc electrode material suitable for melting and cutting, dissolving, and decomposing at high temperature by producing the material from tantalum carbide or adding one or more substances selected from tantalum, hafnium carbide, and lanthanum boride to tantalum carbide. CONSTITUTION: A main component of an electrode material is tantanum carbide and if necessary hafnium carbide, lanthanum boride, etc., are added to. Since it is possible that necessary density can not be obtained due to some % of free carbon contained in the tantalum carbon, it is preferable to add a slight amount of metal tantalum and then to sinter the resulting body. Since tantanum carbide has inferior oxidation resistance though it has high durability at corrosive atmosphere, it is preferable to add hafnium carbide in 5-30wt.%. On the other hand, lanthanum boride has low work function and excellent electron emitting property. Stable plasma arc discharge can be done by adding lanthanum boride in 0.1-3.0wt.% to a material provided with heat resistance, corrosion resistance, oxidation resistance, etc.

Title: Exhaust gas treating system
Inventor: YASHIMA HIDEO
IPC: B01D53/34
Filed: 1994-12-20
Abstract: PURPOSE: To prevent the interior of a desulfurization absorption column or a chimney from being injured by the heat of exhaust gas in an emergency such as power failure. CONSTITUTION: An air suction duct 15 having a U-shape and filled with water is mounted in a flue 2 between an electrostatic precipitator 5 and an induced draft fan 6. A drain pipe 17 is connected to the bottom of the duct 15 and a solenoid valve 18 is provided in the pipe 17. In a normal operation, since the duct 15 is sealed with water, the outside air is prevented from being drawn into the flue 2 so that the interior of a desulfurization absorption column 7 is controlled at a proper temperature. And in an emergency such as power failure, by opening the solenoid valve 18, water in the duct 15 is discharged through the drain pipe 17, and hence cold outside air can be introduced into the flue 2 through the duct 15, so that temperature of exhaust gas can be lowered.

Title: Reflection-type screen
Inventor: ONO TAKESHI
IPC: G03B21/60
Filed: 1987-12-16
Abstract: PURPOSE:To attain a reflection characteristic identical to a recessed reflecting surface and a thin, flat screen by imparting Fresnel structure to the reflecting surface. CONSTITUTION:After the Fresnel reflecting plate 2 is obtained by molding an acrylate resin 3, etc., the Fresnel reflecting surface is attained by plating aluminum film or coating white or silver paint. The shape of the Fresnel reflecting surface 2 is of saw tooth whose angle gradually increases from the central part to the periphery. Therefore, light 4 projected by a projection type display device (a slide projector is typical) is reflected by the Fresnel reflecting surface 2, and reflected light 5 converges on a focus 6 belonging to the reflecting surface 2. Thus, if a reflection type screen is observed near the focus 6, a bright video, that is, a high efficiency reflected image, can be obtained.
