Title: Semiconductor device and production process thereof
Inventor: SHINOHARA TOSHIAKI
IPC: H01L29/78
Filed: 1994-07-08
Abstract: PURPOSE:To suppress the gap between a gate and source from being shorted to thereby improve the reliability by forming a source-body contact, using the anisotropic chemical etching in self alignment with an LOCOS oxide film. CONSTITUTION:A p-type base region 2 is formed on the top face of an n-type Si substrate 1 by the injection of B ions and thermal diffusion. On the upper face thereof, a high concn. n-type source region 3 is formed by the injection of P or As ions and thermal diffusion. The surface of deep grooves formed by the trench etching is thermally oxidized to form a gate oxide film 4. A poly-Si or the like is buried in the grooves to form gate electrodes 5. Then, the thermal oxidation is made to form a gate cap film 11. Using this film as a mask, the anisotropic wet etching is applied to parts of the regions 2 and 3, thereby forming triangular contact holes and source electrode 12 thereon and a drain electrode 8 is formed on the lower face of the substrate.

Abstract: PURPOSE:To lower porosity by providing a stage for forming a phosphor consisting of a binder and phosphor and a stage for imposing the phosphor sheet on a base and adhering the sheet onto the base while compressing the sheet at the temp. above the softening temp. of the binder. CONSTITUTION:For example, the phosphor of a tungstate system is used as the phosphor for radiation sensitization and the thermoplastic elastomer having elastic force at ordinary temp. and flowability when heated is used for the binder. The thermoplastic elastomer having about 30 to 200 deg.C softening temp. is preferable. For example, lower alcohol, such as methanol, is used as a solvent for preparing a coating liquid. The coating liquid contg. the phosphor and the binder is applied uniformly on the surface of the tentative base for forming the sheet and thereafter, the coating is dried and is stripped from the tentative base to form the phosphor sheet. The phosphor is placed on the separately prepd. base and is adhered to the base while the sheet is compressed at the temp. above the softening temp. or softening point of the binder. For example, films of plastic materials, such as cellulose acetate, are used as the material of the base.

Title: Multi-pressure type longitudinal natural circulation exhaust heat recovery boiler
Inventor: KIMURA HAJIME
IPC: F22B37/22
Filed: 1999-06-04
Abstract: PROBLEM TO BE SOLVED: To alleviate additional operation and facility for absorbing a change of a steam drum water lever by setting a high pressure drum as low as possible as long as a stable circulating amount is obtained in a steady state. SOLUTION: When steam drums 1, 2 are installed at high positions, a flow of a fluid having water and/or steam is obstructed by bubbles generated in evaporating tubes 3, 9 by a channel resistance or a head pressure when a boiler is started to become a cause for unstability of the flow of the fluid, and a phenomenon such as water level changes of the drums 1, 2 takes place. The high pressure drum 1 is set to a lower height position than the low pressure drum 2 as long as the stable circulation amount is obtained in a steady state to shorten the channel from the high pressure evaporating tube 3 to the high pressure drum 1. Thus, the stable circulation of the fluid can be obtained after the boiler is started, and a water level change when started in the drum 1 due to an unstable state of the fluid can be suppressed.

Title: Semiconductor integrated circuit device
Inventor: OONO KENICHI
IPC: H03K19/018
Filed: 1977-12-30
Abstract: PURPOSE: To arrange the output voltage of each logic circuit and the threshold voltage to a given value, by determining the circuit constant of the logic circuit corresponding to the supplied power supply voltage.  
     CONSTITUTION: In the emitter coupled logic circuit, for example, the threshold voltage is varied with the power supply voltages V cc  and VEE. In a LSI chip, the effect of voltage drop due to the wiring is great and there is a greater difference with the location on the pattern. When the current flowing to the resistors R1, R2 is kept constant and it is varied for the increments ΔR1 and ΔR2 according to ΔV cc and ΔVEE, the threshold value increment ΔVREF in the LSI chip can be made to zero. The pattern having VEE wiring 1 and that having the wiring 3 are laminated via the SiO 2  film, and the resistance value located in mesh in the collective  region 5 of the logic circuit and having the same corrected value in the region is used. The resistance value is dependent on the width of the resistive pattern electrode, distance between electrodes, and the pattern width. With this method, even with fine power supply wire used, the output or threshold voltage of each logic circuit can be made constant.

Title: Coated arc electrode for cast iron
Inventor: USUI AKIHIKO
IPC: B23K35/365
Filed: 1980-11-10
Abstract: PURPOSE: To provide a coated arc electrode for cast iron giving superior weld metal by coating a material contg. specific amts. of carbon and BaCO 3  on the outside circumference of a core contg. a specific amt. of oxygen.  
     CONSTITUTION: A coating material contg. 5W20% carbon and 10W60% BaCO 3  is coated on the outside circumference of a core consisting of pure Ni contg. 10W500ppm oxygen. The core consists essentially of Ni, and the balance substantially Fe. Since the solid solubility of carbon is low and a carburizing phenomenon is hard to occur, it provides high strength of weld metal when used for welding of cast iron. Since a proper amt. of carbon is compounded with the coating material to suppress arc voltage, the penetration of base metal is lessened and the weld metal of superior performance is obtained.
