Title: Method for injection molding amorphous thermoplastic
Inventor: YAMAKI HIROSHI
IPC: B29C45/73
Filed: 1999-08-27
Abstract: PROBLEM TO BE SOLVED: To reduce a viscosity of a molten resin and to enhance its flowability by cooling the molten resin at a glass transition temperature or higher of the surface of the resin which temperature is lowered due to dissolving of a carbon dioxide in a mold cavity in the surface of the resin during injection filling and a surface temperature of the mold lower than the transition temperature at a center of the resin. SOLUTION: When a resin is filled in a mold cavity after a carbon dioxide gas is fully filled in the cavity, the gas is dissolved in a resin surface layer, the dissolved gas is operated as a plasticizer, a glass transition temperature is lowered only at the surface of the resin or the viscosity of the molten resin is lowered. The gas dissolved in the surface layer is diffused in the resin as a time is elapsed, and a glass transition temperature of the surface layer is raised up to that substantially at a center of the resin. If the surface temperature of the mold is lower than the transition temperature of the center of the injected filled molten, the surface layer and the center are solidified within a normal resin cooling time to get a product. As a result, it can allow an upgraded mold surface transferability and high productivity to be compatible by setting a suitable temperature.

Title: Analog/digital converter
Inventor: YOSHIZAWA TOSHIYASU
IPC: H03M1/00
Filed: 1984-11-15
Abstract: PURPOSE:To improve monolithic IC-implementation and to improve practicability by performing digital conversion processing with a small number of components and eliminating the need for a sample holding circuit. CONSTITUTION:Voltages VRT and VRB showing the dynamic range of an analog input signal are applied to both terminals of a serial resistance group 21 and reference voltages V1-V15 obtained by dividing a potential difference (VRT-VRB) equally into 16 vectors are generated at connection points of respec tive resistance elements. Further, the resistance group 21 is sectional into four areas 21a-21d corresponding to the quantization level of high-order two-bit data. One-terminal sides of differential amplifiers 221-223 are connected to connection points of those areas 221-223, i.e. generation points of the reference voltages V4, VS, and V12. When Va<=Vin<V10 where Vin is an analog input signal, output levels of the differential amplifiers 221 and 222 are inverted and comparators 27 and 29 generate '1' level outputs, so '10' is obtained as the high-order two-bit data. The output level of the differential amplifier 361 of the area 2c is inverted and a comparator 42 generates a '1'-level output, so '01' is obtained as low-order two-bit data. Consequently, 4-bit data '1001' is obtained.

Title: Driving method for display element and display device
Inventor: TSUBOYAMA AKIRA
IPC: G02F1/133
Filed: 1995-09-20
Abstract: PURPOSE: To display an image of high picture quality by preventing a flicker from being generated and following up a moving image speed. CONSTITUTION: When a liquid crystal display element 1 is driven, only scanning electrodes C1a, C2a, C3a... corresponding to subordinate pixels which are large in area are scanned vertically and then only scanning electrodes C1b, C2b, C3b... corresponding to pixels which are small in area are scanned vertically. Consequently, a frame frequency does not decrease and a flicker is prevented from being generated. As for how a motion picture display is seen, (a) lines corresponding to the subordinate pixels which are large in area and make a large illuminance contribution are scanned preferentially at 30Hz to eliminate the parting and shift of the display between frames, and consequently the motion picture display becomes smooth, thereby enabling artificial high-speed drawing.

Title: Recovering method for high-value material in treating polyvinyl chloride
Inventor: GIYUNTAA RIIDEINGU
IPC: C10G5/00
Filed: 1994-10-06
Abstract: PURPOSE: To regenerate valuable materials from polyvinyl chloride wastes by heating polyvinyl chloride under a specific condition.  
     CONSTITUTION: Polyvinyl chloride is heated through the below-mentioned process to recover reusable materials. Polyvinyl chloride is introduced into a reactor 1 through a supply line 4 and heated to from 250 to 500°C in the absence of oxygen in the reactor 1 (by a heat flow gas from a burner 2). This results in generation of hydrogen chloride, carbon-containing residues and plasticizer- containing distillates. The carbon-containing residues residing in the reactor 1 is subjected to cooling and other secondary treatments and used as a fuel for the burner 2. Hydrogen chloride and plasticizer-containing distillates are fed into a condenser 7, where the plasticizer-containing distillates are condensed and taken out through a line 10. Meanwhile, the non-condensed hydrogen chloride, the incondensable hydrocarbons and an inert gas are discharged from a waste-gas line 14. A plasticizer-containing condensate is subjected to fractional distillation to recover the plasticizer.

IPC: B29C39/10
Filed: 1986-10-15
Abstract: PURPOSE:To make a hole-filling operation unnecessary and to reduce the total cost of a switch, by bending a terminal in such a way that a convex face is formed in the opposite direction against the press-cut direction, clamping the terminal between a top force and a bottom force and contacting the concave face of the terminal to the receiving face of a cavity under pressure. CONSTITUTION:A terminal 9 of a base plate 6 is press-cut from the convex face side to the concave face side. The base plate 6 is transferred and positioned along the guide of a bottom force 13 in such a way that the convex face of the terminal 9 faces upward, and a top force 12 and the bottom force 13 are clamped. The curved terminal 9 is clamped between flat facing faces of the top and the bottom forces 12 and 13, and the free end 2a of the terminal 9 is contacted under pressure on a receiving face B due to a counterforce. After clamping the mold, a resin 15 is injected and poured in a cavity 11 from a gate 12a, and the resin is applied in the cavity 11 without penetrating between a fixed contact 2a and the receiving face B. The terminal 9 is cut off and bent and a switch case in which a case 1 and a terminal 2 are integrally combined can be thereby obtained. Since no hole communicating to the fixed contact 2a exists on the rear face of the case 1, there is no possibility of contact obstruction due to the penetration of flux.
