Title: Low-pressure casting device with inert gas
Inventor: HASHIDA RIYOUZOU
IPC: B22D27/04
Filed: 1982-07-15
Abstract: PURPOSE:To provide a titled casting device which prevents the failure of a thin film in the stage of evacuating the inside of a casting mold chamber to a vacuum, by providing a means for maintaining the pressure in the space formed between the thin film for sealing the inside of the casting mold from the outside air and a pressing metal thereof and the pressure in the casting mold approximately at the same level. CONSTITUTION:A small space 4 is formed between a pressing metal 22 having an improved shape and a movable molding board 1 when said metal is pressed to the lower part of said board. The space 24 and the inside of a casting mold chamber 9 are communicated with each other with pipes 14 and 25, and are connected to a vacuum pump 18 and an inert gas system 19 with valves 16, 17. If the valve 16 is opened and the pump 18 is operated, the inside of the mold 9 and the space 24 are simultaneously evacuated in accordance with their operations. Since no pressure difference is generated between both in this stage, a thin film 11 is not broken and the intended evacuation is completed. As a result, the degree of vacuum in the casting mold chamber is made higher; therefore, the operation for substitution with the inert gas is made shorter in time and this device contributes to the improvement in productivity.

Title: Driving method for active matrix type display device
Inventor: TAKAHARA KAZUHIRO
IPC: G09G3/36
Filed: 1987-05-18
Abstract: PURPOSE:To simplify a driving circuit as compared with a ternary driving circuit and to reduce its cost by setting a threshold voltage at which a switching element turns off to >=2 times as high as a write data voltage and using a binary gate voltage for driving. CONSTITUTION:When the data voltage is in a positive frame, the data voltage Vd and gate voltage VG are applied to select an address and then the switching element 20 turns on to generate 0V as a cell display electrode voltage VS and 5V as a cell terminal voltage VLC, thereby entering a no-address state. Further, the voltage VS is held 0V and the voltage VLC is held at 5V even after the element 20 turns off. Then when the data voltage falls to -5V, a change of the data voltage becomes 10V, then the voltage VS becomes -10V and a gate- source voltage becomes 10V. Then the element 20 uses the threshold voltage which is higher than 10V as 2Vd, so the element stays off at the 10V gate-source voltage without turning on. Thus, the binary gate voltage is used to enable the driving without any trouble.

IPC: B05D1/04
Filed: 1993-05-25
Abstract: PURPOSE:To suppress the generation of a paint edge sump at the time of the emission of paint to the area in the vicinity of the edge part of a surface to be painted to the min. without largely damaging working efficiency and paint deposition efficiency in an electrostatic painting method emitting paint toward the surface to be painted having the edge part while charging the same to apply painting. CONSTITUTION:When a painting gun 12 is moved to the position above the area in the vicinity of the edge part 4a of a surface 4 to be painted, paint is changed over to one with low solvent content. By this constitution, the polarity of paint particles P at the time of the emission of the paint to the area in the vicinity of the edge apart 4a is reduced, that is, electric resistance thereof is increased to make the paint particles hard to charge to reduce the paint deposition amt. to the edge part 4a. Since the paint particles P at the time of the emission of the paint to an area other than the area in the vicinity of the edge part 4a are kept to a state low in electric resistance, sufficiently high paint deposition efficiency is ensured.

Title: Reflowing of metal film
Inventor: MAEDA KEIICHI
IPC: H01L21/3205
Filed: 1997-05-13
Abstract: PROBLEM TO BE SOLVED: To enable reliable reflow of a metal film even when a surface of the metal film is oxidized. SOLUTION: A surface-oxidized metal film 4 of a wafer is reflowed by transporting the wafer into a chamber having a vacuum hydrogen(H2 ) reduction atmosphere 20 and irradiating with a laser beam such as a xenon chloride(XeCl) laser beam 21 while scanning the surface of the metal film 4 by a laser reflow device in the vacuum hydrogen reduction atmosphere. Since the reflow is carried out in the hydrogen reduction atmosphere 20, an oxide film 10 formed on the surface of the metal film 4 can be efficiently reduced. The reduction reaction causes the surface of the metal film 4 to be cleaned without the oxide film 10. Thus, upon the reflow, the surface diffusion of the metal film 4 can be promoted to assist surface migration, enabling good reflow of the film 4.
