Title: Image forming method of film for o.h.p.
Inventor: KUROTORI TSUNEO
IPC: G03G15/20
Filed: 1989-11-30
Abstract: PURPOSE:To form images without generating image flow by uniformly sticking and applying a solvent on the surface of a film before heating and melting of a surface layer. CONSTITUTION:A film which has a porous layer on the surface layer and is melted and made transparent when heated by a heating source is used as the film for overhead projectors. The solvent is uniformly stuck and applied at >=0.032mg/cm<2> on the surface of the film before heating and melting of the surface layer of the film by fixing. Namely, the surface layer of the film is porous and, therefore, even if the solvent is incorporated into the toner image, the solvent is held in the spacings of the ruggedness on the surface layer. The flow of the toner image by the flow of the solvent is obviated in this way and the surface layer is thermally melted and made transparent at the time of fixing, by which the image is formed.

Filed: 1999-10-29
Abstract: PROBLEM TO BE SOLVED: To provide a fuel injector which provides a fuel injection condition matched with an engine operation condition, and improves output of fuel consumption by reducing NOx, black smoke and HC. SOLUTION: A valve member 20 receives force from fuel pressure in a first control chamber 60 and a second control chamber 65 to a nozzle hole closing direction, and receives force from fuel pressure in a fuel passage 55 to a nozzle hole opening direction. A first spring 15 energizes the valve member 20 in the nozzle hole closing direction. When a first control valve 40 is lifted and fuel pressure in the first control chamber 60 is lowered, a needle 21 is separated from a valve seat 12a and fuel is ejected from a nozzle hole 12b.

CONSTITUTION:When a rotary body 5 is rotated, the material to be treated fed into a treatment tank under pressure by a pressure feed means such as a pump is gradually compressed in compression parts 11 and receives shearing force between the rotary body and the inner wall surface 6 of the treatment tank in shearing parts 12 to be ground and released in expanding parts to again receive compression in the compression parts and ground in the shearing parts 13. The material to be treated continuously receives this action to reach an outlet part and is finely pulverized into a desired size and dispersed. By this method, continuous treatment can be carried out and the vapor problem of a solvent can be solved.

As a result, the materials are vaporized, and a thin film consisting of the plural vaporized materials is formed on a substrate. In this case, a permanent magnet or a cored electromagnetic coil is used as the electron beam deflecting magnets 81-84. An annular magnetic circuit is formed by the magnetic fields 91-94 generated from the magnets 81-84. The crucibles 11-14 contg. the materials to be vaporized and the electron beam generating filaments 31-34 are arranged along the magnetic circuit. The electron beam deflecting magnetic fields 91-94 do not interfere with each other, and a thin film having a good thickness distribution can be formed.

Title: Method of correcting warpage of printed circuit board
Inventor: TANAKA YASUNORI
IPC: H05K3/22
Filed: 1987-12-09
Abstract: PURPOSE:To facilitate correction of warpage in a short time and make the correction step a part of a continuous manufacturing process by a method wherein a printed circuit board is heated or heated and cooled while a pressure is applied to the board by using pinch rollers. CONSTITUTION:In order to correct the warpage of a printed circuit board composed of a thermosetting resin laminared board, the board is heated and cooled while a pressure is applied to the board by single or continuous pinch rollers. A temperature not lower than a glass transition temperature(Tg) is recommended as a heating temperature, which is usually 140-170 deg.C. If solder plating is applied to the pattern, a temperature not higher than 180 deg.C is preferred in order not to melt the solder. It is also recommended to provide a cooling zone in which the board is cooled to a room temperature-50 deg.C after heating. For instance, a pressure part with a width of 1m and a length of 5m is provided with 50 rollers with diameters of 90mm. The pressure part is composed of 3m of a heating zone and 2m of a cooling zone. The respective rollers are pressurized by cylinders so as to have the roller pressure of 1kg/cm<2>. In the heating zone, the maximum temperature of the circuit board is set at 160 deg.C. The temperature of the circuit board at the exit of the cooling zone is set at 40 deg.C. The pressure and the feeding speed are set at 10kg/cm<2> and 0.5m/min respectively. For instance, when 200 sheets of 300X300X1.2mm circuit boards with warpage of 1.5-5.0mm are subjected to the warpage correction, the warpage can be suppressed to less than 0.5mm.
