Title: Method and device for holding and transporting printed circuit board
Inventor: KONDO KENJI
IPC: H05K13/00
Filed: 1990-10-08
Abstract: PURPOSE:To save the labor for setting the reference level of a holding pawl by pressing a circuit board pressing plate by the recovering force of a compression spring and transporting a printed circuit board while holding the printed circuit board by a press fitting pawl. CONSTITUTION:The base part 27a of the circuit board pressing plate 27 moves and turns from the rear surface 41Ab of a 1st pressing plate guide 41A to the rear surface 44a of a rotary pressing plate 44. The base part 27a of the circuit board pressing plate, then, parts from the rear surface 44a of the rotary pressing plate and moves to the rear surface of the 2nd pressing plate guide. The printed circuit board is imposed on the holding pawl 26 at this time. A chain bode 5 travels further and the base part 27a of the circuit board pressing plate 27 transfers from the rear surface of the 2nd circuit board pressing plate; thereafter, the printed circuit board on the holding pawl 26 is held by the press fitting pawl 28 pressed by the pressing force of the compression spring. The printed circuit board travels and is subjected to a soldering treatment. The press fitting pawl 28 is risen at the point of the 3rd pressing plate guide by which the pressing is released and the printed circuit board is removed.

Abstract: PURPOSE:To execute appropriate close-up photographing by providing a lens holder which can freely move in a direction traversing a photographing optical axis and a guiding plate held so that it can freely slide, and keeping the lens holder and the guiding plate in a specified positional relation with respect to an optical axis direction. CONSTITUTION:By operating a knob 16, the lens holder continues to rotate counterclockwise and the energizing force of a toggle spring 41 acts in a direction where the counterclockwise rotation is promoted from the middle of the rotation of the lens holder. Then, the rotation is stopped in a state where a sector part 30 abuts on a stopper 37 as shown in figure B. At such a time, a macro lens 14 is positioned on the photographing optical axis 13 and a target mark 19 is interposed in a finder 18. In such a state, the lens holder is positioned and fixed between the spring 41 and the stopper 37. The mark 19 is interposed in a specified position departing from the center of the visual field of the finder 18, and the center of a viewing angle at the time of macro photographing is displayed. Therefore, the compensation of parallax is performed by taking the mark 19 as a reference.

Title: Impurity diffusion furnace
Inventor: HARIBUCHI HIDEO
IPC: H01L21/22
Filed: 1993-10-28
Abstract: PURPOSE:To prevent the sealing between members due to the adhesion of an adhesion source by covering the joint between components which are exposed to the inside of a reaction chamber and are extremely in contact with an adhesion rejection plate formed at the components on an impurity source supply side. CONSTITUTION:A reaction pipe 11 is placed at a disk-shaped lid 12 and a cylindrical temperature-preservation cylinder placement stand 12B is formed at the center of the lid 12. Also, an adhesion rejection plate 13A for covering the joint with the temperature-preservation cylinder placement stand 12B with a spacing is formed in an orbit outside the outer-peripheral side surface of a temperature-preservation cylinder 13. Also, an exhaust hole 11B is formed at the lower part of the reaction pipe 11 and a source gas is evacuated. Then, the adhesion rejection plate 13A prevents the source gas from being adhered for the flow of the source gas. Then, since the adhesion rejection plate 13A has a spacing at an area to the joint, the adhesion rejection plate 13A cannot be sealed to the joint, thus reducing the replacement frequency of components and improving production efficiency.

Abstract: PURPOSE:To obtain a capacitance element having a highly reliable thin capacitance insulating film by a method wherein a trench is formed in an Si substrate and an insulating film is built up by epitaxial growth and, after an Si epitaxial film is built up on it, the capacitive insulating film is formed. CONSTITUTION:A trench 1a is formed in an Si substrate and an insulating film 3 is built up by epitaxial growth on the substrate along the trench 1a. After a thin Si epitaxial film 3 is built up on the film 2, impurity such as phosphorus, arsenic or boron is diffused into the film 3 to reduce the resistance of the film 3. Then the film 3 is subjected to thermal oxidation to form a capacitance insulating film 4. Then a polycrystalline silicon film is built up on the film 4 and impurity is diffused to form an upper electrode 5. With this constitution, the influence of unevenness caused by grains is eliminated and the thickness nonuniformity is hardly produced. Therefore, a capacitance element having a highly reliable and uniform thin capacitance insulating film can be formed easily.

Title: Control device for direct injection engine
Inventor: HARADA AKINORI
IPC: F02D41/06
Filed: 1998-09-24
Abstract: PROBLEM TO BE SOLVED: To prevent a starting shortage at an extremely low temperature by controlling a generation time of an initial explosion by cutting an ignition of the cycle number of at least one cycle at the time of cranking of a direct injection in cylinder at the extremely low temperature and supplying a fuel to all cylinders during the ignition cutting. SOLUTION: In the case where an initial explosion is generated in No. 1 cylinder at the time of cranking of an engine 1, since No. 3 cylinder is already at a finishing time of a suction stroke and obtains a sufficient injection quantity, the No. 3 cylinder is normally ignited. However, at the time of an injection period of No. 4 cylinder, since an engine revolution number is increased, the injection period is shortened and an accidental fire may be generated. At the time of a starting at an extremely low temperature, for the time of at least one cycle before a generation of an initial explosion, an ignition is forbidden by an ECU 30 and a fuel injection into each cylinder is only carried out for the time period. After completion of the ignition cut cycle, the fuel injection and the ignition are carried out.  A judgment revolution number for judging a starting mode and a mode after starting is set to approximately 2 times in comparison with a usual case.
