Title: Vapor phase reaction apparatus
Inventor: OYAMA KATSUMI
IPC: H01L21/205
Filed: 1993-06-02
Abstract: PURPOSE:To prevent an insulating ring, a heater closure, a soaking plate and its insulating cover from being subjected to degradation of ceramic components due to self cleaning by forming the above-mentioned components with an aluminum nitride ceramic material. CONSTITUTION:A soaking plate 22, its perimetric insulating cover 23, an insulating ring 103 supporting a shower electrode 40, and a heater closure 24 in a reaction furnace of a plasma CVD apparatus 1 are composed of an aluminum nitride ceramic material. This material is used in that these components are exposed to a concentration of plasma and that they are most susceptible to the attack of bromic ion radicals. Further, to increase even more the bromic resistance of these components formed with the aluminum nitride ceramic material, a tight layer of AlF3 can be formed on the surface of the aluminum nitride ceramic material. This enables the plasma CVD apparatus to be resistant to strong impacts.

Title: Discharge lamp lighting device
Inventor: KAMEYAMA EIJI
IPC: H05B41/282
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To limit the lamp voltage at the time of starting so as to lower the exhaustion of a lamp and so as to prevent the shortening of lifetime by inputting a detecting signal at a constant voltage, which is higher than the lamp voltage, in place of the lamp voltage detected during the time from a start of a lamp to the time for stabilizing the lamp into a multipier. SOLUTION: A lamp voltage detecting signal, which is taken from a partial pressure point of lamp voltage partial pressure resistors 117, 118, is input to a multiplier 120, and a detecting signal at a constant voltage, which is obtained from a direct constant current source 126, is input to an input terminal of the lamp voltage detecting signal.  During the time, when the lamp voltage is relatively low after a lamp is started, since the detecting signal at a constant voltage higher than the lamp voltage is input from a direct constant current source 126 to the multiplier 120 through a diode 127 in place of the detecting signal of the lamp voltage, a PWM control circuit 124 performs the constant current control to a direct current power supplying unit B, and when the lamp voltage exceeds the preset constant voltage, the lamp voltage detecting signal is input to the multiplier 120 through a diode 125, and the PWM control circuit performs the ordinary constant power control.

Title: Exposure system for master disk
Inventor: KIMURA NOBUO
IPC: G11B7/135
Filed: 1999-06-04
Abstract: PROBLEM TO BE SOLVED: To prevent the misalignment of focuses of a recording laser and a focusing laser by mounting a lens to give an incident angle on an elevating bed which is mounted on a mobile table moving in the radial direction with respect to the master disk plane, which moves in the direction perpendicular to the master disk plane and which holds a recording lens. SOLUTION: An optical system for focusing is mounted on a elevating bed 14. The laser light of a focusing laser 9 passes through a collimator lens 17, polarizing beam splitter 10 and λ/4 plate 11, then enters a convex lens 19 to generate a specified incident angle, is mixed with the recording laser light on a dichroic mirror 22, and enters a recording lens 7 fixed on the bed 14. The laser light of a recording laser 2 passes through the optical system on a fixed table 21 and enters the recording lens. Even when the thickness of the master disk 15 slightly changes and the recording lens 7 is vertically moved by vertically moving the elevating bed 14, the focusing laser 9 also vertically moves linked with the aforementioned movement so that the distance between the recording lens 7 and the focusing laser 9 is always controlled to be constant.

Title: Facsimile equipment
Inventor: MASAI FUMINORI
IPC: H04N1/00
Filed: 1995-06-23
Abstract: PURPOSE:To easily execute maintenance and cleaning, and further to miniaturize the facsimile equipment by separating a reading roller from an image sensor and a recording roller from a recording head through a single opening/closing operation of an opening/closing part. CONSTITUTION:At the time of the maintenance and the cleaning, the opening/ closing part 9 is opened around an opening/closing fulcrum 10 as a center. By this operation, a contact image sensor 1 and a thermosensitive head 3 are moved upward separated from platen rollers 2, 4 while being held by the opening/closing part 9. Accordingly, the contact image sensor 1, the thermosensitive head 3, a first platen roller 2 and a second platen roller 4 are exposed, and the maintenance and the cleaning can be executed easily. Here, since the contact image sensor 1 and the thermosensitive head 3 are held by the same opening/ closing part 9, the fitting space of the fulcrum of the conventional opening/ closing part to hold the thermosensitive head becomes unnecessary, and a space between the first platen roller 2 and the second platen roller 4 can be shortened by this portion, and the equipment can be miniaturized, and a structure is simplified, and the number of parts, etc., can be reduced.

Title: Electromagnetic fuel injection valve
Inventor: OKAMOTO YOSHIO
IPC: F02M51/06
Filed: 1987-06-26
Abstract: PURPOSE:To maintain the operation of an engine to the optimum by integrally forming a valve body with a bar type valve member having a curved surface part opposite to a valve seat on its end and a movable core with the corresponding part on the other side of the curved surface part being projected out of the core. CONSTITUTION:The inclination angle of the valve seat 5 of a nozzle body 2 and the diameter of the curved surface of a valve body 4 are determined so that the sum total of the capacities of a space formed between the valve seat 5 and the curved surface part of the valve body 4 opposite to it and the space of the injection port 6 of the nozzle body 2 may be as small as possible. Thereby, due to the high speed operation of the valve body 4 and stable flow rate control in a high temperature atmosphere, a wide flow rate control can be carried out while further enabling the flow rate control with high accuracy. Also, since the injection pressure of a fuel injected out of the injection port 6 is increased due to a reduced loss in flow while giving a sufficient revolving force, the fuel can be injected and fed with an excellent atomizing characteristic even in a low temperature atmosphere. Accordingly, the operation of an engine can be stabilized while maintaining a high combustion efficiency and further increasing an operating zone.
