IPC: C23C16/20
Filed: 1987-05-22
Abstract: PURPOSE:To form a thin film having excellent uniformity on a substrate with a plasma CVD device by providing an electron introducing electrode for supplying electrons into plasma in addition to a discharge electrode for forming plasma. CONSTITUTION:After the inside of the vacuum chamber 1 of the plasma CVD device is evacuated to a reduced pressure from a discharge port 2, a reactive gas such as trimethyl aluminum is introduced from gas ejection ports 5 provided on the discharge electrode 4 into the vessel and a high-frequency voltage is impressed from a high-frequency power supply 11 on the electrode 4 to generate the discharge. The gaseous plasma is generated by this discharge to form the thin film of Al on the surface of the substrate 10. The electron introducing electrode 12 made of Al is disposed between this electrode 4 and the substrate 10 and a DC voltage or high-frequency voltage is impressed thereon, by which electrons are freshly supplied into the plasma and the reactive gas is excited by these electrons. The reaction is eventually accelerated and the thin Al film having the excellent uniformity is eventually formed at a high speed on the substrate 10.

Inventor: NOUSO SHIGEYUKI
IPC: B03C3/01
Filed: 1980-09-09
Abstract: PURPOSE:To reduce the size of a titled device and obtain stable dust collection efficiency by converting part of the concd. gaseous SO2 obtained by a desulfurizing device connected to the downstream duct of an electrostatic dust precipitator, and injecting the same to the upper stream of the upper stream duct of said precipitator. CONSTITUTION:The waste gas produced in a boiler 1 passes through a denitrating device 4 and an air preheater 5, and enters an electrostatic dust precipitator 6. The concn. of the SO2 in the waste gas of this time is about 910ppm if the sulfur content in coal is 1%, and that of SO3 is about 4ppm. The waste gas past the precisitator 6 and an induced draft fan 7 flows into a desulfurizing device 8, where it is removed of about 95% SO2. After this gas is removed of dust with a bag filter 10, it is  released into the atmosphere through a chimney 2. The SO2 in the device 8 is desorbed by a desober 11 for an adsorbed gaseous SO2, to 10-20wt% concns. This  SO2 is recovered as single substance sulfur by a sulfur recovery device 12.

Abstract: PURPOSE:To eliminate a need of connection layers to reduce the process and to improve the productivity by constituting a substrate of a conductive magnetic material and bringing one end part of a coil layer and a conductive layer, which should be a lead, into contact with the substrate to connect the coil layer and the conductive layer. CONSTITUTION:A substrate 1 consists of a conductive magnetic material, and a coil layer 4 and a lead 3 are formed on the substrate 1 with an insulating layer 2 between them, and respective end parts of the coil layer 4 and the lead 3 are brought into contact with the substrate 1 through holes 2a and 2b formed in an insulating layer 2. Consequently, the substrate 1 is used as the connection part between the coil layer 4 and the lead 3, and it is unnecessary to form a thin film for connection between the coil layer 4 and the lead 3. Thus, the process is reduced and the productivity of a thin film magnetic head is improved.

Abstract: PURPOSE:To obtain the device which has no mechanical linking mechanism and is characterized by few faults, by detecting the position of a float by a pair of a light projecting device and a light receiving device which are provided on the upper part of a housing and a light reflecting surface provided on the upper surface of the float. CONSTITUTION:One end of an optical fiber cable 20 of the light projecting device 13 is coupled with a light source LED. A specified amount of light from the light projecting device 13 is inputted to the reflecting surface 12a of the float 12. Part of the light is received 14 as the reflected light and transduced into an electric signal by a photoelectric transducer O/E which is coupled with the other end of the optical fiber cable 20. When the liquid level i.e. the position of the float 12 is not changed, the magnitude of the electric signal is not changed. When the liquid level L is changed, the magnitude of the electric signal is changed. Therefore, the height of the liquid level, i.e. the amount of fuel in a tank 15 can be computed and displayed from this signal value.

Filed: 1990-05-18
Abstract: PURPOSE:To reduce the load of a storage area by correcting only a changed part or a layer including the changed part when a drawing is changed and providing a history to each layer. CONSTITUTION:When an initial graphic is corrected, only the layer corresponding to the corrected part is plotted and put on an initial screen. Then a 1st history drawing is produced from an image to which the corrected part is stuck. The identification Nos, e.g., 1-1, 1-2, etc., are added to the newly produced layers, and the layers of each history are stored in a drawing file. Thus it is enough just to include only a changed part into a storage area after securing the regenerating performance of the drawing for each layer. Then the part exclusive for the storage area can be minimized.
