Title: Plasma cvd device
Inventor: TAI MASAHIKO
IPC: C23C16/509
Filed: 1985-01-30
Abstract: PURPOSE:To obtain a plasma CVD device which stabilizes electric discharge and improves electric power consumption efficiency by exposing the electrode surface which exists on the side opposite from the electrode surface facing a substrate out of the electrode surfaces of high-frequency electrodes to the atm. side. CONSTITUTION:The reactive gas introduced through a gas piping connection port 16 is ejected through the small hole 181 of a gas diffusing fitting 18 and the through-hole 191 of a partition wall 19 into a discharge region from an ejection hole 13 of the upper electrode plate 11. The reactive gas is excited by the high-frequency electric power impressed to the high-frequency electrode 10 and is thus put into the plasma state, by which the thin film is formed on the substrate of the substrate electrode. On the other hand, the lower surface of the electrode plate 12 is provided so as to expose on the atmosphere side and therefore the reactive gas does not flow into the spacing between the electrode plate 12 and the shielding box. The electric discharge is therefore obviated even if the spacing between the plate 12 and the shielding box is taken large. The value of the capacity to be formed between the electrode 10 and the shielding box is thus made small.

Title: Variable color discharge lamp lighting device
Inventor: TAKEUCHI HIROYASU
IPC: H05B41/36
Filed: 1990-01-26
Abstract: PURPOSE:To produce a comfortable atmosphere conforming with the mentality of human beings by providing a control means for varying color temperature level as setting the color temperature high at the time of full lighting of a fluorescent lamp and low at the time of light control. CONSTITUTION:A control means is formed of a volume Vr, a capacitor C3, an astable multivibrator 5, and a monostable multivibrator 6, and it increases the value of the volume Vr to input a signal having a large duty ratio at the time of full lighting, and reduces the value of the volume Vr to input a signal having a small duty ratio at the time of light control. Thus, the output of a fluorescent lamp 1 having a high color temperature is increased at the time of full lighting, so that the total color temperature is also increased. Conversely, as the output of the lamp 1 is reduced at the time of light control, the total color temperature is lowered. Hence, at the time of full lighting a cool feeling can be produced by increasing the color temperature and at the time of light control, a warm feeling can be produced by reducing the color temperature.

Title: Semiconductor device and manufacture thereof
Inventor: AKASHI TAKUO
IPC: H01L23/522
Filed: 1995-02-06
Abstract: PURPOSE: To provide a semiconductor device and a method for the manufacture thereof wherein wiring electrodes of favorable coverage shape are formed in a fine pattern, and thus a higher degree of integration is feasible. CONSTITUTION: A first layer insulating film 5 of TEOS is formed, and a second layer insulating film 6 of BPSG is formed thereon. Thereafter, a resist pattern 8 for a contact hole is formed, and wet etching is performed using hydrofluoric acid diluted with water. Then dry etching is performed to form a contact hole 9. Since the etching rate of TEOS is lower than that of BPSG, increasing wet etching time increases the amount of the second layer insulating film 6 etched while the first layer insulating film 5 is hardly etched. This smooths the cross- sectional shape of the contact hole 9, and prevents short circuits between the contact hole 9 and a gate electrode 3 even if they are very close to each other. Thus a wiring electrode 10 of favorable coverage shape is obtained.

Abstract: PURPOSE:To enable recording of high sensitivity to be performed even for low speed recording, by a method wherein a top part in contact with a thermal transfer material of an electrode needle is so constructed as to be formed of a compound conductor. CONSTITUTION:An electrothermal head 1 has electrode needles 12, 13 buried in an insulating support base material 11, and each of the needles is tipped with an oxide conductor 14. Then, a thermal resistor 21 is heated by flowing of a signal current given between the electrode needles 12, 13 through the thermal resistor 21, and coloring matter of a coloring material layer is transferred to an image receptor 3 to perform recording. Further, recording is performed keeping a relative speed between an electrothermal head and a thermal transfer material.
