Title: Ceramic member and production thereof
Inventor: KASHIWAGI YOSHIYUKI
IPC: C04B41/88
Filed: 1990-08-08
Abstract: PURPOSE:To obtain a ceramics member having a metallic thin film layer with excellent bond strength, not requiring a brazing material in bonding to other structural members by using a plasma flame spray means in a nonoxidizing atmosphere and sticking fast a metal thin film layer consisting essentially of Ti to the surface of ceramics. CONSTITUTION:A metallic thin film layer consisting essentially of Ti is stuck fast to the surface of ceramics by using a plasma flame spray device in a nonoxidizing atmosphere. Consequently, since there is plasma flame spray in a nonoxidizing atmosphere, an unoxidized metallic thin film layer having few voids can be obtained in a state of high bond strength. After the metallic thin film layer is formed, the film is heat-treated in a nonoxidizing atmosphere to further improve bond strength. By bonding the prepared ceramics member to another structural member, a vacuum device, etc., having excellent durability can be inexpensively produced.

Filed: 1987-08-27
Abstract: PURPOSE: To reduce a facility cost by connecting a plurality of small capacity electric boilers for constituting an electric boiler to a starting transformer, thereby deleting a transformer exclusive use for a very large capacity electric boiler. CONSTITUTION: Small capacity electric boilers 31A, 31B for constituting an electric boiler are respectively connected to a plurality of starting transformers 21 installed in a nuclear power station. The boilers 31A, 31B are energized from the transformers 21 to electrically heat feed water from a boiler water supply tank 25 to steam, which is in turn supplied to an equipment 27 to be heated in the station. Condensate condensed by heating the equipment 27 is returned to the tank 25, and again supplied to the boilers 31A, 31B. Accordingly, since the transformers 21 function as transformers for the boilers, a transformer exclusive use for a very large capacity electric boiler can be deleted. As a result, a facility cost can be largely reduced to improve its economy.

Title: Dry etching method
Inventor: SAKOTA YUJI
IPC: C23F4/00
Filed: 1987-08-27
Abstract: PURPOSE:To increase the etching rates of Au, Pt and Ti when a multilayered structure consisting of Au, Pt and Ti layers is etched, by using Ar and Ar+CCl4 as sputtering gases to etch the Au and Pt layers and the Ti layer, respectively. CONSTITUTION:For example, when the flow rates of Ar and CCl4 in a low pressure chamber 1 and high frequency power from a high frequency power source 6 are set at prescribed values and the internal pressure of the chamber 1 is changed, a Ti layer is etched at a much higher etching rate than Au and Pt layers. Accordingly, when the internal pressure of the chamber 1 is set at a prescribed value and a sample 8 is etched, the Ti layer can be removed in a short time by the action of Cl radicals. For example, an Au layer 81 and a Pt layer 82 are etched with a photoresist layer 84 as a mask and Ar as sputtering gas, the reactive gas is changed over to Ar+CCl4 and a Ti layer 83 is etched.

Filed: 1989-08-18
Abstract: PURPOSE:To obtain a large angle of deflection by providing means for generating light deflection within the waveguide plane in an optical waveguide and forming the grating in an output part in such a manner that the period thereof changes continuously to a sectorial shape. CONSTITUTION:The thin-film waveguide 2 is provided on the substrate 1 and one end face 3 thereof is used as an input part. The output part 4 consisting of the grating, the period of which is changed continuously to the sectorial shapes provided at the point of the prescribed distance from the input part. Electrodes 5 for generating surface acoustic waves are provided between the input part and the output part and the light deflection is executed within the waveguide plane to change the progressiing direction of the light in the waveguide. A laser beam is made incident from the end face 3 and propagates in the thin-film waveguide 2. The guided light is deflected by alpha deg. when an electric field is impressed to the electrodes 5 for generating the surface acoustic waves. As a result, the exit light emitted at theta with respect to the perpendicular line from the point B in the absence of the electric field impression is emitted from the point A. The period of the grating at the point A is smaller than the period at the point B and, therefore, the exit light is eventually emitted at thetaA with the perpendicular line and is largely deflected by theta deg..

Abstract: PROBLEM TO BE SOLVED: To improve operability when setting scale factor at the time of copy by simultaneously displaying a regular scale factor and an arbitrary scale factor on the same screen. SOLUTION: When 'A4→A3' is selected on a setting picture St for the regular scale factor by up and down keys Ku and Kd and selective display (underline) is displayed for 'A4→A3', at the same time, the scale factor of 141% corresponding to this selection is numerical displayed in a display picture Sn for the arbitrary scale factor. Thus, after the scale factor is set by the regular scale factor, it can be precisely adjusted by the arbitrary scale factor immediately. When it is desired to a little reduced an image rather than A3 size, for example, operation for setting 140% or 139% while using a ten key Kt can be continuously performed. Besides, when the set scale factor is matched with any regulator scale factor in the display screen Sn for the arbitrary scale factor, the regular scale factor is displayed while being inverted so that the size of copy image can be known.
