Title: Preparation of tapered optical waveguide
Inventor: YAMAMOTO KAZUHISA
IPC: G02B6/122
Filed: 1986-12-23
Abstract: PURPOSE:To easily obtain a uniform tapered optical waveguide having high controllability by permitting the treatment at a temp. near the room temp. by dipping a part of a substrate in a soln. contg. a layer having high refractive index after forming the layer to reduce a part of the film thickness of the layer to a thin thickness. CONSTITUTION:After executing a stage for forming a layer 2 having high refractive index by the exchange of proton for a LiNbxTa1-xO3 substrate 1 (where 0<=x<=1), a stage for reducing the film thickness of the layer having high refractive index partly to a thin film thickness is executed by dissolving a part of the substrate in a liquid for dissolving the high refractive index layer. Namely, a LiNbO3Z plate 1 having the high refractive index layer 2 formed thereon is fixed by a sample holder 3 in such a manner that the first part 6 of the plate is dipped in HF 4 by placing the substrate in a beaker 5. The film thickness of the high refractive index layer 2 on said first part 6 is reduced in the HF 4 at room temp. The thickness of the first part 6 is reduced by dipping the second part 7 slowly in HF 4 thereafter. The second part 7 forms a tapered light introducing part. Thereafter, the LiNbO3Z plate 1 is taken out of HF 4 and washed quickly with water.

Title: Image input device and image pickup print system using the same
Inventor: SOEDA HARUO
IPC: H04N5/235
Filed: 1997-11-10
Abstract: PROBLEM TO BE SOLVED: To speedily and exactly control exposure and white balance when performing image pickup through an image pickup device. SOLUTION: An image pickup chamber 5 is provided on the deep side of an aperture provided on the front face of a casing 2. The respective wall surfaces of the image pickup chamber 5 become gray diffusing and reflecting planes in gray having no wavelength selectivity with the fixed concentration. Inside the image pickup chamber 5, a fluorescent lamp is provided for illuminating an image pickup object. The image pickup is performed by a video camera while making the image pickup chamber 5 empty and turning on the fluorescent lamp. An image pickup signal provided from the video camera is monitored, and the exposure is controlled so that the lightness for one picture can become a proper level.  The exposure control is performed by the control of charge storage time at a CCD image sensor (the control of shutter speed) and the control of a gain value at an auto gain control amplifier for amplifying the image pickup signal. The exposure control is performed at fixed time intervals and when the gain value is stabilized, it is discriminated the quantity of light of the fluorescent lamp is stabilized. Then, the exposure control is stopped, and the shutter speed and gain value at that time point are preserved as reference data.

Title: Selective cvd apparatus
Inventor: TSUTSUMI TOSHIAKI
IPC: H01L21/285
Filed: 1991-11-22
Abstract: PURPOSE:To control formation of a metal film such as tungsten film on a wafer fixing jig and bury a metal element within a wafer having an oxide film with a good selectivity by covering the surface of the wafer fixing jig for supporting and fixing the wafer with a high heat-resistant polymer film. CONSTITUTION:A wafer fixing jig 3 for supporting and fixing a wafer 1 is covered with a heat-resistant polymer film such as a hardened film 9 of silicon ladder polymer. Thereby, the wafer fixing jig 3 covered with the heat-resistant polymer film such as the silicon ladder polymer film 9 does not allow formation of the tungsten core on the silicon ladder polymer film 9 even under the forming condition where selective formation cannot generally been maintained. Therefore, tungsten W is formed at the surface of the wafer fixing jig 3 and formation of tungsten on the silicon oxide film 12 is not longer accelerated. Thereby, a metal film is selectively formed only on the necessary region and generation of a problem such as wire-to-wire short-circuiting can be prevented even when a metal wiring is formed on the oxide film.

Title: Method for synthesizing graphic pattern in copying machine
Inventor: MORIGUCHI MASATAKA
IPC: G03G21/00
Filed: 1987-12-04
Abstract: PURPOSE:To prevent the overlapping of graphic patterns by copying a medium to be copied which is copied first, storing the blank part thereof in a storage device, copying the medium to be copied which is copied next in said blank part and sequentially repeating the above-mentioned operation. CONSTITUTION:As soon as the graphic pattern 101 of the body to be copied is copied as the graphic pattern 501 first, the blank part 701 is stored. A part of the graphic pattern 202 of the medium to be copied is copied as the graphic pattern 502 to be the blank part 801. Next, a part of the graphic pattern 302 of the medium to be copied is copied as the graphic pattern 503 to be the blank part 901. Then a part of the graphic pattern 401 of the medium to be copied is copied as the graphic pattern 504. Thus, the graphic pattern of the medium to be copied is copied by limiting only blank part of a copying medium and the above-mentioned operation is repeated until the blank parts do not exist. Now, the blank part is judged and stored as apart where optical energy reflected from the medium to be copied is equal to a certain reference value or above.

Title: Basic brick
Inventor: HAGIWARA NOBORU
IPC: C21C7/10
Filed: 1997-11-11
Abstract: PROBLEM TO BE SOLVED: To produce the basic brick used by combining with a castable refractory at an immersed pipe part, etc., of an RH degassing device. SOLUTION: A magnesia source or/and spinel source having 0.1-1 wt.% B2 O3 content is used as the source of the basic brick. In the magnesia source and spinel starting source, a slaking is hardly caused since an active point of these sources are inactivated with a low melting compd. of MgO and B2 O3 by increasing the B2 O3 content in the source. Moreover, even when the basic brick is produced by using the sources, a resistance to the slaking is maintained. Therefore, the basic refractory brick is improved in service property since the structure deterioration due to the slaking and the formation of the cracking due to expansion are reduced since a resistance to the slaking is improved.
