Title: Manufacture of semiconductor device
Inventor: SATO NOBORU
IPC: H01L21/60
Filed: 1988-11-17
Abstract: PURPOSE:To prevent interlayer insulating films for the lower layers of electrodes from being overetched by a method wherein acidproof insulating films are formed as insulating films for the lower layers of outer connecting metallic electrodes. CONSTITUTION:A P-type well 4 is formed in an N-type semiconductor substrate 1 and after forming a silicon oxide film, a gate silicon oxide film 30 is formed. Next, impurity is implanted into the surface of an N-type semiconductor substrate 1 and the P-type well 4 by ion implantation process. Furthermore, polycrystalline silicon layers 6 are formed to be patterned after phosphorus implantation. First, P-type regions 2 and N-type regions 3 are formed using the polycrystalline silicon layers 6. Secondary, after depositing an interlayer insulating film 3, an acidproof insulating film 9 is deposited. Thirdly, after opening of contact halls, aluminum is deposited and patterned to form outer insulating electrodes 7a and wiring electrodes 7b. An insulating film 10 is deposited and then another acidproof insulating film 11 is deposited thereon. After making openings in the acidproof insulating film 11 on the electrode 7a, the insulating film 10 is removed by wet-etching process using acid base etchant. Through these procedures, even when the insulating film from the lower layers of the outer connecting metallic electrodes is exposed to the atmospheric air on the surface, a semiconductor device of the long time stability and high reliability can be manufactured.

Filed: 1996-11-01
Abstract: PROBLEM TO BE SOLVED: To provide a thick, linear, high-density, high-orientation oxide superconductive bulk body by heating and pressurizing a compression molding. SOLUTION: An wear plate 3 is put on the wide face side of a compression- molded bulk body 1 via a silver sheet 2, for example, so that the wear plate 3 and the bulk body 1 do not react to each other, the bulk body 1 is arranged on a pressing machine 4, and both faces of the bulk plate 1 are pressurized at the prescribed pressure in the high-temperature oxygen atmosphere. The bulk body 1 is set to the semi-fused state, it is easily compressed into a high density, and it is cooled to form a bulk body. This bulk body is pinched and fixed by constraining plates, and it is again heated and baked. Compressive force is applied in the constraint axis direction by the difference in size of phase crystals during this process, the bulk body is oriented so that the constraint axis becomes the C-axis, and the critical current of the superconductive bulk body is improved.  The bulk body is baked then cooled to the prescribed temperature to form an oxide superconductive bulk body unit, and it is pinched and held by long metal plates made of copper, aluminum, or iron to form a large-current bus or the like.

Title: Exhaust structure of ship propulsion unit
Inventor: OKAMOTO YUTAKA
IPC: F02B61/04
Filed: 1993-11-22
Abstract: PURPOSE:To use it jointly even with such an outboard engine as different in output power in common. CONSTITUTION:Two-system exhaust passages 9 and 11 are installed there, and one of at least two types of detachable members opening or closing an opening part is selectively attached to this opening part of the exhaust passage 11 on one side, thereby constituting an exhaust structure of a ship propulsion unit. In the case of a high-powered outboard engine, if the member 12 opening the opening part is attached to the opening part of the exhaust passage 11 on the other, both these passages 9 and 11 are opened together, and thereby large capacity exhaust gas from an engine is exhausted by way of these passages 9 and 11. In addition, in the case of a low-powered outboard engine, if the exhaust passage 11 is closed by the detachable member, relatively small capacity exhaust gas is exhausted out of the exhaust passage 9. Accordingly, the exhaust gas can be exhausted with one side (exhaust passage 9) of these two-system exhaust passages 9 and 11 or both (9 and 11) according to each output power of outboard engines, and thus the end is achieved in this way.

IPC: G11B19/02
Filed: 1999-10-14
Abstract: PROBLEM TO BE SOLVED: To execute an optimum recording operation by detecting information writing situations on an optical information recording medium. SOLUTION: When observations are made on the output waveform from a monitor photodetector 6 in the process of recording to a CD-R (optical information recording medium 4), the output waveform fluctuates when the recording is not made normally while the output waveform is almost rectangular when recording is made normally. Thus, the quality of the recording to the CD-R is grasped by observing the fluctuation of the output waveform from this monitor photodetector 6. The recording operation is controlled optionally in the information recording process by the fluctuation of the output waveform from the monitor photodetector.

Title: Branch saddle
Inventor: TAKAGI NOBUO
IPC: B21D28/28
Filed: 1988-11-21
Abstract: PURPOSE:To make it possible to use even for flammable fluid pipeline as well as to improve the extent of sealability between a saddle body and the existing pipeline by preventing a spark at time of pipeline cutting, and attaching a saddle ring and fireproofing packing after surrounding an interconnecting port of the saddle body so as to surround an outer circumferential surface of the pipeline. CONSTITUTION:A saddle body 2 is surrounded by a clamp 4 and tightly attached to a branch position of an existing pipeline 1 with a bolt 6 without stopping a fluid in the pipeline. Next, when a drilling device 10 is driven by dint of explosive power of powder 15, the pipeline 1 is cut off by a cutting edge 12 of a piston body 13, thus a branch hole 37 is formable. Here this piston 13 forms a hard cost of a nickel alloy on its surface, thereby preventing a spark at time of pipe cutting from occurring, so that it is also applicable even for a flammable fluid pipeline. In addition, a saddle ring and fireproofing packing are attached to a semicylindrical surface-form surrounded surface 3 of the saddle body 13 so as to surround an interconnecting port 8, surrounding an outer circumferential surface of the pipeline 1. Accordingly, since the extent of sealability between the saddle body 2 and the existing pipeline 1 is improvable, even such a fluid as high in permeability for gas or the like can be sealed with certainty.
