Title: Method for removing core
Inventor: NISHIDA MASAFUMI
IPC: B22D29/00
Filed: 1989-07-19
Abstract: PURPOSE:To prevent collapse caused by combustion of organic binder in a core print part by hitting air stream to the core print part in core exhausting combustion gas and cooling at the time of burning the organic binder in the core by supplying O2-containing gas. CONSTITUTION:For example, at the time of manufacturing a cylinder block, after filling up molten metal A into cavity in a metallic mold 9, at the time when solidification of raw material 4 is completed, the air blown into the core under pressurizing from a supplying pipe 5 having a value 8. Then, this air is discharged 6 out of the metallic mold 9 in the arrow mark direction in the figure through the core print part 3 while burning the organic binder in the core body 1 through the core print part 2 in core. In this case, after the lapse of about 2 sec after blowing the air from the supplying pipe 5, by sucking the air from gas exhaust hole 6, the air of the atmosphere is sucked in the arrow mark direction from a supplying hole 7 to cool the core print part 3. By this method, the collapse of core print part is prevented and problem of splash of sand from the gas exhaust hole 6 can be eliminated.

Title: Electromagnetic wave generation apparatus
Inventor: SHIKURA TATSUYUKI
IPC: G01R31/00
Filed: 1998-07-02
Abstract: PROBLEM TO BE SOLVED: To equalize the electric field with respect to transmission direction by setting a parallel conductor connected in the middle of an internal conductor to be parallel to a specific conductor plate of an external conductor, extending straight to the bottom face, and setting a matching resistor between the parallel conductor and the external conductor. SOLUTION: The parallel conductor 7 is connected at a position 9 in the middle of the internal conductor 2, set in parallel to the conductor plate 1C of an external conductor 1 and extended straight towards a conductor plate 1E. A matching resistor 8 is set between the end part of the parallel conductor 7 and the conductor plate 1E. The matching resistor 8 prevents electromagnetic waves from being reflected at the end part of the parallel conductor 7 in conformity with a characteristic impedance of the right end of the parallel conductor 7. Since the gap length between the parallel conductor 7 and conductor plate 1C is constant, an electric field in the gap is equal with respect to a transmission direction of electromagnetic waves. Accordingly, the electromagnetic wave generation apparatus can be made small and the facility cost can be reduced.

Abstract: PURPOSE:To achieve a partial time axis-enlarged recording without damaging continuity of recording by providing an A/D converter, a change rate detecting part to detect the size of a change, a waveform memory to store output data, a recording pattern generating part, and a recording part. CONSTITUTION:When a change rate detecting part 6 detects a sudden change of output data in an A/D converter 2, a control part 5 makes an instruction to a memory control part 7 to take the output data of the converter 2 to a waveform memory 8. A data taking stopping time is controlled taking a timing when a detection signal of the detecting part 6 is added for reference, so desired data can be taken. The memory stored in the memory 8 are read by a recording pattern generating part 3 corresponding to an instruction from the control part 5. The generating part 3 generates a second recording pattern of a second time gauge by enlarging a first time gauge, and outputs it to a recording part 4 with a first recording pattern. The first and second recording patterns are thus recorded simultaneously in a common recording sheet.

Filed: 1992-06-23
Abstract: PURPOSE:To enable an accurate observation of the state of a sample surface in real time by disposing an aperture diaphragm on or near the rear image spatial focal plane of an optical element. CONSTITUTION:An optical system 1 applies light to the surface 2a of a flat sample 2 from its normal direction and focuses reflected light from the sample surface 2a at a rear image spatial focal plane and projects this reflected image onto a screen 4 immediately behind the rear image spatial focal plane and observes the image. During observation of the image, light scattered at the sample surface 2a can be blocked by an aperture diaphragm 3 disposed on the rear image spatial focal plane. Therefore, the sample surface 2a can be observed in focus and most of the scattered light can be eliminated by the aperture diaphragm 3, whereby the visibility of the reflected image is enhanced significantly. Since the overall state of the sample surface 2a is formed in bright and dark patterns behind the blocking portion of the aperture diaphragm 3, the surface state of the sample 2 can be observed at a time.

Filed: 1987-07-29
Abstract: PURPOSE:To shorten the copying digitizing job time by using a digitizing point group data processor to produce the surface data from the NC data obtained based on the point group data and calculating a working bus having an optional cutting direction and an optional pick value. CONSTITUTION:A digitizing point group data processor 6 of a digitizing system outputs the NC data used for the surface working and drives an NC machine tool 9 via a floppy disk 7 or a DNC 8. When a correction is desired to the surface shape after the surface working, the surface shape is corrected by a graphic correction/surface offset part 6d. Then the NC data is outputted for working the corrected surface and the working is given again. Furthermore, it is possible to freely output the working NC data of the remote side or the NC data on the tools of different diameters by means of a male/female inverting function based on the original surface data. As a result, a part having a slow form change of a copying model 10 is copied with a rough pick and only a part having a sudden form change is copied with a fine pick respectively.

Filed: 1990-07-16
Abstract: PURPOSE:To greatly increase the conversion efficiency by making a n-type semiconductor window layer with main composition of activated CdS which is formed due to heat treatment in the CdCl2. CONSTITUTION:A solar cell consists of a n-type semiconductor window layer 2 on a translucent substrate 1, a light-absorbing layer 3 of a P-type semiconductor on it, an electrode 4 for the window layer, and an electrode layer 5 on the light-absorbing layer, all of which are consequently laminated.

Title: Dmos fet
Inventor: KOMACHI TOMONORI
IPC: H01L29/08
Filed: 1996-07-18
Abstract: PROBLEM TO BE SOLVED: To make the capacitance between output terminals of a DMOS FET for use in a semiconductor relay small and to prevent the lowering of the withstand voltage. SOLUTION: A drain is made thinner in order to make the capacitance between terminals of a DMOS FET small. As the drain is made thinner, the withstand voltage is greatly lowered because the radius of curvature of the end part of the drain is made small. This lowering of the withstand voltage is mostly caused by the discharge breakdown in the end part of the drain.  Therefore, the impurity concentration on the side nearer a drain layer of a drift channel layer, only whose end part where the electric field is concentrated is divided into two parts, is made higher than that on the side nearer a P-base layer, and the concentration of the electric field is alleviated in the end part in the extension direction and the outside of the folded part, where the electric field is particularly concentrated, by moving the above-mentioned interface where the impurity concentration is changed, so that the concentration of the electric field is alleviated and the lowering of the withstand voltage is prevented.
