Title: Analog switch circuit
Inventor: HAGIWARA SHIRO
IPC: H03K17/687
Filed: 1985-12-25
Abstract: PURPOSE:To reduce the field-through by making the timing when both MOSFETs constituting a CMOS switch is turned off the same in response to the input signal level of the CMOS switch. CONSTITUTION:The titled circuit consists of the CMOS switch SW and N- channel MOSFET Q1 and a P-channel MOSFET Q2 connected in parallel. Switch control timing signals phin, phiP of the CMOS switch SW are crossed at a level nearly the same as an input signal level of the CMOS switch SW in the transition process from the on-state to the off-state of the CMOS switch SW. Thus, the off-timing of a couple of MOSFETs Q1, Q2 constituting the CMOS switch SW is made nearly coincident regardless of the input signal level. The electric charge of opposite polarity injected to the gates of a couple of the MOSFETs Q1, Q2 is made nearly equal to each other and the injected electric charge is almost cancelled to reduce the field-through.

Title: Production of fiber reinforced metallic parts
Inventor: SASAKI MASAYOSHI
IPC: C22C47/00
Filed: 1988-11-17
Abstract: PURPOSE:To prevent the generation of cracks which are the cause for the degradation of strength on the surface of a fiber molding by previously applying a sealing agent onto at least the part, which constitutes the product as it is, of the entire surface of the fiber molding in contact with a mold. CONSTITUTION:Ceramics fibers, such as alumina fibers, are first compressively molded to form the fiber molding 1 having the shape approximate to the shape of a piston at the time of producing, for example, the piston of an internal combustion engine. Curable silicone is then applied by dipping as the sealing agent on the surface, which is in contact with the metallic mold, on the inner side of the fiber molding 1, i.e., the surface in contact with the core mold 3, and thereafter, the silicone is dried to form a thin curable silicone layer 11. This fiber molding q is preheated to the temp. at which the curable silicone is not converted to ceramics. The heated molding is set in the core mold 3 of the metallic mold 2 of a high-pressure casting device. The molten metal of an Mg or Al alloy is immediately poured into the cavity 4 and is solidified while the molten metal is pressurized up to a prescribed pressure by a pressurizing punch 5. The required parts, such as the outer peripheral surface and peak surface, of the resulted molding are machined and piston ring grooves 6, etc., are machined thereto, by which the piston is completed in the final.

Abstract: PROBLEM TO BE SOLVED: To enhance a fire extinguishing capacity reduce damage caused by water and surely detect a fire even during the extinguishing operation by providing a pulse discharge mechanism which performs a concentrated discharge of a specified amount of an extinguishing agent or water instantaneously and repeats it periodically. SOLUTION: When a fire sensor 44 detects fire and outputs a fire detection signal to an anti-disaster control panel 42, the anti-disaster control panel 42 starts a compressor to supply compressed air to an air supply branch pipe 33 and outputs a starting signal to an opening-closing control signal generating section 43. The section 43 outputs an opening-closing control signal to electric valves 37 and 39 simultaneously. The electric valves 37 and 39 repeat a full opening or full closing in the opening of the valve alternately according to the opening control signal and the closing control signal from the section 43.  Therefore, at the time of opening the electric valves 37 and 39, a specified amount of the compressed air in an air tank chamber 34 enters a water tank chamber 36 and a specified amount of water of the chamber 36 is pressurized by the specified amount of air, thus accomplishing concentrated discharge of the water instantaneously from a nozzle part 38.

Filed: 1990-10-30
Abstract: PURPOSE:To perform precise analysis of a minute region more simply by magnifying and displaying the electronic image of the specified region of the surface of a sample at the center of a CRT screen at an arbitrary magnification. CONSTITUTION:Scanning deflecting coils 4a and 4b make an electron beam 2 scan a sample S to be analyzed at a high speed. The image of the sample to be analyzed which is obtained with the radiated electron beam is constantly displayed on a CRT 8. The scanning region of the electron beam is specified on the image of the electron beam on the CRT 8. The deflecting coils 4a and 4b are controlled by a computer 11 based on the specification. The electron beam 2 is made to scan on the specified arbitrary region on the surface of the sample to be analyzed. Thus the arbitrary minute region on the sample to be analyzed can be freely magnified and observed. Since the minute region is scanned with the electron beam 2 and the X-ray spectroscopic measurement is performed in this way, the electron beam 2 is not deviated from the center of the distribution of the elements in the region, and the highly accurate analysis can be performed.
