Title: Manufacture of device using lithium tetraborate crystal
Inventor: SAITO HISATOSHI
IPC: H01L41/22
Filed: 1986-12-23
Abstract: PURPOSE:To obtain a device in which the damage of a crystal is eliminated, with resulting high performance and resistance to the use of a high frequency, by using alkaline aqueous solution whose pH exceeds 7 at the time of cleaning a device manufactured by using lithium tetraborate crystal. CONSTITUTION:The titled manufacture is based on knowledge that the solvent quantity of a lithium tetraborate crystal substrate is proportional to H<+> ion concentration. Therefore, by using the alkaline aqueous solution whose pH of cleaning solution is larger than that of ultra pure water (pH=7), the damage of lithium tetraborate is reduced compared with an ordinary rinse process. Next, correlation between the solvent quantity of the lithium tetraborate crystal substrate and rinse solution ph is shown is graph, and it is clear from the graph that the solvent quantity is proportional to the rinse pH. Therefore, the damage of the substrate can be reduced by using the alkaline aqueous solution whose pH exceeds 7 in cleaning. Also, 100 or 110 of the crystal faces of the substrate are permitted, and furthermore, it is possible to prevent the defermation of a positive type resist from being generated by specifying the pH in such way.

Title: Out-band interference wave removing device
Inventor: INOUE TAKASHI
IPC: H04B1/10
Filed: 1992-10-21
Abstract: PURPOSE:To prevent the communication of a radio station from being disenabled by an intrusive interference by providing a filter for removing an interference wave component and a changeover switch for inserting this filter between an antenna system and a low-noise amplifier or bypassing the filter. CONSTITUTION:When no interference wave is intruded, the connecting state of a switch 2 that intervals between contact (a) and (b) and between contact (b) and (c) are respectively turned on, and a signal from an antenna 1 is applied to a low noise amplifier 7 through an RF line 6. When the interference wave is intruded, the contact connecting state of the switch 2 that intervals between the contacts (a) and (c) and between the contacts (b) and (d) are respectively switched to ON. Thus, the signal from the antenna 1 passes through an RF line 3, a filter 4 for removing the interference wave component and an RF line 5, passes through the switch 2 again and is applied to the amplifier 7 through the RF line 6. Thus, the interference wave component is sufficiently attenuated by the filter 4, and the signal of a desired communication channel can be stably received in the state of removing the disturbance caused by the interference component by the amplifier 7, a down converter 8 and a demodulator 9.

Title: Optical gyro
Inventor: NUMAI TAKAAKI
IPC: G01C19/72
Filed: 1998-10-27
Abstract: PROBLEM TO BE SOLVED: To eliminate an optical isolator, ensure a sufficient function using only one detector and reduce the size and weight by inclining the normal to the end face of an optical waveguide against the main propagating direction of incoming/outgoing laser light. SOLUTION: A laser light 110 emitted from a semiconductor laser 11 is split through a splitter 21 into two beams entering an optical waveguide 31. When the end face of the optical waveguide 31 inclines against the main incoming/outgoing direction of the laser light 110, the laser light 110 reflected on that end face is radiated from the optical waveguide 31 and not coupled with the waveguide mode in the optical waveguide 31. Consequently, the light circulating clockwise through the optical waveguide 31 is independent of the light circulating counterclockwise. A part of light entering the end face of the optical waveguide 31 is reflected in a direction different from an incidentone.  The light circulated once clockwise through the optical waveguide 31 is superposed on the light circulated once counterclockwise through the splitter 21 to form laser light 210, which enters a photodetector 41.

Title: Electric wire noninsert section judging method for compression type connecting tube
Inventor: YAMAMOTO KENJI
IPC: H01R4/18
Filed: 1990-11-14
Abstract: PURPOSE:To visually judge the insertion state of an electric wire by providing a judging groove in advance on the surface of the compression section of a compression type connecting tube, and judging an electric wire noninsert section and an insert section based on the presence and the change of the shape and width of the judging groove after compression. CONSTITUTION:When an electric wire 4 is inserted to the middle of the electric wire insertion hole 3 of the compression section 6 of a jumper terminal 5 and it is compressed from the outside, the cross section area after compression becomes 95-90% of that before compression, and a judging groove 7 provided in advance along the length direction on the surface of the compression section 6 at an electric wire insert section 8 is made a smooth face by the pressure and disappears. When the judging groove 7a is compressed at an electric wire noninsert section 9, it does not disappear and is left. The insertion state of the electric wire 4 immediately after compression can easily be judged just visually.

IPC: H01T19/00
Filed: 1992-10-20
Abstract: PURPOSE:To easily attain adjustment for proper heights of a wire and a grid with a simple constitution and further, an easy operation. CONSTITUTION:Height adjusting members 7 which are cylindrically formed and constituted so that their shafts 71 are supported by the side walls 31 of end blocks 3 and the adjusting members 7 can be rotated while abutting on a discharge wire 4 are disposed on both end parts of a discharge 1. The shaft 71 provided on the height adjusting member 7 is disposed in a position a little deviated from the center (a) of the height adjusting member 7. When the height adjusting member 7 is rotated centering the shaft 71, a distance between a contact part with the discharge wire 4 on the height adjusting member 7 and the center (a) is changed. Thus, the height of the discharge wire 4, that is, the position of the discharge wire 4 with respect to a photosensitive drum, etc., is changed. Therefore, the height adjusting member 7 is rotated to adjust the height of the discharge wire 4 to the arbitrary one.

IPC: G11C11/401
Filed: 1990-11-13
Abstract: PURPOSE:To enable an optimum system design to be made regardless of access time which is guaranteed by a manufacturer by outputting a timing signal which indicates a timing when this data is output to an outside when reading data. CONSTITUTION:When writing data into a memory cell array 1 through a sense amplifier 1, 1 is written to a bit corresponding to an additional bit memory cell array 8 which is similar to the array 1 of a timing signal generation circuit 7. Then, when the array 1 is read out, a bit data of the array 8 is also read out and 1-level signal A through an I/O buffer circuit 6 turns on a transistor Q1 through a gate G3 and a timing signal anti VD which is synchronous to a timing when a data which is read out of the array 1 is output from the circuit 6. Therefore, use of this timing signal allows an optimum system design to be made regardless of access time which is guaranteed by a manufacturer.

Abstract: PURPOSE:To obtain a strong compression eddy current suitable for an engine by forming a plurality of saw-toothed projecting inclined surfaces 2 in radial form each of which forms a certain angle for a disc in one direction with respect to the circumference of the disc part on the peripheral edge part from the center of the disc part which forms the top edge part of a piston. CONSTITUTION:Four saw-toothed projecting flat inclined surfaces 2 in radial form which form an angle of about 5 deg. for a disc in one direction for the circumference of a disc part are formed on the perpheral edge part from the center part of the disc part which forms the piston top part 3 of a piston 1. When the piston rises in the compression cycle. The gas in a cylinder applies a force in the direction for lowering and turning the piston with respect to the projecting flat inclined surface 2 of the piston. Since the piston 1 is fixed for suppressing revolution by a connecting rod, the compressed gas turns in a cylinder, and forms a compression eddy current. In the spark ignition type engine having a semispherical combustion chamber, generation of kncoking trouble is suppressed, and the compression ratio can be increased by two times in comparison with the conventional type.
