Title: Piston differential-pressure controlling clutch
Inventor: YANAGIHARA SHIGERU
IPC: F15B15/06
Filed: 1984-03-23
Abstract: PURPOSE:To reduce a loss of energy, by providing a guide groove on a cylindrical surface in one of the rotary shafts to fit a roller and transmitting continuous rotation to the other rotary shaft through the differential pressure of a piston, in the case of a piston differential-pressure controlling clutch. CONSTITUTION:A rotary cylindrical surface 4a provides a guide groove 7, which enables a roller 5 to be fitted and displaced in the axial direction, and a piston 8, being able to perform a reciprocating motion in the axial direction outside the cylindrical surface 4a, holds an axis 6 of the roller 5. If an input shaft 1 is rotated, a change of volume, being caused in spaces 14, 15 by reciprocating the piston 8 n-times in a cylinder 10, generates a differential pressure, and if the differential pressure is balanced with propulsive force from the guide groove, rotation of the shaft 1 is transmitted to an output shaft. Consequently, a loss of energy can be reduced by enabling a clutch to play a role as an elastic joint in accordance with springiness of the differential pressure applied to the piston 8 and a curved shape of the guide groove.

Title: Acceleration sensor packaging structure
Inventor: INOUE NORIHIRO
IPC: H05K3/30
Filed: 1997-03-11
Abstract: PROBLEM TO BE SOLVED: To reduce the cost for packaging an acceleration sensor by mounting and fixing adhesively the sensor to a bulking pattern formed such that a position of the sensor except for the inertia part abuts against the mounting position is packaging the acceleration sensor. SOLUTION: An acceleration sensor is packaged and fixed to a ceramic substrate 15 with an adhesive bond on a bulking pattern 20 of the ceramic substrate 15. When the acceleration is applied to the sensor 10 by an impact or the like in the direction G, the inertia part 11 is moved in the opposite direction to G. Since the resistance value of the sensor 10 is varied by the movement, the variation amount is taken out to be converted to the acceleration. The sensor 10 is packaged on the pattern 20 and the inertia part 11 is bulked from the packaging surface of the substrate 15 so that the inertia part 11 can be moved in both directions and the acceleration of the sensor 10 from both direction can be measured. Also, since the pattern 20 blocks the bond 18 from flowing into a slit 12, the inertia part 11 is fixed by the bond 18 to prevent troubles of defective operation. Thus, the bulking parts are not needed to reduce the cost for packaging.

Filed: 1983-03-31
Abstract: PURPOSE:To generate a retrieval table in a short time and to take a pattern analysis by displaying each crystal axis direction which is found by the analysis graphically as coordinate positions, and grasping its relation with a basic crystal axis instinctively. CONSTITUTION:A sphere which has a radius (b) on the basis of the origin 0 of a coordinate system which represents a direction (100) as the x axis, direction (010) as the y axis, and direction (001) as the z axis is considered, and coordinates (x, y, z) of the projection point of each crystal axis (hkl) upon said spherical surface are calculated. While a specific decision on two projection points containing an upper limit angle, e.g. 20 deg. is made, the distance between the two points is calculated and coordinates of the two projection points are stored in a computer as a table at intervals of said distance. Then, three points P1, P2, and P3 are selected from a Kikuchi pattern obtained by an electron microscope and angles of them are measured and converted to calculate distances S1, S2 and S3 on the spherical surface, while are used to retrieve said stored table, assigning the respective points as specific crystal axes.

Title: Magnetic reproducer
Inventor: MORI HIROICHI
IPC: G11B5/008
Filed: 1981-04-14
Abstract: PURPOSE:To reproduce both of magnetic tapes of analog recording and PCM recording, by detecting the presence or absence of a synchronizing signal. CONSTITUTION:A content recorded on a magnetic tape T is reproduced via a magnetic head H1 for analog and a magnetic head H2 for PCM to obtain respective reproducing signals (a) and (b). On the other hand, a switch control circuit CTL receives the output of a demodulation section DEM detecting a synchronizing signal and detects the presence or absnece of the synchronizing signal. When the synchronizing signal exists, a changeover switch SW is controlled in interlocking with a PCM signal to output a PCM reproducing signal (b). When no synchronizing signal exists, the switch SW is controlled to output an analog reproducing signal (a). Thus, reproducion can be made even when the magnetic tape T is recorded with PCM or analog signals.

Title: Ceramic wiring board and its production
Inventor: NAKASU KOICHI
IPC: H05K3/00
Filed: 1997-03-11
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of blister in the Cu plating film on the surface of a ceramic substrate at the time of subjecting the Cu plating film to a heat treatment. SOLUTION: After the surface of the alumina substrate 11 is roughened by etching, a liquid of a catalyst for electroless Cu plating is applied on the surface of the alumina substrate 11. The Cu plating film 12 having a film thickness of 0.5 to 1.5μm is thereafter formed on the surface of the alumina substrate 11. Since the Cu plating film 12 is thin, many pinholes are formed at the Cu plating film 12. The pinholes play the role of allowing the evaporation gases generated on the surface of substrate at the time of the heat treatment of the ensuring stage to escape. The Cu plating film 12 of the alumina substrate 11 is then heat treated in an inert gaseous atmosphere, by which the adhesion strength of the Cu plating film 12 and the alumina substrate 11 is enhanced.  The evaporation gases generated at the time of the heat treatment are allowed to escape outside from the pinholes of the Cu plating film 12 and do not push up the Cu plating film 12.
