Filed: 1996-04-30
Abstract: PROBLEM TO BE SOLVED: To reduce the number of materials for a diaphragm as well as to make it lighter in weight and inexpensive in cost without entailing any damage to the strength and durability of this diaphragm. SOLUTION: A diaphragm 7 of a servo unit consists of an inner circumferential part 7A connected to a valve body, an outer circumferential part 7B being connected to a shell from which extending to the front side while turned up to the rear side, and stuck close to the outer circumferential part of a rear side end face of a power piston, thereby sealing the part, and further plural pieces of beltlike connecting part 7C, extending in the radial direction, connecting these inner and outer circumferential parts 7A and 7B. A part 7D surrounded by both these parts 7A, 7B and two adjacent bandlike connecting part 7C consists in a thin film or through hole.  Accordingly, since the said part 7D is made up into the thin film or through hole, the part is relatively formed into being wall thickness, whereby the number of materials is reduced, abating the cost of production and simultaneously it is can be made to be lighter in weight as compared with the conventional diaphragm.

Title: Engine mounting device
Inventor: TANJI MICHIYASU
IPC: F16M7/00
Filed: 1982-07-30
Abstract: PURPOSE:To achieve the optimal vibration damping effect, by changing the state of coupling depending on the rotational frequency of an engine. CONSTITUTION:A rubber bushing 3 and a mechanical coupling unit 5, which can be controlled by an electrical current, are provided between an engine mounting foot 1 and a chassis 2. The coupling unit 5 is controlled by a regulator 6 depending on the rotational frequency of an engine. When the engine is in a low rotational frequency region, the coupling unit 5 does not function, so that supple engine mounting is performed by only the rubber bushing 3. When the engine is in a high rotational frequency region, the unit 5 functions for coupling, so that high-rigidity engine mounting is performed by not only the bushing 3 but also another rubber bushing 4.

Title: Method for measuring flow trace speed
Inventor: NODA SHIYOUHEI
IPC: G01P5/00
Filed: 1980-09-25
Abstract: PURPOSE:To measure the speed and the direction even in turbulent flow, by suspending fine grains in fluid, varying the intensity of light from a light source during the exposing time of photographing, and discriminating the starting and terminating points of the traces of the suspended fine grains. CONSTITUTION:The light 12 from the light source 11 is transmitted, through a transmitted light intensity modifier 16, expanded to form a plane shape by a lens 13, and illuminates a flowing place to be measured. The fine grains are suspended in the flowing place, and the flow traces of the grains are photographed by a cemera 15. When the light intensity at the vicinity of the end of exposure is increased than that at the start of the exposure by modifying the intensity of the illuminating light in the exposing time of the camera, the flow trace of the terminating point is photographed more brightly than that at the starting point. Thus the speed and the direction can be measured at the same time, and the measurement can be performed even in the turbulent flow.

Title: Memory check device
Inventor: OGAWA HIROSHI
IPC: G06F12/16
Filed: 1986-06-11
Abstract: PURPOSE:To improve the detecting accuracy of the RAM abnormality by writing the numeric values increasing successively to the RAM of each address in the order of addresses and writing the data having bit constitutions inverse to each other to the RAM together with the complement of the data. CONSTITUTION:The data D=1010...10(m bits) is written to an address A0 of a RAM and then the written contents are read out and compared with the data D. Then the error processing is carried out if no coincidence is obtained from said comparison. The RAM address spaces are divided every 2<m> pieces into (alpha+1) blocks in order to write different data to each RAM since data 0-2<m>-1 are obtained with a RAM of (m) bits. Then the sum check is given to each of those divided blocks. For a short-circuiting between RAM the data 0-2<m>-1 are written to each block and the contents of A2<alpham>-1 addresses are added and stored previously in the ROM data from all RAM addresses A0 to be compared with the addition value obtained with a normal RAM 2. Thus a normal state is decided to improve the detecting accuracy of the RAM abnormality.

Abstract: PURPOSE:To secure a stable bonding strength and a high bonding yield by a method wherein a bonding surface with an Al pad in the bump part of a board, which is positioned at the point part of the finger lead of the board and is provided in such a way as to correspond to the position of the Al pad of a semiconductor integrated circuit element, is formed in a creased form or a reticulated form of a specified degree of surface roughness. CONSTITUTION:A bonding surface 7 with an IC chip is formed in a creased form or a reticulated form and the surface roughness degree of the surface 7 is held in 5-15 mum. An Al pad 13 of the chip 12 and the surface 7 of a bump part 6 in a circuit board are aligned to each other in a mutually opposed state. Then, the bump part 6 is pushed by a heater tool from the direction of a finger lead 4 and the surface 7 is pushed to the pad 13 and is pressed and heated. As the surface 7 has a very rough surface roughness degree, the protruding parts of the surface 7 are made to bite into an oxide film formed on the surface of the pad 13 in a wedge form by a pressing force when the surface 7 is superposed on the pad 13 at the time of bonding and moreover, the protruding parts are crushed by the pressing force and are swelled in the direction vertical to the pressing force. Thereby, the oxide film can be destructed very efficiently.

Title: Recording device
Inventor: ABE OONORI
IPC: B41J2/44
Filed: 1978-10-31
Abstract: PURPOSE: To draw a rule at low concentration at high scanning speed and highlight and characters legibly, by constituting to record the underline at the time of scanning return following the character recording and scanning by cathode ray tube.  
     CONSTITUTION: When inputting the recording information, a recording character code is fed to a buffer memory 14, and a line recording information is fed to a buffer memory 15. A character recording picture element signal is formed by a character generator 16, and a decoder 17 compiles vertical line and lateral line picture element signals. The output of an AND gate AN8 delivers a high level signal, when a rule recording command is given, in the scanning return section of electron beam. Since the scanning speed is high in the flyback section of electron beam scanning, this underline is recorded at low concentration. Therefore, the character recording line is not deviated with respect to the rule, so that the characters may be printed legibly, appearing raised in the rule.
