Patent JP-H01214009-A (JP)
Title: Semiconductor chip for integrated circuit
Inventor: MATSUSHITA TADASHI
IPC: H01L21/02
Filed: 1988-02-22
Abstract: PURPOSE:To stabilize an electrical characteristic and to prevent the destruction of an active element and the like formed on an active element formation region by a method wherein the region is formed into a circular shape or a polygonal shape with five sides or more by setting a semiconductor chip as the center. CONSTITUTION:In a semiconductor chip 5 for integrated circuit use, an active element formation region 5a is formed into a circular shape or a polygonal shape with five sides or more by setting the semiconductor chip 5 as the center. For example, while the active element formation region 5a of the semiconductor chip 5 is formed to be circular-shaped, a circuit which is not used during the operation of an integrated circuit or a dummy circuit for process condition confirmation use or for inspection use which is used during the manufacture of the integrated circuit is formed at a peripheral part 5b of the active element formation region 5a. By this setup, a die bonding material 6 creeps to the whole of the lower part of the formation part 5a of an active element which generates heat; the heat generated by the active element formed on the semiconductor chip 5 can be dissipated efficiently.

Title: Clutch adjusting warning method
Inventor: YOSHIMURA HIROSHI
IPC: F16D13/58
Filed: 1985-02-28
Abstract: PURPOSE:To adjust a clutch by a link rod by giving a clutch adjusting warning when the difference of a learning value between the initial clutch connection point and its complete connection point is under a set value. CONSTITUTION:The difference of a learning value between the initial connection point of a clutch and its complete connection point is calculated and compared with a set value. When the learning value is under the set value, a clutch warning counter is added by one point. The counter value is compared with a counter set value and when it becomes over the counter set value, a clutch adjusting warning is given and a signal is flickered. Thus, a driver can be informed of the extent of wear of a clutch.

Title: X-ray photographing device
Inventor: KIKUCHI MINORU
IPC: H05G1/00
Filed: 1989-02-20
Abstract: PURPOSE:To reduce an operating burden by measuring the body thickness of an object analyte with a micro-light-emitting element and micro-light receiving element installed side by side opposed to each other and set X-ray photographing conditions suitable for the body thickness. CONSTITUTION:A line sensor is constituted of a light emitting section 7a which is longer than the body thickness of an object analyte 4, where micro-light- emitting elements 7a1-7an are linearly set side by side and a light receiving section 7b made up of micro-light-receiving element 7b1-7bn set opposed to the light emitting section 7a. Thereby, the body thickness of the inspectee 4 is measured through a computing element 8 according to a signal inputted from the elements 7a and 7b to find photographing conditions of an X-ray source suitable for the inspectee's body thickness. It is possible, therefore, to automatically obtain good X-ray image and reduce an operating burden.
Patent JP-S58156742-A (JP)
Title: Friction damper
Inventor: SAGOTA KATSUAKI
IPC: F16L3/202
Filed: 1982-03-12
Abstract: PURPOSE:To facilitate the setting of spring forces and at the same time prevent springs from being broken by a structure wherein the springs arranged axially for energizing and restoring a damper body and the spring, which elastically couple an inner ring and a damper body holding member in the direction of rotation, are inserted separately. CONSTITUTION:An auxiliary tube 2 relatively goes in and out of a main tube 1 axially and a ball nut 4 rotates a screw rod 3 together with the inner ring 5 in order to rotate the damper body holding member 6 through torsion springs 7 and balls 10. When the relative motion between the main tube 1 and the auxiliary tube 2 becomes abruptly faster, the rotation of the damper body holding member 6 can not follow up to a rotation of the inner ring 5 due to the larger inertia of the member 6, resulting in generating the relative rotation between the ring 5 and the member 6 by compressing the legs of the torsion springs 7 and consequently causing the balls 10 to run up slant faces and an annular friction member 11 to bring into contact with a brake ring 12 in order to realize the locked state. In such a manner as described above, because the torsion springs 7 and compression springs 9 are separately inserted, the setting of the spring forces is facilitated.

Abstract: PURPOSE:To effectively prevent separation of a slider layer by bending the butt end portion of the slider layer towards the interior of a cut-off portion of an adjacent layer, and putting embedded rubber to the bent portion from the outer surface of the dipped slider layer to be vulcanized. CONSTITUTION:Each end surface of a reinforcing canvas layer 13 is separated corresponding to a butt end portion of the length required of the lower slider layer 14, and the end portion of the slider layer 14 is bent toward between the thus separated end surfaces of the reinforcing canvas layer 18.

Title: Superconductive device
Inventor: ARIMA KAZUAKI
IPC: H01L39/14
Filed: 1978-04-06
Abstract: PURPOSE:To prevent both the burning loss of the coil itself at the quenching time and the increment of the container's inner voltage by reducing the resistance value of the protective resistance provided outside the container storing the superconductive coil less sufficiently than the resistance value of the permanent current switch at the off-time. CONSTITUTION:Both superconductive coil 1 and permanent current switch 5 are stored in cryostat 2. When the permanent current operation is started with excitation of coil 1, coil 1 is cut off from the power source via terminal 6 and 6'. But in case coil 1 is quenched under operation of the permanent current, it is detected by quench detector 7. And permanent current switch operation part 8 is actuated to open swith 5, and the current of coil 1 flows to protective resistance 4. In this case, the value of resistance 4 is set small enough to the resistance of switch 5 at the off-time when the resistance connection is given to switch 5 with the circuit not opened like the thermal permanent current switch. Thus, the energy discharged within cryostat 2 can be reduced.
