Title: Seabed cable with bimetallic tube core containing optical fiber
Inventor: TETSUKUUCHIE CHIYUU
IPC: H01B11/22
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To provide a submarine cable which has optical fiber airtightly sealed without using a welded steel pipe and is excellent in a strength characteristic. SOLUTION: A cable core 20 is provided with an inside C-shaped pipe 15 almost closed by extending in the longitudinal direction and an outer pipe 18 which is arranged in a concentric circle shape around the C-shaped pipe 15 by an almost tight fit method and extends in the longitudinal direction by being airtightly sealed. The C-shaped pipe 15 is useful to protect optical fiber 25 from crushing, impact and pressure, and is advantageous since tensile strength of an optical fiber cable is also improved. When the C-shaped pipe 15 is used, the optical fiber can be efficiently introduced into an inside cavity of the C- shaped pipe 15 when the cable is produced. Since the C-shaped pipe 15 provides a desired strength characteristic of the cable core 20, it is advantageous since the outer pipe 18 can be optimized to airtightly seal the optical fiber in the cable core.  Therefore, the outer pipe 18 can be designed according to its sealing characteristic and a manufacturing characteristic without considering a mechanical characteristic such as strength so much.

Title: Elevator guide rail support device
Inventor: MIZUNO YUKIOMI
IPC: B66B7/02
Filed: 1989-04-26
Abstract: PURPOSE:To enable the support of a guide rail without demounting a lift body from the rail by providing a pair of installation members for mounting and supporting a rail support frame between a cushion member and an elevator trunk inner wall. CONSTITUTION:Upon occurrence of an earthquake, vibration energy causing the rocking of the side wall 1 of an elevator trunk is absorbed with the elastic ity of a cushion member 6 formed with an elastic material, and rocking vibra tion energy generated on a counterweight 11 is diffused via the cushion member 6. Also, the occurrence of strain including the shift of the fitting position of installation members 2a and 2b mounted on the side wall 1 caused by the rocking of the aforesaid wall 1, is reacted with the expansion and contraction of the cushion member 6. A distance between two guide rails 7a and 7b for mounting the counterweight 11 in a free state is always kept constant. According to the aforesaid construction, the counterweight 11 is not disengaged from the guide rails 7a and 7b, even if the side wall 1 is subjected to a rocking vibration.

Title: Wire bonding apparatus for semiconductor device
Inventor: YAMAGUCHI TETSUJI
IPC: H01L21/60
Filed: 1981-07-08
Abstract: PURPOSE:To provide a fine wire with the suitable slack of mountain contour by using a second clamper at a specified distance up from a capillary, clamping the fine wire when moving the capillary after the first bonding, then releasing it after the second bonding. CONSTITUTION:A second clamper 11 is provided at a specified distance down from a first clamper 7 while up from a capillary 5 and is movable up, down and laterally with the capillary. The second clamper 11 is usually held open and clamps a fine wire 6 after the wire is bonded to an element 4 and the capillary 5 reaches above a lead 1 for external connection. The capillary 5 descends to press and bond the fine wire 6 to the lead 1 by means of ultrasonic bonding. The clamper 11 will open after completion of the bonding. This process enables the length of the fine wire 6 drawn under the capillary 5 to be always constant for the next bonding, thereby producing a stable wire loop having the suitable slack of mountain contour and preventing broken wiring otherwise caused by slight external force.

Title: Manufacture of approximately spherical hollow product by cold forging
Inventor: SUZUKI TAKAMITSU
IPC: B21K1/02
Filed: 1977-09-06
Abstract: PURPOSE: To highly effiently manufacture the approximately spherical hollow product with accurate outer spherical surface without flash, by cold forging the previously prepared thick-walled cylinder of a specified length without restraining the inner diameter, so as to gradually reduce the outer diameter toward both end portions, and also, by forming the outer surface into approximate sphere.  
     CONSTITUTION: The specified thick-walled cylinder is previously prepared from the rod type raw material; this cylinder is set in the space formed by punches 1, 2, 3, 4, and is pressed; hereby, the approximately spherical hollow product 5 is formed. In this case, the lower dies 3, 4, have floating springs 8 in the horizontal direction between the shrink ring 6 and the fixing member 7, on purpose to prevent the miss shift of dies 3, 4; when a miss shift happens in dies, the lower dies 3, 4, being guided by the thick-walled cylinder, horizontally move on the surface of the bearing member 9, and hereby, the miss shift of dies is dissolved. Besides, the excess metal at nighborhood of both end portions flows into the gutter during the forming work, so that the thick-walled cylinder does not receive high pressure; therefore, the flash does not flow out into the outer spherical surface, and then, the product 5 with highly accurate outer spherical surface can be manufactured.

Title: Gas laser oscillator
Inventor: OOISHI YUUJI
IPC: H01S3/0971
Filed: 1984-05-29
Abstract: PURPOSE:To change a pulse discharge current waveform into an accurate pulse waveform, which hardly gets out of shape, by connecting first stabilized resistors limiting currents from an excimer power supply to each cathode, connecting second stabilized resistors limiting currents from a power supply for main discharge in parallel with several first stabilized resistor and connecting reverse-current preventive elements in series with the second stabilized resistors. CONSTITUTION:When excimer discharge is generated between an anode A and one proper cathode K1 and excimer discharge is not generated among the anode A and other cathodes K2-K5, currents flowing through the cathode K1 from the anode A are returned to a excimer power supply ES through a first stabilized resistor RS1. One part of currents intends to flow through other second stabilized resistors RM2-RM5 through a second stabilized resistor RM1 and a reverse-current preventive element D1 at that time, but currents do not flow through each second stabilized resistor RM2-RM5 because reverse-current preventive elements D2-D5 are connected. Accordingly, voltage among the anode A and other several cathode K2-K5 is kept at the voltage of the excimer power supply ES even when excimer discharge is generated only between the anode A and one proper cathode K1.
