Inventor: YOKOGAWA TOMOYUKI
IPC: H01B11/22
Filed: 1998-01-16
Abstract: PROBLEM TO BE SOLVED: To provide an optical composite overhead earth-wire that can effectively receive tape-like optical coated fibers in its metal tube and is excellent in a loss characteristic and an instantaneous heat-resisting characteristic. SOLUTION: On an optical unit composed by laminating multiple tape-like optical coated fibers 1, placing a cushiony filler 2 around them, and storing them in a metal tube 3, double-layer metal wires 4, 5 of which twist directions are opposite to each other are placed. In the inside space of the metal tube, the space factor of the cushiony filler in a space excluding the tape-like optical coated fibers is 10-50%. Thereby, its initial transmission loss and loss increase characteristic at low temperatures are improved. In addition, a material having a heat-resisting property and tensile strength is used for the cushiony filler.

Title: Method for deformation working of optical fiber
Inventor: KIDA ARATA
IPC: G02B6/00
Filed: 1981-01-21
Abstract: PURPOSE:To make an optical transmission line of arbitrary shapes with good accuracy by putting an optical fiber consisting of a polymer material into molds, heating the same, removing the molds where a part thereof is in contact with the inside wall to allow the fiber to expand then pressing the molds to the fiber thereby shaping the same. CONSTITUTION:An optical fiber 21 is put into the hole made by combining molds 11, 12 coated with silicone oil, and a mold 13 coated with silicone oil is pressed to these. When the molds 11-13 are heated, the fiber 21 softens, shrinks axially and is sucked successively into the hole. At the point of the time when the fiber 21 abuts on the mold 13 and swells no longer, the mold 13 is removed. Since the fiber 21 swells upper than a face 20, the mold 13 is pressed and the upper swollen part is moved laterally. By the repetition of this, a shaped article 22 is obtd. Thereby, the optical transmission line of arbitrary shapes is made with good accuracy.

Title: Optical information reader
Inventor: YAMAMOTO MASAAKI
IPC: G11B7/005
Filed: 1988-01-14
Abstract: PURPOSE:To easily detect information recorded with high density, by providing an objective lens which condenses only a part out of reading beams passing a ring area coming off the optical axis of a pupil surface on an information recording medium. CONSTITUTION:The objective lens 5 is provided with a shielding plate 5a which shields a center part including the optical axis of a pupil surface. Therefore, after a reading beam emitted from a laser beam source 1 is condensed on an object 3 by a condenser lens once, only a component passing through the ring belt shaped aperture part of the pupil surface of the lens 5 is condensed on a disk plane 6 via a beam splitter 4. And the reading beam reflected on the disk plane 6 returns to the lens 5 again, and only the component passing the ring belt shaped aperture part is made incident on a detector 8. By constituting a device in such way, the expansion of the center part of a beam spot formed on the disk 6 can be compressed. Therefore, a spot size used for the reading of the information can be decreased, and it is possible to perform the reading of the information recorded with high density easily.

Title: Semiconductor device
Inventor: SAWARA KUNIZO
IPC: H01L21/60
Filed: 1990-01-16
Abstract: PURPOSE:To improve product yield without mechanical stress at a solder bump, deformation, damage, short-circuit between the bumps by arranging a flexible sheet between a substrate and the bumps. CONSTITUTION:A flexible sheet 17 is arranged between solder bumps 10 and a solder connection part 12. The sheet 17 is formed of a material which can absorb mechanical strain in the case of solder connecting such as low thermal expansion polyimide. It is deviated to a connecting direction so that solder bumps 10 are not opposed to the part 12. If the bumps 10 and the part 12 are deviated at the positions, a pattern of conductor wiring for connecting both is formed on the sheet 17. Thus, since the bumps 10 of a semiconductor chip 9 are merely brought into contact with the sheet 17 but not brought into pressure contact with a member at the side of a substrate 11, the bumps 10 do not receive mechanical stress, and deformation and connection between the bumps do not occur.

Title: Oily mist capture device
Inventor: OTA AKIRA
IPC: F24F7/007
Filed: 1989-01-13
Abstract: PURPOSE:To prevent the contamination around a cooking utensils induced by oil droplets scattered from a cooking pan by absorbing air from the central part of a blowoff duct by the use of a blower, discharging the air from a blowoff port, forming the flow of air curtain around the cooking pan, and providing a smoke elimination device on the suction side of the blower. CONSTITUTION:When a blower 7 is driven, the air absorbed from a suction port 5a, is discharged downward from a blow-off port 5b so that an air curtain flow 9 may be formed around a pan 2. Then, the air is absorbed again into the suction port 5a from the central part, flowing along a curved surface of the pan 2. The oil in the pan 2 produces soot 4 when it is heated, but the air curtain flow 9 prevents the soot 4 from spreading around the pan 2. When it is absorbed into the suction port 5a from the central part, the soot 4 can be eliminated by a smoke elimination device 8 so that clean air may be discharged as an air curtain flow. In this manner, the diffusion of the soot 4 is controlled so that the quantity of soot adhered to the walls around the pan may be minimized and the suction efficiency of the blower 7 may be enhanced as well.

Title: Sea bottom optical repeater
Inventor: HORIO MITSURU
IPC: H04B10/29
Filed: 1987-01-14
Abstract: PURPOSE:To facilitate retrieval at the fault point of an optical sea bottom cable by providing an optical switch applying tentative loopback of an input terminal of each recovery repeater section to the output terminal of an opposite side repeater section. CONSTITUTION:Just after a control signal 8 passes through an optical switch 2a via a forward pass recovery repeating section 11, the optical switch 2a is switched. A control signal 9 passing through the optical switch 2a is a reflected light 10 at the fault point of the optical fiber, passes through the optical switch 2a, recovered by a return path recovery repeating section 12 and sent to a terminal station sending a control signal. The difference of the reception time of the recovered reflected light from the sent time of the control signal, that is, the division of the delay time by the propagation time per unit length of the optical fiber gives the measurement of the distance of the fault point of the optical fiber line including the sea bottom repeater. Thus, the location of the fault point of the optical fiber line including the sea bottom optical repeater is detected easily.

IPC: G11B11/105
Filed: 1981-01-22
Abstract: PURPOSE:To improve high-density recording characteristics by reducing a recording current by performing magnetic recording along a heating straight line while heating a magnetic recording medium with laser beam. CONSTITUTION:A main magnetic electrode 12 is made of a magnetic thin film with high magnetic permeability on an insulating transparent base 13 made of sapphire, etc. On the reverse surface of a magnetic recording medium 11, an auxiliary electrode 14 is arranged opposite to the main magnetic electrode 12 and a recording current flows through a coil 15 wound around the electrode 14. Laser beam 17 from a laser beam source 16 is transmitted through the base 13 to irradiate the magnetic recording medium 11, which corresponds to the tip part of the main magnetic pole 12, with the laser beam, thereby heating the recording medium 11. Thus, the recording current is reduced to improve high-density recording characteristics.
