Title: Transceiver connected with plural microphones and speakers
Inventor: TERAHASHI KATSUYUKI
IPC: H04B3/54
Filed: 1986-10-07
Abstract: PURPOSE:To easily give priority levels to respective microphones without using a switching circuit by connecting plural pairs of microphones and speakers to a transceiver body through a master transmitting/receiving means and a slave transmitting/receiving means and using an FM modulated wave for transmission from the slave transmitting/receiving means. CONSTITUTION:When a transceiver body 10 receives a radio wave, the radio wave is amplified and detected and an audio signal is transmitted from a master transmitter 15 to all slave receivers 25 by power lines. If a token switch 34 of some slave transmitting/receiving means 14 is depressed, a slave transmitter 20 of this slave transmitting/receiving means is set to the transmission state, and sounds inputted to a microphone 8 are FM-modulated and are transmitted from a power line 24 to a master transmitting/receiving means 13. In the master transmitting/receiving means 13, they are detected by a transmission/reception switching circuit to operate the transmitter of the transceiver body 10, and the audio signal received by a master receiver 16 is inputted to the transmitter 36 of the transceiver, and the transmitter transmits the audio signal. When FM modulated waves are simultaneously transmitted from the slave transmitting/receiving means, the strongest radio wave is received by the master transmitting/receiving means but weak radio waves are not received, and priority levels of microphones are easily adjusted.

Title: Auxiliary storage device
Inventor: SAKATA SHUICHI
IPC: G11B25/04
Filed: 1989-09-18
Abstract: PURPOSE:To shorten time for access and to extend recording capacity by providing plural rotary disks, which are fixed to the same rotary shaft in plural steps, around a positioner with the positioner as a center. CONSTITUTION:When a computer moves a correspondent head 3 to the track position of a disk, to which objective data are recorded, for example, a disk 1 or the track position of the disk 1 to be recorded, at such a time, another head 3' linked to the same positioner 5 separately shows the specified position of the track on a disk 1 as well. Accordingly, a cylinder on the disk 1 and a cylinder on the disk 1' can be accessed by one time access operation. As a result, the time for access can be shortened and the recording capacity can be extended.

Title: Semiconductor device
Inventor: YAMAMOTO TAKESHI
IPC: H01L21/60
Filed: 1985-10-25
Abstract: PURPOSE:To remove the abnormal temperature rise of one part of a semiconductor chip due to the uneven distribution of currents, and to increase surge current resistance and inrush current resistance by fixing a metallic electrode onto the upper surface of the chip and bonding an Al wire to the electrode. CONSTITUTION:An Al wire 15 is ultrasonic-bonded onto a metallic electrode 16 fastened onto a semiconductor chip 14. Currents from the Al wire 15 sufficiently spread even in the transverse direction in the metallic electrode 16 and flow on the whole surface of the semiconductor chip 14 in this device. Accordingly, currents are unevenly distributed on a contacting section between the Al wire and the semiconductor chip, thus preventing the generation of an abnormal temperature rise in one part of the chip.

Abstract: PURPOSE: To improve cooling effect of an inner portion of an upper portion of a piston by expanding a protrusion, which has a piston bottom as its base point and projects towards the center in an inner cooling chamber, towards an annular passageway of a lower portion, and using the same as a turning guide face of cooling oil. CONSTITUTION: An outer annular cooling chamber 8 and an inner cooling chamber 9 are connected with each other via an overflow hole 13. A concave wall 14 of a piston bottom is formed as a protrusion 16 projecting towards a lower portion 3 of the piston within a scope of a piston axis 15. The protrusion 16 is expanded downward to form an under cut, and a notch 17 opening to the cooling chamber 9 is formed in a middle portion. Cooling oil is supplied to the outer annular cooling chamber 8 through a hole 18 and enters the inner cooling chamber 9 from the overflow hole 13. Then the cooling oil is guided by the protrusion 16 to move rotationally in a direction shown by arrows 19, 20. As a consequence, the wall of the piston bottom 11 is strongly cooled, and cooling is also carried out at the notch 17.

Title: Arc furnace facility
Inventor: TAKAHASHI MAKOTO
IPC: F27D11/10
Filed: 1994-09-09
Abstract: PURPOSE: To prevent electrode fracture even at a large furnace body tilt angle by providing an electrode intermediate section holding device for the intermediate portion of an upper electrode lifted to a position above a furnace cover. CONSTITUTION: In the case of a 28" graphite electrode, a movable electrode 7, when sized to have approximately 2.8m length, comes to have three nipple connecting sections for jointing graphite electrodes to each other at a position under an electrode holding device 8. Also, the electrode 7 projects down approximately seven meters from the device 8. Thus, when a furnace is largely tilted in this state, the electrode 7 is broken at the connecting section of the graphite electrodes nearest the device 8, due to bending moment resulting from the own weight thereof. In order to solve such a problem, an electrode intermediate section holding device 9 to hold the intermediate portion of the electrode 7 is provided above a furnace cover.  As a result, two units can be operated without any increase in an electrode unit requirement, and an electricity unit requirement can be reduced, due to energy saving.

Filed: 1992-08-17
Abstract: PURPOSE:To increase the breakage strength of the optical connector by forming an oxide film on the surface of at least a guide pin V-groove of a V-grooved guide substrate of silicon. CONSTITUTION:In the top surface of the V-grooved guide substrate 1 of silicon, plural optical fiber V grooves 2 and guide pin V grooves 3 are formed, and oxide films 4 are formed on their surfaces. This V-grooved substrate 1 is made of silicon and the optical fiber V-grooves 2 and guide pin V-grooves 3 are formed by, for example, cutting.
