Title: Signal selection circuit
IPC: H03H7/48
Filed: 1992-03-16
Abstract: PURPOSE:To prevent deterioration in an output waveform by avoiding termination of a branch circuit when one signal selection circuit is not mounted while an electric signal is switched through the use of plural signal selection circuits. CONSTITUTION:The signal selection circuit 3 consists of a branch circuit 5, a selection circuit 7, a termination circuit 11 of the branch circuit, a mount state selection section 13, and a relay 9. When the signal selection circuit 4 is mounted, the mount state detection section 13 uses the relay 9 not to activate the termination circuit 11 and when the signal selection circuit is not mounted, the detection section uses the relay 9 to activate the termination circuit 11. Thus, the deterioration in an output signal is avoided by allowing the signal selection circuit to connect the termination circuit to the branch circuit via the mount state detection section.

Title: Rotary transmission mechanism
Inventor: KURIHARA SEIICHI
IPC: F16H3/44
Filed: 1987-03-12
Abstract: PURPOSE:To maintain constant speed rotation of an output shaft and to increase initial torque, by enabling application of electromagnetic braking onto a ring gear in a planetary, gear system and fixing a flywheel to the ring gear. CONSTITUTION:In a planetary gear system rotary transmission mechanism, a plurality of electromagnets M1-Mn are arranged on a bearing board BP while facing with the sideface of an annular flywheel F fitted over the outer circumferential face of a ring gear GR. When a heavy load is applied onto an output shaft Po, power is fed to the electromagnets M1-Mn prior to start of a motor M and braking is applied onto the ring gear GR. Here, initial braking can be increased through function of inertia moment of the flywheel F. Consequently, a large torque can be obtained from the output shaft Po, although revolution of planetary gears G1, G2 is decreased. When rotation of the flywheel F is increased, power supply for the electromagnets M1-Mn is controlled according to rotation of the output shaft Po and the ring gear GR is braked, so as to rotate the output shaft Po with constant speed.

Title: Radio multiple address communication system
Inventor: KUROKAMI YUUZOU
IPC: H04B7/26
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To provide a radio multiple address communication system with a high frequency utilizing efficiency by using the same frequency for a transmis sion frequency of each cell in the radio multiple address communication system using the cell system. SOLUTION: A center station 10 uses a transmission reference signal oscillator 13 to generate a transmission efficiency and distributes the signal to each base station with a modulation signal. A base station 20 uses a voltage controlled local oscillator 26 deciding a transmission frequency to synchronize the transmission frequency with the received transmission efficiency. As a result, the transmission signals from each base station 20 are all frequency- synchronized. A subscriber station 30 uses an equalizer 34 to eliminate interference even on the occurrence interference of adjacent cells.

Filed: 1989-03-10
Abstract: PURPOSE:To improve the efficiency of emitting and receiving light and to accurately discriminate a liquid type by providing an optical fiber, a microlens and a reflecting mirror. CONSTITUTION:Signal light is supplied to the microlens 3 on a light emitting side from a light emitting unit through the optical fiber 2 and the signal light received by the microlens 6 on a light receiving side is connected to an operational amplifier and a discrimination circuit through the optical fiber 7.

The cylindrical body 9 is inserted in a liquid feeding tube 10 and simultaneously constituted by being opposed to the reflecting mirror 5. Since the collimated beam of light is formed in such a way and the signal light is clearly caught by the lens having the improved efficiency of the emitting and receiving light, the effect of diffused external light is reduced and the liquid type is accurately discriminated. Besides, since the direction of the light can be changed by 180 deg., the structure of a sensor is miniaturized.

CONSTITUTION:For the P-(Al0.5Ga0.5)0.5In0.5P clad layer grown on a diffraction grating 17, the forbidden band width becomes wider than that of the P-(Al0.5Ga0.5)0.5In0.5P clad layer 2b grown on a flat face 16 through one time growth, and a real refractive index guide is made in the transverse direction of a Ga0.5 In0.5P active layer 3, and the generated light is confined in the active region without being subjected to absorption. Moreover, the effect of the P-Ga0.5In0.5P buffer layer 7 inserted between the (100) P-GaAs substrate 1b and the P-(Al0.5Ga0.5)0.5In0.5P clad layer 2b lessens at a diffraction grating 17, so the resistance to the currents flowing in the Ga0.5In0.5P active region 3 increases, and leak currents decrease. Accordingly, the threshold current can be made small.

Abstract: PURPOSE:To make it possible to coating accurately with an adhesive regardless of skill of an operator and to attempt to decrease adjusting work by engraving a recessed part along the longer direction of a core material at a position where the core material is coated with the adhesive and feeding the core material. CONSTITUTION:After a cut core material 2 is guided by a mold guide 3, the core material is passed through between the first adhesive coating member 7 to coat proper positions of a supporting part 2c, an upper end part 2a and a side end part 2b of the core material 2 with the adhesive. Then, when this core material 2 is passed through between the second and the third adhesive coating members 10 and 11, a position which is 0-0.5mm retreated from recessed parts 2d and 2e is coated with the adhesive. In this instance, the adhesive enters naturally into the recessed parts 2d and 2e of engraved lines caused by a capilarity and the adhesive is stopped on the lines of borderlines of these recessed parts and does not enter into the range H where it is not to be coated furthermore. There is therefore no possibility of overcoating or shortage of coating of the adhesive. In the core material 2 thus coated with the adhesive, the part coated with the adhesive is coated with a resin by extrusion molding of the resin.
