Title: Clock selection circuit
Inventor: AOKI KOUJI
IPC: G06F1/12
Filed: 1978-03-01
Abstract: PURPOSE: To prevent the error in read-in, by providing the memory circuit which reads in the first clock with one phase in the second clock of n-phase having a half the period, shift circuit, corelativity circuit, frequency demultiplication circuit and  selection circuit.  
     CONSTITUTION: The first clock input 9 and the second clock A having the half period of it are fed to FF1 and the output is picked up at the terminal 6 and fed to the shift register SR3, shifting the initial condition in synchronizing with the second clock. Two outputs Q 1  and Q 2  apart by one time slot for SR3 are fed to the corelativity circuit 4 and the corelativity signal of 1 for different code and 0 for the same code is fed to the frequency demultiplier 5. In this case, if read-in error is caused to FF1 with the stationary phase error, the output of FF1 is 0. Although SR3 is 1 for different code by the circuit 4 with Q 1  and Q 2  of initial condition 1, 0, since the output of FF1 is 0, the output of the circuit 4 changes from 1 to 0. The unit 5 uses this change and changes from 0 to 1, selecting the second clock to the third phase signal C via the switch 2 and feeding it to FF1. Thus, read-in error can be prevented.

Title: Semiconductor switch control circuit
Inventor: KAWARADA KUNIYASU
IPC: H02M1/08
Filed: 1980-02-29
Abstract: PURPOSE:To realize the both functions of ON and OFF with a single control input signal, by feeding the output of the main current monitor circuit back to the ON/ OFF driving circuit of the gate of a PNPN switch and thus securing a flow of the gate current only in the switch transient period.

On the other hand, the OFF current IOFF, N is flowed into the N gate N1 from the circuit 9 via D2 in a working mode of the gate N1; and the ON current ION, N is extracted ON to the circuit 3 from N1 via D3. The main current monitor circuit 8 detects the during ON or OFF of the PNPN switch 1, and then flows the gate current transiently and only in the transition period of the switch 1.

Title: Elevator group supervisor control device
Inventor: MIYATAKE GAKUO
IPC: B66B13/14
Filed: 1998-02-05
Abstract: PROBLEM TO BE SOLVED: To improve sevice to passengers without lowering transport efficiency during a time zone where up peak operation is performed. SOLUTION: Each elevator control device 4 enters a peak operation mode upon receiving a peak control signal 5, but a door closing button switching device 3 does not output a door closing button invalid signal 9 during a time zone where ascent demand has not reached its peak but outputs a door closing button invalid signal 9 to a car opened on a specific floor during a time zone where ascent demand has reached its peak. The validity and invalidity of the door closing button of the car opened on the specific floor are thus switched to perform control corresponding to the amount of ascent demand so as to improve service to passengers without lowering transport efficiency.

Title: Polarization maintaining optical fiber
Inventor: JIEEMUSU ROBAATO ONSUTOTSUTO
IPC: C03B37/012
Filed: 1990-02-02
Abstract: PURPOSE: To prevent the generation of an adverse effect due to bend by specifying the refractive indexes of a core and a jacket part formed within five fold of the radius of a mode field of a coat and the core. CONSTITUTION: The jacket part 18 formed within five fold of the radius of the mode field of the coat 14 and the core 12 has a substantially uniform refractive index smaller than that of pure silica at least by 0.005 and the refractive index of the core 12 is at least the same as that of pure silica. When a refractive index difference of 0.005 is formed, effective balance between signal attenuation and bend allowance can be attained. When an optical fiber is bent up to an abnormally small radius of curvature, a larger refractive index difference is required. Consequently an adverse effect clue to bend is not easily applied to the optical fiber.

Abstract: PURPOSE:To supply an extremely high-purity refined gas by providing an adsorbing means in contact with a gas, a means for keeping the adsorbing means at <= about 0 deg.C and a means for controlling the atmosphere around where the gas contacts the adsorbing means. CONSTITUTION:An adsorber 1 is arranged in an atmosphere control vessel 3 having an evacuating system for evacuating and thermally insulating the adsorber from the outside, and the surface is kept at a required temp. by a temp. control mechanism 2.

By such a constitution, the surface of the adsorber 1 is controlled below the condensing temp. of the impurities to be removed corresponding to the pressure in the vessel 3. Consequently, the impurities in the raw gas 5 are condensed on the surface of the adsorber 1, adsorbed and removed, and the extremely high-purity refined gas 6 is obtained.

Title: Circuit constitution and method provided with temperature dependent signal swing
Inventor: GREGORY SCOTT WINN
IPC: H03F1/30
Filed: 1998-02-05
Abstract: PROBLEM TO BE SOLVED: To optimize the SNR of an input swing, and to minimize distortion over the entire range of an operation temperature by using a variable gain circuit controlled by the control signals of a temperature control circuit and controlling the signal swing of input signals so as to fluctuate along with temperature fluctuation within the effective linear signal range of an analog circuit. SOLUTION: Through the variable gain circuit 20 provided with an amplifier circuit for varying a gain in an optional range less than '1' and practically attenuating the input signals by being controlled by the control signals of the output of the temperature control circuit 40, the input signals are inputted to the analog circuit 30 of a bipolar differential amplifier provided with an input signal linearity limit for fluctuating along with the temperature. Then, the allowable swing of the input signals is limited, amplification is performed and the output signals 14 of the function of the input signals are outputted. Thus, the signal swing of the input signals is maintained at an almost fixed amount less than the maximum signal swing allowed by the analog circuit 30 at a given temperature, and even though a signal level is raised, noise is not increased corresponding to it.

Abstract: PURPOSE:To miniaturize a circuit by controlling an individual laser diode comprising a laser diode array with one photodiode and one laser diode current control circuit. CONSTITUTION:The photodiode 200 receives the monitor output light of the laser diode 350, and outputs it to the laser diode current control circuit 400. The circuit 400 performs voltage conversion and amplification 410 on a current from the diode 200, and finds the maximal value by a detector 430, and the minimal value by a detector 420, and difference at a subtractor 440. Thence, a control voltage can be outputted by inputting those values and difference to relative computing elements 450, 460. A bias current can be set at the optimum threshold value for the laser diode 310 by inputting the control voltage to a laser diode drive circuit array 100. The light output of the diode 310 is adjusted by a reference level VR2 inputted to an input terminal 65. Thereby, the light output of the laser diodes 310-350 can be equalized.

Filed: 1982-02-18
Abstract: PURPOSE:To reduce a write current greatly, and to enable complete erasure and to perform repetitive operation stably, by performing the writing and erasure  of a storage element which utilizes Josephson effect while placing a superconductor thin-film line of the second kind in an invariably conductive state by  providing a resitive thin-film line. CONSTITUTION:On a substrate 6, an insulator thin-film line 5 is provided between the resistor thin-film line 3 and superconductor thin-film line 1 of the second kind for information storage to form a superconductive storage element. For writing to this element, a bias current IB is flowed from the upper electrode thin-film line 2 of a superconductor to the thin-film line 1 and a current IR large enough to holding the thin-film line 1 above critical temperature and make it invariably conductive is flowed to the resistance line 3 to allow magnetic lines of force to enter the thin-film line 1 (shown by A); and then the current IR is ceased and eddy flux is left at the thin-film line 1, thus completing the writing. For erasure, only current IR is flowed without flowing the current IB to make the thin-film line 1 invariably conductive, so that the erasure is performed completely even if there is a pin (irregular eddy flux) in the line 1. The writing requires the current nearly one eightieth as great as usual.
