Title: Magneto-optical reproducer
Inventor: NIIHARA TOSHIO
IPC: G11C13/06
Filed: 1982-08-27
Abstract: PURPOSE:To obtain a large output of reproduction, by providing an analyzer and a photodetector at both sides of a recording medium, and making use of both Kerr effect of reflected light and Faraday effect of transmitted light at a time to perform a magneto-optical reproduction. CONSTITUTION:The light sent from a laser light source 1 passes through a polarizer 2 and irradiated to a recording medium 4 after having its optical path bent by a half mirror 3. When the magnetization of the medium 4 is set upward, the polarized wave surface of the reflected light 6 turns by a Kerr revolving angle +thetaK to the polarized wave surface of the incident light 8. The light 7 transmitted through a substrate 5 turns by a Faraday revolving angle +thetaF. Then the light 6 passes through an optical detector 9 having its quenching direction turned by -thetaK and is detected by a photodetector 11. As the detector 10 has its quenching direction turned by -thetaF, no transmitted light 7 reaches a photodetector 12. Therefore, a reproduced signal having about doubled value of VR, where Vr is obtained when only the Faraday effect is used can be obtained by supplying outputs +VR and 0 which is applied with the photoelectric conversion by the detectors 11 and 12 to a differential amplifier 15.

Title: Exposure-to-electron beam controlling system
Inventor: NAKAMURA KAORU
IPC: H01J37/302
Filed: 1980-10-22
Abstract: PURPOSE:To ensure correct exposure free of deviation caused errors by a method wherein a position coordinates in an Xs-Ys coordination system is fed into control circuits after a system conversion when the coordinate axes Xs and Ys are deviated by angles alpha and beta from the orthogonal coordinate axes XL-YL. CONSTITUTION:A computer 6 outputs (uncorrected) signals which will set correcting factors D11, D22 and D12, D21 respectively at 1 and 0 that are to be determined by deviation angles alpha, beta, and alpha-beta, and designates the location for the platform 1 to reach in response to the signals by travelling in the directions Xs and Ys yielding a drawing. Deviation from the originally planned image is measured and deviation angles alpha and beta are determined, and correcting factors are calculated. A new location designated for the platform 1 by the computer 6 sending out corrected signals, multiplication circuits 7-10 respectively output D11x, D12y, D21x, and D22y. Then, D11x+D12y and D21+D22 are calculated in units 11 and 12, converting the coordinates. Control circuits 5X and 5Y drive pulse motors 2X and 2Y until the values of measurement in the laser distance measuring system 3 are equal to the coordinates after conversion. This construction eliminates errors that may be caused by non- parallelism between the axes XL & YL in the laser distance measuring system 3 and the axes of movement Xs & Ys of the platform 1, ensuring a drawing to be completed as planned.

Abstract: PURPOSE:To prevent falling to the outside of an escalator and further to increase the safety effect by making the longitudinal joint portions of a fence come in touch with each other and placing a part of the fence at the joint portion of the fence on the upper surface of a strut. CONSTITUTION:The weight Wa of a fence 13B adapted to move along a slipway of an escalator is supported by a fence 13A because it is in contact with the fence, and further the weight Wb working in the direction of gravity is supported by a strut 11 and a support because the lower end 13b with a projection size la forming a projecting portion 13a is placed on the respective upper surfaces of the strut 11 and a support 12.

Title: Communication control system
Inventor: SAKURADA KAZUYUKI
IPC: H04M3/60
Filed: 1999-05-27
Abstract: PROBLEM TO BE SOLVED: To suppress deterioration of the service to a customer and the increase in charged telephone rate, when no connectable operator exists at the time of connecting an incoming call from the customer to an operator selected from among a plurality of operators. SOLUTION: When no connectable operator exists upon receiving an incoming call, a call-back time predicting algorithm device 65 predicts the interval of time until a connectable operator becomes available. An IVR(interactive voice response) device asks the customer making the incoming call whether the customer will wait until the connectable operator becomes available, by holding the call or once disconnects the call and waits for call back from the operator side, while automatically transmitting the predicted interval of time. When the customer selects call back, asks the customer to inform the device 65 of the destination of the call back. Since the call back can be performed appropriately, the deterioration of service to the customer can be suppressed.

Abstract: PURPOSE:To shape pulse trains, by generating a comparison pulse with slightly narrower in width than a normal pulse, being triggered with pulses inputted having various widths, and making the pulse width narrower than the comparison pulse equal to the pulse of comparison pulse. CONSTITUTION:A comparison pulse generator 4 connected to a circuit to which pulse trains (d) with different width input to an input terminal 7, is operated at a leading edge of the pulse signal (d) and produces a comparison pulse (e) with slightly narrower than that of a normal pulse d1.

The pulse (d1) with wider width than the pulse (e) is taken as an output signal (g) as it is, and when a pulse (d2) with narrower width than that of the pulse (e) is inputted, the TR5 is conductive and a pulse f corresponding to e-d2=f is generated and it is added with the (d2) to be a pulse train (g). From the collector of the TR5, the detection signal (f) indicating the presence of narrow pulse is outputted. Thus, the pulse width can be corrected with a simple circuit to realize the duty ratio.
