Patent JP-H09274672-A (JP)
Title: Automatic ticket examination machine
Inventor: KOMORI MIKI
IPC: G07B15/00
Filed: 1996-04-05
Abstract: PROBLEM TO BE SOLVED: To detect the drop of separation ability and to prevent the occurrence of a separation error by reporting the timing of maintenance and inspection for a separation part when a thickness detecting means detects the thickness of a train ticket more than two overlapped thickets over prescribed frequency. SOLUTION: A thickness detector D has a conductive movable roller 11, which is always pressed on the side of a fixed roller 10, on the upside of the fixed roller 10 and an eddy current is radiated from a transmitter 12 toward this movable roller 11. When the movable roller 1 is changed by an object to be conveyed such as a train ticket (a), it is measured as the change of a gap between the fixed roller 10 and the movable roller 11. In this case, the separation error occurs at a separation part S and when the thickness detector D detects thickness more than two train tickets, that detection timing is stored in the memory of a controller C.  When the thickness detector D detects thickness more than two train tickets more than prescribed times within prescribed time, the controller C outputs a signal showing the timing of maintenance and inspection for the separation part S and that timing is reported on a display.

Title: Reference frequency oscillating method for phase-lock loop
Inventor: TAKESHITA MASARU
IPC: H03L7/183
Filed: 1979-08-31
Abstract: PURPOSE:To ensure the variation of the reference frequency by an extremely small amount, by divinding the frequency of the crystal oscillator to obtain plural numbers of frequencies and then compounding these frequencies to secure a digital change of reference frequency. CONSTITUTION:The output frequency f1 of the crystal oscillator 21 is divided to 1/2 through the fixed frequency divider 22 to obtain frequency f2. And when the set signal has no agreement with the frequency f2, the switch gate circuit 23 gives a passing to the frequency f2. And this output is counted up by the counter 24. And when the count value coincides with the preset signal, the circuit 23 gives a passing to the f1 via the coincident detecting circuit 25. The fixed frequency divider 27 is connected to the rear stage of the oscillator 21, and thus the signal using the fixed time T as one cycle is delivered. Then the frequency f1 is counted up to the time T. At the time T, both the circuit 25 and the counter 24 are reset, and the counter 24 starts counting of the frequency f2.

Abstract: PURPOSE:To enable the attainment of the maximum detection sensitivity without changing the shape of a constant polarization optical fiber forcibly and thereby to improve reliability, by providing a light frequency modulator for one of two constant polarization optical fibers so as to give a phase difference to a divided wave light. CONSTITUTION:A laser light from a laser light source 1 is divided in two by a photocoupler 2, and one of them, a right-handed light is changed in phase in accordance with a change in sound pressure by a sound-field detecting constant polarization optical fiber 3 which changes in a shape according to a sound field. The other of the divided lights, a left-handed light, is given a required phase difference by a light frequency converter 4 subjected to feedback control, and it is propagated through a constant polarization optical fiber 5 for delay. The right-handed and left-handed lights are subjected to composition and interference in the coupler 2 and received by a photodetector 6. The phase difference given automatically by this converter 4 can be made an integral multiple of pi/2 constantly. Therefore the sensitivity of detection by the detector 6 is made to have a maximum value without changing the shape of the constant polarization optical fiber forcibly, and thus the reliability is improved.

Filed: 1990-04-26
Abstract: PURPOSE:To replace recording paper quickly by devising the recorder such that shortage of recording paper is sounded from a speaker when recording paper runs short and a notice means installed at a location apart from a recorder informs the shortage of the recording paper. CONSTITUTION:When a recording paper sensor 12 detects shortage of recording paper or an end mark, the recording paper sensor 12 outputs a detection signal to a CPU 31.

The operator easily recognizes the shortage of recording even when the operator does not visit a facsimile equipment 1, that is, the recorder while distinguishing the sound from other noise even in an office with large noise. As a result, the operator quickly takes counter measures for the shortage of the recording paper and the utility of the recorder is improved.

Filed: 1977-09-19
Abstract: PURPOSE: Small and large diameter pipes are overlapped and ultrasonically soldered in a soldering bath. While the pipes are moving up from the bath, one or more of ultrasonic vibrations are applied to them to remove imperfect solder portions and to provide a good joint with high reliability.  
     CONSTITUTION: A copper or other inside pipe 12 is soldered at its tip end and inserted into an aluminum or other outside pipe 11 to a predetermined depth. Both pipes are soldered together in a soldering bath using ultrasonic vibration. When pipes 11 and 12 are lifted from the bath, ultrasonic vibration is again applied. This causes to lower the molten solder between pipes, to remove unalloyed portion 13a produced on joint surface, and maintain wettability between solder and pipes. The pipes are then cooled. To be more effective, ultrasonic may be applied more than one times before the end of outside pipe 11 leaves the surface of soedering bath.
