Title: Video signal separation circuit
Inventor: SENUMA TOSHITAKA
IPC: H04N9/78
Filed: 1990-02-15
Abstract: PURPOSE:To prevent dot disturbance by selecting a 2nd band pass filter section with a switching means when an edge detection section detects an edge, in which a color signal is subject to change. CONSTITUTION:When an edge detection circuit 5 detects a change point of a color, a switch element 7 is selected as shown in broken lines by a signal sent from the edge detection circuit 5 to the switch element 7, and a broad band BPF62 is selected. The change point of the color is detected by the edge detection circuit 5 to select band pass filters 61, 62 whose pass band differs and the broad band BPF62 is used at the edge of the signal C to extract the signal C. Thus, the dot disturbance is reduced.

Filed: 1996-02-22
Abstract: PROBLEM TO BE SOLVED: To enable measuring axial tension with high precision, by obtaining the arriving time of a wave, on the basis of the time phase wherein difference between the reflected wave distribution showing intensity of detected reflected wave every time phase and the reference wave distribution defined every time phase by constant intensity becomes minimum. SOLUTION: A second part member 16 is fixed to a first part member 12 by screwing a bolt 10 in a tapped hole 14 of the first part member 12. Ultrasonic wave probe 22 is closely brought into contact with the head part 20 of the bolt 10. Ultrasonic wave is applied to the bolt 10 from the probe 22, which receives the reflected wave from the bolt tip 24. The signal waveforms of the incident wave and the reflected wave are sent to a signal processing equipment 28 via an A/D converter 26. Out of the reference wave distribution defined every time phase by specified intensity, the reflected wave when the difference from the reflected wave distribution becomes minimum is selected, thereby obtaining the propagation time of the ultrasonic wave from incidence to reflected wave reception.  The length of the bolt obtained from the propagation time is compared with the previously obtained length of the bolt 10, and the stretch amount of a bolt shaft 18 is calculated. From this amount and the Young's modulus of the bolt 10, the axial force is operated with an axial force calculator 30.

IPC: H04N7/08
Filed: 1988-02-19
Abstract: PURPOSE:To receive a multiplexing signal without fail by making an interference removing signal corresponding to multi-pass interference from a received sound sub-channel signal and canceling the interference. CONSTITUTION:A band pass filter (BPF2) 30 extracts the sound sub-channel signal from a sound base band signal and a sound sub-channel signal 31 is two-multiplied by a two-multiplying circuit 32. Then, a mu<2>(t) is obtained. Next, the mu<2>(t) is differentiated by a differention circuit 36 and a dmu<2>(t)/dt is obtained and the amplitude of a differentiation signal is corrected by an AGC circuit 38. Then, the delay quantity of a circuit from an input signal 20 is mixed with a signal 24, which is corrected by a delay circuit 22, by a mixer 26 in a reverse phase. A mixed signal 28 obtains a band from 3fH to 4fH and it is obtained as a signal 42 for control by a BPF444 which can remove the part of a sound control signal. Further, the delay circuit 22 is controlled as the delay circuit with tap so that the control output of a detecting circuit 40 to an AGC circuit 39 can be minimum. Thus, a phase change, which is generated by the multi-pass interference is decreased.

Filed: 1982-03-09
Abstract: PURPOSE:To prevent the shortcircuit of a control transistor by turning a start control signal to OFF for a predetermined time by the variation in the instructing direction of a rotating direction instruction signal. CONSTITUTION:When a start control signal ON/OFF is set to ''H'' level, the output of an AND circuit U9 becomes ''H'' level, and when a rotating direction instruction signal CW/CCW is set to ''H'' level, control transistors Q1, Q2 become ON, and a motor M rotates normally. When the signal CW/CCW is set to ''L'' level, the transistors Q1, Q3 becomes OFF, while Q2 becomes ON. Then, the output of an AND circuit U9 becomes ''H'' level in delay by the time corresponding to the time constant of the delay circuit having a resistor R and a condenser C, the transistor Q3 becomes ON, and the motor M rotates reversely. In this manner, the shortcircuit of the control transistors can be prevented.

Abstract: PURPOSE:To improve the separability of a paper which is fed again from an image transfer medium and to prevent the paper from being jammed by providing a means which can selectively reverse the rear surface and front surface of the paper between a paper ejecting part and a paper housing part and making the taking up direction of the paper housing part the same as the rotation of the image transfer medium in an image producing device main body. CONSTITUTION:The reversing means which can selectively reverse the rear surface and front surface of the paper is provided between the paper ejecting part in the image producing device main body 1 and the paper housing part 200. Then, the paper taking up direction by a belt 240 in the paper housing part 200 is constituted to be the same as the rotation of the image transfer medium 10 in the image producing device main body. The winding paper, which is easy to be wound by being taken up with the aid of the belt 240 is brought into contact with the medium 10 under the state that the winding direction is in an opposite direction to the curvature of the medium 10. Therefore, the paper is taken up to the belt 240 by turning the copied surface thereof inside at the time of a both-surface copying mode and it is taken up by turning the copied surface outside at the time of a composite copying mode. Thus, since the winding direction of the paper is made to be the opposite direction to the curvature of the image transfer medium in any copying mode when the paper is fed again to a transfer part, the paper is easily separated from the surface of the medium.
