Title: Vertical synchronizing circuit of television receiver
Inventor: TAKASHIMA JIYUUICHI
IPC: H04N5/06
Filed: 1979-09-28
Abstract: PURPOSE:To attain quick response by varying the integral effect of a resetting pulse to a counter according to the magnitude of a received broadcast wave. CONSTITUTION:The voltage value of an arrival AGC signal expresses the magnitude of a received broadcast wave, i.e. a television signal and when cumulative output (h) of accumulator 10 increases on the basis of this arrival AGC signal VC, reset signal (g) is sent to counter 4. Therefore, since the voltage value of AGC signal VC is small when the television signal is weak, output (j) of AGC signal input circuit 22 is great and the accumulation time of accumulator 10 is prolonged, reducing the probability of a synchronization miss. On the other hand, since the voltage value of AGC signal VC increases as the television signal becomes stronger and stronger, output (j) of AGC signal input circuit 22 decreases, shortening the accumulation time of accumulator 10. In case that a radio wave of a relatively intense electric field is received, the probability of a synchronization miss is reduced without prolonging synchronism acquisition time unnecessarily.

Title: Method and device for detecting focus
Inventor: TSUDA HISATSUNE
IPC: G02B7/28
Filed: 1980-09-11
Abstract: PURPOSE:To facilitate optical adjustment and to simplify constitution by making reflected light incident to an optical member having a reflecting surface at an angle less than a critical angle, and by detecting and comparing the quantity of reflected light from the reflecting surface with a prescribed threshold level. CONSTITUTION:Reflected light from the reflecting surface 27a of a detection prism 27 is photodetected by a photodetector 28. As a disk 26 in an in-focus state is distplaced in a direction (a), the angle of the incidence of light to the reflecting surface 27a approximates a critical angle, so the quantity of the light incident to the photodetector 28 increases. As it is displaced in a direction (b), the quantity of the incident light decreases. The output of the photodetector 28 is supplied to one input terminal of a differential amplifier 34, and a reference voltage Vr from a reference voltage source 35 to the other input terminal. This voltage Vr is set nearly equal to the output voltage of a low-pass filter 33 in the in-focus state. Consequently, focusing-error signals showing the direction and extent of displacement of the disk 26 from an in-focus position are obtained from the output terminal of the differential amplifier 34. Thus, optical adjustment is facilitated and constitution is simplified.

Abstract: PROBLEM TO BE SOLVED: To reduce the load of a system at the time of communication start by starting a communication path control program from both computers before the start of a communication program and establishing a logical communication path to be used for each communication program. SOLUTION: When a communication path control program 11 is started at a computer 1, the logical communication path is established with a communication control program 21 of a computer 2 as a communicating party. Namely, communication programs 12 and 13 respectively use logical communication paths 121, 122, 123, 131, 132 and 133 for communication with communication programs 22, 23 and 24. Afterwards, when the communication program 12 or 13 of the computer 1 is to start the communication with the communication program 22, 23 and 24 of the computer 2, since the logical communication path is already established between the communication control programs 11 and 21, communication can be started without newly establishing any logical communication path.

Abstract: PURPOSE:To prevent lowering of processing precision and disconection of a wire, by a method wherein a means is provided for detecting consumption of a feeder feeding an electric discharge power to a wire electrode, and worsening of a contact state between the wire electrode and the feeder is previously reported to a worker. CONSTITUTION:Since, in the running state of a wire electrode 10 before consumption of feeders 26 and 28, the wire electrode 10 is pressed by an amount equivalent to a deviation amount of the feeder 26 to sqeeze the wire electrode, a contact therebetween is sufficient, and stable high-precise processing takes place. When consumption of the feeder 26 is progressed, a wire running passage is brought into an approximately linear state which is set by a diamond dice 14a of a wire guide 14 and a diamond dice 22a of a lock screw 22. When consumption is progressed to some set amount, the wire electrode 10 is brought into contact with a detecting means 40 or a contact shoe if the detecting means is a contact detecting mechanism. By means of a detecting signal therefrom, alarm is displayed, and consumption of the feeder is previously reported to a worker. This constitution prevents lowering of processing precision and disconnection of a wire.

Filed: 1990-05-16
Abstract: PURPOSE:To maximize a data transmission speed of a digital line with respect to a maximum data transmission speed processed by a G-3 facsimile equipment by inserting a dummy data to a signal at a speed less than the data transmission speed in the digital line, extracting the dummy data from the received digital signal and adjusting the data speed by a memory section.

Title: Rotation sensor
Inventor: YANO NOBUYOSHI
IPC: G01D5/245
Filed: 1998-05-08
Abstract: PROBLEM TO BE SOLVED: To obtain a highly reliable rotation sensor in which deterioration of the characteristics due to external stress is prevented by disposing a core having high Barkhausen inversion characteristics in a tubular glass. SOLUTION: A linear or stripe core 1 having high Barkhausen inversion characteristics is disposed in a resin bobbin 2 applied with a detection winding 4. The core 1 is disposed in a tubular glass 3 interposed between the bobbin 2 and the core 1. Since the core 1 is disposed in the tubular glass 3, it is substantially insusceptible to expansion/contraction of the bobbin 2 due to exposure of the sensor to high or low temperature. Consequently, output voltage characteristics are prevented from deteriorating due to stress and a rotation sensor exhibiting high sensitivity and accuracy over a wide temperature range can be obtained. High Barkhausen inversion characteristics represent a phenomenon where inversion of magnetization take place instantaneously at some threshold value of applying field.

Filed: 1988-05-24
Abstract: PURPOSE:To improve the quality of video recording at a VTR and a video image watched by a television receiver by increasing a distribution signal level used for video recording of an opposite broadcast program by the VTR. CONSTITUTION:A television signal and an FM signal of a CATV inputted to an input terminal 1 are distributed by a distributer 2 and the distributed one signal (a) is inputted to a tuner section 3. The other distributed signal (b) is amplified by a preamplifier 5 and further distributed by a distributer 6.

Title: Valve element for butterfly valve
Inventor: HISADA KOICHI
IPC: F16K1/226
Filed: 1996-04-23
Abstract: PROBLEM TO BE SOLVED: To achieve a resin lining containing a shaft seal and to facilitate incorporation in a resin seat ring by a method wherein a valve stem lining part having a resin lining layer formed along a valve spindle and the separate valve spindle inserted therein is formed at a cylinder body having an inside diameter coinciding with the outer shape of the valve spindle. SOLUTION: To insert a valve element 10 in a resin seat ring 18, after a valve spindle 13 on the drive side formed integrally with a core body 11 is first inserted in one valve stem hole of the resin seat ring 18, a valve spindle lining part 12b in which a valve spindle 14 on the floating side is inserted is inserted in the other shaft hole and the valve spindle 14 on the floating side is inserted in the valve spindle lining part 12b from the outside and joined with the core body 11. Since the valve spindle lining part 12b has no rigid body present therein, deformation is easy to occur.  Further, the minimum limit length of a cylinder part to be inserted suffices for insertion and since, in insertion in the resin seat ring 18, there is almost no need to deform the resin seat ring 18, there is no fear of the change of the shape and the size of the resin seat ring 18 due to deformation being produced.
