Title: Transmitting circuit of pulse signal
Inventor: OOYAMA TETSUMASA
IPC: H04L25/49
Filed: 1981-07-10
Abstract: PURPOSE:To obtain impedance matching between a device and a load, by forming two closed loops from the middle point of a winding via a resistance and providing a switching circuit to each closed loop and turning on the switch circuits provided in these closed loops when no pulse signal exists. CONSTITUTION:When ''0'' of a bipolar signal is transmitted, both the switch circuits 22 and 23 are opened with the switch circuits 24 and 25 closed respectively. In this case, two closed loops are realized at an output transformer of a circuit 20. The resistance of a resistance circuit 13 for matching is connected to the middle point of the transformer of the circuit 20 and does not contribute to a matching action of impedance. Thus the two windings of the transformer of the circuit 20 are terminated by the matching resistances of the resistance circuits 26 and 27 respectively to realize the matching of impedance with the load ZL of a circuit 15.

Title: Apparatus for detecting change quantity of angle-of-rotation position
Inventor: TANAKA HISAO
IPC: G01B7/00
Filed: 1985-05-20
Abstract: PURPOSE:To enable accurate positional control without the erroneous operation of a resolver, by dividing the one rotation range of a rotor into a plurality of regions and calculating the displacement quantity of an angle-of-rotation position by a judge signal when said position passes between first and final regions at every cycle. CONSTITUTION:A binarization circuit 1 inputs the signal Pf from a resolver and a positional deviation operating circuit 12 takes in the binarization data from the circuit 11 at a sampling cycle to output the positional deviation pulse DELTAP having the pulse number proportional to the deviation of the lately binarization data with the previous one. A deviation counter 13 performs not only the addition input of the pulse member proportional to position change quantity as a position set value Ps but also the subtraction input of the pulse DELTAP to perform the data output of the calculation value of the difference thereof. A D/A converter 14 outputs the speed order Ns corresponding to said output. The circuit 12 divide a digital value D into four regions in order to obtain said value from the circuit 11 and obtains a region judge code (m) from two upper rank bits. The code (m) is used as a judge signal for judging whether the angle-of-rotation position of a motor passed a change-over point by a selection circuit 15 and the change quantity of the angle-of-rotation position at every sampling cycle is calculated.

Filed: 1979-08-27
Abstract: PURPOSE: To enhance the controllability of the pattern input device with a simple constitution, by securing a conduction between the adjacent linear conductor and linear resistor at the writing point and via the pressure-sensitive conduction sheet and then detecting the positions in the directions of the length and the right angle each.  
     CONSTITUTION: The output of the counter 30 turns on successively the change-over switches S 1 WSn via the decoder 31 and then drives successively the driving lines LD 1 WLDn. At the same time, the voltage V 1  and V 2  generated across the detection lines LS 1 WLSn formed with the linear resistors and via the load resistances RL 1 W RL 2  are applied to the analog adder 32 and the analog divider 33. Thus the position in the direction of length is detected to be supplied to the differential amplifier 34. Now if the driving line LDi is driven via the change-over swich Si, a conduction is secured between the lines LDi and LSi at the writing point P and via the pressure- sensitive conduction sheet. And then 1 is delivered from the level detector 36 to be applied to FF37. As a result, the operation of the counter 30 is discontinued, and the sample pulse is generated from the sampling pulse generator 40. And the position signals of the X and Y directions of point P are stored into the X and Y registers 41 and 42 each.

A phase comparator 7 compares the pulse P 2  with a standard pulse P 3  to produce its output, which is superimposed with the output voltage e' of the amplifier 2. The superimposed output is supplied to an amplifier 1 to thereby control the DC motor M at constant speed.

IPC: H04N9/83
Filed: 1984-05-30
Abstract: PURPOSE:To improve the S/N at a part where the color saturation degree of a carrier color signal is low and also to suppress the secondary distortion or a white-black inversion phenomenon caused at a part where said color saturation degress is high, by providing an amplitude control circuit that makes the amplitude of a color video part of a low band conversion color signal constant in level at the preceding stage of a mixing amplifier. CONSTITUTION:The carrier color signal of the color video signal supplied from an input terminal 1 is separated through a BPF2, and the amplitude of the video signal is limited by an amplitude control circuit 3. Then the video signal undergoes the low band conversion through a frequency converter 4. Thus a low band conversion carrier color signal is produced. The burst signal obtained by a burst signal sampling circuit 9 performs the switching control so that a changeover switch 13 is closed toward a contact (a) in a period of a color video part via an amplitude detection circuit 11 and then toward a contact (b) in a period of the burst signal. Then the circuit 3 controls the amplitude of the burst signal of the carrier color signal with the voltage of a fixed level given from a constant power supply 12 used as the control voltage. While the color video part is controlled by the control voltage produced by a color video part sampling part 8 and an amplitude detection circuit 10. Then the color video part is controlled so that its amplification factor is increased and decreased with small and large amplitudes respectively.

Filed: 1988-04-30
Abstract: PURPOSE:To reduce number of operational amplifiers having an expensive broad band characteristic by dividing an output voltage of a current source into a low frequency signal component and a high frequency signal component and applying current voltage conversion to the low frequency signal component by the operational amplifier for a low frequency band. CONSTITUTION:Output currents I1, I2 of current sources PD11, PD12 are divided respectively into low frequency signal components I11, I12 and high frequency signal components I12, I22. Thus, output voltages V11, V12 of operational amplifiers A11, A12 are similar low frequency signal components and become tracking and focusing signals. Moreover, the voltages V11, V12 are combined by an operational amplifier A3 and the combined signal and the split high frequency signal components before are subject to current voltage conversion by the operational amplifier A2. Thus, an output being the result of current voltage conversion to the total sum of input currents over the entire band appears as an output voltage V2 of the operational amplifier A2 and it is used as an information signal.

The control circuit 5 fetches it to generate the specifying data, thereby specifying a prescribed counting part of the counting circuit 3. Simultaneously, a high-speed pulse is applied from a high-speed pulse input terminal 8 to test the counting part. Thus, the number of external terminals is decreased without extenting the test time, thereby reducing the cost of an IC.
