Title: Color demodulating pulse generating circuit
Inventor: SUZUKI SUSUMU
IPC: H04N9/45
Filed: 1983-10-19
Abstract: PURPOSE:To execute stably a color demodulation by outputting a color demodulating pulse by frequency-dividing a sample pulse, only in case a phase difference between a timing pulse obtained basing on a color burst, and the color demodulating pulse is the same extending over an N horizontal period or above. CONSTITUTION:A phase difference detecting circuit 410 and a continuous phase shift detecting circuit 420 are added to a four frequency-dividing circuit 402 for outputting a color demodulating pulse 110 and they are provided on a color demodulating pulse generating circuit 400. A timing pulse 401 obtained basing on a color burst of an analog video signal is supplied to a shift register 412 constituted of four stages, also supplied to the circuit 410, and a phase difference to the pulse 110 is detected by the circuit 410. An output of a decoder 408 is inputted to the circuit 420, whether a phase shift is generated extending over four horizontal lines or more or not is decided, and a counter 402 is reset by a detecting signal of an OR gate 414. In this way, even in case of a signal whose S/N is low and a weak electric field area, the pulse 110 is generated stably, and a stable color demodulation can be executed.

Filed: 1993-07-09
Abstract: PURPOSE:To heighten turning performance and perform ABS control appropriately by correcting braking force control to rear wheels in the direction of increasing braking force by a correcting means at the time of detecting the steering state from a steering detecting means. CONSTITUTION:A sensor S6 detects the steering angle of a steering wheel among signals inputted into a control unit U, and braking force obtained by ABS control is corrected according to the steering wheel operating state.

Abstract: PURPOSE:To obtain the temperature control circuit capable of controlling a temperature within a constant range regardless of the degree of heat requirement by a method wherein a solenoid valve is utilized in this circuit to control the combustion amount of gas or kerosine. CONSTITUTION:In accompanied diagram, a set temperature is denoted by Ts, a temperature, one stage lower than Ts, is denoted by Ts-1 and the other temperature, further one stage lower than Ts-1, is denoted by Ts-2 while a temperature, one stage higher than the set temperature Ts, is denoted by Ts+1, and a temperature, at which temperature the combustion temperature is to be controlled, is refered to as Tp. When the Tp is to be increased, a strong combustion is continued as shown by numerass (1, 2, 3) in the diagram until Tp arises to a temperature near but slightly lower than the temperature Ts, then, a weak combustion is continued until the Tp arrives at Ts+1 as shown by numeral (4) in the diagram. When Tp decreases by the weak combustion, then, the strong combustion is effected again until it becomes lower than Ts-1 as shown by the numeral (6). When Tp has arrived at a temperature higher than Ts+1, the combustion is stopped as shown by the numeral (7). According to this method, Tp may be controlled within the range between Ts-1 and Ts+1 by repeating the strong and weak combustions or the weak combustion and the stoppage of the combustion.

Filed: 1996-07-24
Abstract: PROBLEM TO BE SOLVED: To well prevent a braided wire from being uncoiled by forming a coiled wire out of a coil wire of circular cross section and another coil wire of elliptical cross section, regarding an electrode coil. SOLUTION: A wire 1 not coiled is positionally adjusted, so as to become parallel to a first core wire 3. A braided wire 2 is wound around the wire 1 and the core wire 3. Then, a unit made of the coiled wire 1, the first core wire 3 and the braided wire 2 is wound around a second core wire 4. In this case, the second core wire 4 is flattened at equal intervals. As a result, the coil of the coiled wire 1 comes to have an elliptical cross section in the flattened zone of the core wire 4, while an electrode coil or the coil of the coiled wire 1 comes to have almost a circular cross section in the other zone of the core wire 4 than flattened. After a coiling process, each of the wires 1 to 4 are cut at the center of the flattened zone of the core wire 4.

A sample hold circuit 2 obtains a sampling value Vi depending on the timing of the sampling clock sent from a clock generator 3. The timing circuit 4 generates the timing being synchronized with the sampling clock and starts an A/D converter 5 with such signal. Thereby, the A/D converter 5 fetches the sampling value V1 and converts it to a corresponding digital value V(i) and sequentially input them to the processing circuit 6 and stores therein. The processing circuit 6 obtains the average value V(j) and dispersed value E(j) for the digital value V(i) for each period Ngamma corresponding to the continuous specified number N and then stores them.

Then the number of times of out- of-phase is counted by a counter 4 for the output of detection 3. While a reference clock signal (f) is applied to a terminal (b) and then divided 6. Thus accounting time signal (g) is produced and sent to counters 4 and 5 and a holding circuit 9. Then the outputs of counters 4 and 5 are sent to identification circuits 7 and 8 respectively and receive decision whether both counted values exist within the allowance values. Then the outputs of circuits 7 and 8 are supplied to an AND circuit 10 and sent to the circuit 9 after an OR obtained.

Abstract: PROBLEM TO BE SOLVED: To provide a method of press-drawing a metallic plate which can draw the metallic plate of Al alloy plate, etc., having poor formability into a sound formed product without defect of wrinkle, crack, etc., by suitably controlling blank holding force at the time of drawing. SOLUTION: The blank holding force F at the time of drawing is held constant in the range of 1.1FM<=F<=1.6FM in the range of<60% of a total stroke of forming and reduced to a value in the range of 0.5FM<=F<=  (-1.5 S/H)+2.5} FM in the range of 60-90% of the total stroke, and is set to a value in the range of 0.5FM<=F<=0.9FM in the range of >90% of the total stroke to execute the drawing. By this method, the blank holding force is made high during the period from the initial stage to the middle stage of the forming process to restrain the development and the growth of wrinkle and on the other hand, the blank holding force is reduced to the suitable value in the latter period to prevent the development of crack and the remaining of wrinkle caused by excess flowing of the material.  In such a way, the metallic plate having poor formability can be drawn into a complicated shape without developing the wrinkle, crack, etc.
