Title: Flip-flop circuit and frequency dividing circuit
Inventor: SUGAWARA MITSUTOSHI
IPC: H03K23/58
Filed: 1981-09-03
Abstract: PURPOSE:To realize a flip-flop circuit which has a function of an inverter in addition to its normal working, by using a control circuit which always sets a circuit of one side under an open state regardless of an input signal. CONSTITUTION:NAND circuits N1 and N2 which function as the 1st circuit containing the input and output connected in a crossed state to each other have an R-S type flip-flop (FF). NAND circuits N3 and N4 are added to the input of the 1st circuit to form a J-K type FF1. Then the output of a gate circuit G1 is connected to the input of the circuit N2 to form a control circuit 2 which sets the circuit N2 under an open state regardless of the input signal. Thus an overall FF circuit is obtained. This FF circuit functions as a normal J-K type FF when the control signal is 0 and then as a mere inverter when the control signal is 1 respectively. Such FF circuits are combined to easily form a variable frequency dividing circuit.

Filed: 1986-06-13
Abstract: PURPOSE:To easily coincide the trapping position of a frequency response characteristic wave with a bulk spurious trapping position by forming a groove at the bottom surface of a surface wave filter, observing the bulk spurious trapping position and next, setting the depth of the groove so that the trapping position and the trapping position of the frequency response characteristic wave can be coincident. CONSTITUTION:First, a damping material 5 is arranged between an input side IDT2 and an output IDT 3 of a surface wave substrate 1 to set a depth (t) of a groove 4 to a suitable value. In this condition, the spurious trapping position of a bulk wave 6 at the position of the output side IDT3 is observed. Next, the damping material 5 is removed and the difference between the bulk spurious trapping position and the frequency response characterisitc wave trapping position is observed. Next, the depth (t) of the groove 4 is determined so that the difference can come to be 0, namely, the bulk spurious trapping position and the frequency response characteristic wave trapping position can be coincident. Thus, the main waveform trapping position can easily coincide with the bulk spurious trapping position.

Title: Tape recorder circuit
Inventor: ITOI TAMOTSU
IPC: G11B5/027
Filed: 1983-07-28
Abstract: PURPOSE:To operate both a pause switch and a fader with operation of a single switch by using a discriminating circuit to discriminate the state of operation for a reproduction switch, a sound record switch or the pause switch and producing the discrimination signal in accordance with said state of switch operation. CONSTITUTION:When a tape recorder is set under a sound recording mode, only a record terminal RE of a logic control circuit 1 is set at level ''0''. Therefore the discrimination signal of an output terminal 6 is set at level ''1'' together with discrimination signals of other output terminals 3-5 set at level ''1'' respectively. When a pause mode is set to stop recording temporarily, both a pause terminal PO and the terminal RE are instantaneously set at ''0''. Thus both input terminals of a gate circuit 30 are set at ''1'' and therefore the discrimination signal of an output terminal 4 is set at ''1''. In this case, a fader pause switch 38 is kept on and therefore a switch element 8 is turned on. Thus the above-mentioned discrimination signal is applied to a fade-out circuit 13.

Abstract: PURPOSE:To prevent the dragging of brake due to air leak in a case in which differential brake control valves causes air leak under the normal travel condition of car wheels not slipping, by discharging leaked air through discharge openings having throttles. CONSTITUTION:A computer 32 decides whether or not right and left drive wheels 12 have slipped by conducting the comparison of the detection outputs of respective wheel sensors 35, 36 for front wheels and rear wheels, and in the case of slippage, a differential brake control valve 37 on a side opposing a drive wheel 12 that has slipped, is opened. Then, air pressure is supplied to a brake chamber 14, and brake is actuated, and the drive wheel 12 that is slipping is braked. At this time, should the above valve 37 cause air leak, compressed air is supplied to the chamber 14 at the time of normal travel, and the dragging of the brake of the drive wheels is caused. So as to cope with this, discharge opening 42 having throttles 41 are provided at air pipings 39. As a result, air is discharged to the outside through discharge openings 42 having throttles 41.

IPC: H04J1/02
Filed: 1978-11-14
Abstract: PURPOSE:To eliminate the crosstalk between the channels of the multi-channel feedback-type amplifier by negating the crosstalk with addition of a simple-structure passive or active circuit. CONSTITUTION:Input sigals v1 and v2 of the multiple channels are applied to channel feedback amplifiers g1 and g2 containing load feedback circuits f1 and f2. When the transmission relation of crosstalk routes K12 and K22 from one channel to another is referred to as K, part of the feedback signal of amplifier g1 of one channel is applied to the input side of amplifier g2 of the other side via branch circuit j12. And one side of the feedback signal of amplifier g2 is applied to the input side of amplifier g1 via branch circuit j21. These circuits j12 and j21 are formed so as to satisfy the transmission functiok of j=[(1+f)g/f, g]K. Thus the crosstalk can be eliminated between channels, where f is the transmission function of the feedback lines of amplifiers g1 and g2, and g is the transmission function of amplifiers g1 and g2 respectively.
