Abstract: PURPOSE:To alternately transfer output data from a signal processing circuit to other signal processing circuits by means of simple constitution by alternately leading out outputs from the preceding signal processing circuit to two succeeding signal circuits in response to clock signals to allow the succeeding circuits to execute respective signal processing synchronously with a clock signal and an inverted clock signal. CONSTITUTION:A digital signal processing circuit DSP1 processes an inputted sound signals of two channels and applies sound signals of four channels to a digital signal processing circuit DSP2. The circuit DSP2 stores sound signals to front left and right side speakers FL, FR and rear left and right side speakers RL, RR in series in respective shift registers SR17, 18. A control circuit 25 outputs a signal 2 and an inversed signal 3 in response to a clock signal shown in waveform diagram 1 and a control circuit 25 outputs signals 4, 5 to lines 26, 27. Consequently, the SR17, 18 outputs said sound signals of 4 channels. The sound signals are applied to D/A converters 30, 31.

Abstract: PURPOSE:To realize a rotary head type reproducing device which can always make excellent tracking operations, by preventing a transferring means from resonating without complicating the circuit configuration. CONSTITUTION:Head switching (HSW) signals are supplied to each control terminal by means of analog switches 31 and 32 and these outputs are supplied to a converting element driving circuit through terminals 26A and 26B and used for driving converting elements 3A and 3B.

Filed: 1983-06-14
Abstract: PURPOSE:To trace easily a program and to reduce the load on a programmer by making the operation state of the program visible. CONSTITUTION:Trap signals 4a and 4b are generated only when comparing circuits 3a, 3b compare the contents of a program counter 1 and address search registers 2a and ab, and both are coincident.

Namely, the registers 2a and 2b, comparing circuits 3a and 3b, and FF11 generate the output signal 12 of the FF in combination. The output signal 12 in program operation goes to ''1'' when the program passes the address set in the register 2a, and ''0'' when passing the address set in the register 2b. Program check points 7-10 are set in the registers 2a and 2b, so the state change of the output signal 12 is converted into a graph through a display device or recorder.

Filed: 1998-04-16
Abstract: PROBLEM TO BE SOLVED: To accelerate a manufacture speed and to efficiently perform manufacture by providing a groove in a longitudinal direction on the inner peripheral surface of a segment type groove member. SOLUTION: The groove 42 is provided in the longitudinal direction on the surface on a center member side, that is the inner peripheral surface, of the segment type groove member 40 for constituting a segment type spacer by being SZ twisted around a center member. Appropriate frictional resistance is present between the segment type groove member 40 and the center member. Thus, when the segment type groove member 40 is SZ twisted on the center member and gathered at the time of manufacturing this optical fiber cable, the setting of an angle for inverting an SZ twist head is made smaller than before, the manufacture speed is accelerated for that and the optical fiber cable is more efficiently manufactured. Also, by changing the kind of the groove such as the number of the groove and the width of the groove, etc., the segment type groove members 40 are identified from each other.  Also, even in the case of laying the optical fiber cable in a place incapable of obtaining sufficient brightness, the members 40 are extremely easily identified from each other.
