Filed: 1985-09-20
Abstract: PURPOSE:To reduce switching noise by using a sound signal obtained from the demodulation of an FM signal without phase discontinuity in a switch circuit so as to replace a switching noise generation period. CONSTITUTION:The 2nd FM demodulator 31 demodulates an output signal of the 2nd preamplifier 4 and gives the result to the 2nd switch circuit 32. A magnetic tape 12 wound on the peripheral of a cylinder is wound by >=180 deg. and the FM sound signal reproduced from the 1st, 2nd sound heads 1, 2 is reproduced respectively at the changeover period of a switch circuit 5. In demodulating an output signal of the 2nd preamplifier 4 by the 2nd demodulator 31, the demodulated output is a demodulated output not including spike noise. Further, the timing of the changeover of the 2nd switch circuit 32 is selected so that the phase of the output signal of the 1st and 2nd demodulators 6, 31 is coincident. Thus, the sound signal without noise is outputted at an output terminal 9.

Title: Da converter
Inventor: URAGAMI KEN
IPC: H03M1/08
Filed: 1988-08-20
Abstract: PURPOSE:To attain a high speed and low noise DA converter by arranging the timing of digital signals divided into an in-phase signal and an opposite phase signal constant. CONSTITUTION:Digital input signals Din D0-D3 are are shared into low-order bit signals D0, D1 and high-order bit signals D2, D3 and the low-order bit signals D0, D1 apply current weight not through a decode circuit, while the high-order bit signals D2, D3 apply current weight via the decode circuit 5. Thus, the largest constant current supplied from constant current circuits 2-0-2-4 is selected to be 4I0 being four times the reference current I0. Since the current switched by current switching circuits 3-0-3-4, 3-X is selected to be four times the reference current I0 or over, the production of noise attended with the changeover of a large current is reduced.

Filed: 1991-07-24
Abstract: PURPOSE:To enable efficient multiple programming by changing the use rate of a process allocated to a CPU and suitably controlling the operating velocity of the process to the target operating velocity. CONSTITUTION:When an interruption processing is started at every prescribed time and it is judged (200) that a first program is under execution on the CPU, operating velocity V2 of the first program is calculated (210) and it is judged (220) whether a value (deviation) obtained by subtracting a calculated target operating velocity V1 from the velocity V2 is larger than a prescribed value Va or not. In this case, when the deviation is larger than the prescribed value Va, a signal is outputted to an interruption control part, interruption to the CPU is generated, and control is returned (230) to an operating system. As the result, the first program is turned to an execution enable state, and the other program in the execution enable state is executed. Thus, even while suitably limiting the operating velocity of the first program, the operating velocity of the other program can be prevented from being lowered.
