IPC: G11B15/43
Filed: 1986-03-20
Abstract: PURPOSE:To realize a quick return reproducing state in a short time without requiring a switching operation of device parts for the quick return reproducing state, by providing the first control member for controlling a displacement of the first spring, the second spring, and a band brake by the second spring, and the second control member for controlling the turning of a tension arm. CONSTITUTION:In case of a quick return reproducing state, a band brake 7 remains wound to a supply reel turn table 1. In such a case, the rotation of the supply reel turn table 1 becomes a bitten direction against the band brake 7, therefore, by such biting force, the second spring 8 stretches. Accordingly, the first control member 9 is separated from a wall 12 and winding to the supply reel turn table 1, of the band brake 7 is loosened. In such a case, by providing the spring so that the first control member 9 always remains separated from the wall 12, a quick return reproducing state can be realized without loosening a brake force to the supply reel turn table, of the band brake by turning a tension arm.

Title: Method of controlling temperatures of semiconductor laser
Inventor: SUGIYAMA IWAO
IPC: G05D23/24
Filed: 1988-03-16
Abstract: PURPOSE:To control the temperature of the element of a semiconductor laser with high accuracy even if ambient temperature changes widely by controlling the temperature of a heat sink on the basis of the output of a compensating circuit for cancelling variations of oscillation wavelength of the laser based on data obtained by measuring in advance the variations of the oscillation wavelength at predetermined ambient temperature and a temperature detection signal. CONSTITUTION:The ambient temperature detection signal from an ambient temperature detection means is supplied to a compensating circuit 12, where data corresponding to the ambient temperature is read out from an internal memory 13. This data indicates a variation of oscillation wavelength of a semiconductor laser 1 at a predetermined ambient temperature. That is, the actual temperatures of a heat sink 2 and the semiconductor laser 1 correspond to the oscillation wavelength of the semiconductor laser 1. Thus, the detection error of a temperature detection element 10 can be known indirectly from the variation of the oscillation wavelength. A compensating circuit 12 generates a control signal of a value cancelling the variation of the oscillation wavelength from this data, and supplies it to a temperature controller 14. The output signal of the temperature controller 14 causes a heater 5 to operate at a predetermined amount of heat corresponding to the value. As a result of this, temperatures of the semiconductor laser 1 can be controlled without scarcely being affected by the variations of ambient temperatures.

Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To realize multiplexing depending on priority without disturbing input sequence according to a definite clock and timing even when plural digital signals processed as packets are received by different bit rates and different clock signals. SOLUTION: Plural digital signals processed as packets are received by different bit rates and different clock signals, the plural digital signals are multiplexed and outputted by the same clock signal. A priority control section 13 places priority on buffer memories 11a-11d to provide an output by the same clock and on plural received packets. An output control section 14 multiplexes the packets based on the priority and provides an output of them so as to prevent received packet transmission order from being reversed. Memory control sections 12a-12d delay the transmission of input packets so that no overflow takes place in the buffer memories 11a-11d and provide an output of packets depending on the priority.
