Abstract: PROBLEM TO BE SOLVED: To enable APC(automatic power control) over light beams by only one photodetecting means by using an optical detecting means of a write start signal detection system in common. SOLUTION: With a laser forcible turn-on signal UK1 from a CPU 20, a semiconductor laser light source 23 is forced to turn on and once a synchronizing signal BD is detected, a peak holding circuit 31 is placed in a hold state and outputs its detected quantity A to the CPU 20 after A/D conversion. With a laser forcible turn-on signal UK2, a semiconductor laser light source 23b is forced to turn on, and the current output value B of the peak holding circuit 31 is converted by an A/D converter 32 into a digital value a time T later and inputted to the CPU 20. The detected quantities A and B are compared with each other and when A>B, the light emission quantity of the semiconductor laser light source 23b is increased by one stage by increasing a laser driving current setting signal CS, so that the output value B of the holding circuit 31 is found again.  Then, when A <=B, the value of the laser driving current set signal CS is held and the APC operation is finished.

A throttle valve 27 is thus closed. When an intake valve 4 is opened in a first suction stroke and a piston descends, because of the valve 27 being in the closed state, the pressure in an intake air passage becomes negative, and the air in the chamber 6 is fed into a combustion chamber, but only in small quantity. A valve device 31 is opened by the negative pressure in the passage 2, and thus the valve 27 is gradually opened.

Filed: 1996-12-12
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of liquid crystal panels. SOLUTION: When a horizontal synchronizing signal and a vertical one are not inputted or caused to frequency change, a HS detecting circuit 17 outputs an HS discriminating signal to switch a switcher 13 to the side 1.
