Title: Magneto-optical memory device
Inventor: FUJI HIROSHI
IPC: G11B11/105
Filed: 1986-03-28
Abstract: PURPOSE:To attain timing control with excellent recording/reproduction/erasure by comparing a positive/negative peak level of a reproducing signal with a reference value, selecting the result of comparison depending on the recording face so as to detect a recorded area. CONSTITUTION:The bias magnetic field in the recording direction is inverted to sides A, B of a recording medium and the polarity of the reproducing signal of the side A is inverted to that of the reproducing signal of the side B. Switching circuits 18, 22, 24 are switched at the reproduction of the side A and the positive peak level of the reproducing signal via a buffer 14 is compared with a reference value corresponding to the side A by a comparator 19. The recorded area is detected by the result of comparison. The recorded area is detected based on the negative peak level as to the side B, and production of an error is prevented due do deviation of synchronizing signals in case of using the synchronizing signal only for the detection by means of the result of detection and the synchronizing signal and the recording/reproduction/erasure is controlled by an excellent timing.

Title: Laser power supply device
Inventor: HORIKAWA FUMIHIRO
IPC: H01S3/092
Filed: 1999-03-18
Abstract: PROBLEM TO BE SOLVED: To set a low simmer current without interrupting the flow of the simmer current due to overshoot of the current. SOLUTION: When a simmer current value set by a current command part 19 is inputted, although a current detection value 11 before lighting up of an excitation lamp 5 is 0, in this case, the input in an upper and lower limits control part 16 reaches the upper limit set value, after a fixed time, because of integration effect of a PI control part 12. The upper and lower limits control part 16 decides such a state, an integration stopping part 17 stops the input in an integrating part 15 and the voltage command 18 is limited to the upper limit set value.  When the excitation lamp 5 lights up by a simmer trigger and the current starts to pass, the current detection value 11 exceeds a set simmer current value in the current command part 10, a negative value is inputted in the PI control part 12 and in the course of time, the input value in the upper and lower limits control part 16 falls short of the upper limit set value. The upper and lower limits control part 16 decides the state and clears the stop of the upper limit and integration and thereafter does not perform processing of upper limit.
