Title: Optical disk device
Inventor: MITANI SHOJI
IPC: G11B7/095
Filed: 1989-05-22
Abstract: PURPOSE:To prevent the deterioration of a recording/reproducing characteristic by providing a reflected light detecting head of an optical disk, a tracking control part, a positioner for placing a head thereon, a positioner position control part, and a positioner processing control signal, and holding the center of a lens right under an object track. CONSTITUTION:When a positioner processing control circuit 23 outputs a control instruction signal (h) to a selecting circuit 24, an output (e) of a filter 21 is inputted to a positioner power amplifier 22 and a rough position control is executed. Subsequently, by a tracking control circuit, a laser beam is brought to position control onto a target track. A tracking error signal (b) passes through a two-stage servo error signal generator 25 and generates a two-stage servo error signal (f). The signal (f) passes through a filter 26 containing a lead lag and generates a signal (g). The control circuit 23 generates a positioner two-stage servo position control instruction to the selecting circuit 24 by the signal (h). By this two-stage servo position control, the center of a lens always comes right under an object track, and the compressibility of the whole also becomes high.

Filed: 1979-10-05
Abstract: PURPOSE:To remove the offset voltage by applying the comparison voltage to both the inputs of the comparator at the time of holding, and holding its output in the capacitor. CONSTITUTION:In case of holding, the low level voltage and the high level voltage are applied to the terminal 52 and the terminal 53, respectively, and since MOSFETs60, 61 and 62, 63 are turned on and off, respectively, the input terminals 64, 65 of the differential amplifier 101 receive an input of the comparison voltage of the terminal 51. As a result, the offset voltage is output as an output of the amplifier 101, and the capacitors 68, 69 are charged with electricity. In case of the operation state, since the high level and the low level are applied to the terminal 52 and the terminal 53, respectively, the input voltage and the comparison voltage are applied to the terminal 64 of the amplifier 101 and the terminal 65, respectively. And the offset voltage is removed by the capacitors 68, 69, and does not appear in the output terminals 55, 54.

Title: Production of mask for integrated circuit
Inventor: OOTSUKA HIROSHI
IPC: G03F1/38
Filed: 1977-10-29
Abstract: PURPOSE: To produce a master mask for LSI chips in a short time by moving a mask chip center or a fiducial mask center in an arbitrary direction to make these centers different from each other.  
     CONSTITUTION: Mask chip 22 is put on glass plate 21, and fiducial mark center 24 is moved against mask chip center 23 in an arbitrary direction to make these centers different from each other. Therefore, since the positional slippage of split chips is beforehand corrected when plural split chips (intermediate negatives) various in chip size are compounded to produce a master mask for LSI chips, the data processing which should be performed at an actual production time can be omitted. Further, mask chip 22 can be arranged in the position where the error peculiar to devices can be eliminated, so that the master mask for LSI chips with a high precision can be produced in a short time.
