Title: Optical disk drive device
Inventor: TANAKA NORIO
IPC: G11B7/095
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a polarity switch signal generator capable of stably generating a proper polarity switch signal for inverting the polarity of a tracking error signal. SOLUTION: When an address decoding signal S41 is normal, based on a rotational angle fetched in a capture circuit 35 and indicated by a rotational angle signal S31 in a switch position between a land and a groove, a reference value stored in a reference value storage circuit 37 is updated. Then, in a comparator circuit 32, the reference value stored in the reference value storage circuit 37 is compared with the rotational angle indicated by the rotational angle signal S31, and a polarity switch signal S29 is generated for indicating the necessity of polarity switching if these are coincident with each other.

Title: Image pickup device
Inventor: YASUDA HITOSHI
IPC: G03B13/36
Filed: 1996-04-09
Abstract: PROBLEM TO BE SOLVED: To conduct automatic focusing(AF) without defocusing even when a shutter speed is changed during AF control by restarting forcibly a lens means when an exposure time is changed while focus adjustment is conducted. SOLUTION: When a processing is started, an AF evaluation value is fetched while driving minutely a focus lens 102 through wobbling to judge whether the lens is focused at present or defocused. Then whether or not a shutter speed is changed by a shutter speed changeover switch SW 112 is judged. When a judging result indicates YES, wobbling is conducted again. Thus, even when the AF evaluation value is changed accompanying a change in the shutter speed, since wobbling is tried again, it is prevented that the focus lens 102 is moved in an afocal direction or stopped at an afocal position resulting from mis-discrimination of a focus state.

Title: Analog-digital converter
Inventor: SHIMIZU SHIYOUICHI
IPC: H03K3/2885
Filed: 1983-05-18
Abstract: PURPOSE:To reduce operation delay and speed up operation by making the ratio of currents flowing to the differential transistor (TR) of a latch circuit different from that of currents flowing to the differetial input stage TR of an analog switch circuit. CONSTITUTION:For example, resistances RL1, RL2, and RL3 are so set that RL2+RL3>RL1 and RL1=RL2approx.=RL3, an analog signal Vin is a little bit lower than a reference voltage Vref, and a clock CP is applied to put an amplifying circuit in operation. In this case, a TRsQ11 is on and a TRQ12 are off. Then, a clock -CP is applied, and the latch circuit is driven to turn on a TRQ8, so that base potentials of TRs Q6 and Q15 drop abruptly. The TRQ12, however, is already off, so the operation state is not changed by latch operation. When the input is reverse, the TRQ12 turns on to shorten the time when the output potential of a TRQ14 varies.
