Title: Vertical synchronizing detection system in pcm system recorder-reproducer
Inventor: AOSHIMA SHINJI
IPC: H04N5/10
Filed: 1978-06-13
Abstract: PURPOSE: To readily and rately detect vertical synchronizing by detecting the portion where the rise interval at the last period of the vertical synchronizing pulse period of the composite period signal is extremely narrow.  
     CONSTITUTION: The composite synchronizing signal Sc being applied to input terminal 30 is applied to the clear terminal 37a of a counter 37 through a differentiating circuit 31. A counter 37 maintains the level "H" during the time since the signal Sc rose until the counter counts 16 pulses of 2.0475M Hz, i.e., for a period of 8μ sec. Beyond this the level goes to "L" and the above is repeated. Here, the clear of an FF 38 is released at the rise (time t 1 ) of the final unit pulse PA of the vertical synchronizing pulse period and the inversion output thereofis made "L" so that the data input of an FF 39 is forcefully made "H". When the data are read in at the next rise (time t 2 ) of the signal Sc, the non-inversion output of the FF 39 becomes "H" and the inversion output "L". Such "L" output becomes the vertical synchronizing detection signal.

Title: Optical disk device with focus abnormality detecting function
Inventor: NASU TOSHIYUKI
IPC: G11B7/085
Filed: 1990-03-20
Abstract: PURPOSE:To accurately judge a focus abnormality or the other abnormality at the time of the occurrence of an abnormal state by providing a focus abnormality detector. CONSTITUTION:The distance (focus error) between the focus of laser light passing an objective lens and a disk is detected to lead the focus onto the disk surface. A means is provided which discriminates excess of the focus error detection signal over a prescribed value to output a signal indicating the focus abnormality. That is, the focus abnormality is discriminated if a large deviation of the focus of laser light from the disk surface occurs which cannot occur in the normal focus servo state, and the focus abnormality is detected from the focus error signal. Thus, the focus servo leading-in operation is not performed unless the focus abnormality occurs in the case of the occurrence of the abnormal state, and this operation is performed when the focus abnormality occurs.

Filed: 1990-03-20
Abstract: PURPOSE:To enable detection blow out of a fuse by providing a voltage drop part between a charging power supply part and a fuse and further by providing a switching part. CONSTITUTION:A confirmation signal is outputted by a confirmation signal output part 9 on the basis of the support of an electronic circuit 1. Then, switch 8 is turned ON and the current at a point (c) flows to earth 10. Consequently, the voltage of at point (c) drops from the voltage at the time of charging. When a fuse is blown out, the voltage at a point (b) falls below a predetermined value because the point (b) is not supplied with power from a battery 3. Accordingly, a low-voltage detecting element 6 connected with the point (b) detects that the voltage at the point (b) is lower than the predetermined value. Thus, because the voltage at the point (b) falls below the predetermined value after the confirmation signal has been outputted by the confirmation signal output part 9, the electronic circuit 1 detects that neither the power supply is not interrupted nor any fault occurs in a charging power supply part 4 but the fuse 5 is blown out.
