Title: Disk reproducing apparatus
Inventor: SHIMIZU YASUNARI
IPC: G11B20/18
Filed: 1993-05-26
Abstract: PURPOSE:To improve the reliability of data recorded in a disk by comparing the amplitudes of the regenerated signals corresponding to a maximum modulating frequency pattern part and data part, which are recorded in the disk, and detecting the defects of the reproduced data signals. CONSTITUTION:A gate circuit 36 detects and outputs an amplitude P1 of the regenerated signal of a reference field VFO3 for PLL in a signal amplitude level signal S3 based on a gate signal S1. The level of the amplitude P1 is stabilized by an LPF 42 and supplied into a threshold-level reproducing circuit 38. The circuit 38 supplies a signal Pth, which is obtained by subtracting a constant voltage from the amplitude P1, into a comparator circuit 39. Meanwhile, a gate circuit 37 extracts a data signal amplitude P2 in the signal S3 based on a gate signal S2 and supplies the amplitude P2 into the circuit 39. The circuit 39 detects a part, which is lower than the level of the signal Pth, in the signal S3 in the generating section of the signal S2 as a defective amplitude P3 and outputs a detected defect signal Sd corresponding to P3. Thus, the reliability of the data recorded in the disk is improved.

Title: Image display device
Inventor: SHIMIZU AKIRA
IPC: H04N5/21
Filed: 1996-05-20
Abstract: PROBLEM TO BE SOLVED: To display a black image by masking data including noise when no video signal is received. SOLUTION: A synchronization detection section 6 detects 'presence' or 'absence' state of the input video signal by detecting a synchronizing signal of an input video signal. In the case of detecting the 'presence', a gate section 3 passes data read from a frame memory 2 and the data are fed to a next stage signal processing section 4. In the case of detecting the 'absence', full black screen data resulting from masking data read from the frame memory 2 by the gate section 3 are obtained. Furthermore, for example, the similar effect is obtained even in the case of three systems receiving R, G, B signals.

Title: Filter circuit device
Inventor: NAGAI JIYOUJI
IPC: H03H7/38
Filed: 1982-07-16
Abstract: PURPOSE:To ensure the stable working despite the impedance variation of a varactor element that is used to vary the attenuation characteristics of a filter, by using a coplanar line to filter circuit to obtain a constant impedance. CONSTITUTION:A coplanar transmission line is formed with a center conductor 17 on the same level as a dielectric substrate 16 and earth conductors 18 printed at both sides of the conductor 17 with a prescribed space. In such a case where the conductors 18 are set on the same level as the conductor 17, the characteristic impedance is equal to a fixed impedance value which is decided by a ratio between a1 and b1 as long as the effective dielectric constant including the substrate 16 is constant. Therefore the impedance of the transmission line itself has no variation despite the impedance variation of a variable capacity element 13 which varies the attenuation characteristics of a filter. This can maintain good filter characteristics.

Abstract: PURPOSE:To prevent a latchup from occurring by forming a well for preventing the latchup between a plurality of separated and insulated wells, and applying the lowest or highest potential therebetween. CONSTITUTION:A P-well region 20 for preventing a latchup separated from P-well regions 2, 13 is connected through a P<+> type region 19 with a negative power source VSS. Thus, when the energizing order of the power sources is GND, VSS, VDD, the GND is first connected and then the power source VSS is connected. Then, an N-type semiconductor substrate 1 is reduced to a negative potential by the junction capacity between the region 2 and an N-type semiconductor substrate 1. Thus, a forward voltage is applied to the region 13 and the substrate 1, and holes generated from the region 13 pass the substrate 1. Since a P-type well region 20 connected with the power source VSS is presented, the holes are implanted to the region 20 to remarkably reduce the holes which arrive at the region 2.
