Title: Servo error detecting method for optical disk
Inventor: SEGAWA HIDEKI
IPC: G11B21/10
Filed: 1988-03-14
Abstract: PURPOSE:To improve data reading probability at the time of reproduction by reading address information on the sector following a target sector when a recording or reproducing action is carried out to the target sector and detecting a servo error according to a fact whether said address information can be read within a fixed time or not. CONSTITUTION:An off-track check is carried out at the time of prereading in a write mode and at the same time the address information on an address part 7 following a target sector where data is written is also read. In case the correct address of the next sector is not read within a fixed time when the address of the next sector is received, it is decided that an off-track state may possibly be produced in the relevant sector. Thus no writing action is carried out. As a result, the off-track state can be decided with check of the address of the next sector even in case no off-track state is detected out of the tracking error signal due to the erasion of a guide groove 4, for example, etc. Thus the data reading probability is improved.

Title: Writing method for optical disk
Inventor: SEGAWA HIDEKI
IPC: G11B7/00
Filed: 1988-03-14
Abstract: PURPOSE:To improve the reliability of the information on a flag part by setting the laser output in plural steps within the same sector when the data are written to an optical disk and increasing the laser output set when the data are written to a data part in a sector compared with the laser output set when the data are written to a flag part in the sector. CONSTITUTION:The laser output is set in plural steps, e.g., two steps in the same sector when the data are written to an optical disk. These set steps are freely switched with each other. The writing power for a flag pit 5 of a flag part 2 is increased compared with the writing power the recording pit of a data part 3 for recording. In other words, the writing power is properly set at the part 3 so that the jitter is minimized and then at the part 2 so that the amplitude of the pit 5 is increased enough. Thus, it is possible to reproduce the sector control information and the record information on the part 3 with high reliability via the pit 5.

Title: Frame phase synchronizing circuit
Inventor: KUBO KAZUO
IPC: H04J3/06
Filed: 1991-03-25
Abstract: PURPOSE:To attain frame phase synchronization of a sub-frame signal even when a sub-frame signal in a transmission frame signal is subject to n- multiplexing in an optional relative phase with respect to a transmission frame phase. CONSTITUTION:A sub-frame type identification circuit 10 identifies a type of a sub-frame subject to n-multiplexing in a transmission frame based on a specific pattern of an address written in an overhead area. Then in the case of n=1, a selector circuit 11a selecting (n-1) sets of write addresses and a selector circuit 11b selecting (n-1) sets of read addresses are controlled so that a buffer memory 4 is controlled in common. In the case of n>=2, the selector circuits 11a, 11b are controlled so that the buffer memory 4 is controlled independently for each sub-frame. Thus, frame phase synchronization is taken while being automatically made correspondent even in any of the cases n=1, n>=2 in n-multiplex of the sub-frame signal in the transmission frame signal.

Filed: 1981-04-21
Abstract: PURPOSE:To obtain a precise resistance ratio by a method wherein a pair of resistor elements with their conductivity type reverse to that of the substrate is closely, parallelly arranged on the substrate. CONSTITUTION:On a semiconductor substrate 1 of either conductivity type, resistor elements R1-R4 are formed with their conductivity type reverse to that of the substrate 1. Stress in the substrate 1 caused by resin sealing thereof results in a piezoresistance effect causing changes in the value of resistance. The components in the directions X and Y are the largest at the central part of the substrate 1 where the components in the oblique directions are small. Parallelly, closely arranging in the same direction of a split resistor or a plurality of resistor elements R1 and R2 with the distance between them as small (8-30mu) as possible results in a smaller change in the ratio of values of R1 and R2 and the resistance ratio can be improved as regards precision.

Title: Address control circuit
Inventor: EGUCHI FUMIO
IPC: G11C11/406
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To suppress the increasing of power consumption and the lowering of a data transfer rate to munimums by refreshing all memory cells by a refresh address signal generated by a refresh address counter at the time data of addresses counter become discontinuous. SOLUTION: While an address discontinuity detecting circuit 15 detects that the count-up of addresses of a address counter is continuous, all memory cells are refreshed by actual addresses. Only when the circuit 15 detects the discontinuity of the addresses, while an address makes one round from this a discontinuous point, the RAS-only refresh multiplexed to actual addresses is performed. Thus, the standby time of the real addresses due to a refreshing operation becomes unnecessary and the data transfer rate having good efficiency is realized and the increasing of power consumption is suppressed to a minimum.

Abstract: PURPOSE:To use one fixture for printed wiring boards which differ in thickness in common by providing plural couples of lock claws of different size for prevention against falling and setting lock holes for proper printed wiring boards. CONSTITUTION:A couple of elastic lock claws 11 for a printed board with a 1.6mm. thickness and a couple of elastic lock claws 12 for a printed wiring board with a 1.0mm. thickness are provided on respective diagonals of the bottom surface of the fixture. Lock holes 11a corresponding to the lock claws 11 are formed to enough size for the clock claws 11 to operate effectively. Lock holes 12a, however, are bored to size larger than the proper size of the lock claws 12 as what is called an unloaded hole, so the bar antenna fixture is fixed temporarily with the lock claws 11. Similarly, the lock holes 11b are unloaded holes for the 1.0mm. thickness printed wiring board, and the fixture is fixed with the lock claws 12 for the lock holes 12b.

Therefore, the detection output is increased without increasing the signal-to-noise ratio of the demodulator excessively.
