Title: Tracking error detecting method
Inventor: KOYANAI HIROSHI
IPC: G11B5/588
Filed: 1997-09-26
Abstract: PROBLEM TO BE SOLVED: To make it possible to generate a tracking error signal according to measured time without recording servo information by measuring the time from the reference position of the track recorded on a band shaped recording medium by a helical scanning system is detected till a prescribed signal is detected. SOLUTION: Respective times t1-t3 from a reference position ref (PG signal) to respective synchronizing signals #1-#3 SYNC of respective fragments 702-1 to 3 of a data area 701 are measured. Next, the average value th of absolute values Δt1-Δt3 of respective time difference among respective times t1-t3 and theoretical values t01-t03 is calculated. Then, t1+th or t1-th is made to be a tracking error signal by considering that a magnetic head is deviated to an arrow F2 or an arrow F1 according to t1>t01 or t1<t01. Thus, the phase control of a tape running can be controlled with a higher accuracy as compared with the case the phase control of the tape running is performed by detecting a single synchronizing signal.

Title: Method for estimating failed part of sequential circuit
Inventor: ISHIYAMA TOSHIO
IPC: G06F17/50
Filed: 1995-09-14
Abstract: PROBLEM TO BE SOLVED: To estimate a failure propagation terminal state by extracting a combination circuit by performing tracing in both input and output directions of a failure estimation terminal, and repeatedly performing logic estimation and logic simulation for the output boundary terminal of the combination circuit. SOLUTION: First, a failure propagation enable terminal 111 is obtained from a failure estimation terminal 108 by back-tracing. Then, an indefinite value X is given to the failure propagation enable terminal 111 out of the input boundary terminals of a combination circuit and a logic simulation is performed to normal terminals 112 and 112' other than that using an expectation value, thus extracting a total load state in the combination circuit and an indefinite output terminal. Then, the state of the input boundary terminal using an internal node and the indefinite value is estimated in input direction from the output boundary terminal which becomes indefinite output. The state of the output boundary terminal is estimated by an expectation value which is the estimation value, for example, from a later stage.  Then, after determining the state of each node, total failure propagation enable terminal state is estimated from a failure or the failure estimation terminal.

Abstract: PURPOSE:To prevent a printed image from being inclined and contrive a longer useful life by providing at least two detecting means for detecting whether the leading end of a recording paper is fixed at a predetermined position relative to a platen. CONSTITUTION:Optical sensors 11, 12 are provided in correspondence with two notches 10a, 10b formed in a paper gripper 10. The gripper 10 presses a leading end part of a recording paper 1 fed onto a flat part 3a of 8 platen 3. Next, a stepping motor 5 rotates the platen 3 in the direction of an arrow A. At this moment, the sensors 11, 12 detect whether the paper is present, through the notches 10a, 10b of the gripper 10. When the paper 1 is mounted properly, the waveforms of outputs from the sensors 11, 12 are equal to each other. When the paper 1 is mounted in a skewed state, a difference is generated between the waveforms of the outputs from the sensors 11, 12. A controlling circuit 7, upon detecting the difference, indicates that the paper is mounted improperly, and stops the motor 5.

Title: Transfer paper conveying device
Inventor: KATO TOMOKI
IPC: G03G15/14
Filed: 1995-10-11
Abstract: PROBLEM TO BE SOLVED: To effectively prevent a toner image from being in disorder owing to electrostatic discharging when transfer paper is separated from a conveyance belt or approaches another member by electrostatically charging the reverse surface of the transfer paper across the conveyance belt to the opposite polarity from toner. SOLUTION: The transfer paper 2 to which the toner image is transferred is conveyed by a transfer belt 3 and separated from the transfer belt 3 at a 'separation part' to travel to a fixation device. A roller 4A as an electrostatic charging means is applied with a 'DC voltage having an alternating current superposed' from a voltage applying means 9. Since the electrostatic charging means charges the rear face of transfer paper 2 to reverse polarity for the toner 7, the electrostatic charging means 9 applies an 'AC voltage deviated to the positive polarity' to the roller 4a as the electrostatic charging means. When the roller 4A is applied with the voltage, a current flows along the thickness of the transfer belt 3 to charge the reverse surface of the transfer paper 2 to the positive polarity.  The quantity of this electrostatic charging is so set by experimentation that the discharging gap (d) of the separation part becomes small and the toner image is prevented from being in disorder owing to the electrostatic discharging.

Title: Retry control system
Inventor: HASEGAWA YASUSHI
IPC: G06F11/14
Filed: 1990-10-01
Abstract: PURPOSE:To prevent a CPU from stalling repetitively the same instruction by informing a unit of a diagnostic system of the abnormality of an input/output device when no input/output instruction is accepted from a CPU and the wait time is not changed even with the repetitive retries. CONSTITUTION:A CPU 1 recognizes the waiting time held in a register 6 and performs a retry when the time equivalent to the waiting time passed. If a wait answer is returned again under such conditions, the CPU 1 reads the precedent wait time out of a register 5 before the second retry. This wait time is compared with the returned wait answer by a comparator 12. If the value of the returned wait answer is not updated yet, the abnormality of an input/output device 2 is decided. This abnormality of the device 2 is reported to a unit of a diagnostic system via a signal line 11. Thus it is possible to prevent the CPU 1 from stalling repetitively the same instruction.

Abstract: PURPOSE:To enable the speed of the objective lens of an optical pickup which crosses a track to be detected by passing a tracking actuator driving coil signal through a low-pass filter when a track error signal is out of a prescribed threshold level area. CONSTITUTION:When the track error signal of a sine wave state is not in the area within the prescribed positive and negative threshold level by making an on-track level as a center, the high frequency component of tracking actuator driving coil current is removed by the low-pass filter 8 and the relative speed of the objective lens which crosses the track is obtained.
