Patent JP-H07322667-A (JP)
Title: Drive device
Inventor: KATSUME TOSHIHIRO
IPC: H02P29/00
Filed: 1994-05-25
Abstract: PURPOSE:To prevent a motor means from being malfunctioned by keeping the connection off between a motor drive means and a motor means until a control means is initialized condition after turning on power. CONSTITUTION:When power is turned on, a power supply 3 for control supplies power to a control circuit 5, so that power is supplied to a timer 9, and the timer 9 starts counting. After preset time has passed, the timer 9 sends a signal to a shut-off circuit 8 to release operation. A control signal is outputted to a motor 7 from a power amplifier 6 and the motor 7 is driven. The time from turning on a power switch 2 to the initialization of the control circuit 5 is set as the time which the timer 9 counts. The connection between the power amplifier 6 and the motor 7 is kept off until the initialization is made after turning on power. No unstable control signal is outputted to the motor 7 from the power amplifier 6, so it is thus possible to prevent the motor 7 from being malfunctioned.

Title: Eccentricity correcting device for optical information recording and reproducing device
Inventor: YOSHIKAWA SEIJI
IPC: G11B7/095
Filed: 1985-06-20
Abstract: PURPOSE:To improve the precision of the control signal of an open loop control system by driving a position adjusting means according to outputs of a control signal generating means and a speed detecting means and adjusting the position of a pickup on tracks of a recording medium. CONSTITUTION:A track error signal which controls the motion of an objective 105 is applied to a tracking driver means and an equivalent circuit 110 having frequency characteristics equivalent to a tracking actuator 109, and the movement extent of the objective is obtained from their outputs. A sine wave output generated by a sine wave generating means 11 on the basis of the movement extent of the objective is subtracted from the output signal of the speed detector 119 and the difference is applied to a servo amplifier 112 to drive VCM 104. The speed detector 119 detects the moving speed of a carriage 103 and generates a speed signal on the basis of a scale 120 for detecting the position of the carriage 103. Thus, the tracking of the pickup 102 to a track is improved in precision.

Title: Semiconductor pellet
Inventor: TANAKA KAZUO
IPC: H01L21/301
Filed: 1989-05-29
Abstract: PURPOSE:To eliminate the degradation in the stability of an element caused by an unnecessary P-N junction and improve the yield by a method wherein only first conductivity type impurity is contained in the sectional surface of the scribe region of a semiconductor pellet and the same conductivity type as the conductivity type of a substrate is given to the scribe region. CONSTITUTION:A silicon oxide film 107 is formed on a P-type semiconductor substrate 101 so as to cover a thick oxide film 102, first and second MOS type semiconductor circuits and a passive region. After that, a PSG film 103 with a thickness of 100nm-1000nm and a silicon nitride film 104 with a thickness of 100nm-1000nm are built up as passivation films for element protection. At that time, the silicon oxide film 107 prevents phosphorus from being diffused into silicon of a scribe region as a buffer layer. Then the thick silicon oxide film 102, the PSG film 103 and the silicon nitride film 104 in the scribe region are removed so as to overlap the passive region of the element. With this constitution, the same conductivity type as the conductivity type of the substrate can be given to the end part of a semiconductor pellet.

Title: Automatic accompanying device
Inventor: FUJII HIROMI
IPC: G10H1/36
Filed: 1989-05-29
Abstract: PURPOSE:To suppress the disagreeableness to hear of an ensemble musical performance to the minimum even if there is an error in a melody input position by reading in melody data of a melody store part and performing a melody, unless the melody is inputted in a position where the melody goes in. CONSTITUTION:A musical performance control part 5 reads in successively accompaniment data from an accompaniment data store part 4, and executes an accompaniment musical performance. On the other hand, in a melody input means 1, an acoustic signal is always inputted from the start of the accompaniment musical performance and sent to a melody detecting part 2. In this case, at every one bar, detecting information related to whether a melody is inputted in its bar or not is derived. The musical performance control part 5 collates the melody detecting information with melody position information of the accompaniment data store part 4, while performing the accompaniment, and in the case the melody is not detected, the corresponding melody data is read in from a melody store part 3, and the musical performance of the melody is started together with the accompaniment. In such a way, even in the case a melody input person forgets a position of a melody input, unnaturalness of an ensemble can be reduced.

Title: Joint mechanism and universal arm device using it
Inventor: HATA MASAHIKO
IPC: F16C11/10
Filed: 1994-05-26
Abstract: PURPOSE:To provide such a joint mechanism as freely changing a hinge angle even if an extremely heavy material is mounted on a movable arm top, and maintaining the hinge angle strongly by means of its rigidity when it stops once. CONSTITUTION:Since non-compressible fluid is sealed in a cylinder 17, rotary members 2, 3 are not rotated relatively even if any energizing force is interposed.
