Filed: 1993-09-22
Abstract: PURPOSE:To obtain an optical head device whose access speed is high and which can precisely detect the deviation of a track. CONSTITUTION:A reflected laser beam returned from before position of the recording surface of an optical disk by a half mirror 32 is detected by a first optical detector 40 detecting the deviation of a distance between an objective lens 22 and the optical disk by using one light beam out of the light beams separated through a half mirror 36 and a second optical detector 42 detecting the deviation of the light beam transmitted along the optical axis of the lens 22 and the track of the optical disk by using the other light beam. Thus, an offset component corresponding to the deviation of the angle of a galvano mirror 30 is eliminated and the intensity of the light beam generated from a laser 22 is controlled.

Title: Demodulator, demodulation method and provision medium
Inventor: NAKAGAWA TOSHIYUKI
IPC: H03M7/14
Filed: 1998-08-24
Abstract: PROBLEM TO BE SOLVED: To reduce error propagation with simpler constitution for demodulation by detecting a code stream which does not keep a minimum run and correcting errors based on codes before and after the code string, when a bit shift error is generated. SOLUTION: When signals transmitted from a transmission line or the signals reproduced from this recording medium are Non-Return-to-Zero Inversion(NRZI) modulated (level codes), a comparison part 11 in this demodulator turns binarized data to inverse NRZI codes (edge codes) further. The comparison part 11 also removes a part unrelated to data such as synchronization signals inserted after demodulation to a channel bit stream is performed. A run error correction part 12 detects the error generated near the minimum run and a maximum run from a binarized (edge coded) data stream and performs correction, and a demodulation part 13 demodulates the code stream to the data based on a demodulation table (inverse conversion table).

Filed: 1988-09-20
Abstract: PURPOSE:To simplify a circuit and to prevent malfunction from being generated on the basis of a marker by providing a marker generating means to generate the marker, with which the signal of a single frequency is repeated several time respectively with different the width, and a marker discriminating means. CONSTITUTION:A marker generating circuit 10 generates the signal of the single frequency respectively by the times of T1, T2 and T3 at prescribed intervals and pulses, whose time width is the T1, T2 and T3, are generated by a pulse generating circuit 14 with receiving the marker which is reproduced from a tape 1. A data input means 101 operates also as the marker discriminating means and detects the marker on the basis of a signal from the circuit 14. Namely, the means 101 counts the pulse width of the pulse from the circuit 14 and discriminates whether the sequence of this pulse width is the T1, T2 and T3 or not. When the sequence is the T1, T2 and T3, the signal to detect the marker is outputted to a data discriminating means 102. The marker is recorded before and after the sound information of the tape 1. Then, since the marker is detected at the time of reproducing, and sending of the sound information or stop of the tape is controlled, the circuit is simplified and the malfunction based on the marker can be prevented.

Title: Knock-out device
Inventor: KUREBAYASHI MASARU
IPC: B22D29/04
Filed: 1987-09-21
Abstract: PURPOSE:To disperse a knock-out load to the part to be pressed and to prevent the flaw generation of the formed face of a formed body by bringing an annular pressing member into contact with the part to be pressed at each surface. CONSTITUTION:In case of knock-out of the wheel H used for a vehicle, etc., a horizontal die 6 is first opened to remove an upper die 3 from a lower die 5. At this time the rim flange 7 of the wheel H for rolling stocks is projecting to the horizontal direction. The wheel H for vehicle is then moved to the upper part with fitting it to the upper die 3 to push down a guide plate 9 and an annular pressing member 9 by driving an operation means 84. This annular pressing member 9 presses the rim flange 7 of the wheel H in the lower direction, so the wheel H falls by slipping out of the upper die 3. Due to the annular pressing member 9 being brought into contact with the rim flange 7 at each surface the knock-out load of the annular pressing member 9 is dispersed to the rim flange 7 of the flange H for vehicle, hence a flaw is difficult to cause on the formed face of the wheel H.
