Title: Track recording and reproducing system of rotary magnetic recording medium
Inventor: ITOU HARUO
IPC: G11B5/02
Filed: 1983-07-27
Abstract: PURPOSE:To ensure the sufficient scan with a simple tracking mechanism by using a reproduction head of a large width for a track of a small width and a reproduction head of a small width for a track of a large width respectively for a pair of tracks. CONSTITUTION:Recording heads HA1 and HB1 have recording widths W1 and W2 respectively (W1<W2); while reproduction heads HA2 and HB2 have widths substantially equal to the W2 and W1 respectively. When a pair of tracks are reproduced, the head HA2 of a large width is used for a track of a small width and the head HB2 of a small width for a track of a large width respectively. In such a way, the follow-up performance of the track has a margin. In this way, the sufficient scan is performed with a simple tracking mechanism without using a DC motor nor a tracking servo.

Title: Numerical control method and device for working substrate
Inventor: KAWAMURA MASAHIRO
IPC: B23Q15/00
Filed: 1989-05-31
Abstract: PURPOSE:To always attain working up to a required part in the plate thickness direction by using a value obtained by multiplying the plate thickness found out prior to real working by a previously set required ratio as working depth to execute working on each working position. CONSTITUTION:The upper face position of an X-Y table 2 is previously measured by a position detector 9 and stored in a numerical controller 11. A substrate 13 is set up on the X-Y table 2 and the numerical controller 11 calculates the plate thickness by the upper face position data of the base 21 measured by the position controller 9 and the already stored upper position data of the table 2 and multiplies the calculated value by the previously set required ratio. The numerical controller 11 moves the base 21 on the table 2 in the X and Y axis directions and works a spot facing by using the multiplied value as the working depth while moving a tool 8 in the Z axis direction. Consequently, the generation of defective working due to a change in the plate thickness can be prevented.
Patent JP-H085670-A (JP)
Title: Trigger circuit
Inventor: YAZAKI SEIJI
IPC: H03K5/08
Filed: 1994-06-20
Abstract: PURPOSE:To enhance the noise resistance without sacrifice of trigger sensitivity by varying the hysteresis level based on the level of input signal. CONSTITUTION:An input signal 100a is amplified 1 to produce an output signal 103 which is connected, along with a trigger level signal 102, with the input terminal of a comparator 2a. A trigger signal 101a from the comparator 2a is also connected with a trigger detection circuit 4 and a hysteresis level control signal is connected through a control circuit 5 and a D/A converter 6 with the control terminal of the controller 2a. Under the initial state where the circuit 5 controls the converter 6 to set a high hysteresis level, the signal 103 does not exceed the level and the signal 101a is not outputted and thereby the converter 6 is controlled 5 to lower the level gradually. When the signal 103 exceeds the level, the signal 101a is outputted and detected 4 and then controlled 5 at a constant level. Since the hysteresis level is lower than the signal 103 but higher than the noise under that state, the signal 101a is not subjected to jittering caused by the noise mixed into the signal 103.

Title: Lens position controller for zoom lens
Inventor: HIRASAWA KATAHIDE
IPC: G03B5/00
Filed: 1989-05-30
Abstract: PURPOSE:To eliminate a need to adjust the angle of view and the focus point again at the time of reset operation by storing the lens position and returning a lens to this stored position after reset. CONSTITUTION:Values of zoom and focus counters for a lens 103 and a V lens 102 are stored in a storage element 125 through a bus line 126. It is decided whether the lens 103 is placed in the stored position or not, and the lens 103 is moved to the stored position if it is not placed in this position. The same operation is performed for the lens 102. When both lenses 102 and 103 are returned to stored positions together, the normal camera operation is started. Thus, it is unnecessary to adjust the lens position again though the reset operation is performed during operation, and lenses 102 and 103 are returned to original positions.

Abstract: PURPOSE:To realize a logarithmic amplifier in a MOS integrated circuit, and to reduce a consumption current, by connecting in common each in-phase output of all of the two pairs of differential pairs in a cascade-connected multistage MOS type differential amplifier. CONSTITUTION:The ration W/L of the gate widths W to the gate lengths L of MOS type differential pair of transistors TRT01 driven by current sources I01, I02,...I0n, are set in equal, and the drains of the TRs are connected in common, and the outputs are sequentially cascade-connected. A square full-wave rectifier is formed by setting the W/L of two pairs of MOS type differential pair of TRs T11 and T1k driven by each two of current sources I01, I02,...In, and In+1, as 1/k(k>1), and setting the outputs adversely with each other. Each in-phase output of the two pairs of differential pairs is connected in common. As for the outputs V1-VOUT of the differential pair T01, etc., the outputs from the VOUT to the VIN are saturated sequentially, as increasing an input signal VIN. Therefore, an output current IOUT becomes the sum of a differential current I1=(I1-I2)-(I4-I3), etc., at each stage, by the TRs T10-T60, and a proximate logarithmic characteristic to the signal VIN is given to the IOUT.

Abstract: PURPOSE:To perform an instruction operation whthout failure with a simple operation, by indicating a desired point position and generating new instruction data in case that hands are moved on the basis of already generated robot command data to change the point. CONSTITUTION:When a mode selecting switch is set to the instruction mode and a start button is depressed, a processor DPU reads out the first robot command data RD1 from a data memory DM to a register RGS. Current positions Ra, Za, and Qa of hands are read out from a phase controlling data storage memory APM, and increments DELTAR, DELTAZ, and DELTAtheta are inputted to a pulse distributor PDC. Then, the distributor PDC generates partition pulses RP, ZP, and thetaP and gives them to servo circuits SVR, SVZ, and SV to drive motors MR, MZ, and Mtheta, and thus, current positions are updated. After the movement control due to data RD1, the second data RD2 is read out from the memory DM to the register RGS to move hands.
