Title: Photodetector
Inventor: KIGUCHI MASAO
IPC: H04N1/04
Filed: 1985-02-07
Abstract: PURPOSE:To set automatically a reference value in response to the characteristic of an element by detecting an unsaturated region based on an output of a photodetecting section while changing a supply current current to a light emitting section of a photo sensor and setting the reference value from the result of detection. CONSTITUTION:A sensor output EOUT from a photo sensor 1 comprising a light emitting element 2 and a photodetector 3 is subject to A/D conversion by an A/D converter 4 and fed to a microcomputer 5. The microcomputer 5 lights the light emitting element of the photo sensor under a predetermined standard current value Bm and compares an initial value An of the sensor output with a setting value A (saturation level of photodetector). When An>A, it is discrimi nated that the sensor is saturated, a designated current data is subtracted to obtain a sensor output An-1. When the value (An-An-1 is larger than the prede termined setting value (x), it is discriminated to be in the unsaturated region and the reference value (threshold level) is calculated based on the sensor output An-1 at that time.

Filed: 1986-02-05
Abstract: PURPOSE:To prevent noise from being produced by making link mount V-shaped blocks have elasticity in the longitudinal direction of pins as well as arranging elastic portions for preventing pin mount V-shaped blocks from tilting around the pins. CONSTITUTION:Forming a link mount V-shaped block 5 with a plate spring, its outer end in the radial direction of a pulley is made of a corrugated form in the direction of width of a V-groove of the pulley to set a corrugated plate spring 5a.

Title: Method for controlling width in rolling mill
Inventor: BAN SEIICHI
IPC: B21B37/22
Filed: 1995-01-17
Abstract: PURPOSE: To stable and highly carry out the accurate width control by adding the amount of width deviation to a detected value with a width meter at a stand on the upstream side and executing tension control based on the amount of tension change determined from the amount of width deviation which is obtained by calculation. CONSTITUTION: In a continuous rolling mill which is composed of seven stands, the amount, ΔW7 of width deviation measured with the width meter 31 on the outlet side of the 7th stand is inputted to a finished width deviation transferring/discriminating device 34 and the amount of tension change necessary to remove this deviation is calculated by a specific equation. When the value is between the upper-limit value of tension and the lower-limit value of tension which are decided for discrimination, the amount of width deviation is inputted to an arithmetic unit 33 for the amount of tension change, the amounts of tension change between the 4th and the 7th stands are calculated and tension control is executed.  On the contrary, when the amount of tension change is not smaller than the upper-limit value of tension or not larger than the lower-limit value of tension, tension control is transferred to tension control on the upstream side with the finished width deviation transferring/discriminating device 34, the amounts of tension change between the 1st and the 4th stands are similarly calculated and the tension control is executed. In the above manner, the width control is enabled without being affected by the temp. variation of a rolled stock.

Title: Control signal production method for optical information reproducer
Inventor: OOGOSHI SEIICHI
IPC: G11B7/09
Filed: 1984-02-13
Abstract: PURPOSE:To correct a shift signal contained in a tracking error signal and to improve the feed servo accuracy of an optical pickup head, by correcting the shift component of the tracking error signal after producing the differential signal at a non-pit part of an information track and also controlling the shift of an optical reproduction head with said shift component. CONSTITUTION:The information on an information recording carrier such as an optical disk 1, etc. is detected by an optical reproduction head 2. Some of these detection signals extract output signals via a tracking error detecting circuit 3; while other detection signals extract output signals via a shift detecting circuit 40 respectively. The servo feed control signals are extracted via a phase compensation circuit 42 and an amplifier circuit 43 and drive a head feed mechanism 8. The output signal of the circuit 40 is equal to a differential signal of the signal at a non-pit part of the information track of the disk 1. This differential signal compensates the shift component of the tracking error signal and at the same time is used as a control signal for shift of the head 2. Thus the shift signal produced from each output signal on a photodetecting surface is approximately proportional to a shift amount as far as the shift amount is small. Thus it is possible to always actuate an objective lens at a place near a neutral point by driving with control the mechanism 8 so as to set the tracking error signal at 0.
