Title: Transmitter with preemphasis distortion compensation function and predistortion distortion compensation method for transmitter
Inventor: MIURA RITSU
IPC: H04B1/04
Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To suppress decline of distortion compensation characteristics low and to attain low power consumption by having a control part stop a distortion compensation operation of a distortion compensation operation part at the time of a transmission signal power that does not need distortion compensation in a transmitter with a predistortion distortion compensation circuit. SOLUTION: In a transmitter with a preemphasis distortion compensation circuit, at the time of power of transmission base band signals I and Q that do not need distortion compensation, control of a control part 113 is made to stop a distortion compensation operation of a distortion compensation operation part 105. In this device, if a power of the transmission signal is not a power value that makes input/output characteristics of an amplifier 118 linear, distortion compensation does not need to be executed.  Then, the control part 113 is made to monitor the power value of the transmission signals calculated by the power calculation part 112, the distortion compensation operation is conventionally performed in the case of the power value that needs the distortion compensation, the distortion compensation operation is stopped in the case of the value that does not need the distortion compensation, and the base band signals I and Q are made to be outputted as they are.

Abstract: PROBLEM TO BE SOLVED: To enable flexible inspection by converting RGB value at each point into a coordinate at each corresponding point in a uniform color space and calculating contrast of each point of a color image of an object to be inspected through the use of the coordinate at each corresponding point in the uniform color space. SOLUTION: A color image 2 is converted from a value in an RGB color space being a camera output into a value in an L*a*b* uniform color space in matching with a human sense. A clustering of a reference image is conducted in the L*a*b* uniform color space by the K-average method designating in advance a cluster number and the gravity center of each cluster is obtained. Then the L*a*b* value corresponding to the coordinate of each point in the RGB system color space is calculated and the contrast with respect to the L*a*b* value is calculated, based on the L*a*b* value and the cluster gravity center position. Then the contrast with respect to each coordinate of the RGB system is stored in a lookup table LUT 8. In this inspection processing, the LUT 8 is referenced to the photographed color image of the object to be inspected to obtain the contrast image.

Title: Automatic control device of rolling reduction of roll correcting device
Inventor: OONO YUKIO
IPC: B21D1/05
Filed: 1984-02-20
Abstract: PURPOSE:To improve production efficiency by controlling the rolling reduction of leveling rolls to be constant based on the difference obtained by comparing an actual driving torque with a prescribed torque stored previously. CONSTITUTION:A correcting torque is produced in a driving shaft when a steel sheet is bitten between leveling rolls, and its detected value is transmitted to an operator 25. The correcting torque is compared with a reference torque stored in a storage unit 24 by the operator 25. The deviation of the difference obtained by the comparison of operator 25 is converted into a rolling reduction by a converter 26, and is inputted to an operator 18. A hydraulic cylinder is actuated through a servosystem 19, based on the difference signal between said rolling reduction and a set rolling reduction. New position and torque signals by said actuation are inputted to the operator 18, to perform the control so as to make the total sum of them to be zero. Because the rolling reduction is automatically controlled by this method, the recorrection is not required, and the production efficiency is improved.

Abstract: PURPOSE:To enable the adjustment of the quantity of light with a simple construction by making an optical fiber as a part of a reference light optical path and as a part of a light quantity adjustor. CONSTITUTION:The emission end face 10a of the first optical fiber (OF) 11 is set so as to align the optical axis of the incident end face 11a of the second OF11. A rack section 12a formed on a support base 12 of the OF parallel with the optical axis and a rack section 13a formed on a support base 13 of the OF11 parallel with the optical axis are engaged with a pinion 14 and when the pinion 14 is turned in the direction of the arrow R, for instance, the space between the end face 10a of the OF10 and the end face 11a of the OF11 on the optical axis narrows while when it is turned in the direction of the arrow L, the space expands. This permits light to be attenuated according to the distance between the end face 10a of the OF10 and the end face 11a of the OF11 and enter the end face 11a of the OF. Thus, the radiation light attenuated to a desired value is emitted from the emission end provided at a light receiving section passing through the OF11 and incident on a light receiving section to make a reference light thereby enabling the adjusting of light with a simple construction.

As the result, the need for a half- wave plate, etc., for converting the plane of polarization is eliminated.  The optical pickup with which recording and reproducing are easily and surely executed by a simple constitution is thus obtd.
