It is addressed to provide a hydraulic control valve for preventing high-speed rotation of a valve body of a check valve incorporated in the hydraulic control valve of a type that pressure oil is supplied from a tandem, path and a parallel path via the check valve. A check valve unit is constituted by a main unit and a valve body of a first check valve. A throttle is provided on a right side of an O-ring groove. On a main unit side, there is formed a cylindrical housing portion in which a threaded portion is formed on an outer peripheral portion for fixation to a casing of the hydraulic control valve. On an inner peripheral surface of the housing portion, a groove is formed in an axial direction. Meanwhile, the valve body of the first check valve has a rib. At a time of assembly, the rib, is inserted into the groove of the main unit as indicated by an arrow. After the valve body is assembled to the main unit and fixed to the casing, even with imbalance such as phase shift of the pressure-oil path, the rib having fit into the groove, namely the valve body, is prevented to rotate while it is slidable in the axial direction. Thus, the casing of a seating part of the valve body is not abraded.

Moving image correcting circuit for display device

A motion vector difference detection stage detects a difference D in motion vector between a current frame and a succeeding frame and a difference D in motion vector between a preceding frame and current frame. A latched circuit outputs the motion vector S of the inputted current frame as a motion vector S in the case where both of the absolute values of the differences D and D does not exceed a preset value L , and outputs the motion vector S of the frame preceding the corresponding frame as a motion vector S in the case where at least one of the absolute values of the differences D and D exceeds the preset value L . The latched circuit outputs a motion vector of 0 as a motion vector S in the case where both of the absolute values of the differences D and D exceed the preset value L and also the absolute value of the sum of the differences D and D exceeds the preset value L . When a change in motion vector is small, the motion vector of the corresponding frame carries out dynamic image correction. When a change in motion vector is large, the small motion vector of the preceding frame or the motion vector of 0 carries out dynamic image correction.

In a subfield drive method, two subframes of the least brightness are arranged adjacently to each other to select and light up the display device in terms of the change in image brightness in the time axial direction. When, for example, the level of original signal changes from 7 to 8 or from 8 to 7, SF , SF , SF and SF are selected as subframes for level 8, and SF , F and SF are selected as subframes for level 7. This prohibiting any continuous lighting or non-lighting at the levels 7 and 8, there is no substantial change in brightness nor degradation of picture quality at that time. Any distortion of moving image (pseudo contour) is removed by the correction circuit having the frame memory that delays by one frame, the correction constant set circuit that outputs correction data, and the adder that adds the correction data to the original image signal.
