Abstract: PURPOSE:To facilitate objective evaluation / comparison in a horizontal contour correction characteristics by drawing an index representing a cross point between a pattern and an optical axis and a linear test pattern including the cross point and orthogonal to a horizontal axis onto a chart face formed by a plane orthogonal to an optical axis of an image pickup device is rotated around a horizontal axis and tilted and matching the focus of the image pickup device with the index. CONSTITUTION:This test chart is used to evaluate a horizontal direction contour characteristics of a display means on which an image obtained by an image pickup device is displayed. Then a chart face 1 is formed by rotating a plane 2 orthogonal to an optical axis Z of the image pickup device around a horizontal axis and then tilted is provided and an index P representing a cross point between an image pattern and the optical axis X and a linear test pattern L including the cross point and orthogonal to the horizontal axis X are drawn on the chairt face 1. Furthermore, a scale is provided on the test pattern L and plural auxiliary patterns G are drawn in parallel with the test pattern L. The horizontal direction contour characteristics is evaluated by matching the focus of the image pickup device with the index P.

Abstract: PURPOSE:To eliminate the generation of peeling refuse, and to fix a coil such as a tap-less coil stably to a printed board by bringing a grindstone into contact with the surface of flat type enamel wire stretched to a block by adequate tension and peeling the insulating film of the flat type enamel wire by the rotary motion of the grindstone. CONSTITUTION:A grindstone 1 is brought into contact with the surface of a flat type enamel wire 31 stretched between moving and standing blocks 3a, 3b by proper tension so that the flat type enamel wire 31 is deflected slightly, and the insulating film of the flat type enamel wire 31 is peeled by the rotary motion of the grindstone 1 and reciprocating motion in the axial direction of the grindstone as required. Accord-to the method, melting refuse and combustion refuse do not adhere, thus mounting and fixing a coil such a tap-less coil to a printed board under a stable state without being disturbed by these melting refuse and combustion refuse.

Abstract: PROBLEM TO BE SOLVED: To provide an imaging system and a synchronizing signal generator capable of frame-synchronizing image signals generated by a plurality of imaging apparatuses in the case of using a plurality of the imaging apparatuses capable of varying a frame rate. SOLUTION: An image signal generating section 11 generates an image signal of a variable speed frame rate imaging image. A signal generation control section 24 drives the image signal generating section 11 and generates imaging setting information IF to allow an output section 15 to generate an image signal frame-synchronized with a generated image signal DVd. The output section 15 inserts the image setting information IF to the generated image signal DVd and outputs the result. When receiving image setting information IFex, the signal generation control section 24 controls drive operations of the image signal generating section 11 on the basis of the image setting information IFex to frame-synchronize the generated image signal with an image signal with a reference variable speed frame rate of a supply source of the image setting information IFex.

Abstract: PROBLEM TO BE SOLVED: To provide an image processor by which the contrast and sharpness of an entire image are enhanced more than heretofore. SOLUTION: An edge of which the change of the pixel value is sharp is kept as it is and input image data S1 is amplified except this edge to emphasize and display the part other than the edge, and thus the contrast and sharpness of the entire image are enhanced mote than heretofore.

Abstract: PROBLEM TO BE SOLVED: To compress a dynamic range with high compressibility by applying a circuit and a method for image processing to, for example, a video camera, an electronic still camera, etc., and effectively avoiding a decrease in contrast feeling and unnatural edge enhancement. SOLUTION: An input image X is smoothed while holding its edge to find a gain correction coefficient G, with which pixel values x(i,j) of the input image X are corrected.

Abstract: PROBLEM TO BE SOLVED: To effectively avoid partial contrast reduction and to correct gradation by applying the image processor and image processing method to image processors such as a television(TV) receiver, a video tape recorder, a TV camera, and a printer. SOLUTION: In the case of correcting a pixel value x (i, j) by generating a correction coefficient g (i, j) in accordance with the judged result r (i, j) of an area including input picture data, the operation is controlled so that the spatial resolution of the correction coefficient g (i, j) is switched in accordance with the pixel value x (i, j) of the picture data. Consequently partial contrast deterioration can be effectively avoided, the gradation can be corrected and a natural contrast can be secured even between adjacent areas.

Abstract: PROBLEM TO BE SOLVED: To transfer a disc surely at a high speed with a high position precision by providing a circuit for turning ON.OFF an electro-magnet and elevating a chuck jig contacted and sucked to the hub of the disc. SOLUTION: A MO disc 3 is positioned and placed on a positioning jig 49. A chuck 2 is turned and stopped on the MO disc 3. Meantime, the electro-magnet 11 of the chuck 2 is not excited (A). The chuck 2 is lowered and a chuck jig 29 is inserted to a hole of the hub 5 of the MO disc 3. The electro-magnet 11 is excited by a control circuit, after delaying a little from the lowering of the chuck 2, in other words, after inserting the chuck jig 29 into the hole of the hub 5 and fixing both insertion. Thereby, a shaft 19 and the chuck jig 29 are excited and the hub 5 is attrached to the chuck jig 29 (B). The chuck 2 rises while attracting the MO disc 3 and thereafter, an arm 21 is rotated and the MO disc 3 is carried out to the outside of an inspection driver (C).

Abstract: PURPOSE:To prevent an end face of a ribbon of a magnetic scale from sharply projecting by arranging a forming process to form a groove in a widthwise direction before a removing process to remove a grasp margin, at a position where the grasp margin of a cut piece is separated. CONSTITUTION:Prior to a process to remove a grasp margin, a groove 2d in a widthwise direction is formed at each of both faces of a position where a grasp margin 2c of a cut piece of ribbon 2 is separated. Therefore, the grasp margin 2c can be cut easily at the removing process without using a tool by bending the grasp margin 2c. Moreover, an end face of the ribbon 2 after being cut is rounded by an amount of the groove 2d. Since the cutting process and the treating process for the groove 2d are conducted simultaneously, the end face of the ribbon 2 is prevented from sharply projecting in this magnetic scale.

Abstract: PURPOSE:To perform stable focus servocontrol by projecting three light beams on a rotor and detecting a focus error signal with a light beam for detecting a Z-phase pulse signal. CONSTITUTION:An A/B-phase pulse signal recording part 7AB and a Z-phase pulse signal recording part 7Z are formed alternately on the signal recording surface of the rotor. One Z-phase pit Pz is formed at only one specific-angle position in the entire periphery of the rotor. Three beam spots Sa, Sb, and Sz projected by an optical system are projected on the recording parts. The light beam Sz projected on the Z-phase pulse signal recording part 7Z is guided to a photodetecting element to detect the focus error signal. This focus error signal is obtained from the Z-phase recording part where no signal is recorded, so the signal is extremely stable.
