Title: Deflecting yoke device
Inventor: MARUTA KOREHISA
IPC: H04N9/28
Filed: 1984-07-06
Abstract: PURPOSE:To improve yield in manufacturing deflecting yoke by arranging correcting coils on both sides of in line arrangement on a deflecting yoke, connecting an end to the middle point of sensitivity resistance consisting of the first and second resistances arranged in series, and connecting another end to the common connecting point of two rectifying diodes, and providing a variable resistance that adjusts current flowing in the correcting coil. CONSTITUTION:When the value of resistance RSXIV of a sensitivity resistance 18 becomes above normal direction voltage VF, current flows in rectifying diodes D1, D2, and pseude parabolic correcting current IC(IC=I1+I2) that conforms with period of vertical deflecting current IV flows to correcting coils 11, 12. Misconvergence YH becomes larger in upper and lower parts of the picture, and even when the amount of correction differs in upper and lower parts of the picture due to dispersion of the cathoderay tube and deflecting yoke, misconvergence YH can be corrected over whole area of the picture by adjusting current flowing in correcting coils 11, 12 separately in upper part and lower part by changing variable resistances 21, 22 provided in the correcting coils 11, 12 of correcting coil devices 6, 7, and good convergence characteristic can be obtained.

Title: Photodetecting member
Inventor: SAITOU KEISHI
IPC: G03G5/082
Filed: 1984-07-09
Abstract: PURPOSE:To provide a photodetecting member which is suitable for formation of an image by using coherent monochromatic light and to facilitate production control by having the photodetecting layer of the multi-layer constitution having at least one photosensitive layer and a surface layer having an antireflection function in a short range on a base. CONSTITUTION:The photodetecting layer of the multi-layer constitution having >=1 photosensitive layers along the slopes of the ruggedness of the base having the rugged shape smaller and gentler than the required resolving power of the device is provided on the base and since the layer thickness of the 2nd layer 602 changes continuously from d5 to d6, the boundary 603 and boundary 604 have an inclination with each other. The coherent light made incident on the very small part (short range) l causes interference at the part l and generates a very small interference fringe pattern. If the boundary 703 between the 1st layer 701 and the 2nd layer 702 and the free surface 704 of the layer 702 are non- parallel with each other, the advancing directions of the reflected light R1 and the exit light R3 with respect to the incident light I0 are different from each other and therefore, the degree of interference decreases as compared with the case in which the boundaries 703 and 704 are parallel.

Filed: 1979-11-02
Abstract: PURPOSE: To keep a differential pressure constant through adjustment of the setting point of a main spring, by keeping the butt point of a ball valve against a spring shoe on the axis of a cylinder.  
     CONSTITUTION: A main spring 29 is pressed by a push rod 30 through a spring shoe 28. An auxiliary spring 33 is set below a spring shoe hat 27 which is not radially displaceable but axially. As the main spring 29 set above the hat 27 is gradually pressed through the spring shoe 28, a ball valve 26 comes in contact with the horicontal bottom of the hat 27 at a point (a) to undergo the spring force. In other words, the hat 27 comes in contact with the ball valve 26, being kept in a position balanced between the main spring 29 and auxiliary spring 33. When the ball valve 26 rises dur to hydraulic pressure, a depression is formed at the contact point (a) to hold the ball valve 26.

Title: Image display device and image switching display method applied to the device
Inventor: ISHIBASHI YASUHIRO
IPC: H04N7/173
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To replace a reproduced image with optional image data at an optional reproduction position of a DVD video image. SOLUTION: A time counter 118 counts an elapsed time from start of reproduction of a DVD video image consisting of MPEG2 streams, and when the count of the time counter 118 reaches a link image insert time set to a time set register 117, a DVD decoder 113 generates an interrupt signal (INT). A DVD reproduction control program 201 in response to the interruption signal replaces image data to be reproduced consisting of the DVD video image with a link image designated by link file information. Since the elapsed time from start of reproduction is used for a trigger to replace the reproduced image in this way, the reproduced image is switched at an optional position independently of a position in the stream in which a command for video switching is imbedded.
