Title: Ophthalmological photographing device
Inventor: MIZUOCHI MASAHARU
IPC: A61B3/14
Filed: 1999-01-28
Abstract: PROBLEM TO BE SOLVED: To provide an ophthalmological photographing device capable of surely preserving a fluorescent photographed image as a black-and-white image. SOLUTION: When fluorescent photographing is started, a mode switching signal is sent to an image processing part 31 for processing an eyeground image, the processing mode of the image processing part is converted to a black-and- white processing mode and a timer 35 showing the lapse of time from the dosage of a fluorescent agent is operated. During this timer operation, the fetched eyeground image is converted to a black-and-white image by the image processing part 31, displayed on a monitor 34, stored and preserved in an image storage device 32. Thus, since the image is automatically converted to the black-and-white image when the fluorescent photographing mode is started, separate operation with a mode switching button is not required, switching operation can be prevented from being forgotten or reset and efficient and sure fluorescent photographing is enabled.

Title: Sheet carrier
Inventor: NADA MINORU
IPC: B65H9/00
Filed: 1989-01-31
Abstract: PURPOSE:To correct sheet position by a lateral resist means without interfering with a side standard member by defining predetermined difference between a sheet standard position that is decided by the side standard member and a sheet standard position that is adjusted by the lateral resist means. CONSTITUTION:A side standard member 28 is defined at the position a predetermined amount X farther than a sheet standard position L that is decided corresponding to an image region 10A that is formed on an image holding body 10 of a copying part. In almost all of the cases, positioning is performed in a direction C, and even when a sheet S is positioned in a direction D owing to slanting, etc., the degree of movement is small. Wrinkling or jamming of a sheet due to contradiction between the regulation by the side standard board 28 and the moving direction of a pair of resist rollers 22 (lateral resist means) are thus prevented.

Title: Valve opening and closing control device in internal-combustion engine
Inventor: UENO MASATO
IPC: F01L13/00
Filed: 1983-02-10
Abstract: PURPOSE:To improve fuel consumption by always making it possible to set optimum valve opening time of a suction/exhaust valve irrespective of an engine turning speed while improving a hydraulic tappet structure in a device where the suction/exhaust valve is closed and opened via the operation of the hydraulic tappet sliding on a cam. CONSTITUTION:Discharged oil from a pump is forcedly sent via communication holes 12, 18, 25 to a hydraulic tappet 8 opening and closing a suction/exhaust valve via a push rod 5 and a locker arm while being subjected to elevation force produced by a cam interlocking with engine rotation and supplied to the second and first space parts 23, 20 by opening and closing a check valve 30. In this situation, a body 10 is slowly lifted resisting the first and second springs 21, 29 by means of a cam, for example, during engine running with a low speed, so that much amount of the oil in respective space parts 20, 23 is discharged from an exhaust outlet 13. Accordingly, both a gap A for valve clearance and a gap B for lift loss become zero, followed by the decreased lift amount of the suction/exhaust valve, allowing valve opening time to be shortened.

IPC: B32B33/00
Filed: 1996-02-06
Abstract: PROBLEM TO BE SOLVED: To obtain a sheet whose pattern is variable depending upon a viewing direction at a low cost by providing a pattern with continuously arranged convex lens-like protrusions on the surface of a transparent sheet and printing a pattern with the same continuous pattern as the front face, staggered with the continuous pattern of the front face, on the rear face of the sheet. SOLUTION: Convex lens-like protrusions 21 are provided in a tortoise shell fashion along an arbitrarily selected continuous pattern axis, and a dot pattern 31 with the same continuous pattern axis as the front face of the synthetic resin sheet 1 is printed axially displaced from the continuous pattern axis of the front face, on the rear face of the sheet 1. The convex lens-like protrusions 21 include a hemispherical one, and the pattern 31 may be a polygonal one corresponding to the protrusions 21 in addition to the dot pattern. The alternative for the tortoise shell fashion arrangement of the protrusions 21 and the pattern 31 may be a triangular, a square or a polygonal formation.  As the protrusions 21 gradually become separated from the pattern 31 from a position where these are perfectly laid over each other, the former 21 is remote from the latter 31 and as their separation is further in the progress, the protrusions 21 are overlapped to the adjacent pattern 31.

Title: Code error noise eliminating system for television still picture
Inventor: SASAKI KENICHI
IPC: H04N19/00
Filed: 1978-02-24
Abstract: PURPOSE: To ensure elimination of the noise on the display pictures by giving correction to the code error word while looking at the displayed pictures by the viewer.  
     CONSTITUTION: The viwer, when detecting the noise on the displayed picture, operates keyboard KB to display the luminous point on the picture via index circuit IND. Then the luminous point is put in agreement with the noise position to specify the word having occurrence of the code error, and each bit within the word is altered in sequence based on the words set up by the operation of KB to turn the luminous point incomspicuous on the display screen. Under these conditions, a control is given so that the code error word of still picture memory MEMR may be rewritten with the set word. Through these serial operations, the code error can be corrected at one area. The error code frequency is normally about 10 -6 , and thus the noise is detected at 2 to 3 areas with every display picture. Thus, the noise can be eleiminated through these operations.
