Title: Fine movement positioning stage
Inventor: TOMINAGA KAN
IPC: G02B21/26
Filed: 1998-07-01
Abstract: PROBLEM TO BE SOLVED: To inexpensively realize a high-speed and high-accuracy positioning by using a parallel plate spring guide or an elastic fulcrum parallel link guide so that a high-accuracy straight movement may be obtained and using screw driving by a motor so that a large displacement amount may be obtained. SOLUTION: The movement of a screw shaft 42 in the shaft direction is transmitted to a movable part 1 through a thrust ball bearing 7 and a coupling bar 5 and the movable part 1 is moved. The displacement of the movable part 1 in the shaft direction at such a time is guided to a double parallel spring mechanism 3. Because leaf springs 31a and 31b of the same size are symmetrically deformed by an equal amt. and moreover against the center line, the movable part 1 guided to the springs is likely moved straight along the center line. Meanwhile, the shaft runout and the rotation of the shaft 42 which are about 10 μm in maximum, are absorbed by rolling displacement between a thrust plate 72 and a ball 71 and hardly transmitted to the coupling bar 5.  At such a time, the shaft runout and the rotational force caused barely by rolling frictional resistance between the ball 71 and the plate 72 are absorbed by a circumferential notch 52 provided on the bar 5.

Filed: 1996-07-16
Abstract: PROBLEM TO BE SOLVED: To provide a light transmission body which has high luminance and with which the uniform luminance distribution within a light exit surface is obtainable without subjecting the light transmission body to a uniformization treatment of dot patterns, etc., by specifying the average angle of inclination of the light transmission body surface to a specific range and specifying the region where the average angle of inclination is a specific degree or above to a specific ratio or below. SOLUTION: The light transmission body 1 for a surface light source element is constituted by forming the one side end surface of a transparent substrate as a light incident surface and the one surface approximately orthogonal with the light incident surface as the light exit surface. The light exit surface and the one surface of the rear surface thereof are composed of rough surfaces having fine ruggedness. The average angle of inclination of the rough surfaces is 0.5 to 7.5 deg. and the region where the average angle of inclination is >=20 deg. is <=2%. As a result, the emissivity from the light transmission body 1 is lowered so that the exit light from the light transmission body 1 is emitted concentrically in one direction.  A light source 2, such as fluorescent lamp, is arranged at one end of the light transmission body 1 in the surface light source element and a reflection film 4 is formed by a reflection film, etc., on the rear surface facing the light exit surface.

Title: Method for forming tomographic image of specimen by nmr
Inventor: FUJITA AKINORI
IPC: G16H10/60
Filed: 1985-08-23
Abstract: PURPOSE:To obtain the sharp tomographic image of a specimen with high sensitivity, by detecting a noise signal in such a state that magnetic field gradients in X-axis and Y-axis directions are superposed to the time zone between pulses 90-180 deg. to a NMR static magnetic field. CONSTITUTION:The magnetic field gradient 6 in an X-axis direction, the magnetic field gradient 7 in a Y-axis direction and the magnetic field gradient 8 in a Z-axis direction are superposed to a static magnetic field between a 90 deg. pulse 1 and a 180 deg. pulse 2. The spin in the specific cross-sectional layer in a specimen excited by the pulse 1 is disturbed in its phase and not detected as a signal and only a noise signal component is detected. This noise signal component also contains the NMR signal obtained by repeating a NMR signal exciting/detecting sequence preceding to a NMR noise signal exciting/detecting sequence. Therefore, by subtracting the noise signal component from said signal, the noise signal causing the linear noise image in the longitudinal direction is removed and a sharp tomographic signal can be obtained.

Filed: 1990-07-13
Abstract: PURPOSE:To simplify the operation and the mechanism of an automatic pressure control valve together with reduction of the number of troubles by detecting the primary and secondary pressure levels of a valve and calculating the changing rate of the valve opening amount in order to fix the secondary pressure based on the changing rate of the primary pressure if changed. CONSTITUTION:A primary pressure sensor 4 and a secondary pressure sensor 5 are attached at the primary and secondary sides of a valve member 2 respectively and then connected to a control means 6. The means 6 is provided with a valve opening amount which calculates the changing rate of the valve opening based on the values detected by both sensors 4 and 5. The primary and secondary pressure levels detected by both sensors 4 and 5 are measured, and the valve opening amounts are calculated for correction of the changes of both pressure levels if detected. Then the necessary valve opening amount changing rate is outputted so that the opening amount of the member 2 is controlled via an actuator part 3. As a result, the pressure of the secondary side, i.e., a steam using device 10 can be kept at a prescribed level. In such a constitution, the operation and the mechanism can be simplified for an automatic pressure control valve.

Filed: 1986-08-07
Abstract: PURPOSE:To lighten a burden at the time of debugging and to avoid the careless destruction of data during the execution of a program by outputting a signal that indicates the filling up of a stack area provided in a RAM and inhibiting an interrupt process when a stack point reaches the stack level. CONSTITUTION:A zone from the final address of the RAM to an address stored in a stack level SL setting register 6 is set as a stack area 3S. A comparator 7 compares the stack point and stack level SL, and when the stack point arrived at the stack level SL, outputs the signal of high level to the set terminal S of a flip-flop 8. When the stack point arrived at the set stack level, this is detected, and accordingly, the stack level can be changed as necessary at the time of preparing a program and debugging. As interruption is inhibited at the time of execution of a program, the enlarging of the stack area to above set stack area is prevented, and the destruction of data stored in the RAM 3 is avoided.
