Title: Method and apparatus for measuring backlash of gear
Inventor: ABE MAKOTO
IPC: F16H57/12
Filed: 1987-12-23
Abstract: PURPOSE:To enhance measuring accuracy, by calculating the rotation transmitting accuracies at the times of positive and reverse rotations by an operation apparatus and calculating the backlash between a pair of gears on the basis of the rotation transmitting accuracies at the times of positive and reverse rotations. CONSTITUTION:Gears 8, 13 to be measured are mounted to a meshing tester and the gear 8 on a driving side is rotated in a positive rotary direction. At this time, rotation transmitting accuracy is measured by angle-of-rotation detectors 14, 15. Next, the rotary direction is reversed, and rotation transmitting accuracy is measured in the same way and the difference between both of them is operated to make it possible to continuously calculate the backlash between the gears 8, 13. Herein, in the rotation transmitting accuracies at the times of positive and reverse rotations, rotation transmitting accuracies P1, P2 at the time of the same angle of rotation are inputted to an operation apparatus 16 and backlash is calculated on the basis of the difference P1-P2 thereof. This operation is performed with respect to the angles of rotation corresponding to the combinations of all of gears generated by the meshing of gears. By this method, the measuring accuracy of the backlash of the gear to be measured can be enhanced.

Title: Differential amplifier
Inventor: DENDA AKIRA
IPC: H03K19/0944
Filed: 1988-12-21
Abstract: PURPOSE:To drastically decrease device deterioration caused by the generation of a hot carrier by cross-connecting the electrode of a MOS transistor(TR) where a positive phase signal is inputted and the electrode of the MOS TR where an antiphase is inputted. CONSTITUTION:When an 'L' level is inputted to an input terminal 10 of an ECL logical circuit 20, a P channel MOS TR 3 of a differential amplifying circuit 21 is turned on, and a P channel MOS TR 5 is turned off. Since the drain voltage and gate voltage of an N channel MOS TRs 4 and 6 are surely fixed at a ground potential or a constant current VEE, a condition in which the N channel MOS TRs 4 and 6 are always turned on, is canceled, a factor to generate the hot carrier does not exits, and even when a gate voltage length is shortened, the possibility of the device deterioration is drastically decreased.

Title: Device and method for measuring magnetic resonance phenomenon
Inventor: YOKOGAWA KATANOBU
IPC: G01R33/28
Filed: 1991-12-09
Abstract: PURPOSE:To enable a fine region to be analyzed highly accurately by adding a means for casting light to a sample to be measured and a means for measuring resistivity of the sample to be measured to a magnetic resonance equipment. CONSTITUTION:A cavity resonator 2 is installed between poles of an electromagnet 1 and then a sample 3 to be measured is installed within the cavity resonator 2. A laser beam 4 is introduced through a window of the cavity resonator 2 and is converged at an optical system 5, thus enabling a fine region on a surface of the sample 3 to be irradiated. Furthermore, a micro wave is supplied from a micro wave transmitter 7 to the cavity resonator 2 through a waveguide 6 and then non-paired electrons within the sample 3 are turned into an electron spin resonance state by a magnetic field of the microwave and the electromagnet 1. By casting only a specific region with the laser beam 4, induction of carrier is limited to its neighborhood. Then, by detecting a change in life, etc., of a light-induced carrier accompanied by magnetic resonance phenomenon as a change in resistivity of the sample 3, a magnetic resonance only at the irradiated fine region can be detected highly sensitively and accurately.

Title: Detection part for optical proximity switch
Inventor: FUJIKAWA NOBUMASA
IPC: H01H35/00
Filed: 1998-10-09
Abstract: PROBLEM TO BE SOLVED: To obtain an optical proximity switch which does not cause a malfunction and which can be controlled surely by installing an optical boundary face on which introduced light is confined on only a narrow part used to detect a level. SOLUTION: Boundary faces 1 and a boundary face 2 as optical boundary faces are constituted in such a way that the ratio of the refractive index of a detection-part support 5 to that of a light scattering body 6 is made large or that a mirror face is stuck or that a substance used as a boundary face is sandwiched. Incident light which is incident from a fiber 3 for light introduction travels straight, and it is reflected by the boundary faces 1 and the boundary face 2 so as to be returned to the light scattering body 6. The returned incident light is confiend in the light scattering body 6 by both the boundary faces 1 and the boundary face 2. When it is confiend, the diffusion of the light to a stuck substance is prevented, and a reduction in a quantity of light as a signal, i.e., a noise, can be prevented.  In addition, the area in the diffusion exit of the light to a level can be narrowed. The position of the level can be controlled precisely. The boundary face 2 prevents the simple reflection of the incident light from entering an optical fiber 4 for light reception.

Abstract: PROBLEM TO BE SOLVED: To provide an image processing device which erases the edges of an image, leaving a minimum pixel width suited for the resolution of an image untouched and cuts recording material consumption while improving an image quality. SOLUTION: An image processing circuit 40 has such a function that an edge detection part 41 detects right/left and upper/lower edges in the black area of an image of input image data and outputs the detected results to an AND circuit 43, and a connectivity interpretation part 42 interprets a connectivity when the edge pixels of the input image data are erased at a minimum pixel width set by a minimum pixel width command key 30 and outputs the interpretation results to the AND circuit 43. The AND circuit 43 takes the logical sum of outputs from the edge detection part 41 and the connectivity interpretation part 42 and outputs the conjunction to an AND circuit 44. The AND circuit 44 takes the conjunction of output and input image data in the AND circuit 43 and outputs the logical sum to line memory 15.  That is, when the input image data is a black pixel and the edge detection part 41 interprets it as the edge pixel and the connectivity interpretation part 42 interprets it as a non-connecting point, the image processing circuit 40 outputs a white pixel for the black pixel, and the same image data as the input image data other than the white pixel.

Filed: 1988-12-21
Abstract: PURPOSE:To decrease detection error by memorizing the detection value of a sensor as the standard value when a clamping member is closest to a culm- holding and transferring member and discriminating the thickness of a culm layer based on the difference between the detected value of the sensor and the standard value.

The porous base 3 is provided with an open pore at the side surface part of an outer end and a connection hole inside for permeating a specific gas, and each open pore becomes the introduction part and the unloading part of the fresh air.  When the device is installed in an atmosphere containing the specific gas, the fresh air enters through the open pore of the side surface part of the outer end of the porous base 3, touches the specific gas from the outside of the disk-shaped colored layer 2, and starts discoloration from a circumferential part to a central part. The penetration fresh air is transmitted through the open pore and is unloaded from other open pores, thus detecting gas accurately without being affected by the fresh air.

Title: Charge control circuit for secondary battery
Inventor: TORII YUJI
IPC: H01M10/44
Filed: 1993-12-22
Abstract: PURPOSE:To prevent the charging operation from being interrupted before a secondary battery is fully charged even when the capacitance of a capacitor varies by correcting the variation in the detecting characteristics of battery voltage caused by ambient temperature variation. CONSTITUTION:The voltage being applied to a capacitor 3 is equal to the voltage of a secondary battery 2 minus the forward voltage of a diode 15 and when the ambient temperature of the capacitor 3 rises, the capacitance thereof increases. Consequently, the count required for the voltage of the capacitor 3 to reach a predetermined set level increases but since the forward voltage of the diode 15 decreases due to temperature rise, the count is decreased thus correcting the shift thereof. On the contrary, when the ambient temperature of the capacitor 3 lowers, capacitance of the capacitor 3 decreases to cause decrease of the count but since the forward voltage of the diode 15 increases, the count is increased thus correcting the shift thereof.
