Title: Image processing method
Inventor: YAMAMOTO KIYOSHI
IPC: G01M11/00
Filed: 1998-07-02
Abstract: PROBLEM TO BE SOLVED: To obtain an image processing method, capable of removing only a low frequency offset component from original image data without losing a low luminance high frequency component by subtracting the luminance values of respective pixels included in smoothed image data obtained after shift processing from the luminance values of pixels, corresponding to the original image data. SOLUTION: An image processor 6 horizontally smoothens each lines of original image data stored in a 1st image memory 6a, uniformly shifts the smoothed image data by a luminance value of 0.5 e.g. and then stores the shifted data in a 2nd image memory 6b. At completing of the line smoothing of all lines, the image data stored in the 2nd memory 6b are smoothed vertically in each of columns of the image data, and the smoothed image data are stored in a 3rd image memory 6c. The luminance values of pixels corresponding to surface smoothed image data are subtracted from the luminance values of respective pixels in the original image data, and difference image data of subtracted results obtained in each pixel are overwritten in the 1st image memory 6a.

Title: Socket for flat package ic
Inventor: ISHIZAKA TAEKO
IPC: H01R33/97
Filed: 1989-07-20
Abstract: PURPOSE:To simplify the work of lead terminal position alignment by tilting a loading surface made in a plane of an elastic material so that one corner is lower than the other three corners and providing the loading surface with stoppers for the position alignment between the lead terminal of a flat package IC and a receiving terminal. CONSTITUTION:A rectangular loading surface 12 having a receiving terminal 15 for receiving a lead terminal 72 of a flat package 70 is constituted with an insulation material 16 having elasticity. One corner of the loading surface 12 is made lower than the other three corners so that the surface 12 is tilted. Stoppers 13 are arranged for position alignment between a lead terminal 72 of the flat package 70 and the receiving terminal 15 on the edge of the lowest corner of the loading surface. As a result, the position alignment between the lead terminal 72 and the receiving terminal 15 is made by simply placing the IC on the loading surface 12 as the IC slides down the surface 12. Thus, the work is simplified.

Title: Driving gear for inchworm motor
Inventor: TAKIZAWA NAOKI
IPC: H02N2/00
Filed: 1988-07-29
Abstract: PURPOSE:To keep a driving gear at high speed and to make it of high resolution by varying the moving momentum in one sequence from the state where a clamp mechanism is fully closed to the next same state at one sequence unit. CONSTITUTION:A driving control circuit of an inchworm motor is composed of a sequence control circuit 1 to control the starting and stopping of the sequential action, an oscillation circuit 2, a ROM 3 into which the data of the driving sequence is written, a counter 4, a buffer 5, and a D/A converter 6. It is also equipped with piezoelectric elements 7, 10 to 11 of the motor, a first-order lag circuit 8 and a linear amplifier 9. As the moving momentum per sequence is decided by the extending quantity of the piezoelectric element 7, the data is written into the ROM 3 so that the output signal to data buses D1 to D6 will change depending upon the contents of a signal S1 to change the moving momentum of the motor. Thus, by setting the moving momentum to be positioned at high resolution for only the moving momentum of the last one sequence related to positioning, the degree of precision is improved.

Title: Steel wire for gas shielded arc welding and its production
Inventor: KATAOKA TOKIHIKO
IPC: B21C3/08
Filed: 1994-08-10
Abstract: PURPOSE:To improve feeding performance by forming a vertical groove of a specific depth in the longitudinal direction of a steel wire for gas shielded arc welding, thereby lowering the bending rigidity in the longitudinal direction of the steel wire and reducing a feeding resistance. CONSTITUTION:In the process of intermediate drawing, annealing, acid cleaning, copper plating and finish drawing on a hot-rolled steel, a vertical groove 2 in a U-shape, V-shape, etc., is imparted in the longitudinal direction to the steel wire 1 which is intermediately drawn by using a roller with a projection in the intermediate drawing process. The groove is further processed into a narrower vertical groove 2 in subsequent drawing with a die; and finally a vertical groove 2 is formed having a depth of 1/10 or more but 1/2 or less of the diameter of the steel wire in its longitudinal direction. In addition, as the shape of the roller with the projection, the A value (W/d), a ratio of the maximum width W over the height (d) of the projection of the U or V shape, is set 0.5 or more but 1.8 or less, and the vertical groove is thereby efficiently formed. Thus, the feeding performance is further improved by impregnating the vertical groove with a lubricant for example.

Filed: 1987-07-30
Abstract: PURPOSE:To reduce the wiring cost of a sensor cable and to precisely record the state alteration of a sensor by distributing and providing input devices inputting a signal from the sensor to the sensor side. CONSTITUTION:By distributing and providing the analogue input devices 3A-3C and the digital input devices 4A-4C closely to the sensors 1A-1C, a sensor cable 2 is shortened.
