Title: Image processor and its image display method, and picture element calculating method for display image
Inventor: HIRAMOTO KATSUTOSHI
IPC: G06T15/00
Filed: 1990-11-28
Abstract: PURPOSE:To eliminate the calculation time for an unnecessary area by calculating and displaying picture element data spirally about an aimed point that an operator specifies or preferentially in a necessary area. CONSTITUTION:When the operator inputs the aimed point, its data is inputted and stored in a main storage, and the path of the calculation of the picture element data is determined according to the aimed point data. For this calculation and display, only the necessary area including the aimed point is given priority to other areas and what path in the necessary area is employed for the calculation is freely determined. In this case, a spiral path which spreads centering on the aimed point is defined and the necessary area expands centering on the aimed point as the calculation is advanced along the spiral path. When the spiral path is determined, its data is stored in the main storage or an auxiliary storage device. Consequently, the time of operator's trial-and-error can be shortened.

Abstract: PURPOSE:To guide an idle ring to a cutting scalpel part without fail, to make a cutting length exact and to sew the idle ring into an edge sewing stitch on the back of cloth without fail by pressing an idle ring holding pin to a cloth stand when the cloth is set to the cloth stand, strongly crimping the idle ring between a groove and the idle ring holding pin and guiding the idle ring by the groove and idle ring holding pin when an idle ring holding stand is moved in order to cut the idle ring. CONSTITUTION:In a condition that cloth 35 is set, for the idle ring holding device of an edge sewing machine, an idle ring holding and pressing pin 38 elastically suppressed by a spring 39 presses an idle ring holding pin 12 against the spring 11 and accordingly, an idle ring 37 is pressed, fixed in an enlarged head part between a groove 15 and idle ring holding pin 12 on an idle ring holding stand 16 and is not protruded out. When the idle ring holding stand 16 is moved in a right direction in order to cut the idle ring, the idle ring 37 is separated from the enlarged head part of the idle ring holding pin 12, however, it is still held in the groove 15. Then, even when the idle ring 37 tries to detach from the groove 15, the idle ring 37 is not easily moved since the enlarged head part of the idle ring holding pin 12 is positioned in the side direction of the groove 15. Thus, the idle ring 37 is cut without fail.

Title: Magnetic head for perpendicular magnetic recording
Inventor: SAITO MAKOTO
IPC: G11B5/187
Filed: 1995-12-13
Abstract: PROBLEM TO BE SOLVED: To secure the optimum floating amount of a slider by constituting the middle part of the air bearing surface of the slider without being directly in contact with a magnetic recording medium. SOLUTION: In this magnetic head for perpendicular magnetic recording, the difference of thermal expansion coefficient between a slider material and a gimbal material is made negative (the thermal expansion coefficient of the slider 24 is larger than that of the gimbal 22). Consequently, the slider 25 is stuck to the gimbal 22 by thermosetting resin, the shape of the slider 24 becomes concave shape not convex and low floating amount is obtained. Since the slider 24 is deformed to a recessed shape and an electromagnetic conversion element is simultaneously provided in the end part on the side of the ABS surface (air bearing surface) of the slider 24, the air gap between it and the magnetic recording medium 10 is decreased and magnetic recording is highly densified.

Title: Optical switch
Inventor: NAKAMURA SHIGERU
IPC: G02F1/35
Filed: 1998-11-16
Abstract: PROBLEM TO BE SOLVED: To realize high extinction ratio optical switch operation by a control beam pulse of low energy in an optical switch using a signal beam frequency shift accompanying a resonance excitation nonlinear optical effect in a semiconductor. SOLUTION: A signal beam pulse of a frequency ω1 and the control beam pulse of the frequency ω0 are inputted to a nonlinear optical waveguide 1. At this time, control beam pulse width is set in a value smaller than signal beam pulse width. The optical waveguide part of the nonlinear optical waveguide 1 consists of a nonlinear optical medium showing a nonlinear refractive index change by the absorption or the amplification of the control beam. The frequency ω1 of the signal beam is set in the transparent area of the nonlinear optical waveguide 1. When the frequency ω0 of the control beam is set in the absorption area of the nonlinear optical waveguide 1, a frequency shift to a high frequency side occurs in a part of the signal beam pulse made incident together with the control beam.  An optical frequency filter 2 outputs only a component that the frequency is shifted. Thus, the optical switch operation by the control beam pulse of the low energy is realized.
