Title: Correction method for rotational angle and device thereof
Inventor: FURUKAWA HISASHI
IPC: G05D3/12
Filed: 1985-11-08
Abstract: PURPOSE:To correct the rotation of an image rapidly and easily by correcting the scanning direction of the electron beam of an electron microscope according to the rotational angle of a measured object. CONSTITUTION:The neighborhood of a positioning reference 10 is illuminated by a light source 13 and the inclination angle of an orientation flat 21 to the positioning reference 10 is detected by a pair of one-dimensional image sensors 14a, 14b mounted on the both end parts of said positioning reference 10. An angle computing unit 16 feeds out a correction signal correcting the deflection of an electron beam 2 to a deflection controlling part 17 on the basis of the detected values. Deflecting current waveform 25 in Y-direction varies uniformly during one period Ty of Y-direction scanning as shown by broken line in the case with no correction, but in the case with correction by correction signal varies staircasewisely corresponding to one period Tx of X-direction and corrects the scanning direction of the electron beam, thereby correcting the rotation of a pattern image 20 on a screen 19 caused by the rotation of a semiconductor wafer W by an angle theta so that the pattern image may be in parallel state to X-axis and Y-axis.

Filed: 1989-09-26
Abstract: PURPOSE:To prevent the formation of large void and obtain a sintered material having high quality by specifying the particle size distribution of sintering assistant powder used as an additive, especially the distribution at the coarse particle side, in the sintering of a principal ceramic powder. CONSTITUTION:A sintered ceramic is produced by mixing principal ceramic powder with a sintering assistant powder, forming the mixture and calcining the formed product. Sintering assistant powder containing <=5wt.% of particles having particle size of >=10mum is used as the sintering assistant in the above process.

Title: Magnetic driving device and image forming device having the same
Inventor: TSUCHIYA RIICHI
IPC: F16D28/00
Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To prevent excess electric power consumption by detecting an inflection point of an electric current value flowing to a coil when driven by constant voltage, and controlling the ON/OFF ratio of pulse width modulating voltage impressed on the coil on the basis of the electric current value. SOLUTION: A CPU 101 turns on a solenoid in a 100% duty to start to detect an electric current value to judge whether or not an electric current waveform reaches an inflection point. When the electric current waveform does not reach the inflection point, whether or not it is an abnormal electric current is judged, and abnormality is processed. When the electric current waveform reaches the inflection point, required holding power is determined from a expression of [required holding power = suction force of an inflection point + an applying load + an allowance], and next, the duty ratio of pulse width modulating voltage impressed on a coil 105 capable of securing the required holding power is searched from a prestored table, and a solenoid driving signal is outputted.  In an abnormal electric current, abnormality is processed, and when becoming OFF time, a solenoid is turned off to finish processing. Thus, the solenoid and a clutch are driven in the necessary sufficient duty ratio to save power consumption.
