Title: Synchronous motor
Inventor: SUZUKI YASUO
IPC: H02K21/00
Filed: 1979-01-24
Abstract: PURPOSE: To prevent cocking and to expand the range of stable-rotation voltages by arranging a disc-shaped rotor so as to oppose face to face against the magnetic- pole teeth of a stator; and by providing an arc-shaped magnet, which has a length of three magnetic poles of the rotor and whose top and bottom are magnetized, at the location adjacent to the rotor.  
     CONSTITUTION: Multiple-magnetic-pole teeth 2 are formed on the top of a stator 1 which is bent in a U-shape so as to surround a stator coil 13 of a motor, and a disc- shaped permanent magnet rotor 3 is arranged so that it opposes face to face against the magnetic pole teeth 2. At an edge portion 17 of said stator 1, is provided an arc-shaped permanent magnet 10 which has a length corresponds to the three magnetic poles of said rotor 3 and is magnetized in the up-and-down direction. The permanent magnet 10 opposes the rotor 3, but is higher than the rotor 3 by 1mm or more. In this constitution, even though the mechanical loss of the shaft 8 is degraded especially in the case the length of the gap is long or in the high-temperature atmosphere, a magnetic brake can be actuated by the linkage of the magnetic fluxes of the arc-shaped magnet and the magnetic fluxes of the rotor, thereby the cocking can be prevented.

Abstract: PURPOSE:To perform lateral register correction of recording through a simple device by providing a mark detecting means on the downstream of a register roller and feeding a paper sheet on which a lateral register mark extending obliquely in the feeding direction of a paper sheet is written. CONSTITUTION:A simple lateral register mark 14 extending obliquely in the feed direction of a recording paper sheet is written in the predetermined position of a sheet, for example, a recording sheet, such as a copy sheet, and a mark detecting means 12 for detecting the lateral register mark is provided. A time between the passage of the forward end of the recording paper sheet and the passage of the mark is measured by means of a mark detecting means 12 to calculate a difference between the measured time and a preset time, and a lateral register amount is determined according to the difference therebetween.

Title: Foreign-matter inspecting apparatus for semiconductor wafer
Inventor: IKODA MASAMI
IPC: G01N21/93
Filed: 1993-01-21
Abstract: PURPOSE:To improve the accuracy in foreign-matter inspection by using a threshold value, which is to become the foreign-matter judging reference used in the foreign- matter inspection, as the optimum value for every wafer or every chip in the same wafer. CONSTITUTION:Laser is emitted from an laser emitting device 21 on the specified region of a semiconductor wafer 2 on an X-Y stage 11. The reflected light is detected with a reflected light detector 22. The detector 22 outputs the lightness signal having the value corresponding to the irregularities of the wafer surface based on the reflected light. The lightness signal of one chip is stored in a memory device 31. Then, the signal is compared with the lightness signal associated with the same pattern of the neighboring chip. The difference is computed in an operator 32. The difference is compared with a threshold value T in a comparator 34. It is judged that there is a foreign matter when the difference is larger than the threshold value. The processing for setting the threshold value is performed before the foreign-matter inspection. In this processing, the laser is cast on the specified sampling chip on the wafer. Based on the reflected light, a threshold-value setting and storing device 33 determines the threshold value T suitable for this wafer or the threshold value suitable for every chip.

IPC: G03G21/10
Filed: 1990-01-17
Abstract: PURPOSE:To eliminate offset caused by residual toner by providing a magnet near the surface of a photosensitive body and the edge of a blade and changing magnetic field when an image is not formed so that the toner stuck to the back surface of the blade may be separated and drop from a gap. CONSTITUTION:By depressing a copying start button, a motor 29 is turned on and magnetic rollers 22 and 23 rotate in a direction E. Owing to this changed magnetic field, Lorentz's force acts to the toner so that it may separate from the blade 17 and the toner drops in a housing 11 from the gap 30 between the surface 10 of the photosensitive body and the edge 18 of the blade. As soon as the motor 29 is stopped, the blade 17 is brought into contact with the surface 10 and a copying action is performed by rotating the photosensitive body 1 in a direction A. When the copying action is finished and the photosensitive body 1 is stopped, the blade 17 separates from the surface 10 and stands by to prepare for the next copying. The contamination of respective parts caused by the toner which goes round and adheres to the back surface of the blade while performing copying is prevented.

Filed: 1990-01-18
Abstract: PURPOSE:To operate margins of voltage and effective power under present condition of a system by a method wherein the condition of the power system is determined from a measured value containing an error while a P-V curve is operated from the results. CONSTITUTION:A system condition determining means S10 determines a power system condition at first by employing a measured value containing the error of information on the power system 1, which is inputted from an information transmitting device 2-1. A P-V curve operating means S20 changes the total amount of demand imaginarily by employing this result to operate the higher resolution and the lower resolution of a voltage with respect to different total amount of demand. On the other hand, the P-V curve operating means S20 operates the P-V curve by approximating the resolution according to some function. A voltage margin and effective power margin operating means S30 operates and outputs respective margins based on the results. According to this method, the voltage margin and the effective power margin under current system condition can be operated whereby stable power can be supplied even upon sudden change of a load.
