Title: Defect inspecton device
IPC: G01B11/30
Filed: 1992-03-30
Abstract: PURPOSE:To divide a binary image including a plurality of defects into a plurality of regions including a single defect to highly accurately discriminate a shape, type, etc., of the defect for each region. CONSTITUTION:Peripheral distribution information of a binary image A1 is used to divide the binary image A1 into a plurality of regions having a single defect. Here the binary image A1 is desirably an image separated from other regions by painting regions including defective addresses detected by another means with values indicating a defect. The peripheral distribution information is such information wherein the binary image is projected in a sub scanning direction or a main scanning direction, while an independent distributed region having linearity of the peripheral distribution can be divided as a region having a linear defect. By further performing this operation for regions which remain since they have non-linearity, the regions can be further divided.

Title: Liquid crystal display device driving method
Inventor: KO HIDEMASA
IPC: G09G3/36
Filed: 1995-04-27
Abstract: PURPOSE: To make a gradation display and a color display with a high speed and high contrast possible by making a selection time of a row electrode and a means response time of a liquid crystal display element specified values thereby deciding the number of simultaneous selection row electrodes. CONSTITUTION: When the number of simultaneously selected row electrodes is defined to L, the number of all row electrodes to N, the selection time of a row electrode to T, the mean response time of the liquid crystal display element to τ, a fixed rule exists among them. For instance, in the case of the graph taking the selection time T of a row electrode as the axis of abscissa, and the number of simultaneous selection row electrode L50 at the time of showing CR50 as the axis of ordinate, solid lines show τ=0.09 second, and a broken line shows τ=0.23 second. In the case of τ=0.09 second, two kinds of N=490, 245 are shown, and in the case of τ=0.23, the case of N=245 is shown. Then, the L50 is in proportion to the T, and is in inverse proportion to the τ and N. A proportion constant K in the case of L50 =K.N.T/τ becomes nearly 30.  From the matter, the range of the sufficiently small L having the effect of suppressing liquid crystal relaxation is in the case of K=30-300.

Title: Method and apparatus for roll forming of bellows
Inventor: YONEYAMA SHIGEO
IPC: B21H1/00
Filed: 1978-08-29
Abstract: PURPOSE: To roll-form the bellows at high formability and precision, by reducing the pitch between moldings depending on the rolling reduction when a pair of forming rolls approach while rotating.  
     CONSTITUTION: As a roll shaft 22 lowers, moldings 24... are caused to contact with tubular member 1, and are slid into the space between moldings 26... which rotate integrally with a roll shaft 23, tereby forming bellows 2. At this time, simultaneously with the contact mentioned above, the left side molding 26 is moved to the right side under pressure (while the molding 26 at the right end is fixed), and the pitch Pb is reduced depending on the rolling reduction S of the moldings 24... In this case, since the pitch Pa decreases at the same time as the pitch Pb is being reduced, it is possible to form without applying such force that may bring the blanks to breakage. In this method, even when a plurality of bellows 2 are processed simultaneously, the side wall of the member 1 may not be broken by tension, and bellows 2 uniform in both height and pitch may be produced at high efficiency.

The frequency output of the circuit P 2  is applied to the other circuit P 1 , the output frequency of which varies following input frequency and is supplied to the quartz vibrator Q. When the modulation frequency coincides with the resonance frequency of the vibrator, it resonates and the modulation frequency is applied to the circuit P 2 . As a result, the phase fixation closed circuit P 1 , P 2  are fixed at the resonance frequency and the quartz vibrator Q is retained in an resonance. According to this constitution, the piezoelectric vibrator can automatically be caused to resonate and its excitation level can be reduced.
