Filed: 1992-09-16
Abstract: PURPOSE:To provide a manufacturing method for optical master disk in which a sharp edge can be obtained by synthesizing plural light beam spots and performing multiple exposure at the time of forming a wide group by the exposure of light beams and also reducing a luminous flux diameter on the pupil surface of the light beams made incident on an objective lens and equalizing a beam width with a wide group width. CONSTITUTION:Laser beams from a polarizing beam splitter 4, that is exposure beams are made incident on the objective lens 5 and converged. At this time, the beams are synthesized so as to overlap the intensity distribution at the two spots and the wide beam width is generated. Then, at the time of generating a stamper provided with the wide group towards the optical recorder, photoresist is applied on a glass plate with a ground surface, is multiple exposed, is developed and a prescribed irregular pattern is generated on the surface of the resist. Thereafter, the pattern is transferred to the surface of a master disk and turned to the stamper by electroforming. Thus, the spot intensity distribution is in an approximately trapezoidal shape and an edge part is vertical to a main surface and is extremely sharp.

Filed: 1994-11-04
Abstract: PURPOSE: To provide a fingerprint sensor which recognizes a fingerprint with high precision even in the case that the fingerprint is indistinct because of a dry finger, a rough skin, or the like. CONSTITUTION: The finger of a person to be examined is put on a reflection face 15a of a prism 15, and an integral value A of its Fourier spectrum and a peak value or an integral value B of the correlation output are calculated. A judgment object value C(=B/A) is calculated where A is the Fourier spectrum integral value of reflected light and B is the peak value or the integral value of the correlation output, and the subject is identified as the person himself in the case of C>SH where SH is a prescribed threshold, but he is judged as another person in the case of C<=SH. There is an individual difference in clearness of reflected light among fingerprints, and the peak quantity of light of autocorrelations is changed by this difference, and therefore, there is a probability of erroneous judgment if the correlation output is compared with a certain threshold merely.  However, an influence of the individual difference in peak quantity of light of autocorrelations is excluded because he is not identified in the case of C<=SH.

Abstract: PROBLEM TO BE SOLVED: To control the voltage fluctuation, which occurs on another peripheral load at the time of ON/OFF of a load, within a prescribed range. SOLUTION: When the switch of a load component 512 is turned on, a current flows from a rated AC power source 510 to a zero cross detecting circuit 520. In the zero cross detecting circuit 520, the zero cross point of a current waveform is detected and inputted to an output control circuit 522. Concerning the output control circuit 522, a thinning pattern is previously selected and by counting the zero cross points, a signal corresponding to this thinning pattern is inputted to an SSR 524. According to the thinning pattern, the SSR 524 repeats conductive and non-conductive states with one cycle of the current waveform as one unit. In the conductive state, the current flows from the rated AC power source 510 to the load component 512.  Thus, the average value of current flowing to the load component 512 is decreased to the prescribed ratio in respect to all the outputs of the rated AC power source 510.

Abstract: PROBLEM TO BE SOLVED: To reduce the size of band memory. SOLUTION: A plotting engine 420 divides a page into series of bands, applies respective plotting commands for bands and plots the section of object in the band in a temporary buffer. In order to plot the object, the plotting engine 420 applies the expansion functions for the color bias of object, the increase of resolution and inverse transformation of dot gain and next applies a dither function to the designated color value or gray scale value of object in the band so as to change the object into a pixel matrix for each binary plane. By applying the dither function, the required size of band buffer memory is sufficiently reduced. The plotting engine 420 transfers the plotted object to a band buffer 440. A color converter changes the band color from the color model of band buffer 440 to printing color model and the image made into band is transmitted to a spooler 265 for printing.
