IPC: H02P27/06
Filed: 1983-08-17
Abstract: PURPOSE:To eliminate stalling of a motor by comparing directly a rotating frequency with the output frequency of an inverter via a digital signal, thereby substantially eliminating the delay time when a power source is switched. CONSTITUTION:While an AC motor 2 is operating through a contactor 3b, the contactor 3b is opened, and a contactor 3a is closed. The motor 2 starts free- running at this time point. Then, when the rotating frequency FM of the AC motor reaches the output frequency FINV of the inverter, the output of a digital comparator 11 becomes ''H'', and one input of an AND circuit 10 is set to ''H''. On the other hand, the other input of the AND circuit 10 becomes ''H'' through a contact 30a simultaneously when the contactor 3a is closed. Accordingly, the output VST of the AND circuit 10 becomes ''H'', and the power of the inverter starts being applied to the motor 2.

Abstract: PURPOSE:To enable a discriminating process with high precision by quantitatively extracting only sensor data on the feature part of paper money to be decided regardless of the shifting of the printed pattern of the paper money, etc., and the deviation in the travel line of a read sensor. CONSTITUTION:A part where specific conditions are satisfied in the output signal of the read sensor 4 is extracted as a decision point. For example, the part where ¦XiA-Xialpha¦>(sigmaiA+sigmaialpha)...(1) is satisfied is extracted as the decision point. Where, XiA is the pattern read mean value of (i) points of the paper money A, Xialpha the pattern read mean values of (i) points of the paper money alpha, sigmaiA the standard deviation of XiA, and sigmaialpha the standard deviation of Xialpha. Consequently, the feature part of the paper money 15, etc., can quantitatively and easily be extracted, and highly precise decision making is enabled. Further, only the feature part is regarded as an object of comparison and then necessary and sufficient data for the decision making may be only stored in a ROM 11, whose capacity is therefore saved.

Title: Method for producing resin-coated substrate
Inventor: NIKAIDO MASARU
IPC: B32B37/06
Filed: 1991-06-21
Abstract: PURPOSE:To obtain a resin-coated substrate having a uniform surface condition and a uniform film thickness, by coating the substrate with a polyamic acid varnish, removing a solvent contained in the film by heating the film at specified temperatures, smoothing by heat-pressing the film formed with a heating roller, and thermal-treating the film to convert the polyamic acid into polyimide. CONSTITUTION:A substrate 2 is coated with a polyamic acid varnish, and a solvent contained in the polyamic acid varnish film 1 formed on the substrate 2 is removed by heating the film at temperatures (e.g., 60-120 deg.C) where the polyamic acid can not be converted into polyimide. The residual polyamic acid varnish film 1 is smoothed by heat-pressing the film directly or through a releasing sheet 7 with a heating roller 4. The smoothed polyamic acid varnish film 1 is then converted into a polyimide film by the thermal treatment at temperatures between 120 deg.C and 480 deg.C to form a polyimide covering layer. In this way, a resin-coated substrate having a uniform surface condition and a uniform thickness is obtained.

Since the chip size of the CCD is very reduced, the yield per unit wafer is increased and the CCD unit price is considerably reduced. Since the aperture is reduced to <=1.0mm with respect to the micro lens corresponding to the micro CCD, the fixed focus system can be adopted and an accurate image of less distortion is obtained. Since the number of pictures is set to 10-25/sec. though it is generaly 30/sec., a bright image is obtained regardless of the extremely small aperture.
