Filed: 1984-01-23
Abstract: PURPOSE:To prevent a motor from the generation of noise by providing an exclusive OR circuit generating ''no output'' for a zero output from an inversion circuit, so that no voltage is applied to the motor. CONSTITUTION:An output from a triangular wave generating circuit 3 is supplied to the positive side input terminal of a voltage comparator Q3 and the negative side input terminal of an operational amplifier Q5, a triangular wave from the Q5 is supplied to the negative side input terminal of a voltage comparator Q4 and the output of an operational amplifier Q1 is supplied to the negative and positive side input terminals of the comparators Q3, Q4 respectively. The waveforms obtained by the comparators Q3, Q4 under the positive and negative voltages of the output from an operational amplifier Q1 are inputted to an exclusive ORQ6 and shaped in the same waveform. On the other hand, the positive and negative voltage outputted from the amplifier Q1 are applied to a power amplifier 2 through a polarity switching circuit 5 and a motor 1 is rotated clockwise and counterclockwise. When the input/output of the amplifier Q1 is 0V, the waveform obtained by the comparator Q4 is inputted to the ORQ6 and turned to zero output, so that no voltage is applied to the motor 1.

IPC: G06T7/00
Filed: 1987-01-16
Abstract: PURPOSE:To extract an object picture such as a character or the like sharply at a high speed even from a complicated picture or even under the environment where uneven lightness is fluctuated for 1min to the next by applying arithmetic calculation between a background picture and a picture being object of processing. CONSTITUTION:Figure gA is a figure indicating only one line A-A' of figure fg showing an input picture, with the position as the X axis and the lightness as the Y axis. A filter is provided for three picture elements f1-f3 to process the relation of mix (fi)i=1-3 and to write the result to the position of the element f2. In applying the processing above to all picture elements, Figure gA<(>A<)> is obtained in which the lightness of the data is increased. Let the character width be 5 picture elements, then the dark portion of a character is replaced completely into the surrounding background picture data in repeating the said processing thrice and the background picture is generated easily. In taking a difference between the picture shown in figure gA<(3)> and the Figure gA, the character part only is made sharp and the object picture is extracted.

Title: Nonvolatile semiconductor storage device
Inventor: IBA TOMOHISA
IPC: G11C17/00
Filed: 1995-01-24
Abstract: PURPOSE: To make it easy to turn on a memory cell of which erasure is insufficient and to suppress increase in the number of erase pulses, by counting the number of the erase pulses for an erasing operation and by making the voltage value of erase verify voltage higher than an ordinary value when the counted number exceeds a prescribed value. CONSTITUTION: An erase verify voltage is given to an X decoder 4 and a Y decoder 5 from a verify voltage generating circuit 26 so as to check up whether erasure has been completed or not. In the case where the erasure is determined as insufficient, a command decoder 13 generates an erase pulse again and an erasing operation is executed again. An erase pulse counter 27 counts up sequentially the number of the erase pulses generated by this command decoder 13. When the number of times of this erasing operation exceeds a number set beforehand, the counter 27 makes an output and delivers it to the verify voltage generating circuit 26. Thereby, a transfer gate 29 is turned on, a memory cell is turned on and a current flows from a bit line 21 to a source line 25. Accordingly, the effect of suppressing increase in the number of the erase pulses is produced.

Abstract: PURPOSE:To send a pi/4 DQPSK modulation signal from a mobile station with less information quantity to an error correction decoder of an exchange station without deterioration in quality by applying soft discrimination demodulation to the pi/4 DQPSK modulation signal at a base station of the mobile communication system. CONSTITUTION:A reception signal is subject to quadrature detection by a detector 1-2, I, Q signals are given to a sample-and-hold circuit 1-3 in which sampling- quantization and soft discrimination are executed in 8-bit in a symbol timing and an average level calculation device 1-4 obtains an average signal level for each transmission unit based on the output. A table 1-8 is referenced from the average signal level to decide a quantization range constant and an adjustment device 1-6 adjusts the quantization range and level for soft discrimination information based on the range constant so that the quantization range is narrower and the level is smaller as the average level is smaller. A compressor 1-7 extracts only a changing bit range (e.g. high-order 4-bit) based on the adjusted soft discrimination information and the result is sent to an exchange station.

Title: Image display device of electron microscope
Inventor: OIKAWA TETSUO
IPC: H01J37/22
Filed: 1990-01-18
Abstract: PURPOSE:To project a high precision electron beam image on a display by setting the motion positions in dynamic range of two photo-electric booster tube in different positions so that all beams of light emitted from an accumulative fluorescent substance sheet can be sensed. CONSTITUTION:Electrons having penetrated a specimen are comulatively recorded on an accumulable phosphor sheet 1. When at first the laser beam 3 from a laser source 2 is cast onto the phosphor sheet 1 via a mirror 4, the energy on the basis of the cumulatively recorded electrons is emitted from the sheet 1 in the form of light, and this light is sensed by photo-electric booster tubes 11a, 11b. At this time, the motion positions in dynamic range of these tubes 11a, 11b are set in different positions by varying the gains of the tubes with high voltage power sources 12a, 12b. This enlarges the sensing width of the excited light based on the electrons recorded on the accumulative recording medium 1, which enables reproduction of an electron image with high accuracy.
