Filed: 1985-01-11
Abstract: PURPOSE:To prevent the repeat of oscillation near a target value by generating no outputs in a position feedback system within the rang of + or -1 bit with the target value as the center. CONSTITUTION:A motor 1 driven by a servo controller is connected to a load like the joint of a robot through a decelerator. The position of the motor 1 is detected by a potentiometer 2, and the speed of the motor 1 is detected by a tachogenerator 3. These outputs are inputted to a control microcomputer 6 through a multiplier 4, an adder 8, and an A/D converter 5. this microcomputer 6 calculates the difference between a target position X0 and a present position X and multiplies this difference by a multiplier K, and the motor 1 is driven through a D/A converter 7, the adder 8, and a control IC9 in accordance with this multiplication output. If the difference between the target position X0 and the present position X is + or -1 bit with respect to a position variable, the microcomputer 6 sets the position feedback to zero. Thus, a robot arm is stopped in the target position without damaging the response speed of a control system.

Title: Ultrasonic wave oscillator driving device
Inventor: HASHIGUCHI MUTSUO
IPC: H04R1/00
Filed: 1980-01-18
Abstract: PURPOSE:To increase signal-to-noise ratio (S/N) and miniaturize an ultrasonic wave oscillator driving device by generating driving pulses of energized signal generator so as to short-circuit unnecessary pulses caused by miss-matching around the ultrasonic wave oscillator with the output terminal of energized signal generator. CONSTITUTION:A rate pulse generated in rate pulse generator 1 passes through OR gate 2, inverter 3 and driving inverter 4 and, when FFT5 is turned on, the charge charged in condenser C starts to flow into inductance L as current by resistance R1. When FET5 is turned off after a prescribed time, inductance L generates reverse electromotive force to drive ultrasonic oscillator 6 and then ends the operation after generating a energized signal. The rate pulse outputted from generator 1 is also inputted into delay pulse generator 7 consisting of monostable multioibrator MM1 and MM2 and, when FET5 is turned on again with the timing delayed by generator 7, the output terminal is terminated. Since the period is optionally set up by the unnecessary waves generated by miss-matching of oscillator 6, unnecessary pulses can be removed without attenuation of energized pulses.

Title: Picture compensating device
Inventor: KUBO SUMIKAZU
IPC: H04N3/16
Filed: 1981-01-14
Abstract: PURPOSE:To compensate the raster distortion caused by the fluctuation of a CRT current, by detecting a part of the high pressure to be applied to a CRT and then amplifying the high voltage to feed it back to a part of a deflecting distortion compensating circuit. CONSTITUTION:The detection is carried out to a part of the CRT voltage which is caused by the fluctuation of the CRT current at point A in the figure and modulated by a vertical rate. This detected voltage is controlled by a variable resistance VR2, amplified by a transistor TRTR2 and furthermore receives the amplification and the inversion of phase through a TRTR3. The output is applied to point B of a vertical line compensating output circuit via a DC breaking capacitor C3 and an impedance resistance R5. Then the signal amplified by a TRTR1 is supplied to a winding L2 of a vertical line compensating transformer T1. Thus the maximum point of the raster amplitude is identical with the minimum value of the current flowing to the winding L2, and the inductance increases for windings L1 and L3 to decrease the horizontal deflecting current. As a result, the raster distortion caused by the current fluctuation of the CRT can be compensated.

Abstract: PURPOSE: To reduce the isolating area of isolating region for insulating and isolating a reverse conductivity type epitaxial layer grown on one conductivity type semiconductor substrate by forming a deep one conductivity region in the epiaxial layer between two shallow oxide layers formed in parallel in the isolating region when insulating and isolating the epitaxial layer.  
     CONSTITUTION: When an n-type layer 2 is epitaxially grown on a p-type silicon substrate 1 and isolated in an island state using an insulating region, an SiO 2  film 9 and an Si 3 N 4  film 11 are first laminated on the layer 2. Then, two openings 12 and 13 are perforated at an interval on the region to be formed with an isolating region, and heat treated, thereby forming shallow oxide layers 14 and 15 in the layer 2 exposed through the openings 12 and 13. Thereafter, the films 11 and 9 of the region surrounded by the layers 14 and 15 are removed, and a p + -type insulating region 17 is diffused in the portion 16 of the exposed layer 2, thereby isolating the layer 2 in an island state. Thus, the area required for insulating and isolating the layer 2 can be reduced, thereby obtaining an IC having high integrating degree.

Title: Display plate
Inventor: TAMURA SEIZO
IPC: G09F7/00
Filed: 1994-01-21
Abstract: PURPOSE:To prevent an adhesive sheet from being peeled at a join part by a strong wind by providing a cavity part which is open to the outside at both ends crossing the top-reverse direction at right angles between the top and reverse sides of the join part. CONSTITUTION:When the string wind strikes on the reverse surface of the display plate and enters the cavity part A through the joint part between both constituent plates 14 and 15, the air pressure in the cavity part A increases. The left and right ends A' of the cavity part A are open to the outside, so the air entering the cavity part A exits from the opening ends A'. Consequently, the air pressure in the cavity A does not become high so much. Therefore, an air leak to a gap B which is open to the top surface at the join part between both the constituent plates 14 and 15 is reduced. The wind pressure operating on the reverse surface of the adhesive sheet 34 through the gap B becomes extremely small and the adhesive sheet 34 is not peeled off with this wind pressure.

Abstract: PURPOSE:To make the leading edge and trailing edge of an output signal waveform nearly the same in period by inverting two signals by two inverters respectively, applying wired OR to AND of two signals and AND of inverted two signals, and inverting the result. CONSTITUTION:A signal A is supplied to an inverter 22 comprising a P-channel MOS transistor(TR) P10 and an N-channel MOS TR N10 and fed to a transmission gate 25.

Output terminals 24, 25 are connected in common and the connecting point is connected to the input terminal of an inverter 26 comprising a P-channel MOS TR P14 and an N-channel MOS TR N14. When only the signal B goes to an L level among signals A, B both are at H level, the charge flows to a terminal 27 through the P-channel MOS TR P14 only from the power supply VDD, and the delay of the leading edge of the signal is nearly the same in period as that of the trailing edge because the resistance is small.
