Abstract: PURPOSE:To realize miniaturization through circuit integration by implementing quadruple phase modulation through digital signal processing. CONSTITUTION:Roll-off filtering is applied to an usual input base band signal by digital filters 1,2, and one data are selected by a 1st data selector 3 receiving a sample clock based on the results of two calculations. A 2nd data selector 6 receiving the output of the 1st data selector 3, the inverted output of the 1st data selector 3 by a bit inverter 4 and a sample clock subject to 1/2 frequency division by a frequency divider 5 selects the other data. Thus, a QPSK modulation wave is obtained as a digital signal, it is converted into an analog signal by a D/A converter 7 and a low pass filter 8 is used to cut off harmonic frequency components to obtain an analog modulation wave.

Title: Robot control system
Inventor: NISHIDA AZUSA
IPC: G05B19/42
Filed: 1985-06-26
Abstract: PURPOSE:To drive respective axes of a robot smoothly and to improve tact time by automatically correcting a teaching point near a teaching point specified as no positioning. CONSTITUTION:A rectilinear distance LDST between a reference point and an objective point is found out at first, and then an accumulated interpolation distance SVL from a teaching point is reset to calculate an interpolation distance VELN for the current stage. The found interpolation distance VELN is added to an accumulated interpolation distance SVL to obtain a new accumulated moving distance SVL. If the accumulated moving distance SVL is larger than a distance between teaching points, the interpolation processing is completed in case of no positioning. If smaller, respective elements of the interpolation position are calculated to move the robot to the interpolation position point. Then, the succeeding interpolation distance is found out. Thus, a route can be omitted near the teaching point specified as no positioning, so that the tact time can be shortened and the robot can be smoothly driven.

Title: Voltage-controlled oscillator
Inventor: AABINGU JII POSUTO
IPC: H03L7/099
Filed: 1994-05-30
Abstract: PURPOSE: To eliminate the need for a varactor diode from a voltage-controlled oscillator by varying the effective variation amount of capacitance in a resonance circuit so that the resonance frequency of the resonance circuit may be varied nearly linearly by means of the control voltage of the oscillator. CONSTITUTION: In response to random noise, a transistor 4 supplies an output voltage to the load resistor R6 of its collector circuit and a driving voltage to the base of a transistor Q2. When transistors Q3 and Q4 are conducted, the AC emitter current of the transistor Q2 is separated between the emitter- collector paths of the transistors Q3 and Q4 after passing through a serial resonance circuit of an inductance L0 and a capacitor C0. When both the transistors Q3 and Q4 are turned on, in addition, the ratio between the collector currents of leads IIN1 and IIN2 decides the capacitance capacity of a capacitor CX and the amount of capacitive reactance and oscillation frequency of the serial resonance circuit are decided. Therefore, the current of the transistor Q3 is varied more linearly by the control voltage.

IPC: G01M3/24
Filed: 1999-05-19
Abstract: PROBLEM TO BE SOLVED: To precisely detect the presence of an abnormal position of a conduit and specify its position by successively performing a preprocessing sufficiently considering both characteristics of leak sound and noise of the abnormal position, a correlation processing, and further a post processing. SOLUTION: The receipt signals of ultrasonic sensors 3a, 3b, and 3c are read in a receiving part 71 according to the instruction of a control part 7 to calculate a power spectrum by use of a plurality of specified expressions. The combination of two ultrasonic sensors, for example, 3a and 3b is selected, and the cross spectrum of the receipt signals received by the sensors 3a, 3b is calculated by a specified expression. The coherence is also calculated by a specified expression. The characteristic of a SCOT filter is determined to filter the cross spectrum by a filter having frequency characteristics of a specified expression. The filtered cross spectrum is transmitted to a correlation processing part 72b to calculate the mutual correlation function, and the envelope detection is performed in a post processing part 72c.  When the frequency of envelope memory storage is equal to a predetermined repeat frequency of data read, the repeat is ended, the envelopes are averaged to determine the delay time to the receiving time of the ultrasonic sensor. One or both of peak values of the mutual correlation functions averaged between the sensors 3a and 3b and between 3a and 3c is compared with a predetermined threshold to judge the presence of an abnormal position 2, and its position is specified.

Abstract: PURPOSE:To prevent the breakage of a rotary valve and a pad due to the biting- in for powdery material by installing a cylindrical part in concentric form at the both edge parts in the center direction of the rotary valve and covering the rotary valve by a cylindrical ring pad whose revolution for a casing is suppressed. CONSTITUTION:When a rotor 30 (rotary valve) is revolved in the X1 direction by a rotary shaft 31, the rotor 30 revolves with the cylindrical part 51 of a disc- shaped end plate 50 installed onto the both edges of a blade 32 extending in the direction of the center line, in a ring pad 23 whose revolution for a casing 1 is suppressed. When powder material is supplied from a feeding port 10, said powder material passes through a cylindrical member 12 and is charged by a certain amount successively into the pocket of the rotor 30. The powder material is discharged through a discharge port by the gravity when the pocket is opened downwardly from an exit 66. When the powdery material clogs the part between the rotor 30 and the ring pad 23, said pad 23 is set eccentric and the interval is spread, and therefore, the strain of the blade 32 and the destruction of the pad 23 due to the biting-in for powder material can be prevented.
