Filed: 1983-03-15
Abstract: PURPOSE:To avoid effectively a dangerous state of the robot by giving an alarm to stop the actions of a robot in case the difference between the address of the start point or an intermediate stopping position of the robot and the data on the destination address exceeds the prescribed allowance step value. CONSTITUTION:The destination address of an arm (not shown in the diagram), etc. is set to an address A register 3 with operation of an address switch 2a.

Abstract: PURPOSE: To provide a speed controlling apparatus for induction motor used in hoisting machine, which is capable of changing the cargo lowering speed smoothly without giving shocks to the cargo at the time of lowering cargo, by making the actual cargo lowering speed to appear greater than the true value temporarily when starting cargo lowering operation.  
     CONSTITUTION: Since set speed value Ns is plus and actual speed value Ni is zero at the time of starting cargo lowering operation, desired current value is given from speed regulator ASR is minus and phase sequence changing instruction toward cargo lowering direction is given from phase sequence changing means 3. However, if auxiliary minus input capable of making the actual speed value to appear greater than the true value is given from auxiliary input generator 4 to speed regulator ASR, output Is of speed regulator ASR can be changed into plus and phase sequence changing means 3 can be thrown into its cargo raising side. Resultantly, motor IM is driven into the cargo lowering direction slowly by the weight of load while generating cargo raising torque, and its cargo lowering speed is raised to the desired value while applying the brake.

Title: Thermosensitive recording apparatus
Inventor: SATO KIYOSHI
IPC: B41J2/35
Filed: 1988-02-26
Abstract: PURPOSE:To obtain a high-quality recording image by correcting energy applied to each thermal resistor element using a correction value stored in a reference table and thereby correcting the non-uniformity of recording density due to the irregularity of a calorific value, when thermosensitive recording is performed by a thermosensitive recording head. CONSTITUTION:Image data of specified color is read from a storage device 24 by a host computer 22, and inputs image data into each first line buffer 28 by a single line of a thermosensitive recording head through an interface 26 in accordance with a command from an address controller. The image data is input to a gradation correction memory 30 to be subjected to gradation correction so that specified recording density is obtained. The image data whose gradation is corrected is input into an irregularity correction memory 32. The irregularity correction memory 32 corrects density irregularity in thermosensitive recording attributable to the irregularity of the resistance value or heat release value in a parallel direction of each thermal resistor element 8, using a correction value stored in the reference table of ROM. Thus the irregularity of the calorific value of the discrete thermal resistor 8 is eliminated, and image density is uniformized to correct the irregularity of a recording image.

In this constitution, when, with the piston 1 moved forward by means of an oil pressure P, a clutch disc 3 is pressed in the direction of connection by means of a pressure plate 2, the working force of the piston 1 is exerted on the central part O2 part of the pressure plate 2. The surface pressures of the inner and the outer surface pressures, by means of which a surface pressure on a line O2 is maximized, are averaged. This constitution enables prevention of the occurrence of deficiency in transmission torque and eccentric wear of the clutch disc.

Abstract: PURPOSE:To reduce the buzz interference by adopting the frequency characteristics at the input state of the intercarrier detection circuit as those not causing phase modulation, in the TV receiver of intercarrier system which can receive audio multiplex broadcast. CONSTITUTION:The intermediate frequency output via the tuner 1, input filter 2 and video intermediate frequency amplifying circuit 3 is fed to the audio trap circuit  4 and the correction filter 8.

Abstract: PROBLEM TO BE SOLVED: To reduce the delay of rise or fall, by providing a voltage holding means for holding the control voltage of an output control element from inversion voltage in which the output of the output control element is inversed to specific voltage. SOLUTION: When output is H output, a voltage holding means for holding the control voltage of a P channel MOS (PMOS) P3 being an output control element from inversion voltage, in which output is inversed to prescribed voltage of voltage side in which output is L outputs, is provided. For instance, in the case where the voltage of an non-inversion input terminal IN+ side is higher than that of an inversion input terminal IN-, current flows in an operation pair of NMOSN2, and since gate voltage of PMOSP3 is lowered, PMOSP3 is in a continuity state and output VOUT is an H signal. At this time, the gate voltage of PMOSP3 is held power source voltage VCC-2VGS (voltage between a gate and a source) by diodes D1, D2 being the voltage holding means. The shortness of the inversion time can be contrived.

IPC: G01R23/173
Filed: 1986-02-28
Abstract: PURPOSE:To easily identify a false spectrum by shifting a local oscillation frequency by a specific frequency according to the mode switching of the local oscillation frequency by harmonic mixing. CONSTITUTION:An input signal of frequency fRF is mixed by a harmonic mixer 3 with the N-th order higher harmonic of the output signal (oscillation frequency fLO1) of a local oscillator 1 and only an IF component is selected by a BPF, passed through a detector 6, and added as a deflecting signal for the longitudinal axis of a CRT 8. Further, the output of a sweep command signal generator 9 is applied as a deflecting signal for the lateral axis of the CRT 8 and the output of a generator 9 is inputted to the oscillator 1 through the sweep frequency control circuit 11 at the same time to sweep the oscillation frequency. When a mode change-over switch 10 is switched, its switching information is sent to a circuit 11 and shifted by 2fIF/N so that the basic equation fRF= NfLO1+ or -fIF holds for the frequency fLO1 while the sign is inverted. Namely, when the switch is switched to a plus or minus sign mode, only a false spectrum shifts on the screen, so the false signal is easily identified.
