Title: Constant marginal angle control system for commutatorless motor
Inventor: TAKAHASHI SATORU
IPC: H02P6/06
Filed: 1981-11-04
Abstract: PURPOSE:To perform the constant marginal angle control without accurate position detector of a commutatorless motor by always maintaining the amplitude of a magnetic flux waveform to produce a constant marginal angle pulse at the maximum rated amplitude even in a weakening magnetic flux range. CONSTITUTION:A signal f(n) responsive to the motor speed n obtained from a speed function generator 12 is determined in response to the pattern of the weakening magnetic flux. When the magnetic flux pattern is phi(n), it can be expressed as f(n)=K/phi(n), where K represents a proportional constant, is multiplied by a multiplier 11 by the speed electromotive force E obtained by a speed electromotive force arithmetic unit 5 from a motor voltage VM and a motor current IM, this multiplication signal is integrated by an integrated 6, thereby obtaining the waveform of the magnetic flux phi (the component of the effective magnetic flux in each phase). The constant marginal angle pulse having a width of an electric angle of 180 deg. outputted from a constant marginal angle pulse generator 7 which inputs the waveform phi controls the phase of an inverter through a pulse distributor 8.

Filed: 1987-07-16
Abstract: PURPOSE:To set up a simple sprinkler at low cost by forming a clamp by material having a function and a shape as a clamp at a room temperature, and at an abnormal high temperature due to fire, lossing the function of the clamp. CONSTITUTION:A water discharge port 8 is formed on the bottom of an water tank 1, and at usual time, the port 8 is clamped by a fire detecting clamp 7, a floating nut 5 and a packing 6 and water can not be discharged. The material of the fire detecting clamp 7 is solid and has strength as the clamp at the room temperature, and when the temperature is abnormally increased, losses its strength and lead alloy e.g. having 100-250 deg.C melting point may be used. Plastic having 60-150 deg.C softening point may be also used for the formation of the clamp though the material is not melted. Namely, at the time of generating fire, the fire detecting clamp 7 is deformed or ignited and burned out in case of self-combustibility. Consequently, the clamp 7 losses the function of the clamp, so that the floating nut 5 is floated and water in the tank 1 is discharged through lower holes 4, 4' and the discharge port 8.

Abstract: PURPOSE:To decrease power consumption, by cutting off a current to a Peltier element in case the input detection voltage is set between two different levels of comparison voltage. CONSTITUTION:A Peltier element 5 which performs endothermic and exothermic functions is provided between transistors TR1-3 and TR2-4 which constitute a differential amplifying circuit. A power supply +V is connected to an end of the element 5, and the differential amplifying circuit is driven by the detecting voltage VD to control an optical element, for example, to a prescribed temperature. The voltage VD is compared with comparison voltage Vr1 and Vr2 (Vr1>Vr2) through DC amplifiers 6 and 7 and then amplified to drive TR1-4 of the differential amplifying circuit. In this case, the TR2 and the TR4 of one side are driven through constant voltage diodes 8 and 9. Thus the element 5 can have three modes, i.e., both positive and negative directions (cooling and heating states) and an off-state, respectively.

Filed: 1983-09-27
Abstract: PURPOSE:To prevent an error data slot from being circulated in a network by supervising an address of the operating slot at a master transmitter of the loop network and erasing immediately a slot having an ineffective address. CONSTITUTION:A line interface devices LIU1-3 and the loop master 7 are connected in the line sharing form in a loop transmission line 8.

Abstract: PURPOSE:To monitor the drift and jitter of wavelengths at every one pulse, and to output laser beams having a fixed wavelength by holding and outputting the peak value of a light receiving signal and adjusting and controlling a wavelength adjusting means in a turnable laser oscillator on the basis of the light- receiving signal. CONSTITUTION:The peak value of a light-receiving signal E corresponding to the difference of the quantity of light reception of dye laser beams P1 from a dye laser oscillator 1 and laser beams from a Fabry-Perot-etalon 21 is held by a peak holding circuit 26. A wavelength adjusting section 28 in the dye laser oscillator 1 is controlled from the holding value. Consequently, even when one pulse width of dye laser beams P2 is shortened, wavelengths at every one pulse can be monitored, and control through which wavelengths are kept constant at every one pulse is enabled. Accordingly, stability in which the wavelengths of the dye laser beams P2 are made fixed is improved extremely, and a wavelength stabilizer is optimized for separating an isotope, etc.
