摘要： PURPOSE:To ensure the smooth travelling of a magnetic tape regardless of the presence of a dropout, by feeding an output pulse given from an oscillator to a speed control circuit in the form of a pseudo pulse when no speed detecting pulse is obtained from the tape. CONSTITUTION:In the normal travelling mode of a magnetic tape 3, the output pulse given from a recording circuit 1 is recorded on a magnetic tape 3 through a recording head 2. The recorded speed detecting pulse is reproduced by a reproducing head 4 and fed again to the circuit 1 through a reproducing circuit 5 and an OR circuit 6 to be also supplied to a speed control circuit 7. As a result, a motor is controlled to make the tape 3 travel at a certain speed. The pulse signal is not delivered any more from the circuit 5 and at an area where a dropout exists on the tape 3. This fact is detected by a detecting circuit 8, and an oscillating circuit 9 is actuated. The output of the circuit 9 is supplied to the circuits 1 and 7 in the form of a pseudo pulse.

摘要： PURPOSE:To enable operation at the maximum thermal efficiency as to the temperatures of heat sources, by detecting the difference between the inlet temperature and inlet saturation temperature of an expander and controlling the circulation flow rate of a working fluid to keep the temperature difference constant. CONSTITUTION:The inlet temperature of an expander 1 is detected by a temperature sensor 12. The inlet pressure of a steam generator 3 is detected by a pressure sensor 8 and changed into the saturation pressure of a working fluid. The difference between the saturation pressure of the working fluid and the inlet pressure of the steam generator 3 is utilized to regulate the degree of opening of a throttle valve 6 by a valve controller 13 to keep the degree of inlet superheating of the expander 1 constant. As a result, the circulation flow rate of the working fluid is controlled to be appropriate with regard to the temperatures of heat sources to operate a Rankine-cycle-type motive power generator at the maximum thermal efficiency.

摘要： PURPOSE:To simplify the forming work as well as to improve the accuracy in the finished form of the subject armature coil by a method wherein a printed coil and a heat sensitive adhesive film are superposed, wound into a cylindrical shape and are adhered under heat and pressure. CONSTITUTION:The printed coil 1, which has been formed by a printed wiring using a plurality of unit coils, and the heat sensitive adhesive film 13 are superposed and wound into a cylindrical shape. Then, the above is heated and pressurized, the adhesive agent is fused once and then hardened and a unit armature coil 20 is formed into one unitary body. Through these procedures, the coil forming work can be simplified comparing with the case wherein a liquefied adhesive agent is used and also there exists no variation in the finished form of the armature coil.

摘要： PURPOSE:To enable torque ripple under rotation of a rotator such as electric motor to be measured by connecting a mounting table which rotates in one piece with the motor to a load sensor which is fixed at one end to a fixing table. CONSTITUTION:A mounting table 12 which is rotatable around a shaft 11 is mounted by way of the bearing 13 of a fixing table 10, and an electric motor 1 having an output shaft 3 is so installed that it rotates in one piece with said mounting table 12. Since a load sensor 14 is connected at one end to the table 12, and is fixed at the other end to the table 10, the force generated in the stator and rotor parts during the running of the motor to be measured outputs torque and revolution in the output shaft 3, which simultanously generates the reaction of the shaft output in the stator part, and this reaction is applied as a position displacing force to the fixed load sensor 14; therefore, if the output of the load detecting element of this load sensor is measured, the torque ripple of the motor 1 is measured.

摘要： PURPOSE:To detect stably the speed of a rotary material which is changed by a wide-range frequency, by utilizing an output independent of the frequency of the fundamental wave of a speed generator. CONSTITUTION:First speed generator 11 which has amplitude B changed according to the rotation speed of rotary material 10 and has an output of Bsintheta and second speed generator 12 which has amplitude A changed according to the rotation speed of rotary material 10 and has an output of Acos2theta are provided. The output of first speed generator 11 is inputted to regulator 17 and is adjusted to have amplitude B=2A and is further squared by square circuit 18, and next, both outputs are inputted to adder circuit 19. Output V of adder circuit 19 is a value shown in expression I, and DC signals proportional to the rotation speed of the rotary material can be obtained. Thus, since the output independent of the frequency of the fundamental wave of the speed generator can be obtained, the speed of the rotary material which is changed by a wide-range frequency can be detected stably.
