Title: Torque limiter
Inventor: KAME RYUICHIRO
IPC: F16D7/06
Filed: 1988-02-26
Abstract: PURPOSE:To transmit torque accurately to a coupling member by constructing a torque limiter such that a driven flange is arranged movably in floating state with respect to the rotary shaft of the torque limiter and the coupling face with the coupling member can take random position. CONSTITUTION:Torque is inputted from a drive source to a boss section 20a, then the torque is transmitted from the boss section 20b through a ball bearing 21 to the side of a driven flange 23 then through a holding member 22 to a coupling member 33 thence to a specific device. When overload condition occurs at the side of the driven flange 23, the ball bearing 21 springs out from a recess 23a while resisting against the resiliency of a spring 26 and moves a pressure plate 29 to the input side, and thereby the flange 23, the member 22, a spring holder 25 and the like slide to provide the function of torque limiter. When there is misalighnment between the rotary axis A of the torque limiter and the rotary axis B of the member 33, the flange 23 moves to eliminate the misalignment thus coupling them without producing a gap between the members 22, 33.

Title: Signal discriminator for automatic train operation system
Inventor: KONISHI NAOYUKI
IPC: B60L3/08
Filed: 1979-04-10
Abstract: PURPOSE: To accomplish accurate determination of malfunctioning by means of the second discrimination circuit provided in parallel with the first discrimination circuit in such a manner as to allow the second discrimination circuit to be actuated and checked with the equivalent signal to the output signal of the first discrimination circuit with the comparison of each speed signal.  
     CONSTITUTION: The second receiver 12 and the equivalent signal generation circuit 13 are changed over from one to the other by the signal change-over circuit 14 to convert the command signal received by the second receiver 12 and the signal by the demodulation circuit 15. Each signal thus converted is converted into the second and third speed signal by the conversion circuit 16. The demodulation and conversion circuits 15 and 16 compose the second discrimination circuit 17. The first and second speed signals are inputted into the abnormality discrimination circuit 18. When the two speed signals do not coincide, the change-over signal is transmitted to actuate the change-over circuit 14 to connect the equivalent signal circuit 13 and the second discrimination circuit 17. The discrimination circuit 18 outputs the abnormality detection signal when the third speed signal fails to be ascertained matching the actuating condition of the signal circuit 13. This ensures accurate discrimination of malfunctioning.

Abstract: PROBLEM TO BE SOLVED: To make a radio equipment small, which makes communication for a plurality of frequency bands. SOLUTION: A phase comparator 31 detects a phase difference between a reference frequency signal Fs and a feedback signal Fr, a phase difference signal S31 representing a phase difference is filtered by an LPF 32 to generate, a voltage signal S32. A signal S32 is given to two voltage controlled oscillators(VCOs) 33, 34.

The active VCO 33 or 34 is oscillated to generate a local frequency signal while being controlled by the signal S32. An output signal from the VCO 33 or 34 is given to a variable frequency divider 37, which frequency-divides the output signal of the VCO 33 or 34 to generate the feedback signal Fr.  That is, each of the VCOs 33, 34 is provided with a phase difference comparator 31 and an LPF 32 or the like and provides a local frequency signal suitable for each communication to the radio equipment.

Abstract: PURPOSE:To unnecessitate measures for shielding light on a heating/fixing means. CONSTITUTION:A belt conveyor is arranged on the vulcanizing side of a developing part 38, and a fixing part 44 is disposed on an intermediate part in the conveying direction of the belt conveyor. On the fixing part 44, a heater is provided on the upper part of the belt conveyor. The heater does not emit the light of wavelength with which the photosensitive layer 30 having photoconductivity, of a direct printing plate 14, is exposed, but infrared rays with which the direct printing plate 14 can be heated. Since the heater does not emit the light of the wavelength with which the direct printing plate 14 is exposed, complex light shielding measures between the fixing part 44 and the developing part 38, which is always required in the conventional plate making device, are unnecessitated.

Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To obtain at least two oscillation output signals and to suppress deterioration in C/N characteristics by deriving an oscillation output signal of a specific multiplied frequency component of fundamental oscillation signals outputted from an oscillation part including a resonance circuit part operating with a frequency control voltage and a frequency switching voltage.

Title: Excessive current protective circuit for switching regulator
Inventor: MAEDA TOMONORI
IPC: H02M3/338
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To prevent a change in an excessive current detecting point against a change in input voltage, by setting the excessive current detecting point of a switching regulator high when the input voltage is low, and setting it low when the input voltage is high. SOLUTION: The input voltage is detected by a constant voltage diode 10 and resistors 11, 12. When the input voltage is low, the constant voltage diode 10 is in an off-state and therefore a transistor 13 is in an off-state, too, and an on-state threshold value of a transistor 6 is the sum of the VBE voltage of itself and the forward voltage of the diode 14. On the other hand, when the input voltage is high, the constant voltage diode 10 is in an on state and therefore the transistor 13 is in an on state, too, and the on-state threshold value of the transistor 6 is the VBE voltage of itself. This provides the same effect as setting the excessive current detecting point lower when the input voltage is high than when the input voltage is low.

Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To improve the responsiveness of a DC torque motor by giving such angle-torque characteristics that the positive peak torque of the motor is distributed unevenly on the smaller angle side in the operating angle range of the motor, and the negative peak torque is unevenly distributed on the larger angle side in the operating angle range. SOLUTION: A DC torque motor generates a positive oscillating torque T, when a positive coil current Ic is made to flow in the operating angle range of θ=45 deg.-135 deg. and a negative oscillating torque T, when a negative coil current Ic is made to flow. For this motor having the maximum coil current of Ic=±5A, the peak of the oscillating torque T is distributed unevenly on a smaller angle θ side (for example, the peak torque is distributed in the range of θ=50 deg.-80 deg., when Ic=5A) when the positive coil current Ic is relatively large (Ic=2 to 5 A). When the negative coil current Ic is relatively large (Ic=-1 to -5A), the negative peak of the oscillating torque T is unevenly distributed on the larger angle θ side (for example, the peak torque is distributed in the range of θ=95 deg.-135 deg., when Ic=-5A).
