摘要： A steering torque detector includes input and output shafts, a torsion bar connected between the input and the output shafts, a printed circuit board attached to the input shaft or output shaft and resistor layers and electrode as a potentiometer, having a mounting ring made of electric insulator and fitted around both the input and output shafts, and a slider attached to the mounting ring and elastically kept in contact with the resistor layers at the slider. The potentiometer includes main and auxiliary circuits each having the resistor layer and the electrode, the resistor layers of both circuits being located at a distance from each other in the radial direction of the detector and extending along mutually concentric circles through the same range of central angle of the detector. The slider includes a main slider kept in contact with the resistor layer of the main circuit at one end thereof, and an auxiliary slider kept in contact with the resistor layer of the auxiliary circuit at one end thereof. Both the main and auxiliary sliders are located at a distance from each other in the radial direction and extending along mutually concentric circles so that the one ends of both the main and auxiliary sliders are positioned on the radial direction.

摘要： A steering torque detecting apparatus for use in an electrically-operated power steering system of a vehicle. Flexural load which is applied between a pair of input and output shafts during a steering operation is absorbed by the contact between a printed board and the end of a boss portion of a mounting ring for mounting a slider, thereby preventing displacement of the position of contact of the slider with a potentiometer element. The mounting ring is provided with an elastically deformable cylindrical collar portion which surrounds the slider and the printed board is movably disposed inside the cylindrical collar portion to thereby prevent intrusion of foreign matter into the area of contact between the slider and the printed board. A bush for supporting the printed board is rigidly secured to either the input or output shaft through engagement between a positioning groove and a fixing pin and engagement of a bent end portion of the bush with a groove provided in the shaft.

摘要： An electrically powered drive apparatus comprises a first clutch plate secured to an output shaft and a second clutch plate mounted to a gear which is rotatably and slidably provided on the output shaft. The second clutch plate comprises a resilient transmission member and a magnetically-attracted contact member. The resilient transmission member is secured at a first portion to the gear and is adapted to resiliently deflect. The contact member is secured to a second portion of the resilient transmission member. The resilient transmission member has teeth into which pins extend in meshing engagement. When a clutch coil is energized, the contact member is attracted by the first clutch plate to thereby cause the pins to engage the teeth, thereby transmitting rotational force from the drive source to the gear. When the clutch coil is de-energized, the contact member is released to return to its home position with the aid of the resiliency of the resilient transmission member.

摘要： A motor-driven apparatus for controlling a throttle valve includes first and second clutch plates 11,13 mounted on an output shaft 5 opposite each other, with the second clutch plate rigidly secured to the output shaft. The first clutch plate is urged by a spring 12 toward an output gear 10 rotatably mounted on the output shaft. When the second clutch plate is magnetized, the first clutch plate is attracted to it for engagement causing the second clutch plate to rotate with the first clutch plate and the output gear, thus transmitting the torque of a motor 18 to the output shaft. An axial gap between the second clutch plate and a yoke 15 ensures rotation of the second clutch plate even when foreign substances such as iron particles are trapped in the gap because the foreign substances will easily be displaced out of the gap by centrifugal force during rotation.

摘要： A rear-wheel steering angle detecting apparatus according to the present invention includes an absolute value type rotary encoder (13) operatively connected with a rear-wheel steering mechanism for detecting the steering angle of the rear wheels of a vehicle, and a controller for finely dividing the output of the rotary encoder by the output of a pulse generator (12) for fine division of the rear-wheel steering angle. By finely dividing the rear-wheel steering angle, as detected by the rotary encoder, by the number of pulses generated by the pulse generator, which is used for speed detection, the rear-wheel steering angle is detected with a high degree of resolution.

摘要： A three way electromagnetic valve has a plunger provided with a small-diameter section, the diameter of which is smaller than the diameter of a plunger seat, so as to increase the sectional area of a fluid passage running between an output port and a discharge port. The inner wall surface of a ball holding section is provided with ball guides for guiding a ball. The diameter of the ball holding section is made larger than the diameter of the ball in order to secure the flow rate of a fluid in the ball holding section.

摘要： A strain detector to be attached to the shafts of devices such as engines, motors, electromagnetic clutches. First and second magnetic layers are disposed on the driven shaft so as to change permeability with a mechanical strain in the shaft. First and second detecting coils are wound around the first and second magnetic layers so as to be in a noncontact state therewith. Detecting means detects outputs of the detecting coils corresponding to the change in permeability. Furthermore, the driven shaft includes a heat conductive means with conductivity which is high enough to allow a temperature of each of said magnetic layers to be uniform. The outputs of the first and second detecting coils are detected in synchronism with both positive and negative drive timings of the AC drive circuit for applying an AC voltage to each of the detecting coils and smoothed and amplified thereafter, thereby allowing two strain detection outputs to be produced.

摘要： A stepping motor being a motor used in oil includes a coil formed with a conductor coated with an outer coating and wound around a bobbin, and coil terminals electrically connected to the conductor at ends thereof led out from the coil, the outer coating being removed from the conductor at the ends thereof. The coil terminals are coated with a protective film made of a material having low permeability to elemental sulfur and sulfur compounds. Therefore, coil terminals and ends of the conductor are prevented from erosion by sulfur and organic sulfur compounds, thereby reducing risk of disconnection in the coil terminals and the conductor.
