摘要： A starter for an internal combustion engine comprises a starter motor. A drive shaft extends in coaxial relation to an armature shaft of the starter motor and has a projection extending radially outwardly from an axial end of the drive shaft adjacent the armature shaft. A pinion is in spline engagement with an outer periphery of the drive shaft and in meshing engagement with a ring gear of the engine. The rotation of the armature shaft is reduced in speed and transmitted to the drive shaft through a planetary gear type speed reducing mechanism. A center bracket comprises a cylindrical portion rotatably supported by one of the drive shaft and the armature shaft, and a disc-shaped portion extending radially outwardly from an axial end of the cylindrical portion. A shock absorber unit comprises a rotary disc and a spring disposed around the cylindrical portion of the center bracket. The rotary disc engages an internal gear of the planetary gear type speed reducing mechanism so as not to be rotatable, but to be axially movable with respect to the internal gear. The spring urges the rotary disc against the disc-shaped portion of the center bracket. The rotary disc and spring are retained by a retainer in their respective positions around the cylindrical portion of the center bracket.

摘要： An angular position sensor is provided which is designed to an angular position of a rotary shaft. The angular position sensor has a magnet affixed to the rotary shaft. The magnet has an N-pole and an S-pole and is so geometrically shaped as to produce magnetic flux which is substantially uniform in amount within a range extending around each of centers of the N-pole and the S-pole. This improves the linearity of a change in sensor output upon rotation of the rotary shaft.

摘要： A composite cable with built-in signal an power cables is mainly used as a control cable for a machine tool and the like. The composite cable contributes to reduced cost, downsizing, higher reliability and higher safety, which are obtained because only a single cable needs to be laid, instead of the conventional cable, which requires multiple cables to be laid. In the composite cable with the built-in signal and power cables, a flat signal cable formed by a plurality of insulating cores arranged in parallel in the lengthwise direction, and having alternately repeated combined portions and separate portions is spirally wound into a roll around one or more power cables provided in the center of the composite cable. The power cables each have a large conductor size. A first shield is optionally provided around the flat signal cable. A second shield is optionally provided around the power cables. A sheath is provided around the flat signal cable or the first shield.

摘要： A low-noise electric structure of an electric power steering device for automotive vehicles is provided which includes a controller including a substrate on which drive devices working to drive an electric motor are installed. The drive devices, power supply terminal joints, and motor terminal joints are concentrated on a portion of the substrate, thereby permitting a path of current flowing from the power supply terminal joints to the motor terminal joints to be shortened. This results in a decrease in quantity of heat generated from a circuit line extending between the power supply terminal joints and the motor terminal joints.

摘要： In a pedal force detection device, a pedal arm unit is provided with a first arm at which a pedal is mounted, a second arm apart from the pedal and a connection portion for connecting the first and second arms. A load sensor having a matrix made of a ceramics is fixed between the first and second arms. When the pedal is depressed by a pedal force, the first arm approaches the second arm due to a resilient deformation so that the load sensor is compressed by a load. Thus, the pedal force can be determined based on the load detected by the load sensor.

摘要： In a load detecting device, a hermetically sealed sensor chamber is constituted by a sensor head, a bellows, a housing and a stem. A sensor chip for detecting pressure is housed in the sensor chamber that is filled up with liquid. When load is applied to the sensor head, the bellows contracts axially to vary pressure of the liquid. The sensor chip senses the pressure of the liquid so that the load applied to the sensor chamber is detected with higher detecting accuracy.
