Abstract: An electric motor control unit mounted in an automotive vehicle has a motor (3) that is variable in its rotational speed. A temperature sensing element (18s) is arranged to contact a busbar so that relays (15b) and (15c) permit switching operation in response to detection of abnormal heat generation. This controls an electrical power supply to the motor to decrease the rotational speed of the motor without complete stopping of the motor. The rotational speed of the motor returns to a normal speed from the decreased speed by switching operation of the relays (15b) and (15c) with diminishing of the abnormal heat generation.

Abstract: In a magnetic head assembly for a flexible disk drive, a write/read head and an erase head are formed with grooves defining track widths only in I-shaped cores thereof. Erase track widths are dimensioned 53 &mgr;m to 63 &mgr;m each while a track width is dimensioned 125 &mgr;m to 135 &mgr;m. These dimensions correct the extension of magnetic fluxes from gaps. Hence, the assembly does not lower the reproduction output or erase the data of adjoining tracks, thereby insuring compatibility of magnetic recording media or disks.

Abstract: A single wire steel cord is prepared by flattening a round wire to have two flat surfaces facing each other and two round surfaces interposed between the two flat surfaces to face each other, wherein a flattening ratio D/W of the wire, where D denotes the short diameter of the cross section of the flattened wire and W denotes the long diameter of the cross section of the flattened wire, falls within a range of 0.5 to 0.95. Forming is applied to the flattened wire in a direction of at least the short diameter of the cross section of the flattened wire, and the flattened single wire steel cord is embedded in a tire belt portion such that one flat surface of the cord faces that portion of the tire which is brought into contact with the ground.

Abstract: To provide an electronic piano maintaining a compact appearance and providing the key touch equivalent to that of an acoustic piano. A hammer equivalent member is composed of a butt, a L-shaped member and a catcher shank. When the butt is pushed up by a jack responsive to the key depression, the hammer equivalent member starts rotating in a direction reverse to the rotary direction of a depressed key. Subsequently, after the jack leaves the butt, the hammer equivalent member continues to be rotated inertially. By contacting the projection of the L-shaped member of the hammer equivalent member, a stopper stops the inertial movement of the hammer equivalent member. The hammer equivalent member is almost equivalent to the hammer assembly of the usual acoustic piano in inertial moment and the angle formed by the center of gravity relative to a virtual perpendicular passing a center pin. Furthermore, the hammer equivalent member is shorter than the hammer assembly in appearance.

Abstract: A wire harness consists of electrical wires, a first resin sheet and a second resin sheet. The first resin sheet includes a recess formed so as to extend along a predetermined "three-dimensional" wiring route of the electrical wires. In order to manufacture the wire harness, at first, the recess is formed in the first resin sheet. Then, the electrical wires are arranged in the recess. Next, the second resin sheet is arranged on the first resin sheet so as to cover the recess and air contained in a space defined between the first resin sheet and the second resin sheet is sucked to the outside. Finally, the first resin sheet and the second resin sheet are joined to each other. Owing to the provision of the three-dimensional recess, it is possible to realize the wire harness having a three-dimensional configuration following to the actual wiring route of the electrical wires, so that the assembling property can be improved.

Abstract: End faces of the opposite ends of an FPC for connecting a movable magnetic head and a stationary electric circuit to each other are supported parallel to the plane of a recording medium and in the substantially same plane. The height of the FPC when it is flexed and twisted can be further reduced by forming a slot or slots longitudinally in the FPC and/or by forming a repeat or repeats of an S shape on the FPC. The height of the FPC upon flexing and twisting can be further reduced by bending the opposite side portions of an intermediate portion of the FPC between the end faces longitudinally. If the vertical spacing of the FPC which is flexed by movement of the magnetic head is reduced in this manner, a device of miniaturized thickness and volume can be constructed.

Abstract: For controlling an original interruption request produced in each of peripheral units (12-1 to 12-N), the peripheral units are connected to an interruption control line (20) in common. When the original interruption request is produced, the peripheral unit in question continuously supplies an interruption control signal to the interruption control line unless the interruption control line is already supplied with the interruption control signal from other peripheral units. A timer circuit (23) of the peripheral unit in question times a preselected time interval from a time instant at which the peripheral unit in question begins to supply the interruption control signal to the interruption control line. The timer circuit suspends its operation while an interruption request line (10) is supplied with an interruption request signal from other peripheral units. When the time interval is timed, the peripheral unit in question continuously supplies the interruption request signal to the interruption request line.

Abstract: A distributing box for laying a cable duct in the construction field in is sealed, after laying the cable duct, with mortar and then buried in the ground. Accordingly, setting up the distributing box is simplified. Also, underground water must not permeate the distributing box. In the present invention, therefore, a duct laying fixture is constructed includes a box-shaped barrel of a water-expansible elastic material attached to the bellows type cable duct, and a water-expansible sheet which is stuck on the outer surface of the barrel. The barrel includes a duct mounting port in which the bellows type cable duct is mounted. Ribs are formed on the peripheral wall surface of the port to come into close contact with the outer peripheral surface of the bellows type cable duct. A slit permits spreading the barrel. The sheet is stuck on the outer surface of the barrel after the duct has been passed by spreading the barrel.

Abstract: In a satellite tracking control system, a receiver derives a pair of elevation (EL) and cross-elevation (XEL) tracking error signals having a quadratic relationship in a coordinate system from a signal received from a polar-orbital satellite. Elevation and cross-elevation motors are respectively controlled in response to the elevation (EL) and cross-elevation (XEL) tracking error signals. An azimuth controller derives an azimuth control signal from angle data representing the angles of the antenna about the azimuth, elevation and cross-elevation axes detected by angle detectors. Preferably, the antenna is rotatable about the elevation (EL) axis in the range between zero and 180 degrees.

Abstract: In a tracking system for a stationary satellite, a phased array is used for an antenna mounted on an automobile. The phased array antenna has a sharp beam which is switched between two different directions in azimuth. The antenna beam is switched between the two directions periodically by control of phase constants in a feeding circuit of the antenna and comparison is made in strength between signals received before and after the beam switching to obtain an error signal as an azimuth error signal. Then, the antenna is mechanically moved in azimuth according to the azimuth error signal until the azimuth error signal becomes zero. In a case the antenna beam is also switched between two directions in elevation, the antenna beam is switched in elevation during an interval between successive two times of the beam switching operation in azimuth and detects a difference in strength of signals received before and after the switching in elevation to thereby produce the difference as an elevation error signal.
