Abstract: Provided is a heater including: a substrate that has electrical conductivity; a first insulation portion that is provided on a first surface of the substrate, has an insulation property; at least one heat generation body that is provided on the first insulation portion; a second insulation portion that is provided on a second surface of the substrate which is opposite to the first surface, has an insulation property; at least one detection unit that is provided on at least one of the first insulation portion and the second insulation portion; and a first wiring which is provided on at least one of the first insulation portion and the second insulation portion, and in which one end is electrically connected to one terminal of the detection unit and the other end is electrically connected to the substrate having the electrical conductivity.

Abstract: Electric power steering system comprises an electric motor (9) for producing a steering assist force reducing a steering effort of a vehicle operator and a control unit (21) determining a control value for the electric motor, the control unit being configured to determine the control value by selecting a map representing a relationship between a vehicle state variable and a control value for each of a plurality of control modes. When switching control modes, the control unit gradually changes the control value from that obtained from a map corresponding to a preceding control mode to that of a following control mode. A different time period of gradual transition from the preceding control mode to the following control mode is selected depending on those control modes.

Abstract: An eddy current flaw detection apparatus, having: a pair of detecting coils disposed in a separated manner along a transit path of a conductor and coaxial with the conductor, magnetic fields generated by said detecting coils being in anti-phase; an alternating current bridge circuit, two sides of a bridge of which are comprising the detecting coils, and which, when a relative change occurs in inductances of the detecting coils and equilibrium of the bridge is thus disturbed, outputs an abnormality detection signal; a pair of resonance coils, which are disposed between the detecting coils, and coaxial with the detecting coils, and magnetic fields of which are in phase, and which are so set that in a state in which the bridge is in equilibrium, induction currents generated by said resonance coils cancel each other out; and a capacity circuit for the purpose of bringing oscillation frequencies of the detecting coils into resonance, which is connected to the resonance coils.

Abstract: An adhesive tape is provided which comprises a film of high density polyethylene having a density of not less than 0.94g/cc elongated at least six times only transversely to the longitudinal direction of the tape and a layer of pressure sensitive adhesive applied at least on one side of said elongated film of high density polyethylene. The adhesive tape has a high tensile strength against a force applied in a direction transverse to the longitudinal direction of the tape. Nevertheless, the tape can be easily torn or cut by user's hand or hands exactly transversely to the longitudinal direction of the tape without being torn zigzag or in a slanting direction.

Abstract: An adhesive tape is provided which comprises a base paper material having a thickness of 30 to 150 g/m.sup.2, a film of high density polyethylene having a density of not less than 0.94 g/cc elongated at least six times only transversely to the longitudinal direction of the tape and having a thickness of 15 to 30.mu., said elongated film being attached to one side of said base paper material with a first layer of low density polyethylene of a thickness of 7 to 50.mu. being extruded between the base paper material and the elongated film, a second layer of low density polyethylene of a thickness of 7 to 50.mu. being extruded and attached to said elongated film so that the elongated film is sandwiched between the first and second layers of low density polyethylene, and a layer of pressure sensitive adhesive applied to the other side of said base paper material. The adhesive tape has a high tensile strength against a force applied in a direction transverse to the longitudinal direction of the tape.
