摘要:
A thermoplastic laminate film containing a thermoplastic substrate film and a layer formed from a resin composition containing a polyester graft copolymer (A) and a resin (B), the layer being formed on at least one side of the thermoplastic substrate film, the polyester graft copolymer (A) being obtained by grafting at least one polymerizable unsaturated monomer, which contains an acid anhydride having a double bond, to a hydrophobic polyester resin, and the resin (B) containing at least one member selected from the group consisting of a polyurethane resin, an acrylic resin and a vinyl resin. The adhesion improving layer of the inventive thermoplastic laminate film shows superior adhesion strength in a broad range of applications. Specifically, it is evident in an ink layer of printing ink, UV ink and the like; an adhesive layer in dry laminate and extrusion laminating; a thin film layer obtained by vacuum vapor deposition, electron beam vapor deposition, sputtering, ionic plating, CVD and plasma polymerization of metal or inorganic substance or oxides thereof; an oxygen moisture absorbent layer; an organic barrier layer; an ink jet image receiving layer and the like.
摘要:
Power terminals of power modules are magnetically coupled to power-output terminals and power-input terminals. A heat sink has parallel surfaces, which are in parallel to the power modules and the power terminals. A magnetic field, which is generated by electric current flowing through switching devices and the power terminals, is cancelled by a magnetic field, which is generated by eddy current flowing in the heat sink.

In a band elimination filter, a plurality of capacitors are connected in parallel between first and second terminals of an electromagnetic noise source which generates voltage fluctuations in a connecting lead connected to the first terminal, with the capacitors being connected to the connecting lead at respectively corresponding branch points. For each capacitor, the total series inductance of a first circuit path is made less than that of a second circuit path, where the first circuit path extends from the corresponding branch point to the second terminal via the capacitor, and the second circuit path extends from that branch point to the first terminal of the electromagnetic noise source. A resistor is connected in series with at least one of the capacitors, for damping parallel resonance caused by inductance components of an adjacent pair of capacitors.

A control system controls a multiphase rotating machine by a 120° energization process and a PWM process. In the 120° energization process, respective ones of switching elements of a high side arm and switching elements of a low side arm of a power conversion circuit are turned on. In the PWM process, the switching elements of the power conversion circuit turn on/off so that two phases that are connected to the switching elements that are in the on-state are alternately rendered conductive to the high potential side input terminal and the low potential side input terminal of the power conversion circuit.

In a semiconductor module, a high-potential side conductor includes a wide section on which the high-potential side switching element is mounted, a high-potential side terminal coupled with a high potential source, and a narrow section extending from the wide section to the high-potential side terminal in a first direction. The wide section is wider than the narrow section in a second direction perpendicular to the first direction. The wide section has a first side and a second side opposite to the first side in the second direction. A distance between the first side of the wide section and a low-potential side conductor is shorter than a distance between the second side of the wide section and the low-potential side conductor. The narrow section extends from a portion of the wide section closer to the first side than the second side.
