The object is to provide an integrated compressor that enables a control board to be miniaturized while ensuring a layout in which the heat radiation of parts is considered. Diodes 43 and IGBTs 42 that correspond to each of the U-phase, V-phase and W-phase are arrayed in series for each phase. Rectangular chips are used for the diodes 43 and IGBTs 42. As a result of this, a power board 16 is substantially miniaturized, and the diode 43, the IGBT 42, a P-terminal electrode pattern 40, an N-terminal electrode pattern 41, a shunt resistor 44, output terminal patterns 48U, 48V, 48W, and a feed pattern 50 are disposed so as to lie in a region in contact with an outer surface of a housing.

The stem slide device of the present invention in an extruder has a stem vertical movement support (71) and slide guide members (72-1, 2) fastened to the support and forming guide grooves. A stem (6) pushing against a billet loaded in a container is held at the slide table (73) horizontally. The slide table slides in the vertical direction along the vertical face of the support. When the slide table is positioned at the bottom end of the guide groove, the hydraulic cylinders (77-1, 2) are driven so that the rods (78-1, 2) push the back surface of the slide table against the vertical face of the support. Therefore, the axis of the stem is held matched with the axis of the container.

An inverter-integrated electric compressor capable of achieving improved ease of installation of a coil component constituting an inverter and increased strength and reduced cost of an insulating member, as well as a coil component for the inverter, are provided. In an inverter-integrated electric compressor, an inverter-accommodating section is disposed on the periphery of a housing, and an inverter is accommodated and installed in the inverter-accommodating section to convert DC power into three-phase AC power and supply the power to an electric motor. The inverter-integrated electric compressor includes a resin spacer member having a molded shape surrounding at least the bottom of a coil component constituting the inverter to ensure an insulation distance between the coil component and the inverter-accommodating section when installed in the inverter-accommodating section, and the coil component is fixed to and installed in the inverter-accommodating section with the resin spacer member disposed therebetween.

An object of the present invention is to provide an electric compressor for automobile use, which can satisfy a plurality of requirements including protection of an inverter board, suppression of electromagnetic noise, vibration and noise, and the like. A cover 20B covering an opening of a housing 11 of the electric compressor is configured by laminating a conductive material layer 21 formed of a conductive material and an insulating material layer 22 formed of an insulating material. By the conductive material layer 21 of the cover 20B, electromagnetic noise radiated from the inverter board 12 and the like is prevented from leaking to the outside of the housing 11. Also, by providing the insulating material layer 22 so as to be directed to the inside of the housing 11, the conductive material layer 21 of the cover 20B is insulated from the inverter board 12 to which a high voltage is applied, so that the electric compressor is made small in size. Also, by the insulating material layer 22, vibration of the conductive material layer 21 is suppressed, thus reducing vibration and noise of the electric compressor.
