摘要： A rotary electric machine includes: a rotor; a shaft that penetrates the rotor along a rotation axis and is pivotally supported by a bearing; a stator that has a cylindrical shape, accommodates the rotor inside, and has a coil wound around an inner peripheral side; a rotor cover attached to an axial end surface of the rotor; and a casing having a flow passage for supplying oil to the bearing. The rotor cover has an oil receiving portion that forms a concentric clearance with respect to the shaft and receives the oil from the bearing in the clearance. The oil receiving portion has an injection port for injecting the oil guided to the clearance toward an inner periphery of the coil by centrifugal force.

摘要： An electrical device according to the present invention has a case (1), a metallic heat sink plate (4) disposed an opening portion (OP) of the case and a circuit board (5) arranged on the heat sink plate. The heat sink plate (4) is interposed between a capacitor (2) and the circuit board (5) so that the circuit board (5) is separated from the capacitor (2) by not only the resinous case (1) but also the metallic heat sink plate (4). Thus, electromagnetic space noise generated from the capacitor (2) is shielded or reduced by the metallic heat sink plate (4) whereby a malfunction of the circuit board (5) is prevented from occurring due to electromagnetic space noise generated from the capacitor (2).

摘要： In a cylindrical guard electrode (5) provided on the outer peripheral side of an electron generation part (31) of an emitter (3), a distal end section (5A) 5 positioned in the emission direction of an electron beam (L1) from the electron generation part (31) includes: a distal end inner-peripheral-side part (A1) having an inner-peripheral-side curved surface portion (a1) convex in the emission direction; a distal end outer-peripheral-side part (A2) having an outer-peripheral-side curved portion (a2) convex in the emission direction; and a 10 distal end middle part (A3) positioned between the distal end inner-peripheral-side (A1) and the distal end outer-peripheral-side part (A2). The distal end middle part (A3) has a flat surface portion (a3) between the inner-peripheral-surface portion (a1) and the outer-peripheral-side curved surface portion (a2) so as to extend in the direction therebetween.

摘要： Between positive and negative electrode ends of battery 50, fuse 51, main contactor 52 and electrolytic capacitor C21 are connected in series. Between positive and negative electrode ends of electrolytic capacitor C21, inverter 54 in which upper phase side EFT (54U, 54V, 54W) and lower phase side FET (54X, 54Y, 54Z) are bridge-connected is connected. Resistor R1 for precharging electrolytic capacitor C21 is connected to main contactor 52 in parallel. The resistance value of resistor R1 is set so that in a precharging period until a key switch is turned on after battery 50 is connected, when the upper phase side FET is OFF-controlled and the lower phase side EFT is ON-controlled, the charge voltage value of electrolytic capacitor C21 is set to be able to limit a gate-source voltage of the upper phase side FET to a voltage at which the upper phase side FET is not turned on.

摘要： This vehicle speed command generation device 1 generates a target vehicle speed command to be used by a vehicle speed control device. The vehicle speed command generation device 1 comprises: a shift processing unit 12 that receives an original vehicle speed command and generates each of a reference vehicle speed command in which the original vehicle speed command is delayed by a reference delay time, a first-out vehicle speed command in which the original vehicle speed command is delayed by a first-out delay time that is shorter than the reference delay time, and a delayed vehicle speed command in which the original vehicle speed command is delayed by a second delay time that is longer than the reference delay time; and a correction processing unit 16 that generates a target vehicle speed command by using the first-out vehicle speed command and the delayed vehicle speed command.

摘要： Disclosed is an ALD device in which a shower head is disposed at a position opposed to a film formation surface of a target workpiece in a chamber and has raw material gas ejection ports and OH* forming gas ejection ports alternately arranged at predetermined intervals in two film-formation-surface directions so as to face the film formation surface. The OH* forming gas ejection ports respectively include first ejection ports for ozone gas ejection and second ejection ports for unsaturated hydrocarbon gas ejection. An oxide film is formed on the film formation surface by ejecting a raw material gas from the raw material gas ejection ports and ejecting an ozone gas and an unsaturated hydrocarbon gas from the first and second ejection ports of the OH* forming gas ejection ports, respectively, while moving the target workpiece along the two film-formation-surface directions.
