Systems and methods are provided in which an extreme ultraviolet (EUV) light generation apparatus used with a laser apparatus is configured to detect an image of a laser beam by which a target has been irradiated. The EUV light generation apparatus may also be configured to control the position at which a laser beam is to be focused and the position of a target, based on the detection result.

An extreme ultraviolet light source apparatus, in which a target material is irradiated with a laser beam from a laser apparatus and the target material is turned into plasma, thereby emitting extreme ultraviolet light, may include a burst control unit configured to control irradiation of the target material is irradiated with the laser beam outputted successively in pulses from the laser apparatus when the extreme ultraviolet light is emitted successively in pulses. The target material is prevented from being turned into plasma by the laser beam while the laser beam is outputted successively in pulses from the laser apparatus when the successive pulsed emission is paused.

An alternator according to the present invention includes: a shaft; a rotor that is fixed to the shaft; a stator that has a stator core that is disposed so as to surround an outer circumference of the rotor and in which a plurality of slots that extend axially are formed so as to be spaced apart circumferentially; and a front bracket and a rear bracket that hold circumferential edge portions of the stator core from two axial ends using a plurality of holding means and that envelope the stator core, a pair of first stays that are formed on the front bracket being fixed to a vehicle by bolts that penetrate through a pair of penetrating apertures that are respectively formed on the first stays, and the pair of penetrating apertures are formed at positions such that an approximate perpendicular bisector of a straight line that connects centers of the penetrating apertures intersects an axis of the shaft; and one of the holding means is disposed on the perpendicular bisector near the shaft. This configuration can prevent generation of magnetic noise without increasing weight in the brackets, in other words, without increasing overall weight.

An AC generator comprises a shaft, a rotor secured to the shaft, a stator with a stator core provided to surround the outer circumference of the rotor and having a plurality of slots formed to extend in the axial direction while spaced apart in the circumferential direction, and a front bracket and a rear bracket surrounding the stator core while clamping the circumferential edge portion of the stator core from the opposite sides in the axial direction using a plurality of clamping means. A pair of front stays formed in the front bracket are secured to a vehicle by means of bolts penetrating a pair of through holes formed, respectively, in the pair of front stays. The pair of through holes are formed at such positions as the perpendicular bisector of a line connecting the centers intersects the axis of the shaft, and one clamping means is provided on the shaft side perpendicular bisector. With such an arrangement, generation of magnetic noise can be prevented without increasing the weight of the bracket and thereby the overall weight.

A yarn feeder for a tufting machine is compact and simple in structure and is still capable of freely changing the heights of piles formed by each pile yarn on a fabric. The yarn feeder includes yarn feed rolls for feeding pile yarns to a row of needles of the tufting machine, and a brake device provided between the feed rolls and the needles. The brake device includes a grooved plate having grooves arranged in the width direction of the grooved plate and each receiving one of the pile yarns that are being fed from the feed rolls to the needles, and presser members each opposing one of the grooves. The presser members are movable toward and away from the respective grooves independently of one another. By pressing selected one or ones of the presser members against the bottoms of the corresponding grooves with yarns sandwiched therebetween, the feed rates of the yarns can be freely changed independently of one another without unduly increasing the size of the yarn feeder or complicating its structure.

A cabin light unit for an automotive vehicle includes a vanity mirror section arranged at a location adjoining a cabin light source. The vanity mirror section is pivotably supported on a supporting plate via a stay so as to be movable between a housed position in which the vanity mirror faces the supporting plate, and an operating position in which the vanity mirror section projects from the supporting plate. The stay has a plurality of pivotal axes so that any desired positioning and directional orientation of the vanity mirror can be achieved.
