A lamp unit of a vehicle headlamp characterized in a lamp unit of a vehicle headlamp includes a projecting lens arranged on an optical axis extended in a front and rear direction of a vehicle, a first light emitting element arranged on a rear side of a rear side focal point of the projecting lens, and a reflector for reflecting light from the first light emitting element to a front side to be proximate to an optical axis. A vicinity of a rear side focal face of the projecting lens is arranged with a plurality of second light emitting elements for emitting light to the projecting lens.

A substrate processing unit, by employing the processing unit to carry out different processings with different processing liquids, can make a reduction in the space for carrying out the entire process of substrate processing and a reduction in the energy necessary for substrate transportation. The substrate processing unit includes: a vertically-movable substrate holder for holding a substrate; an pan surrounding the periphery of the substrate holder; an cell, located below the substrate holder and within the pan, having in its interior a chemical processing section; and a cell cover, capable of closing the top opening of the cell, having a plurality of spray nozzles for separately spraying at least two types of processing liquids; wherein the pan and the cell each have an individual liquid discharge line.

A cooling structure of a water-cooled two-cycle parallel multicylinder engine includes: an exhaust port in a cylinder block; an air intake port disposed in a crankcase below the exhaust port; a water pump disposed in the crankcase in an opposite side of the exhaust port; a first cooling water passage introducing cooling water discharged from the water pump to a cooling water jacket of a cylinder head; and a second cooling water passage introducing a part of the cooling water discharged from the water pump to a cooling water jacket below the exhaust port, the second cooling water passage being provided in the crankcase.

The present invention provides an optical pickup corresponding to plural kinds of optical discs which can be downsized and simplified, and can compensate the spherical aberration. Optical path separation for separating the optical path of a first and a second optical beams as approaching beams to an optical disc 100 into optical paths directed to a first objective lens 51 and a second objective lens 52 corresponding to the optical beams, optical path combination for combining different optical paths of a first and a second reflected optical beams as returning beams which come in from the first and second objective lenses 51, 52, and approach-and-return optical path separation for separating the optical path of the approaching beam and the optical path of the returning beam are realized by the beam separation/composition prism 44. Furthermore, a first collimator lens 45 and a second collimator lens 47 are arranged between the corresponding first and second objective lenses 51, 52 and the beam separation/composition prism 44.

An optical adjustment device capable of correcting spherical aberration with high accuracy in a simple configuration is provided. A second lens holder fits into a guiding portion of a first lens holder, and a grip rack is placed across the second lens holder and a feed screw member and resiliently abuts against the feed screw member. The driving force of a driving source is transmitted to the grip rack via the feed screw member, and the grip rack is displaced. Therefore, it is possible to displace the second lens holder with respect to the first lens holder, and adjust the spherical aberration of an optical system.

Pairs of convex and concave rollers 10, 11 are mounted on upper and lower rotary shafts 8, 9. A positioning unit 13 is slidably attached to a slide guide 12. When a rotatable member 15 is arranged at a standing position, an annular projection 10a of the convex roller engages with a groove on one end face of the rotatable member, or an annular groove 11a of the concave roller 11 engages with a projection on the other end face of the rotatable member. The positioning unit slides while stopping at the specified positions of the roller pairs.

A paper sheet processing device includes: a charging inlet that takes in paper sheets in a conveyance direction, the paper sheets including at least one target sheet and a partition card overlapped on the target sheet, the partition card having a main surface portion having at least one identification hole group, the identification hole group having at least two through holes arranged along the conveyance direction; a detection unit that detects take-in of the paper sheets by the charging unit, and detects the identification hole group; and a control unit that determines a paper sheet is the partition card in a case where the identification hole group has been detected by the detection unit, and determines that a paper sheet is the target sheet in a case where the identification hole group has not been detected by the detection unit.

A power supply system is provided that can synchronize a primary circuit and a secondary circuit with high accuracy and are advantageous in downsizing and simplification. The system includes a first circuit including: a battery device; transistor elements to which a voltage is supplied; coil units to which a feeding current is supplied in an on state of the transistor elements; a capacitor that changes a flow direction of the feeding current; and a driving coil that turns on/off the transistor elements, and a second circuit including: coil units and a driving coil in which induced electromotive force is generated; transistor elements that are turned on/off by the induced electromotive force; and a battery device that receives supply of power in an on state of the transistor elements.
