Abstract: A pulsation damping member includes a first metal plate and a second metal plate, a crest portion of the second metal plate enters inside a crest portion of the first metal plate, a valley portion of the first metal plate enters inside a valley portion of the second metal plate, a size in the axial direction of an outer end portion of an expansion/contraction space positioned on an outermost side in a radial direction and continuous with joint parts increases toward an inner side in the radial direction, and a first constricted portion having a smallest size in the axial direction in a portion of the expansion/contraction space positioned on an inner side with respect to the outer end portion in the radial direction is positioned on a radially outward side from a center portion between the central axis and the joint parts in the radial direction.

Abstract: A head unit to be mounted in a liquid ejecting apparatus includes: a liquid ejecting section; a first flexible substrate that transmits the electrical signal to a joining terminal of the piezoelectric element; and a second flexible substrate that transmits the electrical signal to the first flexible substrate. The second flexible substrate includes: a first region having a stack of the cover member, the conductive member, and the base member; and a second region having a stack of the conductive member and the base member. The second flexible substrate has a surface on which a terminal is disposed within the second region, the terminal being joined to the first flexible substrate with solder.

Abstract: A utility vehicle including a body, a frame, an on-board device supplied with outside air, a chamber body having an intake space and divided into a first member disposed on a first side and opened to a second side and a second member detachably attached to the first member from the second side and opened to the first side, one of the first and second members having an engaging claw, and another one having an engaging portion, and a connecting pipe connecting the chamber body and the on-board device. The first member includes a first frame-shaped outer wall, a first tip surface, and a tip protrusion protruding from the first tip surface to the second side, and the second member includes a second frame-shaped outer wall, a second tip surface, and a tip recess recessed from the second tip surface toward the second side and fittable to the tip protrusion.

Abstract: An exhaust device incorporated in a vehicle for travel on uneven terrains. The exhaust device includes an air blowing device and an exhaust pipe through which exhaust gas generated in a prime mover is directed out of the vehicle. The exhaust pipe includes an upstream pipe, a downstream pipe, and a joint device joining the upstream pipe to the downstream pipe in a manner permitting the upstream pipe to move relative to the downstream pipe, the air blowing device being disposed to blow cooling air toward the joint device.

Abstract: Provided with a pellicle inspection apparatus that inspects a pellicle film of a mask provided with a pellicle and used in EUV lithography. The pellicle inspection apparatus includes: an illumination optical system that projects a converging illuminating beam toward the pellicle film; a light collection optical system including an object lens having an optical axis substantially orthogonal to the pellicle film and that collects scattering light outgoing from a foreign substance present on the pellicle film; and a detection system that detects the scattering light collected by the light collection optical system, wherein an incident angle ?2 of the illuminating beam with respect to the pellicle film satisfies Expression ?2??0>?1+23°, where ?0 is a collecting angle (half angle) of the illuminating beam, and ?1 is a maximum light-receiving angle (half angle) of the object lens.

Abstract: Cryopreservation of primordial germ cells and germ cells, in which primordial germ cells or germ cells are separated from bird embryos before meiosis and are then suspended and frozen in a freezing medium containing a cryoprotective agent is useful for the conservation of species of birds, for the protection of rare species which are in danger of extinction and also for the production of transgenic animals, the production of novel animals having gene markers on a cellular level, the production of animals useful as disease models, the production of useful substances by genetic engineering, and the development of test methods for toxicity to germ-line cells.

Abstract: A combined structure includes a first member having at least a projection, e.g., a support, and a second member, e.g., an optical mirror, having a coefficient of thermal expansion different from that of the first member and combined cross-wise with the first member through a projection of the latter and by use of connecting members. One side wall surface of the projection of the first member and both side wall surfaces of the second member intersecting the former are bridge-connected by the connecting members at a height of a neutral plane of the second member which intersects the side wall surface of the projection of the first member. In case the first member has a plurality of projections, only those wall surfaces of the projections that face the same direction are bridge-connected to both side wall surfaces of the second member.
