Disclosed is a mirror unit and a method of producing the same. In one preferred form of the present invention, the mirror unit includes (i) a mirror with a multilayered film formed on a substrate, the multilayered film having two materials periodically laminated in layers on the substrate, and (ii) a substrate deforming device for producing deformation of a shape of the substrate of the mirror, wherein, in the multilayered film, the number of laminated layers in a predetermined region of the substrate differs from that in another region of the substrate. A mirror unit producing method according to another preferred from of the present invention includes (a) forming a multilayered film on a substrate, the multilayered film having two materials periodically laminated in layers on the substrate, (b) providing substrate deforming means in association with the substrate, the deforming means having a function for producing deformation of the shape of the substrate, and (c) partially removing the multilayered film.

In a toroidal CVT includes a power roller interposed between input and output disks under a preload, a trunnion supports the power roller to permit a tilting motion of the power roller about a trunnion axis perpendicular to a power-roller rotation axis and to permit a parallel translation of the power roller relative to the trunnion in the direction of the common rotation axis of the input and output disks. The power roller includes an inner race in contact with the input and output disks, an outer race supported by the trunnion, and a power-roller bearing permitting relative rotation of the inner race to the outer race. The outer race has a low rigidity structure that promotes a deformation of the outer race so that the outer-race deformation follows the inner-race deformation, which may occur due to the preload during operation of the toroidal CVT.

Disclosed is a spectroscope and a measuring apparatus using the same. The spectroscope according to an aspect of the present invention includes a light source, a spectroscopic member for dispersing light from the light source in accordance with wavelength, a slit member arranged so that a portion of the dispersed light from the spectroscopic member can pass therethrough and a remaining portion of the light is blocked thereby, and a sensor having a spatial resolution capable of discriminating the wavelength of light passing through the slit member on the basis of a spectral distribution being projected in a spectral direction of light by the spectroscopic member. With this arrangement, the wavelength of light passing through the slit member can be discriminate real time.

A friction drive device includes a first roller with a support part, a second roller, and a cam member to support them. The second roller receives press force from the first roller at a contact point of them so as to transmit mechanical power therebetween. The cam member has a cam formed with a cam slope on which the support part of the first roller is pressed by reaction torque from the second roller that is caused by transmission torque applied from the first roller. The cam slope is formed to have an angle with respect a tangent line at the contact point so that the first roller is pressed by reaction force of the cam to apply the press force proportional to the transmission torque to the second roller.

A die pad and a plurality of leads are integrally held by a resin portion made of mold resin, and a laser chip is mounted on the die pad through a sub-mount. The resin portion (2) has a base portion (21) that integrally holds the plurality of leads, and has a substantially round shape in an external shape thereof, and a die pad holding portion (22) that is continuously formed above the base portion, and holds the rear surface and the side portions of the die pad. The die pad holding portion has an external shape that is included inside a circle P having a diameter that is smaller than the outer diameter of the substantially round shape of the base portion. Consequently, it is possible to provide an optical-disk-use semiconductor laser, such as CD-use and DVD-use semiconductor laser, which ahs the same structure as the can-type structure and an inexpensive resin package.

A high-pressure switching valve device. A valve main body pressed to contact with an end face of a valve seat when the high-pressure switching valve device is closed, and a seal member pressed to contact with the end face of the valve seat when the high-pressure switching valve device is closed. When the high-pressure switching valve device is closed, the seal member is located on a high-pressure side and the valve main body is located on a low-pressure side.
