摘要:
A wavelength filter includes a solid material that is optically transparent and including a pair of planar surfaces substantially parallel to each other; and a supporting member that supports the solid material on a planar surface of the solid material other than the pair of planar surfaces, the supporting member having a rigidity higher than that of the solid material. The solid material is a birefringent material of which an optical axis makes a predetermined angle with respect to a normal to the pair of planar surfaces, and the wavelength filter selects light having a wavelength that is determined by an optical length between the pair of planar surfaces by resonating the light between the pair of planar surfaces.

A backward laser beam radiated from a laser diode is received in a photo diode, and an intensity of a forward laser beam radiated from the laser diode is adjusted according to the intensity of the received backward laser beam. The forward laser beam radiated from the laser diode is collimated in a first lens held by a lens holder, and a most portion of the forward laser beam is output through a package window inclined with respect to an optical axis of the laser diode. The remaining portion of the forward laser beam is reflected on the package window as a reflected laser beam and is transmitted through the first lens to be converged in a narrow area placed above the laser diode. A light shielding plate extending in a plane orthogonal to the optical axis is arranged in a wide area including the narrow area and shields the photo diode from the reflected laser beam from. Therefore, the intensity of the forward laser beam radiated from the laser diode is correctly adjusted. Also, the light shielding plate is not soldered to the laser diode but is fixed to lens fixing posts arranged to support the lens holder. Therefore, a driving current can be supplied to the laser diode through a bonding wire without being influenced by the light shielding plate.

A seal useful in sealing slide out rooms used in recreational vehicles. The seal may be used singularly or in pairs to straddle a wall through which the opening is located. A bulb is attached to the base in a cantilevered manner over the base. The bulb has an outer arcuate portion that is integrally joined to opposing sidewall portions. The sidewall portions extend into an inner wall that defines an enclosed space within the bulb portion. The bulb portion may also have a protrusion that can touch the base. A wiper extends from the base substantially co-linearly to the base and opposite the offsetting member. A locating leg extending from the base is movable between a first position and a second position. The first position has the locating leg perpendicular to the base and the second position places the locating leg parallel to the base.

An X-ray imaging apparatus is provided with a multi X-ray source and a collimator in which a plurality of slits for X-rays to pass through are two-dimensionally formed, the size and position of the slits being adjustable. A control unit, as a first control mode, controls the size and position of the slits to move an examination region in parallel, when an X-ray source is changed to a different X-ray source, such that the examination directions are parallel before and after the change. Also, the control unit, as a second control mode, controls the size and position of the slits to rotate the examination direction, when an X-ray source is changed to a different X-ray source, such that the center of the examination regions is the same before and after the change.

A communications system and method, an information processing apparatus and method, an information management apparatus and method, a recording medium and a program make it possible to efficiently and comfortably make use of contents, which are stored in one server, from a plurality of devices connected via a network. In a case in which the playing of content is stopped, bookmark information including a time stamp representing the stopped position of the content is stored in association with predetermined identification information. The bookmark information is available for various apparatuses transmitting the identification information. When playing the content from a position designated by the information from a predetermined apparatus, the time stamp included in the bookmark information is referred to and the playing of the content from the stopped position is started. The present invention can be applied to various apparatuses such as a personal computer, audio equipment, a PDA, a mobile phone and the like.
