A variable shape mirror includes a support substrate, a mirror substrate that is opposed to the support substrate, a fixing member that is disposed on the support substrate and fixes the mirror substrate, and a piezoelectric element that is disposed on the support substrate and is expanded or contracted so that a reflection plane of the mirror substrate can be deformed. A coefficient of linear expansion of the fixing member is larger than a coefficient of linear expansion of the piezoelectric element. A back surface of the mirror substrate is provided with a metal bonding layer that is disposed in at least a portion to be bonded to the fixing member. The metal bonding layer enables the mirror substrate and the fixing member to be bonded to each other by pressing the mirror substrate and the fixing member to each other while they are heated. The mirror substrate and the piezoelectric element are not bonded to each other.

An image processing apparatus includes an input section and a binarizing section. The input section inputs multilevel image data. The binarizing section binarizes multilevel image data to generate output image data representing halftone dots each having a hollow-structure. The binarizing section enlarges the halftone dots in a predetermined direction preferentially in accordance with the input multilevel image data.

A friction roller (10) includes a support roller (11) and an annular elastic ring (15) which it externally fitted to the support roller (11). The support roller (11) is divided into two portions in a thickness direction, that is, a first divided roller (12) and a second divided roller (13). A flange (127) is formed on one side of the first divided roller (12), and a taper face (128) is formed in an outer peripheral face of the first divided roller (12). A knurling portion (129) is formed in the taper face (128). A flange (136) is formed on one side of the second divided roller (13), and a taper face (137) is formed in an outer peripheral face of the second divided roller (13). A knurling portion (138) is formed in the taper face (137). Meanwhile, taper faces (151, 152) expanding outward are formed in an inner peripheral face of the elastic ring (15). The taper faces (151, 152) of the elastic ring (15) are engaged with the taper face (128) of the first divided roller (12) and the taper face (137) of the second divided roller (13).

摘要:
An optical pickup device has a variable-shape mirror that reflects a light beam emitted from a light source and that, by use of piezoelectric elements sandwiched between a support substrate and a mirror portion arranged to face the support substrate, corrects for wavefront aberrations in the light beam by deforming a mirror surface of the mirror portion, and converging means for directing, while condensing, the light beam reflected from the variable-shape mirror to a recording surface of an optical recording medium. Let a direction perpendicular to the travel direction of the light beam emitted from the light source be the X direction on the mirror surface and let the direction perpendicular to the X direction be the Y direction on the mirror surface, the mirror surface is inclined about the X direction such that the mirror surface forms a predetermined angle relative to the travel direction of the light bean emitted from the light source. The piezoelectric elements are arranged symmetrically about the center axis of the mirror surface, with two of them arranged in the X direction and another two in the Y direction. The piezoelectric elements are arranged on the support substrate such that, when all of them are driven with equal voltages, the curvature of the mirror surface in the X direction relative to the curvature of the mirror surface in the Y direction fulfills a predetermined curvature ratio.

(S)-(−)-5-hydroxy-1-methylhydantoin is useful as a drug having high safety. Since the compound of the present invention, (S)-(−)-5-hydroxy-1-methylhydantoin, rarely changes to the metabolite having high toxicity compared with the R-form and the racemate, it is preferred as an agent for renal failure especially when used for chronic renal insufficiency in a patient where toxic substances are not excreted, but are accumulated in the body due to disturbance of renal functions.
