    摘要： An image formation device includes a receiving section, a formation section, a fixing section, a switching section, and a controller. The receiving section receives image formation data including image data, and sheet data which includes designations of a sheet and a corresponding fixing pressure. The formation section forms a toner image on the sheet. The fixing section fixes the toner image on the sheet. The switching section switches the fixing pressure between a first or second fixing pressure. When the fixing pressure is switched to the second fixing pressure and the fixing pressure designated by the sheet data is the first fixing pressure, the controller performs a mandatory image formation that includes a low-speed control that conveys the sheet at a speed lower than that for the first fixing pressure, and/or a toner suppression control that performs image formation with a smaller amount of toner than in normal.

    摘要： In an optical waveguide device of the present invention, optical element mount (17) includes first base block (19a) for supporting first optical element (18a) and second base block (19b) for supporting second optical element (18b) that has an active layer depth smaller than that of first optical element (18a). Second base block (19b) is formed from stacks of upper clad layers whose number of stacks is larger than that of first base block (19a). Difference (h1) in height between the first and second base blocks is equal to difference (d1−d2) in active layer depth between the first and second optical elements.

    摘要： An optical waveguide device includes: a substrate; an optical element arranged on the substrate; and an optical circuit part having an optical waveguide formed on the substrate. The optical circuit part includes: a core whose optical axis is matched with the optical element; and a dummy core arranged on a same layer to the core and exposed on a side being not opposed to the optical element when the optical element is arranged on the substrate. The relative position between the optical waveguide and the optical element can be recognized by observing the dummy core. The planar shape of the optical circuit has a convex portion. The width of the convex portion and the width of the optical element are same in the opposing edge face where the optical element and the core is opposed to one another.

    摘要： According to the present invention, there is provided a method for preparing an optically active compound, characterized in that said method comprises permitting a mixture of optical isomers relative to the carbon atom in the β-position in relation to the carbon atom bound to an esterified hydroxy group of an enol ester to hydrolyse either one optical isomer preferentially in the presence of an enzyme and allowing the carbonyl compound resulting from such hydrolysis to enrich the proportion of its isomer having either one configuration in the β-position in relation to the carbonyl group or allowing the enol ester left non-hydrolyzed to enrich the proportion of its isomer having either one configuration on the carbon atom in the β-position in relation to the carbon atom to which the esterified hydroxyl group bonds.

    摘要： An optical waveguide device which includes an optical waveguide part and a photonic device mounting part is provided. A mask to form a pedestal block on which a light emitting device is mounted is patterned after high-temperature annealing. Thus, there is no influence on the mask, even if the device undergoes the heat treatment at a high temperature during the manufacturing process. This enables formation of the pedestal block with high accuracy. Therefore, it is possible to achieve an optical coupling with high accuracy in mounting a light emitting device on the pedestal block.
