    • 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.

    • 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.

    • In light that is irradiated from a front light of a vehicle illumination device, a portion thereof is modulated to include a light signal, and a camera captures light from the front of the vehicle. The vehicle illumination device identifies luminance point(s) in the captured images of the camera, and also detects for the light signal, and extracts the luminance point(s) in the captured images other than the luminance point(s) with the detected light signal. The vehicle illumination device identifies segmented region(s) in the light distribution range of the front light that correspond to the extracted luminance point(s), and control is undertaken of the light distribution such that the identified segmented regions are made in a non-illuminating state, and the segmented regions other than those identified are illuminated. By doing so, control of the light distribution for light that is irradiated from the vehicle itself may be prevented.
    • 在从车辆照明装置的前灯照射的光中,其一部分被调制为包括光信号,并且相机从车辆的前方拍摄光。 车辆照明装置识别摄像机的拍摄图像中的亮度点,并且还检测光信号,并且利用检测到的光提取除了亮度点之外的捕获图像中的亮度点 信号。 车辆用照明装置识别与所提取的亮点对应的前灯的配光范围内的分割区域,并且进行光分布的控制,使得所识别的分割区域成为非限制性区域, 照明状态,并且被识别的分割区域被照亮。 通过这样做,可以防止对从车辆本身照射的光的配光的控制。
