A steering wheel includes a functional device and a control device, which is electrically connected to the functional device. The functional device includes a functional case, which constitutes a housing of the functional device. The control device includes a control case, which constitutes a housing of the control device. A first connector is partially exposed to an outside of the functional case. A second connector is partially exposed to an outside of the control case. The first connector is coupled to the second connector, so that the functional device is electrically connected to the control device without a harness between the functional case and the control case.

Steering wheel

The present invention provides a light coupler and a manufacturing method thereof. The light coupler of the invention includes a plurality of light input terminals, a plurality of light output terminals, a plurality of half mirrors, and an optical wave guide connecting the plurality of the light input terminals, the plurality of the light output terminals and the plurality of the half mirrors. The optical wave guide has kinked line shape and each of the plurality of half mirrors is placed at a respective corner of the kinked line shape. Especially, the kinked line shape includes a polygon network.

Light coupler and manufacturing method thereof

The optical branching-coupling device having a self-written optical waveguide core is formed without using half mirrors. In the optical branching-coupling device, three POFs are inserted into a housing having an approximately D-shaped sidewall. An approximately semi-columnar region V in the housing was filled with an uncured liquid light-curing acrylic resin. A laser beam was introduced from one of the POFs, and a cured material was formed of the end face of the POF. The diameter was equal to the core diameter of the POF. The cured material grew, resulting in the cured material reaching the end face of another one of the POFs, thereby forming an optical waveguide core. Next, a laser beam was introduced from the end face of the last one of the POFs. The cured material grew, resulting in a connection with the optical waveguide core, thereby forming the optical waveguide core.

Optical branching-coupling device, and manufacturing method and optical module of the same

There is provided a method of manufacturing an optical module comprises a component fixing step in which an optical waveguide and at least one optical device are detachably held by a fixing member capable of holding an uncured light curable resin in a required position, and a core forming step in which light of a wavelength for curing the light curable resin is emitted from the leading end of the optical waveguide to the light curable resin uncured and thus the light curable resin is cured to form a shaftlike core. According thereto, the optical waveguide and the optical device are connected by the core.
