Abstract: A sanitary washing apparatus is provided according to one aspect of the invention, where the sanitary washing apparatus includes: a washing nozzle having a water discharge port, where the washing nozzle is configured to wash a body of a user by squirting water from the water discharge port; and a casing capable of storing the washing nozzle. The washing nozzle is configured to change from a stored state to an advanced state while transitioning to an orientation having a greater angle of an axis of the washing nozzle with respect to a horizontal plane, where the washing nozzle is stored in the casing in the stored state, and the washing nozzle is configured to wash the body in the advanced state.

Abstract: An optical writing device includes a light source, an optical deflector that deflects and scans light from the light source, a pre-deflector optical system that guides the light from the light source to the deflector, a post-deflector optical system that guides the scanned light to a target surface, a cover covering the deflector and including a first opening and a second opening provided at different positions, and a housing housing these optical elements. Light traveling from the light source to the deflector and the light scanned by the deflector are transmitted through the first opening but not through the second opening. During the rotation of the deflector, a forced inflow of air flowing from outside to inside the cover is generated in the first opening, and a discharged airflow flowing from inside to outside the cover is generated in the second opening.

Abstract: Provided is a dielectrophoresis apparatus with which it is possible to handle (move, stop, separate and sort, etc.) a dielectric particle utilizing dielectrophoresis and to measure dielectrophoretic force. The interior of a dielectrophoresis device that includes a case having a flat top or bottom surface is filled with a dielectric solution S and accepts introduction of a small target body (particle) P comprising a dielectric. A non-uniform alternating electric field is formed within the case. By tilting the case (through an angle ?pitch or other direction), rotating the case in an inclined plane (through a rotational angle ?yaw) or adjusting the voltage and frequency of the alternating electric field, imbalance or balance is produced between a dielectrophoretic force FDEP that acts upon the small body and a force FG sin ?pitch ascribable to gravity and buoyancy, thereby enabling the small body to be moved and stopped.
