Abstract: A load detecting device includes a load sensor and a sealing member encapsulating the load sensor. The sealing member includes a lower sealing member on which the load sensor is placed, an upper sealing member covering an upper face of the load sensor and joined to the lower sealing member, and an air pressure adjustment structure configured to cause an air pressure in an accommodation space, of the load sensor, formed by the lower sealing member and the upper sealing member to be approximately equal to an outside air pressure.

Abstract: A signal transmitting/receiving device includes: a light source part configured to emit transmission light; a light-receiving part having a photodetector configured to receive reception light; and a condenser mirror configured to condense the reception light on the photodetector. The condenser mirror has a through hole configured to allow the transmission light emitted from the light source part to pass therethrough and align an optical axis of the light source part and an optical axis of the condenser mirror with each other. A reflection surface of the condenser mirror has a shape obtained by cutting out a columnar body extending in an emission direction of the transmission light, with a spheroid whose rotation axis is a major axis.

Abstract: A load sensor includes: an electrically-conductive elastic body; an electrically-conductive member having a linear shape and disposed so as to cross the electrically-conductive elastic body; and a dielectric body disposed between the electrically-conductive elastic body and the electrically-conductive member. A width of the electrically-conductive elastic body in a longitudinal direction of the electrically-conductive member is changed such that a relationship between a load and a contact area between the electrically-conductive elastic body and the electrically-conductive member via the dielectric body becomes close to a linear relationship.

Abstract: A load sensor includes: a first base member and a second base member disposed so as to face each other; an electrically-conductive elastic body disposed on an opposing face of the first base member; an electrically-conductive member disposed between the second base member and the electrically-conductive elastic body; a dielectric body disposed between the electrically-conductive elastic body and the electrically-conductive member; and a component configured to change a contact area of the dielectric body in association with increase in a load, such that a form of change in capacitance between the electrically-conductive elastic body and the electrically-conductive member associated with change in the load becomes close to that of a straight line.

Abstract: An optical device includes: a light source part configured to project illumination light toward a sensing region; a photodetector configured to receive reflected light of the illumination light reflected on the sensing region; and a condenser mirror. The condenser mirror has a through hole through which the illumination light from the light source part passes and an optical axis of the light source part and an optical axis of the condenser mirror are aligned with each other. A reflection surface of the condenser mirror has a shape obtained by cutting out a columnar body extending in a projection direction of the illumination light, with a spheroid whose rotation axis is a major axis. The photodetector is disposed in a direction toward a first focal position of the condenser mirror. The sensing region is set in a direction toward a second focal position of the condenser mirror.

Abstract: A load sensor includes: two base members disposed so as to face each other; two electrically-conductive elastic bodies respectively disposed on opposing faces of the two base members; and a plurality of conductor wires disposed between the two electrically-conductive elastic bodies. The plurality of conductor wires are disposed under a condition that, when a diameter of each conductor wire is not greater than 0.3 mm, a gap between the plurality of conductor wires is not less than 0.6 mm, and when the diameter of each conductor wire is greater than 0.3 mm, the gap between the plurality of conductor wires is not less than twice the diameter of each conductor wire.

Abstract: A display device is provided and may include a light source that emits a light beam, a scanner that causes the light beam to scan, a movable screen in which an image is formed by transmitting the light beam from scanner, an optical system configured to project the image on a display medium, and a driver configured to cause the movable screen to reciprocate in moving directions. The image includes a first image and a second image. The movable screen reciprocates in a posture inclined with respect to the moving directions such that a second end of the movable screen is positioned closer to the scanner than a first end of the movable screen. The scanner forms the second image in the movable screen while the movable screen moves such that a forming direction of the second image is inclined with respect to a direction approaching the scanner.
