Abstract: An optical position detection device includes a light receiving section receiving detection light reflected from a target object located in a detectable space through which detection light is radially emitted along an XY plane. The light receiving section includes a light receiving element and a concave mirror. A first cross section (XY cross section) of the reflective surface of the concave mirror is an arc, and a second cross section (YZ cross section) perpendicular to the first cross section is a quadratic curve. Therefore, in the in-plane direction of the XY plane, even light incident from an oblique direction with respect to the light receiving section is reflected by the concave mirror to the light receiving element. In the in-plane direction of the YZ plane, however, the range where the light reaches the light receiving element is limited via the concave mirror.

Abstract: An apparatus is provided for application to a waste heat reuse system that recovers and reuses engine waste heat, and for controlling the amount of waste heat based on a requested heat amount of a heat utilization request. In the apparatus, an overlap angle between a valve-opening period of an intake valve and that of an exhaust valve of the engine is controlled based on an engine driving condition. Ignition timing of the engine is controlled to fall on maximum-efficient timing that minimizes fuel consumption in a current engine driving condition. When a requested heat amount cannot be satisfied, overlap-increase control is performed to increase an overlap angle, and ignition advance control is performed to advance ignition timing with reference to a maximum-efficient timing that corresponds to the increased overlap angle. Waste heat amount of the engine is controlled with the overlap-increase control and the ignition advance control.
