Abstract: A mirror device includes a mirror including a main body portion having a reflection surface that reflects display light, and a rotating shaft protruding from a first side wall of the main body portion, and a driving member that includes a motor including an output shaft arranged parallel to the rotating shaft, and neighboring the rotating shaft in a direction orthogonal to a rotation axis line of the rotating shaft, a first gear portion coupled to the output shaft, and a second gear portion engaged with the first gear portion, and coupled to the rotating shaft, and rotates the mirror by transmitting rotation of the output shaft of the motor to the rotating shaft via the first gear portion and the second gear portion.

Abstract: A vehicle display device includes a housing including an opening, an image display device that outputs display light of an image, and a mirror that includes a main body including a reflective surface that reflects the display light toward the opening and is rotatable around a rotation axis. The mirror includes a first and a second ribs that extend along a first direction, and face each other in a second direction. The first rib is formed as a rib closest to a side of the upper end on the back surface, the second rib is formed as a rib closest to a side of the lower end on the back surface, and a central region between the first and the second ribs on the back surface is formed as a flat curved surface, at least a part of which extends from the first rib to the second rib.

Abstract: A water heater includes a burner, a heat exchanger, a passing water quantity control unit, a temperature detection unit, and an operation control unit. The operation control unit performs the output hot water temperature control by configuring the passing water quantity control unit to have a predetermined passing water quantity that is further restricted compared with a predetermined water quantity, and upon confirmation that a predetermined release condition of the passing water restriction is satisfied, executes the passing water control in which the passing water quantity is returned back to the predetermined water quantity by gradually releasing the passing water restriction, and the operation control unit, when a predetermined undershoot factor of the detected temperature is confirmed while the passing water quantity is returned back to the predetermined water quantity, temporarily stops the release of the restriction of the passing water quantity until the undershoot factor is resolved.

Abstract: An optical network unit (ONU) includes a plurality of media access control (MAC) processing units and a storage unit which stores grouping information for grouping the plurality of MAC processing units.

Abstract: According to one embodiment, there is provided a lighting fixture including a light source module and a support unit. The light source module includes a case which has the shape of a tube extending in a first direction, includes an opening, a substrate on which plural light sources are provided, and which is held in the case so that the plural light sources face the side opposite to the opening, and a mounting plate which is held by the case while being inserted between the opening and the substrate and is thermally connected to the substrate. The support unit includes a support plate which supports the light source module, and a frame which surrounds the outer edge of the support plate. An end portion of the light source module in the first direction is covered with the frame. The respective light sources are not covered with the frame.

Abstract: A communication system in which plural portable communication terminals present in a relatively narrow area are safely and securely matched and connected to each other by a simple operation, to exchange various types of information therebetween. When front sides of smartphone terminals are bought close to each other, either one of proximity sensors reacts or detects first. The reacted smartphone terminal allows a bottom speaker to generate ultrasound (e.g., 20 Khz), allows a back LED to light up, and stores the time at which the ultrasound has been detected. When the smartphone terminals are distanced from each other, both of the smartphone terminals stop detecting ultrasound by bottom microphones, and transmit a first reception time information and a second non-reception time information to a web server. The web server groups together and connects the two smartphone terminals, based on the received first time and second time.

Abstract: An adapter includes a tabular body configured to close the existing attachment hole opened in the ceiling in a state in which the existing lighting equipment is removed and a positioning convex section protrudingly provided on the front surface of the tabular body on a side remote from the ceiling. A part of a chassis of lighting equipment to be attached anew is partially projected toward the rear surface of a substrate mounted with a light-emitting element and forms a contact convex section. A fitting concave section is formed on the rear side of the contact convex section. The positioning convex section is fit in the fitting concave section formed on a rear side of the contact convex section, whereby the lighting equipment to be attached anew is positioned with respect to and combined with the adapter and attached to the ceiling together with the adapter.

Abstract: A spiral heat-transfer pipe for heat exchange provided in a heat exchanger includes: an upstream heat-transfer pipe section disposed on an upstream side of a flow path of an external fluid flowing outside the spiral heat-transfer pipe; and a downstream heat-transfer pipe section disposed on a downstream side of the flow path. Each of the heat-transfer pipe sections is disposed so as to extend in a direction crossing the flow path of the external fluid. Each of an axis of the upstream heat-transfer pipe section and an axis of the downstream heat-transfer pipe section is tilted with respect to a horizontal plane. Also, the axis of the upstream heat-transfer pipe section crosses the axis of the downstream heat-transfer pipe section.

Abstract: A gas monitoring apparatus includes a sample introducing portion, a measurement portion, an ionization portion, a mass analysis portion, a data processing portion and a display. The sample introducing portion introduces a sample gas including an object material to be measured. The measurement portion measures a concentration of a predetermined coexisting material, which coexists with the object material in the sample gas. The ionization portion ionizes the sample gas. The mass analysis portion analyzes mass of an ion produced by the ionization portion. The data processing portion analyzes signals detected by the mass analysis portion to calculate a concentration of the object material. And the display displays results of analysis conducted by the data processing portion. The data processing portion includes an adjustment portion which adjusts the concentration of the object material according to the concentration of the predetermined coexisting material.
