Abstract: The purpose of the present invention is to provide a light guide plate with which it is possible to prevent light unevenness and improve appearance, and a light emitting device using the same. A light guide plate (11) is provided with: a light incidence surface (12) on which light is incident; a light emission surface (13) which faces the light incidence surface (12) and from which light incident from the light incidence surface (12) is emitted; and a flat plate-shaped light guide member (14) which guides the light incident from the light incidence surface (12) to the light emission surface (13).

Abstract: Provided is a switch which achieves cost reduction and reduction in man-hours required for assembly. This switch comprises: a casing having a wall portion; two rubber domes that are provided to face each other with the wall portion sandwiched therebetween and give a click feeling; a lever main body having a retaining portion that is provided to be rotatable about an axis X with respect to the casing and retains the rubber domes and a contact portion that is in contact with a detector switch. The inside surface of the retaining portion is formed into an arch shape with the wall portion put therein, the two rubber domes are provided integrally with an elastic sheet member, and the sheet member is bent along the arch shape of the inside surface and retained by the retaining portion.

Abstract: This air-conditioning unit includes a heat exchanger that exchanges heat between air and a coolant, a blower, and an air outflow part. The heat exchanger includes a plurality of tubes in which the coolant flows, an inlet header, an outlet header, and a fin. The inlet header includes: a low-temperature-side coolant inflow part into which coolant that has a relatively low temperature can flow; and a high-temperature-side coolant inflow part into which coolant that has a relatively high temperature can flow. The low-temperature-side coolant inflow part and the high-temperature-side coolant inflow part are offset from each other in the direction of the flow of air that passes through the heat exchanger and in an intersecting direction that intersects the direction of the flow of air.

Abstract: This air conditioning device for a vehicle has: an indoor condenser; an indoor evaporator; a first expansion valve; a second expansion valve; a refrigerant line; an expansion valve control detector; and a controller. The expansion valve control detector is constituted by: only one temperature sensor that detects the temperature of refrigerant in an inter-expansion valve line of the refrigerant line; and only one pressure sensor that detects the pressure of the refrigerant in the inter-expansion valve line. During a cooling operation, the controller issues, to the first expansion valve, an opening command corresponding to a state quantity of the refrigerant that has been detected by the expansion valve control detector, and during a heating operation, the controller issues, to the second expansion valve, an opening command corresponding to a state quantity of the refrigerant that has been detected by the expansion valve control detector.

Abstract: Provided are a heat exchanger that makes it possible to supply air of an appropriate temperature to a plurality of blowing ports of an air-conditioning unit, an air-conditioning unit that comprises the heat exchanger, and an air conditioner. This air-conditioning unit 10 comprises a heat exchanger 20 that exchanges heat between air and a coolant, a blower 11, and an air outflow part 12. The heat exchanger 20 comprises a plurality of tubes 21 in which the coolant flows, an inlet header 23, an outlet header 24, and a fin 22. The inlet header 23 includes: a low-temperature-side coolant inflow part 231 into which coolant that has a relatively low temperature can flow; and a high-temperature-side coolant inflow part 232 into which coolant that has a relatively high temperature can flow.

Abstract: A control device controlling a vehicular air conditioning system includes a defrosting operation control unit performing a defrosting operation in a refrigerant system when an outflow refrigerant temperature of an outdoor heat exchanger has become equal to or lower than a defrosting condition threshold value, a defrosting operation release instruction unit outputting a defrosting operation release instruction when the outflow refrigerant temperature has become equal to or higher than a defrosting release condition threshold value, and a vehicle information acquisition unit acquiring at least one of a position and a speed of a vehicle in which the vehicular air conditioning system is mounted. The defrosting operation release instruction unit outputs a defrosting operation release instruction even when the outflow refrigerant temperature is lower than the defrosting release condition threshold value in a case at least one of the position and the speed of the vehicle satisfies a predefined condition.

Abstract: A dial type switch mechanism is developed in which an installation space can be made as small as possible. In a dial type switch mechanism (10) furnished with a push type switch part provided in its center, and a dial switch part which operates a dial fitted around the push type switch part, there are provided: a substantially cylindrical dial knob (21), in the center of which a cavity is provided for the push type switch part to be installed; a ring-shaped joint ring (23), which is supported such that it can rotate freely relative to a front panel (6) and connects and rotates together with the dial knob (21); and a rotary bracket (24), which is joined to the joint ring (23), and in which a switch rotation shaft (24b) that operates the dial type switch part is connected together with a ring-shaped member (24a) via an arm (24c).
