Abstract:
A vehicle headlamp includes: a lamp unit including an upper support shaft and a lower support shaft that are coaxially formed each other; a bracket adapted to support the lamp unit via a ball bearing in the upper support shaft and via a slider in a lower shaft support portion; an actuator including a mechanism portion adapted to drive the lower support shaft of the lamp unit, the actuator being movable in a forward and backward direction with respect to the bracket; and a spring portion that is fixed to the bracket, and is adapted to compress a tip end of the upper support shaft.
Abstract:
Provided is a solid electrolyte material which, while maintaining high oxygen ion conductivity, minimizes the decomposition of scandia caused by impurities such as silicon in the fuel gas, and improves intergranular strength in order to eliminate intergranular fracture caused by crystalline modification. The solid electrolyte material is a zirconia solid electrolyte material having scandia and a lanthanoid oxide and/or yttria dissolved therein, and has alumina further added thereto.
Abstract:
A temperature adjustment member is arranged to control temperature of a reformer independently of temperature of a fuel cell module. The reformer is structured as a three-fluid heat exchanger into which a fluid is introducible whose temperature is higher or lower than exhaust-gas temperature of the fuel cell module. Then, the temperature of the reformer is controlled independently of operation temperature of the fuel cell by introducing the higher-temperature or lower-temperature fluid into the reformer. Also, a high-temperature or low-temperature gas is mixed with the module's exhaust gas, thereby adjusting temperature of the exhaust gas itself. This also controls the temperature of the reformer independently of the operation temperature of the fuel cell.
Abstract:
A vehicle headlamp is provided with: a main reflector having a convergent reflecting surface; a semiconductor-type light source; a projecting lens; an auxiliary reflector having a parabolic reflecting surface; a shade and a light shading member that are structured integrally with each other; and a switching device. By means of the switching device, the shade and light shading member, which are structured integrally with each other, are switched and positioned in a first location and a second location, thereby allowing light distribution patterns for high and low beams to be switched and illuminated toward a forward direction of a vehicle. As a result, the vehicle headlamp becomes capable of achieving downsizing, weight reduction, power saving, and cost reduction.
Abstract:
A vehicle headlamp is provided with: a fixed reflector having reflecting surfaces, a respective one of which is made of a parabola-based free curved face; movable reflectors having reflecting surfaces, a respective one of which is made of a parabola-based free curved face; and semiconductor-type light sources, a respective one of which has a light emitting chip shaped like a planar rectangle. When the movable reflectors are positioned in a first location, a light distribution pattern for low beam is obtained on the reflecting surfaces of the fixed reflector. When the movable reflectors are positioned in a second location, light distribution patterns for high beams are obtained on the reflecting surfaces of the fixed reflector and the movable reflector. As a result, the vehicle headlamp enables downsizing, weight reduction, power saving, and cost reduction.

Abstract:
A vehicle headlamp is provided with semiconductor-type light sources, lenses, a reflector, light shading members, prism members, and a switching device. When the light shading members are positioned in a first location by means of the switching device, a light distribution pattern LP for low beam, having one or more cutoff lines, is illuminated. In addition, when the prism members are positioned in the first location by means of the switching device, a light distribution pattern HP for high beam is illuminated. As a result, the vehicle headlamp can achieve downsizing, weight reduction, power saving, and cost reduction.

When the movable reflectors are positioned in a second location, light distribution patterns for high beams are obtained. When the movable reflectors are positioned in a third location, light distribution patterns for daytime running light are obtained. As a result, the vehicle headlamp can achieve downsizing, weight reduction, power saving, and cost reduction.
Abstract:
A vehicle headlamp has a projector-type lamp unit. The lamp unit has a lens holder. An external surface of the lens holder is formed in a convex circular-arc shape, centering on a rotation axis. As a result, even if the lamp unit rotates about the rotation axis, the clearance between the internal surface at the edge of an opening in an inner panel and the external surface of the lens holder is maintained substantially constant at all times.
