摘要： A particle detector comprises a light source, and a metal layer having an incident/reflective surface and a photoelectric surface opposing the incident/reflective surface. Incident light from the light source reaches the incident/reflective surface to excite near-field surface plasmon resonance photons at the photoelectronic surface. A particle deposited on the photoelectronic surface of the metal layer changes the near-field surface plasmon resonance photons to far-field scattered light. The particle detector further comprises a unit, provided above the photoelectric surface of the metal layer, for detecting the far-field scattered light.

摘要： A stepwise brake control is automatically performed when TTC obtained according to a relative distance and a relative speed between a vehicle and an object is lower than a predetermined value. For example, a brake force or a brake reduction speed is gradually increased over a plurality of stages in time series. Moreover, the affect of speed change control to the automatic brake control is removed. Alternatively, automatic brake control is supported by the speed change control. Alternatively, the friction coefficient state is estimated, and the brake force or the brake speed reduction is adjusted according to the estimated result. Alternatively, an auto-cruse function is invalidated at least the final stage. Alternatively, when the brake force or the brake speed reduction generated by a brake operation by a driver is greater than the brake force or the brake speed reduction generated by the brake control means, the brake operation by the driver is handled with a higher priority than the stepwise brake control.

摘要： A stepwise brake control is automatically performed when TTC obtained according to a relative distance and a relative speed between a vehicle and an object is lower than a predetermined value. For example, a brake pattern is modified according to the weight of a cargo and passengers. Alternatively, a driver selects a brake pattern of different (rapid or slow) speed reduction according to the type or weight of the passengers and cargo. Furthermore, the driver's psychology is acquired according to the alarm distance between vehicles set by the driver and an optimal brake pattern is selected according to this. Alternatively, an operation state of the vehicle by the driver is detected and if the detection result does not satisfy a predetermined condition, the set value of the TTC is increased. For example, the predetermined condition indicates the normal state of the driving by the driver. Alternatively, when the condition indicating the normality of driving by the driver is satisfied, the number of stages is reduced. Furthermore, brake control is adaptively performed according to the time required until collision.

Because of this features a driving unit of the dump truck (a generator for supplying power to the driving motor in the dump truck or a generating engine for driving the generator) is required only to have the performance sufficient for running on horizontal paths, which enables size reduction of the driving unit and as a result cost reduction of the dump truck. Further the assistant vehicle is connected to the dump truck and moves together with the dump truck, so that a freedom degree of the dump truck for a traveling path can substantially be improved.

摘要： The luminous efficiency of a nitride semiconductor device comprising a gallium nitride-based semiconductor layer formed on a dissimilar substrate is improved. An n-type layer formed on the substrate with a buffer layer interposed between them comprises a portion of recess-and-projection shape in section as viewed in the longitudinal direction. Active layers are formed on at least two side faces of the projection with the recess located between them. A p-type layer is formed within the recess. An insulating layer is formed on the top face of the projection, and on the bottom face of the recess. The n-type layer is provided with an n-electrode while the p-type layer is provided with a p-electrode contact layer. As viewed from the p-type layer formed within the recess in the gallium nitride-based semiconductor layer, the active layer and the n-type layer are located in an opposite relation to each other. As viewed from the side face of the recess, the active layer and the p-type layer are formed across the n-type layer.
