    Abstract: A technique for reducing the amount of particles adhering to a substrate with a simple structure is provided. A substrate processing apparatus is an apparatus for processing a substrate by ejecting a processing liquid from a nozzle. The substrate processing apparatus includes supply piping and an air-bubble capturing part. One end of the supply piping is connected via a first filter for removing particles to a tank of a processing-liquid supply part that supplies the processing liquid, and the other end of the supply piping is connected to the nozzle. The air-bubble capturing part is inserted at a position between the first filter and the nozzle in the supply piping, and captures air bubbles contained in the processing liquid. Pressure loss caused by the air-bubble capturing part is approximately equal to or smaller than pressure loss caused by the first filter.

  • Patent number: 8717563
    Abstract: A particle detector includes 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 photoelectric surface. A particle deposited on the photoelectric surface of the metal layer changes the near-field surface plasmon resonance photons to far-field scattered light. The particle detector further includes a scattered light detecting unit, provided above the photoelectric surface of the metal layer, for detecting the far-field scattered light.

  • Patent number: 7983828
    Abstract: 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.

  • Publication number: 20090102277
    Abstract: 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.
