A vehicle detecting system includes image taking means for taking an image of the surroundings of a subject vehicle, vehicle detecting means for detecting a vehicle from the taken image, and lateral-position detecting means for detecting a lateral position of the vehicle in the taken image. The lateral-position detecting means vertically divides, into a plurality of sections, a region set in a portion of the taken image in which an image of the vehicle is included or is presumed to be included. The lateral-position detecting means calculates average brightnesses of pixels belonging to pixel columns vertically extending in the sections and having a width corresponding to one pixel or a plurality of number of pixels. The lateral-position detecting means calculates differences in average brightness between pixel columns adjacent in a lateral direction, and detects the lateral position of the vehicle on the basis of absolute values of the differences.

A heavy oil is hydrorefined using a hydrorefining catalyst. A spent hydrorefining catalyst whose activity has decreased is heat treated (S1) and pulverized to obtained a regenerated powder (S2). This regenerated powder is fractionated according to its metal content (S3), formed (S6), dried (S7), and calcined (S7) to manufacture a regenerated catalyst whose volume of pores with a diameter of 50 to 2000 nm is at least 0.2 ml/g, and whose volume of pores with a diameter over 2000 nm is no more than 0.1 mL/g. Using this regenerated catalyst, a heavy oil containing at least 45 wt ppm vanadium and nickel as combined metal elements is hydrodemetalized, and the vanadium and nickel are recovered from the used regenerated catalyst (SS1). Through hydrorefining, the metal components are recovered more efficiently, and the spent catalyst can be reused to manufacture a regenerated catalyst that exhibits high reaction, activity.

A dustproof suit for a clean room is provided. The dustproof suit includes a garment, a pair of inner pants disposed inside the garment, a hood detachably mounted on the garment and a suction unit attached to the garment for decompressing an interior of the garment. The suction unit consists of a suction belt arranged inside the garment and an air cleaner arranged outside the garment so as to associate with the suction belt. The suction belt is provided with a hollow passage and a plurality of suction holes communicating with the hollow passage. In operation, owing to sucking operation of the air cleaner, air in the garment is firstly sucked into the suction belt through the suction holes. Then, dust contained in the air is then filtrated by the air cleaner and sequentially discharged to an outside of the garment.
