摘要:
A system for spotting moving objects based on a plurality of artificial satellites including: a step of taking images at the same point in time by using imaging devices respectively mounted on at least two units of artificial satellites located separately from one another of which the positions can be defined at every moment in time; a step of discriminating a large number of stars at infinity and a small number of moving objects located near the earth through a synthetic processing by superimposing upon one another at least two images of spots obtained from the image taking at the respective satellites; and a step of specifying the positions of the discriminated moving objects from data of images forming positions of the moving objects on the basis of the large number of stars at infinity.

A method for producing graphene includes: a pretreatment process of drying and pulverizing a vegetable material to obtain a carbon source; a carbonization process of carbonizing the carbon source to obtain a carbide; and a purification process of removing an impurity containing silica from the carbide obtained in the carbonization process, wherein the carbonization process including a heating process of supplying an inert gas into a chamber and heating the carbon source in the chamber in a plasma atmosphere.
摘要:
A heat sink comprising a plurality of cooling fins and a plurality of spacers. Each of the cooling fins is formed to assume a shape of letter L by bending a lower end of a metallic plate so that the bent portions serve as heat-collecting portions, and the spacers are provided between adjoining cooling fins for maintaining intervals between the cooling fins and for pressing the heat-collection portions of the cooling fins to the heat-radiating surface of an electronic component. The cooling fins and spacers are connected by connecting rods piercing through portions at which the fins and spacers are overlapped.

A magnet pump includes a synthetic resin casing, divided into a front casing and a rear casing and configured to internally form an impeller housing chamber and a magnet can housing chamber contiguous thereto, having an inlet and an outlet for a target fluid to be transferred. The casing forms an eddy chamber at a position for dividing the front casing and the rear casing along the outer rim of the impeller housing chamber to surround the outer rim of the impeller. The eddy chamber has overhangs formed at an entry of the eddy chamber hanging over from both sides in the rotational-axis direction of the impeller.
