摘要:
There are provided a film forming equipment component having a structure in which an deposited film d formed on the component can be separated from the component for a time period shorter than the prior art to reduce damage due to a cleaning fluid S, and a method of cleaning such a component. A metal film layer 2 electrochemically less noble than the matrix metal material 1 of the aforementioned component is formed on the surface of the matrix metal material 1 through thermal spraying, vapor depositing, sputtering, laminating or other process. Alternatively, a second metal film layer 3 electrochemically more noble than the aforementioned matrix metal material 1 is formed on the surface of the metal film layer 2 through said thermal spraying or other process. Thus, a local cell is formed between the metal film layer 2 and the matrix metal material 1 or the second metal film layer 3. Therefore, the deposited film d can be separated from the matrix metal material 1 for an extremely shortened time period, without damaging the matrix metal material 1 itself from the cleaning fluid S.

In An Al composite material collapsible in the presence of moisture, the external surface of small pieces or powder constructed from a single or a plurality of crystalline grains of Al or an Al alloy is covered with a film of a low melting point metal or alloy selected from the group consisting of In, Sn, combinations of In and Sn, and alloys thereof. The content of the foregoing low melting point metal or alloy ranges from 0.1 to 20% by mass on the basis of the total mass of the composite material. A material obtained by adding a low melting point metal in an amount specified above to, for instance, Al and then fusing and melting the resulting mixture is quenched and solidified within a non-oxidizing atmosphere to thus form an Al composite material. An Al film, an Al spray-coated film and Al powder can be prepared from the foregoing Al composite material. A component member for a film-forming chamber is also provided, which is provided with a water-collapsible Al film on the surface thereof. Film-forming operations are continued over a long period of time using the component member for a film-forming chamber provided with the water-collapsible Al film and then film-forming materials can be recovered from the component member on which the film-forming materials are deposited in a substantial thickness.

摘要:
A reflected light measuring apparatus including an illumination system and a light receiving system which receives reflected light from a measuring area of an object illuminated with measuring light projected from the illumination system. The illumination system projects the measuring light with a prescribed angular width onto each point in the measuring area. The illumination system and the light receiving system project the measuring light onto the measuring area and receive the reflected light via a telecentric optical system.
摘要:
An illumination system comprises a light source unit, a condenser lens, and a lens for constructing a telecentric optical system, and projects measuring light onto a specimen to be measured, from an angle tilted by a prescribed angle relative to the normal to the specimen. A light receiving system is an optical system comprising the lens, a light receiving lens, and a light receiving sensor and, of the reflected light produced by reflection of the measuring light, the light receiving system receives reflected light rays reflected in a direction whose angle to the normal to the measuring surface is 0°. In this way, the telecentric optical system is constructed by placing the lens in the light paths of the illumination system and the light receiving system; with this configuration, the projection angle of the measuring light to the curved specimen and the receiving angle of the reflected light from the curved specimen, respectively, can be made the same within the curved surface of the specimen.
