Filed: 1989-09-20
Abstract: PURPOSE:To shorten a document processing time in a double-sided document mode by feeding a double-sided document to an exposing part from a waiting position when the document in the exposing part is fed to an eject part. CONSTITUTION:An exposing optical system exposes the document in the exposing part a prescribed number of times, and a prescribed number of copies for the second surface of the document are obtained. While the document sent through a turning-over path is exposed, a next document is sent from a document placing part 1 to the waiting position in the same manner as in a single- sided document mode. After exposure, the document in the exposing part is turned in the direction of an arrow from a feed roller 6 to a double-sided paper eject roller 15, and is ejected to a double-sided document receiving tray 16. Simultaneously, the document in the waiting position is sent to the exposing part. After that, the first surface of the document sent from the waiting position to the exposing part is exposed, following which the document is turned over in a turning-over path, and is again placed in the exposing part. The second surface of the document is exposed and processed.

Title: Surface treating method of semiconductor substrate evaluation
Inventor: KATO HIROTAKA
IPC: G01N21/00
Filed: 1994-09-14
Abstract: PURPOSE: To evaluate the degree of heavy metal contamination of a semiconductor substrate in a shorter time by an SPV method than that by a conventional method where a semiconductor substrate must be left to stand at least for a week because an SPV value is unstable after the semiconductor substrate is subjected to a surface treatment. CONSTITUTION: An epitaxial layer is removed by etching with mixed acid, and a semiconductor substrate where a bare silicon surface is exposed is cleaned with buffered hydrofluoric acid and successively subjected to an SC-1 cleaning process. When the semiconductor substrate is left to stand for two hours or so after a treatment, an SPV value becomes stable enough, that is, the rate of change is about 5%, and the diffusion length of minority carrier is capable of being accurately measured. Therefore, a semiconductor substrate evaluation method of this constitution is markedly lessened in lead time as compared with a conventional one.

Abstract: PURPOSE:To easily obtain a natural pottery-like surface pattern, by molding an FRP molded product having an embossed pattern formed to the surface thereof from a sheet-molding compound and applying paint to the surface thereof to allow the same to naturally flow down before solidification. CONSTITUTION:At first, a sheet-molding compound is subjected to compression treatment under heating to form an FRP molded product 1 having an embossed pattern formed to the surface thereof. If necessary, joints 2 are formed to the surface of the molded product to such a degree that paint does not flow down and, thereafter, paint 3 such as polyurethane resin paint or epoxy resin paint is applied to the embossed pattern. After the paint is applied, the paint film is allowed to stand until the surface thereof loses stickiness and the paint is allowed to naturally flow down under its own wt. Hereupon, the paint flows down from protruded parts to be accumulated in recessed parts and a shade of color is generated. If the coated product is introduced into a heating oven in this state to heat and solidify the film, the desired FRP molded product is obtained.
