Abstract: A semiconductor device includes a semiconductor chip, a circuit board, a heat releasing plate, an adhesive member, and a conductive member. The circuit board transmits a signal of the semiconductor chip. The heat releasing plate has the semiconductor chip disposed thereon, and has an opening in a region on the outer side of a semiconductor chip placement region that is a region in which the semiconductor chip is disposed. The adhesive member is disposed in a region on the outer side of the opening on a different surface of the heat releasing plate from the surface on which the semiconductor chip is disposed, and bonds the circuit board and the heat releasing plate to each other. The conductive member connects the semiconductor chip and the circuit board to each other via the opening.

Abstract: A photographic film container made of a metallic material comprising: a metallic support; an antirust coating comprising no hexavalent chromium on at least one side of the metallic support; and a paint coating on the antirust coating, wherein when the metallic material is subjected to the bend test of 180 degrees using a mandrel having a diameter of 2 mm in accordance with JIS-K-5600-5-1 and the bent portion of the metallic material is evaluated in accordance with JIS-K-5600-8-1, the flaking grade of the coatings of the metallic material determined by JIS-K-5600-8-5 is within 1 to 4 grade.

Abstract: In a high accuracy blast processing method of the present invention which is a blast processing method for processing a substrate by injecting an injection material from a nozzle by compressed air, injection of the injection material is either intermittent injection for repeating the injection and injection stop at short intervals or a combination of the intermittent injection and continuous injection. By doing so, even if a processing progresses, processing efficiency is not deteriorated and a non-processing target region is not damaged even without using a mask. A high accuracy blast processing apparatus of the present invention consists of a nozzle unit forcedly feeding the injection material to the nozzle by the compressed air and a work table moving the substrate horizontally and vertically. A solenoid valve for injecting and stopping the injection material and a control unit outputting an intermittent operating signal to the solenoid valve are connected to the nozzle unit.
