Abstract: An electrical device such as a power control apparatus comprises a case and at least one electrical component accommodated in the case. The case has a flow path for a cooling fluid. The flow path is formed between a bottom portion and a cover. The flow path is elongated generally along a U shape. The bottom portion and the cover are joined by welding. The cover is formed with protruding portions protruding into the flow path. The protruding portions have shapes to reduce stress concentration on welding portions. A stress caused by a pressure of the cooling fluid may acts on a distal end formed inside of the U shape in a concentration manner.

Abstract: A heat treatment apparatus includes processing chambers into which microwaves with an effective wavelength of ?g are introduced. The processing chambers are arranged parallel to each other. The length from an inner wall surface of one end of each processing chamber in the lengthwise direction to an inner wall surface of the other end thereof is m×?g/2 (m being a positive integer). An antenna sending microwave oscillation into the processing chambers is separated by ?g/4+p×?g/2 (p being a positive integer including 0) from the inner wall surface of the end part in the lengthwise direction of each processing chamber. The processing chambers are disposed to be offset by ?g/(2×n) (n being the number of the processing chambers) from each other in the lengthwise direction, when the processing chambers are seen to overlap with each other in a perpendicular direction to the lengthwise direction of each processing chamber.

Abstract: A method for manufacturing an externally circular precursor lens that is processed into a rim-shaped lens includes inputting processing data to specify the shape of the rim-shaped lens, and processing a material block based on the processing data so as to manufacture a precursor lens. An elliptical virtual rim surrounding the precursor lens manufactured at that time is imaginarily set, and is processed based on the processing data up to that range, and, outside the virtual rim, an amount of sag is changed to secure the edge thickness of the precursor lens. This method for manufacturing a precursor lens for a rim-shaped lens reduces an excessive load imposed on a processing tool during processing, allows the precursor lens to be processed into a rim-shaped lens while satisfactorily maintaining its edge thickness without the lack of the edge of the precursor lens, and results in a thin lens.
