摘要： In this brazing method, which brazes an insulating substrate and a top plate that configure an HV inverter cooler, the insulating substrate is disposed on the top plate with a brazing material layer therebetween, and then, by means of laser irradiation, laser welding is performed at an arbitrary plurality of positions at the joining section between the top plate and the insulating substrate, thus provisionally affixing the insulating substrate to the top plate. Thereafter, by means of heating and melting the brazing material layer, the insulating substrate is brazed onto the top plate with the plurality of laser-welded positions as the brazing start points. After brazing, a power semiconductor is joined onto the insulating substrate corresponding to the center portion of the region surrounded by the plurality of brazing start points.

摘要： An image recording apparatus which exposes a document image to a photosensitive material to obtain a reproduced image, comprising: first magnification setting means which automatically sets a first exposure magnification in which the document image is recorded on the overall surface of the photosensitive material; second magnification setting means which changes the first exposure magnification which has been set by the first magnification setting means to set a second exposure magnification where the first exposure magnification has been increased by a predetermined value so that margin is prevented from being formed at the periphery of an image which is recorded on the photosensitive material; and exposure means which exposes the document image to the photosensitive material, on the basis of the central portion of the document image, in one of the first exposure magnification which has been set by the first magnification setting means and the second exposure magnification which has been set by the second magnification setting means. As a result, when the photosensitive material is exposed in said second exposure magnification, the document image can be exposed to said photosensitive material in a larger size than that of said photosensitive material.
