    摘要: A method for producing a semiconductor laser device includes the steps of: forming window layers on either one of a top surface of an internal structure or a reverse surface of a substrate and on light-emitting end facets of the internal structure; forming a reflection film on the light-emitting end facets; removing the window layer formed on either one of the top surface or the reverse surface by using an etchant which hardly etches the reflection film; and forming electrodes on the surface from which the window layer is removed by etching and on the other surface. Another method for producing a semiconductor laser device includes the steps of: forming window layers on light-emitting end facets of the bars; inserting the bars into an apparatus having openings for forming electrodes and a supporting portion for preventing a positional shift between the bars and the openings, and forming the electrodes on the top surfaces and the reverse surfaces of the bars; and cutting the bars into the chips.

    摘要: A surface electrode on a surface of a LED has a pad, and further, at least first-order branches linearly extending from the pad, second-order branches diverged and linearly extending from the first-order branches, and third-order branches diverged and linearly extending from the second-order branches. The pad out of the surface electrode is not in electrical contact with a underlying semiconductor layer, whereas the surface electrode and the semiconductor layer are in electrical contact with each other at ends of the highest-order branches. Also, the semiconductor layer is provided along a pattern of the surface electrode in a mesa shape. Thus, ineffective light emission underneath the surface electrode is relatively reduced so that external quantum efficiency can be improved, and moreover even shorter-wavelength light can be allowed to go out at high efficiency by omitting a current diffusion layer.

    摘要: A camera shutter includes a pair of spaced apart base plates supporting the various shutter components. At least one of the base plates is formed entirely of synthetic resin material which is electrically insulative and which possesses lubricating properties. The synthetic resin base plate has a set of tubular portions extending toward and connected to the other base plate and also has a set of shafts turnably supporting some of the shutter components, such as the control lever and control cam. The synthetic resin base plate also includes a hollow winding frame about which is wound a coil and in which is slidably inserted an armature to form an electromagnet for use in controlling the shutter operation. The use of a synthetic resin base plate dispenses with the necessity of separate lubrication and enables formation of a smaller shutter.
