    摘要： A semiconductor laser device is formed by laminating optical confinement layers and active layers so as to dispose each of said active layers between said optical confinement layers, wherein one of the opposite ends perpendicular to the junction planes of the individual layers in the semiconductor multi-layer film is coated with a low reflection film and the other of the ends is coated with a high reflection film, wherein the low reflection film is an Al2O3 film having a resistivity of 1×1012 &OHgr;·m or more, preferably 1×1013 &OHgr;·m or more, and having a stoichiometric ratio composition, which is deposited by, for example, an electron cyclotron resonance sputtering process. The present invention has realized a semiconductor laser device exhibiting a prolonged duration of operating life and having high driving reliability, which is advantageous in that a catastrophic optical damage hardly occurs and a lowering of the optical output after driving at a constant current is suppressed, and thus, it is preferably used as an optical transmitter for the optical communication.

    摘要： The present invention is structured in such a manner that, when multivalued pixel data which constitutes a multivalued image are supplied, a predetermined number of interpolated pixel data are generated and inserted between the supplied and successive pixels. At this time, the gradient of each of the interpolated pixels is calculated and determined in accordance with the gradient of the supplied neighboring multivalued pixels. Thus, the image is recorded on a recording medium in accordance with image data including the interpolated pixel. As a result, print information processed so as to be printed by a low resolution printer can be printed with the same size and high quality as when printed by a high resolution printer according to the present invention.

    摘要： A lock slider for slide fastener has on a slider body in a lock slider for slide fastener, an operating-lever-receiving seat is formed on a slider body. An operating lever has a grip at one end, and a locking pawl at an intermediate position off to the other end, which pawl is angularly spaced by 90.degree. from the grip. With the lever, a resilient plate, an axle of a pull tab and attachment plate placed one over another in the seat, an axle of a pull tab placed over the resilient plate, the attachment plate is fixed to the seat in such a manner that the lever is angularly movable by about 90.degree.. The grip is turned in such a manner that the resilient plate presses the cam so as to insert the locking pawl between the coupling elements to lock, and when the grip is raised, the locking pawl is retracted from between the coupling elements so that the slider can slide.
