摘要： An optical writing apparatus including a semiconductor laser having plural light emitting elements and a single light-receiving element and plural semiconductor laser drive controlling devices. The plural light emitting elements in the semiconductor laser array are driven such that an optical writing operation at a same time per each of plural lines is performed. A commonly used LD drive controlling circuit drives the LD array. An output timing-determining device outputs a switch changing-over signal to either one of respective changing-over switches in a changing-over switch circuit. After an operational delay time of the changing-over switch elapses, an APC signal is output to an APC control section of the LD drive controlling circuit connected to a negative feedback loop formed by a changing-over operation of the changing-over switch circuit. After the completion of the APC operation, the outputting of the switch changing-over signal to the changing-over switch is stopped.

摘要： In fabricating an MFIC by mounting a semiconductor chip on a substrate having a microstrip line by MBB bonding, a benzocyclobutene (BCB) film is used as a dielectric film of the microstrip line. By providing a means for preventing the deformation, peeling, and cracking of the BCB film during the fabrication process, the thickness of the dielectric film is held substantially equal even after flip-chip mounting, which reduces impedance fluctuations.

摘要： Each of a pair of magnetic core halves includes a substrate and a thin magnetic metal film formed on the substrate. The substrate is notched with a winding groove. The pair of the magnetic core halves are integrally bonded to each other so that a gap filling film is formed between the facing surfaces of the thin magnetic metal films. The zero depth position of the magnetic gap which is determined by the length of the facing thin magnetic metal films is offset to a magnetic recording medium sliding surface of the magnetic head from the notching start position of the winding groove on the side of the magnetic gap. Hence, the shape of the thin magnetic metal film exposed on the magnetic recording medium sliding surface is maintained constant from the initial position to the depth zero position.

摘要： An exposing unit optically writes respective color-separated image data on a photosensitive drum to form a latent image by using both a forward direction scanning and a backward direction scanning. A writing control unit outputs input pixel data to the exposing unit a plurality of times for enlarging and printing an input image. The writing control unit includes an output unit that outputs a main-scanning effective gate signal of dot period lengths of common multiples of all available enlargement ratios; and a suppressing unit that suppresses an output of a pixel signal to an outside of a printing range.
