Filed: 1979-03-13
Abstract: PURPOSE:To decrease the higher harmonic distortion caused by the nonlinearity of the driving force of the speaker sound pressure, by forming the voice coil with plural number of conductors connected in parallel and at the same time decreasing the resistance value of each conductor less toward the edge part than the center part. CONSTITUTION:The voice coil in which voice coil part 11a is formed with print conductor 11 at coil bobbin 7 is provided within the magnetic circuit gap formed by magnet 3, plate magnetic pole 4, center pole 2 and yoke 1. For the voice coil of such structure, part 11a formed with conductor 11 is distributed on film 10 wound round the outer circumference of bobbin 7, and the width of conductor 11 is increased gradually from center part C toward common conductor parts 11b and 11b' at the edge part. At the same time, the resistance value of part 11a is decreased gradually from part C toward the edge part. As a result, the compensation is possible to the higher harmonic distortion caused by the nonlinearity of the driving force of the speaker sound pressure.

Title: Electrophotographic sensitive body and its manufacture
Inventor: KONUMA SHIGEHARU
IPC: G03G5/08
Filed: 1983-02-25
Abstract: PURPOSE:To improve reproducibility of electrophotographic characteristics, sensitivity to He-Ne laser beams, and heat resistance and to extend a life by making the alloy element concn. of the Te-contg. layer of an Se type photosensitive body almost constant in the film thickness direction. CONSTITUTION:The alloy element concn. of the Te-contg. layer (Te-Se alloy layer) 4 of an Se type photosensitive body formed on a conductive substrate 1 is made almost constant in the film thickness direction. The Se photosensitive body is obtained by laminating an Se layer 3 and the layer 4 successively on the substrate 1. The layer 4 is formed by vapor deposition at a temp. about 100 deg.C higher than that of the liquid phase line of the binary constitutional diagram. The layer 4 thus formed makes the content of Te constant in the film thickness direction, enhances glass transition point and heat resistance, and extends its life, and further, eliminates scattering of electrophotographic characteristics, and enhances reproducibility. Since the Te content has correlation with, e.g. sensitivity to He-Ne laser beams, the sensitivity can be held at the optimum value by controlling the Te content.
