Title: Copying paper separating method for electrostatic copying machine
Inventor: ABE TETSUYA
IPC: G03G15/00
Filed: 1981-05-23
Abstract: PURPOSE:To standardize the destaticizing current of copying paper by measuring electric potential formed by transferred copying paper, a photosensitive element, a gap between the copying paper and photosensitive element, and toner at periodically and changing a voltage to be applied to a discharging electrode according to the variation of the electric potential. CONSTITUTION:An electric potential measuring globe 3 is fitted between a transfer electrode 1 and a separation electrode 2. The electric potential between these electrodes is measured from the side of copying paper through the globe and the output voltage of a high voltage unit 6 which applies high voltage to the separation electrode is controlled by the measured electric potential through a relational operation circuit 5. Thus, the controlled differential current flowing from the separation electrode to the copying paper can be kept approximately constant independently of the variation of composite potential formed by the copying paper, a photosensitive element, a gap between the copying paper and photosensitive element, toner, etc., so that the copying paper is precisely separated from the photosensitive element and the quality of copies is prevented from being deteriorated.

Title: Toothed pulley with flange and manufacture thereof
Inventor: OYA MASAKIYO
IPC: F16H55/38
Filed: 1987-03-31
Abstract: PURPOSE:To obtain a toothed pulley which has large rigidity and no eccentricity by using a cup metal plate having one end surface opened, forming projected and recessed tooth portions on the inner and outer surfaces of the peripheral wall, and forming a flange integral with the peripheral edge of the end portion of the open side. CONSTITUTION:Tooth forms 2 are formed on the inner and outer surfaces of the peripheral wall of a cup metal plate 1, and a flange 4 is formed integral with the peripheral edge of the open end side. As the pulley is thus formed, rigidity is larger and eccentricity due to distorsion will not be produced, as compared with a pulley having no flange. As the flange 4 is integral with the pulley, the number of manufacturing processes is small so as to reduce the cost and remarkably improve the strength, as compared with a pulley having a separate flange. As the tooth form is formed by a die, after-working is not required and as the tooth form is contact-formed in a receive die, the dimensional accuracy is good.

Title: Semiconductor laser array device
Inventor: YAMAMOTO ATSUYA
IPC: H01S5/40
Filed: 1986-04-04
Abstract: PURPOSE:To facilitate monolithic integration by a method wherein a plurality of lasers which have double-hetero structure and stripe-shape current injection regions are formed and the widths of the respective stripes are different for the respective lasers. CONSTITUTION:A P-type buffer layer 7, a P-type AlGaAs cladding layer 6, an AlGaAs active layer 5, an N-type AlGaAs cladding layer 4, an N-type GaAs cap layer 3 and an AlGaAs isolation layer 2 are successively grown on a conductive P-type GaAl substrate 8. Then a stripe structure, whose which is different for every laser, is formed in the AlGaAs isolation layer 2 by chemi cal etching. If the width of the stripe is changed for every laser in the array, a threshold current density is changed. As a result, by the change of a Fermi level depending upon the injected carrier quantity, the respective lasers oscillate with wavelengths different from each other. Therefore, the extra process such as changing the oscillation wavelength by changing Al mixed crystal ratio becomes unnecessary.

Filed: 1986-04-05
Abstract: PURPOSE:To make possible high-load transmission with longevity and low noise by forming the pulley contact faces, at least, of the blocks out of hard resin material mixed with organically reinforced fiber and containing a friction- regulating drug. CONSTITUTION:A V-belt 1 is made up of pair of heavy-duty endless belts 2, 3 and V-blocks 4 is engagingly locked at a fixed pitch longitudinally. Each block 4 is formed on its side with an opening engagement groove, the upper and lower faces of which are formed with a projecting portion 6 in angle-shape in cross-section and a curved projecting face 7. Also, the pulley contact faces, at least, V-blocks 4 are formed out of high rigidity material using organic fiber, such as nylon, polyester, aramid, vinylon and the like. And as a friction- regulating drug to be contained in said material is used Teflon powder, which lowers statical friction coefficient between the pulley material and blocks 4 and does not lower dynamical friction coefficient much and does not harm transmission capacity and lowers noise. Accordingly, high-load transmission with longevity and low noise is possible.
