Inventor: HANZAWA HIROSHI
IPC: G03B27/62
Filed: 1987-06-11
Abstract: PURPOSE:To precisely judge the stain of an original holding member and to prevent the stain of field by detecting the density of the original holding member with an optical detection means and detecting the stain of the original holding member with a stain detecting means based on the level of the detection signal. CONSTITUTION:The optical detection means and the stain detecting means provided opposite to the original holding member are provided, and the optical detection means detects the density of the original holding member and the stain detecting means detects the stain of the original holding member based on the level of the detection signal. Namely, in the case of preliminary scanning, an original 1 and a pressure plate sheet 3 is illuminated when a scanner unit 4 moves back and forward and the reflected light enters one end parts of optical fibers 12-14. Another end parts of the optical fibers 12-14 are optically combined with light receiving elements 15-17 consisting of photodiodes, which generate output current corresponding to the alternation of the quantity of light beams from the optical fibers 12-14. Thus, the stain of the original holding member can be precisely judged and the stain of field, etc., can be removed.

Title: Semiconductor laser device
Inventor: ANAYAMA CHIKASHI
IPC: H01S5/223
Filed: 1990-06-05
Abstract: PURPOSE:To enhance efficiency and inhibit the generation of heat by inserting a transition layer, which forms a potential barrier with an active layer where the composition ratio of As and the composition layer of P are identical to the active layer, between at least one sided clad layer of the active layer. CONSTITUTION:A potential barrier, which encloses electrons and holes by the use of an n<+> transition layer 14 and a p<+> transition layer 18 with a GaInAsP active layer 16, is formed. A potential barrier is further formed of an n<+> AlGaInP clad layer 12 and a p<+>AlGaInP ciad layer 20 with a layer 14 and a layer 20. The composition ratios of As and P is not subjected to any change, which prevents the recoupling of non-light emitting performance. On the interface between the layer 14 and the layer 12, and the interface between the layer 18 and the layer 20, the composition ratio of As and the composition ratio of P change, which produces the recoupling of non-light emitting performance. When electrons are injected into this laser device, the concentration of electrons is lowered on the interface, which reduces the recoupling speed of electrons by the lowered value. It is, therefore, possible to reduce the recoupling current and enhance the efficiency of a semiconductor laser device.

Title: Printing head
Inventor: INOGUCHI HIDEHIKO
IPC: B41J2/28
Filed: 1987-06-12
Abstract: PURPOSE:To prevent a laser-welded part from being separated out of place or cracks from generating on an area near a laser-welded part of leaf spring by providing a stopper which restricts the rotation of the rear end of an armature. CONSTITUTION:When wire 7 contacts a printing medium, a stopper 11a is contacted by an armature 6 immediately after leaf spring 5 touches a side yoke 9 by rotation of the armature 6 centering around the vicinity of a junctioned part between the wire 7 and the armature 6 under the inertia effect of the armature 6. Under this constitution, the magnetic flux of a magnet 3 is canceled by energization of a coil 2, and a leaf spring 5 is separated from a base yoke 1 by the elastic force of the leaf spring 5, causing the wire 7 to move toward a printing medium and contact the latter for printing. When the wire 7 touches the printing medium, a separation force which works between the armature 6 and the leaf spring 5 decreases because the rotation of the rear end of the armature is restricted by a stopper 11b. Subsequently the possibilities of the laser-welded part being separated out of place or cracks generating near the laser-welded part of the leaf spring are reduced.
