Title: Semiconductor laser element
Inventor: FUJIWARA KENZOU
IPC: H01S5/22
Filed: 1983-07-26
Abstract: PURPOSE:To contrive to improve the crystal quality in an active layer by a method wherein a stepped multiplex hetero junction structure having a crystal lattice mismatching inductive strain is inserted in between a GaAs substrate and the active layer. CONSTITUTION:A stepped multiplex hetero junction layer 11 is provided in between a GaAs substrate 1 and an active layer 10. At this time, the thickness (h) of each AlxGa1-xAs mixed crystal epitaxial layer and the lattice mismatching degree in the layer 11 must sstisfy a condition that the thickness (h) is smaller than the critical value, at which a crystal lattice mismatching inductive transition is caused. In an AlxGa1-xAs system-short wavelength semiconductor laser element having the layer 11 with such a constitution, large lattice mismatchings existing between the substrate 1 and AlxGa1-xAs mixed crystal layers in an active layer 3 and clad layers 2 and 4 can be relaxed and dissolved in stages by the lattice mismatching inductive strain in each mixed crystal layer hetero junction set in a stair form, thereby enabling to prevent the generation and propagation of crystal defect such as a dislocation, etc.

And a rewinding control circuit 202 is actuated to rotate a motor 30. When a gear 31 is rotated clockwise by the motor 30, the locking pawl 4 starts to move right upward and the rear cover 1 is closed because the pawl 1a is pulled by the locking pawl 4. Thus, the locking means is integrated with the lock releasing means so as to be used as the automatic rear cover closing means and since the means for locking the rear cover 1 is not directly linked with the motor 30, there is not possibility of harming the motor 30 even if the excessive external force is given to the rear cover 1 in the half-opening state of the rear cover.

IPC: H04B10/07
Filed: 1989-06-02
Abstract: PURPOSE:To remarkably relax the request condition to a semiconductor laser and to reduce the cost by providing a converting part to low frequency, an electro/optical conversion transmitting part, an onto/electric conversion receiving part and a converting part to a high frequency band. CONSTITUTION:An electric signal of a high frequency band inputted to a terminal 1 is converted to a signal of a low frequency band by a frequency converting part 6, and inputted to an electro/optical conversion transmitting part 2 by a semiconductor laser. An optical signal of the transmitting part is transmitted to an opto/electric conversion receiving part 4 through an optical fiber 3 and converted into a high frequency band by a frequency converting part 7, and outputted from a terminal 5.
