Abstract: PROBLEM TO BE SOLVED: To improve the manufacturing yield of a semiconductor light emitting device by increasing the uniformity of element characteristic of the illuminant by reducing the damage to an active layer by performing mass transportation until the side face of a clad layer becomes (111)-plane. SOLUTION: After an n-type InP buffer layer l2 is grown on an n-type InP (100)-plane oriented substrate 1 and an active area having an SCH structure in which a strained MQW active layer 20 is held between InGaAlAs light guide layers 21 and 22 is grown on the buffer layer 2, a p-type InAlAs electron overflow suppressing layer 19 is grown on the outside of the p-side SCH structure and a p-type InP clad layer 12 is successively grown. Then an SiO2 film 13 is formed in a stripe-like state along the direction of the <011> inverted mesa and the film 13 is successively etched toward the substrate 1 by side etching. Thereafter, the width of the active layer 20 is controlled by side etching the two light guide layers 21 and 22 and active layer 20 until the active layer 20 becomes possible to make oscillation in a basic lateral mode and to make mass transportation.

IPC: H04N13/00
Filed: 1985-03-07
Abstract: PURPOSE:To permit the viewer to view the same picture by his left and right eyes by providing a light polarizing plate by which the outputs of a hair of TV cameras are switched and displayed in a shorter time than the human after-image time and changing the polarization direction in synchronization with the period of switching. CONSTITUTION:An object 1 is photographed simultaneously by left and right TV cameras 2R, 2L and the outputs are synthesized by a picture synthesizing circuit 3 while being switched in a period shorter than the after-image time of the human eye and alternately displayed on a display device 4. A modulation control circuit 6 controls an electro optical modulator 5 by a control signal synchronizing with the switching period to change the direction of plarization against the incident light to the horizontal and vertical directions alternately. In such a manner, only the light incident on the modulator 5 having alternately horizontal and vetical polarization components can pass through it. Hence, when the viewer views with a polarizing spectacles 7, only output signals from the cameras 2R, 2L can be seen from respective polarization plates 7R. 7L on the right and left sides, these images being combined in the viewer's brain give a stereo effect.

Title: Lid open/close device
Inventor: YAMAGUCHI YOICHI
IPC: B65D43/16
Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To damp rotation of a lid by providing a contact member which can move relatively with an elastic member in directions where it comes close to/farther away from a support point of the elastic member and is biased by elastic force of the elastic member in contact with the member. SOLUTION: A lid 3 is integrally equipped with a pressed piece 3a comprising a protruding form. An end 3e of the piece 3a which is a far end in a longitudinal direction is brought into contact with an arm 5b of a return coil spring 5 provided on a body 2. This constitution causes the lid 3 to rotate in a direction of opening the lid by force applied by an open coil spring 4 when a lock member is unhooked from a lid closing position. Then an end 3e of the piece 3a of the lid 3 interlocking with the rotation moves toward an attaching portion 6 while sliding on the arm 5b of the return coil spring 5. Thus biasing force in the direction of opening the lid which increases with the rotation works, so that the lid 3 exhibits a rotation operation at a suppressed rotation speed.
