Title: Light emitting diode element and manufacture thereof
Inventor: TAKAMIZAWA YUJI
IPC: H01L33/14
Filed: 1989-06-14
Abstract: PURPOSE:To acquire a light emitting diode element of high output which can reduce a forward voltage by constituting a confinement layer of first conductivity type by a variation preventing layer consisting of first conductivity of low impurity concentration and a base layer consisting of first conductivity type of high impurity concentration. CONSTITUTION:A p-type confinement layer 2, an active layer 3, an n-type confinement layer 4, an n-type cap layer 5 and a multilayer growth layer are formed on a main side of an undoped GaAlAs substrate 1 through epitaxial growth. The p-type confinement layer 2 is composed of a thick base layer 21 consisting of a p-type GaAlAs of high impurity concentration and a thin variation preventing layer 22 which overlaps the base layer 2 and whose impurity concentration is low and the same as that of an active layer 3. Accordingly, a resistivity reduces, the base layer 21 becomes thick, and an electric resistance thereby becomes small and a forward voltage lowers due to an increase of an area of a current passing region and a reduction of resistivity. High output can be realized and a forward voltage becomes small in this way.

Title: Level compensation device for measuring device
Inventor: IWAFUNE SATOO
IPC: G01D11/06
Filed: 1979-11-20
Abstract: PURPOSE: To miniaturize a level compensation device by combining constraining members which constrain the back and forth movement of 2 pairs of hanging strings for an optical element for level compensation through the touching of said string at the intermediate position of the strings.  
     CONSTITUTION: An optical element for level compensation is hung by 2 pairs of hanging strings, and each pair of hanging strings are converged almost at a single point of the lower end. The upper ends of said hanging strings are mounted on the body part of a measuring device at an interval in a back and forth direction. In addition, constraining members 5 consisting of almost L shaped plate members are inserted between the pairs of hanging strings 2 and contact the inner side of hanging strings near the lower ends of the latter. Thus the constraining members constrain the back and forth movement of the hanging strings 2. Consequently, the leaning movement of the optical element 1 in a back and forth direction is subjected to the same action as when said element is suspended by a right and a left hanging string, that is, four pieces of the hanging strings work against a twist to block a twisting oscillation. Under this constitution, it is possible to prevent the twisting oscillation of the optical element without taking a wide horizontal space for the hanging strings, and miniaturize the level compensation device.
