Title: Light emitting element
Inventor: KAMIJO TAKESHI
IPC: H01S5/00
Filed: 1985-05-27
Abstract: PURPOSE:To implement a direct transition type band structure, whose effective state density is high, and to obtain a semiconductor laser having high light emitting efficiency, by using a quantum well structure for an active layer, and using a mixed crystal semiconductor, which has a composition in the vicinity of the changing point between direct transition and indirect transition, for the material of the quantum well layer. CONSTITUTION:A semiconductor laser comprises a first conducting type, e.g., P-type AlGaAs clad layer 14, an AlGaAs quantum well active layer 15 and a second conducting type, e.g., N-type AlGaAs clad layer 16. The active layer 15 has a quantum well structure, in which AlyGa1-yAs barrier layers and AlzGa1-zAs well layers are repeatedly laminated. The composition of the AlzGa1-zAs is located in the vicinity of the changing point between a direct transition type and an indirect transition type. Therefore, the value of (z) is approx. 0.35-0.45. The composition of (y) of the barrier layer is set at, e.g., about 0.5-0.55. The composition of the clad layer is set at, e.g., about 0.7. In this structure, when, e.g., the composition is set at approx. z=0.4, the wavelength of oscillation is 600nm. Thus a semiconductor laser in the 600nm band can be obtained.

Title: Monitor method for process data by program loader
Inventor: NAGURA TAKU
IPC: G06F11/32
Filed: 1985-05-27
Abstract: PURPOSE:To monitor the transition of the process data without using a special measuring instrument by designating an area of a circuit where the control items are carried out and at the same time displaying the collected process data. CONSTITUTION:An area of a circuit where the control items are carried out is designated for a programmable controller PC. Thus the present values of the process data on said designated circuit area are collected. This collection data is sent to a display device 8 and a printer 10 within a program loader PL and then displayed and printed in the form of the transition of the process data. This operation is repeated for each prescribed period of time. Thus the transition of the process data is displayed on the device 8 in terms of time and also printed by the printer 10. In such a way, the transition of the process data can be monitored without using any special measuring instrument.

Title: Kana character correcting method
Inventor: TOBISAWA HIROE
IPC: G06F17/22
Filed: 1986-05-20
Abstract: PURPOSE:To attain correction of the 1st KANA (Japanese syllabary) character into the 2nd KANA character in terms of such characters that are easily mistaken just with a single operation of a correction key, by providing a table storing the conversion data for input of KANA characters to be converted into Roman characters. CONSTITUTION:The conversion data are previously stored in a conversion table by a user for conversion of the 1st KANA character which is easily mistake into the corrected 2nd KANA character. If the 1st KANA character is supplied via a key input function 18, the 1st KANA character set on a cursor is decided with push of a correction key and via deciding function 21 for characters set at cursor position. Then the 1st KANA character is converted into the 2nd KANA character to be corrected via the table 22. The corresponding character is shifted to a single character display function 24 with output 23 and a KANA character is displayed in a single character display area. Thus it is possible to correct such 1st KANA character into the 2nd KANA character just with a single operation of the correction key.
