Filed: 1989-01-23
Abstract: PURPOSE:To execute the arithmetic processing of data excepting numerical data without improving an A/P program by calling processing to input data, which is not permitted, through an intrinsic function. CONSTITUTION:In the calling of an intrinsic function call part 1a, when the data excepting a real number (input data not to be permitted by the function) are given, in an intrinsic function definition part 1b, the error call of input data illegality is executed by an error call definition part 1b-2. Then, processing to be designated by a location 1c-2 for an error call is executed according to an error class 1c-1 designated by an error call table 1c. Here, since the location of a processing part is defined to the location 1c-2 when the data excepting the real number are inputted, the expected processing can be executed. Thus, without newly preparing the function of the A/P program, the arithmetic of the data excepting the numerical data is executed by using the arithmetic operation intrinsic function integrated into a system.

Title: Semiconductor quantum well device
Inventor: YOSHIDA ICHIRO
IPC: H01S5/00
Filed: 1991-02-05
Abstract: PURPOSE:To provide a semiconductor quantum well device which can control carrier distribution inside a quantum well. CONSTITUTION:A plurality of thin layers 6 are inserted in a quantum well layer 2 of this semiconductor quantum well device. Since a second quantum well is further formed in the quantum well by the existence of the thin layer 6, the distribution of carrier in the quantum well is affected by density, width and band gap of the second quantum well. Therefore, carrier distribution in the quantum well can be controlled by adjusting the elements. Carrier distribution can be controlled to reduce an amount of carrier which effuses to a barrier 3 by making the existence density high in a central part of the quantum well layer 1 and low in an end part by using a groove layer whose band gap is smaller than that of a quantum well layer as illustrated.
