Title: Semiconductor laser
Inventor: NITTA ATSUSHI
IPC: H01S5/026
Filed: 1989-10-09
Abstract: PURPOSE:To enable laser oscillation at a wavelength corresponding to the low quantum level of a quantum well having the lowest band gap in a main active layer by injecting current into the active layer alone. CONSTITUTION:Light is emitted from first and second quantum wells 4a1 and 4a3 in a first active layer 4a and a third quantum well 4b1 in a second active layer 4b. The first and third quantum wells 4a1 and 4b1 have the same low quantum level (n=1). The light from these wells is absorbed in the second quantum well 4a3. This is because this light has a larger energy than that of the radiation developed in a transition between the low quantum levels of the second quantum well 4a3 since the first quantum well 4a1 has a greater band gap than the second quantum well 4a3. However, the absorption of light can be controlled by the current to be injected into quantum wells; that is, the absorption of light in the second well 4a3 is controlled by varying the current to the first active layer 4a through a first electrode 7a and a third electrode 8.

Title: Method for checking stack extension
Inventor: KUWABARA KEIJI
IPC: G06F11/00
Filed: 1988-10-20
Abstract: PURPOSE:To clearly distinguish the run away of a program from the shortage of a main memory and to improve reliability by providing a means to judge whether a page fault address is the same as the value of a stack pointer or not. CONSTITUTION:When a fault address A is smaller than a stack extension boundary B, it is regarded as invalid address access caused by the run away of the program, and when the fault address A is larger than the stack extension boundary B, the fault address A is subtracted from a leading address C of a stack, and capacity to be extended is obtained. Next, the existence of the free area of physical space 2 for the obtained capacity is checked, and when the free area equivalent to the number of pages for an extension request exists, the free area is secured. When no free area exists, the fault address A is compared with the value of a stack pointer SP, and while the fault address A is judged as an invalid address at the time of noncoincidence, a waiting state is kept until the free area is given to the main memory at the time of coincidence. Thus, the run away of the program and the shortage of the main memory can be clearly distinguished, and the reliability of the processing can be widely improved.
