Title: Semiconductor laser element
Inventor: TANAKA TOSHIAKI
IPC: H01S5/00
Filed: 1994-12-21
Abstract: PURPOSE: To improve the efficiency of carrier injection to a light emitting active layer, and realize a highly efficient laser operation at a low threshold value, by restraining the carrier which transfers from the direct transition Γband structure to the indirect transition X band structure. CONSTITUTION: The carrier which causes the band filling effect making electron density of a conduction band in a light emitting active layer excessive and transfers from the direct transition Γ band structure to the indirect X band structure is restrained. By the carrier restraint, the band structure wherein the carrier is confined in the direct transition Γ band structure is formed. The transition provability of light emission from the direct transition Γ band structure is increased and laser operation is realized. Even in the case where the direct transition band structure is adjacent to the indirect transition band structure, the carrier injection efficiency is improved and the luminous efficiency can be increased, by improving the the carrier density stored in the direct transition band structure.

Title: Multiplier
Inventor: UEDA TAKASHI
IPC: G06F7/52
Filed: 1994-12-21
Abstract: PURPOSE: To provide a multiplier which can shorten its calculation time without shortening the cycle of an external clock signal CLK. CONSTITUTION: An external clock signal CLK is conventionally used to an output feedback type multiplier. However, an internal clock signal ICLK having a shorter cycle than the signal CLK is produced and used to the multiplier. The signal ICLK is generated synchronously with the signal CLK and therefore no problem is caused in transfer of a multiplicand X, a multiplier Y or the multiplication result Z. The cycle of the signal ICLK is short and therefore the calculation time of the multiplier is also shortened.
