Title: High-temperature non-cooling diode laser
Inventor: RAJIYARAMU BAATO
IPC: H01S5/343
Filed: 1994-10-12
Abstract: PURPOSE: To operate a diode laser in a wide temperature range by providing an active layer that is made of a quantum well, giving a compression distortion of GalnAs compound arranged between a III-V semiconductor compound of an opposite conduction type and upper/lower cladding layers and a barrier layer made of AlGaInAs. CONSTITUTION: A transition layer 52 is stepped linearly in a composition between In0.48Al0.52As composition of layers 48 and 50 and the composition of a quantum-well barrier 56. Five quantum walls 54, sandwiching four barrier layers 56, are not doped and are subjected to compression distortion by Al0.18Ga0.22In0.70As composition. Four barrier layers 56 are made of Alx-Gay-Ini-x-yAs composition and gives a pull distortion for eliminating the compression distortion of the quantum well layer 54 with a band-gap of 1.0 μm. With this kind of structure, a laser for emitting 1.3 μm light can be obtained effectively, even at a high operating temperature.

Filed: 1989-10-19
Abstract: PURPOSE:To improve ease of observance of a decoded picture by providing an in-area information compression means compressing a feature extracted by an area extraction means and compressing split information of an partial area of an input picture and the feature in the local area separately. CONSTITUTION:A picture input section 211 converts a picture into a digital data and fetches the result. An area split section 211 divides the inputted picture into a local area whose feature is nearly uniform such as an area whose density is nearly uniform. The area division section 221 combines small areas with high similarity sequentially to form local areas and outputs the result of final area split to an area split information compression section 231, an area extraction section 241 and an in-area information compression section 251 as the area division information respectively, then to the area division information compression section 231, the result in matching with an average density in each area is outputted. The area division information compression section 231 extracts a contour line of the area based on the result of division obtained by the area division section 221 and compresses the result.

Title: Microcomputer
Inventor: SAGI KATSUICHI
IPC: G06F13/42
Filed: 1996-10-15
Abstract: PROBLEM TO BE SOLVED: To make a chip highly integrated by decreasing control signal wires of a microcomputer which has a peripheral circuit inside. SOLUTION: The CPU 1 and the peripheral circuit 7 are connected by such buses AD0 to AD15 that the number of the bits of data buses is larger than the number of the bits of address buses and where addresses and data are multiplexed, and data are written to the peripheral circuit and read out of it according to address signals outputted from the CPU 1 to the buses. While the CPU 1 outputs the addresses to the buses AD0 to AD9, a control signal is outputted as the address to a bus AD15 which is not used and this control signal is latched by a latch 8. While the data are outputted to the buses AD0 to AD15, specific operation for reading and writing the date is performed according to the control signal held by the latch 8. The need for a wire dedicated to the control signal is eliminated to decrease wires, thereby high integrating the chip.
