摘要:
An optical absorption layer comprised of a substance having a band gap energy smaller than that of GaN is formed on an implanted region formed in a pGaN layer as a ground layer. There is performed an annealing step from an upper surface of a substrate with predetermined light such as infrared light, a red light, or the like, which has energy smaller than the band gap energy of the pGaN layer. The optical absorption layer has an absorption coefficient of the light in the annealing step larger than that of the pGaN layer. Accordingly, it is possible to selectively perform a heat treatment on a region directly under the optical absorption layer or a region in a vicinity thereof (the implanted region).

A fuel cell assembly has a housing defining an electricity generation/combustion chamber, and electricity generation/combustion means disposed within the housing. A fuel gas and an oxygen-containing gas are supplied to the electricity generation/combustion means, and a combustion gas formed within the electricity generation/combustion chamber is discharged from the electricity generation/combustion chamber. A heat exchanger having a first channel and a second channel is disposed on at least one surface of the housing, the combustion gas is discharged from the interior of the electricity generation/combustion chamber through the first channel of the heat exchanger, and one of the oxygen-containing gas and the fuel gas is supplied to the electricity generation/combustion means through the second channel of the heat exchanger. A plurality of electricity generation units are arranged in parallel within the housing, and each of the electricity generation units includes a cell stack constituting the electricity generation/combustion means.

A rotor for an open-end spinning machine. A spinning portion of a bottomed cylindrical body has a hollow portion where twisted yarn is formed by a continuous twisting operation while gathering short fiber groups in the maximum diameter portion of the spinning chamber. A rotary shaft is joined to the spinning portion. The spinning portion is made of a silicon nitride sintered body which includes no less than 60% silicon nitride grain having an aspect ratio not less than 3, and an average grain size of from 0.1 to 10 .mu.m. The rotor is hardly damaged at a high speed rotation of 100,000 r.p.m. or more, and the yarn strength and the yarn quality are not reduced even after an extended use of the rotor for a long time.
摘要:
A key telephone system includes a temporary registration memory for temporarily storing operating data and a final registration timing data memory for storing final registration timing data, including a timing condition for transferring contents of the temporary registration memory to the operating data memory. Operating data input by a user and the final registration timing data are written into the temporary registration memory and the final registration timing data memory, respectively, from a data input unit connected to the main unit during a data setting mode. The system discriminates establishment of the timing condition designated in accordance with the final registration timing data stored in the final registration timing data memory, whereupon the operating data stored in the temporary registration memory is transferred to the operating data memory.
