IPC: C09K11/08
Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To produce a phosphor of Ga1-x Inx N:A (0<=x<0.8; A=Zn, Mg or Cd) in high quality. SOLUTION: Ga2 O3 (93.6g) and ZnS (0.1g) are mixed and fired in the air at 1,200 deg.C for 2 hours to prepare Zn-containig Ga2 O3 . Ar gas and NH3 gas are introduced into the heat treatment apparatus, and high-temperature plasma is generated by means of the RF coil. Powdery Ga2 O3 is introduced into the apparatus and nitrided by passing through the plasma to form almost spherical phosphor. This phosphor is applied to the anode of a fluorescent display tube to compare its brightness with that of conventional phosphor. The brightness of this phosphor is 150, when the one of the conventional product is regarded as to be 100. In continuous lighting, the deterioration of brightness is hardly recognized even after passage of about 2,000 hours.

Title: Barrel shifter
Inventor: NAKAHARA MAKOTO
IPC: G06F7/76
Filed: 1991-03-15
Abstract: PURPOSE:To output a processing result at a high speed by selecting and outputting one output from more than two outputs among the outputs of plural shifters. CONSTITUTION:A multiplexer 7 as a first output selection means selects and outputs one output from more than two outputs among the outputs of the plural shifters (1-1) to (1-5). The multiplexer 7 selects one of the plural shifters (1-1) to (1-5) and inputs input data. At the time of obtaining a necessary shifting amount, it is unnecessary to permit all the shifters (1-1) to (1-5) to pass through them. Only the shifters of a necessary minimum, which are necessary for obtaining the shifting amount to be obtained, are selected by using the selection of input or output so as to cause them to passing through. Thus, the processing result can be outputted at a high speed since the unnecessary shifter is not required to pass through them.
