摘要:
To improve user-friendliness, icons selectable by a user are automatically generated by synthesizing more basic graphics. The system for displaying icons according to utilization frequency and to comprehensively express the computer's various modes. An icon pattern memory stores a plurality of graphic elements representing icon patterns which can be combined to generate the icons used in the computer. An icon pattern synthesizer synthesizing icon patterns in the icon pattern memory to generate the icons. An icon utilization controller controls the icon synthesis by the icon pattern synthesizer according to the user's input and monitors the utilization of all icons that can be synthesized by the icon synthesizer. A display controller controls display of a plurality of icons on the display screen of the computer according to the icon utilization, under the control of the icon utilization controller.
摘要:
A light emitting semiconductor diode comprises a first semiconductor region having a first conductivity type and a narrow forbidden band gap, a second semiconductor region, disposed on the first semiconductor region, having the first conductivity type and a low impurity concentration, a third semiconductor region, disposed on the second semiconductor region, having a second conductivity type which is opposite to the first conductivity type, and an ohmic contact disposed on the surface of the first semiconductor region, which is opposite to the second semiconductor region. The surface has a plurality of holes extending from the outer surface through the first semiconductor region toward a p-n junction between the second and third semiconductor regions, which holes are filled with a highly reflective metal having a high thermal conductivity.
摘要:
In an epitaxial growth method in liquid phase for III-V compound semiconductor crystals a solution for crystal growth is at first heated to a temperature which is higher than the temperature of crystal growth, and then cooled to that temperature, whereby a part of the solution crystallizes out as small crystals. This solution is separated by means of a filter means into two parts, one of which contains the small crystals and the other of which does not. A substrate crystal is brought into contact with the latter.
