摘要:
A light-emitting semiconductor device (10) consecutively has a sapphire substrate (1), an AlN buffer layer (2), a silicon (Si) doped GaN n.sup.+ -layer (3) of high carrier (n-type) concentration, a Si-doped (Al.sub.X2 Ga.sub.1-x2).sub.y2 In.sub.1-y2 N n.sup.+ -layer (4) of high carrier (n-type) concentration, a zinc (Zn) and Si-doped (Al.sub.x1 Ga.sub.1-x1).sub.y1 In.sub.1-y1 N emission layer (5), and a Mg-doped (Al.sub.x2 Ga.sub.1-x2).sub.y2 In.sub.1-y2 N p-layer (6). The AlN buffer layer (2) has a 500 .ANG. thickness. The GaN n.sup.+ -layer (3) is about 2.0 .mu.m thick and has a 2.times.10.sup.18 /cm.sup.3 electron concentration. The n.sup.+ -layer (4) is about 2.0 .mu.m thick and has a 2.times.10.sup.18 /cm.sup.3 electron concentration. The emission layer (5) is about 0.5 .mu.m thick. The p-layer 6 is about 1.0 .mu.m thick and has a 2.times.10.sup.17 /cm.sup.3 hole concentration. Nickel electrodes (7, 8) are connected to the p-layer (6) and n.sup.+ -layer (4), respectively. A groove (9) electrically insulates the electrodes (7, 8). Lead lines (21, 22) are connected with the electrodes (7, 8) by a wedge bonding method to desirably reduce the surface area of the electrodes on the light-emitting side of the device upon which the electrodes are situated to thereby increase light emission from the device.

摘要:
Roasted coffee beans, roasted beans or roasted cereals are extracted with a cyclic dextrin-containing liquid and/or this extract is dried to obtain an instant beverage. According to this process, valuable components of roasted coffee beans or the like are effectively extracted by the cyclic dextrin-containing liquid, and extracted soluble and aromatic components are effectively protected by the cyclic dextrin when the extract is dried to form an instant beverage. The obtained instant beverage such as instant coffee has excellent fragrance and flavor.

An information terminal device is provided that may use the input functionality of a touch panel to remove the restriction on the use thereof, for example, release the key lock. The information terminal device (1) is an information terminal device including a display (11) and a touch panel (12), including: a pattern storage memory (43) configured to store a release pattern that is to be entered into the touch panel (12) to remove the restriction on the use of the information terminal device, the release pattern being designated by a user as a graphic pattern; a comparison unit (44) configured to determine whether an entered pattern entered into the touch panel matches the release pattern; and a controller (34) configured to remove the restriction on the use of the information terminal device if the comparison unit (44) determines that the entered pattern matches the release pattern.
摘要:
A light-emitting diode of GaN compound semiconductor emits a blue light from a plane rather than dots for improved luminous intensity. This diode includes a first electrode associated with a high-carrier density n.sup.+ layer and a second electrode associated with a high-impurity density i.sub.H -layer. These electrodes are made up of a first Ni layer (110 .ANG. thick), a second Ni layer (1000 .ANG. thick), an Al layer (1500 .ANG. thick), a Ti layer (1000 .ANG. thick), and a third Ni layer (2500 .ANG. thick). The Ni layers of dual structure permit a buffer layer to be formed between them. This buffer layer prevents the Ni layer from peeling. The direct contact of the Ni layer with GaN lowers a drive voltage for light emission and increases luminous intensity.
