摘要:
In a group III nitride compound semiconductor light-emitting device, a light-emitting layer having a portion where an InGaN layer is interposed between AlGaN layers on both sides thereof is employed. By controlling the thickness, growth rate and growth temperature of InGaN layer which is a well layer and the thickness of AlGaN layer which is a barrier layer so that they are optimized, the output of the light-emitting device is enhanced.

There is provided a switch device in a communication system in which a relay service of a cell or packet is provided on demand. A layer-3 communication controller performs a signaling control of a call set-up/release requested by a user terminal in accordance with a layer-3 communication protocol. A layer-3 communication restart controller can be connected to the user terminal in accordance with the layer-3 communication protocol and is connected to controllers in the switch device via a given interface. The layer-3 communication restart controller requests a call release process for a call managed by the layer-3 communication controller in accordance with a restart request for a call from the user terminal, and requests a restart process to the user terminal in accordance with a call release process issued in the switch device.

A layer comprising cobalt (Co) is formed on a p+ layer by vapor deposition, and layer comprising gold (Au) is formed thereon. The two layers are alloyed by a heat treatment to form a light-transmitting electrode. The light-transmitting electrode therefore has reduced contact resistance and improved light transmission properties, and gives a light-emitting patten which is stable over a long time. Furthermore, since cobalt (Co) is an element having a large work function, satisfactory ohmic properties are obtained.

A system for processing information with an electronic pen includes a coordinates indicating device and a coordinates sensing device. Both of the devices serves to output the information stored in itself to each other and store the information outputted from the other. The power supply for driving the information processing system itself is fed by a battery built in the coordinates indicating device.
