摘要： PROBLEM TO BE SOLVED: To provide a tunnel transistor having less gate leakage or gate capacity by eliminating a joint area between a gate layer and a source area as well as a joint area between the gate layer and a drain area. SOLUTION: In this tunnel transistor, a channel layer 2 is formed between a source area 5 and a drain area 6, and a gate layer 4 is formed on the channel layer 2 with an insulation layer 3 in between. The tunnel transistor is provided with the first conductivity type channel layer 2 formed on a substrate 1, the insulation layer 3 formed thereon, the gate layer 4 which has second conductivity type different from the first conductivity type and is made of a degenerated semiconductor and is formed on the insulation layer 3, the drain area 6 which is formed on the substrate 1 while being in contact with one side 2a of the channel layer 2 and is made of second conductivity type degenerated semiconductor, the source area 5 which is formed on the substrate 1 while being in contact with the other side 2b of the channel layer 2 and is made of second conductivity type degenerated semiconductor, and a source electrode 7, a gate electrode 8 and a drain electrode 9 which are formed respectively in the source area 5, gate layer 4 and drain area 6.

摘要： PROBLEM TO BE SOLVED: To provide a system that can accept a dispatching a taxi even though a requesting procedure to call the taxi company is unknown. SOLUTION: A disclosed taxi call system receives the calling for dispatching the taxi at a taxi call terminal 10 via Internet 1. A service station 3 connected to the Internet 1, then, recognizes a transmission position of a taxi call terminal 10 and sends the position data of the taxi call terminal 10 and the taxi dispatch data from the call terminal 10 to a taxi company terminal 4 or a taxi terminal 81, 82, and so on via the Internet 1. Therefore, a person who calls the taxi can get the taxi dispatch without knowing a telephone number of the taxi company. Consequently, the system can realize the taxi dispatch that satisfies customer requirements.
