Abstract: PROBLEM TO BE SOLVED: To make compatible the low on-resistance and high-speed turn-off characteristics of a bipolar transistor, when the electrodes of the bipolar transistor and a unipolar transistor are made of one layer of a metallic film and the wiring for connecting the bipolar transistor and the unipolar transistor is made of the one layer of the metallic film, by connecting through a wire bonding between the equipotential points of the electrodes or the wiring of the bipolar transistor and the unipolar transistor. SOLUTION: On a wiring 21 for connecting an emitter electrode 10a of an npn transistor BT2 and a drain electrode 11a of a p-channel MOS transistor UT3, an emitter wire 22 is made to contact with the near point to the electrode 10a and is so contacted with the near point to the electrode 11a via a short- circuit wire 22 as to perform stitch bondings. As a result, the wiring resistance between the emitter electrode 10a of a final stage and an E terminal is reduced so as enable making the on-voltage of the npn transistor BT2 reducible. Also, since the wiring resistance ranging to drain electrodes 11, 11a of transistors UT2, UT3 for extracting the base currents of transistors BT1, BT2 are also reduced, the base currents of the transistors BT1, BT2 are extracted quickly.

Filed: 1992-10-15
Abstract: PURPOSE:To cover the area of a leisured traffic with the small number of base stations and to reduce facility burden by forming a macro-cell by using plural repeater stations when the transmission outputs of mobile stations are limited. CONSTITUTION:In a service area 1a, a town 1b of heavy traffic is composed of micro-cells, and a suburb 1c of a leisured traffic is composed of macro-cells using repeater stations 4a. The transmission output of a base station 2a is made equal to that of mobile stations, and the transmission output of a macro- cell base station 3a is enlarged rather than that of mobile stations. The transmission power of repeater stations 4a is set at the value of a certain level required for the base station 3a. The base station 3a detects the repeater station 4a, which most strongly receives radio waves from the mobile stations, and performs communication by an up line while utilizing that repeater station 4a. The mobile station receives the radio wave of the base station 3a by a down line. The base station 3a directly performs communication when the station itself most strongly receives radio waves from the mobile stations. Thus, the area of a leisured traffic is covered with the small number of base stations, and the facility burden is reduced.

Filed: 1995-11-21
Abstract: PROBLEM TO BE SOLVED: To speedily and surely extend a slave set to a desired master set by judging a master set to be registered when detected electric field intensity changes by a prescribed pattern, so as to execute slave set extending operation. SOLUTION: In order to extend the slave set to the master set, an extension mode is set by prescribed operation by the master and slave sets at the same time. At this time an RSSI detection circuit 6 detects the electric field intensity of the master set to be received and sends it to a control circuit 7. The control circuit 7 judges whether electric field intensity of the signal from the master set which is received at the time is a fixed value or changes by the prescribed pattern from this detecting result and when electric field intensity does not change, the circuit 7 judges that the master set is not one to be registered and links with another master set. When electric field intensity changes by the prescribed pattern, the circuit 7 judges it to be a master set to be registered and mutually exchange ID to execute slave set extension operation.  Thereby the slave set is speedily and surely extended.
