Title: Circuit for detecting receiving timing and burst signal receiver
Inventor: KUBOTA MINORU
IPC: H04B1/16
Filed: 2001-08-30
Abstract: PROBLEM TO BE SOLVED: To provide a receiving timing detection circuit capable of transmitting a highly reliable receiving timing signal by solving the problem of being unable to receive an original receiving signal in the case a conventional interference signal is received erroneously. SOLUTION: A digitized RSSI (received signal strength indication) signal is delayed, and a sample value of an RSSI signal that temporally precedes is defined as a reference value to calculate an increasing amount of the RSSI signal. Next, the increasing amount is calculated by subtracting the reference value from the sample value of a subsequently inputted RSSI signal. Finally, in the case the obtained increasing amount surpasses a set increasing amount threshold, a detection signal is outputted, and a receiving timing signal is transmitted to an AGC (automatic gain controlled) circuit and a demodulation circuit.

Title: Connection part of aluminum-twisted conductor and terminal, and its connection method
Inventor: MIYOSHI TAKASHI
IPC: H01B13/00
Filed: 2001-09-06
Abstract: PROBLEM TO BE SOLVED: To provide a connection part of an aluminum-twisted conductor and a terminal, which is excellent in connection characteristic. SOLUTION: In the connection part of the twisted conductor 3, which is constituted with twisted Al wires, the above Al wire has a wire thickness of 1.0 mm or less, and the above Al wire and the terminal 4 are connected by a pressure jointing method while giving ultrasonic vibration through the terminal 4. Since the Al wires, which constitute the twisted conductor 3, are mutually gathered finely, by the ultrasonic vibration given at the time of the pressure jointing, invasion of corrosive gas into the twisted conductor 3 is prevented, and by this, oxidization and corrosion on the surface of the wires are prevented, and the wires contact good mutually. Moreover, since the ultrasonic vibration is given through the terminal 4, the wire-cut cannot occur easily. Therefore, the twisted conductor 3 and a terminal 4 are connected well.  Furthermore, since the wires are thin, the twisted conductor 3 is excellent in flexibility too. Therefor, making the constitution of the cables for cars with Al, that is, making car lightweight, is realized.
