Abstract: PURPOSE:To prevent crosstalk of a transmission output to a receiver without use of a PIN diode switch with high dielectric strength by providing a circulator, a PIN diode switch and a detection circuit so as to utilize the isolation between terminals of the circulator. CONSTITUTION:The circuit is provided with a PIN diode switch 13, a circulator 14 and a detection circuit 16, an output of a transmitter 11 connects to a 1st terminal (a) of the circulator, an antenna 15 connects to a 2nd terminal (b) of the circulator and an input of the PIN diode switch 13 and the input of the detection circuit 16 connect to a 3rd terminal (c) of the circulator. The output of the PIN diode switch 13 connects to a receiver 12 and the output of the detection circuit 16 connects to the transmitter 11. The detection circuit 16 detects a level between the 3rd terminal (c) of the circulator 14 and the input of the PIN diode switch 13 and sends its output to the transmitter 11.

Title: Manufacture of plate for lead storage battery
Inventor: IKARI SHINICHI
IPC: H01M4/20
Filed: 1983-09-28
Abstract: PURPOSE:To simplify the manufacture of a plate for a lead storage battery by packing a lead oxide paste into a conductive core metal structure made of a lead alloy and then coating the surfaces of the thus formed body with mat sheets, followed by sticking a comb-like projection piece made of a thermoplastic synthetic resin into the thus formed body before the protruding ends of the comb-like piece are fused and fixed. CONSTITUTION:After a lead oxide paste 6 is packed into a conductive core metal structure made of a lead alloy and having a lug 1, metal cores 3 and lateral crosspieces 2 and 4, the surfaces of the thus formed body are coated with mat sheets 7. Then a comb-like projection piece made of a polystyrene resin or similar material and having projections 9 and connection belts 10 is stuck into the thus formed body from its one surface. After that, portions of the comb-like piece protruding from the other surface are fused and fixed to form fixed sections 11, thereby making a mat-like pasted plate consisting of a unified body of the mat sheets 7 and the paste 6. By the means mentioned above, the mass production efficiency of the plate can be increased by simplifying its manufacture. Furthermore, since no resin frames are used, it is possible to increase the capacity of a lead storage battery by increasing the amount of the paste 6 packed and the amount of electrolyte held in the battery.
