Title: Phased array antenna
Inventor: KAWAI MAKOTO
IPC: H01Q3/20
Filed: 1983-05-31
Abstract: PURPOSE:To attain the separate reception of plural signals with a small number of phase shifters regardless of the number of signals which are received at a time, by providing a waveform memory for each array element. CONSTITUTION:For a waveform memory 5, a switch 81 works so that the input and the output are connected to registers 91 and 92 respectively when the register 91 is used for the writing purpose. While a switch 82 works so that the signal writing and reading clocks are supplied to registers 91 and 92 respectively. Such states are switched for every fixed time 2T. As a result, the input signal S1+S2 of time width 2T is repeated twice with the time width reduced down to T. Therefore the phase shift amount of a phase shifter 3 is set at an amount corresponding to the signal S1 for the first time T and at an amount corresponding to the signal S2 for the next time T respectively. Thus it is possible to separate signals S1 and S2 from each other on a time axis in terms of an output signal.

Title: Manufacture of organic electrolyte cell
Inventor: NAKAI MASAKI
IPC: H01M4/06
Filed: 1987-04-17
Abstract: PURPOSE:To increase discharge capacity so as to stabilize internal resistance and battery size by heating a positive compact to a specific low temperature, and then heating to a specific high temperature. CONSTITUTION:A positive compact 4 is heated to a relatively low temperature in the range 80-180 deg.C, removing partially adhered or bound water and melting the binder to a small extent to confer slight adhesive properties. The compact is then heated to a high temperature in the range 200-300 deg.C to completely eliminate remaining water, completely melt the binder and strengthen its adhesion. As the expansion of the compact 4 due to heating is small, the cell can be provided with a larger compact 4 in advance and its capacity can therefore be increased. Further, as water is completely eliminated from the compact, increase of internal resistance or cell expansion can be prevented.
