Patent JP-H06268546-A (JP)
Title: Direct conversion receiver
Inventor: TSURUMI HIROSHI
IPC: H04B1/30
Filed: 1993-03-10
Abstract: PURPOSE:To reduce spurious radiation power in an output of a local oscillator from an antenna by setting output phases of the local oscillator inputted to a mixer so as to cancel each other. CONSTITUTION:An output signal from a local oscillator 31 is divided into 4 systems, which are inputted to mixers 23, 25, 27, 29. Then a signal leaked from the mixer 23 is leaked to an RF circuit while the phase is not shifted, then a signal leaked from the mixer 25 is shifted by pi/2 at a phase shifter 19, a signal leaked from the mixer 27 is shifted by pi at a phase shifter 17, and a signal leaked from the mixer 29 is shifted by 3pi/2 in total at phase shifters 21, 17. The phase shifters 17, 19, 21 are simply realized by extending the length of a microstrip line or a strip line by wavelengths corresponding to pi and pi/2. Thus, the leaked signals from the mixers are cancelled together and even when isolation is not complete, it is possible to eliminate a leakage signal from the antenna 11.

Abstract: PURPOSE:To provide an operation method whereby even when the amount of cut coke is constant in a dry quencher, the inventory level of coke in the quencher can be kept in a suitable range. CONSTITUTION:The amount of cut coke Wi per unit time is made constant, and the inventory level Li+n at the pushing completion time ti+n is determined by adding the amount of red-hot coke Ci fed from the coke oven to the inventory level Li at the pushing initiation time ti and subtracting Wi and the amount of cut coke calculated from the period from ti to tI+n from the resulting sum. When the determined inventory leveli+n is higher than the upper proper inventory level LH, LH is subtracted from Li+n to determine a surplus Li+n and this Li+n is divided by Wi to determine the time ti+n necessary for obtaining the amount of cut coke corresponding to Li+n. The pushing completion time ti+n is prolonged by ti+n.
