Title: Coherent side lobe canceller
Inventor: MIZUTANI AKIYOSHI
IPC: G01S7/02
Filed: 1990-09-17
Abstract: PURPOSE:To prevent influence even if level of an auxiliary system input interference wave is large by preventing signal from the auxiliary system from being given to a vector multiplication circuit according to a zero-level output of a first switch by providing a second switch. CONSTITUTION:When a CLSC (coherent side lobe canceller) ON/OFF signal is turned off, a first switch 6 is set to a zero-level side and at the same time a second switch 61 is also set to the zero-level side. Thus, control signal fed to a vector multiplication circuit 5 is set to a zero level, input to a circuit 5 of SLC (side lobe canceller) signal is prevented, and a zero-level signal is supplied instead. Therefore, even if isolation of the circuit 5 is not sufficient, it is guaranteed that output of the circuit 5 becomes 0 regardless of the level of the SLC signal. Thus, it is guaranteed that a main signal is not disturbed by a subtractor 1.

Title: Controlling method for special component flow rate
Inventor: TASAKA YASUO
IPC: F25J3/04
Filed: 1990-09-19
Abstract: PURPOSE:To stabilize operation of a crude argon tower and to eliminate a facility of catalyst tank temperature control by detecting oxygen concentration in crude argon by an oxygen concentration detector, calculating the flow rate of the crude argon to become a preset oxygen amount by a calculator, and regulating the flow rate by a crude argon flow rate regulating meter to become the flow rate of a calculated value. CONSTITUTION:Oxygen concentration in crude argon is detected by an oxygen concentration detector 12, introduced to a calculator 27, and the amount of the crude argon is calculated by the calculator 27 to become preset oxygen amount. The calculated value is outputted as a set value of a crude argon flow rate regulating meter 23. If the oxygen concentration in the argon is raised, the extracting flow rate of the argon is reduced to operate in a direction for reducing the oxygen concentration in the argon. On the contrary, if the oxygen concentration in the argon is reduced, the extracting flow rate of the argon is increased to operate in a direction for increasing the oxygen concentration in the argon. The flow rate of the argon is so set that the absolute amount of the oxygen in the argon becomes predetermined to always stably operate.

Title: Detecting apparatus of radiant heat
Inventor: YAJIMA RYUZABURO
IPC: F24F11/02
Filed: 1989-09-22
Abstract: PURPOSE:To prevent deterioration of the detecting accuracy by providing an operating means for calculating quantities of radiant heat based on the heat generating amount of a heat generating means and a temperature signal of a radiation sensor upon receipt of outputs of a heat generating amount controlling means and the radiation sensor. CONSTITUTION:A controller 5 controls the heat generating amount q0 of a thermoelectric element 2A so that a sensor temperature Ts detected by a surface temperature sensor 1 becomes equal to a peripheral air temperature Ta detected by an air temperature sensor 3. A wall temperature or a floor temperature Tr is obtained based on the sensor temperature Ts detected by the sensor 1 and heat generating amount q0 by an operating device 7. A warm heat or cool heat is added to the sensor 1 at this time so that the temperature Ts becomes equal to the temperature Ta, and therefore, a radiant heat qa from the air therearound to the sensor 1 is replaced with a supplied heat q0 of the element 2A. Accordingly, the temperature Tr can be detected from the amount of heat q0 and temperature signal of the sensor 1 without consideration taken into the conductivity of the thermal convection of the wind. As a result, the detecting accuracy of the radiant heat is prevented from being deteriorated by influences of the wind velocity.
