Title: Control system
Inventor: AOKI KENICHI
IPC: H03F1/32
Filed: 1992-12-02
Abstract: PURPOSE:To eliminate distortion without a time lag and immune to the effect of external noise by predicting a level of distortion and its frequency in advance and applying a signal of an opposite phase to an original signal. CONSTITUTION:A frequency of a part of a signal received at an electric input terminal 10 is doubled by a frequency variable means 13 and the phase of the signal is inverted by a phase variable means 14. The frequency of the other part of the signal is trebled and the phase of the signal is inverted at other set of a frequency variable means 13 and a phase variable means 14. The signal whose frequency is doubled is controlled to have a voltage of -40dB being a level of second harmonic distortion and the signal whose frequency is trebled is controlled to have a voltage of -60dB being a level of third harmonic distortion by a control means 15 and the results are added to an original electric signal at an adder means 16. In this case, an arithmetic operation means 11 calculates a voltage frequency characteristic of the input signal to change a control variable for the control means 15. Since an input used to cancel 2nd and 3rd harmonic distortion is received by an electroacoustic transducer 17, the elimination of harmonic distortion is realized.

Abstract: PURPOSE:To cool reactor container without passing a cooling duct through a reactor container by connecting a cooling system to an annulus portion formed between a reactor vessel support wall and a reactor vessel support structure. CONSTITUTION:The load of a reactor vessel 1 is dispersed to a reactor vessel support wall 2 and a reactor vessel support structure 11 and transferred to a base mat 3, the structure 11 being secured to the mat 3 via a load support 15. Heat generated from the vessel 1 is removed by cooling, by means of a cooling system 6, an atmosphere in an annulus portion 13 formed between the vessel 1 and the structure 11; i.e., because the end of a reactor containment cooling duct 10 is open to the annulus portion 13, the atmosphere in the annulus portion 13 is forced to circulate by a reactor containment cooling blower 8 and is cooled by a reactor containment cooler 7 provided at part of the duct 10. The heat from the vessel 1 is thus removed outside the vessel, so the reactor container can be cooled without passing the end member of the duct 10 through the vessel.

Filed: 1993-12-22
Abstract: PURPOSE:To save control signal wiring for protection by respectively providing a circuit detecting an excess current and interrupting the current in a power source supply circuit for every chip on a wafer during burn-in. CONSTITUTION:The current Ic1 is supplied to respective chips of e.g. a DRAM on the wafer through FETs QN1, QP1. A power-on signal PHION is made an 'H', and then, power source Vcc is applied. A charging current to a capacitor C1 flows by about 30mA temporarily. Thereafter, the power-on signal PHION is made an 'L'. When the /RAS, /CAS terminals of the DRAM are made the 'L' an activated operation current Ic1 flows by about 30mA. If a defect chip exists, the current becomes 20OmA extent, and an output signal PHIOUT, is lowered e.g. by 1V by a voltage drop of a resistor R. The matter is detected by a NOR circuit constituted of the FETs QP2,3, QN2,3, and the FETs QN1 QP1 are turned 'OFF'. That is, no power source open/close signal wiring is laid separately for every chip.
