Title: Switch-able compensation for improved operation of oscillator
Inventor: TEIMOSHII DEII DEIBUISU
IPC: H03B5/32
Filed: 1993-10-15
Abstract: PURPOSE: To provide an oscillation circuit which can intrinsically operate stably and does not consume much electric power. CONSTITUTION: A low-power crystal oscillation circuit incorporating an amplifier section 12 having a switchable compensation network 14. In one example, the oscillation circuit incorporates inverting amplifiers 30-32 and generates a square wave output signal which is usable as a clock signal that drives, for example, a microprocessor or other digital circuits. Such knowledge that compensation is only required at the rise time for making the oscillation at a desired crystal frequency when an uncompensated band width is not excessively wide is utilized. Once desired oscillation is attained, most of oscillation cycles occur among the nonlinear areas of the amplifiers 30-32. Since these nonlinear areas are characterized by low gains, any types of spurious oscillation can be suppressed.  After the oscillation circuit rises, the power consumption of the circuit is saved by removing the compensation network 14.

IPC: G21C9/00
Filed: 1990-09-28
Abstract: PURPOSE:To cool a meltdown are and to prevent the excessive increase of the pressure and temperature of a containment vessel by burying a connection channel to which storage water in the bottom concrete of a lower dry well room is allowed to flow. CONSTITUTION:A reactor containment vessel 2 is divided into an upper dry well room 4, a lower dry well room 5 and a pressure control room 6. Particularly, in the bottom concrete of the lower dry well room, a connection channel 8 in which storage water 8 stored in the pressure control room 6 passes is buried. Accordingly, even if a severe accident accompanied by core damage should occur, a meltdown core damages the bottom part of a reactor pressure vessel 1 and, in the case where it falls on the bottom concrete of the lower dry well room 5, the meltdown core is cooled since storage water 7 stored in the pressure control room 6 is allowed to flow in the lower dry well room 5 through a connection channel 8. Thereby the excessive increase of the pressure and temperature in the containment vessel can be prevented.

Abstract: PROBLEM TO BE SOLVED: To reduce functional deterioration of a main lip by providing a first seal member having an outer peripheral seal part and the main lip and a second seal member having a sub-lip, and decreasing strain force to an axial surface of the main lip. SOLUTION: A first seal member 2 has an outer peripheral seal part 22, main lip 24 coming into slide contact with an axial surface to seal a fluid, a dust lip 25 for preventing infiltration of dust from an atmospheric side A, and forms a screw part 24a having a pump function toward a seal fluid side O in a surface of the atmospheric side A of the main lip 24. Strain force is imparted to the main lip 24 by a spring 26. A second seal member 3 has a sub-lip 34 coming into slide contact with the axial surface to prevent infiltration of foreign matter or the like. A pressure in a seal space 4 is increased by a pump effect, to provide possibility of foreign matter infiltrating in the seal space 4 by separating the sub-lip 34 from the axial surface. Therefore, strain force to a shaft of the main lip 24 is set low, and its durability can be improved by reducing wearing of the main lip 24 and the shaft.

Abstract: PURPOSE:To improve the code error ratio of a transmission earth station by providing a transmitter with a variable attenuator, an amplifier, an AGC circuit, and a means for deciding the existence of a transmission signal, and when there is no transmission signal, maximizing the attenuation value of the variable attenuator. CONSTITUTION:The transmitter is provided with the variable attenuator 9, the amplifier 12, the AGC circuit for feeding back a distribution signal outputted from the amplifier to the variable attenuator 9, a detector 10 to be a means for deciding the existence of a transmission signal, a comparator 18, and a transistor(TR) 20. Since the output voltage of a 1st detector 10 goes to 0V at the time of OFF of an input transmission signal, the output of the TR 20 goes to 'H' at the time of 'H' of an output from the comparator 18 and the control voltage of the variable attenuator 9 is positively increased independently of the output of an AGC amplifier 15, the attenuation variable is maximized and noise discharged from the transmitter is reduced. Consequently, interference to a signal wave generated from the transmission earth station can be reduced and the code error ratio of transmission data can be improved.
