Title: Servo control circuit
Inventor: IMAI YASUAKI
IPC: G05D3/12
Filed: 1985-11-06
Abstract: PURPOSE:To attain accurate and stable control operation by providing a switch changing over an offset voltage of a subtraction circuit according to the operating mode to obtain an error signal corresponding to an error accurately. CONSTITUTION:A difference signal Vd obtained by adding an offset voltage Vdf to a difference signal Vd of a subtractor 13 and a sum signal Vs' obtained by adding an offset voltage signal Vsf to a sum signal Vs of an adder 14 are inputted to a divider 15. Then the divider 15 uses the corrected difference signal Vd' and the sum signal Vs' to output a focus error signal Ve. The offset voltage Vdf is a voltage Vdfw at the recording by the operation of an analog switch 21 and becomes a voltage Vdfr at the reproduction. Further, the offset voltage Vsf becomes a voltage Vsfw at the recording by the operation of an analog switch 22 and becomes a voltage Vsfr at the reproduction. The error of the difference signal Vd and sum signal Vs is corrected by using the correcting voltage to obtain a focus error signal Ve' equal to an error signal.

Title: Feedwater heater
Inventor: BABA TAKAO
IPC: F22D1/32
Filed: 1990-09-19
Abstract: PURPOSE:To substantially reduce the amount of radiation at a nuclear power plant and contribute to lessening of the exposure of workers at such a plant to radiation by providing a heater tube formed of a ferritic stainless steel and treated by electrolytic polishing. CONSTITUTION:A heater tube 23 is formed of a ferritic stainless steel SUS 434 and treated by electrolytic polishing. The corrosion rate of electropolished ferritic stainless steel SUS 434 is 0.05mg/cm<2>/20 days, the electrolytic polishing decreasing the amount of elution to about 1/10. This effect is considered to be due to smoothing of the surface and hence diminution of the surface area by the electropolishing treatment. With corrosion products generated in feedwater reduced to about 1/10 in quantity, the quantity of the radionuclide produced in the core of a reactor pressure vessel 1 also decreases considerably. At a nuclear power plant, a decrease in the amount of radiation results and it becomes possible to reduce the amount of the radiation to which the workers are exposed.

Filed: 1990-09-19
Abstract: PURPOSE:To enhance safety of a brake circuit by cutting the brake circuit in multiranges by means of plural contacts which belong to a different circuit. CONSTITUTION:A brake opening output buffer Z15B stops conducting electricity in response to a stop command, to demagnetize a brake opening contactor 15B. In this case, excitation of a magnet brake coil is continued when some trouble occurs at the contact 15B1 of the brake opening contactor 15B. When a running command is called off the output buffer A10T of a running contactor 10T stops conducting electricity so as to demagnetize the running contactor 10T. Braking is thus possible by demagnetization of the magnet brake coil using the contact 10T2 of th running contactor 10T. When some trouble occurs at the contact 10T2 of the running contactor 10T the contact 15B1 of the brake opening contactor 15B backs up the circuit in the same way.
