Abstract: PURPOSE:To simplify structure of a refining apparatus and to facilitate the maintenance, by charging liquid metal from upper part of the refining apparatus composed of outer and inner barrels, cooling said metal, then catching impurities to discharge said metal from lower part. CONSTITUTION:To the refining apparatus 1 composed of an outer barrel 2 having a heat insulating layer 6 and an inner barrel 3 having a packing material 25, a liquid Na 4 contg. impurities is charged. The liquid 4 flows into a passage 13 from an entrance 8 at upper part, impurities are pptd. by cooling due to a cooling coil 14, simultaneously sp. gr. thereof is raised. Thus, the liquid 4 descends to the passage 13 due to natural convection, and enters to the material 25 from a circulation hole 23. Impurities pptd. thereat are caught to purify the liquid 4, and it flows out from an exit 11 at lower part through a circulation hole 24 and a passage 22. Flow rate of Na is measured by an electromagnetic flow meter 31 and controlled by operating a flow rate controlling valve 26 from upper part.

Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To suppress enlargement of the diameter of an arc without heightening the mercury sealing pressure of a discharge lamp by installing a lighting main circuit comprising a switching means which is so constituted as to turn on a d.c. power source and energize a high-pressure discharge lamp by overlaying low electric current at the lowest discharge maintaining current level of the high pressure discharge lamp or higher on pulsed electric current. SOLUTION: A pulse-generating switching apparatus 8 stores information to obtain a prescribed waveform of lamp electric current and controls the switching operation of a lighting main circuit 2 by outputting the information to a control means 7. Based on the above-mentioned information, the lamp electric current to be supplied to a high-pressure discharge lamp 4 is obtained by overlaying low electric current at the lowest discharge maintaining electric current level of the high-pressure discharge lamp 4 or higher on pulsed electric current repeated at prescribed cycles.  Consequently, the electric current supplied to the high-pressure discharge lamp 4 is low in relation to the repeated electric current in sinusoidal waveform and the desired lamp electric power is sufficiently supplied by the pulsed electric current, so that the arc temperature is lowered and spread of the arc is suppressed due to the decrease of the temperature.

Title: Developing device
Inventor: HASHIZUME KYOHEI
IPC: G03G15/08
Filed: 1990-10-05
Abstract: PURPOSE:To remove the cause of a difference in measuring and to accurately adjust the concentration of a developer when the developer is exchanged by setting the regulating value of the concentration of the developer at a range where the output properties of a concentration sensor are excellent. CONSTITUTION:Set value memory 7a and 7b stores the top/bottom threshold values of the concentration set in advance in the range where the linearity of the permeability- to-output characteristics of the concentration sensor 17a is secured. A deciding part 8a decides whether the value of the toner concentration measured by the sensor 17a is within the ranges of the top/bottom threshold values read out from the memory 7a and 7b, or not, when the developer 10a of a housing part 11a is exchanged. When the measured toner concentration value is within the ranges of the threshold values, as the result of the decision of the deciding part 8a, regulating value memory 190a stores the measured concentration value as a regulating value. When the measured toner concentration is out of the ranges of the top/bottom threshold values, as the result of the decision of the deciding means 8a, an error display part 21 carries out an error display. Thus, the concentration is accurately adjusted by the set regulating value, and when the measured value is out of the ranges of the top/bottom threshold values attaching precision is enhanced and the difference in the measuring is prevented.
