IPC: G21F9/06
Filed: 1983-10-06
Abstract: PURPOSE:To remove volatile impurities in liquid metal quickly and to regenerate the metal by providing a cylindrical body having a bottom plate perforated with many small dripping holes to the convex part of a vessel having free liquid surface and passing liquid metal through the cylindrical body. CONSTITUTION:Plural brackets 18 are fixed to the convex internal peripheral surface of a vessel having free liquid surface 9' toward the center of the vessel with equi-angular distance. A cylindrical body 21 having a bottom plate 19 perforated with many small dripping holes 20 are fixed by supporting on the bracket 18 concentrically with the vessel 9'. Liquid metal 17 contg. volatile impurities is intoduced from an introducing pipe 7a in a circulation line into the cylindrical body 21 and is discharged from a discharging pipe 7b. Thus, the volatile impurities are discharged from the discharging line 13 by forming gas on the surface of the liquid metal, moreover, the volatile impurities are vaporized and discharged by dripping the liquid metal from small holes 20 on the bottom plate 19.

Title: Infrared sensor
Inventor: SAKATA MASAKAZU
IPC: G01J1/04
Filed: 1989-07-19
Abstract: PURPOSE:To obtain high output power stably and to obtain excellent response by providing a pulse-shaped waveform wherein a positive voltage, a zero voltage, a negative voltage and the zero voltage are repeated at a specified period which is associated with the sensitivity of a detecting body for a driving voltage of a liquid crystal chopper. CONSTITUTION:Infrared rays 3 which are emitted from a material to be measured 2 are intermittently conducted and cut with a liquid crystal chopper 4. The infrared rays are intermittently projected on a detecting body 1. The amount of the projected infrared rays and the temperature of the material to be measured 2 are computed with a control part 6. The results are imparted into a display part 7 and displayed. A positive voltage, a zero voltage, a negative voltage and the positive voltage are sequentially imparted to the chopper 4 from a driving circuit 8. The large difference is obtained between the infrared-ray transmittance when the infrared rays are transmitted and the infrared-ray transmittance at the time of cut-off. The difference in transmittances in the chopper 4 is increased in response to the increase in period within a range wherein the period of the driving voltage is within one second. However, the peak of the output values is present at a part where the period is about 0.6 - 0.7 second. Namely, the high output power can be obtained by determining the period of the driving voltage of the chopper 4 in association with the sensitivity of the detecting body 1.
