  • Patent number: 10629414
    Abstract: A target supply device may be provided with a tank configured to contain a metal as a target material, a nozzle having a nozzle hole through which the target material is output from the tank, a filter disposed in a communication portion for conducting the target material from the tank to the nozzle hole, a temperature adjuster configured to change the temperature of the target material in the tank, and a controller controlling the temperature adjuster to change the temperature of the target material in the tank such that oxygen in the target material is precipitated as metal oxide.
    Type: Grant

  • Publication number: 20130000384
    Abstract: Gas pressure in a cavity is detected with a rod-shaped casing that attaches to an hole that opens into the cavity. A porous filter whose top end face matches with a mold cavity face at a top end of the rod-shaped casing separates gas from melt. Cavity gas from an introduction chamber introduces gas through the porous filter, and a gas pressure sensor detects pressure in the chamber. Melt pressure in the cavity is detected with a pressure transmission rod inserted into the rod-shaped casing whose top end face matches with the mold cavity face, and a pressure sensor fixed and held facing a rear end of the pressure transmission rod detects the cavity melt pressure. Cavity melt temperature is detected with a temperature sensor attached to a thin hole formed at the pressure transmission rod's center and includes a thermocouple at a top end part side of the hole.

  • Patent number: 6989356
    Abstract: To provide a lubricant for recording medium, which is advantageous not only in that it maintains excellent lubricity under various conditions for use and excellent lubricating effect over a long time, but also in that it can impart excellent transport properties and excellent abrasion resistance as well as excellent durability. For example, when C18H37—CH(CH2COOC10H6OH)COORf (wherein Rf represents a saturated or unsaturated partially-fluorinated-alkyl group) is used as a lubricant for magnetic recording medium, there can be obtained a magnetic recording medium having excellent transport properties and excellent abrasion resistance as well as excellent durability.
