A release agent spray method and apparatus for a die casting machine. As a movable die plate is moved in a die closing direction, a spray head is moved in a perpendicular direction to a spray position. The movable die plate is stopped when it has reached a position at which the distance between the spray head and a die cavity surface of a movable die and the distance between the spray head and die cavity surface of a fixed die both become equal to a spray distance. A release agent is sprayed from the spray head onto the cavity surfaces of the movable die and the fixed die.

摘要:
The present invention relates to a combustion control device incorporated in an apparatus such as water heater and provides the combustion control device having an improved configuration with a main controller and a sub controller, capable of employing a microcomputer with lower capability as the sub controller, and ensuring higher safety than ever before. Signals indicating a combustion state of a combustion apparatus are inputted into the main controller 35 and the sub controller 36 in parallel. Upon fulfillment of a predetermined condition of stopping, the main and sub controllers 35 and 36 each output a stop signal to cut off a current to be supplied to a device driving circuit 42. The conditions of stopping in outputting of the stop signal by the main and sub controllers are such that the sub controller 36 is less apt to execute the cutoff than the main controller 35.
摘要:
A smectic liquid crystal device and process for producing the same are provided to realize uniform orientation of a smectic liquid crystal with no nematic phase in a phase sequence represented by an antiferroelectric liquid crystal; and a process for producing the same. The process comprises the steps of inducing an isotropic phase-nematic phase-smectic phase as a phase sequence of mixture obtained by adding a photopolymerizable monomer liquid crystal exhibiting nematic phase to a smectic liquid crystal; and irradiating the mixture with UV rays so that the monomer is photopolymerized into a polymer to thereby form a smectic liquid crystal medium with uniform orientation structure.
