  • Patent number: 6468352
    Abstract: Particles are cooled at a particle introducing section by a cooling device. A vapor of modifying agent for modifying the particles is produced by heating the modifying agent in a vapor producing chamber by a heating device. Further, a supersaturated vapor of the modifying agent is produced around the particles by mixing the cooled particles with the vapor of the modifying agent. The modifying agent condenses on the surface of the particles by the production of the supersaturated vapor, and consequently, a film of the modifying agent is formed on the surface of the particles. A thick film of the modifying agent can be formed if this film forming step is carried out repetitively. Thus, modified particles having formed thereon a thick uniform film of the modifying agent can be produced by quite a simple manipulation in a very short time.

  • Patent number: 6462741
    Abstract: A presenting time for an animation is determined as follows for each of a plurality of frames of the animation in passage of time at a prescribed speed which can be changed as desired. First, for each of the plurality of frames, a signal indicating a timing corresponding to a boundary between adjacent frames is applied. Then, in accordance with the applied timing indication signal, a presenting time is determined and recorded onto a medium corresponding to each frame. A producer operates a keyboard, mouse or the like to input the timing indication signal at an arbitrary timing. In addition, the timing indication signal is input at a timing determined in accordance with the regenerated guide track information while guide track information (information to be referenced for identifying the aforementioned boundary) is regenerated at a regeneration rate in accordance with a prescribed speed.

  • Patent number: 6453802
    Abstract: A connectionless steam cooker has an insulated housing that surrounds an internal cooking compartment accessible through a door. A supply of water is held in the compartment and immerses a plate-like heating element mounted at the floor, preferably of the electrical resistance type. A steam outlet located above the maximum water level is in fluid communication with and adjacent an electrically-operated solenoid valve that is normally open to atmosphere. A temperature sensor in close physical proximity to the steam outlet and the solenoid valve closes the solenoid wherein the sensed steam temperature is at or above a set level. The outlet steam is also connected to a pair of water column pressure-responsive microswitches. One microswitch controls power to the heating element. It is set closely, e.g. to cycle between ON and OFF in response to a sensed pressure range of 1 and 3 inches of water W.C.) The second microswitch responds to a higher set pressure (e.g. 9 inches W.C.

  • Patent number: 6456359
    Abstract: A PBS for guiding light from a light source to a DMD as light modulating means as well as for guiding light modulated by the DMD to photographic paper is provided on an optical path between the light source and the DMD. The DMD is arranged so that light from the PBS perpendicularly enters itself, and is equipped with a plurality of micromirrors which swing in accordance with image data. This arrangement allows optical components to be disposed so that an angle of incidence of light with respect to the DMD is 0°, thereby enabling tight layout of the light source section. In other words, there is no need to spread the optical components around the light modulating means like in the conventional cases where an angle of incidence with respect to the light modulating means is more or less required.
