  • Patent number: 5869812
    Abstract: A pressure regulator and steamer oven for cooking food at low pressure is provided which conserves water and space. The oven includes heating elements and a cooking cavity having a pool for holding water to be turned into steam. A pressure regulator mechanism attached to the rear of the steamer includes a reservoir and a float switch. A steam outlet conduit connects the cooking cavity to the reservoir and extends below the normal water level in the reservoir. The lower end of the conduit is blocked by water in the reservoir. The float switch is operable to turn off the heating elements when the pressure in the conduit exceeds a pre-determined level. Thus, the pressure regulator employs a water seal and float switch to help indirectly measure the pressure in the cooking cavity and control the heating elements accordingly. The reservoir is connected to the pool via an overflow which allows condensate to be recirculated to the cooking cavity.

  • Patent number: 5862302
    Abstract: A heat insulating member is disposed, enclosing a reaction tube, and a heat source is provided through a heat linearing member disposed above the reaction tube and between the reaction tube and the heat insulating member. The reaction tube is made of quartz and has a transparent portion formed in the top thereof and its neighboring thereof, and an opaque portion in the rest part of the reaction tube. In a heat treatment, when heat rays are radiated from the heat source through the heat linearing member, the heat rays pass through the transparent portion of the reaction tube to heat a wafer, but those of the heat rays reflected on the heat insulating member are blocked by the opaque portion of the reaction tube. A heat ray quantity to be passed into the reaction tube can be controlled, whereby high intra-surface temperature uniformity of the wafer can be secured, and as a result high processing yields can be obtained.

  • Patent number: 5856650
    Abstract: A method of cleaning a media preheater that is positioned in the media path of a printer is disclosed. The media preheater has a fixed heater and a movable plate array biased toward the heater such that printer media passing between the plate array and the heater is compressed therebetween and heated. The preheater may be positioned upstream of a print head and downstream of a media advancing mechanism in the media path. More than one plate may be provided in the plate array to accommodate non-planarity of the heater or the printing media. The method elevates the temperature of the contact surface of the preheater to a cleaning temperature that is greater than the operating temperature and then passes a chase sheet over the surface to remove contamination from the preheater surface.
