IPC: F24H3/04
Filed: 1986-01-30
Abstract: PURPOSE:To sensitively detect the presence or absence of any one warming oneself in a foot warmer, and to decrease the temperature of the foot warmer when no one is present therein thereby to save wastful consumption of power by providing a blower so that air is sucked up from the center of the lower surface of a heating unit and blown off toward the outer periphery of the foot warmer. CONSTITUTION:Whether the output of a heater 1 holds a predetermined value or it is under a varied unstable condition, is judged by control processing such as the secondary side voltage checking of a current transformer within an outside control unit. For example, if the output condition of the heater is as predetermined, it is judged that there is no one who warms oneself in a foot warmer and a temperature control to lower the temperature of the foot warmer to a temperature which is lower than the initially set temperature. In this case, air of a heating unit 7 is blown off through a suction port 62 toward the outer periphery of the foot warmer by means of a blower 2, and circulates around the entire periphery of the foot warmer and is made into a flow sucked within the heating unit 7 through a suction port 61 at the central part of the foot warmer, whereby the disturbance of the output of the heater 1 due to the entrance of one from the outer periphery or generation of a clear ance can be caught precisely.

Accordingly, ultrasonic vibration from the oscillator 48 is imparted to a vibration medium 45 from the vibrator 46, and the branch part 13 and confluence part 19 arranged in the medium 45 are uniformly vibrated through the medium 45. Consequently, the coating material passing through the branch part 13 and confluence part 19 is vibrated and not settled.

Title: Formation of iron oxide film
Inventor: SHIYOUNO TOMOAYA
IPC: C23C8/40
Filed: 1995-02-07
Abstract: PURPOSE: To reduce the riskiness of treating work by allowing an iron base metal from which natural oxide film is removed to contact with water, steam or an aq. solution having a specified pH value to form an iron oxide film on the surface of the iron base metal. CONSTITUTION: In this formation, a natural oxide film on the surface of a component consisting of iron or an iron alloy is removed in water, steam or an aq. solution at >=50 deg.C or alternatively, mechanically removed in the atmosphere or a non-oxidizing atmosphere. Then, the resultant component is allowed to contact with water, steam or an aq. solution having a pH value of 6 to 13 at 50 to 130 deg.C to form an iron oxide film consisting essentially of Fe3 O4 on the surface of the component. When iron ions are added to this aq. solution, the iron oxide film forming rate is increased, and also, at the time of applying a polarity alternating voltage to the component, the supply of iron ions, hydroxide ions and oxygen is promoted to form an iron oxide film having a large film thickness.  Since any high temp. strong alkali solution is not used in this formation, the treating work is safe.
