Abstract: Disclosed is a power supply including a first voltage generating unit that generates a first voltage from an external power supply; a second voltage generating unit that generates a first predetermined voltage and supplies the generated first predetermined voltage to the load; a third voltage generating unit that generates the first predetermined voltage and supplies the generated first predetermined voltage to the load; and a controller that causes the first voltage to be greater than or equal to a second voltage during a first mode, and causes the first voltage to be less than the second voltage during a second mode. During the first mode, the power is supplied from the second voltage generating unit and the third voltage generating unit to the load, and during the second mode, the power is supplied from the third voltage generating unit to the load.

Abstract: A fixing device is operable through start-up and warm-up stages and has a rotatable fixing member to fix an unfixed toner image borne on a recording medium, an opposing member to press against the fixing member and form a nip on the fixing member, a temperature detector to detect temperature of the fixing member, and a heater controlled in accordance with the temperature of the fixing member to heat the fixing member. The heater is further controlled during the warm-up stage in accordance with at least one of if the fixing member is rotating and if the detected temperature has ever arrived at a prescribed target temperature in the warm-up stage.

Abstract: A disclosed image forming apparatus includes a fixing unit configured to fix an unfixed image on a recording medium by bringing a first roller and a second roller in pressure-contact with each other; a contacting region detecting unit configured to detect a contacting region in which the first roller and the second roller are contacting each other, according to rotation of the first roller; a storing unit configured to store a contacting time in the contacting region detected by the contacting region detecting unit; and a rotation control unit configured to control the rotation of the first roller in such a manner as to change the contacting region in which the first roller and the second roller contact each other, based on the contacting time stored by the storing unit.

Abstract: Disclosed is a burner head capable of securing heat resistance and durability characteristics and improving the quality of machining at the same time, capable of easily and stably machining a material into a complicated shape. A second metal primary material of the iron family having high workability and first metal primary materials of the SUS family having high heat resistance are rolled out. Their side plate ends are butt-welded by laser to form a one-piece metal flat-plate material. A press molding machine is operated to press mold recessed portions of a pair of plate members simultaneously with cutting along a contour line. Then, folding is carried out, and they are closely joined together. A gas passage is formed by a recessed portion of the second metal primary material section. A burner port is formed by a recessed portion of the first metal primary material section.

Abstract: A measuring apparatus for a biochemical compound has a channel structure having an inlet port and an outlet port. A passageway extends between the inlet and outlet ports for passing a liquid sample therethrough. The passageway has its inside walls lined with a layer of hydrophilic material. A biosensor is provided in the passageway to detect a biochemical compound contained in the liquid sample. Preferably, the hydrophilic material comprises a metal oxide having a photocatalytic characteristic, which is illuminated with ultraviolet rays.

Abstract: The concentrations of predetermined components of a chemical solution 5 present in a cleaning bath 1 are measured by a measurement unit 11. From the results are calculated the concentrations of various chemical species. From the concentrations calculated and an experimentally obtained rate equation is calculated the treating ability of the chemical solution 5 before supplementation of said components. Then, the treating abilities of chemical solution when the components and ultrapure water are supplemented, are calculated for various cases of amounts supplemented. From these cases is determined a case of amounts supplemented in which the treating ability of chemical solution is maintained at a required level and the amounts supplemented are minimized. Next, the components and ultrapure water are supplemented in respective determined amounts via feeding pumps 21, 23 and 25.
