摘要:
The present invention provides an image heating apparatus comprising a first heater, a second heater having a heat generating distribution different from that of the first heater, a heated member to be heated by the first heater and second heater, a temperature detection element for detecting a temperature of the heated member, and a power supply controlling means for controlling power supply to the first heater and second heater on the basis of a temperature detected by the temperature detection element. The power supply controlling means serves to stop the power supply to the first heater when the temperature detected by the temperature detection element reaches a first temperature, and to stop the power supply to the second heater when the temperature detected by the temperature detection element reaches a second temperature different from the first temperature.

Lactoperoxidase, secretory component and lactoferrin are separated in high purity from milk and related materials such as whey with a single cation exchange resin. After adsorption on the cation exchange resin, elution is carried out with an aqueous solution having an ionic strength and pH selected to elute each separately. Lactoperoxidase is eluted first, secretory component second and lactoferrin last. Each is obtained in a purity of about 80% or greater. The cation exchange resin can be a cross-linked polysaccharide, cellulose or an acrylamide resin having carboxyl, sulfonic acid or phosphoric acid functional groups which may be attached with a spacer. The separated lactoperoxidase, secretory component and lactoferrin are biologically active and can be used in pharmaceuticals, cosmetics, foods, drinks and feeds.
摘要:
A temperature control device for controlling a surface temperature of a member to be heated at a predetermined temperature includes a detector for detecting the surface temperature, and a control unit for controlling current supply for a heating source for heating the member to be heated so that a result of detection by the detector is maintained at a predetermined value. The control unit controls a time of current supply for the heating source during a constant temperature control according to data relating to peak temperatures of the surface temperature during the constant temperature control.
摘要:
A test probe assembly including a plurality of electrically conductive probe arms each of which is secured to a substrate and electrically coupled to one of electrically conductive lines provided on the substrate. An intermediate portion of the arm is arranged to be resiliently deformable when a probe point which extends therefrom comes into contact with a terminal of the electronic device under test. A guide is provided on the structure on which the arms are mounted, for guiding the probe point so that movement other than reciprocation is either prevented or arrested. The resilient portion is arranged with respect to the probe point so that generation of motion other than reciprocation of the probe point is attenuated.

An image forming system including an image forming apparatus and a sheet feeding apparatus. The system includes: a first conveying unit conveying to the image forming apparatus a recording material; a second conveying unit conveying to an image forming unit of the image forming apparatus the recording material; a detector detecting a recording material type while the second conveying unit halts conveying the recording material; a first controller, based on detection by the detector, determining a speed for conveying the recording material to the image forming unit, and conveying the recording material at the conveying speed; and a second controller controlling recording material conveying speeds of the first conveying unit. Before the recording material reaches the second conveying unit, the second controller maintains a first conveying speed, and after the recording material reaches the second convey unit, maintains a second conveying speed determined by the first control unit.
摘要:
An image forming apparatus to which a paper handling unit is connected thereto is provided. The image forming apparatus detects the size of a sheet in a direction in which the sheet is conveyed for image formation. The image forming apparatus outputs sheet size mismatch information indicating that the size of the sheet does not match a predetermined size to the paper handling unit before a size detecting operation thereof has been completed detecting the trailing edge of the sheet is greater than the predetermined size.
摘要:
An object of the present invention is to provide a grain-oriented electrical steel sheet with low core loss and low magnetostriction and a method for producing the same. The grain-oriented electrical steel sheet is excellent in reduced core loss and magnetostriction while under a high flux density of 1.9 T, comprises a refined magnetic domain comprising a laser irradiated portion which has melted and resolidified to form a solidified layer, wherein the thickness of the solidified layer is 4 μm or less. The grain-oriented electrical steel sheet may further comprise a laser irradiated portion where a surface roughness Rz is small and a cross section viewed from a transverse direction has a concave portion having a width of 200 μm or less and a depth of 10 μm or less for further improvement.
