Provided is a heater that is excellent in heat equalizing property even when being narrow in a sweep direction. Also provided are a fixing device, an image-forming device, and a heating device each including such a heater. A heater is configured to heat an object to be heated in such a manner that at least one of the object to be heated and the heater is swept with the heater disposed opposite the object to be heated. The heater includes a base having a rectangular shape and a plurality of heating cells each independently receiving power supply, the heating cells being disposed on the base and arranged in a longitudinal direction of the base. Each of the heating cells includes a plurality of lateral wires extending in substantially parallel with the longitudinal direction of the base and a plurality of oblique wires tilted relative to the lateral wires.

An electrode rolling apparatus according to an embodiment of the present disclosure includes a sensing unit positioned above an electrode for a secondary battery being transferred along a lengthwise direction to measure a distance to the electrode for each location along a widthwise direction of the electrode, a control unit which identifies a location of a non-coated portion formed on the electrode using information associated with the distance between the sensing unit and the electrode measured through the sensing unit, and outputs a control signal to heat a region in which the identified non-coated portion is formed, a heating unit positioned above the electrode to selectively heat only the region in which the non-coated portion is formed according to the control signal of the control unit, and a rolling unit which rolls the electrode having the selectively heated region in which the non-coated portion is formed.

An externally driven conveyor pulley with an integrated thermal control system by which the temperature of the pulley may be controlled whether the pulley is rotating or stationary. The present invention includes a rotary connection device (or plurality of such devices) designed to transfer fluid (liquid or gaseous) or electrical current into/out of a rotating object. The rotary connection device may be a slip-ring for electrical power transfer or a rotary union for liquid transfer, but any device designed to transmit fluid or electricity into a rotating object could be utilized. In one embodiment, temperature control is achieved by transmitting temperature controlled fluids through the pulley via at least one rotary connection device. In an alternative embodiment, temperature control is achieved by transmitting electricity via the rotary connection device to a temperature regulating device in the rotating object. The temperature regulating device could be any electrical heating or cooling unit.

A heating device includes a heating unit that heats a member to be heated, which is transported, as a result of a contact portion of the heating unit being in contact with the member to be heated, a heat pipe that is disposed on a portion of the heating unit different from the contact portion in such a manner as to extend in a widthwise direction crossing a transport direction of the member to be heated and that includes a crimped portion formed at a first end of the heat pipe, and a power-supply connection unit that is disposed on a second end side of the heat pipe and that is connected to a wiring line through which power is supplied to the heating unit.

A heater includes a first heat generator and a second heat generator each of which has a hypothetical center line that divides each of the first heat generator and the second heat generator into a first section and a second section. A first conductor connects a first electrode to the first heat generator and the second heat generator. A second conductor connects a second electrode to the first heat generator and the second heat generator. A first primary connector connects the first conductor to the first section of the first heat generator. A second primary connector connects the first conductor to the second section of the second heat generator. A first secondary connector connects the second conductor to the first heat generator. A second secondary connector connects the second conductor to the second heat generator.

In an image heating device having a plurality of heating blocks which are controllable independently in a longitudinal direction of a heater, an increase of the size of the heater can be suppressed, and temperatures of a plurality of heating block can be detected. A heater has a first temperature sensor corresponding to a first heating block, a second temperature sensor corresponding to a second heating block, a first electric conductor electrically coupled to the first temperature sensor, a second electric conductor electrically coupled to the second temperature sensor, and a common electric conductor electrically coupled to the first and second temperature sensors.

A heating device heats a sheet to which a liquid discharge unit discharges a liquid. The heating device includes a first heater to heat the sheet that has passed through the liquid discharge unit, a vacuum conveyor to convey the sheet that has passed through the first heater while sucking the sheet, a second heater to heat the sheet being conveyed by the vacuum conveyor, and circuitry that cause the first heater to heat the sheet when sheet data regarding the sheet satisfies a predetermined condition.

The image forming apparatus is characterized in that information about an input voltage detected on the primary side of a transformer is transmitted from a primary-side switching control unit to a secondary-side controller for controlling a heating device, and the controller controls the temperature of a heater of the heating device based on the transmitted information.

The present invention provides single units that contain a large lower chamber, and one or more display shelves above this chamber on the inside of the unit. A roller grill or other large appliance may be provided in the lower chamber, or the chamber may be left open to display large food products or other items. The shelves may be heated for keeping foods displayed on the shelves warm; however, the shelves need not be heated for food products that do not need to be kept warm. Heating elements, lights and sensors may be adjusted using electronic controls to provide optimum temperatures inside the various chambers of the display units. Display units of the present invention allow store owners to utilize the space above a roller grill or other appliance to merchandise additional food products as opposed to requiring a separate food merchandiser to occupy additional valuable counter space. The performance of the roller grills of the present invention is improved over stand-alone roller grills, thereby reducing the potential for lost sales due to food not being sufficiently heated.
