摘要： While a recording sheet is passing through a fixing nip formed between a heating roller 41 having a heating layer and a pressing roller 42 pressed against the roller 41, a coil 43 is exited by high-frequency power from a power source and causes the layer to generate heat. An unfixed image on the recording sheet is fixed by the heat. The power source detects a zero cross timing of a rectified alternating current, detects an instantaneous value at a point a predetermined period after the zero cross timing, calculates an effective power of the alternating current based on the instantaneous value, and controls the output power to be a desired value determined based on the effective power and the surface temperature of the roller 41. Thus power input to the power source can be quickly detected and power output to the coil can be quickly and stably controlled.

摘要： A magnetic head includes a medium facing surface, a coil, a main pole, and a substrate. The main pole includes a first layer, and a second layer lying on the first layer. The first layer includes a thickness-changing portion whose dimension in a direction perpendicular to a top surface of the substrate decreases with decreasing distance to the medium facing surface. At least part of the second layer is located on the thickness-changing portion.

摘要： An image forming apparatus uses a switching element to switch current flowing to an excitation coil, so that a heating layer in a fixing member produces heat that fixes an image to a transported sheet. Based on a change in temperature of the switching element over time, a prediction unit determines, at a predetermined first time point, a predicted temperature of the switching element at a second time point at which a tip of the sheet is scheduled to arrive at the fixing member. When the predicted temperature is at least a predetermined value, a control unit controls power supplied to the excitation coil by restricting switching of the switching element and lifting the restriction, so that by the second time point the detected temperature of the fixing member reaches a temperature necessary for fixing.

摘要： The abnormality detection system is provided for detecting an abnormality of an object. The abnormality detection system includes a high-frequency power source, a primary coil, a secondary coil and a controller. The high-frequency power source supplies power. The primary coil receives the power supplied from the high-frequency power source. The secondary coil is mounted to the object in noncontact with the primary coil for receiving power supplied from the primary coil. The controller is operable to detect the power received by the secondary coil and also to determine whether or not an abnormality is present in the object based on the detected power.
