The DC module determines an average current value based on a plurality of current values over at least one cycle of an input alternating current (AC) line signal of the PFC system. The error control module generates an error signal based on the average current value. The offset module offsets a desired instantaneous current based on the error signal. The duty cycle control module controls at least one duty cycle of switches of the PFC system based on the offset desired instantaneous current.

The contacting and separating device causes the attraction belt to come into contact with and separate from the sheet stack, with different tensions set for the attraction belt at a contact position in contact with the uppermost sheet of the sheet stack and the attraction belt at a separation position separate from the sheet stack.

Abstract: Unabsorbed infrared laser light that has passed though plastic parts to be welded with a low absorption TTIr process is recirculated in an infinite loop back to the low absorption weld interface for reabsorption in the process. On each pass in the infinite loop, more infrared laser light is absorbed at the weld interface.

Abstract: A main controlling part is configured to choose and execute either a constant belt speed control which controls a driving motor (a driving source for an intermediate transfer belt) to move the intermediate transfer belt at a predetermined target belt speed or a constant motor speed control which rotates the driving motor at a predetermined target rotational speed according to a print command, and then, prior to a first-time print job, after executing a writing position correcting process while moving the intermediate transfer belt under the constant belt speed control, forms a color shift detecting image by switching from the constant belt speed control to the constant motor speed control, measures a difference between amounts of color shift, and executes a speed correcting process for correcting the target rotational speed of the driving motor in the constant motor speed control based on the measurement result.

Abstract: A seal ring whose abutment joint portion is opened is fitted into an annular gap while the abutment joint portion is substantially closed. The annular gap is formed between an inner circumferential surface of a hole portion provided in an outer circumferential jig and an outer circumferential surface of an inner circumferential jig disposed in the hole portion, and has a heating region and a cooling region. The seal ring is passed through the heating region and then passed through the cooling region in the annular gap. The outer circumferential jig and the inner circumferential jig are maintained at a constant temperature higher than a glass transition temperature of a resin material for the seal ring in the heating region, and maintained at a constant temperature lower than the glass transition temperature of the resin material for the seal ring in the cooling region.

Abstract: A nitride semiconductor chip is provided that offers enhanced luminous efficacy as a result of an improved EL emission pattern. The nitride semiconductor laser chip (nitride semiconductor chip) has an n-type GaN substrate having as a principal growth plane a plane having an off-angle in the a-axis direction relative to the m plane, and a nitride semiconductor layer formed on the principal growth plane of the n-type GaN substrate. The n-type GaN substrate includes a depressed portion (carved region), which is carved from the principal growth plane in the thickness direction, and an uncarved region, which is a region not carved. The nitride semiconductor layer formed on the n-type GaN substrate has a gradient thickness region whose thickness decreases in a gradient fashion toward the depressed portion (carved region) and an emission portion formation region whose thickness varies very little. In the emission portion formation region 6, a ridge portion is formed.

Abstract: A wafer temporary bonding method using silicon direct bonding (SDB) may include preparing a carrier wafer and a device wafer, adjusting roughness of a surface of the carrier wafer, and combining the carrier wafer and the device wafer using the SDB. Because the method uses SDB, instead of an adhesive layer, for a temporary bonding process, a module or process to generate and remove an adhesive is unnecessary. Also, a defect in a subsequent process, for example, a back-grinding process, due to irregularity of the adhesive may be prevented.
