A fixing device includes two rollers to form a fixing nip and a separation plate assembly disposed near one of the rollers. The separation plate assembly includes at least one separation plate to separate a recording medium from the roller, a pair of contact members, a holding member having a rotation shaft at each end in a longitudinal direction thereof, to hold at least one separation plate and the contact members in a rotation axis direction, and a contact pressure adjuster to adjust a contact pressure of the contact members relative to the roller by bending a portion of the holding member holding one of the pair of contact members to the roller and to the opposite of the roller. When the holding member is rotated about the rotation shafts, the contact members contact the roller to separate at least one separation plate from the roller.

An image projection apparatus for projecting an image on a projection plane includes a light source; a light source housing to encase the light source; a ventilation unit to send air to the light source; and a flow path set between the light source housing and a side face of the image projection apparatus. A part of the air sent to the light source, by using the ventilation unit, is flowed into the flow path.

An image projection apparatus includes a light source, light from which is used to project an image, and a holding member configured to hold the light source. The holding member includes a handle portion, and the handle portion includes a first flow path for flowing air.
摘要:
A first sensor element outputs a first output signal in correspondence to a direction of the magnetic flux lines acting from the outside. A second sensor element outputs a second output signal associated with the first output signal in correspondence to a direction of the magnetic flux lines acting from the outside. A first conversion processing section converts the first output signal output from the first sensor element and the second output signal output from the second sensor element into the second physical quantity. A second conversion processing section converts the first output signal output from the first sensor element and the second output signal output from the second sensor element into a signal representing the rotation angle of the motor.

Disclosed are a fusion protein comprising enzyme N-acetylgalactosamine-6-sulfate sulfatase and a short peptide consisting of 4-15 acidic amino acids attached to the enzyme on its N-terminal side, a pharmaceutical composition containing the fusion protein, and a method for treatment of type A Morquio disease using the fusion protein. Compared with the native enzyme protein, the fusion protein exhibits higher transferability to bone tissues and improved, higher stability in the blood.

An exhaust recirculation control system of the internal combustion engine computes an oxygen concentration in total intake air containing recirculation exhaust gas in a cylinder and the ratio between an oxygen quantity in the total intake air and a fuel injection quantity (oxygen quantity/fuel injection quantity ratio). The computed values are compared with target values which are pre-set according to engine operating conditions and, based on the result of the comparison, at least an EGR valve or a fuel injection quantity. In order to perform such a control with high accuracy, a correcting means corrects a recirculation exhaust gas mass flow signal from a gas mass flowmeter on the basis of a predicted exhaust gas component concentration. And, by using the corrected recirculation exhaust gas mass flow, oxygen concentration in total intake air containing the recirculation exhaust gas in the cylinder and the ratio between the oxygen quantity in the total intake air and the fuel injection quantity (target oxygen quantity/fuel injection quantity ratio) are computed to perform EGR control.

An image forming apparatus including an image forming mechanism forming a toner image on a recording sheet and a fixing mechanism. The fixing mechanism includes a pair of rotating members forming a nip portion and fixing the toner image onto the recording sheet with the nip under pressure and heat, and an ejection guide member swinging relative to the fixing mechanism. The fixing mechanism further includes a plurality of separation pawl members turning about a rotating shaft, a bracket having an elastic member, a stopper pawl, and a supporting shaft configured to support the bracket. The stopper pawl further includes a pressing member and a lever moving to allow the stopper pawl to turn. The supporting shaft further includes a center axis about which the bracket is freely pivotable.

A fixing apparatus includes a fixing roller, a heat roller, a seamless fixing belt, a pressure roller, a supporting roller, and a pressure applying member. The heat roller includes a fixing heat source. The seamless fixing belt is extended between the fixing roller and the heat roller. The pressure roller pushes the fixing roller via the fixing belt to form a second fixing-process area. The supporting roller contacts inside the fixing belt and winds the fixing belt around a surface of the pressure roller to form a first fixing-process area upstream of and next to the second fixing-process area. The pressure applying member applies a pressure to the heat roller in a direction opposite to an ejection of the recording sheet from the second fixing-process area to adjust a fixing pressure of the first fixing-process area.

A belt type fixing device of the present invention includes an endless belt, a conveyor roller supporting the belt such that the belt is rotatable, a first heat source for heating the belt, a first temperature sensor, a press roller for pressing a recording medium against the belt, a hollow roller contacting the outer surface of the belt, a second heat source disposed in or adjoining the hollow roller and a second temperature sensor. The fixing device is capable of reducing a warm-up time and preventing the belt from being adhered to the hollow roller by toner and damaged.
摘要:
A fixing device for fixing a toner image formed on a recording medium includes an endless belt passed over a plurality of rollers. A press roller is pressed against a portion of the belt passed over a fix roller, which is one of the plurality of rollers. A heat source applies heat to the toner image carried on the recording medium being conveyed via a nip where the belt and press roller are pressed against each other. The nip has a width greater than 25.degree. inclusive in terms of a circumferential angle as seen from the axis of the fix roller. The fixing device prevents a recording medium from wrapping around the belt and broadens a parting temperature range.
