An object of the present invention is to suppress an outflow of varnish from a lower portion of a stator core by increasing a filling rate of varnish in a slot. Provided is a method for manufacturing a stator of a rotary electric machine. The stator has a coil and a stator core in which a slot that houses the coil is formed, and a resin member of which viscosity is low at a first temperature and the viscosity is high at a second temperature higher than the first temperature is filled in the slot from an injection side. The manufacturing method includes a first step of causing a temperature difference in the stator core such that the injection side becomes the first temperature and an opposite side of the injection side becomes the second temperature, and a second step of injecting the resin member from the injection side in a state in which the temperature difference is maintained.

Method for manufacturing stator

An image reading device includes a memory unit for storing positional information of a sensor for moving by a drive unit to read an image of a document and a control unit for controlling the drive unit to move the sensor based on the positional information stored in the memory unit. The control unit drives the drive unit by an amount of driving sufficient for an image reading unit to move in a predetermined direction to abut the stop members, controls the drive unit to move the sensor so as to detect the position mark, and updates the positional information of the memory unit to a predetermined initial value based on the detection of the position mark by the sensor. The image reading device can store data of a reference position promptly even if a photo-interrupter is not provided when the data of the reference position is not stored in a memory unit.

An image forming apparatus including: an image recording portion that records an image on a sheet; a sheet stacking portion which is provided above the image recording portion and on which the sheet delivered from the image recording portion is stacked; and an image reading portion that is provided above the sheet stacking portion and reads an image on an original, the image reading portion being disposed on a rear side so that the sheet delivered from the image recording portion onto the sheet stacking portion is partially exposed to the outside on a front side of the image reading portion.

Image forming apparatus

An image feeding apparatus for feeding sheets by separating sheets one by one by a separating device has a pickup arm and a stopper. The uppermost document of stacking documents to be copied contacts and downwardly press down the pickup arm, and then the pickup arm and the uppermost document downwardly press down the stopper so as to make a passage of the uppermost document. After the uppermost document passes through, the stopper ascents by gravity in response to elevation of the pickup arm. The stopper can be reliably operated by a simple and low-cost construction.

A surface-treating agent mainly includes three constituents: a water-soluble polymer; a surface sizing agent which is a copolymer of a styrene type monomer and an anionic monomer and which mainly includes a water-soluble copolymer containing 20 to 80 weight % of the styrene type monomer; and a surface sizing agent which is a copolymer of an olefin type monomer and an anionic monomer and which mainly includes a water-soluble copolymer containing 20 to 80 weight % of the olefin type monomer. The surface-treating agent is coated and dried on a base paper for offset printing.

The present invention relates to an image reading apparatus comprising an original document conveying route, original document conveying mechanism for conveying original documents along the original document conveying route, first reading unit for reading an image on one side of the original document; and second reading unit for reading an image on the other side of the original document. The first reading unit reads an image on one side of the original document while the original document is conveyed in a forward direction at a first speed by the original document conveying mechanism, and then after the original document is conveyed in a reverse direction at a second speed, the second reading unit reads the other side of the original document while the original document is again conveyed in the forward direction. The second speed is faster than the first speed.
