摘要:
A transporter is adapted to transport a sheet in a first direction. At least three detectors are disposed at a downstream side of the transporter in the first direction. Each of the detectors is operable to detect passing time of a leading end edge of the sheet. A processor is operable to calculate: a first angle of the sheet with respect to the first direction based on a first difference of the passing time detected by first two of the detectors and a first distance between the first two of the detectors; and a second angle of the sheet with respect to the first direction based on a second difference of the passing time detected by second two of the detectors and a second distance between the second two of the detectors, and operable to detect a jam in case that a value of an angular difference between the first angle and the second angle is larger than a prescribed value.

A poultry raising system includes a poultry house and facilities attached to the poultry house. The facilities include lighting facilities irradiating poultry with light; and the lighting facilities include a semiconductor light source, for irradiation with light having peak wavelength in the range of 550 to 650 nm emitted from the semiconductor light source. The light in this wavelength range has positive influence on sexual maturation, appetite, need for sleep and condition of internal organs. Light of shorter peak wavelength includes ultraviolet rays that cause stress on the poultry and attract insects. Light of longer wavelength includes infrared rays that increase temperature of the poultry and of the poultry house. It is possible to emit light having peak wavelength in a specific range effective to growth and fattening. Because of high electricity-to-light conversion efficiency, high economic efficiency can be attained, and CO2 emission can be reduced. Risk of shattering of a globe by abrupt cooling can be reduced, and temperature increase in the poultry house can be prevented. Longer life reduces danger, labor and cost of exchange. Thus, meat and egg yield can be increased and economical efficiency can be improved.

The invention provides an image reading apparatus and method capable of performing skew error correction at high speed. In an image reading apparatus that conveys a stacked medium along a conveyance path, reads an image of the medium being conveyed, and discharges the medium after reading the image, the apparatus comprises calculation means for calculating the amount of skew of the medium while being conveyed, and correction means for correcting the amount of skew of the medium in accordance with the amount of skew calculated by the calculation means. The correction means comprise determination means for determining whether correction for the amount of skew should be performed or not, and control means for correcting the amount of skew of the medium. The calculation means comprise medium detection means for detecting the state of the medium conveyed along the conveyance path, and calculate the amount of skew from the detected result of the state of the medium. The control means comprise correction control means for correcting the amount of skew based on the amount of skew of the medium calculated by the calculation means when the determination means determine to correct the amount of skew. The calculation means comprise image reading means for reading an image of the medium conveyed along the conveyance path at a position closer on the conveyance path to the discharging side than the medium detection means, and calculate the amount of skew from the image data of the medium read by the image reading means.

The present invention relates to a document feeder, document feed method, and image capture device. The document feeder includes a sheet separation mechanism that restricts the number of sheets to be fed by a pull-in portion. The sheet separation mechanism includes a first separation portion that contacts the sheet, and moves so as to feed the sheet, a second separation portion, located opposite to the first separation portion, which defines a part of a sheet feed path between the second and first separation portions, and moves so as to allow the sheet to be fed, and a brake portion that variably applies to the second separation portion a load allowing the second separation portion to move.

An electrostatic charge regulator capable of holding an electric charge in a stable state and superior in environmental stability, as well as a method for making the electrostatic charger regulator and an image forming method using the electrostatic charge regulator, are disclosed. The electrostatic charge regulator has a surface layer containing a non-linear resistor on a base member such as a carrier, a developer sleeve, a developer blade, or a transfer belt. The electrostatic charge regulator is obtained by forming on the base member a surface layer by using a thin film of a composite metal oxide or by using dispersion of powder of the composite metal oxide in a high molecular compound, the composite metal oxide being prepared using at least one metal selected from Group A metals (Zn, Ti, Si, Al, Zr) and at least one metal selected from Group B metals (Bi, Sb, C, Y, La, Pr, Sc, Ce, Sn, Pb). The image forming method uses the above electrostatic charge regulator to form an image.

摘要:
An electrostatic printing method for developing an electrostatic latent image on a recording member by first developing the image by the "electrostatic developing" method in which a liquid developer comprising an insulating liquid vehicle and a solid colorant is electrostatically attracted and applied only to the electrostatic latent image, and then further developing the image, by "liquid developing" in which an insulating liquid miscible with the vehicle used in the electrostatic developing step and containing substantially no coloring matter is applied to the image and non-image areas on the recording member, whereby some of the solid colorant attracted to the electrostatic image is charged and migrates to any image portion not developed by the electrostatic developing step.
