Provided is an optical fiber ribbon and an optical fiber cable, which are adaptable to manufacture at a high velocity, in the intermittent connecting type optical fiber ribbon obtained by adhering and connecting adjacent colored optical fibers by intermittent connecting portions. In an optical fiber ribbonof the present invention, since, in addition to polyol having a weight average molecular weight in a specific range, rheology control agent is contained in a specific range in a material forming an intermittent connecting portion, the Newtonian region between a low shear rate region and a high shear rate region of the material forming the intermittent connecting portioncan be adjusted. Thus, scattering of the material due to a centrifugal force generated by rotation of an application roll that applies the material at the time of manufacture and the like can be suppressed, and the application amount to colored optical fibercan be stabilized. In addition, the optical fiber ribboncan maintain suppression of such scattering and the like even in the manufacture at a high linear velocity.

Optical fiber ribbon and optical fiber cable

An optical fiber ribbon is intermittently connected in a length direction by an intermittent connection which includes a polyol having a weight-average molecular weight of 3000 to 4000 in a specific amount relative to the entire intermittent connection and which has Young's modulus at 23&#xb0; C. within a specific range. When collectively unitizing optical fiber ribbons to form an optical fiber cable, an optical fiber ribbon is formed which maintains advantages of the optical fiber ribbon and which prevents cracks of the intermittent connection and detachment of the intermittent connection from a colored optical fiber core when the cable is subjected to repetitive ironing.

The web server program causes the information processing apparatus to function as: a reception unit that receives a request from a web application executed on the web browser; an acquisition unit configured to acquire, from the request, information about a domain of the web application executed on the web browser; a determination unit that determines whether or not to permit communication with the web application executed on the web browser, based on the domain indicated in the information acquired by the acquisition unit; and a transmission unit that transmits a response to the web browser based on the result of determination of the determination unit, wherein the web server program communicates with an external apparatus connected to a network, and acquires, from the external apparatus, information used for authentication or authorization by the external apparatus.

Information processing apparatus, control method therefor, non-transitory computer-readable medium, and information processing system

An optical fiber ribbon according to the present invention includes a collective coating layer containing an ultraviolet curable resin containing amorphous PPG and an amorphous monomer, the collective coating layer formed around coated optical fibers. The collective coating layer has an equilibrium elastic modulus of 12 MPa to 20 MPa, both inclusive, and a yield point elongation of 5% to 9%, both inclusive, and the adhesion between the collective coating layer and the outermost layers of the coated optical fibers is 12 N/cm to 15 N/cm, both inclusive.

Optical fiber ribbon

An image reading apparatus including a shading correction mechanism that can be formed by fewer component parts than conventional ones, and is increased in the degree of freedom of design, thereby enabling reduction of the size and weight thereof. A contact glass guides an original to an image reading position. A glass holding member holds the glass. A line image sensor reads an image on the original conveyed to the image reading location, through the contact glass. A reference member is disposed at a location different from the image reading location on the contact glass. A moving mechanism relatively moves the line image sensor and the reference member so that the line image sensor can alternatively read the original conveyed to the image reading location and the reference member. A drive section externally drives the moving mechanism to move the line image sensor and/or the reference member.

Image reading apparatus, shading correction method therefor, and program for implementing the method

An information reading system comprising an information processing apparatus, a first information reading apparatus which is connected to the information processing apparatus and reads information on a sheet and a second information reading apparatus which is connectable to one of the information processing apparatus and the first information reading apparatus, and reads information on a sheet. The information processing apparatus comprises a control program including a first driver required to control the first information reading apparatus, and a second driver required to control the second information reading apparatus. Control information from the information processing apparatus to the second information reading apparatus is transmitted via the first driver and the second driver.

Information reading system for reading information on document

An image reading apparatus in which the position of the boundary between an image of an original and a background image, as well as a skew and the size of the image of the original, can be accurately detected even with dust on a line image sensor or on an opposing member opposite to the line image sensor. An image formed on an original is read by a reading unit, and an opposing member is arranged at a position opposite to the reading unit. A plate glass distances the original from the opposing member. Shadow portions of the read image is detected from changes in a sub-scanning direction of pixel data of a read image generated based on output from the reading unit, and boundary coordinate data of the image of the original is obtained.
