An Llayer arranged at a second position from the end faces of the resonator is made of a film having an optical film thickness thinner than &#x3bb;/4.

Semiconductor laser element and semiconductor laser device

A history of transmission/reception via a line is stored in association with the line, and it is detected whether or not a communication apparatus is physically connected to the line. Then if the line is detected to be disconnected, it is determined whether or not a history of transmission/reception regarding the disconnected line is stored. If it is determined that the history of transmission/reception regarding the disconnected line is stored, notification is given to a user that the line is disconnected.

Communication apparatus, method of controlling the same and storage medium

The present invention provides a communication apparatus configured to transmit image data through a network and a control method therefor. The apparatus stores, as transmission history, a destination and a communication mode for IPFAX at a time of transmission, reads the destination and the communication mode, and transmits image data to the read destination in the read communication mode.

Communication apparatus, method of controlling the same, and storage medium

This invention provides a communication apparatus, which designates, when a line designated as that used for a specific application falls into a disabled state, another line as a new line used for the specific application. To accomplish this, even when at least one of a plurality of lines falls into a disabled state, and when the line in the disabled state is designated as a line used for the specific application, the communication apparatus designates a line other than the line in the disabled state among the plurality of lines as a new line used for the specific application.

Communication apparatus and control method thereof

An image communicating apparatus capable of transmitting/receiving image data via a high-speed digital line network determines whether a transmission destination device is busy. If it is determined that the transmission destination device is busy, the image communicating apparatus redials the transmission destination device a preset number of times. If it cannot be determined that the transmission destination device is busy and transmission has not ended normally, the image communicating apparatus redials the transmission destination device by limiting a redial count.

Image communicating apparatus, control method therefor, and storage medium storing program

There are provided a communication apparatus capable of performing voice communication via an IP network, and performing FAX communication using a deemed voice, and a method of controlling the same. At the time of reception of an incoming call, the apparatus determines whether an incoming voice communication call or digital data has been received. If it is determined that the incoming voice communication call has been received and there is an already connected voice communication section, the SLIC superimposes a tone of a notification of the incoming call during voice communication on a voice during voice communication. When the telephone instructs to switch to the incoming call, the apparatus establishes a new session for the incoming call, and controls the selector to connect the already connected voice communication session to the digital modem to send a holding tone.

An image communication apparatus enabling reduction of line occupation time and communication charge. The image communication apparatus generates image data for high-speed transmission and image data for low-speed transmission from input image data. Before transmission of image data, it is determined whether high-speed transmission of the image data is possible. When the high-speed transmission of the image data is determined to be possible, the image communication apparatus selects the image data for high-speed transmission, whereas when the same is determined to be impossible, the image communication apparatus selects the image data for low-speed transmission.

Image communication apparatus, method and a non-transitory computer-readable storage medium to generate both image data beforehand for low and high speed facsimile transmission

A communication apparatus includes a control unit including a controller configured to control the communication apparatus, a first communication unit configured to perform communication under control of the controller, and a second communication unit including a subcontrol unit and configured to perform communication under control of the subcontrol unit, wherein a load condition of the controller is determined, and one of the first communication unit and the second communication unit is selected to perform communication processing based on the determined load condition.

Communication apparatus and method for controlling communication apparatus

A data communication apparatus and an electronic mail data producing method are provided that are capable of allowing a file name to be easily added to a file attached to an electronic mail and also allowing a file name to be added to a file attached to an electronic mail, which is commensurate with the contents of the date to be transmitted. A CPU of the data communication apparatus combines a page number allotted to each of the images converted into files with the subject of the electronic mail that is inputted, to generate an attached image file name, and transmits the electronic mail with the image data in the form of files attached thereto together with the generated attached image file names. Therefore, it is not necessary to input the name of an image file attached to an electronic mail, which facilitates the operation of transmitting an electronic mail and enables giving a file name that enables the receiver of the electronic mail to easily recognize the contents of the attached image file.

Data communication apparatus and electronic mail data producing method

An image processing apparatus includes a print region storing section, image data producing section, image region detecting section, comparing section, deciding section, and image data processing section. The image data producing section stores a print region of a medium. The image data producing section produces image data. The image region detecting section detects an image region of the image data. The comparing section compares the print region with the image region, and outputs a comparison result. The deciding section determines based on the comparison result whether the image data should be printed in a borderless printing mode. The image data processing section processes the image data such that the image data is ready to print, the image data being processed when the comparison result indicates that the image data should be printed in the borderless printing mode.
