A nitride semiconductor substrate includes a front surface, a rear surface on an opposite side to the front surface, and a first edge portion including a chamfered edge on the front surface. A ratio of an average surface roughness of the front surface to an average surface roughness of the first edge portion is not more than 0.01. The substrate may include a second edge portion including a chamfered edge on the rear surface. A ratio of an average surface roughness of the rear surface to an average surface roughness of the second edge portion is not more than 0.01. The first edge portion has a visible light transmissivity not more than 0.2 times that of the front surface. The second edge portion has a visible light transmissivity not more than 0.2 times that of the rear surface.

摘要:
A multi-function apparatus having a wider variety of uses and easily employed when carrying a USB cable only without having a power source cord. The apparatus includes means for detecting a connection between the USB interface and the PC, means for detecting a connection to the power line, and control means for selecting a function depending on a detected state of the connection between the USB interface and PC and a detected state of the connection to the AC power line. All the functions in the multi-function apparatus are operable in a connected state of the AC power line to the AC power source, while even in an unconnected state of the AC power line to the AC power source, if the USB interface is connected to the PC, a possible operation is enabled using electric power of 5 V at 500 mA supplied from the PC.

According to this invention, the IP address and identifier of a destination apparatus are stored in correspondence with the telephone number of the destination apparatus. Input of the telephone number of the destination apparatus is accepted. Depending on whether or not the IP address corresponding to the accepted telephone number is stored, a session request is transmitted to the destination apparatus using that IP address so as to start an image communication.

An image communication apparatus, if encoded image information is received, controls the form in which the received image information is printed, in dependence upon whether a specific type of printing paper has been loaded, or in dependence upon whether color-space information of the received image information matches a prescribed color space.
摘要:
Original sheets in which both-side image information and one-side image information exist mixedly can be efficiently and certainly transmitted without an erroneous operation. A CPU discriminates the presence or absence of effective image information in images on both sides of the original sheets read by a reading circuit. In a both-side transmitting mode, the CPU selectively determines whether a both-side transmitting procedure is used or a one-side transmitting procedure is used, for transmission of the image information for each transmission of one original sheet, in accordance with a result of the discrimination. In the both-side transmitting procedure, control information such as page number, information regarding the front or reverse side of the original sheet, and the like is transmitted to a receiver station, for each side of the original sheet. In the one-side transmitting procedure, the control information is not transmitted or a proper transmitting system is used (the page number to be allocated to the front side assuming that the original sheet is the both-side original sheet is used, or the like). When the number of one-side original sheets is small, all of the original sheets may be transmitted by using the both-side transmitting procedure.
摘要:
A conventional data communication apparatus cannot set different receiving capacity for each type of received image data. To solve this problem, a data communication apparatus according to this invention notifies a partner apparatus of the receiving capacity in the normal reception mode of the apparatus at the start of communication. If high-quality transmission is designated for image data transmitted from the partner apparatus, the data communication apparatus determines whether the image data exceeds its own receiving capacity in the high-quality reception mode. If the image data does not exceed the receiving capacity in the high-quality reception mode, the data communication apparatus performs high-quality reception/recording; otherwise, notifies the partner apparatus of its own receiving capacity in the high-quality reception mode.
