Abstract: This display includes a control portion controlling a selected screen portion to display a program other than a program displayed on a nonselected screen portion if a program subsequently displayed on the selected screen portion and the program displayed on the nonselected screen portion are identical to each other.

Abstract: The object of the invention is to provide a rotary tool for friction stir welding having an excellent abrasion resistance and durability, which can attain an excellent joint characteristics. In a rotary tool 10 for friction stir welding, a shoulder portion 11 has an end surface 13 from which a prove pin 20 protrudes. The outer periphery of the prove pin 20 has a connection 15 linked to the end surface 13 of the shoulder portion 11. Pulse laser peening is applied to a base side region 22, that extends from the connection 15 to the screw part 23a. The prove pin, which is repetitiously exposed to compression load and tensile load during the friction stir welding, can maintain the surface rigidity and the toughness. The durability of the prove pin is greatly improved with the damages due to buckling or thermal deformation being restricted.

Abstract: A display includes a mode switching portion capable of switching between mixed mode performing both processing of the analog broadcasting and processing of the digital broadcasting and digital mode preferentially performing the processing of the digital broadcasting and a control portion controlling the mode switching portion so as to switch the mixed mode to the digital mode when the analog broadcasting is terminated.

Abstract: When a viewing limitation level is set from a receiver side, if the setting of the viewing limitation level is selected from a set-up screen, a TV side microcomputer displays an access code screen. When an access code is inputted, the microcomputer displays the setting select screen of the viewing limitation level of a broadcasting side. When an arbitrary viewing limitation level is selected, the microcomputer obtains the information of the viewing limitation level of a disc side from a viewing limitation level corresponding table and informs a disc side microcomputer of the information of the viewing limitation level and sets the viewing limitation level of the receiver side to the selected viewing limitation level. The disc side microcomputer sets the viewing limitation level of the disc side in accordance with the contents of the information.

Abstract: A digital broadcast reception device includes a reception means which receives a digital broadcast signal upon a physical channel which has been tuned, and an acquisition means which performs acquisition processing. Acquisition processing is processing to acquire information about virtual channels from said digital broadcast signal. Moreover, this digital broadcast reception device includes a decision means which decides whether or not said acquisition means has been able to acquire said information about virtual channels within said first timeout period, and a change means which changes the timeout period to a second timeout period, if such acquisition has not been possible. And the acquisition means performs the above acquisition processing until said second timeout period has elapsed.

Abstract: A TV system including an optical disc apparatus capable of preventing a burn-in from appearing on the screen of a display is provided, wherein a timer is started to transmit still image data from the optical disc apparatus to a TV image receiver. When a predetermined time elapsed after a still image is displayed, a CPU in the optical disc apparatus sends information of the elapsed time to a CPU in the TV image receiver. Then, the latter CPU saves the current brightness value stored in a memory and supplies a brightness value smaller than the current brightness value to a drive unit for the display, thereby enabling the image intensity to be reduced on the display and/or an OSD image to be eliminated in the still image. The image intensity on the display can be returned to the initial intensity and/or the eliminated OSD image can be recovered by pushing appropriate selection keys in an operation section.

Abstract: A system controller displays all setup items on a setup screen, at the time of a setup mode in which a setup button 18a of a remote controller is depressed, in case that it is judged that a disc is not loaded on a tray of an apparatus itself, and, in case that it is judged that the disc is loaded, then, judges a type of the disc which is loaded, and on the basis of a result of that judgment, displays only a setup item which can be used for the loaded disc, and does not display a setup item which can not be used.
