    • A light source apparatus excites an electrodeless lamp bulb with energy of microwaves generated from a magnetron. A microwave transmission line is improved so that microwaves can be transmitted efficiently and the light source apparatus can be miniaturized. A first cylindrical member is disposed coaxially with a direction in which microwaves generated from the magnetron are transmitted, and a second cylindrical member is disposed at the center of the first cylindrical member, thereby forming a coaxial transmission line. A coaxial oscillator is formed from the position at which the microwaves are generated to a position of 1/4 of the wavelength of the microwave. Thus, a special waveguide can be removed.

    • To provide an electro-optical device, a driving method therefor, and an electronic apparatus which can accurately control the brightness of electro-optical elements in accordance with the signal level of a data signal. A brightness detection circuit 15 is provided which samples power-supply current Io every time one scan line is selected and which converts the power-supply current Io into a digital voltage signal DS having a digital value corresponding to the power-supply current Io. A light-emission-period control circuit 16 generates light-emission-period control signals H1 to Hn in accordance with a light-emission-period adjusting signal F corresponding to the digital voltage signal DS and outputs the light-emission-period control signals H1 to Hn to corresponding control-signal supply lines G1 to Gn. Further, light-emission-period control transistors of the pixels 20 which are connected to the corresponding control-signal supply lines G1 to Gn are on/off controlled, thereby controlling the light-emission period of the electro-optical elements.

    • To provide a method for manufacturing an electro-optical device that is capable of controlling more smoothly brightness as compared with a control in every one frame and preventing large current from flowing when switching frames in a peak brightness control, a method of driving the same, and an electronic apparatus. A grayscale data average value operation unit 33 performs, for each line, an average value calculation of grayscale levels of images corresponding to images of an one-frame-length and outputs, based on average value for the one frame-length, mode signals M1 to M4 for brightness control in each line. A driver input data converter 34 rewrites, based on the mode signals M1 to M4 from the grayscale data average value operation unit 33, grayscale data HD for one line among grayscale data from a frame memory 31 into grayscale data DD. The driver input data converter 34 outputs grayscale data DD which is image data for the one frame-length and whose brightness is adjusted in a signal generating circuit.

    • A data transfer control device and electronic equipment that make it possible to implement high-speed data transfer while observing restriction that prevent the traversing of page boundaries. A data transfer control device that conforms to the IEEE 1394 standard comprises a page table fetch circuit for fetching a page table from another node if a page table exists in a data buffer at the initiator, a page table creation circuit for creating a virtual page table if no page table exists, and an SBP-2 core for automatically dividing transfer data into a series of packets that do not traverse page boundaries based on the thus fetched or created page table and transmitting them. The page table creation circuit creates a page table in which a portion between a start address and a Kth page boundary is an X-type page table element, a portion between the Kth and Lth page boundaries is a Y-type page table element, and a portion between the Lth page boundary and an end address is a Z-type page table element.
