  • Patent number: 11058894
    Abstract: To provide a particle beam therapy device that expands an irradiation field while avoiding an increase in size of a scanning unit or an irradiation device including the scanning unit. A shift unit 36 is provided downstream of a scanning unit 34. The shift unit 36 deflects a carbon beam as a particle beam to shift the irradiation field, thereby forming an expanded irradiation field. The shift unit 36 includes a first shift electromagnet 42 that shifts the irradiation field in a Y direction and a second shift electromagnet 44 that shifts the irradiation field in an X direction. The scanning unit is dynamically controlled, and the shift unit 36 is statically controlled.

  • Patent number: 7116730
    Abstract: A demodulation apparatus includes an A/D converter for sampling and quantizing a baseband signal, and a demultiplexer for multiple-separating output signals of the A/D converter into two outputs. A first branch unit splits one of the two outputs of the demultiplexer into M outputs, where M is an integer equal to or greater than 2. Also, M/2 delay units delay M/2 outputs of the first branch unit. A second branch unit splits the outputs of the demultiplexer into M. The demodulation apparatus further includes first M/2 transversal filters, second M/2 transversal filters, and third M transversal filters. First M/2 adders each adds one of the output signals of the first transversal filters and one of the output signals of the third transversal filters, and second M/2 adders each adds one of the output signals of the second transversal filters and one of the output signals of the third transversal filters.

  • Patent number: 7053871
    Abstract: A method of driving a gas discharge tube is provided. Each field of images is divided into three periods for luminescence-rest, luminescence-preparing, and luminescence steps. During the luminescence-rest step, two voltages whose amplitudes are the same and constant are applied to two sustaining electrodes composing each pair, so that the sustaining electrodes rest the discharge. During the luminescence-preparing step, two voltage pulses whose phases are the same are applied to the two sustaining electrodes composing each pair and a voltage to cause a preparatory discharge is applied to an auxiliary electrode. And during the luminescence step, two voltage pulses whose phases are mutually shifted are applied to the two sustaining electrodes composing each pair, so that the sustaining electrodes cause discharges for the luminescence.

  • Publication number: 20030063050
    Abstract: Disclosed are a gas discharge tube used for the backlight of a liquid crystal display (LCD) or the like and a drive method for the same. A flat type gas discharge tube comprises two plane glasses, a barrier and at least one electrode group comprised of a plurality of parallel electrodes. Voltages are applied to each electrode group in one discharge period in such a way that discharges of a rare gas dispersed spatially and along the time are allowed to occur. Even when a single gas discharge tube is used for the backlight of an LCD having a large display area, therefore, it does not suffer luminance unevenness and the locations of discharge can be dispersed spatially and along the time, thus ensuring a high emission efficiency. As the backlight does not require a light guide plate or a diffusion sheet, its manufacturing cost becomes lower.

  • Patent number: 6528952
    Abstract: The PDP of the present invention has first, second and third electrodes. Intervals between the first and second electrode is 0.2 mm or more. A plurality of third electrodes are formed. Protrusions which are shorter than ribs are formed between the plurality of third electrodes. The plurality of third electrodes are connected, in part, to one another or at least connected in part, such that they form a network. In the driving method of the PDP of the present invention, a self-erasing discharge is generated, and subsequently when a potential difference between the electrodes is increased, using the self-erasing discharge as a trigger, discharge is generated and light is emitted.
