Abstract: A lead member includes a lead conductor having a first main surface and a second main surface opposite to the first main surface. The lead member includes a resin portion that covers the first main surface, the second main surface, and two side surfaces that are between both ends of the lead conductor, while exposing the both ends of the lead conductor in a first direction. The lead conductor includes a metal substrate and a surface treatment layer formed on at least a portion of a surface of the metal substrate, the surface treatment layer including chromium, oxygen, and fluorine. A moisture content of a portion of the surface treatment layer exposed from the resin portion, as measured by coulometric Karl Fischer titration at a vaporization temperature of 220° C., is 5.0 ?g/cm2 or less.

Abstract: A radiotherapy apparatus controlling method according to the present invention includes controlling an imager driving unit to move an imaging unit to a position, and to image a transmission image by the imaging unit based on a radiation emitted from a first irradiating unit; and controlling the imager driving unit to move the imaging unit to a position, and to image a transmission image based on a radiation emitted from a second irradiating unit. According to such a radiotherapy apparatus controlling method, it is not necessary to separately provide an imaging unit which images the transmission image using a first radiation emitted from the first irradiating unit and an imaging unit which images a transmission image from the radiation emitted from the second irradiating unit, and a radiotherapy apparatus can be manufactured to be cheaper.

Abstract: An HF frequency tuning device includes a resonance cavity in which an HF is introduced, a phase detecting section which generates a sign data representing a sign of a phase difference between a traveling wave and a reflected wave included in the HF in the resonance cavity. The frequency of the HF is repeatedly shifted by a first pitch. The direction of the shift is determined by the sign data for reducing the phase difference. When the sign is inverted, the frequency of the HF is repeatedly shifted to the opposite direction by a second pitch smaller than the first pitch until the sign is inverted again. By this tuning process, the fine tuning of HF can by achieved in a short time.

Abstract: A radiation irradiation method includes the steps (a) and (b). The step (a) is the step of irradiating a first part of a subject with first radiation radiated in a radial pattern from a first point. The step (b) is the step of irradiating a second part different from said first part of said subject with second radiation radiated in a radial pattern from a second point. A first position of said first point relative to said subject correspond to a second position of said second point relative to said subject.

Abstract: A method and a system for controlling the mixing of raw materials for cement. Component contents of a sample material is obtained at an exit side of a mill system to obtain measured modulus values of hydraulic modulus HM, silica modulus SM, and iron modulus IM of a raw material mixture. Estimated modulus values of the component contents is determined and based on current takeout amounts of the raw materials, a mill system passage characteristic model, a component analyzer passage characteristic model, and preset component contents of the raw materials. Modulus deviation values are calculated based on differences between the estimated modulus values and the measured modulus values, and is passed through a noise removal filter. Future modulus values of the component contents are then calculated based on the raw material takeout amounts, and the preset raw material component contents. To determine predicted modulus values for calculation of updated takeout amounts.
