Abstract: The present disclosure includes a case body configured to accommodate a movement, and a rotating bezel attached to the case body. The rotating bezel includes a bezel body having an annular shape, and a display plate detachably attached to the bezel body. An engagement protrusion protruding toward the bezel body and being continuous in a circumferential direction is provided at the display plate. A plastic gasket having an annular shape is disposed between the bezel body and the engagement protrusion. A first recessed portion is provided in an outer circumference of the display plate. A second recessed portion is provided in the engagement protrusion of the display plate so as to correspond to a position of the first recessed portion.

Abstract: A screening method evaluates influence of a cytotoxic factor on lymphoid cells. The method includes administering or irradiating lymphoid cells with the cytotoxic factor that injures the lymphoid cells; incubating the lymphoid cells to which the cytotoxic factor is administered or irradiated for a selected time; measuring a cell size of the lymphoid cells after the incubation; and determining influence of the cytotoxic factor on the lymphoid cells based on a change of the cell size. According to this method, influence of radiation or a drug, or efficacy of radiation, a radiation-protecting agent, an antioxidant, a radiation-sensitizing agent, a drug, or ultraviolet rays can be evaluated economically and objectively in a short period of time.

Abstract: There is provided a screening method including administering or irradiating lymphoid cells with a cytotoxic factor that injures the lymphoid cells; incubating the lymphoid cells administered or irradiated with the cytotoxic factor for a predetermined time; measuring cell size of the lymphoid cells after the incubation; and determining influence of the cytotoxic factor on the lymphoid cells based on the cell size. According to this method, influence or drug efficacy of radiation, a radiation-protecting agent, an antioxidant, a radiation-sensitizing agent, a drug or ultraviolet rays can be economically and objectively determined in a short period of time.

Abstract: The reformer 100 includes: an evaporating unit 102 that has a source fuel inlet 114 through which hydrocarbon-containing source fuel 202 is introduced, and is capable of evaporating a source fuel 202 introduced through the source fuel inlet 114; a catalyst containing unit 104 that is provided in the evaporating unit 102 and stores a reforming catalyst 108, which is capable of inducing a reaction for reforming the source fuel 202 into a reformed fuel having higher hydrogen amount; and a hydrogen outlet 118 that is provided on the catalyst containing unit 104 so as to communicate with the catalyst containing unit 104.

Abstract: Two signal lines are included among a plurality of coated signal transmission lines coupled at one end to a connector. The two signals lines are used for transmission of differential signals. The two signal lines are bundled and in contact with each other, and are coupled to the connector in this mutual contact state.
