Abstract: A small antenna operating in multiple modes including three or more modes. There are provided an antenna that includes a ground conductor having a ground potential, a single feeding point whose one end is formed by a part of the ground conductor, and a plurality of transmission lines to which RF power supplied to the feeding point is input, the transmission lines each radiating electromagnetic waves of three frequencies of three modes into space. These transmission lines comprises a transmission line 41 that is connected to the feeding point at one end and to a branching point at the other end, a transmission line connected between branching points, and transmission lines connected to the branching points. The lengths of the respective transmission lines are set so that impedance matching is performed at the feeding point with respect to a plurality of frequencies. The antenna is formed from an integrated metal plate.

Abstract: A wideband antenna has: a rectangular conductor sheet; a bow-tie-shaped slit formed in the rectangular conductor sheet, the rectangular conductor sheet having two apex portions defined by the bow-tie-shaped slit, the two apex portions being opposite to each other in the middle of the bow-tie-shaped slit; an auxiliary antenna element formed to extend along the bow-tie-shaped slit on both sides of one of the two apex portions; a power-feeding portion formed at the one of the two apex portions; and a grounding portion formed at an other of the two apex portions.

Abstract: The present invention relates to a method of detecting cancer by use of an oncogene, a method of screening for an active compound useful to treat and/or prevent cancer, and a pharmaceutical composition for treatment and/or prevention of cancer.

Abstract: In an antenna to be used for UWB communication, a taper slot is formed in a rectangular conductive plate, a vertical slit for separating the conductive pate is formed at the top of the taper slot, a feeding point part and a grounding point part are formed at the conductive plate and on both sides of the vertical slit, and the lower slits are formed on the oblique sides of the taper slot near the feeding point part and the grounding point part.

Abstract: A method of producing cancer cells using an oncogene, a method of detecting cancer using the cancer cell, a method of screening compounds having cancer therapeutic and/or preventive effects and a cancer therapeutic and/or preventive pharmaceutical composition. There could be provided a method of detecting cancer using the expression of HOXB13 as an indicator wherein HOXB13 gene is excessively expressed in a cell, and a cell line in which cell growth ability is changed is selected; a method of screening compounds having novel cancer therapeutic and/or preventive effects by using OXB13; a pharmaceutical composition; and a method of treating cancer using said pharmaceutical composition.

Abstract: The present invention relates to a method of detecting cancer by use of an oncogene, a method of screening for an active compound useful to treat and/or prevent cancer, and a pharmaceutical composition for treatment and/or prevention of cancer. More specifically, the present invention provides a method of detecting cancer based on the expression of the human oculospanin gene as a marker and a pharmaceutical composition containing an antibody capable of specifically recognizing human oculospanin and having cytotoxic activity against cancer cells.
