Abstract: A jumper chip component of the present invention includes a connection conductor formed of a conductive layer over an upper face and opposite side faces of an insulating substrate, and a conductive material formed of a conductive layer between plates of the insulating substrate and on a side face at the corner of the insulating substrate so as not to be electrically connected to the connection conductor. Since the conductive material formed between the plates of the insulating substrate opposes the connection conductor formed on the upper face of the insulating substrate, the connection conductor formed on the upper face of the insulating substrate and a second conductive pattern disposed under the insulating substrate are shielded from each other by the conductive material, and good isolation is possible.

Abstract: There is provided a DNA molecule derived from a prokaryotic cell in which at least one of the DNA regions encoding NXB (N is asparagine, X is any amino acid other than proline, and B is serine or threonine) has been modified so that no N-glycosylation occurs during the expression in a eukaryotic cell, and since the DNA molecule has been modified at the N-glycosylation site, it produces a non-N-glycosylated protein, which thereby exhibits a high immunogenicity when, for example, it is allowed to produce, in a eukaryotic cell, an antigen protein derived from a prokaryotic cell.

Abstract: A radiation section of a dielectric feeder protrudes from an opening of a waveguide to improve the efficiency of receiving radio signals. An opening is provided at one end of the waveguide. A dielectric feeder held within the waveguide has a radiation section protruding from the opening. An annular wall having a bottom surrounds the opening of the waveguide. The depth of the annular wall is about ¼ of the wavelength of radio waves, and the width of a bottom surface of the annular wall is about ⅙ to {fraction (1/10)} of the wavelength of the radio waves. Consequently, the phases of a surface current that flows from the opening toward the bottom surface of the annular wall and a surface current which flows from the bottom surface of the annular wall toward the open end are substantially out of phase. As a result, the side lobes of the received radio signals are greatly reduced, and the gain of the main lobe is increased, improving the reception of radio waves transmitted from a satellite.

Abstract: An outdoor satellite broadcast receiving converter including a waveguide into which a broadcast electric wave enters and in which the broadcast electric wave travels in an axial direction as a first linearly polarized wave and a second linearly polarized wave. A first probe is disposed at a predetermined position and extends perpendicular to the axial direction into the waveguide for detecting the first linearly polarized wave. A substrate is disposed in the waveguide approximately 1/4 wavelength from the first probe and arranged to extend across an open end of the waveguide. A first shorting terminal for reflecting the first linearly polarized wave is formed on a first side of the substrate, and a second probe for detecting the second linearly polarized wave is formed on an opposing second side of the substrate. A metallic case is connected over the open end of the waveguide such that the substrate is positioned between a closed bottom of the metallic case and the first probe.
