Abstract: A vehicle seat includes a seat back and a cushion seat. The cushion seat includes a seat frame, a cushion pad portion above the seat frame, a first submarining suppression portion below the cushion pad portion, and a second submarining suppression portion below the cushion pad portion, the second submarining suppression portion arranged on a side of the first submarining suppression portion closer to the seat back.

Abstract: A connection bar mounting structure includes: link members, each including a first hole part in a middle part; vehicle members, each configured to rotatably support each link member at a first fixation part of each link member; side frames, each configured to rotatably support each link member at a second fixation part of each link member opposite to the first fixation part across the first hole part; and a connection bar, each end thereof fixed to the first hole part of each link member. Each link member has a first bending rigidity reduced section between the middle part and the first fixation part and a second bending rigidity reduced section between the middle part and the second fixation part, the first and second bending rigidity reduced sections having bending rigidity smaller than those of the middle part, the first fixation part, and the second fixation part.

Abstract: A radio communication apparatus configured to perform frequency conversion on a first transmission signal modulated at a frequency in a specific frequency band into a second transmission signal having a frequency in a transmission frequency band, in which the apparatus includes: a circuit configured to generate a first calibration signal having a frequency higher than a highest frequency in the specific frequency band, and a second calibration signal having a frequency lower than a lowest frequency of the specific frequency band; a circuit configured to add the first and second calibration signals to the first transmission signal; a circuit configured to estimate a phase at a center frequency in the specific frequency band of the first transmission signal, and output a phase correction coefficient corresponding to the estimated phase; and a circuit configured to correct the phase of the first transmission signal, based on the phase correction coefficient.

Abstract: The invention comprises a compact, reliable, and handy electrical connector for connecting two flat cables to a circuit board, by connecting the electrical circuits on the front side of the circuit board to one flat cable and the electrical circuits on the rear side of the circuit board to another flat cable.

Abstract: An electrical connector on which a first circuit board is mounted has a series of contact elements therein each with an end portion that projects from the connector, the end portion being soldered to a second circuit board. The connector has a slit parallel to each of the peripheral edges thereof. The slit is separated by bridge portions to form a plurality of openings. The locking means is provided with a protruded edge that engages with the surface of the first circuit board and hook portions each of which can be inserted into a corresponding opening and slid therein for preventing separation of the first circuit board and the connector.

Abstract: A method for the removal of mercury contained in a sulfur dioxide-containing gas which comprises contacting the sulfur dioxide-containing gas with an aqueous thiourea solution which optionally contains an acid at an acid concentration higher than one normal to selectively absorb mercury in a vapor state.
