Abstract: There is provided a frequency down converter group including frequency down converters corresponding to a plurality of input terminals, and IV converters being paired therewith; and a voltage-controlled oscillating circuit group including voltage-controlled oscillating circuits corresponding to a plurality of frequency bands, and VI converters being paired therewith. The IV converters and VI converters are electrically connected to a common current signal node. The demodulator is capable of generating a local signal having a desired frequency and converting an RF modulated signal into a signal having a frequency of a baseband signal by use of a smaller number of voltage-controlled oscillating circuits, by changing combination of the pair of the operating frequency down converter and the IV converter and the pair of the voltage-controlled oscillating circuit and the VI converter depending on the frequency bands.

Abstract: A seat belt system for a vehicle, for restraining an occupant in a seat disposed in a compartment of the vehicle. The vehicle comprises an opening formed on at least one side of the vehicular body, and a first door moving between a first state where the first door closes at least a part of the opening and a second state where the first door opens the opening. The seat belt system includes a belt webbing, a retractor disposed in the first door for retracting the proximal end of the belt webbing, and a sliding device fixed on a lower edge of the opening, to which the distal end of the belt webbing is attached. The sliding device permits the distal end of the belt webbing to slide along the lower edge of the opening between a forward position and a rearward position. The distal end of the belt webbing is located at the rearward position when the first door is in the second state.

Abstract: One large opening (1) formed in a car body side portion and continuous in a back-and-forth direction is opened and closed by front and rear side doors (11, 12). When the side doors (11, 12) are closed, a lap portion (15) is formed where a rear end of the front side door (11) overlaps a front end of the rear side door (12) externally in a direction of car width. A reinforcing member (25) extending in a vertical direction is disposed on the rear side door (12) in the vicinity of the lap portion (15). The rear end of a front impact bar (27) disposed in the front side door (11) extends to the lap portion (15). The front end of a rear impact bar (26) disposed in the rear side door (12) is connected to the reinforcing member (25).

Abstract: In an artificial dental root having a first end, a second end which is opposite to the first end and which is to be embedded into a jawbone, and a shank between the first and the second ends, a thread portion is formed on the shank and has a pitch which is not smaller than 2 millimeters. The pitch is preferably between 3 and 4 millimeters. The thread portion comprises a screw thread which has the above-mentioned pitch, a width, and a height. At least one of the width and the height of the screw thread is reduced in a direction of the second end. A rotation stopper member is formed on the second end and may be a groove and/or a projection. The shank may be reduced in diameter as it is near to the second end.
