Abstract: First and second signal processing units are each configured by an IC, so that the circuit space occupying in a receiver apparatus can be reduced. The signal path can be shortened from a BPF section inputting a program signal coming from a broadcasting station to a demodulation section compared with the related art. The transmission loss on the signal path can be thus reduced compared with the related art. The possible route for noise entering from the outside to the first and second signal processing units can be made as short as possible. This enables to reduce the noise entering from the outside, and prevents the signals coming over the signal path from being attenuated by the noise so that the signal reception sensitivity can be increased.

Abstract: A support system for installing a photovoltaic power generator includes: display means for displaying an installation surface image including an installation surface on which photovoltaic modules are to be installed and a gauge disposed on the installation surface and whose actual dimensions are known, the installation surface being a region of a finite area; installation surface input means for receiving inputs for specifying the installation surface on the installation surface image displayed on the display means; installation surface shape specification means for specifying an installation surface shape on the basis of the dimensions of the gauge in the installation surface image; and module determination means for determining a type and layout of the photovoltaic modules suitable for the installation surface shape.

Abstract: A three-dimensional guiding apparatus is installed between the ground and a structure for preventing vibrations of the ground from being transmitted to the structure as much as possible. The three-dimensional guiding apparatus has a first curved guiding apparatus (21) mounted on a base (23), a second curved guiding apparatus (22) having a plane of movement which crosses the plane of movement of the first curved guiding apparatus (21), and an intermediate member (24) interconnecting the first curved guiding apparatus (21) and the second curved guiding apparatus (22). Each of the first and second curved guiding apparatus (21, 22) comprises a track rail (1) having a plurality of rolling element rolling grooves, a bearing block (10) having a plurality of rolling element rolling grooves and non-loading rolling element rolling passages, and a number of balls (9) for bearing loads between the rolling element rolling grooves in the track rail (1) and the rolling element rolling grooves in the bearing block (10).

Abstract: This manufacturing method comprises a first step in which a molten aluminum alloy is cast into casting dies into which a ball 8 forming a ball portion 1a of a ball-shank 1 in corporation with a shank 1b connected to the portion 1a is inserted as a core so that a holder 2 covering the ball portion 1a is formed leaving the connected portion of the shank 1b as it is; a second step in which the aluminum alloy for forming the holder 2 is subjected to a solution heat treatment; a third step in which the shank 1b is brought into pressure contact with the ball 8 exposed from the holder 2, electrodes 10a and 10b are held in contact with the shank 1b and the holder 2, respectively, and the ball 8 and the shank 1b are projection-welded by turning on electricity between electrodes to thereby form the ball-shank 1; and a fourth step in which an external force is applied to the holder 2 or the ball-shank 1 to thereby provide a gap between the ball 8 and the holder 2.

Abstract: The present invention relates to a three-dimensional guiding apparatus capable of bearing large loads and suitable for use in a vibration isolating structure for buildings. The three-dimensional guiding apparatus comprises a base 23, a first curved guiding apparatus 21 disposed above the base 23 and having an arcuate track, a second curved guiding apparatus 22 disposed above the first curved guiding apparatus 21 and having a plane of movement along an arcuate track which crosses the plane of movement of the first curved guiding apparatus 21, and an intermediate member 24 positioned between the first curved guiding apparatus 21 and the second curved guiding apparatus 22 and interconnecting the first curved guiding apparatus 21 and the second curved guiding apparatus 22. Each of the first and second curved guiding apparatuses 21, 22 has a track rail 1, a bearing block 10, lids 13, and a number of balls 9.
