摘要:
An FM radio receiver comprises a radio frequency tuning circuit for selecting a frequency modulated signal from an antenna and a local oscillator tuning circuit for tuning to an oscillating signal so as to convert the frequency modulated signal to an intermediate frequency. In the radio frequency tuning circuit, a capacitance variable ratio is set so as to be capable of receiving continuously the frequencies of both a first FM receiving band used in Japan and a second FM receiving band used in the US and Europe. The local oscillator tuning circuit is so constructed that an inductance value and a capacitance variable ratio can be switched so that the receiver is set to lower heterodyne for reception in Japan or upper heterodyne for reception in the US or Europe. As a result, a single receiver design can be configured for reception of FM radio broadcasting in either Japan or the US or Europe using a common front-end circuit, without increasing the number of components.

An objective of the present invention is to provide a burnishing pad, capable of removing dirt by burnishing a place (i.e., a dirty point) onto which dirt attaches to impart sufficient luster, and being biodegraded; a burnishing machine equipped with the burnishing pad; and a burnishing method using the burnishing pad. The burnishing pad of the invention is comprised of a lock-like fiber composite in which adjacent fibers are bonded at intersection thereof, wherein said fiber is at least one selected from the group consisting of a vegetable fiber and an animal fiber. And another burnishing pad is a fiber composite comprised of thick fibers of 150 μm or more in fiber diameter. These pads can be equipped with a porous supporting layer, respectively. The porous supporting layer has a mean 5% modulus strength of 20 N/5 cm width or more at 70° C. and a unit area weight of 100 g/m2 or less.

In a through anchor (10), a webbing sliding contact surface (15) is formed by bending in a curved fashion a lower edge of an opening (14) formed in a metal insert (11) toward a side. The through anchor (10) is covered over portions of the metal insert (11) other than the webbing sliding contact surface (15) with a coating resin (13). Accordingly, it is possible to provide a seat belt assembly that can continue to provide good sliding contact between a webbing guide and webbing, with simple construction.

A liquid crystal display apparatus uses a holographic optical element to split the light from a light source for generating white light to R, G and B wavelength light components. The split light components enter respective pixels of a liquid crystal cell according to the R, G and B wavelengths, thereby ensuring the display of a color image. In this liquid crystal display apparatus, unit holographic optical elements corresponding to unit pixels each consisting of R, G and B pixels are comprised of holographic optical cells for condensing respective lights of specific wavelengths on the associated pixels. Alternatively, the unit pixels are formed to have symmetrical shapes. Color filters may be provided at some of the pixels of the liquid crystal cell. Accordingly, the light incident to the pixels of the liquid crystal cell is optimized.
