摘要:
A circuit for pattern matching on the frequency axis which inlcudes a first transformation section having an adaptive filter which is generally identical to an adaptive finite impulse response filter, but with its delay elements having been replaced by all-pass filters. The first transformation section performs frequency transformation on an input signal and is characterized by utilizing as tap coefficients for the adaptive filter, linear predictive analysis coefficients of the input speech signal. The first transformation section outputs linear predictive analysis coefficients of the frequency transformed input signal. A second transformation section is similar to the first transformation section but the tap coefficients of its adaptive filter are linear predictive analysis coefficients of a reference speech signal. A control section calculates a distance between the respective linear predictive analysis coefficients output from the first and second transformation sections, calculates controlling parameters of the filters of the all-pass filters of the transformation sections so as to minimize this distance, and generates a pattern matching residual output on the frequency axis.

An LPC analyser calculates LPC coefficients using signals bandlimited to half the sampling frequency of the LPC coefficients to be calculated. Thef calculated LPC coefficients are continuous in time scale and free from aliasing distortion. A bandlimiting circuit suitable for use in the LPC analyser is also disclosed.

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 seat belt device comprising a webbing restraining a body of an occupant to a seat and a webbing guide for guiding the webbing in such a manner that the webbing guide comes into slide contact with the webbing, the webbing guide includes an insert fitting, a covering resin which covers the insert fitting by molding, and a metal member with which the webbing comes into slide contact, and the metal member has a surface thereof which comes into contact with the webbing protruded than the covering resin toward a webbing side.
摘要:
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.
摘要:
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.
