摘要:
A dielectric waveguide designed to avoid the influence of reflection of electromagnetic waves at connected portions of dielectric strips and to have an improved characteristic. The distance L between connection planes between pairs of dielectric strips adjacent in the direction of propagation of an electromagnetic wave is set to an odd number multiple of ¼ of the guide wavelength. Reflected waves are thereby superposed in phase opposition to each other to cancel out. In this manner, propagation of a reflected signal to ports is limited.

A dielectric waveguide designed to avoid the influence of reflection of electromagnetic waves at connected portions of dielectric strips and to have an improved characteristic. A third dielectric strip is inserted in a part of a connection section at which a first dielectric strip and a second dielectric strip are connected to each other, and the distances between the three connection planes in said connection section are determined so that a wave reflected at the connection plane between the first and third dielectric strips, a wave reflected at the connection plane between the first and second dielectric strips, and a wave reflected at the connection plane between the second and third dielectric strips are superposed with a phase difference of 2&pgr;/3 from each other. Alternatively or in addition, the distance between the first-second dielectric strip connection plane and the first-third dielectric strip connection plane is set to ⅙ of the guide wavelength of an electromagnetic wave propagating through the dielectric strips, and the distance between the first-second dielectric strip connection plane and the second-third dielectric strip connection plane is set to ⅙ of the guide wavelength. Reflected waves are thereby superposed in phase opposition to each other to cancel out. In this manner, propagation of a reflected signal to ports is limited.

A method of processing a photosensitive glass includes exposing. Photosensitive glass by radiation from a laser whose oscillation wavelength lies within the range of wavelengths of exposing light to which the glass responds. Then, the exposed portions 1c are thermally developed and etched. Since a laser beam propagates with a high rectilinearity, the front and rear surfaces of thick photosensitive glass can be exposed without producing dimensional errors. Therefore, the etching accuracy is improved. Especially, where the front and rear surfaces of photosensitive glass are etched, both surfaces can be processed so as to form the same shape in them accurately. In addition, because almost all the energy of the laser radiation is used for exposure of the photosensitive glass, the energy is not wasted and so the efficiency is high.

A magnetic recording device includes a movable body having a magnetic layer and an arrangement for writing a predetermined magnetic image on the movable body. A developing arrangement is controlled to blow a magnetic fluid onto the movable body in order to develop the magnetic fluid. The magnetic fluid is circulated except at times when the image is being developed by the magnetic fluid.

In a method and device for providing a visible image on a magnetic layer, the layer having a magnetic image thereon, the magentic layer is moved at a distance spaced from the top surface of a body of a magnetic fluid. The distance is sufficiently small that magnetic fluid from said body can be attracted to contact portions of said magnetic layer having a magnetic image thereon, by magnetic attraction, while the fluid is not attracted to portions of the layer that do not have a magnetic image.

An exhaust gas purification device includes a NOx adsorption catalyst (36) and HC supply means (48) for adding HC to the exhaust gas flowing to the NOx adsorption catalyst (36). The HC supply means (48) is controlled first to supply an amount of HC required to keep the temperature of the NOx adsorption catalyst (36) at a second temperature which is derived by subtracting a temperature rise caused by rich spike from a first temperature predetermined as a temperature necessary for S purge, thereby increasing the temperature of the NOx adsorption catalyst (36), and then to additionally perform the rich spike for the S purge while continuing the HC supply.

An image processing method using a computer includes extracting vertex coordinates (S13) of a triangular-shaped polygon, setting a region (S14) surrounding the triangular-shaped polygon (TP) on the basis of the vertex coordinates, measuring a distance (S15) from a lattice point included in the region to the triangular-shaped polygon (TP), and drawing a graphic figure (S21). The graphic figure is drawn on the basis of the distance from the lattice point to the triangular-shaped polygon (TP).

摘要:
Trying on the clothes is simulated by processing an image sequence by using a posture dictionary, and a three-dimensional figure, obtained in advance, of a person who wishes to try on clothing. The process includes estimating the posture of the person, and simulating the motions of the clothes, in agreement with estimated time series posture data. A virtual modeling apparatus comprises an imaging device configured to take an image sequence, a posture-estimator which estimates the posture of a person in the image sequence from the three-dimensional figure data of the person and from data for various postures, a posture corrector which generates smooth and natural posture time series data from the time series of estimated postures, a clothes simulator which calculates the motions of the clothing being modeled, and a display device which displays images of the person as if they were actually wearing the clothing.
