摘要:
A vertically alignment mode liquid crystal display device having an improved viewing angle characteristic is disclosed. The disclosed liquid crystal display device uses a liquid crystal having a negative anisotropic dielectric constant, and orientations of the liquid crystal are vertical to substrates when no voltage being applied, almost horizontal when a predetermined voltage is applied, and oblique when an intermediate voltage is applied. At least one of the substrates includes a structure as domain regulating means, and inclined surfaces of the structure operate as a trigger to regulate azimuths of the oblique orientations of the liquid crystal when the intermediate voltage is applied.

Disclosed is a cleaning article to be used while being attached to a holder. The cleaning article includes: a base sheet; a brush portion provided on one side of the base sheet; and a holding sheet provided on the other side of the base sheet. The base sheet, the brush portion and the holding sheet are fusion-bonded together to have at least two fusion-bonded portions which are spaced apart from each other and define a holding space between the base sheet and the holding sheet for accommodating the holder. One of the base sheet, the brush portion and the holding sheet is provided with a color different from those of the others so that the fusion-bonded portions have a color different from that of the holding sheet.

A cleaning tool that includes an elongate cleaning element holder and a cleaning element to be attached to the cleaning element holder is provided. The cleaning element holder has a grip to be held by a user and two holding elements extending parallel in a longitudinal direction from the grip. The holding elements are adapted to be inserted into an insert region of the cleaning element to thereby hold the cleaning element. The two holding elements of the cleaning element holder can be rotated in parallel toward each other around a longitudinal axis of the cleaning element holder on a rotation axis disposed between the holding elements. As a result, through the rotation of the two holding elements inserted into the insert region, the sectional shape of the cleaning element can be changed in a direction crossing the longitudinal direction of the cleaning element holder.

摘要:
Moirés due to interference between two liquid crystal display panels in a display device which achieves three-dimensional displaying by using two liquid crystal display panels is to be prevented. By disposing a lenticular lens array between an upper liquid crystal display panel and a lower liquid crystal display panel, moirés and image blurs are prevented. This configuration can prevent the luminance levels and contrast of images from dropping.

There are provided an electrode tip dressing apparatus and an electrode tip dressing tool for resistance welding, which are miniaturized by reducing a rotational driving-force of a dressing tool. By adjusting a curvature radius of a dressing portion 4 of a dressing tool 2, a contact width, wherein a top electrode tip 5 abuts to the dressing portion 4 of the dressing tool 2, is adjusted from a rotational center of the dressing tool 2 to the outer side of the dressing tool 2. Dressing work done with the dressing tool 2 is thus made to be constant at the whole area of the dressing portion 4, from the rotational center of the dressing tool 2 to the outer side of the dressing tool 2. Accordingly, excess dressing work, which brings decline of productivity, can be avoided, thus enabling to dress the top electrode tip 5 with the minimal dressing work. A rotational driving-power of the dressing tool 2 is thereby reduced, enabling to labor-save and miniaturize the electrode tip dressing apparatus.

In a receiving apparatus in a multicarrier communication system for transmitting data independently via a plurality of subchannels, (1) a soft-decision target value lnD0 is calculated, this being the difference between the probability that data received from a subchannel of interest is one of two values and the probability that the data is the other of the two values; (2) a non-linear operation is performed using degrees of coupling α1, α2 with other subchannels and soft-decision target values lnD1, lnD2 that have entered from receivers on the other channels, and the soft-decision target value lnD0 on the subchannel of interest is adjusted subchannel by subchannel based upon results of the non-linear operation; and (3) a decision is rendered on receive data based upon the soft-decision target value that has been adjusted.
摘要:
The present invention intends to provide a two-dimensional photonic crystal having a high level of mechanical strength and functioning as a high-efficiency resonator. The two-dimensional photonic crystal according to the present invention includes a slab layer 31 under which a clad layer 32 is located. In the slab layer 31, areas 35 having a refractive index different from that of the slab layer 31 are cyclically arranged to create a two-dimensional photonic crystal. A portion of the cyclic arrangement of the areas 35 are omitted to form a point-like defect 36. This defect 36 functions as a resonator at which a specific wavelength of light resonates. An air-bridge cavity 37 facing the point-like defect 36 is formed over a predetermined range of the clad layer 32. In this construction, the clad layer 32 supports the slab layer 31 except for the range over which the air-bridge space 37 is formed. Therefore, the two-dimensional photonic crystal has a high level of mechanical strength. The presence of the air-bridge space 37 under the point-like defect 36 makes it easy to confine light at the point-like defect 36 by the difference in the refractive index between the slab layer 31 and the air. Thus, the point-like defect 36 functions as a high-performance resonator.
