A process for the preparation of poly-p-phenylene terephthalamide fibers according to the wet spinning method comprising passing an optically anisotropic solution of a poly-p-phenylene terephthalamide type polymer through a non-coagulating fluid layer and guiding the solution to a coagulating bath, characterized in that (a) filaments are taken out together with a stream of a coagulating solution from fine tube or fine hole arranged in the lower portion of the coagulating bath and the filaments are travelled through a second fine tube or fine hole arranged below said fine tube or fine hole through a space, and (b) in the fine tube or fine hole arranged in the lower portion of the coagulating bath, the stream of the coagulating solution flowing out together with the filaments is accelerated and in the second fine tube or fine hole, the speed of the stream of coagulating solution accompanying the filaments is decreased.

A liquid crystal display device (100A) of the present invention includes a liquid crystal layer (1) and first and second alignment films (12, 13) which are provided with an alignment treatment. The liquid crystal layer (1) includes, in each of the pixels, a plurality of first small sections (14a) separated by a wall (10) and the first alignment film (12) and a plurality of second small sections (14b) separated by the wall (10) and the second alignment film (13). Each of the plurality of first small sections (14a) has a first liquid crystal region (11a). Each of the plurality of second small sections (14b) has a second liquid crystal region (11b). Each of the first and second liquid crystal regions (11a, 11b) includes a nematic liquid crystal material and a dichromatic dye (21a, 21b). The dichromatic dye (21a) of the first liquid crystal region (11a) is aligned along the alignment direction of the first alignment film (12). The dichromatic dye (21b) of the second liquid crystal region (11b) is aligned along the alignment direction of the second alignment film (13).

A see-through display device (100A) according to the present invention includes a first substrate (11) and a second substrate (12) disposed opposing to each other and a light modulation layer (17) disposed between the first substrate (11) and the second substrate (12). The light modulation layer (17) contains at least two types of materials which come into a bleached state or a colored state depending on an applied voltage and which have visible light absorption spectra different from each other.

A display device includes a reflector in which a plurality of elements, each including a number of reflective regions, is arranged. In the reflector, the reflective regions of each said element are disposed so that at least part of incoming light, which has been incident on the element, is reflected by each one of the reflective regions after another and then allowed to go out of the element. At least one of the reflective regions of each said element includes: a light reflective plane; and a light modulating layer that is formed on one side of the light reflective plane so as to face the incoming light.

A simulation method for imaging of an underwater object is performed by simulating the object with a test panel having several strips of different brightness, and irradiating the test panel with a pulsed laser beam having three primary colors. From the reflected beam pulses, contrast values of the test stripes are computed for reflected pulses of each color in relation to the turbidity and visibility distance. The method may be used in conjunction with an imaging apparatus having a laser generation device which produces three primary colors of three different wavelengths; a laser beam detection device to receive the reflected beam pulses of respective primary colors, to determine intensities of the reflected beam pulses of respective primary colors, and to output three primary color signals to an image monitoring device. The imaging system may also be arranged so that a laser irradiation device, a laser beam detection device and an image monitoring device are all placed underwater in a submersible vessel with appropriate provisions for hydrostatic pressure and unmanned operation.

A thrust ball bearing unit has a pair of ringed cylindrical upper and lower casings, each casing being made of synthetic resin, a pair of upper and lower races, and a buffer interposed between the upper casing and the upper race or between the lower race and the lower casing. Alternatively, two buffers are interposed between the upper casing and the upper race and between the lower race and the lower casing respectively. The upper and lower casings have peripheral sealing portions which are in a labyrinth or contact seal relationship with each other.

An electromagnetic pickup device for use in a tone generator of an electronic piano includes a plurality of vibratory reeds and pole pieces of pickups which are so shaped that each reed and pole piece are opposed to each other in a range from the neutral position of the reed to a position within its maximum vibrating amplitude at one side. In output signals of the pickups, the balance of fundamental and odd- and even-numbered harmonics is improved to generate a tone which is close to that of a normal string piano.

A liquid crystal display panel (100A) includes: a first substrate (2) and a second substrate (3), a liquid crystal layer (1) retained between the first substrate (2) and the second substrate (3), and plurality of pixels. The liquid crystal layer (1) has a first liquid crystal region (81) and a second liquid crystal region (82) provided outside the first liquid crystal region (81). The first liquid crystal region (81) is essentially composed of a nematic liquid crystal material alone, whereas the second liquid crystal region (82) has a plurality of liquid crystal subregions (11) containing a nematic liquid crystal material and polymer-containing walls (12) formed between adjacent ones of the plurality of liquid crystal subregions (11). The plurality of pixels include pixels accounting for the first liquid crystal region (81) and pixels accounting for the second liquid crystal region (82).
