Abstract: An object of the invention is to obtain brighter display in a liquid crystal display apparatus. Light of all the wavelengths in the visible range is converted into circularly polarized light by a first polarization condition converting member, converted into linearly polarized light by a second polarization condition converting member and is modulated by a liquid crystal display device. Then, transmission and block of the light is controlled by a polarizer. Specifically, one of the dextrorotatory circularly polarized light and the levorotatory circularly polarized light is reflected by a spectral member included in the first polarization condition converting member, converted into the other circularly polarized light by a reflecting member included in the first polarization condition converting member and supplied again to the spectral member. The other circularly polarized light is transmitted by the spectral member.

Abstract: A tubular fabric is provided for forming the shaft of a prosthesis having a predetermined length and one open end, the other end of the shaft being closed for holding a coupling member except for an aperture corresponding to a portion of said coupling member which is inserted therethrough to extend outwardly. The tubular base material is selected to be longer than the length of the shaft of the prosthesis to be formed. By means of a ring the tube is annularly held together from the outside at a predetermined length so as to form a first section starting from the opening. The remaining second section is then folded back over the annular hole onto the first section. To form the shaft of the prosthesis the material is impregnated with a thermoplastic resin.

Abstract: A method of generating motion vectors from a video signal, for use in motion compensation, is applicable to interlaced video signals. In the method alternate video fields are shifted vertically so as to align the picture lines of interlaced fields, by moving the lines of one field up by half a picture line and the lines of the next field down by half a picture line. The fields of each resultant pair are compared to produce a set of motion vectors which can be used to motion compensate the video signal. The accuracy may be improved using temporal filters operative on correlation surfaces derived over tow or more field intervals.

Abstract: A specimen collecting and testing device has a housing containing a test membrane. An elongated handle having a foam member is slidably received in the housing. Once the foam member obtains a specimen, the housing is moved with respect to the handle and the foam member is moved inside the housing and slid past the test membrane. In so doing, specimen is delivered to the test membrane. The test membrane may then be observed for optical changes in the case of an instant-type test, or removed for further processing. The device is particularly useful for collecting samples of urine or oral fluid for use in drug testing, pregnancy testing and the like; for testing of specimen for any of a variety of analytes such as HIV, hepatitis B, hepatitis C, etc.; and, for collecting samples of DNA for PCR testing.

Abstract: A conventional motor controlling circuit is adapted to control an inverter that drives a permanent magnet generator as a motor to spin an engine to a speed sufficient to permit the engine to start. The commutation frequency is adjusted as a function of speed utilizing an automatic commutation frequency adjustment circuit. This circuit has multiple commutation frequency ranges that overcome a large initial bearing drag during low speed operation while still permitting high speed operation. The automatic commutation frequency adjustment circuit preferably generates first and second voltage ramps that overcome the initial bearing drag and accelerate the generator at a rate fast enough for sufficient back EMF to be generated for a closed-loop commutation phase. A speedup circuit operates during the closed-loop commutation phase to achieve the high speeds typically necessary for engine starting. The inventive circuits even permit a turbine type engine to be successfully started.

Abstract: An apparatus and a method are provided which allow two opposite plane surfaces of a body to be interferometrically measured simultaneously using light from a single light source. From a parallel light beam (P) produced by a light source (1) partial light beams (A, P) having positive and negative diffraction angles are produced using a beam splitter (8) in the form of a diffraction grating. The partial light beams strike the respective surfaces (90, 91) of the body (9) to be measured and are reflected thereat. The reflected partial light beams (A, B) are interfered with the throughgoing partial light beam (P) having an order of diffraction of zero and the thus produced interference patterns are digitized and subtracted from each other, whereby the parallelism of both surfaces (90, 91) of the body can be determined.

Abstract: A touch panel is made up of (a) an insulating substrate provided with a transparent conductive film, and (b) a flexible insulating substrate provided with a transparent conductive film. A double-sided adhesive tape combines together (a) and (b), between which is provided a spacer. Since the insulating substrate and the flexible insulating substrate are held apart by the spacer, there is a layer of air between the insulating substrate and the flexible insulating substrate. On the two transparent conductive layers are provided anti-reflective films, in the form, for example, of square islets 100 nm thick and with sides of 80 .mu.m, with a pitch Pd of 100 .mu.m and an interval Dw of 20 .mu.m. Instead of providing the anti-reflective films, holes may be selectively provided in the transparent conductive films. In this way, a touch panel can be realized which enables a bright display screen without impairing input sensitivity.

In the case of a dark display, incident light linearly polarized enters the liquid crystal layer, becoming circularly polarized light at the reflection surface, and after being reflected, when outgoing, the light becomes a linearly polarized light having a plane of polarization rotated through an angle of 90.degree. as compared with that of the incident light.

Abstract: A photoresist is applied to a first substrate made of glass or resin which has been subjected to alignment treatment. Next, the photoresist is exposed and developed by UV light so as to form a non-optical rotatory region in a stripe manner after a mask having a desired pattern is provided on the photoresist. Then, polymerized liquid crystal is applied or dropped on the substrate complex thus prepared so far after an alignment layer on the substrate is rubbed. Further, a second substrate whose surface has been subjected to alignment treatment is placed on the substrate complex such that the directions of the alignment of the two substrates are orthogonal to each other, and the substrate thus positioned is pressed against the substrate complex. Finally, the substrate complex is irradiated by the UV light to cure the polymerized liquid crystal so as to form an optical rotatory region, thereby completing an optical rotatory device.

Abstract: In signal processing circuitry using active devices, non-linearity of the device causes distortion of pure tones and the generation of intermodulation products for more complex signals. The transfer characteristics of such active devices may be considered as the accumulated characteristics of input and output filter stages separated by a non-linear region. To compensate for non-linearities and reduce intermodulation products, a drive circuit comprises pre- and post-correction filters separated by a compensating amplifier. The frequency response of the pre-correction filter corresponds to that of the input filter stage but is reversed in the frequency spectrum; with conventional I.F. the transfer characteristic of the amplifier and frequency response characteristic of the post-correction filter are the respective complements, of those of the non-linear region and pre-correction filter.
