Title: Digital video tape recorder for digital hdtv
Inventor: WINE CHARLES MARTIN
IPC: H04N7/52
Filed: 1994-01-19
Granted: 2004-03-30
Abstract: A digital video tape record/playback apparatus (Fig. 10) for processing a high definition television signal includes provision for controlling the occurrence of high priority (HP) image information. Such information is selectively recorded at normal speed in tape tracks within predetermined regions (HP1-HP5) so as to appear along a tape head scanning path associated with predetermined tape playback speeds greater than normal (e.g., 20x normal). Input high priority data cells may be reordered or duplicated for recording in the predetermined tape regions in other than received order. In either case, the input datastream is massaged to produce a viewable image in a fast playback mode. In an illustrated system for receiving an MPEG coded datastream, an output datastream at greater than normal playback speed comprises either intracoded I-frame data cells only, or a whole Group of Pictures (GOP).

The improved knee orthosis has a thigh cuff with a medial portion, a lateral portion and an anterior portion, a shank cuff with a medial portion, a lateral portion and an anterior portion, a medial hinge for linking the medial portion of the thigh cuff to the medial portion of the shank cuff, a lateral hinge for linking the lateral portion of the thigh cuff to the lateral portion of the shank cuff, means to strap the thigh cuff to a wearer's thigh, and means to strap the shank cuff to a wearer's shank. The medial hinge, having a first variable axis of rotation, has a first pair of parallel, concentric spherical shells defining a first opening between them, fastened to the medial portion of the thigh cuff, and three rivets, forming a first equilateral triangle having a center coincident with the first variable axis of rotation, fastened to each shell. The medial hinge also has a first spherical shell designed to be inserted into the first opening, fastened to the medial portion of the shank cuff and three grooves to receive the three rivets. The lateral hinge, having a second variable axis of rotation, has a second pair of parallel, concentric spherical shells defining a second opening between the shells, fastened to the lateral portions of the thigh cuff, and three rivets, forming a second equilateral triangle having a center coincident with the second variable axis of rotation, fastened to each shell. The lateral hinge also has a second spherical shell designed to be inserted into the second opening, fastened to the lateral portion of the shank cuff and three grooves to receive the three rivets. The medial hinge and the lateral hinge have concavities opposite each other in order to account for the variable axis of rotation of the knee joint within the anatomical boundaries of the knee. In use, when the wearer's leg is extended, the first variable axis of rotation and the second variable axis of rotation are coincident and in alignment with the wearer's epicondyles, and when the wearer's leg flexes and extends, the first variable axis of rotation and the second axis of rotation are coincident throughout the range of motion, thereby accurately mimicking the instantaneous axis of rotation of the wearer's knee throughout flexion and extension, abduction and adduction and anterior/posterior translation. The improved knee orthosis is adjustable and has a slidable lower shin cuff to prevent migration of the orthosis along the wearer's leg.

Title: Process for bleaching chemical pulp for paper manufacturing
Inventor: FUKUSHIMA TAKAMASA
IPC: D21C9/10
Filed: 1996-09-20
Granted: 2005-04-26
Abstract: A process for bleaching chemical pulp for paper manufacturing comprising delignifying and bleaching chemical pulp which has been treated by cooking by simultaneous use of chlorine dioxide, a peroxide, and at least one reaction catalyst selected from the group consisting of oxoacids of elements of Groups IV, V and VI and salts of these acids.      Formation of organic chlorine compounds as by-products is suppressed by decreasing the amount of chlorine dioxide used in the ECF bleaching process in the first stage, and thus environmental toxicity in the waste water discharged from the bleaching process is decreased. Chemical pulp having a high degree of brightness is economically produced because increase in the production capacity is not required at all or suppressed to the minimum, and the investment cost is reduced to the minimum when the bleaching with chlorine in the first stage is converted into the bleaching with chlorine dioxide which is an ECF bleaching process.

Title: Production method of diffraction grating
Inventor: NISHII JUNJI
IPC: G02B6/124
Filed: 1996-11-13
Granted: 2004-10-12
Abstract: This invention provides a method of producing a diffraction grating of a spectroscope by applying light to a thin film of glass having characteristics such that a density change occurs with the change of a glass structure upon irradiation of light and volume expansion occurs irreversibly.      The method comprises applying light to a diffraction grating formation portion of a surface of the thin film by applying light through a phase mask or applying interference light, and causing the light irradiation portion of glass to expand and to thereby form the diffraction grating. Light to be applied is generally laser beams of ultraviolet rays, such as an excimer laser, a Nd-YAG laser or UV higher harmonics of a dye laser. A laser beam of a visible light region can be used, too. Preferably, a silica single crystal plate is used for the substrate of the thin film, and sputter vacuum deposition is used for forming the thin film. The glass composition whose volume expands upon irradiation of light is GeO2-SiO2 type glass having a GeO2 content of 20 to 95 mol%, but this composition is not particularly limitative, and any glass compositions can be used so long as they have a high volume expansion coefficient.

Granted: 2007-01-30
Abstract: A light sensitive dimmer switch circuit for controlling the illumination level of a light as a function of the ambient illumination level surrounding the dimmer switch circuit by selectively controlling an AC power signal provided to the light includes a photocell and a phase control circuit. The photocell is responsive to the ambient illumination level and has a conduction state associated therewith. The conduction state changes, in response to the ambient illumination level, such that the photocell effectively exhibits either a substantially open circuit or a substantially short circuit. The phase control circuit selectively varies a conduction phase angle associated with the AC power signal which correspondingly causes a variation in the illumination level of the light. The phase control circuit, in response to the photocell, selectively varies such conduction phase angle and thus the illumination level associated with the light when the photocell exhibits an open circuit and, conversely, prohibits the AC  power signal from being provided to the light when the photocell exhibits a short circuit. Preferably, the phase control circuit permits the light to illuminate approximately at a full illumination level while the photocell exhibits a short circuit. Thus, the light sensitive dimmer switch circuit controls the light such that a user may operate the same in either an off region, a dimming region or a full illumination region.
