Title: Correlation type speedometer
Inventor: MATSUSHITA SHIGETADA
IPC: G01P3/80
Filed: 1981-01-27
Abstract: PURPOSE:To prevent unsable operation due to spike-like noises or so by a construction wherein an integration circuit is interposed in either one of two input terminals of a correlation type speedometer which measures a speed of the measured object based on the correlated maximum values of two signals from the measured object detected at two separate locations. CONSTITUTION:A speed of the measured object is determined on the basis of the correlated maximum values of signals e1(t), e2(t) from the measured object detected at two separate locations spaced by a given distance. An integrator 6 is provided in either one of input terminals for those two signals. A signal e'1(t) is integrated by the integrator 6 and then fed to a delay element 1, while a signal e'2(t) is directly fed to a multiplier 3. In such a manner, the correlation type speedometer includes an integrator in one input terminal for the input signal so as to eliminate spike-like noises included in the input signals and an influence of high frequency components having no relation with the correlation. As a result, the correlated maximum values of the two input signals are automatically traced in a stable and accurate manner, so that the precise speed measurement may be performed based on the correlation therebetween.

Title: Reflection wave damping wall
Inventor: ISHIKAWA TOSHIYUKI
IPC: E04H9/14
Filed: 1991-01-30
Abstract: PURPOSE:To make lightweight, to reduce a cost and, at the same time, to promote execution efficiency by using wave reflection materials to form a wall surface of repeated regular recesses. CONSTITUTION:Wave reflection materials 1 such as glass, metal plate. ALC, conductive film, metallic mesh and, etc., are used to form a wall surface of repeated regular recesses on the surface of a structural skeleton section 2. The recesses are constituted of vertical or horizontal wave forms or inverted pyramids. Accordingly, external waves A and B are reflected from the wave reflection materials 1 of the wall surface and are synthesized at a point AB on the front line K of the center of the recesses. At that time, when propagation distances from the external waves A and B to the wave source are equal, in the case phases are reversed, they are synthesized at the a AB to become 0. According to the constitution, reflection waves can be reduced without using wave absorption materials.

Title: Method for recording optical disk
Inventor: HASHIMOTO YASUNOBU
IPC: G11B7/0045
Filed: 1988-01-20
Abstract: PURPOSE:To reduce the load of laser power by making the power for recording information constant in the long hole recording that employs constant angular speed recording system and recording information by varying the duty factor. CONSTITUTION:The increase of the rotational speed of an optical disk on/from which information is recorded/reproduced by means of long hole recording in which a system (CAV system) with constant rotational speed is employed, is represented by the increase of duty factor, accordingly, the increase of recording power can be made mild rather than sharp, hence the load of laser can be decreased. Also, fine variation in recording power can be easily achieved, and variation in the rotational speed can easily be coped with even when both recording power and duty factor are changed.

Abstract: PROBLEM TO BE SOLVED: To provide a clean sucking body excellent in strength and having satisfactory maintenance property by providing a handle so that a suction port cover can be fixed to a suction body, and curving the fitting part of an upper case to the suction port cover on a rotating cleaner body side. SOLUTION: A pair of horizontally sliding opening and closing levers 113 are set on the inside of a suction port cover 107, and they are operated, whereby the suction port cover 107 can be attached to and detached from a suction port body 108, An upper case 110 has a form partially curved on the suction port cover 107 side, and a groove part 114 is formed along it. Since a rib 115 having the same curved shape is set on the suction port cover 107 so as to be fitted to the groove part 114, the fitting part 116 has a curved form. The suction port cover 107 is stronger than a linear suction port cover, and the camber in molding of the suction port cover 107 is minimized. Since the clearance of the fitting part 116 is minute, the leak of the air flow sucked from the cleaner body can be reduced to improve the sucking performance.

Title: Method for identification of single phase-to-ground fault in high-voltage power transmission lines
Inventor: DOLGICERS ALEKSANDRS
IPC: H02H7/26
Filed: 2016-12-23
Abstract: The invention pertains to the field of electric power engineering and can be used for creating new fault location devices taking into account that usage of known fault location methods for short-circuit distance determination causes errors in case of large line power flows in pre-fault regime. The proposed method determines unknown parameters both for the pre-fault and fault regimes. Measurements of the instantaneous current and voltage signals for the monitored line and another line from the same substation are made, converted analogue-to-digital form and processed with random noise filters using orthogonal and symmetrical component filters. Measurements are performed and processed separately for the pre-faut and short-circuit regimes. Determination of the unknown parameters for both regimes is done by optimization of objective function, i.e., by minimization of the difference between the measurement and model output currents and voltages. The identified parameters of the load regime are fed into the short-circuit regime model, facilitating the identification of the short-circuit regime parameters. Upon the identification of the unknown short-circuit regime parameters, the short-circuit distance and the fault resistance are output to the interface.
