Title: Tire charged with small sized spherical bodies capable of sufficiently resisting against deformation of load in outside tire having double structure
Inventor: KIMURA MAKOTO
IPC: B60C19/12
Filed: 1994-03-03
Abstract: PURPOSE:To prevent large deformation of a tire from being easily caused due to a puncture by filling the outside tire of a tire, having a double structure, with not air but spherical bodies in small size such as preventing a leak from a through hole even when it is caused in the outside tire. CONSTITUTION:The inside of an outside tire 5 of a tire having a double structure is charged with not air but spherical bodies 6 in small size such as preventing a leak from a through hole even when it is caused in the outside tire 5. When charged with only air, by causing the through hole, an internal pressure is decreased, thus to largely deform the tire, but by charging with this small sized spherical body 6, since it resists against large deformation of the tire, no large deformation of the tire is caused.

Abstract: PURPOSE:To quickly equalize a line distortion by providing a means preventing a correlation matrix from being singular when an inverse matrix of the correlation matrix of a reception signal string is calculated to minimize the sum of output error signals of an equalizer for a prescribed period. CONSTITUTION:The calculation of an inverse matrix calculation section 14 and a gain vector calculation section 16 is given respectively by equations I, II, where (n) is a white noise vector orthogonal to (y) and is generated by a reception section to satisfy the property of equation IV. A (2N+1)-th term longitudinal vector Kn is a Kalman gain vector at a time (n). The equations I, II are lemmas of inverse matrix of an input signal correlation matrix, and when an initial value matrix P0 is selected to be rhoI according to equation III, a (2N+1)X(2N+1) matrix Pn approaches an inverse matrix PHI<-1> of the input signal correlation matrix PHI as sequential revision. A correlation matrix PHI' is expressed in equation V, in which the inverse matrix is obtained by the action of a correlation matrix regularity section 12 resulting from the sum of (n) to the input signal string yn. Thus, even when a substantial matrix PHIis irregular, the matrix PHI' is always regular and the inverse matrix Pn is estimated stably.

Title: Method for measuring wavelength distribution in longitudinal direction of optical fiber
Inventor: HATAYAMA HITOSHI
IPC: G02B6/00
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To provide a method for measuring a wavelength dispersive distribution in the longitudinal direction of an optical fiber, capable of making a measurement error smaller without depending on the distance from a measuring end. SOLUTION: The first power level to be imparted from a measuring apparatus is a value not reaching the saturation level SS of an OTDR waveform. When measurements are made while increasing distance, the waveform power level decreases with the distance. An area in which the waveform power level decreases to a measurement limit power level SL at which a measurement error is not higher than a predetermined value is a measuring area 1, and at this position an attenuated value is changed to measure a measuring area 2, and this operation is repeated to measure the overall length of an optical fiber. Data about the measuring area at each attenuated value is corrected so that data before and after the switching position show the same value, so as to obtain longitudinally continuous data along the overall length of the optical fiber.

Abstract: PURPOSE:To withdraw automatically a tap for preventing a workpiece from breakage and improving the efficiency of operation by reversing the tap on the basis of the rotational frequency and feed speed stored during working when tapping is stopped by service interruption or the like and then resumed. CONSTITUTION:When working is interrupted during tapping and again resumed, a resumption starting signal is supplied to the input of a micro-computer 1 from a manual data input unit 4 or the like. The micro-computer 1 reads out the tapping data, i.e. whether or not the tapping is being done, the rotational frequency of a spindle and feed speed stored in a non-volatile memory 3. If during the tapping, a machine is set in the opposite rotational direction to the one of the spindle, which is determined by the rotational frequency, feed speed and tapping commanding code at that time stored in the memory 3. A tool is withdrawn from an input unit 4 by a certain distance, i.e. at least a distance corresponding to the length L of a tapping hole and returned to a specified position with quick feed. Thus, operations of resumption in the tapping are reduced, eliminating breakages of tool and workpiece.
