Title: Method for locating ground fault section of wire shield power cable
Inventor: OUCHI KEIICHI
IPC: G01R31/08
Filed: 1989-11-27
Abstract: PURPOSE:To locate a fault section by measuring currents at two places on S- and Z-twist parts from the outside of a cable and calculating only a cable conductor current from the vector sum of the measured currents while calculating only a shield current of the vector difference thereof. CONSTITUTION:The current observed in the center part of an S-twist part is the sum I0+IIS of the vector I0 of a cable conductor current and the vector IIS of a shield current and the current observed in the center of a Z-twist part is the sum I0+IIZ of the vector I0 of the cable conductor current and the vector IIZ of the shield current. The component in the circumferencial direction of the current (I0+IIS) in the center of the S-twist part is IISsintheta+I0sin(180 deg.+delta)=IISsintheta-I0sindelta and the component in the circumferential direction of the current in the center of the Z-twist part is IIZsin (360 deg.-theta)+I0sin(180 deg.+delta)=-IIZsintheta-I0sindelta. Therefore, the sum of the vectors of the components in the circumferential direction corresponds to the difference IIS-IIZ between the vectors (I0+IIS), (I0+IIZ). By this method, since the signals corresponding only to the cable conductor current and the shield current are obtained, it can be judged in which spans a ground fault section exists even for a section containing a common joint.

Title: Valve seat surface inspection instrument method
Inventor: MORI SHIGERU
IPC: G01N21/88
Filed: 1999-10-28
Abstract: PROBLEM TO BE SOLVED: To provide a technique, capable of correctly measuring a cross-sectional shape even with an arrangement to irradiate the cylinder head surface with slit light at an angle, in cylinder head surface inspections through the use of a light-section method. SOLUTION: A valve seat surface is irradiated with a slit light at an angle by a sensor head 10 to visually recognize the image of a light-section line. A slit light source is rotated relative to the center of the valve seat as the axis of rotation, and the visually recognized image is converted into sequence-of- point data by a control part 60, and the nonlinearly distorted sequence-of-point data is further corrected. As a result, it is possible to measure the thickness of an overlaying layer and to predict the presence or absence of underfills, etc., by comparison measurements with the measured values of a master work.

Abstract: PROBLEM TO BE SOLVED: To provide a gathering device capable of easily and optimally setting a gathering interval even if there are changes of the conditions on a gathering device side such as gathering speed and number of sheet feed stages in use and those on a post-treatment device side such as sheet sorting time and gathered matter feed speed. SOLUTION: A detector 12 for detecting the passage of matter to be gathered is arranged in a feed route for the matter to be gathered formed by a gathering device at a proper location, an empty time for the matter to be gathered passing the detector 12 is obtained by a calculation means 10, and a difference between the time thus obtained and a post-treatment time is compensated by deducting a gathering treatment time obtained beforehand by a gathering interval calculation means 9 using the number of sheet feed stages, sheet overlapping degree, and feed speed from a gathering interval obtained using a post-treatment time for the matter to be gathered and allowance time. Also the compensatedly deducted time is re-set in a gathering interval setter 1, and the subsequent gathering is performed for each compensated gathering interval.  Thus a burden on an operator to adjust the gathering interval to an optimum value is reduced, and also the gathering interval can be set easily to the optimum value.

Inventor: EGGLETON BENJAMIN JOHN
IPC: H04B10/29
Filed: 1999-10-29
Abstract: PROBLEM TO BE SOLVED: To obtain an optical diffraction grating device having an adjustable chirp. SOLUTION: The optical waveguide diffraction grating having an adjustable chirp includes a waveguide diffraction grating thermally brought into contact with an electrically controllable heat converting substrate whose temperature is changed along the length of the diffraction grating (A).

Abstract: PURPOSE:To operate an inverse trigonometric function arctan(chi) at high speed by inputting a value 1/H<2>+1 and a low-order digit L in a memory to a multiplier, and adding the output value of the multiplier on a value arctan(H) by an adder. CONSTITUTION:The value (chi) is divided into a high-order digit H and the low- order digit L by every (n) digits. Then, in equation I, the arctan(chi) can be obtained by one time of multiplication and that of addition by preparing a table ROM 12 which inputs H and outputs the value arctan(H) and the value 1/H<2>+1. Since it is H<1 and L<2<-n>, (n) digits are enough for the arithmetic accuracy of a second item in equation I. To obtain accuracy of 2n digits in the arctan (chi), it is necessary to provide an arctan(H) table of 2n digits X2<n> words, a 1/H<2>+1 table of (n)digits X 2 words, and the multiplier 14 which performs the multiplication of the output(n) digits of the 1/H<2>+1 table by (n) digits of L, and the adder 16 which adds the high-order (n) digits of a multiplication result on the output 2n digits of the arctan(H) table. In such a way, it is possible to operate the arctan(chi) at high speed.

Filed: 1990-11-15
Abstract: PURPOSE:To reduce errors in the case of encoding a voice in which vector quantization is used and to improve voice recognition rate by using two kinds of code books for man and for woman. CONSTITUTION:The voice of a speaker is converted into a digital signal in an input part and a characteristic parameter is extracted by an extraction part. Furthermore, it is analyzed by Fourier transformation, etc., to detect the pitch of the inputted voice.

The characteristic parameter extracted is vector- quantized by the use of the code book and encoded to be any of 256 codes. The voice data encoded in an encoding part is recognized as a word and a sentence in a recognition decision part. Thus, the errors in the case of encoding the voice in which the vector quantization is used are reduced and the voice recognition rate is improved.
