Title: Digital filter device and its filtering method
Inventor: MAJANI ERIC
IPC: H04N1/41
Filed: 1999-06-22
Abstract: PROBLEM TO BE SOLVED: To provide a digital filter device and the filtering method for converting one input digital signal into two output digital signals. SOLUTION: An input sample (xi) is contained in an input digital signal, and an output sample (y2i+1) formed of an odd order is contained in a first output digital signal. The respective samples are equal to values obtained by subtracting the approximate value of the total of input samples in a (pk) even order, which are obtained by multiplying first filter coefficients, from the same order input sample (x2i). An output sample (y2i), formed of the even order, is contained in a second output digital signal. The respective samples are equal to values obtained, by subtracting the approximate value of the total of the output samples formed of an (Uk) odd order, which are obtained by multiplying the second filter coefficients, from the input sample (x2i) of the same order.  A second filter coefficient (Uk) is selected from among following coefficients, namely, [5/16, 5/16], [-1/16, 5/16, 5/16, -1/16] and [1/256, -15/256, 78/256, 78/256, -15/256, 1/256].

Title: Detecting device for defect
Inventor: FUJIWARA KATSUMI
IPC: G01N21/956
Filed: 1989-07-06
Abstract: PURPOSE:To detect a defect of a tube body which can not be detected directly by an optical means by reflecting light leaking out of the opening part of the tube body by a hemi-elliptic mirror and a hemispherical mirror and making the light incident on a photodetecting means as an approximate parallel light beam. CONSTITUTION:A printed board 10 is irradiated with light 12 and the light 13 leaking out of the opening part 11b of the tubular plated film (tube body) 11 is reflected by the reflecting surface 14a of the hemi-elliptic mirror 14 arranged so that its focus 14b is aligned with the opening part 11b to travel toward the other focus 14d of the mirror 14. The hemispherical mirror 15 is arranged at the focus 14d, so the light 13 is reflected by the reflecting surface 15b of the mirror 15 to become the approximate parallel light beam 13', which passes through the opening part 14f of the mirror 14 and is made incident on a convex lens 16a. The lens 16a converges the light beam 13' to form its image on the photodetection surface of a photodetecting element 16b. The element 16b converts the light beam 13' into a current value proportional to its intensity and outputs the current value to an ammeter. When the value of the current flowing to the ammeter is larger (smaller) than a predetermined value, it is decided that the plating film 11 has (does not have) a defect 11c.

Title: Continuous annealing method for thin steel strip
Inventor: HORI SEIKI
IPC: C21D9/56
Filed: 1987-07-15
Abstract: PURPOSE:To efficiently anneal a thin steel sheet without oxidizing the sheet by heating a thin steel strip in a low temp. range and high temp. range respectively by direct fire reduction heating and laser beam, etc. at the time of subjecting said strip to continuous annealing. CONSTITUTION:The long-sized thin steel strip is annealed by the direct fire reduction heating method of <=1.0 air ratio while the oxidation of the thin steel strip is prevented in the low temp. range of <=650 deg.C at the time of subjecting the thin steel strip to the continuous annealing. The high temp. oxidation by CO2 and H2O is generated even by the direct fire heating of <=1.0 air ratio if the temp. exceeds 650 deg.C and, therefore, the heating and annealing in the high temp. range above 650 deg.C are executed by a CO2 laser or electron beam. The cooling of the thin steel sheet after the annealing treatment is executed between the final hearth roll passes of the heating by a liquid cooling, gas jet cooling, roll cooling or wet air cooling method, by which the annealing of the thin steel in an extremely short period of time is enabled without damaging the material quality of the thin steel sheet.

Patent JP-S5967435-A (JP)
Title: External force detecting circuit
Inventor: HARIKI KAZUO
IPC: H02P7/00
Filed: 1982-10-12
Abstract: PURPOSE:To enable the detection of a torque less than required by an ordinary motor by applying an output of a tachogenerator to the input of an comparator for checking to ensure that the motor current detected exceeds the given set value through a phase advancing circuit. CONSTITUTION:A phase advancing circuit comprising an arithmetic amplifier 1, a resistance 5 and a capacitor 6 is added to a motor overcurrent detection circuit to subtract a differentiated value of the tachogenerator output from a motor current whereby a motor current value alone can be detected. Since there is no actual acceleration, this enables the identification of any external force thereby allowing immediate actuation of immergency stop. Here, the detection can be done with a torque level by far less than required for the normal operation of the motor thereby guaranteeing the safety of a human body.

Abstract: PURPOSE:To efficiently heat a whole building even if it has a side wall surface which is interrupted from solar radiation, by a method wherein the lower parts of a roof ventilating clearance and a space under a floor are interconnected through a duct, and when a rising air stream is created in the roof ventilating clearance, the air under the floor is bled, and the hot air, present in a garret, is forced to fall through cavities in an inner wall to the space under the floor which is forced into negative pressure condition resulting from bleeding of the air. CONSTITUTION:A ventilating clearance A1 is formed between a roofing material 1 and a heat insulation material 2, and the lower parts of the roof ventilaing clearance are communicated with a space 6 under a floor through a duct 5. In such building, when solar radiation is collected by a roof surface, a rising air stream is created in the ventilating clearance A1 to bleed the air in a space 6 under a floor through a duct 5. The space 6 under the floor is forced into negative pressure condition resulting from bleeding of the air through the duct 5, and the amount of the air, equivalent to that of the bled air, falls through cavities 7 in an inner wall. In which case, the hot air in a space 3 in a garret falls to distribute the heat to a whole building.
