Title: Method for preventing buckling of hot rolled sheet in sheet treatment line
Inventor: SAWADA MAMORU
IPC: B21C47/16
Filed: 1995-09-07
Abstract: PROBLEM TO BE SOLVED: To reduce the running cost by measuring the flatness of the steel strip before being subjected to the plastic deformation in un-coiling, and taking a measures to prevent fluting only to the steel strip in which the steepness exceeds the prescribed value. SOLUTION: A hot rolled coil 1 is un-coiled by an un-coiler 2. A steel strip 3 of the coil 1 passes through a pinch roll 4, a leveler 5, and a shear 6. The flatness of the steel strip 3 after being un-coiled from the coil 1 and before entering the pinch roll 4 is measured by a flatness measuring device 12. Only when the flatness of the steel strip 3 exceeds 1%, a control valve 10 is opened through a control device 11, and cooling water is injected from a nozzle 9 to cool the coil 1. Since the fluting generation ratio is rapidly increased when the flatness exceeds 1%, only the steel strip whose flatness exceeds 1% is cooled. The running cost is reduced because no fluting preventive measures is taken to every coil.

Abstract: PROBLEM TO BE SOLVED: To obtain a dielectric thin film improved in its electric characteristics through the MOCVD technique by using high-purity Sr and/or Ba complexes as a source of M metal in the production of a dielectric thin film of the crystalline structure of the formula: MTiO3 . SOLUTION: This invention provides a process for producing a dielectric thin film of the perovskite crystalline structure of the general formula: MTiO3 (M=Ba and/or Sr) through the organo-metal chemical vapor deposition(MOCVD) technique using Sr or Ba β-diketone complex or both of formulas I and II (M=Sr or Ba) whose content of other impure metals is <1ppm as a metal source. This complex is produced by allowing high purity metallic Sr or Ba to react with a β-diketone in a non-aqueous organic solvent or by mixing high- purity SrO or BaO with aluminum and reducing the oxide with heat under reduced pressure.

IPC: B65H3/06
Filed: 1992-08-31
Abstract: PURPOSE:To aim at simplification of a shutter mechanism of an automatic paper feeding mechanism and reduction of its manufacturing cost. CONSTITUTION:An input hub 12 fixed to a paper feeding roller rotation shaft 4 rotates together with the rotation of the paper feeding roller rotation shaft 4, and an output hub 11 initiates rotation by virtue of a spring clutch unit 7 containing a torsion coil spring 13 causing a frame 6 fitted to the output hub 11 to ascend.

IPC: G09F9/33
Filed: 1994-08-31
Abstract: PURPOSE: To make it possible to impart directivity to the light rays emitted from respective through-holes and to make bright and distinct display with good visibility in a practicable visual observing position by arranging a translucent lens aggregating plate formed of many convex lenses in superposition on a mask plate. CONSTITUTION: The mask plate 3 and the lens aggregating plate 4 are disposed in superposition on a display substrate 2. This lens aggregating plate 4 is formed with the many microconvex lens parts 4a on the front surface of a resin plate which allows the transmission of light. These convex lens parts 4a are formed by projecting the many circular regions set longitudinally and transversely on the front surface of the lens aggregating plate 4 respectively to the same shape of nearly the hemispherical shape. The directing characteristic of such lens aggregating plate 4 is regulated by fitting relations between the thickness of the mask plate 3 and the aperture diameter, etc., of the through-holes 3a thereof and the refractive indices of the light of the lens aggregating plate 4 itself, the curvature of the hemispherical shapes of the convex lens parts 3, etc.  The spacings for forming the respective convex lens parts 4a must be so set that the lens diameter of the circular convex lens parts 4 is below l/5 the aperture diameter of the through-holes 3a.

Title: Photoelectric switch
Inventor: FUKUDA MASAHIKO
IPC: H03K17/78
Filed: 1985-10-16
Abstract: PURPOSE:To prevent malfunction by forecasting it before an incident light pulse and an irradiated light pulse are overlapped when the period of the incident light pulse signal is longer than the period of the irradiated light pulse so as to neglect a noise light incident next. CONSTITUTION:A projecting section 3 generates a projected light beam in response to the irradiated light pulse having a prescribed period formed by a frequency divider 2. A light receiving section 4 converts the received signal into the incident light pulse signal and gives the result to a gate circuit 10 and a gate control circuit 5. The gate circuit 10 uses an irradiated light pulse so as to gate the incident light pulse signal from the light receiving section 4, and the gate control circuit 5 forecasts it before the incident light pulse and the irradiated light pulse are overlapped when the period of the incident light pulse signal is longer than the period of the irradiated light pulse to form a gate signal comprising pulses of the period being a natural number of multiple of the period of the irradiated light pulse thereby closing the gate of the gate circuit 10. Thus, the incident light noise having the period longer than the period of the irradiated light is prevented.

Filed: 1992-08-31
Abstract: PURPOSE:To easily separate polarization layers from a difference of polarization planes and to operate a high density recording by providing the polarization layers so that the rotation directions of the polarization planes are alternately different at adjacent tracks. CONSTITUTION:The reflected lights of tracks R1 to R3 are reflected by a beam splitter 22 in a mixed condition, led to a first polarizing plate 25, but, when only a first polarization whose plane is rotated in a clockwise direction toward a drawing is transmitted by the first polarizing plate 25, only the reflected lights from the tracks R1 and R2 are transmitted, the other lights are reflected and led to a second polarizing plate 27. No crosstalk components from the tracks R1 and R3 are included in a second reproducing signal S2 being a reproducing signal from a second light receiving element 28 and thus, even when a highly dense recording is operated, information only from a desired track R2 is accurately reproduced.
