Abstract: PROBLEM TO BE SOLVED: To effectively detect abnormality in a device by sampling with specified period a regenerative output signal of a magnetic head and converting it into digital values corresponding to amplitude values of respective sampling points. SOLUTION: A processor 11 rotates a motor 13 through a motor control circuit 12, and moves the magnetic head 14 along a magnetic stripe at an optional fixed speed, thus to amplify 15 the output signal of the head 14 and store the A/D converted 16 and digitized data in a memory 17.

Filed: 1996-06-18
Abstract: PROBLEM TO BE SOLVED: To realize a detection means that improves stability at a low level and generates a detection output voltage capable of controlling an output level over a wide dynamic range with a simple circuit. SOLUTION: A 1st (2nd) detection section 4a(4b) of a detection means 11 has a diode 41a(41b) and detects a signal S3 distributed by a distribution section 3 to provide an output of a detection voltage Va(Vb). A forward bias Bv is applied to the diode 41a to improve the detection efficiency at a low level. Furthermore, in order to keep a detection efficiency of the 1st detection section 4a higher than the detection efficiency of the 2nd detection section 4b at all times, the resistance of resistors Ra, Rb of smoothing circuits of the 1st and 2nd detection sections 4a, 4b is selected to be Ra>Rb. A detection voltage synthesis section 5 calculates a difference of the absolute value between the detected voltages Va and Vb and provides an output of the result as a detection output voltage Vc.  In this case, since the polarity of the detection voltages is respectively positive for the Va and negative for the Vb, the detection voltages are added by using an operational amplifier.

Title: Liquid crystal display device
Inventor: OTA MASUYUKI
IPC: G02F1/1343
Filed: 1997-06-13
Abstract: PROBLEM TO BE SOLVED: To drive an electrode with a low voltage and a low power consumption and to provide a liquid crystal display device of good image quality by locating the confronting electrode on both side of adjacent pixels and specifying the width of the confronting electrode. SOLUTION: When the width of the electrode of a video signal line DL is determined by the productivity of yield, the width of the electrode of a confronting electrode CT adjacent to the video signal line DL is made to be larger than a half of the width of electrode of the signal line DL. This serves to absorb an electric flux line by the confronting electrodes on both sides and an electrode having the width wider than the same width is necessary for absorbing the electric flux line generated from a certain width of electrode. Consequently, since the electric flux line generated from a half of the electrode of the signal line DL is absorbed enough by the confronting electrode Ct on both sides, the width of the confronting electrode Ct adjacent to the signal line DL is made larger than a half. Consequently, cross talk affected by the influence of the video signal is prevented.

Abstract: PURPOSE:To enable fuel supply to be automatically controlled, while improving the stability of a reclaimed land and promoting loading and unloading efficiency by reducing pellet voids, by a method in which refuse plastic material is pulverized and heated, and then it is extruded by a mold into the sticklike column with a specified particle diameter and length. CONSTITUTION:Refuse plastic pellet P is composed of a sticklike almost columnar body of a diameter of 8-12mm and a length of 20-25mm. To obtain said pellet, refuse plastic is first crushed roughly, and after pulverizing it is press-worked by an extrusion molding machine. The pellet is obtained in a series of production processes of sorting, rough crushing, selecting, pulverizing and molding under heating. In the sorting process, only plastic refuse is sorted out from urban refuse and industrial waste matter and is collected, and in the roughly crushing process, refused plastic is crushed by a crusher of a vertical uniaxial swing hammer type, etc., and in the selecting process, only such refuse plastic that is fusible under heating is collected, and metallic refuse and wet refuse, for example, are taken off, and in the pulverizing process, roughly crushed plastic refuse is pulverized into further fine particles, e.g. into small particles of about 10mm diameter, and in the extrusion molding process, the pulverized plastic refuse is extrusion molded into the refused plastic pellet, by using a special heating extrusion molding machine.

Title: Measuring apparatus for bearing gap of vertical type rotary machine
Inventor: FURUKAWA YOSHIO
IPC: G01B21/00
Filed: 1979-12-05
Abstract: PURPOSE: To measure a bearing gap at the outside of an oil tank by measuring the displacement of a measurement reference ring.  
     CONSTITUTION: Measurement reference ring 14 is arranged over bearing boss 5 of the vertical type rotary machine and near its outer circumference. As the force due to the deformation of the trestle of the rotary machine operates on bearing boss 5, bearing boss 5 deforms asymmetrically and the gap of guide bearing shoe 1 varies. Measurement reference ring 14 is made large in rigidity and supported by reference- ring holder 15 of an elastic body, so that the force due to the deformation will not operate on measurement reference ring 14. Therefore, the bearing gap between guide bearing shoe 1 and rotating shaft 2 can be measured at the outside of the oil tank by measuring relative displacement variation in the radius direction between measurement reference ring 14 and holding member 16 by displacement gauge 17.

Title: Dc component deleting circuit
Inventor: NISHIO FUMITAKA
IPC: H03M3/02
Filed: 1992-06-16
Abstract: PURPOSE:To prevent the occurrence of noise tones and the distortions by performing the opposite phase addition between an input analog signal and the output obtained by integrating the bit stream signals undergone with the sigma-delta (SIGMADELTA) modulation through a resistor, extracting a DC component, and then adding the output of the DC component to the input analog signal through the resistor. CONSTITUTION:The digital outputs undergone the SIGMADELTA modulation are integrated by a resistor R2 of an integrating means and a capacitor C1. Thus an output is obtained and undergoes the adverse phase addition with the analog signal which does not undergo the obersampling, the SIGMADELTA modulation and the A/D conversion yet through a resistor R1 of a DC component extracting means, the resistor R2, a resistor R4, a capacitor C2, and an operational amplifier circuit 21. Then the output of the DC component is added to the analog signal by the resistors R5 and R6 of an adder means. Thus it is possible to prevent the occurrence of noise tones and distortions due to the characteristic fluctuation of a D/A converter and to prevent the generation of the feedback voltage even if the input cycle is increased and the MSB is kept at 1 or 0 for a long period as long as no DC component exists.
