Abstract: PURPOSE:To detect an azimuth with high accuracy, by feeding back the outputs of two magnetic sensors crossing each other at right angles to two coils crossing each other at right angles inclusive of the magnetic sensors through an operation part to always hold the magnetic sensors in a zero magnetic field. CONSTITUTION:The component forces of geomagnetism in X- and Y-directions are detected by two magnetic sensors 60, 61 crossing each other at right angles to be inputted to an arithmetic unit 30. Coils 5, 4 having coil surfaces crossing each other at right angles inclusive of the magnetic sensors 60, 61 are provided. The arithmetic unit 30 operates the inputs from the magnetic sensors 60, 61 to input a feedback signal to two coils 5, 4 so as to cancel geomagnetism. By this method, the magnetic sensor 60, 61 are always held in a zero magnetic field and highly accurate azimuth output is obtained.

Title: Acoustic diagnosis abnormality detecting device
Inventor: KIKUCHI YOSHIHIRO
IPC: G01N29/12
Filed: 1978-04-14
Abstract: PURPOSE: To present a simple, secure device, by coupling a wave director bar to the constituent elements i a vessel, detecting only the surface wave having the smallest energy damping of the acoustic signals, and improving the S/N ratio and decreasing the number of acoustic detection systems.  
     CONSTITUTION: Acoustic signals of abnormal phenomena taking place in the constituent elements in a vessel are detected as surface waves in the pickup part, which propagate through a main wave director bar 5 to reach an acoustic detecting part 6. In the detecting part 6, the acoustic signals propagated through the bar 5, the signals detected in a main acoustic detector part 15a, and the signals detected in a sub acoustic detector part 15b through a sub wave director bar 16 disposed in a vessel construction member 1 are judged if they exceed the threshold value set by the both outputs obtained by way of a preamplifier 17. Only when the signal propagated through the construction member 1 is received in both detector parts, a noise removal device 18 outputs 1, and the signal when 0 is outputted is regarded as a signal from the bar 5, thereby removing the effect of noise. Thus, the signals propagated from the bar 5 may be picked up at high S/N ratio.

Filed: 1985-03-08
Abstract: PURPOSE:To obtain a high-performance zoom lens by arranging a plastic lens which has one aspherical surface with extremely low refracting power nearby at least either of the 4th and the 5th lens components among five lens components. CONSTITUTION:The zoom lens consists of the five lens components; the 1st lens component has three-element constitution and positive refracting power, the 2nd lens component has three-element constitution and negative refracting power, and the 3rd and the 4th lens components both have one-group, one- element constitution and negative and positive refracting power respectively. The plastic lens which has almost no refracting power is arranged nearby either of the 4th and the 5th lens component and at least one surface of the plastic lens is made aspherical. This plastic aspherical surface lens compensates a spherical aberration and the refracting power of the plastic lens is reduced to suppress aberration variation due to temperature variation and humidity variation. Consequently, aberrations are compensated excellently with good balance to obtain the zoom lens of a X6 large power variation ratio and an about F number 1.

Filed: 1996-03-01
Abstract: PROBLEM TO BE SOLVED: To reduce an influence of bound, and execute excellent accurate measurement up to an idle range, in a fuel injection valve for gaseous fuel. SOLUTION: A valve 103 is brought in contact with a valve seat 110, and also attached to a plunger 102 through a rod 105. The plunger 102 is sucked by electromagnetic force generated from a coil 101 so as to form a clearance between the valve 103 and the valve seat 110, and fuel gas is ejected from this clearance. A flange 105A is formed in the center of the rod 105, and when the plunger 102 is sucked by a core 113, a stopper 106 is engaged with the flange 105A so as to regulate the movement of the rod 105. Hereupon, a check valve 117 is arranged in the plunger 102, thereby, when the check valve 117 is opened, the valve 103 is slowly opened, and when the check valve 117 is closed, the valve 103 is pushed to the valve seat 110, so that an influence of bound can be reduced.

Title: Method for breaking grain boundary of metallic material
Inventor: UEMORI RIYUUJI
IPC: G01N37/00
Filed: 1995-03-03
Abstract: PURPOSE: To break a grain boundary irrespective of the kind and the strength of a material by a method wherein an electric field is generated between a tip of a needle sample and an opposed electrode and a crystal grain boundary disposed on the tip of the needle sample is broken to expose a face of the grain boundary. CONSTITUTION: When, for example, a plus voltage not less than 0.1 KV is applied for a short time not longer than 1 second to a needle sample of which radius of curvature is not greater than 1μm by means of a field ion microscope, a crystal grain on a tip portion of the sample is taken off owing to electric field stress generated on the tip portion so that the sample is broken. By utilizing this technology, it is possible to break the grain boundary irrespective of a level of the strength of a practical steel in terms of the practical steel of which strength is roughly at most a half of an ideal one.  That is, the crystal grain on the tip portion of the needle sample is taken off owing to action of strong electric field stress that has not been utilized heretofore so that a face of the grain boundary is exposed on the tip of the needle sample without damaging a face of a grain boundary opposing to a crystal grain existing next in the depth direction. Thereby, it is possible to perfectly expose grain boundary broken face irrespective of the kind of the metallic material.

Abstract: PURPOSE:To prevent vapor or the like of magnetic fluid from intrusion to the vacuum side and pollution by providing a tapered yoke while providing a cylindrical body having the inner peripheral surface sufficiently approaching a movable shaft and further an exhaust hole for evacuating a space in a seal section. CONSTITUTION:Magnetic fluid 5 held normally between a movable shaft 4 and a yoke 8 by a magnetic field from a permanent magnet 2 is attracted toward an end of the yoke in which a gap between the yoke and the shaft is smaller, i.e. a smaller diameter portion according to the gradient of magnetic flux density formed by the tapered yoke 8 though it moves as the movable shaft 4 carries out straight line motion. Also, through an exhaust port 11 in the neigh borhood of the vacuum sideI of a space III formed by this movable shaft 4 and the tapered yoke 8 is evacuated the space III by another exhaust device 12 different from a main exhaust system at the vacuum sideI. Thus, even if vapor of the magnetic fluid 5 is generated by the straight line motion of the movable shaft 4, it is exhausted by the exhaust port 11 and the exhaust device 12 without polluting the interior of the vacuum sideI.
