Title: Periodically arranged magnetic body detector
Inventor: IWATA TETSUKI
IPC: G01M99/00
Filed: 1993-05-25
Abstract: PURPOSE:To allow detection at a position spaced apart from an object with no external influence by matching the outline of a group of detection coils functioning as the inductance of an LC oscillation circuit with the outline of a magnetic body to be detected projected onto the moving face of a transfer system. CONSTITUTION:A transfer system 10 transfers a magnetic body to be detected. Each coil 52a of a group of detection coils 52 in a periodically arranged magnetic body detector is arranged at an appropriate position of the system 10 such that the positional relationship with the magnetic body can be varied. The group of coils 52 functions as the inductance of an LC oscillation circuit 54. The coils 52a constituting the coil group 52 are connected in series, in parallel, or in combination with the circuit 54. Output from the circuit 54 is fed to a frequency variation deciding circuit 56 comprising a frequency counter in order to detect the presence or the position of the magnetic body.

Filed: 1982-08-23
Abstract: PURPOSE:To prevent an anamorphic lens made of plastic material from varying in performance with abmient temperature by equipping the 1st image-formation optical system with a cylindrical lens which is made of plastic material and has a negative refracting power. CONSTITUTION:Luminous flux L emitted from a light source device 1 is reflected by the reflecting surface 3a of a deflector 3 after passing through a linear image optical system 2, and the reflected luminous flux L is deflected according to the turning of the deflector to form an image of a medium 5 to be scanned through the anamorphic lens 4 having a toric surface. The anamorphic lens 4 is made of the plastic material and shifts in its image formation position in a plane of deflection according to temperature, but the variation is canceled by the 1st cylindrical lens 2a which is made of the plastic material and has the negative refracting power, thereby maintaining the image formation position near the medium 5 to be scanned.

IPC: C22C1/04
Filed: 1980-10-22
Abstract: PURPOSE:To obtain a permanent magnet having a desirable shape without reducing remarkably a magnetic characteristic by a method wherein a magnetic arrisotrapy is provided for a Mn-Al system magnet through a cold or a hot plastic working process, the foregoing magnet is smashed to pieces in liquid nitrogen and a resin molding is provided for the magnet in an intensive magnetic field. CONSTITUTION:When a Mn-Al system magnet having an easily magnetized axis along a longitudinal direction, which is worked through a hot extruding process by cold swaging or at 600-700 deg.C approximately, and which is crushed at a normal temperature, the undesirable influences like distortion, twin or the like are left in the magnet powder. As a result, a magnetic flux density is considerably lowered if the resin molding may be performed in the magnetic field. If the crushing may be performed in liquid nitrogen (-169 deg.C), the defects are not remarkably introduced to the magnetic powder. On the other hand, if the resin molding is performed in the intensive magnetic field, a remarkable reduction of the magnetic flux density can be prevented and a permanent magnet having a desirable shape be obtained. According to the above constitution, because the metallic material becomes brittle in a low temperature and becomes easy to be crushed with a low energy, and further because a working distortion is not introduced and a moving of the atoms becomes difficult, any abnormal condition is not occured easily.

Title: Optical magnetic field sensor
Inventor: KAJIOKA HIROSHI
IPC: G02B6/024
Filed: 1983-08-10
Abstract: PURPOSE:To widen a dynamic range with high sensitivity and high accuracy, by detecting magnetic flux by using a polarization plane maintaining optical fiber. CONSTITUTION:Beam from a light source 1 is subjected to linear polarization by a polarizer 2 and incident on a polarization plane maintaining optical fiber 5 while transmitted by a beam splitter 3. Emitted beam from the polarization plane maintaining optical fiber 5 reaches a condensing lens 9 through a collimating lens 46. On the other hand, reflected beam from the splitter 3 directly reaches the lens 9. Therefore, interference of two beams is generated in the splitter 3 but the matching of the plane of polarization is taken and the emitting side of the fiber 5 is offset so as not to overlap two beams to obtain Young interference fringe. The interference beam condensed by the lens 9 passes a charge coupled device array 10 and a calculation processing part 11 to send out output corresponding to a magnetic field. By this mechanism, a dynamic range can be widened with high sensitivity and high accuracy.

Title: Pulse dropout detecting circuit
Inventor: FUJIHIRA YASUO
IPC: H03K5/19
Filed: 1980-10-22
Abstract: PURPOSE:To obtain an accurate pulse dropout detecting circuit, by constituting this circuit only with a delay circuit and a digital circuit. CONSTITUTION:An input pulse P is delayed into a pulse P2, which has a delay time T1 about 1.5 times as long as the period of the pulse P, by a delay circuit D1. Meanwhile, a flip-flop F1 is inverted in accordance with the pulse P to output a square wave P1 of 50% duty ratio. This output is delayed in a delay circuit D2 by a delay time T2 to become a pulse P3, and exclusive OR between the pulse P3 and the pulse P1 is operated by an exclusive OR circuit V to obtain a pulse P4. The pulse P4 is sampled and held at the timing of the pulse P2 by a flip-flop F2. In this case, since the delay time T1 is set to a time about 1.5 times as long as the period of the pulse P, the malfunction is prevented. After an error output is issued once, a gate G stops the input of the pulse P2 to hold the result.
