Title: Manufacture of resin-combined type magnet composed of rare-earth metal and cobalt
Inventor: SAKATA MASAAKI
IPC: H01F41/02
Filed: 1987-03-05
Abstract: PURPOSE:To manufacture a resin-coupled type magnet, with good productivity, whose magnetic performance is high by a method wherein, after a magnet composition consisting of magnetic particles composed of a rare-earth metal and cobalt and consisting of a thermoplastic resin have been mixed and kneaded, the compound is magnetized in a high magnetic field and, after that, said mixed and kneaded material is extrusion-molded while the magnetic field is being impressed. CONSTITUTION:After magnet powder of an intermetallic compound mainly composed of a rare-earth metal, cobalt and iron and a thermoplastic resin have been mixed and kneaded sufficiently by using a mixer, this compound is granulated. This granulated magnet composition is magnetized in a magnetic field which is higher than a molding magnetic field by using a direct-current electromagnet or a pulsed magnetizer. Small particles of a magnetized magnet composition 8 are put into an extrusion- molding machine and heated inside a cylinder 2 so as to be transformed into a fluid state. Then, they are fed into a metal mold by means of a screw 3. The magnet composition injected into the metal mold is molded in such a way that the magnet powder are oriented while they pass through a metal mold 5 on which the magnetic field has been impressed.

Abstract: PURPOSE:To enable accurate detection of the maximum value and the minimum value by inputting a D/A conversion output of an A/D conversion data and an input signal into an A/D converter through a differentiation amplifier to compute the current value from the conversion output thereof. CONSTITUTION:Initially, a control computation circuit 26 controls switching circuits 21 and 24 to input an input signal direct into an A/D converter 22, an output of which is memorized. Then, the control computation circuit 26 inputs an input signal and an output of a high-resolution D/A converter 25 into a differentiation amplifier 23 and an output with the difference amplified by 2<8> times inputted into an A/D converter 22. Then, the control computation circuit 26 reads the current data to compute the current value using a memory data and compares data from the results of the computation with the previous maximum data. When it is larger than the data, the maximum data is updated by data from the results of the computation and held while a signal is outputted to an alarm 27. This enables an accurate detection of the maximum and minimum values even with a low-resolution A/D converter.

IPC: G02F1/13
Filed: 1987-03-06
Abstract: PURPOSE:To prevent the generation of a rainbow-like diffracted image, by constituting the titled element so that width in the normal direction of a grating line in a diffraction grating part is made incident on about the center of the diffraction grating part, the diffracted light is brought to a total reflection by the surface on which the diffraction grating part is not formed, and thereafter, it is set to length which is not made incident again on other area of the diffraction grating part. CONSTITUTION:An incident light 5 which is made incident on a diffraction grating part 2a of a diffraction grating 2 is brought to an optical modulation by a refractive index difference of a liquid crystal 1 and the diffraction grating 2, and in the surface being orthogonal to the grating line direction of the diffraction grating 2, a diffracted light of plural orders is generated. IN such a state, with respect to width in the normal direction of a grating line in the diffraction grating part 2a, supposing that an incident light 5 is made incident on about the center of the diffraction grating part 2a, said width is set so that the diffracted light in this case is brought to a total reflection by other surface on which the diffraction grating part 2a is not formed, for instance, the surface which comes into contact with air of a transparent substrate 4, and thereafter, it becomes length which is not made incident again on other area of the diffraction grating part 2a. In such a way, the generation of a rainbow-like diffracted image from the diffraction grating part 2a can be prevented.

Filed: 1985-03-15
Abstract: PURPOSE:To expand dynamic ranges by connecting two sets of complementary pair circuits in parallel with each power supply and allowing each complementary pair circuit to control the direction of current and the current value to a drice coil. CONSTITUTION:A potential difference 2V between a +V and a -V potential is applied betweeen complementary pair circuits 9, 10, the drive coil 3 is controlled for each current direction as a power supply having a potential difference 2V in opposite direction to each other, then a midpoint potential of the drive coil 3 is selected as a common potential and a potential of each complementary pair circuit is controlled uniformly to be V to the common potential.

Title: Come-along
Inventor: SANBONSUGI KIYOSHI
IPC: H02G1/02
Filed: 1993-03-12
Abstract: PURPOSE:To prevent the disconnection accident of an electric wire provided with a protrusion in a stretch operation by a method wherein the wire part of the electric wire provided with the protrusion is gripped before a come-along body and an electric-wire rotation-preventing utensil which can be moved freely in the direction of tension exerted on the electric wire is provided. CONSTITUTION:An electric-wire rotation-preventing utensil 18 is provided before a come-along body 13. The electric-wire rotation-preventing utensil 18 grips a wire part itself excluding a fin part for an electric wire provided with the protrusion (the fin). Consequently, even when a turning effort acts on the electric wire, e.g. due to the large return torque of the electric wire itself, the electric- wire rotation-preventing utensil 18 grips the electric wire provided with the fin, and the turning effort is avoided before the come-along body 11 and does not act on the come-along 11. That is to say, the electric wire provided with the fin is not turned inside an arrow 12 in the come-along 11. Thereby, it is possible to prevent the disconnection accident of the electric wire in a sagging operation.
