Title: Magnetism erasing method
Inventor: MATSUMOTO TAKASHI
IPC: G11B5/024
Filed: 1985-10-22
Abstract: PURPOSE:To record residual noise and distortion factor by acting a magnetic field whose residual magnetization direction along the recording face is inverted at the surface layer and the deep layer beneath the surface layer. CONSTITUTION:Permanent magnets 10, 11 are directed to the recording face 6 and arranged with an interval in the relative moving direction 12 with a magnetic recording medium 1. The polarity of the succeeding magnet 11 is opposite to that of the preceding magnet 10, the deep layer part 4 of a magnetic layer 2 and the surface layer part 7 are saturated in one direction 5 by the magnet 10 attened with the relative movement and only the surface layer part 7 is magnetized in the reverse direction 8 by the magnet 11. When the direction of residual magnetization is inverted together in this way, a closed magnetic path is formed, the magnetic flux appearing externally is less and the residual magnetic flux is effectively less and then the residual noise and distortion factor are decreased.

Title: Image forming method
Inventor: HAMADA JUNICHI
IPC: G03G13/01
Filed: 1984-11-07
Abstract: PURPOSE:To reproduce sharply an image consisting of chromatic and achromatic colors with high accuracy by using the 1st electrostatic charge image of a negative consisting of the potential pattern of both positive and negative polarities formed on an image carrying body as the 1st image information and the positive and negative ion current passing through an ion current control screen as the 2nd image information. CONSTITUTION:The entire surface of a photosensitive screen 17 and photosensitive layer 56 is electrostatically charged to negative and is subjected to image exposing by the light from an original 44. A dichroic mirror 47 reflects the light of an R component and allows the transmission of the light of B and G components. The surface potential of a photosensitive body 1 is the image information of the negative. The positive ion particles pass selectively through the negative electrostatic charge region of the screen 17 and the negative ion particles pass through the region not electrostatically charged to negative when the positive and negative ion particles are respectively projected from a charge particle source 19. The charge of the positive or negative polarity is then selectively left on an insulating layer 57 by the positive charge on the photosensitive layer 56 and the electrostatic latent image separated with the positive chromatic levels G, B, C and the negative chromatic levels Y, R, M on both sides of the achromatic levels (w), (b) is formed. The optional chromatic image is formed to a visible image by development.

Filed: 1984-11-09
Abstract: PURPOSE:To shorten the feed interval of originals and improve work efficiency by providing a means detecting the displacement, at the discharge, of the last sheet material discharged and conveyed among the stacked and stored originals in a copying machine or the like. CONSTITUTION:An original feeder is operated, originals M are taken out from the top in sequence, and when the last original is displaced by a paper feeding roller 2, then the original is pinched and conveyed by a detecting roller 3, the detecting roller 3 is rotated by friction, a disk 4 is also rotated, peripheral slits activate a photo-interrupter 5, thus the last original is detected, and the subsequent paper feeding is stopped. Accordingly, in case signals are transmitted/ received according to the sequence within one equipment or between two or more equipment, the information can be conveyed in advance. That is, output signals for originals can be transmitted in advance only except for the last original, thereby the feed interval of originals can be shortened and the processing speed can be increased.

Title: Graft polymer having polyurethane-graft trank, its production and use
Inventor: MATEIASU KUROOGERU
IPC: C08F283/00
Filed: 1988-09-21
Abstract: Graft polymers in which vinyl carboxylates and optionally further ethylenically unsaturated monomers are grafted polymerically onto polyurethane backbones by free-radical-initiated graft polymerisation, and products of the hydrolysis of the graft polymers, can be obtained by grafting vinyl carboxylates having 3 to 20 carbon atoms and optionally further ethylenically unsaturated, polymerisable and optionally copolymerisable monomers in amounts of from 10 to 99% by weight, based on the graft polymer, onto a polyurethane backbone containing at least 2 urethane groups in the molecule, and, if desired, subsequently partially or fully hydrolysing and/or alcoholising the vinyl ester units and any further hydrolysable monomer units in the grafted-on polymer radicals of the graft polymers. Vinyl esters which are preferred for grafting are vinyl acetate and/or vinyl propionate and possibly vinyl versatate. The graft polymerisation is carried out in solution or in bulk and can also be carried out in emulsion or suspension. Unhydrolysed graft polymers are suitable, inter alia, as adhesives, in particular as hot-melt adhesives. Fully and partially hydrolysed graft polymers are suitable, inter alia, for the production of films. Depending on the polyurethane backbone, the degree of grafting, the degree of hydrolysis and the type of grafted monomers, the graft polymers, compared with polyvinyl alcohol, can have significantly lower melting points, and are thus advantageously suitable for the production of pressed or extruded films under mild temperature conditions without the additional use of organic plasticisers. Hydrolysed graft polymers are furthermore suitable, inter alia, as adhesives.

Title: Measurement of molten iron/slag drip distribution for blast furnace
Inventor: KIGUCHI JUNPEI
IPC: G01N33/20
Filed: 1986-10-02
Abstract: PURPOSE:To accurately measure an actual radial drip distribution within a furnace in a molten iron/slag drip area during the operating of a blast furnace, by inserting self-melt sensors, equipped with different kinds of metal tracers along the length thereof, into the blast furnace radially. CONSTITUTION:Metal tracer-equipped self melt sensors 1 is internally provided with a plurality of metal tracers M1, M2, M3, M4 and M5 in the center of a round-bar shaped refractory material 2 at a proper interval, the circumference of which 2 is covered with steel material S. the quality of the refractory material 2 is such that the refractoriness thereof allows it to consume under a relatively-short-time corrosion by molten iron and slag 6 under operating conditions of a blast furnace and preferably, it is an Al2O3 based refractory. The sensor 1 is inserted into a drip area of the molten ion and slag 6 or slightly above it in the radial direction of the furnace from the side wall of the blast furnace. The corrosion rate of the sensors 1 is high at the portion with more drips of molten iron and slag 6 and low at the portion with less drips thereof. Thus, secular analysis is conducted to determine the type and content of metal tracers in the dipped molten iron sent out being mixed with the metal tracers thereby enabling the obtaining of a radial distribution of the drips of molten iron and slag.

IPC: H02K33/18
Filed: 1988-09-20
Abstract: PURPOSE:To obtain a linear actuator having good vibration characteristics by constituting an apparatus so that the center of gravity of a carriage is approximately on the thrust vector line of a coil of voice coil motor, when said carriage moves linearly according to the movement of said coil of voice coil motor. CONSTITUTION:The main body of a carriage 30 has a box-type structure of which the hollow part has a voice coil motor composed of a yoke 10, a coil 12 and magnets 15a, 15b built-in, and the coil 12 and respective beads 20, 21 of said motor are arranged in nearly opposed positions at the front and rear ends of said main body. Therefore, the center of gravity G of the main body of said carriage 30 is set nearly on the center line of said coil 12. Accordingly, in a state where the carriage 30 moves linearly, a thrust vector Ft at the time of drive of the coil 12 and an inertial force vector Fg applied to the mass of said carriage 30 are generated nearly on the same line. As a result, the generation of a pitching motion based on the generation of a moment centering on said center of gravity G is controlled substantially at the time of a linear motion of the carriage 30.

Title: Connection controller and connection control method
Inventor: TAKI NOBUHIRO
IPC: H04N5/781
Filed: 1998-08-21
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption by inactivating a status generating section in the case that a detection result of a detection section indicates a lost status signal of an opposite party. SOLUTION: An opposite party status detection section 24 activates a detection signal S1 in response to an active status signal ST2 when the status signal ST2 of an opposite party is active and outputs a detection signal S2 to a status control section. Furthermore, when the opposite party status detection section 24 detects an inactive status signal of the opposite party, the opposite party status detection section 24 inactivates the detection signal S2. The status control section inactivates a control signal S1 given to an own status generating section 23 in response to the inactive detection signal S2 and the own status generating section 23 is inactive in response to the inactive control signal S1. Thus, an own status signal ST1 is inactive.  The status control section inactivates the own status signal ST1 based on the detection signal S2 being a result of detecting the inactive status signal ST2 of the opposite party.
