Title: Manufacture of rare-earth metal intermetallic compound magnet
Inventor: OKONOGI ITARU
IPC: H01F1/055
Filed: 1978-11-07
Abstract: PURPOSE:To improve the crystal orientation of a rare-earth metal intermetallic compound magnet and at the same time to facilitate its quantity production, by forming a mold composed of a powder of intermetallic compound of rare-earth metals and transition metals added with resin powder as binder. CONSTITUTION:A powder of intermetallic compound composed of rare-earth metals (R) and transition metals (M), in the range from R2M7 to R2M17, is added with resin powder as binder. A mold is formed by applying a magnetic field and pressure on this substance. For resin powder, thermo-setting resin, such as epoxy, polyester, phenol, melamine, urea, or thermo-plastic resin, such as vinyl, acryl, ABS, polyetylene, may be used. The grain diameter is set at 0.01-100mu. By this, using a resin powder whose grain diameter is about the same as that of the magnetic powder, 2-200mu, it is possible to disperse the binder uniformly, improve the magnetic field orientation, simplify the molding and facilitate quantity production.

Filed: 1978-11-07
Abstract: PURPOSE: To increase brake power by converting a drag action of friction pads, generated inevitably upon braking, into an oscillating force of a caliper, coupled to a support axle with a multiple thread screw, in a direction in which the brake power is generated.  
     CONSTITUTION: When hydraulic pressure is delivered into an oil chamber 9, a piston 8 is forwarded in a cylinder 7 and a friction pad 10 is pushed against a disk 1. In this case, a support axle 3, arranged and fixed so as to be in tangential direction at an outer location of a diameter of a rim portion of the disk 1, and a caliper 2, fitted and screwed to the axle 3 by a multiple thread scfew 4, are moved toward a direction shown by an arrow sign B, thereby, another friction pad 11 is pushed against the disk 1, and thus, a brake power may be obtained. The friction pad 10 is dragged toward the rotating direction when pushed against the disk 1, thereby, a movement toward the same direction is generated in the caliper 2 held by the friction pad 10, and thus an oscillation, in a direction in which the brake power is generated, is caused by the multiple thread screw 4.

SOLUTION: The hydrochloric acid is added to the chalcopyrite and the chalcopyrite is heat treated for about 1 to 6 hours at >=110 deg.C, more preferably about 120 to 140 deg.C. At this time, the chalcopyrite is preferably used in the powder form of about <=150p, more particularly about <=70μm. The concn. of the hydrochloric acid is preferably as high as about >=4 mol/dm<3> , more particularly about 6 to 12 mol/dm<3> . the amt. of the hydrochlotic acid to be used is adequately from about tshe amt. at which the entire part of the ore is soaked to about two times the volume of the ore. The copper in the chalcopyrite is converted to the compd. soluble in water by such heat treatment. The water is thereafter added to the chalcopyrite to leach the soluble copper compd. in the heating product.  After this copper leaching liquid is separated, the copper is recovered at a high yield of about >=99% by a known method.

Title: Track position detecting system
Inventor: IWANAGA TOSHIAKI
IPC: G11B23/30
Filed: 1983-07-28
Abstract: PURPOSE:To attain the detection for track position with use of no magnetism and therefore to realize the record/reproduction with high density, by detecting the position of an information track from a change of electrostatic capacity between a conductive track information groove of a magnetic recording medium and paired electrodes of a head for magnetic record/reproduction. CONSTITUTION:For a magnetic recording medium 4, a conductive groove 7 is formed on a nonmagnetic substrate 8 containing a groove of an array pattern corresponding to the information. Then a nonconductive magnetic layer 6 and a protecting layer 5 are formed over the groove 7. A head 1 contains paired electrodes 3a and 3b formed on an end face in the track direction of a magnetic head 15 for magnetic record/reproduction. In this case, the electrostatic capacity is provided between the groove 7 and electrodes 3a and 3b, respectively. This electrostatic capacity varies in response to the array pattern of the groove 7. As a result, the track follow-up is possible by detecting differentially the change of the electrostatic capacity in the form of an error signal. Furthermore the track density can be increased by reducing the width of the groove 7 and decreasing relatively the width of an electrode plate.

Title: Roll forming machine
Inventor: FUJIMOTO SEIGO
IPC: B30B9/28
Filed: 1985-06-24
Abstract: PURPOSE:To form briquettes having a uniform density by turning a bearing plate to automatically adjust the twist angle of compressing rolls according to frictional force when the frictional force generated between the compressing rolls and the briquettes exceeds a prescribed value thereby automatically controlling the delivery speed. CONSTITUTION:The frictional force acts on the compressing rolls 5, 5 and the rolls 5 pivotally supported at one end to the machine body side are tried to be twisted by the reaction thereof as the grass continuously pushed from a pickup part 4 into a molding chamber 6 is successively compressed by the rolls 5. The bearing plate 18 pivotally supporting the other end side of the rolls 5 is turned by overcoming the energizing force of a spring 19 when the frictional force exceeds the prescribed value. The briquettes compressed and molded to a circular cylindrical shape are thereby pushed out. The pushing out speed is automatically controlled according to the degree at which the grass is compressed. The briquettes having always the uniform density are thus formed.

Filed: 1979-10-29
Abstract: PURPOSE:To ensure the supply of AC output without the interruption thereof even during the interruption of DC power by providing the DC-AC converter using a constantly power supplied battery as the power source. CONSTITUTION:DC voltage is converted into AC by a half bridge circuit 6 and AC outputs A1 and A2 are obtained from a constant voltage transformer 8. Further, a battery 11 is constantly supplied with power through the full-wave rectification of the output A2. DC power interruption is detected by a current transformer 1A so that the change-over of a change-over contactor 14 is performed for a half-bridge circuit 13 using the battery 11 as input power source. Thus-obtained output is impressed to the primary side of a constant voltage transformer 8 via the normally closed contact of the contactor 14 for obtaining the AC output A1 equivalent to that obtained normally. Thereby, power can be continuously supplied while AC output is little interrupted.
