Title: Magnetic bubble generator
Inventor: AMATSU MASASHI
IPC: G11C19/08
Filed: 1986-03-04
Abstract: PURPOSE:To prevent a crossing part with a conductor pattern from being generated at the bubble transfer path of a hammer type pattern, and to prevent a bubble transfer characteristic from deteriorating, by putting the gap part of a hair-pin type conductor pattern along the side plane of the arm part of the hammer type pattern, and making advance its aperture part in the traveling direction of a bubble. CONSTITUTION:A hair-pin type conductor pattern 12 is arranged so that the gap part 13 of the pattern is put along the side plane B-B' of the arm part 11 of a hammer type pattern 10, and also, its aperture part 14 is made advance in the traveling direction of the bubble shown in arrow head (a). And a tip end point (b) at the arm part 11 of the hammer type pattern 10 is designated as the generating part of the bubble, and the bubble is transferred along the side plane of the arm part 11. At such a case, the conductor pattern 12 does not cross the transfer path of the bubble, and also, the expanding/contracting direction of a generated bubble coincides with the transfer direction of the bubble. In this way, an unnecessary bubble due to the division of a stripe magnetic domain is hard to generate, and the transfer characteristic can be improved without deteriorating the current characteristic of a generator.

Title: Centrifugal extractor
Inventor: YOSHINAGA SHIYOUJI
IPC: B01D11/04
Filed: 1978-04-19
Abstract: PURPOSE: A highly efficient, inexpensive centrifugal extractor has a construction such that at least one of light or heavy weight liquid advancing to the extracting chamber is guided to dispersing device.  
     CONSTITUTION: Light and heavy liquid injection pipes 20 and 5 are provided at their ends with distribution pipes having a plurality of liquid jet holes 25 and 27 in lengthwise direction. The holes 25 and 27 are faced each other and lined in the direction of the shaft 2. Liquids from pumps are distributed from the pipe 24 and 26 into each of light and heavy continuous liquid layers 12 and 11. Such construction causes each of the driving force of liquids passing the holes 25 and 27 to be equal to each of the discharging pressure of the heavy and light weight liquid feed pumps. As a result, the velocities of liquids passing through the holes 25, 27 can be increased to greater than 1.5 m/s so as to enhance the extraction efficiency. The greater the number of the injection pipes 20 and 5 for light and heavy liquid, the better the efficiency.

Title: Position detecting method of movable calory meter
Inventor: NISHIMURA HIDETOMO
IPC: G01T1/29
Filed: 1979-04-16
Abstract: PURPOSE: To enable the angle of the movable calory meter to a stationary calory meter to be obtained automatically by measuring the electrostatic capacity between the movable calory meter and stationary calory meter.  
     CONSTITUTION: A movable calory meter 1 is insulated from a vacuum vessel 3 by an insulator 7. A stationary calory meter 4 is also insulated from the vacuum vessel 3 by an insulator 8. The electrostatic capacity between the movable calory meter 1 and stationary calory meter 4 depends only upon the parallelism of the both. Hence, from this electrostatic capacity, it is possible to detect the angle of the movable calory meter to the stationary calory meter.

Title: Formable magnetic wedge and method of mounting the same
Inventor: ISHIHARA KENJI
IPC: H02K3/493
Filed: 1980-04-09
Abstract: PURPOSE:To improve the workability in a method by mounting a foamable magnetic wedge by molding foamable resin containing soft magnetic material with a width narrower than the opening of a slot and bonding a hard synthetic resin film having a broad width on one side of the molded resin to form a magnetic wedge, thereby preventing the effluence of the foamable resin out of the slot. CONSTITUTION:Foamable resin containing soft magnetic material such as iron powder or the like is molded in a strip having a width narrower than the width of the opening of a slot to form a foamable resin unit 11a. This resin unit 11a is bonded to the widthwise central part of the hard synthetic resin film 11b on which an adhesive 11c is adhered on one side with a width wider than the resin unit 11a to form a magnetic wedge. After the wedge is mounted on the opening of the slot by utilizing the adhesive 11c retained on both sides of the resin unit 11a, it is heated and foamed, and resin is filled in the gap 2b at the upper part of the slot. Thus, the foamable resin does not flow out externally of the slot even without a mold, and the workability can be improved.

The range of the direction of the normal line f1 with respect to the vane surface of the points starting from the turn starting point D1 of the vane of the point E1 turned back by 0.5 turn from the turn end point C1 covers at least 360 deg., when the both ranges of the direction of the normal line with respect to a pair of vanes 1 and 1' which are rectilinearly symmetrical are added, i.e., when 0-180 deg. in the direction of the normal line on the vane in the range between D1 E1 and 180-360 deg. in the direction of the normal line on the vane in the range between E'1 D'1 are added. Therefore, in the phase where the contact of the sipral surface is cut-off, the spiral surface of a fixed vane 1' and the spiral surface of a transferring vane 2' are attached, and generation of penetration phenomenon is prevented.
