The temperature sensitive element is produced by compacting the fine grain powders at a temperature higher than the transition temperature range. According to the present invention, it is possible to use a polycrystalline rare earth cobalt alloy material in the field where low Curie point ferrite has been used or where bimetals have been used for a thermal valve or a temperature controlling device.

摘要： In a method for forming an adhesive layer on the surface of a workpiece before the formation of a coating film containing a powder on the workpiece, the present invention provides a method for forming the adhesive layer having a desired thickness. This object is achieved by the following method: An adhesive layer formation medium m1 coated with an adhesive material is made to collide with a workpiece W so that the adhesive material is transferred from the adhesive layer formation medium m1 to the workpiece W and forms an adhesive layer on the workpiece. An adhesive layer having a desired thickness can be formed on the workpiece by regulating the thickness of the adhesive material applied to the surface of the adhesive layer formation medium (i.e. the amount of the adhesive material held by a single adhesive layer formation medium). This enables the thickness of the powder coating as the final product to be controlled as desired.
摘要翻译：在形成在工件上含有粉末的涂膜之前在工件表面上形成粘合剂层的方法中，本发明提供了形成具有所需厚度的粘合剂层的方法。该目的通过以下方法实现：使涂覆有粘合剂材料的粘合层形成介质m 1与工件W碰撞，使得粘合剂材料从粘合剂层形成介质m 1转移到工件W并形成工件上的粘合剂层。可以通过调节施加在粘合剂层形成介质的表面上的粘合剂材料的厚度（即，由单一的粘合剂层形成介质保持的粘合剂材料的量），在工件上形成具有所需厚度的粘合剂层。这使得根据需要可以控制作为最终产品的粉末涂料的厚度。

摘要： A powder compaction method in which a powder p is filled by air tapping or other suitable method into a mold 1, then while the mold 1 being filled with the powder, the powder particles are bound with each other without application of force from outside the mold to form a compact C, and then the compact C is taken out from the mold 1. This method produces a variety of shapes of the compact far greater than in conventional methods, and net shape manufacturing of products with complex shapes is made possible by this method. Because this method uses far less binder compared to MIM and PIM that are expected as methods for producing products with complicated shapes, the time needed for elimination of the binder is much shorter than in MIM and PIM.

摘要： The present invention relates to a packing method in which a material (p) is fed into a space comprising an opening (4c) for feeding the material and a space (4d) to be packed with said material, and said space is subjected to air tapping, that is, switching of air-pressure from a low air-pressure state to a high air-pressure state alternately, thereby packing the material into the space (4d) at a high packing-density. The use of air tapping for packing a material into a space makes the packing-density of the material uniform.

摘要： A perpendicular magnetic recording medium is fabricated based on R.sub.21-60 (Fe.sub.1-y Co.sub.y).sub.z M.sub.0-10 wherein z is balance and at least 70 at % of R is Nd and/or Pr, the balance of R being one or more of other rare earth elements, and wherein y is less than 0.5 by atomic ratio. M is at least one of various additional metal elements. The Curie temperature Tc is between 70.degree. to 250.degree. C.; the saturation magnetization Ms is about 450 emu/cc or more; the uniaxial perpendicular magnetic anisotropy constant Ku of 2.5.times.10.sup.6 erg/cc or more is attained. Kerr rotation angle is 0.3 degree or more, which provides a magneto-optic recording medium. Since light rare earth elements having the collinear alignment of magnetic moment with Fe are used as a key element, it is possible to fabricate uniform perpendicular magnetic anisotropy thin films in a mass production scale at a low cost.

摘要： Green compacts for sintered ceramic bodies and for sintered permanent magnets are produced by first preparing outside a die press machine a mold which contains a rubber portion in at least a side portion. The mold cavity is then filled with the fine powder which is to form the compact to a density which is at least 1.2 times the natural filling density of the powder. The filled rubber mold is then placed in the die press machine and compacted in the die press machine to produce the green compact. The natural filling density is obtained by allowing the powder to fall from a powder pan into the rubber mold until the powder reaches the top of the rubber mold, where the distance from the powder pan to the bottom of the rubber mold is 3.7 times the depth of the cavity of the rubber mold.
