Abstract: A soft magnetic film includes Fe as a major constituent; at least one element M selected from the group consisting of Zr, Hr, V, Nb, Ta, W, Mo, and rare earth elements (excluding Sm); at least one element L selected from the group consisting of Ti, Sn, Sm, and Si: and at least one element R selected from the group consisting of O, C, and N. The film has a structure including a mixture of an amorphous phase containing a large amount of the oxide of the element M and a fine crystalline phase containing a large amount of Fe, and the fine crystalline phase further contains the element L. Thin film magnetic heads, planar magnetic elements, and filters using the soft magnetic film are also disclosed.

Abstract: In a magnetic film forming method, a plurality of chips formed of Fe.sub.3 O.sub.4 and a plurality of chips formed of HfO.sub.2 are disposed on a target formed of Fe. The composition ratio of a Fe--Hf--O film can be set within a proper range by adjusting the numbers of the up said two kind of chips.

Abstract: An adjustable hinge for pivotally connecting a door member to a receptacle member is disclosed. The hinge comprises a first structure having a pivotal male member; a second structure secured to the receptacle member, the second structure and the first structure being detachably connectable; and a third structure secured to the door member and having a female member with which the male member is latchedly engageable.

Abstract: A graphite body which is capable of connecting a plurality of the graphite bodies one by one. The graphite body includes one connecting end surface having a T-shaped mound and the other connecting end surface having an inverted T-shaped groove so that the graphite bodies may be connected by means of the mound and groove. The mound and groove each have a width linearly varied in the longitudinal direction thereof.
