A wagon 1 comprises a first wagon 10 including a lower face plate 12 and an upper face plate 11 constituting storage space, and a second wagon 20 to be stored within the storage space of the first wagon 10. The longitudinal side edges of the upper face plate 11 of said first wagon 10 is equipped with auxiliary table plates 15 rotatably connected thereto, and the first and second wagons 10, 20 are formed to rotate with the rotary axis set to a center column 30 mounted to the center of the upper and lower face plates 11, 25, 12, 21. The second wagon 20 can be moved from a first position where the wagon is completely stored within the first wagon 10 to a second position taking an angle of 90 degrees from the first wagon, and the auxiliary tables 15 can each be pivoted from a position hanging from the upper face plate 11 to a position leveled with the upper face plate 11. The second wagon 20 comprises a supporting mechanism equipped to the lower face plate 21, so that when the second wagon 20 is rotated to said second position, the supporting mechanism 95 supports the second wagon 20 to the leveled position.

Since split electrodes are disposed along the x-axis of an AT cut quartz crystal plate on its ultrathin vibratory portion formed integrally with a thick frame-like marginal portion surrounding it, desired acoustic coupling can be obtained although the split electrodes are disposed closely to such an extent as not to cause shorting between them. It is therefore possible to obtain, with a satisfactory yield, filter elements which have center frequencies in the range greater than about ten megahertz and sufficiently wide passbands.

A rotational plastic compression molding apparatus including a plurality of circumferentially spaced female molds and a plurality of circumferentially spaced male molds cooperating respectively with the plurality of the female molds. The female molds and the male molds are rotated in synchronism and thus moved round successively through a material loading zone, a compression molding zone and an article discharge zone. In the material loading zone and the article discharge zone, each said female mold and each corresponding mold are maintained in a spaced-apart inoperative relation, and in the compression molding zone, they are maintained in an approaching operative relation to define a mold space therebetween. In the material loading zone, a heat-melted plastic material is loaded in the female molds, and in the article discharge zone, the compression-molded plastic article is discharged from between each said female mold and each corresponding male mold.

A magnetic head for digital signal recording/reproducing (FIG. 11) having a C-ring shaped core (11.1) with a gap (G) for introducing leakage flux of a recording medium, a conductor (11.2, Y) for generating bias flux in hard magnetization axis of the core (11.1), apparatus (10.3, 11.3) for illuminating the core (11.1) with polarized optical beam, apparatus (11.4) for analyzing beam reflected by the core to convert polarization rotation to optical strength, and photo-detector (12.5) for providing electrical output signal relating to optical strength. The core is small enough to have a single magnetic domain, and is magnetized in the whole area because of the presence of the bias flux in spite of weak leakage signal flux, thus, the core has the capability to amplify signal flux, thus, the present head has high sensitivity and is capable of detecting flux in small area to be used for high density recording higher than 8000 bits/mm.

.gamma.-Fe.sub.2 O.sub.3 film with at least one additive selected from the group consisting of Pd, Au, Pt, Rh, Ag, Ru, Ir, and Os, especially Os are disclosed. Reduction from .alpha.-Fe.sub.2 O.sub.3 to Fe.sub.3 O.sub.4 is accelerated by additive Os to achieve a uniform reduction and increase the ratio of magnetic phase in the film. .gamma.-Fe.sub.2 O.sub.3 film medium with Os improved saturation magnetization and increased coercive force in proportion to amount of additive Os. Application of an external field to said film introduces magnetic anisotropy into said film, therefore said film medium improves coercive force and squareness of hysteresis loop by the introduction of anisotropy. .gamma.-Fe.sub.2 O.sub.3 crystal grain is prepared by additive Os to obtain fine grain. The resultant .gamma.-Fe.sub.2 O.sub.3 film medium a decreased noise level.
