Abstract: A height adjusting mechanism for a framework that supports a multiplicity of ground working tools of an agricultural implement operating at variable depths of ground penetration is disclosed. The variability is achieved by rotation of framework supporting rock shafts (5, 6) pivoting around pivot points (C1, C2) on wheel supported wheel frames (1), which in turn support the rock shafts (5, 6); rotation causes the lateral spacing of the wheels (2) to vary also. Additionally, flexibility of the framework optionally is provided by having certain fastenings and pivotal attachments between framework members in the form of resilient connections. The novel flexible framework is not critical to operation of the height adjusting mechanism, the latter being operable also with rigid framework.

Abstract: In a magnetic recording apparatus with a magnetic head, superconductive layers (6, 17, 106) are formed over at least flux generating surfaces of the magnetic head and normal conductive regions (8, 21, 108) for passing the flux are provided in the superconductive layers, over the flux generating surfaces, so as not to form a closed magnetic circuit. The minimum unit size (recording wavelength) of the reversible spontaneous magnetization in magnetic recording can be reduced from the order of 1 µm to that of 0.1 µm of submicron. Thus it is possible to increase the surface recording density of magnetic recording to more than 100 Mb/in², comparable to the density achieved by the opto-magnetic recording. This in turn makes it possible to provide a large disc apparatus having a capacity of 60 MB or more.

Abstract: In known Faraday effect current sensors, light is fed into a polarizer, through a coil of field-sensitive optical fiber, and into a polarization measuring device. Such a current sensor can provide greater accuracy of current measurement by using a polarizing optical fiber as its polarizer and splicing the polarizing fiber to the input end of the optical fiber coil. The exit end of the optical fiber coil can be spliced to a second polarizing optical fiber, the other end of which is optically connected to a photodetector. In another embodiment, a mirror at the exit end of the optical fiber coil reflects light back through the coil to second and third polarizing fibers which in turn are optically connected to a pair of photodetectors, thus doubling the Faraday rotation while canceling out reciprocal optical effects.
