Abstract: Disclosed is a method for recording and reproducing sector control information to and from a novel magneto-optical disk (31) to which the so-called erasure type data reproduction method or data-embossed type reproduction method applies. On the magneto-optical disk (31), sector control information is recorded onto a sector control information recording region (34) at a track recording density lower than that of a data recording region (33). When data is recorded on the disk (31) at a high track density, the sector control information is recorded in such a manner that the information will not exist on adjacent tracks (36) in the same rotating direction of the disk.

Abstract: The received pi/4 - QPSK signal (r) is converted (101) to N baseband signals, in comparison to an N - phase clock (clk). After differential decoding (102,103), a decision error (ea) is calculated (112) for each of the N baseband signals (p3). The squared errors are integrated over a time period dependent upon a frame signal (f), and the clock phase giving the minimum squared error is found. The baseband signal which corresponds to this clock phase is then chosen as correct.

Abstract: A movement actuator includes an elongate filament made of a flexible material, and a strip of shape memory alloy disposed on the surface of one side of the filament. The shape memory alloy is responsive to actuation signals, heat or electrical signals, for changing its shape and when its shape changes, it causes the filament to move, i.e., bend, to accommodate the change in shape of the alloy. Also included is a signal supply device for selectively applying heat signals or electrical current to the strip of shape memory alloy to cause the alloy to change its shape and cause the filament to bend. Other patterns for the shape memory alloy could be disposed on the filament to cause other kinds of movements. For example, a helical pattern of the shape memory alloy about the filament would cause the filament to twist when the helical pattern were caused to shorten or lengthen.

Abstract: A lubricant reservoir system for a magnetic disk near contact data storage device, which rotates in unison with the disk assembly to replace lubricant depleted from the disk surface over the life of the device, includes reservoir chambers in disk spacers with lubricant metering provided by restricted passages or textured surfaces extending radially outward from the reservoir chamber while replacement air passages extend radially inward to replace dispensed lubricant. The metered lubricant is delivered to the disk surface at a location where the surface confronting the disk is made compliant with the disk surface and the adjoining surface is beveled to form an angle of more than 90 degrees with the disk surface thereby preventing migration of lubricant away from the disk. Nonwettable surfaces may be used in metering passages, air passages, and on some beveled surfaces to further control lubricant metering. In operation, the high G forces induced by rotation cause lubricant to be metered to the disk while the same small metering passages function as a barrier when the disk assembly is not rotating.

Abstract: A method of monitoring the concentration of certain plating bath major constituents such as acid is provided which is insensitive to the effects of hydrogen produced during plating. The method involves applying an ac signal superimposed on a dc potential to a sensing electrode in contact with the solution, producing an ac response current. The steady state value of the ac response current is then measured and provides an accurate indication of the acid concentration within the solution. The method can be performed using a single sensing electrode. Furthermore, the method complements and is usually integrated with known voltammetric techniques and equipment suitable for analysis of other plating bath constituents.

Abstract: There is disclosed a method of treating a water-swellable clay after the clay has been mined and dried to improve its properties when in contact with contaminated water. After the common initial drying of the clay to a moisture content of 12% by weight or less, the clay is impregnated with an aqueous solution containing a dissolved, water-soluble polymer, in an amount of at least about 0.5% by weight based on the dry weight of the clay, and the clay is wetted to a moisture content of more than 12% by weight, preferably at least about 15% or more, based on the dry weight of the clay, and then redried to a moisture content of 12% by weight or less, based on the dry weight of the clay. This rewetting step to hydrate and polymer-impregnate the clay, and then redrying the clay, unexpectedly improves the contaminated water absorbency, and viscosity properties when the clay is in contact with contaminated water; unexpectedly increases the rheology properties of the clays for oil well drilling fluids and lost circulation fields when contaminated water is encountered during drilling, enhances the clay properties when used as a suspending agent in the cosmetics and pharmaceutical industries when the composition contains a dissolved, inorganic salt and/or an organic liquid; and provides unexpectedly increased contaminated water-absorption in forming water-swellable clay-based water barriers.
