Abstract: A method for the treatment of wool so as to impart shrink resistance comprising, in any order, the steps of:-
     i) treating the wool with a proteolytic enzyme, and   ii) subjecting the wool to either or both of an oxidative treatment and treatment with a polymer,    with the proviso that when the oxidative treatment is used alone it comprises a wet chlorination process.
     The method may be operated either as essentially a batch process or as a process involving a combination of continuous and batch treatments.

Abstract: The invention provides an apparatus for coating a web (3) which has a first surface (3a) having been coated and a second surface (3b) opposite to the first surface (3a). A support roll (11) has a supporting surface (11a) around which the web (3) is adapted to be conveyed and an air-jetting device for jetting air through the supporting surface (11a) onto the first surface (3a) of the web so that the web (3) is supported by air without coming into contact with the supporting surface (11a). A coater (2) is disposed to face the supporting surface (11a) so as to coat the second surface (3b) of the web (3). The apparatus is provided with a heater for heating air to be jetted by the air-jetting device so that the temperature of the air becomes higher than that of the first surface (3a) of the web.

Abstract: Digital audio and video signal are recorded on successive oblique tracks formed on a video tape, and reproduced therefrom by reproducing heads which can be movable in a direction transverse to the tracks by means of a bimorph device so that at least a plurality of tracks including one field of video and audio signals are skipped in a variable tape speed mode. Track portions provided for the audio signal are arranged at both ends of the video tracks. In a mode in which the read head ships a field the signal level of the audio signal reproduced from one end portion of the audio tracks is gradually reduced at an end of tracking by the head, while the signal level of the audio signal reproduced from other end portion of a new field track portion is gradually increased so that a cross-fade function can be performed.

Abstract: An automatic servo gain control system for an optical disk player apparatus is capable of controlling an open-loop servo gain to be constant, regardless of parameter variations in­cluding variations in the optical head actuator gain. The system includes a gain control circuit that varies a gain for a first signal (a) indicative of a positional relationship between the optical head and an optical disk based on a second signal (b) providing light intensity information. The system further includes an oscillator (11) that produces an output at a frequency within a servo frequency band of the optical head actuator and that is introduced into a servo loop via an operational amplifier (7). Signal (e, f) values at an input side and an output side of the operational amplifier (7) in the servo loop are compared so as to vary the gain for the first signal (a) based on a difference between the input and output signal (e, f) values. The system operates to control the input and output signal (e, f) values to be at a predeter­mined rate, thereby keeping the open-loop servo gain constant.

Abstract: A sense amplifier circuit for use in a ROM comprises an excess charge detecting circuit (24) for producing a detection output when a potential of a bit line (BL) exceeds a normal value, and an excess charge discharging circuit (25) which operates in response to said excess charge detecting circuit (24) for discharging a bit line charge and for returning the bit line potential to the normal value. 
     The excess charge detecting circuit and the excess charge discharge circuit can be realized by a diode-connected transistor (24d,25c) connected between the bit line (BL) and an inverter (23) of the sense amplifier. When the bit line potential is about to exceed the predetermined value, the transistor turns on to prevent the bit line potential from exceeding the predetermined value.

Abstract: A method for etching titanium nitride local interconnects 48 is disclosed. A layer of titanium nitride 43 is either formed as a by-product of the formation of titanium silicide 20, 22, 28 by direct reaction or by deposition. The location of the interconnects is defined by patterning photoresist 46 at the desired locations. A plasma etch using a chlorine-bearing agent such as CC1₄ as the etchant etches the titanium nitride 43 anisotropically at those locations covered by photoresist, and isotropically elsewhere, so that filaments of the titanium nitride 43 are removed without undercutting the photoresist mask 46. The etch is selective relative to the underlying material, such as a refractory metal silicide, refractory metals, or silicon, due to the passivation of the underlying material by the carbon atoms of the CC1₄. The selectivity, together with the selective anisotropy, even allows significant overetch of the material to remove the filaments without undercutting the masked interconnect material 48.

Abstract: A solder-stop resist (5) and a positive-working photoresist (6) are applied in succession over the entire surface of the printed circuit board, after which the photoresist (6) is selectively exposed, preferably with the aid of laser radiation (Ls), in the region of the plated-through holes (3) and/or solder pads (4) and developed. The solder-resist (5) in the regions not protected by the photoresist (6), i.e. in the regions of the plated-through holes (3) and/or solder pads (4), is then stripped and, as a final step, the remaining photoresist (6) is also stripped. The method according to the invention is suitable, in particular, for the application of a solder-stop coating to three-dimensional printed circuit boards since in this case conventional masking techniques cannot be used for structuring the solder-resist.

Abstract: A system for permitting data transfers between a high speed bus and a low speed bus which operate independently and asynchronously. When the low speed bus requires access to the high speed bus, the busy status of the latter bus is determined and transfers are made to the high speed bus at high speed when such bus is not busy. When the high speed bus requires access to the low speed bus, if the low speed bus is busy the requesting master on the high speed bus is temporarily placed in a pending status and is removed from its tenure on the high speed bus, so that the high speed bus is free to handle other requests. When the low speed bus is free, the highest priority pending requestor is provided access to the low speed bus on a priority basis over all then-current requestors.
