Abstract: A lift-off process for patterning bottom shields used in thin film magnetic re­cording heads. The lift-off process comprises the steps of depositing a first layer of resist material (22) on a substrate (20) and hard baking the resist material (22). A transfer layer (24) is deposited over the first layer of resist material (22) and a second layer of resist material (26) is deposited on top of the transfer layer (24). The second layer of resist material (24) is then patterned and developed. The patterned structure is then etched to form a mask structure wherein the transfer layer (24) overhangs the first layer of resist material (22). An adhesion layer (30) and an amorphous magnetic alloy material (32) are then sequentially deposited on the exposed surface of the sub­strate (20). The amorphous magnetic alloy material (32) is sputter deposited at a pressure of about about 3.4 mT, a condition that resists the stress in the amorphous alloy material to less than 10⁹ dynes per square centimeter. Low stress is required to preserve the integrity of the mask structure. The mask layers and unwanted amor­phous alloy material (32) are removed using ultrasonic agitation in acetone. This process results in a shield pattern having tapered sidewalls which enhance the reli­ability of subsequently deposited conductor metallization.

Abstract: A control circuit is provided for the output of a high frequency inverter of the type having an output transformer with a core, primary windings and a secondary winding with two sections for creating a first secondary current pulse of electrical current in one section when the primary windings magnetizes the core and a second secondary current pulse in the other of the secondary sections when the primary windings remagnetizes the core. By alternating switch means for passing current through the primaries to magnetize and remagnetize the core at a preselected rate the output current pulses are provided by the two sections of secondary windings. The control circuit of the present invention involves a modification of the output transformer secondary stage. A first auxiliary winding is connected to one of the secondary sections to create an auxiliary current pulse as the core of the transformer is magnetized. A means is then employed for limiting this auxiliary current pulse and for adding the limited auxiliary current pulse to the first secondary pulse created by the secondary section to which the auxiliary winding is connected. In a like manner, a second auxiliary winding is connected to the other of the secondary sections to create a second auxiliary current pulse as the core is remagnetized. Means are provided for limiting the second auxiliary current pulse and for adding the second auxiliary current pulse to the second secondary current pulse from the secondary winding. Addition of limited current pulses to secondary current pulses created by the inverter provides a maximum output voltage which is higher than the maximum output voltage normally available while conserving primary current under higher output current conditions.

Abstract: A method for determining the values of pixels in a resulting image having a greater number of pixels than an original image describes a technique for calculating the values of the new pixels in the resulting image. A rectangular region centered on a junction of four pixels in the original image is used as the basis for calculation. This rectangular region contains one-fourth of the adjacent original pixels, and is divided into 8 triangular regions. All of the pixels of the resulting image within a triangular region are given the same color, and the color assigned to the pixels in each such triangular region is a function of the colors of the four adjacent pixels in the original image.

Abstract: A so-called Ziegler catalyst composed of a titanium halide-containing solid ingredient and an organoaluminum compound for the polymerization of olefins can be imparted with greatly improved storage stability by first subjecting the catalytic composition to a pre-polymerization treatment and then to a contacting treatment with carbon dioxide and/or carbon monoxide. The catalytic activity is almost unchanged even after storage of the stabilized catalyst for 90 days or longer in nitrogen gas. The stabilized catalyst can also be used advantageously in a continuous process for the polymerization of propylene by continuously introducing the monomer carrying the catalyst because blocking of inlet pipe lines with polymer formed in-line is avoided when using the stabilized catalyst.

Abstract: A nuclear spectroscopy method and apparatus for the analysis of a signal comprising pulses representative of random nuclear events, and for the determination of the dead time, including counting and recording, versus time, the accumulated counts of the pile-up events (PU), i.e. events identified as being characteristic of two or more overlapping events, and the counts of non pile-up events (NPU), for each of successive time intervals of a measurement cycle. Particularly the method includes: forming a preliminary reference plot of the PU count rates versus the NPU count rates; forming an actual plot corresponding to the signal under analysis, of PU count rates versus NPU count rates; and deducing the dead time from comparison between actual and reference plots. In an alternative embodiment, the method allows one to maintain constant the dead time, during the signal analysis, by: establishing a preliminary relationship between dead time and different plots of PU count rates versus NPU count rates; establishing a preliminary relationship between the plots and a functioning parameter; establishing a reference plot corresponding to an imposed dead time; establishing an actual plot; comparing the actual and reference plots; and modifying the functioning parameter so as to bring the respective actual and reference plots in compliance.
