Filed: 1994-09-13
Abstract: A dry etching method for a conductive material layer is disclosed. The dry etching method has the steps of: forming an oxygen-containing antireflection film (6) on a surface of a conductive material layer (5); forming a patterned mask layer (7) on the antireflection film; forming a sidewall protection film (8a) on a sidewall of the mask layer; and etching the conductive material layer (5) using the mask layer having the sidewall protection film formed thereon. The sidewall protection film (8a) is formed after the antireflection film is patterned using the mask layer. The antireflection film (6) is patterned after the sidewall protection film is formed, with the sidewall protection film left on the sidewall of the antireflection film. The sidewall protection film (8a) is formed by using at least one of sulfur based compound and sulfur nitride based compound. The antireflection film (6) is composed of an SiON based material. The conductive material layer (5) is composed of a material selected from the group consisting of a polycide film, an Al based alloy material layer, a Cu based alloy material layer and a refractory metal layer. The conductive material layer (5) is formed on a semiconductor substrate having an insulating film formed on a surface thereof. The conductive material layer is formed on an insulating film having a barrier metal layer formed on a surface thereof.

Abstract: A system controller (32) reacts to conditions that may arise in a plurality of discrete chiller units (10, 12, 14) all individually controlled by dedicated control units (26, 28, 30). The system controller (32) reacts to temperature conditions of the coolant when it enters and when it leaves the chiller units (10, 12, 14). The system controller (32) normally supervises the manner in which the chillers (10, 12, 14) are allowed to individually increase or decrease chilling capacity, and overrides this control when the coolant entering the chiller units (10, 12, 14) drops below a threshold value. The chilling capacity of all running chiller units (10, 12, 14) is decreased when this latter condition occurs.

Abstract: A damper (80) is provided for controlling the flow of conditioned air supplied through a supply duct to a conditioned space. The damper includes a support housing (95) which defines a flow passage which communicates the supply duct with the conditioned space. A plurality of damper blades (110) are mounted within the support housing (95) for pivotal movement about respective spaced apart parallel axes. A blade link (120) interconnects the damper blades (110) in a ganged relation so that a common pivoted orientation of the damper blades (110) is determined by the position of the blade link (120). Means are provided for selectively exerting a force on the blade link (120) which will move the link between first and second positions to respectively decrease or increase the flow of air through the damper (80). Means are provided which allows the blade link (120) to move toward the second position (maximum flow) in response to a force imparted on the damper blades (110) by a build-up of pressure in the supply duct. Under such circumstances the force imparted upon the damper blades is sufficient to overcome the force exerted on the blade link to move the link toward the first position (flow substantially blocked).

Abstract: A method of making a well-compacted mold by using a vacuum air flow is provided. In the method, molding sand (5) is fed into a space defined by a pattern plate (2) and a flask (3) mounted on the pattern plate (2), and the space is enclosed at the upper part of the flask (3) by a cover (6). The air in the enclosed space is evacuated to reduce the air pressure between the grains of the molding sand in the enclosed space to 1 Torr to 150 Torr, and then air is introduced into the enclosed space from the upper part of the space so that the pressure in the space can increase at the rate of 15 atm/s to compress the molding sand (5). The method eliminates the need for vent holes and enables the mold to be crack-free since the air flow is not reflected.

Abstract: A thick (10 to 60 micron) photo-lacquer layer is applied to a semiconductor wafer (1) and formed, by photo-lithography, into cylinder-form). This is heated so that the lacquer cylinder melts to form a spherical dome lens structure which is further hardened. Using a plasma the semiconductor wafer and the photo-lacquer lens structure are etched away at precisely the same rate so an identically shaped profile is formed in the surface of the semiconductor. An anti-reflective, compensating layer (3), metal layer (4) and solder-fixing contacts (5) are then added.

Abstract: A system for analyzing and estimating average transit delay and high percentiles of delay in a packet network (10) uses detailed packet switch measurements (30) that are normally stored in a network database for maintenance and engineering purposes. The system randomly selects source (12) and destination (14) points and samples the stored maintenance measurements (30) for network circuit elements located between the randomly selected source and destination points. These sampled measurements are transmitted to the system processor via electronic mail and the system generates a single server queuing model (40) to determine average and variance of delay for each component. A network-of-queues model is then constructed to determine the end-to-end average delay and end-to-end variance of delay. An Erlang probability distribution is then applied to these end-to-end values to provide statistics of packet transit delay in the packet network (10).

Abstract: An inflammatory cytokine is disclosed which has been isolated 
from cells that have been incubated with a stimulator material. 
The inflammatory cytokine comprises a protein that is capable of 
binding to heparin, inducing localized inflammation characterized 
by polymorphonuclear cell infiltration when administered 
subcutaneously and inducing in vitro polymorphonuclear cell 
chemokinesis, while lacking the ability to suppress the activity 
of the anabolic enzyme lipoprotein lipase, cause the cytotoxicity 
of cachectin/TNF-sensitive cells, stimulate the blastogenesis of 
endotoxin-resistant C3H/HeJ thymocytes, or induce the production 
of cachectin/TNF by primary thioglycollate-elicited mouse 
macrophage cells. A particular inflammatory cytokine MIP-1 has 
been isolated and has been found to comprise a peptide doublet 
of similar molecular weights of about 8,000 daltons, and to show 
a pI of about 4.6. The doublet has been resolved into its 
component peptides, MIP-1α and MIP-1β for which distinct cDNA's 
have been cloned and sequenced.

Abstract: An electrostatic potential in a vacuum in the vicinity of a focused electron beam (32) of a direct wave formed on an optical axis of a back focal plane of an objective lens 28 used in an electron microscope can be externally controlled. The electrostatic potential is controlled by supplying electric potential to a ring-shaped electrode (8) from the outside. The outer sides of the electrode (8) are interposed between insulators and conductors so as to shield the electrostatic potential against the outer side of a ring, whereby a phase shift is supplied only to the electron beam (32) that passes through the inside of the ring. A phase-contrast electron microscope can thus be realised which includes a phase plate (100) corresponding to an electron beam, and which permits observing a phase object with contrast. <IMAGE>
