Abstract: A process is provided for the destruction of organohalogen compounds, such as methyl chloride, chloroform, carbon tetrachloride, etc., by mixing the organohalogen compounds with a heated carrier gas, such as nitrogen, argon or air, and either steam or water to form a mixture; supplying the mixture to a catalyst, such as titanium oxide/tungsten oxide, to decompose the organohalogen compounds into halogens and hydrogen halides, such as chlorine, hydrochloric acid, fluorine and hydrofluoric acid; conducting the halogen and hydrogen halide contaminated gas through a bent path, created by a baffle that prevents the entry of mist or droplets into the catalyst chamber, into a cooling section where the halogen and hydrogen halide contaminated gas is sprayed with water to cool the gas to a temperature low enough to prevent the formation of dioxines. An alkaline agent, such as sodium hydroxide, can be added to the cooling water to neutralize the halides and hydrogen halides.

Abstract: In a data processing system in which main and sub disk storage devices are under the control of individual each disk control devices, the write processing time is reduced by selectively sending data according to the command-chaining time between main and sub disk control devices. A section for judging cable length and function of the sub disk control device 36 estimates command-chaining time between a pair of main and sub disk storage devices. The channel command analyzing section 31 estimates the number of records to be transferred and the length of a record using a LOCATE RECORD command. The command judgment section for the sub disk control device 32 optimizes the command-chain to be issued to the sub disk control device using the above-mentioned information. Then, the section for issuing command to the sub disk control device 35 issues the optimized command chain. Thus, a shorter transmission time is realized by either sending individual records or an entire track of data.

Abstract: An electronic device is solder bonded properly without using fluxes nor precise positioning with respect to a substrate. A bond pad with a size about twice the size of terminal pad of the electronic device is formed in a region on the substrate where the electronic device is to be mounted. After placing the electronic device of the substrate surface, the whole unit is heated in a nitrogen atmosphere to melt a bump formed on the terminal pad of the electronic device. The molten solder wets and spreads over the bond pads formed on the substrate, thereby establishing reflow soldering between the bond pads and the terminal pads. The position of the electronic device with respect to the substrate is spontaneously corrected due to a self-alignment function induced by wetting and spreading of the molten solder over the bond pad of the substrate.

Abstract: A negative pressure flying head slider includes an air bearing surface of a substantially rectangular shape disposed in opposed relation to a rotating magnetic disk. One side rail of the slider is adapted to be located at an outer periphery-side of the magnetic disk when the slider is mounted on a magnetic disk device, and has an inflow-side side rail portion which is disposed at an air inflow end-side of the slider, extending generally parallel to the longitudinal direction of the slider, and an outflow-side side rail portion which is disposed at an air outflow end-side of the slider, extending in a direction of a yaw angle. The angle of the outflow-side side rail portion with respect to the inflow-side side rail portion is greater than the maximum value of an absolute value of the yaw angle. The slider further includes a recess defined by a cross rail and the side rails, and a slit formed in the cross rail to permit the recess to communicate with the air inflow end of the slider.

Abstract: A user of services is enabled to utilize a highly value-added service employing secret data of the user without presenting the data to the service provider side. In a system in which a server is coupled with a client via a communication network, the client inputs and sends a service identifier to the server, receives a program to execute the service from the server, inputs secret data as client controlled data from an input device and sends a server control data request to the server, and then receives the requested data from the server. The input data is irreversibly processed by use of the program and received data such that the client sends results of the process to an expert on the server side to receive an advice of the expert. By referring to the advice, the service user inputs evaluation of the outputted results. The steps beginning at the data request input are repeatedly conducted until the evaluation becomes satisfactory, thereby transmitting the process results to the server.

Abstract: A method for preparing carboxylic acids by carbonylating a reagent, particularly an alcohol, in the presence of a rhodium catalyst. According to the method, the liquid phase reaction is carried out in a first zone in the presence of a rhodium catalyst, and the resulting reaction mixture is partially vaporised in a second zone. The vaporised fraction containing the carboxylic acid is later purified and the unvaporised liquid fraction containing the catalyst is recirculated to the first zone. The method is charactracterised in that said unvaporised fraction is contacted with carbon monoxide in such a way that this compound is not returned to the second zone.

Abstract: A surgical lighthead having a stacked elliptical reflector (20) directs light from a lamp (10) to an illumination zone (Y) without the need for a refractor to redirect the reflected light. The reflector is formed of at least three annular reflector segments (22, 24, 26) stacked on top of each other to form a continuous reflector surface. Each of the reflector segments has a longitudinal cross section of a different conical shape such as elliptical or parabolic for directing the light to a different portion of the illumination plane. The stacked elliptical reflector provides the benefits of reduction of the image of the filament in the light field and reduction of shadowing due to objects passing between the lighthead and the illumination plane.

Abstract: A fiber-optic imaging probe is disclosed for use in dynamic light scattering applications. The probe includes two monomode optical fibers and two GRIN lenses to form a pair of identical fiber-lens combinations. Each fiber is positioned off the optical axis of its associated lens. Further, the optical fibers are placed at an image plane of the lenses. The fiber-lens combinations are parallel to and mirror images of each other. The first fiber-lens combination projects a tightly focused spot of light into a scattering volume containing suspended or dispersed microscopic particles, or biological or live tissues. The second fiber-lens combination collects the light which is scattered from the particles in the scattering volume and conveys it to a photo detector and autocorrelator for analysis. The probe minimizes the scattering volume by advantageously using imaging principles of lenses. Further, the probe optimizes sensitivity and spatial coherence.

Abstract: A method of manufacturing angiographic catheters comprises providing a length of elastomeric tube of a predetermined outer diameter and braiding multiple strands of wire wrapping about its exterior. A plastic bonding agent is extruded onto the entire length of the wire wrapping to bond the strands to each other. Thereafter, the wire wrapping is ground away at predetermined spaced locations along the length of the elastomeric tube to provide a series of wire wrapped sections joined by non-wrapped sections. An elastomer layer is disposed over both the wire wrapped sections and the non-wrapped sections throughout the length thereof. Subsequently, the coated length is severed into pieces with the pieces each constituting unitary construction including a wire wrapped section that forms a catheter body and a non-wrapped section joined to at least one end thereof to constitute a flexible catheter tip.

Abstract: In order to manufacture a semiconductor device of high performance a small-sized transfer arm mechanism, capable of retaining a predetermined transfer stroke, is put to practical use without any increase in the height of the arm mechanism. The transfer arm includes arcuate portions having center axes different from each other, and restraint generating means for generating restraints in directions where the individual center axes are attracted. This way, a plurality of arms are joined by joints having a structure for transmitting rolling motions to the arcuate portions contacting each other to thereby control the drive shaft of the arcuate portions rotationally and thereby move the arms. This transfer arm mechanism is used in various environments including semiconductor manufacturing, such as DRAMs (dynamic random access memory).

Abstract: The present invention is directed to the isolation and purification of an L1-like molecule (i.e. L1CAM) from human brain. It has been found that the isolated L1CAM molecule supports neurite growth in vitro. Applicants have also cloned and sequenced the entire coding region of human L1CAM, and found that it shows a very high degree of homology to mouse L1cam with 92% identity at the amino acid level. This similarity suggest that L1CAM is an important molecule in normal human nervous system development and nerve regeneration. Overall, there is substantially less homology to chick Ng-CAM; they are 40% identical at the amino acid level but many regions are highly conserved. Comparison of the sequences from human, mouse, chick and Drosophila, indicates that the L1 immunoglobulin domain 2 and fibronectin type III domain 2 are strongly conserved and thus are likely functionally important.

Abstract: A magnetic recording/reproducing device has an inductive write element provided with a coil and magnetic cores for recording information on a medium, a magnetoresistive read element for transducing a change in a magnetic field leaking from a medium, on which information is recorded, into an electrical signal, a detector for detecting an output signal of the read element, a bias field applying unit for applying a bias field to the read element, and a recording/reproducing operation controller for reproducing information based on an output signal from the read element and for controlling the recording current applying unit based on an inputted signal to record information. The recording/reproducing operation control unit has a stabilizing unit for controlling the bias field applying unit to make an absolute value of the bias field in a state where a magnetic field leaking from the medium is applied to the read element larger than that during a normal reproducing operation.

Abstract: To form in a batch manner a thin-film wiring pattern in high precision over an entire region of a ceramics multilayer wiring board containing distortion and deformation, a correction amount of the ceramics multilayer wiring board (rotation angle and movement amount of position of this ceramics multilayer wiring board) is calculated in a computer by applying, for instance, the least squares method to positional coordinate values of each of the LSI mounting areas of the ceramics multilayer board and also to positional coordinate values corresponding thereto on a photomask. A support apparatus for supporting the multilayer wiring board is controlled based upon the calculated correction amount, so that the multilayer wiring board can be aligned with respect to the photomask.
