Abstract: A process of degassing and decarbonizing is directed to a process for performing vacuum degassing non-deoxidized or slightly deoxidized molten steel utilizing RH process or DH process. The process includes blowing of oxygen or oxygen containing gas toward the surface of the molten steel in a vacuum chamber for promoting decarbonizing reaction. The process further includes a step of combustioning of CO gas in the vicinity of the surface of the molten metal at a timing, in which concentration of (CO + CO₂) in an exhaust gas is higher than or equal to 5% and a a ratio of CO₂ versus (CO + CO₂) in the exhaust gas is approximately 30%. Heat generated by combustioning of CO gas is utilized for compensating temperature drop of the molten steel.

Abstract: A lactulose syrup suitable for use in the production of foods and drugs is produced by the alkali isomerization of lactose. Elimination of mono­saccharides formed in the reaction mixture, such as galactose, is conducted by passing the reaction mixture through a column packed with beads of a strongly-acidic chromatographic cation-exchange resin, said beads having substantially the same crosslinking degree, and then collecting lactulose-containing eluate fractions. This process is suitable for the industrial production of a high-purity lactulose syrup.

Abstract: In order to achieve optimum applicational properties of aqueous surfactant solutions, thickeners are added to these solutions. The known thickeners must be added to the surfactant systems in high concentrations which may be, for example in the case of electrolyte thickeners, so high that skin irritations may occur. The novel thickener mixtures do not have these disadvantages. Thickeners for surfactants and surfactant systems are proposed which comprise a mixture of a nonionic surfactant having an HLB value of from 4 to 11 with a polymer. The nonionic surfactant used is a compound of the general formula R-(BO)e(CH2CH2O)f-X and the polymer used is a compound of the general formula x[R<1>-(CH2CH2O)b (BOa]-A-[(BO)c (CH2CH2O)d-R<2>]y. These mixtures do not have the abovementioned disadvantages. A synergistic thickening effect occurs. These thickener mixtures are used in concentrations of only from 0.05 to 10% in surfactants and surfactant systems.

Abstract: A method has been developed for providing tub regions with various resistivities in a dielectrically isolated (DI) structure. The starting substrate material is etched to expose the locations designated for a resistivity modification, and epitaxial material of the modified resistivity value is used to fill the exposed tubs. The remainder of the fabrication process follows conventional DI fabrication techniques. The procedure may simply be used to create a DI structure containing both n-type and p-type tub regions. The idea may also be extended, however, to providing separate tubs with, for example, n+ resistivity, n- resistivity, p- resistivity and p+ resistivity, all within the same DI structure.

Abstract: An improved circuit for controlling the output power level of a radio frequency (RF) amplifier is disclosed. The circuit samples the output of an RF amplifier (10). The sample is amplitude modulated at a preselected modulation frequency and is passed to a detector (18). In response to the amplitude modulated signal, the detector produces a signal whose amplitude is indicative of the RF amplifier's output power and whose frequency is the modulation frequency. The amplitude of the signal produced by the detector (18) is then compared to a reference amplitude and the difference (error signal) is used to control the gain of the RF amplifier (10).

Abstract: The present invention is a computer system which can perform master unit controlled memory accesses at a first rate, DMA controlled operations at a second rate and burst operations of both types at a higher third rate. The burst operation is set up by performing a standard access cycle, thus setting up the dynamic random access memory row address, and then performing a series of fast, column address-only accesses to the same page of memory. The fast mode must be exited to a standard rate access whenever a page boundary is crossed, with burst operations recommencing thereafter. Wait states can be inserted in all type operations. Thirty-two bit master units can downshift or step down to 16 bit operation to respond to 16 bit burstable responding units. Timing diagrams and controller state machines are disclosed.

Abstract: The preparation of highly densified ceramic bodies by the sintering of certain organopolysiloxanes filled with silicon carbide powders and metal-containing sintering aids is described. Such highly densified ceramic bodies can be prepared by either a pressureless sintering process or a hot press sintering process. The compositions of this invention can be formed into desired shapes and then sintered to form ceramic, shaped bodies with high densities. One advantage of the present invention is that the green bodies have relative high strengths and thus can be easily handled and, if desired, machined before sintered. The organopolysiloxanes useful in this invention must yield a ceramic char which contains free or excess carbon in addition to carbon in the form of silicon carbide upon pyrolysis to elevated temperatures.

Abstract: An improved ink jet printhead (10) is disclosed of the type having a plurality of parallel ink flow channels (20) which terminate with an ink droplet emitting nozzle (27), a heating element (34) with a cavitational protective layer thereover located in each channel, and MOS electronic circuitry monolithically integrated within the printhead for applying electrical pulses to the heating elements (34). The pulsed heating elements produce bubbles momentarily on the protective layer of the heating elements which expel ink droplets from the nozzles. The improvement is obtained by providing multi-layer ionic passivation of the MOS electronic circuitry which is exposable to the ink. This is accomplished through the deposition of a multi-layered, thin film insulative coating thereon consisting of a first layer of doped or undoped silicon dioxide having a thickness of 200 Å to 2µm followed by a second layer of plasma nitride having a thickness of 1000 Å to 3 µm. The silicon nitride is etched from the protective layers of the heating elements and electrical contact pads for external connection to electrical power so that the first layer of silicon oxide is exposed, followed by etching of the silicon oxide to remove it from the protective layer and contact pads. Thus, the MOS circuitry is protected from mobile ions in the ink while the cost effective fabrication of a printhead is maintained. In an alternate embodiment, the multi-layered ionic passivation comprises three thin film layers comprising polyimide interfacing with the ink, followed by silicon nitride, and doped or undoped silicon dioxide directly interfacing with the metallization.
