Abstract: Disclosed herein are  Streptococcus salivarius subsp. thermophilus  and variants thereof capable of producing an antibacterial substance which is a peptide or protein or a conjugate thereof, the antibacterial substance produced by the bacteria, and processes for producing fermented milk by using any one of the bacteria as a starter. The lactic acid bacteria produce the antibacterial substance, so that use of any one of the lactic acid bacteria as a starter for fermented milk inhibits growth of another lactic-acid-forming lactic acid bacteria also used as a starter owing to the antibacterial substance produced during fermentation. It is therefore possible to suppress the formation of the acid during storage or transportation of fermented milk, thereby making it possible to prevent taste and flavor variations and quality deterioration of the product.

Abstract: A high strength dimpled sheet structure and a method and apparatus of making that structure. A pair of opposed dies having a plurality of upstanding, spaced fingers are provided with the pins of one die spaced between the pins of the opposite die. A sheet of resin precursor impregnated knit fiber material is placed between the dies which are brought together to form a pattern of alternately opposite dimples in the sheet. The resin is cured to at least a shape retaining state and the dimpled sheet is removed from the die assembly. The resin can be either fully cured in the die assembly or after removal from the die assembly. A variety of dimple patterns may be produced by tilting the dies before bringing them together and by varying the height of the fingers in selected areas. Face sheets may be bonded to the dimpled sheet to produce a flat structural panel. The dimpled sheet may be coated with a foam layer, or the spaces between the dimpled sheet and face sheets may be filled with foam. The dimpled sheet in any of these configurations has high strength and is easily manufactured in inexpensive tooling.

Abstract: In a method of monitoring the concentration of a gaseous component in a space which is sealed from the environment and in which an atmosphere of a specific composition is maintained, the actual value of the concentration is monitored by a sensor and when a limit value is reached, an appropriate proportion of the gaseous component is injected in the space. The invention is to improve the method in such a way that calibration of the sensors can be discontinued or has at least to be carried out at such long intervals in time that any impedance of the working activity is insignificant with the appliances equipped in this way. For this purpose, the sensor (6) is subjected to a self-calibration by injecting an initial start concentration into the space (2) and this concentration is passed by the sensor (6) to a measured-value processing unit (10) as the set-point value. The unit (10) uses this to determine an upper limit or a lower limit. If the measured value reaches, or exceeds or drops below, respectively, these limits, an additional injection (lower limit) or a dilution with inert gas (upper limit) is carried out. <IMAGE>

Abstract: A method for forming integrated circuit structures includes the formation of high-value resistive elements and low resistance interconnect in a single polycrystalline layer. In one embodiment, interconnect regions of the polycrystalline silicon layer are masked, and resistive element regions are partially oxidized to reduce the thickness of the polycrystalline layer in such regions. Resistivity of the interconnect regions may then be reduced by implanting a high level of impurities in them, or by forming a refractory metal silicide layer over the interconnect regions. The oxide formed over the resistive elements during the oxidation thereof protects them from either of the following process steps, so that no masking is required. In an alternative embodiment, silicidation of the interconnect regions of the polycrystalline silicon layer may be performed without the prior local oxidations of the resistive element regions.

Abstract: A printing machine, such as a copier or a printer, is provided with an electrophotographic engine cartridge including a toner cartridge (24), a rotatable photoconductor drum (20), and a specially designed magnetic brush developer module (22). The developer module utilizes a rotating magnetic roller (40), disposed in a developer sump (28), to transport a toner carrier developer material (52) toward the rotating drum onto which the toner portion of the transported developer is electrically transferred. The development module is operated in a unique closed loop fashion by the action of a specially designed blade member (56) which strips away the toner-depleted developer (52a) from the roller and causes it to enter a recycling well (58). The depleted developer (52a) is transferred from the recycling well into the developer sump (28) wherein it is mixed with toner entering the sump from the toner cartridge, and then re-applied, in the form of reconstituted developer, to the magnetic roller for subsequent toner transfer to the rotating drum.
