Abstract: In a control system for controlling a gear ratio of a multi-step geared or continuously variable automatic transmission, the driver's intention to decelerate (DEC) is inferred by carrying out a first fuzzy reasoning (S12) using a degree of throttle opening or the like and then the target gear ratio is determined by carrying out a second fuzzy reasoning (S16) using parameters including the inferred driver's intention to decelerate. The first fuzzy reasoning (S12) is carried out using fuzzy production rules classified by operating conditions such as the road profile and the vehicle speed. The inferred driver's intention to decelerate (DEC) may be cancelled if braking is discontinued. Thus the control system ascertains the intention of the driver and it is thus possible to achieve sophisticated shift scheduling well matched to the sensibilities of the driver.

Abstract: An improved system for tuning process control equipment applies a load change of amplitude δq to the process to effect a change in it and, therefore, in the controlled variable. Monitoring the response of the controller to that change, the system identifies an observed overshoot, OVS o , in the manipulated variable signal. From that overshoot signal and a predetermined theoretical overshoot signal, OVS τ , the system generates an optimum gain, K opt , as a function of the mathematical expression           K       opt            = K * (1 + OVS       τ           ) / (1 + OVS       o       )           
 where, 
   K is the current gain of the automatic control subsection,

Abstract: Taxol-type compounds are produced by coupling baccatin III-type compounds (and related alcohols) with chemoenzymatically produced β-lactam enantiomers. The β-lactam enantiomers are produced from racemic starting substituted β-lactams through lipase contacting to achieve either enantioselective hydrolysis or enantioselective transesterification (the latter with an added 1-substituted ethenyl acetate). Preferred β-lactam enantiomers are coupled to the C-13 hydroxyl of the starting baccatin III-type compounds which are derived from 10-deacetyl baccatin III. Certain of the β-lactam enantiomers are new as are taxol-type compounds produced by the coupling reaction.

Abstract: Caramel confections which facilitate coating, depositing, molding and baking are prepared from a finely divided solid candy phase dispersed within a continuous fat phase. These products differ from conventional caramel products which are based on sugars and milk protein and typically exhibit a chewy texture but are difficult to mold or to otherwise handle. A powdered caramel brittle material is made by sheeting, cooling and grinding a caramel prepared by cooking aqueous milk solids with sugar to a moisture level of below 6%. Preferably, from 5 to 35% of the powdered caramel brittle is mixed with 30 to 60% granulated sugar, 18 to 30% fat, and 10 to 25% milk solids. The mixture is refined to obtain an average particle size of 0.0004 to 0.0020 inches (about 0.0102 to about 0.0508 mm) mixed with an emulsifying agent and additional vegetable fat, and heated as necessary to reduce the moisture level.

Abstract: The present invention is to generate a binary halftone image by taking full advantage of high resolution dots and low resolution dots. A Laplacian filter is applied to the density data of an original image to determine filtered density data representing spatial frequencies of the original image. A dot selection signal (SEL) for selecting one of the high resolution dots and the low resolution dots is generated based on a comparison between the filtered density data and a threshold data. A dot generator (32) includes a first screen pattern memory (48) for storing a threshold pattern of the low resolution dots and a second screen pattern memory (50) for storing a threshold pattern of the high resolution dots. A selector (52) receives threshold data DTH1 and DTH2 output from the first and the second memory (48) and (50) and selects one of the threshold data DTH1 and DTH2 in response to the dot selection signal (SEL). A comparator (54) compares image data D IM  with the selected threshold data and generates a dot signal Sd to record a binary halftone image.

Abstract: A process for selectively removing a porous silicon oxide layer from a substrate having a portion thereon with an exposed dense silicon oxide which is to be retained on the substrate, the porous silicon oxide layer containing absorbed moisture therein, the process comprising : 
   introducing the substrate to a flowing anhydrous gaseous environment consisting of anhydrous inert gas; 
   adding anhydrous hydrogen fluoride gas to the gaseous environment for a pulse time which is at most only slightly longer than that required to initiate etching of the dense silicon oxide; 
   flushing the gaseous environment with anhydrous inert gas for a time sufficient to remove said hydrogen fluoride and water vapor generated by the etching of the porous oxide; and, 
   repeating said adding and flushing steps until said porous oxide layer has been removed. 
     The process has particular application in manufacturing of capacitors on microelectronic devices for etching out BP TEOS or other such doped porous oxides contained within an open polysilicon structure built on a portion of a blanket layer of dense silicon oxide, such as TEOS. The process permits extremely highly selective removal of porous silicon oxides, especially doped oxides, relative to dense silicon oxides in a gentle manner. In particular, the process provides selectivity for removal of BP TEOS over removal of TEOS of greater than 50:1 based upon oxide layer thickness removed.
