The use of anti-friction ball bearings in a unique arrangement does not require the use of lubricating oil from the internal combustion engine lubricating system and permits close coupling of the bearings and a compact turbocharger. A turbocharger bearing housing forms a coolant jacket with an inner bearing engaging portion that has two bearing engagement surfaces engaged with the outer races of two anti-friction bearings whose inner races carry rotating shaft, turbine and compressor of the turbocharger. The anti-friction bearings are, preferably, angular contact ball bearings, and the two bearing engagement surfaces of the bearing housing are closely spaced, providing a turbocharger shaft of minimal length and substantially reducing the thermal expansion of the shaft. The coolant jacket protects the anti-friction bearings from exposure to the extreme heat of the exhaust gas driven turbine, notwithstanding their increased proximity due to the shortened turbocharger shaft. In addition, an external motor-generator may be carried by the compact turbocharger, and its motor may be connected to the turbocharger rotor assembly by a permanent, solid connector and stay connected throughout the entire operating range of the turbocharger. In such assembly, the electronic motor-generator control is mounted on the motor housing and energizes the motor from battery power during the engine acceleration period up to approximately the torque peak speed; thereafter, the control changes to a generator mode when excess energy is available in the engine exhaust gas.

A tone ring of a vehicle anti-lock braking system of the type that is integrated into a disc brake rotor. The tone ring has a protective layer which enables it to withstand the combination of extreme heat and harsh environmental conditions to which it is exposed during operation of the vehicle. The protective layer is applied by thermally spraying a selected one of a plurality of materials, such as a nickel-based alloy, a high-chrome stainless steel, or non-ferrous materials such as an aluminum, copper-based alloys or a ceramic, on teeth of the tone ring, and without causing the protective layer to be deposited on the rotor braking surfaces. The protective layer generally prevents the formation of oxidation and corrosion byproduct layers on the teeth, to thereby maintain sensitivity for detection of teeth movement by the anti-lock braking system sensor during operation of the system.

The invention relates to a method of simultaneously liquefying and saccharifying cirn starch. The method uses an extreme heat-stable amylase maltose with an optimum catalytic reaction temperature of 90-100 DEG C to substitute an Aspergillus niger glucoamylase with an optimum catalytic reaction temperature of 55-65 DEG C. Because the extreme heat-stable amylase maltose has similar optimum catalytic reaction temperature and optimum catalytic reaction pH with a Bacillus licheniformis alpha-amylase, the extreme heat-stable amylase maltose, together with Bacillus licheniformis alpha-amylase, can be added into a corn starch slurry preheated to 90-100 DEG C and with a concentration of 10-30 % (w/v), and then kept warm for a while at a same temperature to obtain the corn starch syrup with a total yield of glucose, maltose and isomaltose being more than 110 % (w/w). The method overcomes a problem that in traditional production technology of corn starch syrup, the Bacillus licheniformis alpha-amylase is firstly used to liquefy the corn starch under 90-100 DEG C and a pH of 5.0-6.0, and then the Aspergillus niger glucoamylase is used to saccharify the corn starch under 55-65 DEG C and a pH of 4.2-4.5, and operation steps of adjusting temperature and pH are thus needed, thereby improving production speed of the starch sugar.
