Title: Four-wheel drive vehicle
Inventor: YAKOU TAKAYUKI
IPC: B60K23/04
Filed: 1998-01-13
Abstract: A rear differential in a four-wheel drive vehicle includes a left and right clutches adapted to distribute a driving force transmitted from front wheels through a propeller shaft to left and right rear wheels. If the engagement of the left and right clutches is released, only the front wheels are driven and in this manner, the vehicle is brought into a front wheel-drive state. If the left and right clutches are brought into their engaged states, both of the front wheels and the rear wheels are driven and in this manner, the vehicle is brought into a four-wheel drive state. By changing the engagement forces of the left and right clutches, different driving forces can be distributed to the left and right rear wheels. In addition, when a driver operates a differential lock switch, the left and right clutches, are brought into their engaged states with the maximum engagement force, thereby integrally coupling the propeller shaft to the left and right rear wheels to provide a differential-locked state. Thus, a differential lock mechanism can be provided to the differential in a simple structure.

Abstract: The present invention relates to a method and apparatus for grinding crankpins of a crankshaft.  The method is comprised of the  steps  of  mounting  the  crankshaft  between centres;  and attaching radially outer regions of the flange to a rotational drive to rotate the crankshaft about  its main axis,  via a coupling  which  is  torsionally  rigid  in  a  plane  generally perpendicular to the axis of rotation of the crankshaft but which is  readily  deformable  in  other  planes  to  accommodate misalignment.  The method further includes advancing the grinding wheel  to  engage  a  crankpin  region  of  the  crankshaft; and synchronously controlling the position of the grinding wheel whilst the crankshaft is rotated thereby to follow the planetary motion of the crankpin so as to maintain grinding contact between the wheel and the pin.   The apparatus is a grinding machine adapted  to  grind  a  crankpin  region  of  a  crankshaft  by synchronously advancing and retracting the grinding wheel as the crankshaft is rotated so that contact is maintained between grinding wheel and crankpin during grinding of the pin.  This assures that a true cylindrical surface is ground on the pin. The grinding machine is comprised of a drive unit for rotating the crankshaft, and a coupling unit which is torsionally rigid in a plane generally perpendicular to the axis of the crankshaft but  is  readily  deformable  in  other  planes  to  accommodate misalignment, for connecting the drive unit to the crankshaft.

Title: Networked facilities management system
Inventor: RASMUSSEN DAVID E
IPC: H04L12/24
Filed: 1991-01-25
Abstract: A network system having a wide variety of applications and particularly applicable to facilities management systems has multiple levels of software in processing nodes. The levels include a "features" processing level which communicates requests for data to a software object level containing databases of processes and attributes and database managers. The database managers in the software object level operate to provide data to the high level features in the same format. The software object level communicates with a hardware object level which also contains databases and database managers to mask differences between operational hardware units. By categorizing operational units by type, additional units of a known type can be added with only low level hardware object database changes. Adding units of a new type is facilitated by software changes confined to the lower level hardware and software objects, avoiding software changes at high level features. Individual software objects are tailored for typical types of inputs and output devices encountered by facilities management systems. Universal drive circuitry also provides applicability to a broad range of devices.
