Title: Correcting method for data used for control operation of vehicular clutch
Inventor: KOHNO HIROMI
IPC: F16D48/02
Filed: 1991-06-10
Abstract: ABSTRACT OF THE DISCLOSURE           In a method for correcting clutch data used for controlling the operation of a friction clutch connected with an electronically controlled transmission system, the  clutch data includes meet position data stored in a memory and the stored meet position data is compared with a first learned meet position data obtained after power is applied to the transmission system.  The old data stored in the memory is replaced with the first learned meet position data when the difference between the old data and the first learned meet position data is greater than a prescribed value.  The old data is corrected by the use of the old data and the learned data when the difference is not greater than the prescribed value even if the learned data is the first learned meet position data.

Patent CA-2057499-A1 (CA)
Inventor: GROENENDAAL JOHN C JR
IPC: F01D9/04
Filed: 1991-12-09
Abstract: 56,037 ABSTRACT A steam turbine is disclosed which eliminates the transfer of thermal deformation from the inner cylinder to the stationary blade assemblies.  A dual plane bolted connection and a free floating tongue and groove interface formed between the outer ring of the stationary blade assemblies and the turbine inner cylinder provide the clearance necessary to remove the deformation associated with the stationary blade assemblies, while supporting them within the turbine assembly.  The outer ring of the stationary blade assemblies may either be formed as an integral component of formed from two sections which are then welded together.  The present invention also permits the rotational blades of the turbine to be placed in close proximity to the outer ring of the stationary blade assemblies and the positioning of the flow guide on the outer ring, since the deformations due to the thermal deformation of the inner cylinder are now isolated and the deformation due to the stationary blade assemblies is eliminated. As a result, the dimensions of these components are more precisely controlled and result in a more efficient and economical steam turbine.

Title: Cellular telephone zone system
Inventor: VENDETTI DINO J
IPC: G01S5/10
Filed: 1992-11-25
Abstract: CELLULAR TELEPHONE ZONE SYSTEM        Abstract of the Disclosure Disclosed is a system for marking a plurality of zones within a cellular service area. A plurality of marker transmitters disposed throughout a cellular area transmit a zone identification signal to a mobile or portable cellular receiver. Each zone identification signal is transmitted in a radio frequency coverage area that is substantially coincident with the boundary of a zone. The mobile unit attempts to receive the zone identification signal in order to determine whether it is in the zone. If the mobile unit has determined it is in a zone, it transmits a signal on a reverse control channel to a cell site transceiver that in turn transmits a signal to a mobile telephone switching once. The mobile telephone switching office then can adjust the rate charged on a telephone call made by a user of the mobile unit based on the unit's location within the zone. The marker transmitters are programmed to transmit the zone identification signal during a predefined time slot so that more than one marker transmitter may simultaneously transmit the zone identification signal, thereby increasing the area in which the zone identification signal can be received by the mobile unit. In order to reduce the area in which a zone identification signal may be received by a mobile unit, the marker transmitters may transmit a jamming signal at the same time as the zone identification signal is transmitted.
