Title: Regenerative braking circuit utilizing separately excited motor
Inventor: LAMBERT JOE CHESTER
IPC: H02P7/00
Filed: 1996-03-25
Abstract: A separately excited DC motor is arranged to provide operation in a smooth, continuous electrical retarding mode. A series contactor 24 connects the motor armature 10 to a DC power source 14 and is controlled so as to immediately open upon sensing of a need for electrical braking. Concurrently, power to the motor is reversed by H-switch 34a-34d so that no additional changes are required to brake to zero speed. When the speed falls to below a value necessary to maintain the armature voltage above the DC source voltage, the armature is cyclically short-circuited by a switch 26 to boost armature current so that when the short-circuit is removed, the armature reactance forces current to continue for regeneration. The braking operation commences when a microcomputer 44 senses an accelerator 46 has returned to a rest position, a direction switch 48 has been shifted to a neutral position or a brake switch 54 has been actuated.

Title: Linking air conditioning with evaporation gas intercepting system for vehicle
Inventor: SUZUKI YASUFUMI
IPC: F02M25/08
Filed: 1997-01-23
Abstract: An evaporation gas intercepting system prevents the entrance of evaporation gas leaked from a canister 36 into a passenger compartment of a vehicle having an air conditioning system in which an outside air intake or inside air circulation can be selected. An engine control unit calculates a fuel injection quantity on the basis of parameters indicating the operating condition of an engine and correction coefficients, and a feedback correction quantity for correcting the fuel injection quantity on the basis of the output signal of an air-fuel ratio detector (oxygen sensor). If an excessive quantity of the evaporation gas is supplied to the engine such that the fuel injection quantity cannot properly be corrected by the feedback correction quantity, and the engine control unit carries out an evaporation correcting operation by using an evaporation correction, an air conditioning system control unit sets the automotive air conditioning system forcibly for an inside air circulation mode to prevent the entrance of the evaporation gas bearing a fuel odour and leaked from the canister into the passenger compartment.

Title: Coupling between a twisted rod and a torsion spring of a spiral counterbalance
Inventor: NEWTON WILLIAM P
IPC: E05D13/00
Filed: 1997-07-08
Abstract: A coupling between a twisted rod 12 and a torsion spring 13 of a spiral counterbalance 10 has been found to be subject to deformation against the twisted rod 12 from compressive force of the grip of the terminal convolutions 23 of the torsion spring 13. This problem is solved by using a metal sleeve or cylinder 27 at the rotation transmission sleeve 26 of the coupling to resist the compressive force and prevent deformation, so that the twisted rod can move freely within the coupling. The metal sleeve 27 may be within the transmission sleeve 26, as in figure 1, or outside it (transmission sleeve 36, figure 2). This solution also allows the use of a stronger torsion spring to exert a larger counterbalance force.

Abstract: A variable phase coupling is for connecting a crankshaft, via a gear 20, to a camshaft 12. The coupling comprises a drive member 18 carrying the gear 20 and having a cylindrical surface with helical grooves (40, Fig.2) of a first pitch. A driven member 14 is connected to the camshaft 12 and has a cylindrical surface with helical grooves (26, Fig.2) of a different pitch facing towards the grooves in the drive member 18. Balls 28,34 engaged in the two helical grooves serve to couple the drive and driven members for rotation with one another. An intermediate member 16 is disposed between the drive and driven members in contact with the balls, and means 56 are provided for displacing the intermediate member 16 relative to the drive and driven members. The displacement of the intermediate member 16 serves to move the balls relative to the helical grooves in the drive and driven members so as to vary the phase between the drive and driven members.
