Title: Controller for electric motor vehicle
Inventor: ARAI YOSHIHIDE
IPC: H02P23/07
Filed: 1993-09-21
Abstract: PURPOSE:To prevent the generation of a torque hunting when a vehicle speed pulse is used instead of a number-of-revolutions pulse. CONSTITUTION:A latest torque command TN is compared with a previously calculated torque command Told thereby to calculate a torque command change DELTAT in the step 112. The calculated torque command change DELTAT is compared with a threshold value DELTATref, and a torque command T value is limited based on its result in steps 114-120. Since the change of the command T of its output is suppressed, a torque hunting is suppressed. Further, the command T is limited by using a map B having a small maximum output torque TmaxB at the time if using a vehicle speed pulse in the steps 124 and 126. Safety in a high speed range is improved. Further, a current command I or a current value is limited. An element damage is prevented.

Title: Method and apparatus for loading to adjust print head with using magnet
Inventor: KERR ROGER S
IPC: B41J2/475
Filed: 1999-08-23
Abstract: PROBLEM TO BE SOLVED: To precisely conduct a focusing and an angle control of a print head by setting at least one magnet member to a print head holder, arranging an adjusting device so that an attractive magnetic force and a repulsive magnetic force are generated to adjust a position of the head, and applying magnetic load. SOLUTION: A focus-adjusting device for a print head 500 uses a focal micrometer. The micrometer is set flat to a surface of a translation stage member 220 so that an axis is parallel to an axis of the head 500. A head angle- adjusting device executes adjustment with a head angle micrometer. In order to correctly adjust a focal angle, permanent magnets integral with the head 500 in terms of operation are used and a repulsive force of the permanent magnets is used to apply a load to the micrometer. The permanent magnets exert a magnetic 'spring load' to the micrometer by repulsive force generated when the same poles are arranged adjacent to each other.
