Title: Direct torque controller and control method for three-phase machine
Inventor: POHJALAINEN PASI
IPC: H02P23/30
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To brake vibration caused by a filter effectively, without modifying the conventional method and apparatus significantly by correcting the values of reference flux and reference torque, based on the current flowing through a filter and/or the output voltage thereof. SOLUTION: Output voltage of a filter is measured for each phase and variables, corresponding to the stator flux, are determined by means of a multiplier 5 and a subtractor 7. The voltage is divided into a parallel component and a right-angle component, and then the voltage is multiplied by the stator flux by means of a vector product forming-element 9 and a scalar product- forming element 10. Each component passes through a multiplier 5 and a limiter 6, before being subtracted from a reference flux value. Consequently, conventional DTC method and the essential part of a corresponding apparatus can be used, without requiring significant changes, and vibration caused by the filter can be braked effectively.

Title: Auto-closing door lock device for vehicle
Inventor: PATORITSUKU DAURINGU
IPC: E05B85/24
Filed: 1993-03-11
Abstract: PURPOSE:To completely close a door by applying the constitution where an interlock lever and a latch are engaged with each other in half-latched state, but the engagement thereof is disabled, even when an actuator operates and the interlock lever is thereby caused to rotate. CONSTITUTION:A lock device is so constituted that an interlock lever 20 having a slide member 31 and a latch 7 are engaged with each other, when the latch 7 turns into half-latched state, but the engagement thereof is disabled, even when an actuator 41 operates before the half-latched state and the lever 20 is thereby caused to rotate. In door open state, the interlock lever 20 stops at a standby position, due to the resilient force of a spring 30, while the latch 7 is made to stop at an open position on the resilient force of a spring 13. When a door is closed in that state, the latch 7 turns to a half position. Then, when the actuator 41 is caused to rotate and the lever 20 is shifted to an operation finish position, the lever 20 is engaged with the full-latch engagement step section 18 of the latch 7, thereby completing a door closing process.

Title: Lithium secondary battery using method
Inventor: KOBAYASHI TETSUO
IPC: H01M10/052
Filed: 1999-03-23
Abstract: PROBLEM TO BE SOLVED: To provide a large battery excellent in a cycle life at a low cost and to restrain the heat generation of the battery due to current carrying by using it in a specific region of charge capacity. SOLUTION: A lithium-nickel composite oxide having a layered halite type crystalline structure expressed by a composition formula LiNi1-xMxO2 (M is one or more kinds of elements within Ti, Mn, Co, Al, Mg and Ga; 0<=x<=1) is used for a positive electrode active material of a battery. This dissolves the deterioration in a high-temperature use environment. The battery is used by repeating charge and discharge in a region of 30-100% of its charge capacity. As a result, heat generation due to current carrying during use is restrained, and an excessive output state due to the rapid progress of the battery reaction is avoided. The possibility of the rupture and flaming of the battery due to temperature rise is eliminated as well.  Since the use region of the battery is limited so that its usable period per charge is shortened, the battery is particularly suitable for a hybrid type electric vehicle.
