Title: Driving system for variable reluctance motor
Inventor: SAKANO TETSURO
IPC: H02P25/08
Filed: 1990-04-06
Abstract: PURPOSE:To facilitate the control of driving of a motor by controlling so that an average voltage between exciting coils is changed linearly with respect to the deviation of current. CONSTITUTION:The driving circuit of exciting coils L for one phase of a motor is constituted of switching elements (Tr) Q1, Q2 and diodes D1, D2. The deviation epsilon of current controls said driving circuit through an absolute value circuit 10, a PWM circuit 11, a polarity judging circuit 12 and the like. In a closed loop current control, the PWM circuit 11 compares the the absolute value ¦epsilon¦of the deviation epsilon of current with a carrier signal and produces a PWM signal, whose duty ratio is proportional to the ¦epsilon¦. When epsilon>0, the Tr Q1 is closed and the Tr Q2 is opened and/or closed by the PWM signal. When epsilon<0, the Tr Q1 is opened and/or closed by a signal obtained by converting the PWM signal while the Tr Q2 is opened. Thus, an average voltage between exciting coils L becomes linear with respect to the deviation epsilon of the current.

Abstract: PROBLEM TO BE SOLVED: To improve the appearance of a finished product without breakage and creases by pressing a binder fiber of a specifically blended composition in a molten state. SOLUTION: An unwoven fabric comprising 70-90% of polyester colored cotton and 10-30% of binder fiber and an intermediate layer made up of 45-65% of mixed cotton and 35-55% of binder fiber are integrally joined together by fiber entanglement and the welding of the binder fiber, and a base material layer made up of 30-50% of pulp and 50-70% of the binder fiber is sequentially welded to the back face of the integrally welded layer. The binder fiber is defined as a fiber whose melt point is lower 40 deg.C or more than the melt point of polyester fiber. When the content of the binder fiber of the surface layer is 10% or less, the frictional strength falls short and when the content is 30% or more, the appearance of a finished product is made less presentable due to the molten mass of the binder fiber.  The content ratio of the binder fiber in the intermediate layer should preferably be within the range of 35-55% so that satisfactorily flawless molding, excellent soft feeling and dependable shape retaining properties are ensured. The base material layer shows superb molding properties and shape retaining properties under heating, when the content of the binder fiber is 50-70%.
