Title: Method of suppressing torsional vibration in motor speed control system
Inventor: WATANABE KANJI
IPC: H02P29/00
Filed: 1991-04-22
Abstract: PURPOSE:To suppress torsional vibration by controlling it in the direction of negating the torque ripple by the torsional vibration of a motor, which is the disturbance of the accelerating torque of a motor, by the torque command compensating signal outputted from an accelerating torque controller. CONSTITUTION:When average speed NMN is input into an acceleration computing element 21, an acceleration NMMD is output, and when the difference between the acceleration command NREFD and the acceleration NMMD is input into an acceleration torque controller 22, a signal DPI is output. When the signal DPI is input into a phase advance compensator, it outputs a signal TDP. Furthermore, torque control of the motor is performed with the signal, where this signal TDP is added as an accelerating torque compensating signal to a torque command signal TRFA, as a torque command. Hereby, it works in the direction of negating the disturbance torque of the motor occurring by the torsion of a load driving shaft during acceleration or load ripple, and can suppressed torsional vibration.

Title: Chopper circuit
Inventor: MINO TOMOAKI
IPC: H02M3/135
Filed: 1985-04-30
Abstract: PURPOSE:To reduce the sizes of a stack, a chopper circuit and to decrease the weight by inserting a reverse blocking diode to the negative side of a DC power source. CONSTITUTION:A reverse flow blocking diode 2 is connected with the negative side of a DC power source 1 to form a circulating diode 6 and a diode stack 10. since a monorail is, for example, separated for both positive and negative poles different from a vehicle, it is not always necessary to insert the diode 2 to the positive side like a general vehicle. Thus, the diode 2 can be inserted to the negative side of a chopper circuit to readily associate the diode 2 and the diode 6 in one stack 10 to reduce the size.

Title: Dust particle detecting method and dust particle detector using this method
Inventor: MIYASHITA HARUZO
IPC: C23C14/00
Filed: 1998-03-19
Abstract: PROBLEM TO BE SOLVED: To efficiently detect dust particles even when a dust particle detector is set in a place remote from a dust particle generating source within a vacuum device by providing a low temperature part in vacuum atmosphere to form a thermal gradient, and moving the dust particle toward the low temperature part by thermal migration action of dust particle. SOLUTION: A low temperature source 102 is inserted to a hole 101 provided in the bottom of a small-sized vacuum chamber 1 from the outside, and airtightly mounted therein. The low temperature source 102 is made of a highly heat conductive material, and a passage 103 formed therein communicates with an inflow port 104 and an outflow port 105. When a dust particle detector is operated, a low-temperature fluid is carried into the passage 103 from the outside to lower the temperature of the surface B of the low temperature source 102. According to such a structure, the temperature of the low temperature source 102 is lower than the ambient temperature, and a dust particle 19 receives a thermal migration action.  This phenomenon is considered to occur by impacting the side surface of the dust particle exposed to a high temperature by a medium molecule having the energy higher than the side surface of the dust particle exposed to a low temperature, and consequently moving the dust particle 19 to the low temperature area.
