Title: Gate driving circuit and gate driving method of voltage-driven switching element
Inventor: KIN HIRONOBU
IPC: H02M1/08
Filed: 1993-12-22
Abstract: PURPOSE:To equalize current in voltage-driven switching elements which are connected in parallel by driving the voltage-driven switching elements connected to gate terminals of those switching elements simultaneously through a voltage source. CONSTITUTION:Voltage-driven switching elements, IGBT6A and 6B, are connected in parallel. When the IGBT6A is on, the voltage between a gate and an emitter VGEA is VGA+VEA. When the IGBTs are turned on, current flows between the emitters of the two IGBTs which are connected in parallel and then a voltage drop VL1 is generated by a reactor component 5A which appears in a connecting conductor and the emitter potential VEB of the IGBT6B is VEA+VL1. Since voltage VR1(=LL1) is generated across a reactor 7A correspondingly to the voltage drop due to the reactor component appearing in the connecting conductor between the emitters and thereby the gate potential VGB of the IGBT6B increases to VGA+VR1, the voltage between a gate and an emitter VGEA of the IGBT6A and that VGEB of the IGBT6B can be equal.

Title: Dust collecting filter for air purifier
Inventor: YAMAGUCHI TORU
IPC: B01D39/14
Filed: 1991-12-10
Abstract: PURPOSE:To provide a filter enhanced in dust collecting efficiency, capable of being washed and reutilized and reduced in life cycle cost by forming a filter member by combining two kinds of fibrous dielectric materials respectively having positively and negatively chargeable characteristics. CONSTITUTION:A filter member 1 is constituted by combining a fibrous dielectric material (e.g. nylon 6, nylon 66) 2 having a positively chargeable characteristic and a fibrous dielectric material (e.g. Teflon, polyethylene) 3 having a negatively chargeable characteristic in a laminar state. Therefore, even when the filter member is washed using water and a detergent at the time of reutilization, the capacity of the filter member is restored if friction effect due to the passage of air is imparted after drying and the lowering of charge retentivity is not generated and dust collecting capacity is held over a long period of time. Since the fibrous dielectric materials 2, 3 having positively and negatively chargeable characteristics are rubbed with each other accompanied by an increast in the velocity of air passing through the filter member 1, charging effect is enhanced and dust collecting efficiency is enhanced still more.
