Title: Method for exchanging screen block for continuous screen changer and screen block
Inventor: ITO YASUSHI
IPC: B29C47/68
Filed: 1990-10-23
Abstract: PURPOSE:To obtain continuously a molded item with good quality without mixing a resin with changed quality by pushing a waiting screen block to a position where the apex part of a resin filtering path thereof is positioned in an extrusion path for a molten resin and exchanging the screen block after the molten resin in the extrusion path is filled in the screen block from the apex part of the filtering path. CONSTITUTION:A resin filtering path 43 with a screen 42 is elliptically formed and when a waiting screen block 40C is pushed in such a way that an apex part 44 of the resin filtering path 43 is positioned in an extrusion path 2 for a molten resin, a part of the molten resin in the extrusion path 2 flows into a screen block 40C from the apex part 44 and the screen block is filled with the fresh molten resin without changing in quality. By pushing it furthermore, a filtering screen block 40D is pushed out and the screen block 40C is pushed to a position where it coincides with a molten resin extrusion path 2. While the molten resin is continuously filtered by means of screen films 40D and 40C, exchange of a screen block 40 is performed without mixing a resin with changed quality.

Title: Mixer circuit
Inventor: TANAKA SATOSHI
IPC: H03D7/12
Filed: 1995-11-01
Abstract: PROBLEM TO BE SOLVED: To suppress the local leak by using about half number of elements by turning on and off the bypass capacitance connected to the source of an AC amplifier via a 2nd FET which has a switching operation. SOLUTION: A mixer circuit turns on and off the bypass capacitance connected to the source of an AC amplifier consisting of a depletion type FET operating at a low current level by means of a 2nd FET having a switching operation. Then the mixer circuit eliminates the local leak occurring via the parasitic capacitance Cp by the local signal supplied from the gate of the amplifier via the capacitance Ccom. The local leak is not converted into a current signal as long as the gate potential is moved in an in-phase by an extent equal to the movement of a source electrode caused by a local leak signal. Thus the local leak is never outputted. In such a constitution, a mixer that is suitably applied to the mobile communication for suppression of the local leak is obtained by using a small number of elements.

Filed: 1986-12-01
Abstract: PURPOSE:To avoid the operation of a motor from being interrupted upon switching an operation mode, by nullifying a current commanding signal for a given period of time from the time of the switching of the operation mode. CONSTITUTION:An operation mode discriminating circuit 12 outputs an operation mode switching signal when the operation mode of an induction motor 1 is switched. The magnitude A of a current command, being outputted from a vector operating unit 5, is inputted into a current comparator 13 and when the value is larger than a predetermined value, set by a current setter 14, a logical operating signal is outputted. Accordingly, when the operation mode is switched under a condition that the magnitude A of the current command is larger than a predetermined value, the changeover switch 16 is switched to the opposite position for a given period of time, therefore, the magnitude B of the current command, inputted into a multiplier 17 during this period, is zero and, accordingly, a current commanding signal D, outputted from the multiplier 17, becomes zero for a given period of time.
