Abstract: PURPOSE:To allow the pressure of a resin to a set value of holding pressure within a short time by calculating the moving quantity of an extrusion jig for allowing the pressure of the resin to reach the set value of holding pressure and moving the extrusion jig by the moving quantity. CONSTITUTION:When an injection process is completed to enter a pressure holding process, an operation circuit 62 compares the actually measured resin pressure Xp on the leading end side of a plunger 9 detected through a load converter 18 with the holding pressure set value HP inputted to a holding pressure setting device 63 to calculate the moving quantity DELTAY of the plunger 9 corresponding to the difference pressure DELTAX between both values according to a functional formula Y=f(X) and the other value of the number of pulses corresponding to the moving quantity DELTAY is outputted to a positioning pulse distributor 67. The pulse distributor 67 generates pulses 68 in the number according to the order value 66 and compares the number of the pulses with the number of the pulses 64 emitted from an injection motor controlling encoder 23 to output the difference therebetween digitally as the deviation quantity 70 of pulse frequency and the deviation quantity is converted by a D/A converter to output deviation voltage 73 to a servo amplifier 72. The servo amplifier 72 converts the pulses 64 from the encoder 23 to feedback voltage 75 and amplifies the difference between the voltage 75 and the deviation voltage 73 to drive an injection AC servo motor 19.

IPC: H04N5/073
Filed: 1988-11-14
Abstract: PURPOSE:To make a reading address into more 1H forward phase than ever by generating a prohibiting signal in accordance with the stoppage of an input video signal, thus, prohibiting the writing of a memory and storing the writing address at such a time. CONSTITUTION:A video signal from an input terminal 1 is given through an A/D converter 2 to a memory MEM 3, given to a writing address generator WAG 4 and thus, a video signal is stored with the MEM 3 one by one frame. When the video signal is stopped, a writing prohibiting circuit WIH 5 generates a prohibiting signal in accordance with this and the writing to the MEM 3 is prohibited. On the other hand, a reading address generator RAG 7 generates a reading address in accordance with the reference signal from a terminal 6 and gives it through a switch 8 to the MEM 3. Since the reading address is generated as a 1H delay phase for the writing address, while the output of the RAG 7 is selected, the address signal of the MEM 3 is delayed by 1H more than the writing address.

Abstract: PURPOSE:To provide uniform distribution of reaction of an activated material so as to extend a life of charge/discharge cycle by providing inner bones deflected in either one side of a thickness direction of frame bones and forming an opposite to a side, the inner bone is deflected, into an acute angle part, in a sectional shape of the inner bone. CONSTITUTION:Lead or lead alloy-made peripheral frame bones 2 and inner bones 1 are provided not to position the inner bones 1 in the center of a thickness direction of the frame bones 2 but to provide the inner bones 1 deflected in either one side, and an opposite side to a side, where the inner bone 1 is provided deflected, is formed into an acute angle part 3, in a sectional shape of the inner bone 1. When a plate is formed by charging it with active material paste 4 from a side of providing the inner bone 1 deflected, the inner bones 1 are deformed by receiving a pressure of charging the paste and pressed down to a central part in the thickness direction of the frame bone 2. Since the acute angle part 3 is formed in the opposite side of the inner bone 1, the charged paste 4 is placed around to a reverse side to prevent the inner bones 1 from being exposed in a plate surface and a clearance from being generated between the inner bone 1 and the active paste 4. In this way, the inner bones 1 are prevented from being deflectively provided in the active layer 4 to increase a life of charge/discharge cycle by providing uniform distribution of reaction of active material.
