Patent GB-2072948-A (GB)
Title: A method of manufacturing an electrode plate electret
IPC: H01G7/02
Filed: 1980-04-02
Abstract: To produce an electrode plate electret, a high molecular film 73 for polarization is disposed on an electrode plate 71 with an intermediate high molecular film 72 being sandwiched therebetween to form a laminated member 74. The intermediate high molecular film 72 has a lower melting point than the high molecular film 73 for polarization. The laminated member 74 is then heated at a temperature in the vicinity of the melting point of the intermediate high molecular film 72 to fusion-weld the high molecular film 73 for polarization to the electrode plate 71 through the intermediate high molecular film 72, and then the high molecular film 73 for polarization is polarized. Alternatively, the film 73 may be polarized before fusion- welding to the plate 71 by way of the film 72. <IMAGE>

Title: Gyrodynamic devices for ocean wave energy conversion
IPC: F03B13/20
Filed: 1980-09-30
Abstract: A rotating flywheel is mounted on a raft which is pivotally attached to a lower raft which is heavier and less buoyant. The rafts are also connected by a reciprocating piston pump. As the floats tilt due to wave action, the upper raft rotates relative to the lower raft due to precession of the flywheel, thus actuating the pump. In another embodiment the rafts are co-planar and hinged together along one edge and each carries one of a pair of contra-rotating flywheels. In a further embodiment the flywheel is formed by a tube bent to form a closed circular path which is filled with a low viscosity fluid which is driven around the closed path at a high speed. <IMAGE>

Title: Process for knitting articles on a circular knitting machine
Inventor: GRIMM HELMUT
IPC: D04B9/14
Filed: 1982-09-15
Abstract: At least one backing thread 86 is inserted 71, if appropriate according to a pattern, into a basic knit by driving out selected needles 92, 97 on at least one knitting system, feeding the backing thread to these and then, by means of sinkers 96 advanced from an outer position to an inner position, shaping the backing thread into loops towards the machine centre and round the front side of the selected needles, in such a way that, during the subsequent delayed driving-out of unselected needles 95, the parts of the backing thread which are grasped by the sinkers come to rest behind these needles. The needles 92 and 97 have long feet and the needles 95 have short feet and the timing of the rise of the needles is achieved by a cam track co-operating with these feet. Standard sinkers 94 hold down the fabric in the conventional manner while the needles 92 and 97 are driven out. Hook sinkers 96 are advanced only during the driving out of the needles 92 and 97 and form the loops in the backing thread 86 in front of which the needles 95 then rise. <IMAGE>

Title: A semiconductor memory
Inventor: YAMAGUCHI YASUNORI
IPC: G11C11/409
Filed: 1983-06-30
Abstract: A memory, such as a dynamic random access memory, has a control circuit (CSG) for controlling the operation start timing of the sense amplifiers so as to make the sense amplifiers start operating at mutually different timings. According to this construction the plurality of sense amplifiers do not start operating simultaneously and consequently, the potential change of a semiconductor substrate can be minimized and the erroneous operation of the dynamic random access memory can be reduced. The sense amplifiers start operating sequentially in the order starting from those which are positioned close to the address decoder circuit to those which are spaced apart from the address decoder circuit. Hence, the operation timing of the address decoder circuit can be set easily. Application of the invention to ROMs and other types of RAM is envisaged. <IMAGE>
