Inventor: NISHIMURA SHINGO
IPC: G10L17/18
Filed: 1989-11-16
Abstract: A speaker recognition system for recognizing a speaker on the basis of input speech by the use of a neural network provided with a plurality of layers.  The variation with time of an inherent characteristic of speech is used as an input to the neural network.  Specifically, the variation with time of an average inherent characteristic of speech within a fixed time is used as the input to the neutral network.  The inherent characteristics of speech used include a frequency characteristic of speech, a pitch frequency, a frequency characteristic of the speech waveform subjected to high-frequency emphasis; a linear prediction coefficient, and a PARCOR coefficient.

IPC: G01G19/414
Filed: 1990-03-12
Abstract: An electronic postal scale measures the weight of an item in metric or in avoirdupois units, at the user's election. The scale also calculates a postal or shipping rate for the item, in accordance with a stored rate table defined in either metric or avoirdupois units. When the user selects a class of service, the scale determines whether there is a stored rate table for that class in the currently elected weight units. If not, the scale automatically changes to the other weight units and calculates a rate according to a stored table in those other units.

Inventor: PETERSEN RALPH
IPC: B25B7/02
Filed: 1990-09-11
Abstract: A quick release for a conventional plier-type, toggle-locking hand tool comprises a compound toggle link.   The new link is pivotably mounted between the movable handle and the conventional toggle member.  Four pivot points rather than the usual three form the "power line" of the tool.  Locking the tool involves pushing the two internal pivot points inwardly across the power line.        Release involves opening the handles which moves the internal pivot points back across the power line.  Depending on the dimensions of the  actual hand tool,  the mechanical  advantage of the novel compound link is between 4 to 16.

Abstract: METHOD AND APPARATUS FOR REMOVING LIQUID FROM THICKENERS        FILTERS, WASHERS AND CORRESPONDING DEVICES         ABSTRACT OF THE DISCLOSURE The present invention relates to a method and an apparatus for removal of liquidfrom thickeners, filters, washers and the like dewatering devices. The known water separating devices comprise a drop leg and a large filtrate tank in which gas is removed from the gas-containing filtrate supplied via the drop leg, to reduce the problems caused by the gas in pumping the filtrate. The method of the invention obviates the need of both the drop leg and the filtrate tank. The filtrate is guided from the dewatering apparatus via an enclosed flow passage to a filtrate pump and the pressure difference required by filtering is at the same time generated at least partially by the said pump. The above described method is carried out by a filtrate removing apparatus whichcomprises a filtrate duct (22, 42, 62) which forms an enclosed flow passage, and a filtrate pump (23, 43, 63) connected thereto.

Filed: 1991-03-07
Abstract: APPARATUS FOR MOVING APART SUCCESSIVE WEBS OF A SERIES      OF WEBS HAVING SECTIONS IN ZIG-ZAG FORMATION               ABSTRACT OF THE DISCLOSURE           A continuous web of paper is subdivided into a series of discrete webs of finite length, and successive discrete webs of the series are provided with looped sections in zig-zag formation. successive discrete webs of the series are moved forwardly and away from the next-following webs of the series while advancing toward a stacking station to thus establish between successive discrete webs gaps of predetermined width.  The making of gaps involves advancing the discrete webs with the upper reaches of three parallel foraminous endless belt conveyors which attract the webs and move them toward the stacking station.  The median belt conveyor is accelerated when it is approached by the trailing end at a speed exceeding the speed of the other conveyors and of the leader of the next-following discrete web.  The median belt conveyor is thereupon disengaged from the accelerated discrete web and is decelerated so that it reassumes a predetermined starting position relative to the other belt conveyors.

Filed: 1991-03-28
Abstract: An optical  disk  recorder,  or  other  apparatus,  use  a rotary actuator for supporting a work tool,  such as an objective lens which is pivotable or rotatable about a pivot pin.   Rotation causing or tracking coils on the rotary  actuator  are  disposed  adjacent  to  permanent magnets  to  selectively effect  rotation of  the  rotary actuator about the pivot pin. A bias electrical current is supplied to these coils to  generate magnetic fields which  are  in opposite  rotational  senses;  such  fields force  the  rotary actuator against the pin in such a manner  that  the point  of  contact between  the  rotary actuator and the pin follows the rotation of the actuator about the pin.

IPC: H01L25/00
Filed: 1991-03-28
Abstract: The present invention is a molded Hybrid Integrated Circuit package in which a carrier substrate with a various circuit elements including an integrated circuit is supported within a resilient craddle formed by down-set and compliant portions of leads arranged in a quad configuration around the periphery of the carrier substrate, with ends of the down-set portions being secured to pads arranged on the periphery of the carrier substrate. Prior to the assembly with carrier substrate and molding of the resultant subassembly, the leads form a part of a lead frame including elongated bar and dam-bar on each of the quad sides interconnecting end and central portions, respectively, of the leads, and an interconnecting array of connecting links andbridges at the ends of the dam-bars. The lead-frame design, including the down-set and resilient portions of the leads, provides for the stress relief between the carrier substrate and the lead frame, especially during the thermo-bond lead attachment and molding of an encapsulating resin around the carrier substrate and leads subassembly.

Title: Multi-part dowel
Inventor: OLDENDORF GUNTER
IPC: E04F13/08
Filed: 1990-03-16
Abstract: Abstract The invention concerns a multi-part dowel with an outer body (2), which has an approximately cylindrical shank (4) and an inner body (12).  In the position of use, the outer body (2) and inner body (12) engage with each other in the same way as a multiple screw-thread.  The outer body (2) has, in its solid shaft (4), helical grooves (8) which are positioned to form a star when viewed in cross-section and which form an internal screw-thread.  The inner body (12) has matching helical ribs (14) also positioned to form a star. The pitch of the thread is greater than the length of the thread.  In what is the front section of the outer body (2) when the dowel is used, the grooves themselves, or slots (10) aligned with them, extend to the outer wall of the outer body (2). The dowel can be used for fixing building materials, such as woven textile or fibre-glass materials, to outside walls, interior walls or ceilings.  The dowel makes it possible to align the material in a single plane.  To this end, the inner body (12) can be displaced relative to the outer body (2).  When it is penetrated by the inner body (12), the front section of the outer body (2) is expanded in the same way as a straddling dowel.  Ventilation channels (30) run the whole length of the dowel.
