Title: Apparatus and method for creating three-dimensional objects
Inventor: CRUMP STEVEN SCOTT
IPC: B29C67/00
Filed: 1990-10-16
Granted: 1995-09-05
Abstract: Apparatus  incorporating  a  movable  dispensing  head provided with a supply of material which solidifies at a predetermined temperature,  and a base member, which are moved relative to each other along "X," "Y," and "Z" axes in a predetermined pattern to create three-dimensional objects by building up material discharged from the dispensing head onto the base member at a controlled rate.  The apparatus is preferably computer driven in a process utilizing computer aided design (CAD)  and computer-aided manufacturing (CAM) software to generate drive  signals  for controlled movement  of the dispensing head  and base member  as material  is  being dispensed.     Three-dimensional objects may be produced by depositing repeated layers of solidifying material until the shape is formed.    Any  material,  such  as  self-hardening  waxes, thermoplastic  resins,  molten metals,  two-part  epoxies, foaming plastics, and glass, which adheres to the previous layer with an adequate bond upon solidification, may be utilized.  Each layer base is defined by the previous layer, and each layer thickness is defined and closely controlled by the height at which the tip of the dispensing head is positioned above the preceding layer.

Title: Slide switch
Inventor: TAKANO TSUNESUKE
IPC: H01H15/04
Filed: 1990-11-02
Granted: 1995-01-17
Abstract: Slide switches have an electrically insulated slide body which is slidably disposed within an interior cavity defined in an electrically insulated support housing.  The slide body has a knob which projects through an opening defined in an upper wall of the support housing so as to allow manual movement of the slide body between the first and second positions.  At least one pair of elongated conductors is provided with the opposed ends being fixed to an opposed pair of side walls of the housing so that the fixed conductors extend parallel to one another, but are positioned in spaced relationship transversely relative to the reciprocal movement of the slide body within the support housing.  The slide body carries a movable conductor which is sized and configured so as to be in contact with the pair of elongate fixed conductors when the slide body is in its first position so as to make an electrical circuit therebetween.  Movement of the slide body thus disengages the movable conductor from the pair of elongate fixed conductors so as to break electrical contact therebetween.  A retaining plate closes lower end of the interior space of the housing such that the pair of fixed conductors are in space relationship thereto.

Granted: 1999-08-03
Abstract: Errors or failures in a transmission system can be accurately predicted by a system which processes error or failure data collected by the transmission system during uniform intervals to yield data indicative of the errors or failures during each of a plurality of non-uniform, overlapping intervals. The errors or failures measured during the non-uniform intervals are selectively weighted and summed within a neural network, trained with historical error or failure data, to yield a set of predictions, each representing the predicted number of errors or failures during each non-uniform interval. The predictions from the neural network are then thresholded by a control unit and used to raise an alarm which signals the possibility of error or failure in the transmission system.
