Inventor: BARNEA DANIEL I DR
IPC: G02B3/14
Filed: 1988-07-09
Abstract: Optical lens with variable servo-controlled focusing, which is formed by a pair of optical diaphragms (1, 6), which each have a circumferential rim and of which at least one is flexible. In this arrangement, the mount (8") retains the diaphragms (1, 6) at their rims located firmly next to one another such that there is defined between the surfaces of the diaphragms (1, 6) and their mounted circumferential rims an enclosed volumetric space (9) which is filled with a refracting fluid (20). A control device (31) which interacts with the mount (8") permits the optional application of forces to the circumferential rims of the diaphragms (1, 6) which change the fluid pressure in the enclosed volume (9A). The diaphragms (1, 6) and the mount (8") are constructed and arranged such that the diaphragm surfaces can be changed in an essentially spherical fashion in response to pressure changes in the fluid (20).

Abstract: Conveyor equipment, for moving loads (9) from a loading location (13,15) to a discharge location (14,16) situated one above the other, comprises a conveyor belt (1) to which load supports (4) are pivotally attached by hinges (5). In their operating position the load supports extend perpendicularly from the conveyor belt (1) but on reaching the discharge location (14,16) can tilt downwardly to allow the load (9) to move onto receiving means (6,7,10,11,12). If the discharge location (14) is uppermost, tilting of the supports (4) is by engagement between the support (4) and a pivotally mounted platform (7) provided at the upper end of a discharge conveyor (6), and the load (9) is displaced from the support (4) onto the platform (7) by a curved frame (8). If the discharge location (16) is lowermost the movement of the load (9) is intercepted by arms (12) attached to the upper ends of a downwardly inclined slide (11) which leads to a discharge conveyor (10).

Abstract: The present invention relates to a tape for encasing electronic parts. 
     In conventional packages for encasing electronic parts, a film made of polyester resin is used as a cover tape. Peeling of the polyester cover tape from a carrier tape cannot be effected smoothly because the peeling adhesivity between the cover tape and the carrier tape is not uniform. 
     This invention provides a tape for encasing electronic parts comprising a carrier tape having a plurality of recesses for encasing electronic parts and a plurality of guide perforations, and a cover tape pasted onto said carrier tape with an adhesive so as to seal only said recesses while leaving said guide perforations open. The cover tape is a nylon based resin sheet, and the adhesive is an ethylene-vinyl acetate copolymer-based adhesive. The cover tape can be pulled smoothly from the carrier tape during automatic assembly of circuit boards.

Abstract: A single handle-actuated lid opening, closing, and locking mechanism for a large capacity pressure cooker (1) having an open-top cooking vat (3) and a counter-balanced lid (6) shiftable vertically between a vat open and a vat closed position. The mechanism comprises a pair of slotted hook arms (21,22) mounted to either side of the vat. A cam bar (47) extends transversely of the vat lid (6) and is provided with a forwardly extending arms (71,72) near each of its ends. The forward ends of the arms are joined by a bar constituting a handle (73) in parallel spaced relationship to the cam bar (47). The ends of the cam bar support rollers are receivable within the slots (23,24) of the hook arms (21,22). The cam bar (47) is manually shiftable by the handle between a forward lid locking position and a rearward unlocking and lid engaging position. In its forward lid-locking position, the cam bar (47) assumes an over-center orientation with its rollers bearing upwardly against the upper surfaces of the hook arm slots (23,24) and the cam bar body bearing downwardly against the lid. In its rearward unlocked and lid engaging position, the cam bar (47) is rigidly coupled to the lid (6) so that upward and downward forces applied to the handle result in vertical upward and downward movement of the lid between its vat open and its vat   closed positions. A cam bar lock precludes unlocking and opening of the lid when the vat is pressurized.

Abstract: Method and apparatus for managing a plurality of circular buffers are disclosed. The method subdivides a contiguous block of storage into a plurality of interleaved, circular buffers. The storage area is divided into N, M length circular buffers that are interleaved. The interleaving technique starts each of the M buffers at address 1-1, where I is the buffer number (1,2,3,4). 
     Additional subdivisions of an allocated circular buffer of length N are formed by evenly dividing an existing circular buffer into K additional buffers of length L (note that K  *  L = M). For example, 2 additional buffers of length 2 are allocated from the above sixteen byte memory starting with the first K elements of one of the four byte original circular buffers. The increment to get to the next element in each buffer is K  *  M. The address of the Qth element of the buffer is Q * K  *  M + A(i), where A(i) is the starting address of the buffer that is being subdivided.
