  • Patent number: 4535583
    Abstract: A rotary type capping apparatus for screwing caps onto the mouths of containers includes a turn table provided with a plurality of container holders fixedly mounted along the periphery thereof, a main motor for rotating the turn table in a predetermined direction and a capping head assembly including a plurality of cap holders, each of which is disposed above the corresponding one of the plurality of container holders, so as to be movable closer to or away from the turn table. In one aspect of the present invention, the capping apparatus includes at least one motor exclusively used for rotating the cap holders for causing the caps held by the cap holders to be screwed onto the mouths of containers. In another aspect of the present invention, the capping apparatus is so structured to increase the torque applied to a cap until it has reached a predetermined level during the cap screwing operation thereby insuring that all caps may be screwed on as tightly as desired.

  • Patent number: 4533043
    Abstract: An integrated circuit package magazine and receptacle is provided in which one or both ends of a longitudinally elongated magazine tube (10) are cut-out to form inwardly facing spring gates (16) which have ends (18) abutting ends (22) of a series of integrated semiconductor packages (20) slidably contained on a rail surface (13) in the interior of the magazine. In its neutral inward position spring gate 16 functions to prevent egress of the semiconductor packages while allowing easy ingress of the packages by spring movement of the spring gate upwardly into a position in the same plane as the top wall (15) of the tube. The tube may take various exterior and interior configurations. Automatic release of semiconductor packages from the tube is provided by utilizing the tube in conjunction with a receptacle (30) having a longitudinal rail (34) onto which the magazine is insertable.

    Abstract: Alignment apparatus particularly for a semiconductor wafer (140) includes a horizontal support plate (134), a horizontal rotatable theta plate (106) below the support plate and a horizontal x-y motion plate below the rotatable plate. Three piezoelectric linear drive motors (128-130) are mounted depending from the rotatable plate and having linear shafts (128a, etc.) extending thereabove to support the support plate, drive the support in the z-axis and then differentially operated to tilt the support plate. A pair of linear piezoelectric motors (110,115) drive the motion plate in x- and y-directions. A theta drive linear piezoelectric motor (137) functions to rotate the theta plate (106). Flexure connections (113, 117, 119, 121, 138, 144) are provided between the various motors and plates. Mask registration means (124, 125) extends upwardly past the edges of the plates to initially gap the wafer-to-mask distance.

  • Patent number: 4491888
    Abstract: A fixed disc drive type of rotating disc memory storage device includes an annular elastomeric pad that is engaged between the actuator base plate and a bowl-shaped casing. The base plate has a circular platform portion with the boss for the spindle shaft for the discs being formed at its center. The annular pad forms an air-tight seal at the edge of a circular opening in the lower casing to prevent dust from entering the housing. The annular pad is engaged against the entire side marginal area of the base plate so that it dampens resonant vibrations in the base plate thus providing stable servo response within the range of said resonant vibration range.

  • Patent number: 4484026
    Abstract: A touch tablet for use in entering data into a computer or graphics display device comprises a first four-sided sheet containing a resistive material on one surface thereof, a second four-sided sheet containing a resistive material on one surface thereof and a spacer for holding the first sheet apart from the second sheet. The first sheet is oriented relative to the second sheet such that the resistive material on one of the two sheets faces the resistive material on the other sheet. Each sheet contains conductive strips formed on two of the four sides of the sheet in contact with the resistive material. A potential is applied across the conductive strips on one of the two sheets. The input lead to an output amplifier is connected to the two conductive strips formed on the other of the two sheets. A user presses the first sheet into conduct with the second sheet and the output voltage from the output amplifier is representative of one of the two coordinates of the point of contact between the two sheets.

  • Patent number: 4465908
    Abstract: A hand controller for use in controlling the motion of a cursor on a video display comprises a spherical surface on which is mounted a flat plate. On the bottom of the flat plate is a unique electrical switch capable of indicating the direction in which the flat plate is rocked over the spherical surface. Attached to the bottom of the flat plate adjacent the spherical surface is a spring consisting of a substantially flat center portion and four spiralling arms extending from the periphery of said center portion to attach to the structure on which the spherical surface is mounted. When the flat plate is rocked over said spherical surface, the spring generates a restoring force which, upon removal of the rocking force, restores the flat plate to its nominal position. The spring makes possible rocking motion of the flat plate over the spherical surface without pinning the flat plate to a point on the spherical surface.

  • Patent number: 4463679
    Abstract: The present invention relates to pyrotechnic flares. A hollow support structure (1) receives a first pyrotechnic composition (2) with a delay action internally and axially, whereas it receives a second pyrotechnic composition (4) which is slower than the first, in holes (101 to 151), arranged radially and of decreasing length. An initiator (3) initiates the composition (2) on the side where the radial through-holes are longest. Located outside is an illuminating composition (5), which may thus be illuminated virtually at the same time over the entire length of the product.Application in particular as an optical or infra-red counter-measure.
