Patent CA-2100109-A1 (CA)
Title: Stereoscopic Display Apparatus and Method
Inventor: ARITAKE HIROKAZU
IPC: H04N15/00
Filed: 1993-07-08
Abstract: A plurality of 2-dimensional images having parallaxes in only the horizontal directions when an object to be displayed  is seen from different positions in the horizontal direction are inputted.  The 2-dimensional image  is divided in the vertical direction into 1-dimensional line images which are long in the horizontal direction.  A phase distribution of  a corresponding hologram  segment  is  calculated from the pixels of the line image.  The calculated phase distribution  is expressed on a hologram forming surface  of a phase expressing section using a display.  A reproduction light is irradiated and converted into an optical wave front and is further enlarged in the vertical direction, thereby displaying a solid image.  The 2-dimensional images are inputted by photographing the object by a plurality of cameras  arranged  in the horizontal direction.  The 2-dimensional images can be also produced by interpolating  calculations  from two 2-dimensional images which were actually photographed.  The 2-dimensional images which are used in the phase calculations are subjected to a process such as enlargement, reduction, or movement of the coordinate position, thereby adjusting the size and position of a solid image.  The phase distribution  is  calculated every RGB components from the 2-dimensional images and the reproduction light is irradiated every color, thereby displaying a color solid image.

IPC: D04C1/06
Filed: 1993-11-05
Abstract: A system for reducing packing ring spin and opening up of the joints formed by the ends of a packing ring during break-in of trapezoidally-shaped mechanical braided packing involves utilization of additional warp yarns within the sides of the packing. These additional warp yarns bulge the packing at the sides of the packing above its horizontal centerline such that the outer portion of the packing is provided with a solid rectangular cross section. The solid section increases frictional contact between the rings and the stuffing box and between the rings themselves to eliminate packing ring spin.      When the packing is wrapped around a shaft the bulging sides become flat for secure elongated anti-spin contact both between the packing rings and between the end ring and the bottom of the stuffing box. The utilization of the anti-spin configuration eliminates packing ring spin and the opening up of the joints formed by the ends of the packing rings during break-in, regardless of operator error in the installation of the packing rings.

Title: Columnar-grained polycrystalline solar cell and process of manufacture
Inventor: HALL ROBERT B
IPC: H01L31/18
Filed: 1993-10-07
Abstract: The invention relates to techniques for manufacturing columnar-grained polycrystalline sheets which have particular utility as substrates or wafers for solar cells. The sheet is made by applying granular silicon to a setter material which supports the granular material. The setter material and granular silicon are subjected to a thermal profile all of which promote columnar growth by melting the silicon from the top downwardly. The thermal profile sequentially creates a melt region at the top of the granular silicon and then a growth region where both liquid and a growing polycrystalline sheet layer coexist. An annealing region is created whets the temperature of the grown polycrystalline silicon sheet layer is controllably reduced to effect stress relief.

Abstract: There is provided a truck wheel-spacing changing method in which the basic structures of the bogie frame and the truck are not made complicated, and only an improvement of the bearing portion is required; the running stability is not inferior to that of a conventional truck of a fixed wheel-spacing type; and the track includes no moving part and the maintenance of the wheel gauge changing system is easy.            The truck is equipped with axle boxes slidably supporting axles extending between side beams of the bogie frame. Axle box receivers are selectively and releasable connected with the axle boxes at a plurality of predetermined positions by locking members. When the truck is moved from the one railway to a junction rail-way, the auxiliary wheels mounted on axle box receivers of the truck engage with running paths and raise the vehicle (truck and vehicle body) except the wheel sets and releasing said locked condition by the locking members. When moved through a region where the track gauge of the junction railway is changing or where spacings of inside or outside guide rails is changing, the wheels are pushed by a pair of guide rails or a pair of junction railway rails and shifted transversely together with the axle boxes relative to the axle.          Finally, when the truck is moved completely over the junction railway section, a truck wheel-gpacing changing operation is completed.

Title: Cystoscopy Splash Shield
Inventor: POTTS WILLIAM E
IPC: A61B19/08
Filed: 1992-09-11
Abstract: A cystoscopy splash shield for use during surgery in which a large volume of human liquid is involved.  The splash shield  includes a rectangular shaped transparent plastic sheet with a strip of adhesive along its short edge and a hole present in the approximate middle of the sheet.   The short edge of the plastic sheet is affixed to the torso of the patient by the adhesive strip.  The remaining portion of the shield is draped over the groin area of the patient with overlap over and between the patient's legs.  The shield is positioned so its hole is over the groin area to undergo surgery.  A medical optical instrument may be inserted into the hole which is sealed around its circumference.   As a result, a physician conducting surgery in the groin area is protected from any splashing fluids from the patient.

Title: Power saw fence guide
Inventor: GARUGLIERI ANDREA
IPC: B27B5/20
Filed: 1994-08-10
Abstract: ABSTRACT OF THE DISCLOSURE   A POWER SAW FENCE GUIDE      A combination mitre and bevel saw 10 is disclosed which includes an elongate fence guide 74 operatively connected to the saw blade assembly 20 and pivotable between a retracted position and an extended position in the plane of the saw blade 26.  A spring 72 biasses the-fence guide 74 into its retracted position.  The fence guide 74 may be pulled down by the saw operator into its extended position so as to indicate the position at which the saw blade 36 will impinge upon the workpiece and so as to allow the setting of two fence members 17a, 17b accordingly.  The fence guide 74 includes a leading 78, which indicates the width of cut which the saw blade will make in the workpiece and a wider portion 80, trailing the leading edge 78, which indicates the optimum spacing of the fence members 17a, 17b.  As the saw blade 36 is pivoted about a bevel axis 92 to enable bevel cuts to be made, the fence guide 74, supported on a guide support 62 also pivots about the bevel axis 92 by a corresponding amount.  Thus, the fence guide 74 always lies in, and pivots in, the plane of the saw blade 36.      It goes without saying, of course, that the fence guide 74 lies in the plane of the blade 36 and, at least in the position A, the blade, on pivotting about axis 28, must not impinge the guide 74.  The same is also true of the housing 20 which, in the plane of the blade 36, has an opening permitting entry of the fence guide 74 within the housing 20 when the latter is pivotted downwardly about axis 28.      The fence guide 74 permits an accurate estimate of the cut which will be made in a workpiece and also provides for accurate and optimum positioning of the fence members 17a, 17b.     (Figure 5).

Abstract: A method of and apparatus for precisely shaping heated glass sheets as the sheets advance along a bed of conveyor rolls. The conveyor rolls comprise a core member having axially aligned opposite sections and an arcuately curved central portion, with a flexible sleeve surrounding the core member. The sleeves are rotated in unison about the core members to convey the sheets. The core members are pivotable in unison between a first position where the curved control portions lie in a common plane for conveying the flat sheets and a second, lowered position whereat the curved portions define the shape to which the sheets are to be deformed. Vertically reciprocable top surface press units are mounted above the path of the glass sheets. The press units include curved stationary mandrels having freely rotatable flexible sleeves thereon.      The configurations of the mandrels are such that in operative position the mid portion of the mandrel of the first press unit is slightly close to the path defined by the conveyor rolls than the edge portions, and the edge portions of the second mandrel are slightly closer to the path than the mid portion.
