Patent CA-2107975-C (CA)
Inventor: HALL ROBERT B
IPC: H01L31/04
Filed: 1993-10-07
Granted: 2003-08-05
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.

The width dimension extends from the opening to a lateral outside edge of the side wall at the forward limit, and gradually diminishes inwardly toward the rearward end of the opening. The height dimension is a maximum at the forward limit and gradually diminishes toward the rearward end of the opening.

Abstract: ABSTRACT OF THE DISCLOSURE         A spreader for glue-coated particles for the production of particleboard in a steel belt continuous press has a clump breaker with at least two disintegrating rollers which are provided with circumferential rows of equispaced teeth which rows are equispaced axially along each roller. The rows of teeth of the two rollers interdigitate to form a gap of meandering shape. The disintegrating capacity of the clump breaker depends on the gap width. The clump breaker substantially prevents local regions of higher density or more compact character in the particleboard and, thus, also reduced damage to the press caused by those regions of higher density.

Title: Antitumor vaccines
Inventor: SPITLER LYNN E
IPC: A61K47/48
Filed: 1992-11-25
Granted: 2002-07-02
Abstract: Tumor-associated antigens which caracterize tumors of given histologic types are exemplified by CO-029, which is asso-ciated with tumors of the gastrointestinal tract, colorectum and pancreas, and by GA-733-2, which is associated with tumors of the gastrointestinal tract, prostate, cervix, ovary, bladder, lung, breast, colorectum and pancreas. These antigens, which are broad-ly shared by these tumors, can be synthetically prepared, independent of the tumor itself. These independently prepared antigens are useful as active ingredients in compositions which provide therapeutic protocols to subjects that harbor such tumors or are at risk from such tumors. The vaccine compositions of the invention have enhanced antigenicity by virtue of encapsulation of these antigens in liposomes or covalent coupling of the antigens with liposomes.

Abstract: Upon the reception of a page message from a base station (step S1-1), a wireless portable telephone transmits to the exterior a page response which is a response to the page message (step S1-2). If, when transmitting the page response, a data transmission error has been detected (step S1-3), then a predetermined warning tone is generated (step S1-4). Thus, by virtue of this warning tone, the user of the wireless portable telephone can draw out an antenna or move to a place in which the electric field is in a good condition.

Abstract: A method, apparatus, and system for transmitting and receiving an electromagnetic data signal in a moving, linear chain for use primarily in collision avoidance.  Each unit in a chain of units has a processing unit interconnecting a directional receiving element (10e), directional low power transmitting element (12E), a deceleration detector for the unit, and a deceleration detector for a preceding unit in the chain.          In a simple form, motor vehicles (D-H) are the units.  If the invention detects deceleration of a preceding vehicle deceleration of itself, or an identifiable signal from a preceding vehicle such as a blue light, it causes a rearward facing blue light to illuminate.  This blue light indicates to following motorists that the perceived vehicle is decelerating or that a vehicle somewhere in front of it is decelerating.  The blue light also may be received by another vehicle equipped with the invention and consequently be transmitted rearwardly.  In a general form, a data encoded high frequency signal is transmitted rearwardly from a vehicle.  This signal contains information relating to deceleration of any preceding vehicles (Chain Brake) and of the transmitting vehicle (Brake).
