Title: Process for producing a bumper for a vehicle
Inventor: TAKEUCHI ATSUSHI
IPC: B29C45/26
Filed: 1996-10-31
Granted: 2000-03-07
Abstract: A process for producing a bumper for a vehicle uses a first step of injecting an outer layer forming material into a bumper forming cavity through a gate in a mold, and a second step of injecting a core forming material, thereby allowing the core forming material to flow into the outer layer forming material existing in said gate and said cavity, while allowing the outer layer and core forming materials to flow within the cavity.  In the mold, the volume of a mounting portion forming area of the bumper forming cavity is set so that the thickness t1 of at least a mounting portion of the bumper for mounting to a vehicle body to extend laterally from a central portion of the vehicle body can be larger than the thickness t2 of a bumper main portion excluding the mounting portion, and the gate opens into the mounting portion forming area.  Thus, the outer layer forming material can be allowed to flow substantially uniformly over the entire cavity, thereby enhancing the filling rate of the core forming material.

Title: Three-dimensional drawing system and method
Inventor: KROITOR ROMAN B
IPC: G06T15/00
Filed: 1996-11-22
Granted: 2006-01-31
Abstract: A method for generating images that appear as complex three-dimensional surfaces when viewed using a stereoscopic viewing system, using only a minimum amount of data to define the images. The stereo contours of a complex three-dimensional surface are drawn using a three-dimensional computer drawing system and three-axis input device. The drawing is viewed with a stereoscopic viewing system using, e.g., a CRT where the left and right eye images are time multiplexed in sequential fields and liquid crystal shutter glasses synchronized with the CRT display. Simply by drawing closed loops in space, filling the closed loops with color, and drawing a minimum number of other stereo contours, an image is created which appears to define a complex three-dimensional surface. The image creates a mental perception of a complete solid object by providing to the observer's eye only the minimum cues required by the brain to create stereo objects with complex surfaces, taking advantage of the stage of human neural processing in which the images the eye sees are coded into similar stereo cues. The normal image processing of the brain is in effect substituted for the complex mathematical processing of prior systems to create objects perceived as having three-dimensional volume and surfaces. Therefore, the tedious design and computations required by present systems to produce a full computer graphics description of the object are eliminated, thereby substantially reducing the time required to draw three-dimensional objects as well as the processing requirements where the images are processed by computers, thus making it possible for artists to create three-dimensional images as simply and intuitively as two-dimensional images have historically been created on two-dimensional surfaces.

Abstract: Quadrature Amplitude Modulated signals are generated from data bits by using a first Quadrature Phase Shift Keying (QPSK) modulator for encoding a first pair of the data bits into one of four carrier signal phases, thereby producing a first QPSK signal. A second QPSK modulator encodes a second pair of the data bits into one of four carrier signal phases, thereby producing a second QPSK signal. The first QPSK signal is amplified to a first power level, and the second QPSK signal is amplified to a second power level. The first and second amplified signals are then combined to produce a signal in which four data bits are encoded. In another aspect of the invention, a new type of modulation, called Offset Quadrature Phase Shift Keying (OQPSK), is used in place of the first and second QPSK modulators, so that an Offset Quadrature Amplitude Modulation (OQAM) transmitter is formed.

Abstract: A low cost prefabricated fireplace is provided with an open-ended fireplace box which requires no outer sheet metal shroud or housing as employed in the prior art sheet metal fireplaces. The novel fireplace box has at least five walls which consist substantially of insulating reinforced ceramic fiber (RCF) material and a binder. A modular burner system is removably mounted on the bottom wall of the fireplace box and a floor panel is mounted on the modular burner system forming an air chamber below the floor panel in the fireplace box. A decorative surround trim is attached to the open end of the fireplace box which serves to support fixed or operable glass doors. A log set which may include a log burner is mounted above the floor panel which supports a decorative log set. Apertures are made in the sides or top of the fireplace box to accommodate an air supply and/or an exhaust stack. The fireplace box serves as a base unit to which other fireplace components are attached, connected or supported so that the need for conventional sheet metal is substantially eliminated. The resulting fireplace can be completed in many different configurations using a common fireplace box which needs no additional surrounding insulation for installation in a room.

Abstract: An oxide coating is formed on zirconium or zirconium alloys of refined microstructure by a process comprising at least the step of inducing an appropriate altered surface roughness such that subsequent oxidation results in a uniformly thick oxide coating. An oxide coating of uniform and controlled thickness is especially useful on orthopedic implants of zirconium or zirconium-based alloys to provide low friction, highly wear resistant surfaces on artificial joints, such as hip joints, knee joints, elbows, etc. The uniformly thick oxide coating of controlled depth on oxide coated prostheses provides a barrier against implant corrosion caused by ionization of the metal prosthesis.
