Patent CA-2140264-A1 (CA)
Title: Particle binding to fibers
Inventor: HANSEN MICHAEL R
IPC: D04H1/64
Filed: 1993-08-16
Abstract: A binder is applied to particles (602) which are then combined with fibers (600) to bind the particles to the fibers (600). The particles (602) have functional sites for forming a hydrogen bond or a coordinate covalent bond. The fibers (600) have hydrogen bonding functional sites. The binder comprises binder molecules, the binder molecules having at least one functional group that is capable of forming a hydrogen bond with the fibers. A substantial portion of the particles (602) that are adhered to the fibers (600) may be adhered in particulate form by hydrogen bonds or coordinate covalent bonds to the binder, and the binder in turn may be adhered to the fibers (600) by hydrogen bonds. Fibers (600) containing particles (602) bound by this method are easily densified.

Title: Vehicle rotational-angle calculating apparatus
Inventor: IWATA EIJI
IPC: G01C19/00
Filed: 1995-06-29
Abstract: A first sensor outputs a signal representing an angular rate of a vehicle body.  A second sensor outputs a signal representing a direction of the vehicle body.  The output signal of the first sensor is integrated to generate a signal representing a tentative rotational angle of the vehicle body.  First data pieces are generated which represent temporally spaced samples of the output signal of the second sensor respectively.  Second data pieces are generated which represent temporally spaced samples of the tentative rotational angle signal respectively.  Two first data pieces are selected from among the first data pieces.  Calculation is given of a time interval between the occurrence moments of the selected two first data pieces.  Two second data pieces are selected from among the second data pieces. Calculation is given of a direction difference between directions represented by the selected two first data pieces. Calculation is given of a rotational-angle difference between tentative rotational angles represented by the selected two second data pieces. An amount of offset in the output signal of the first sensor is calculated in response to the calculated time interval and the calculated rotational-angle difference in cases where the calculated direction difference is equal to or smaller than a predetermined direction difference. The output signal of the first sensor is corrected into an offset-free signal in response to the calculated offset amount. The offset-free signal is integrated to generate a signal representing a final rotational angle of the vehicle body.

Title: Radio telephone equipment
Inventor: IKEDA MASATOSHI
IPC: H04B7/005
Filed: 1994-02-03
Abstract: In a radio telephone equipment which includes a portable radiotelephone and a booster, an output from the portable radiotelephone whose output level is set according to a level control signal transmitted from a base station is amplified with a preset amplification factor by an automatic gain control circuit provided in the booster. As a result, since the amplification factor of the amplifier in the booster and the portable radiotelephone are independently controlled, the booster can even be connected to a portable radiotelephone which is designed without considering that it will be connected to the booster.

Title: Modeling dough
Inventor: MILLER RICHARD A
IPC: C08K9/02
Filed: 1995-10-10
Abstract: A modeling dough comprising a polar polymeric resin, water, a gellant, and a filler provides a dough resistant to flaking, cracking, and crumbling. In the disclosed invention, the polymeric resin is gelled, thereby providing a water-based resin system that is not sticky yet very ductile. After the dough is air-dried, the components are bound into a solid, durable product. The filler accounts for a large portion of the volume of the dough, so the overall volume is not greatly affected by water loss upon drying. The dough is water-based and easy to wash from skin, carpets, and other surfaces. Dyes and pigments can be easily incorporated into the formula. The dried product is sandable and paintable.

Patent CA-2168896-A1 (CA)
Title: Method and apparatus for improving system performance in a data processing system
Inventor: HOPKINS MARTIN EDWARD
IPC: G06F9/38
Filed: 1996-02-06
Abstract: A computer processing apparatus includes a buffer called a decoded instruction buffer (DIB), which is used to store groups of commands representing instructions that can be executed in parallel. Each pattern in a DIB group may be an encoding of a long instruction termed a long decoded instruction (LDI).  The DIB works in conjunction with a conventional computer processing apparatus consisting of a memory system, an instruction queue, and an instruction dispatch unit feeding into a set of execution units.  When an instruction is not available in the DIB, this and subsequent instructions are fetched from the memory system into the instruction queue and executed in a conventional way, involving either a subset of availablefunctional units, or functional units dedicated to this purpose. Simultaneous with the execution of instructions by the conventional apparatus, a group formatter creates a set of LDIs, each of which is an alternate encoding of a set of the original instructions which can be executed in parallel. In constructing the LDIs, the group formatteranalyzes the dependency between instructions and instruction latency. Each set of LDIs constructed by the group formatter is saved in the DIB so that the next execution of the same set of instructions can be executed directly from the DIB on the full complement of functional units and will not require the effort of dependency and latency analysis.
