Abstract: Memories which have new benign failure modes. The new failure modes are the omission-crash mode and the eventual-crash mode. Memories having either of thesemodes fail more benignly than memories having the omission failure mode, but unlike memories having the crash failure mode, memories with the novel failure modes may be used to construct gracefully-degrading fault tolerant objects. Implementations of memories with the new failure modes are disclosed, along withimplementations of fault-tolerant objects made from memories with the new failure modes.

Granted: 2007-01-09
Abstract: Synthetic melanins suitable for cosmetic uses are produced through oxidative polymerization of monomeric precursors that possess aromatic rings with ionizeable side groups. Agents that enhance adherence of the melanins to skin and hair are co-polymerized with the precursors to become part of the melanin molecules. Potential new precursors and adherence-enhancing agents are screened for efficacy by subjecting them to six separate synthetic procedures, and testing the resulting melanins for color, ultraviolet absorbance charcteristics, and substantivity (adherence) to skin and hair. Melanins of different colors can be blended together in cosmetic creams and lotions to complement the natural skin, eye, and hair colors of an individual. The synthetic procedures are amendable to industrial-scale production of cosmetic melanins. The materials reduce the incidence of solar damage to the skin.

Title: Refrigerating apparatus, and refrigerator control and brushless motor starter used in same
Inventor: HAMAOKA KOUJI
IPC: H02P6/08
Filed: 1996-03-14
Granted: 2000-12-19
Abstract: When a lock detector detects a locked state of a DC motor in a starting stage, a torque increasing circuit immediately selects a starting sequence pattern of an output torque that is greater in magnitude by one preselected step, and outputs the selected output torque to a starting sequence controller, so that a compressor can be restarted speedily without repeating starting failures. A compressor, driven by a DC motor, has a shell of an internal pressure approximately equal to the pressure of an inhalation gas. An inverter is provided to make the speed of the DC motor variable. A rotational frequency setting circuit sets the rotational frequency of the DC motor to a frequency that is not greater than the frequency of a commercial power source when the internal temperature of a refrigerator is stabilized. By this construction, the power consumption can be remarkably reduced.

Inventor: OBREJANU MARCEL
IPC: E21B43/38
Filed: 1997-07-16
Granted: 2001-11-27
Abstract: The efficiency of progressing cavity pumps is drastically reduced if the liquid being pumped contains large volumes of gas.  To alleviate this problem a gas separator is provided which can be attached to the suction of a downhole pump to remove gas from the liquid being pumped prior to the liquid entering the pump inlet.  The separator comprises an elongate housing having an annular chamber with guides which direct the liquid gas mixture to flow in an annular path from the inlet to the outlet end.  During this flow centrifugal forces act to displace the gas content to the central region from which it is removed via a separate central gas outlet so that liquid delivered to the pump inlet is greatly reduced in its gas content.

Abstract: A method is described for labeling containers (22, 30 and 44) with a label (12, 32 and 40) that facilitates a de-labeling process. During the labeling process, a frangible region (34 and 42) is formed on the label (12, 32 and 40) which is then applied to containers (22, 30 and 44). After consumer use, the labeled containers (22, 30 and 44) are collected for de-labeling. In the de-labeling process, a mechanical force is applied to the frangible region (34 and 42) which causes the label (12, 32 and 40) to flag outwardly from the container (22, 30 and 44). A separating device then removes the label (12, 32 and 40) from the container (22, 30 and 44). The de-labeled container (22, 30 and 44) may then be cleaned for reuse and provided with a fresh label.
