IPC: F01M1/18
Filed: 2001-03-16
Granted: 2007-12-26
Abstract: The oil of a diesel engine is exchanged for each running at a pre-determined distance. The oil exchange is carried out by estimating the amount of soot generation by combustion based on a running distance, and is not very accurate. The oil is exchanged earlier. Therefore, the oil is consumed wastefully and a cost of maintenance is increased. There has been found a phenomenon (correlation) in which the degree of oil degradation in the diesel engine is determined depending on an injection end point in such an injection way as to cause the injection end point to be earlier than a specific point (TB) and is determined depending on the injection amount after the specific point and the injection end point in such an injection way as to cause the injection end point to be later than the specific point. When the amount of soot generation is obtained by utilizing the phenomenon, the degree of oil degradation can be obtained more accurately than that in the conventional art. In every fuel injection, it is judged whether the injection end point is set before or after the specific point (Step 8), and a current injection degradation value is obtained by using a corresponding map (Step 9, 10). A cumulative added value is obtained to judge the oil degradation. <IMAGE>

Abstract: PROBLEM TO BE SOLVED: To provide a high-precision sine-wave generating circuit which is not influenced by temperature variation. SOLUTION: When only a control signal D3 is turned on, a transistor Q27 turns on to change a capacitor C, and further, when a control signal D4 is turned on, a transistor Q37 turns on to charge the capacitor C. When only a control signal D1 is turned on, a transistor Q7 turns on to discharge the capacitor C, and further when a control signal D2 is turned on, a transistor Q17 turns on to discharge the capacitor C. When the control signals D1 and D6 are switched in specified timing, a sine-wave output Vo can be generated. At this time, the magnitude of the discharging current is set by the output of a temperature sensor 3 and transistors Q6, Q16, Q26, and Q36 differing in emitter area ratio, and then a high-precision sine wave can be generated which is hardly influenced by temperature variation.

Abstract: Featured is a pressure control regulator including a housing, a sealing member disposed within the housing, a flexible member and a biasing mechanism. The housing includes at least one inlet aperture and at least one outlet aperture, each inlet aperture being fluidly coupled to a first pressure source and each outlet aperture being fluidly coupled to a second pressure source, the first and second pressure sources being at different pressures. The flexible member extends between the sealing member outside surface and the housing inner surface so as to form a pressure boundary therebetween and to divide the housing interior into first and second compartments. The biasing mechanism, being responsive to pressure within the second compartment, acts on the sealing member so the sealing member is in one of an open position, when the second compartment is greater than a predetermined pressure value, or a closed position, when the second compartment pressure is at or below the predetermined pressure value. A portion of the housing in fluid communication with the second pressure source, also includes a mechanism to restrict fluid flow to or from the second compartment such that the second compartment pressure changes when fluid flow in either direction occurs for a time more than a predetermined period of time and remains effectively unchanged when such fluid flow time is less than the predetermined period of time. In a more particular embodiment, the second pressure source is a suction source and the regulator is a suction pressure regulator.

Abstract: A method for controlling the charging and discharging phases of a backup capacitor for a data storage medium has the step where the backup capacitor is first discharged to a defined voltage level before it is charged. The capacitor is discharged using a constant current. This ensures that the charging current for the backup capacitor cannot be used to identify what the charge-state of the capacitor was before discharging. Therefore, it is no longer possible to infer the currents that flowed during security-related arithmetic operations in a data processing unit. In one advantageous circuit configuration, a constant current source is formed by a current-mirror circuit, and a comparator is used to compare the voltage on the backup capacitor with a bandgap reference.

An inner chamber preserves a vacuum or substantial under pressure when the inlet is sealed by a blocking member adjacent to the inlet. The blocking member is elastic and has a flow permitting configuration which admits the body substance into the inner chamber and a flow preventing configuration which blocks the inlet from the inside of the chamber when the pressure difference has been equalized.

Abstract: The present application is directed to the use of X-ray contrast media that act as universal antigens that are labeled herein as “pseudoantigens.” X-ray contrast media have the potential to exist in an aggregated state that is greater in increased concentrations. In this aggregated state, contrast media assume the role of multivalent antigens and can successfully compete with any other antigens involved in antibody-antigen reactions that lead to anaphylaxis. In this competition, the large quantity of contrast media serves to inhibit the adverse effects of antibody-antigen reactions without the contrast media itself creating antibodies or creating toxicity problems.
