Publication number: 20040149016Abstract: An evaporated fuel purge system has a fuel tank, an adsorption filter and a purge control valve. The evaporated fuel purge system is pressurized and depressurized through a venting flow path by a pump, so that the state of leakage therefrom is thereby inspected. For this inspection, a motor unit for driving the pump which applies or reduces pressure, an in-vehicle battery and a voltage control circuit which controls a battery voltage to a predetermined voltage and supplies the motor unit with a current are provided. A switchover valve is integrated with the pump, the motor and the like into a single module.Type: ApplicationFiled: January 16, 2004Publication date: August 5, 2004Applicant: DENSO CORPORATIONInventors: Masao Kano, Yoshichika Yamada, Mitsuyuki Kobayashi, Koichi Inagaki

Publication number: 20040149017Abstract: A pump housing contains a pump that draws fuel from an underground storage tank to deliver fuel to fuel dispensers in a service station environment. The pump is coupled to a double-walled riser pipe that carries the fuel from the underground storage tank to the pump. The double-walled fuel piping contains an inner space that carries the fuel and an outer annular space that captures any leaked fuel from the inner space. The outer annular space is coupled to a vacuum created by the pump to determine if a leak exists in the outer annular space. An alternate submersible turbine pump has a double-walled housing with a pressure sensor disposed in the interstitial space of the double-walled housing. A vacuum may be created therein to determine if leaks are present in the housing of the submersible turbine pump.Type: ApplicationFiled: November 6, 2003Publication date: August 5, 2004Inventors: Ray J.

Publication number: 20040149018Abstract: A test apparatus and method for predicting the minimum runnable flow of a curtain coating fluid by forcing the coating fluid out of a small round tube opening with less flow rate than is required for momentum to exceed the contracting forces of surface tension. The minimum flow rate is a measure of the combined effects of the surface tension, viscosity, elasticity, and dilitant behavior of the coating fluid which influence the stretch and acceleration of the fluid, that in turn, characterize the runnability of the fluid for a full scale curtain coating process. The velocity of the coating as it lands can also be determined from the flow rate and acceleration to predict whether the coating fluid will run or not before it is applied to a web or substrate.Type: ApplicationFiled: December 30, 2003Publication date: August 5, 2004Inventor: John A.

Publication number: 20040149019Abstract: A conventional Couette viscometer is transformed to measure yield point, also known as yield stress, and other rheology of various fluids, including ones with particulates. A rotating viscometer includes a driven portion, a responsive body, a standard spring, and a plurality of fins. The fins have predetermined shapes such that the rotating viscometer and the standard spring, connected to the responsive body having at least a portion of the fins, are sensitive to detect yield stress of a test fluid composition in response to a selected rotation imparted to the driven portion. A method of measuring yield stress includes operating a standard rotating viscometer modified with a plurality of intermeshing fins such that a standard spring of the standard rotating viscometer responds to a torque that is related to yield stress and that is imposed by a stressed test material on a portion of the fins connected to the spring.Type: ApplicationFiled: January 30, 2003Publication date: August 5, 2004Inventors: Johnny W. Johnson, Ronnie G. Morgan

Publication number: 20040149020Abstract: Disclosed herein is an alcohol content and temperature measuring instrument which is simply composed of a mug, an embolism an observation window, and a thermograph and a measuring tub. The measurement of alcohol concentration in a particular liquid can be measured according to Torricelli's law and Archimedes principle, while learn about the temperature of the liquid from the thermograph.Type: ApplicationFiled: February 5, 2003Publication date: August 5, 2004Inventors: Shun-Tsung Lu, Ta-Wei Lu

Publication number: 20040149021Abstract: A method for enhancing information derived from acoustically inspected samples comprises deriving an acoustic image of a sample, and generating a visual superposition of one or more additional images. The additional images are selected from the group consisting of an optical image, a second acoustic image in a different sized field of view form said acoustic image, an infrared image, an X-ray image, and an electron beam image.Type: ApplicationFiled: August 22, 2001Publication date: August 5, 2004Inventors: Lawrence W.

Publication number: 20040149022Abstract: A method for detecting and reducing an offensive noise in a vehicle having an engine. A noise is sensed in an area of interest of the vehicle. The area of interest contains a plurality of parts capable of generating the offensive noise. The sensed noise is analyzed to determine components of the noise. The offensive noise is determined based on the sensed noise and the determined noise components. Which one of the plurality of offensive noise generating parts is generating the offensive noise is determined. The offensive noise generating part is affected to reduce the offensive noise coming therefrom and thereby reducing the offensive noise in the area of interest of the vehicle.Type: ApplicationFiled: February 3, 2003Publication date: August 5, 2004Applicant: Honda Giken Kogyo Kabushiki KaishaInventors: Tony Witer, Kelly Hennessy, Chris Sullivan
