Publication number: 20020023436Abstract: In a multi cylinder internal combustion engine comprising a cylinder head internally defining exhaust passages extending from a plurality of combustion chambers defined in part by the cylinder head, the exhaust passages converging into a converging area also internally defined in the cylinder head, an oxygen sensor for detecting an oxygen concentration in exhaust gas is passed into the converging area substantially in parallel with a cylinder axial line. Thus, the oxygen sensor can be mounted relatively close to the combustion chamber while permitting the sensor to be uniformly exposed to the exhaust gas from the combustion chambers of an entire cylinder bank. Therefore, the oxygen sensor can be activated relatively quickly substantially without any warm-up, and can measure the oxygen concentration of the overall exhaust gas.Type: ApplicationFiled: August 23, 2001Publication date: February 28, 2002Applicant: HONDA GIKEN KOGYO KABUSHIKI KAISHAInventors: Toshihiro Akiwa, Masayuki Takahashi, Hiroshi Sakamoto

Publication number: 20020023444Abstract: An automated cold storage apparatus, and related method thereof, provides a sample process management system that is a revolutionary approach to the storage and retrieval regarding critical samples. The system—a significant technological breakthrough in laboratory automation—is the first ultra low temperature robotic system capable of being validated. Samples in containers are stored and retrieved robotically through an airlock climate-control chamber that is automatically dehumidified by a dry gas purge, such as a carbon dioxide or nitrogen purge or the like. This purge rapidly reduces ambient humidity to a desirable relative humidity (RH), e.g., less than about 15% RH, virtually eliminating the accumulation of frost. Microplates are systematically identified using barcode technology, for example. Once through the climate-controlled chamber, the containers (i.e., samples) are robotically transferred to the rotary mechanism.Type: ApplicationFiled: August 23, 2001Publication date: February 28, 2002Inventors: Robin A.

Publication number: 20020023450Abstract: A solar powered vapor compression refrigeration system is made practicable with thermal storage and novel control techniques. In one embodiment, the refrigeration system includes a photovoltaic panel, a variable speed compressor, an insulated enclosure, and a thermal reservoir. The photovoltaic (PV) panel converts sunlight into DC (direct current) electrical power. The DC electrical power drives a compressor that circulates refrigerant through a vapor compression refrigeration loop to extract heat from the insulated enclosure. The thermal reservoir is situated inside the insulated enclosure and includes a phase change material. As heat is extracted from the insulated enclosure, the phase change material is frozen, and thereafter is able to act as a heat sink to maintain the temperature of the insulated enclosure in the absence of sunlight. The conversion of solar power into stored thermal energy is optimized by a compressor control method that effectively maximizes the compressor's usage of available energy.Type: ApplicationFiled: April 19, 2001Publication date: February 28, 2002Applicant: Government of the United States of America, National Aeronautics & Space AdministrationInventors: Michael K.

Publication number: 20020023472Abstract: A method and a device for flexibly rolling a metal band by guiding the metal band through a roll gap formed between a first working roll and a second working roll, and by varying the size of the roll gap in such a way that band sections with a greater band thickness and band sections with a lesser band thickness are obtained over the length of the metal band. In the device and method, the time of contact between each point on the circumference of the first working roll and the metal band is shorter in duration than the time of contact between each point on the circumference of the second working roll and the metal band such that an asymmetric band thickness profile is obtained in a region of the band sections with a lesser band thickness.Type: ApplicationFiled: August 22, 2001Publication date: February 28, 2002Inventors: Peter Bohlke, Alexander Ebert, Andreas Hauger, Reiner Kopp

Publication number: 20020023474Abstract: A method and apparatus for forming a container component has a fixed stock plate and cut edge mounted on a base at a first level for forming a disk-shaped blank from a strip of sheet material. A blank and draw die is mounted at a second level which forms the disk-shaped blank into a shallow cup upon advancement of a punch assembly through the die. A profile pad is mounted at a third level on the base and imparts a profile on the bottom wall of the shallow cup as the punch assembly continues a downward stroke. An air stream ejects the profiled container component from the press at the third level.Type: ApplicationFiled: June 28, 2001Publication date: February 28, 2002Inventor: James A. McClung

Publication number: 20020023475Abstract: A device for forming components from billets having a thickness profile which is essentially symmetric to the central plane of the billet, i.e., the billet contains a thickness transition on both sides, and wherein the thickness transitions on both sided of the billet are transferred to one side of the formed such that the side of the formed component is planar. The forming surface of the forming device which faces the side of the billet that has a thickness transition in the formed state of the billet has a shape is adapted to the thickness transition to be realized, and the forming surface of the forming device which faces the side of the billet that becomes planar in the formed state is planar. Due to these measures, it is possible to transfer the thickness transitions that originally existed on both sides of the billet to one side of the billet in only one step.Type: ApplicationFiled: August 22, 2001Publication date: February 28, 2002Inventor: Andreas Hauger

Publication number: 20020023476Abstract: This invention relates to a hydraulic force modulator used in a power press to provide a predetermined force with a defined force applied by a ram of the press at defined incremental positions of the ram relative to a stationary part of the press. A moveable plate moves relative to a base plate. A resilient pneumatic bellows has one end sealingly mounted on the moveable plate. The resilient pneumatic bellows has an opposite end sealingly mounted on the base plate. A vessel is connected on one of the plates. A metering cylinder is mounted on the same plate as the vessel and is positioned within the vessel. A piston assembly is mounted in the metering cylinder. A piston rod has one end connected to the piston assembly and the opposite end connected to the other of the plates.Type: ApplicationFiled: May 24, 2001Publication date: February 28, 2002Inventors: Kenneth L. Smedberg, George J. Bozich, Ronald S. Boge
