Publication number: 20030053888Abstract: A natural resin is dissolved in liquid oils and fats while a phosphate-based extreme pressure additive is evenly mixed in to prepare a paint composition. After the paint composition is applied to a high-strength hexagon head bolt (2) and a hexagon nut (3), centrifugal separation is performed for removal of excess paint composition and drying of the composition. Coating films can easily and quickly be formed. The high-strength hexagon head bolt (2) and the hexagon nut (3) thus provided with a coating film are fastened to each other by screwing. The heat and pressure generated during the fastening process cause the phosphate-based extreme pressure additive to react with the metal on the surface of the high-strength hexagon head bolt (2) and the hexagon nut (3) so that the phosphate-based extreme pressure additive in the film bonds to the metal. The coefficient of friction is reduced regardless of the smoothness of the surface of the high-strength hexagon head bolt (2) or the hexagon nut (3).Type: ApplicationFiled: August 27, 2002Publication date: March 20, 2003Inventor: Hikaru Takezawa

Publication number: 20030053890Abstract: Ends for cans are made in a single press, eliminating the need for separate shell and conversion presses, balancers, track work, and other equipment, as compared to existing can end manufacturing systems, while reducing floor space and capital investment requirements for installation of a new can end line. A sheet of end material or stock is introduced into the press and fed to a series of work stations. The sheet is maintained in a substantially continuous and void free state as the work stations perform forming operations on the sheet of material to form one or more ends therein. After the forming operation is complete, the end is ejected from the press. The maintenance of the sheet of material in a substantially continuous and void free state permits precise movement of the sheet through the press, and registration of the sheet relative to the tooling in the press.Type: ApplicationFiled: October 24, 2002Publication date: March 20, 2003Applicant: Rexam Beverage Can CompanyInventors: Timothy L.

Publication number: 20030053918Abstract: When a vacuum pump is installed over a vacuum system in a turned-over posture via a damper, a tension is applied upward to the vacuum pump by an elastic body one end of which is fixed to a fixed portion such as a ceiling, by which contraction caused by the weight of the vacuum pump and the atmospheric pressure applied when the interior of the damper becomes a vacuum is relaxed. Thereby, the decrease in vibration damping capacity of the damper caused by the compression of a rubber of the damper can be reduced. Also, when the vacuum pump is installed at the side of the vacuum system in a horizontal posture via the damper, a tension is applied upward to the vacuum pump by the elastic body one end of which is fixed to the fixed portion such as a ceiling to keep the horizontal posture of the vacuum pump. Thereby, the damper is prevented from being deflected by the weight of the vacuum pump, and thus high vibration absorbing capacity of the damper can be maintained.Type: ApplicationFiled: September 16, 2002Publication date: March 20, 2003Inventors: Akira Yamauchi, Takaharu Ishikawa

Publication number: 20030053928Abstract: Disclosed is a pressure heating apparatus which can surely prevent generation of cold spots inside the pressure vessel without using an excessive amount of steam and can shorten the required time necessary for pressurizing and heating. A circulation pipe for connecting a top side opening provided on the upper portion of a pressure vessel and a bottom side opening provided on the lower portion of the pressure vessel is provided outside the pressure vessel. A turbo blower is provided on a path of the circulation pipe and a steam supply pipe is connected thereto. Therefore, air inside the pressure vessel and steam supplied to the circulation pipe can be strongly agitated, thereby achieving uniformity of the temperature distributions and the steam density.Type: ApplicationFiled: August 12, 2002Publication date: March 20, 2003Applicant: Motoharu TAKANOInventor: Motoharu Takano

Publication number: 20030053932Abstract: The present invention relates to methods and forms of apparatus for sterilizing various objects with ozone. The contents of a container may be sterilized by attaching a lid with an ozone generator to the container and generating ozone. Clothing may be treated by attaching the clothing to an ozone generator with a housing in the shape of a clothes hanger and generating ozone. Alternatively, the ozone generator in the shape of a clothes hanger may be placed in a closet with clothing to be treated. The power supply for the ozone generator may be a portable power supply, or power may be supplied from an adapter from an electrical outlet.

Publication number: 20030053933Abstract: An analyzing apparatus has a partition dividing the interior of a housing into a lower space accommodating a power supply/control unit which generates heat and a duct and an upper space accommodating other units. Heat generated by cooling devices is exhausted to the exterior of the housing through the duct while the heat generated by the power supply/control unit is otherwise exhausted to the exterior. This construction makes it possible to achieve an improved heat exhaust efficiency and efficient cooling of a reaction unit provided in the upper space of the housing. A cover holding mechanism includes at least one each spring cam hinge and friction hinge.Type: ApplicationFiled: September 13, 2002Publication date: March 20, 2003Inventors: Takashi Miyake, Noriyuki Kitamura

Publication number: 20030053934Abstract: A microfluidic device which comprises two or more microchannel structures (set 1), each of which comprises a structural unit which comprises (i) one or more inlet microconduits, and (ii) an outlet microconduit downstream said one or more inlet microconduits, and (iii) a flow path for a liquid passing through either of said inlet microconduits and said outlet microconduit. The device is characterized in that each outlet microconduit in said two or more microchannel structures is a restriction microconduit. There may also be a microcavity between the inlet microconduit(s) and the restriction microconduit in each microchannel structure. Typically common flow control is used for driving a liquid flow within the device. The innovative design is useful for creating flow with low inter-channel variation with respect to the microchannel structures of the device.Type: ApplicationFiled: September 17, 2002Publication date: March 20, 2003Applicant: Gyros ABInventors: Per Andersson, Gunnar Thorsen, Gunnar Kylberg
