Patent number: 6877340Abstract: It is an object of the present invention to reduce the constraint that the density ratio is constant as small as possible, and to obtain high power recovering effect in a wide operation range by using an expander which is operated in accordance with a flowing direction of refrigerant. An expander used in a refrigeration cycle uses carbon dioxide as refrigerant and has a compressor, an outdoor heat exchanger and an indoor heat exchanger. The expander comprises a cylindrical cylinder, a rotor which rotates in the cylinder, a vane which divides an expansion space formed between an inner peripheral surface of the cylinder and an outer peripheral surface of the rotor into a plurality of spaces, and a vane groove provided in the rotor for accommodating the vane therein. The vane groove is provided with a back pressure chamber which pushes the vane against the inner peripheral surface of the cylinder, and the refrigerant in the supercritical state is introduced into the back pressure chamber.Type: GrantFiled: September 9, 2003Date of Patent: April 12, 2005Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Akira Hiwata, Noboru Iida

Patent number: 6877341Abstract: Disclosed are a method and system for removing scratches from a planar panel of translucent or transparent material, such as glass, without removal from its frame. A heat source supplying a controlled amount of heat is moved across the surface of the planar panel at a controlled velocity and at a controlled distance from the surface so as to progressively melt a thin surface layer at portions of the surface heated by the moving heat source. The melted material re-flows under surface tension to smooth scratches in the surface layer. Movement of the heat source is repeated over different portions of the surface until all scratched areas have been treated. The treated panels have a smooth surface with scratches removed, and have good optical and structural qualities.Type: GrantFiled: January 28, 2002Date of Patent: April 12, 2005Assignee: The Trustees of Columbia University in the City of New YorkInventor: Shane Y.

Patent number: 6877342Abstract: A controlled method for an energy-saving and energy-releasing air conditioning discloses the energy-saving and energy-releasing actions performed by the two adjoined heat exchangers of the storage means. The feature of this design is to meet refrigerating and heat-produced requirements by using the controlled method of the present invention. Automatically adjusting the refrigerant flow rates of the first and the second circular refrigerant loops can place it into the optimum operational condition while central air conditioner is either under high loading or under low loading condition.Type: GrantFiled: July 3, 2003Date of Patent: April 12, 2005Assignee: Cohand Technology Co., Ltd.Inventor: Kuo-Liang Weng

Patent number: 6877343Abstract: In a magnetic recording medium, surface roughness of a glass substrate and the variation of the surface roughness are suppressed to the predetermined range. Namely, the surface roughness (Rmax, Ra, Rq) and the relation (Rmax/Ra) between Rmax and Ra are restricted to the predetermined range. In this event, Ra is representative of a center-line mean roughness, Rmax is defined as a maximum height representative of a difference between a highest point and a lowest point and Rq is representative of a root mean square roughness. Thereby, crystal grains of an underlying layer and a magnetic layer formed thereon are equalized. Specifically, the surface roughness is specified by Rmax?15 nm, Ra?1 nm and Rq?1.5 nm. Further, the ratio between the surface roughness Rmax and the surface roughness Ra is specified by Rmax/Ra?30.Type: GrantFiled: October 28, 2002Date of Patent: April 12, 2005Assignee: Hoya CorporationInventors: Tsuyoshi Watanabe, Koji Takahashi, Masao Takano

Patent number: 6877344Abstract: An optical fiber is prepared by applying a liquid electron beam-curable resin composition to a bare optical fiber or a coated optical fiber having a primary or secondary coating on a bare optical fiber, irradiating electron beams to the resin composition on the optical fiber for curing while the optical fiber passes a zone under substantially atmospheric pressure, and providing a magnetic field and optionally an electric field in the zone for thereby improving the efficiency of electron irradiation. The method can comply with the increased drawing speed of the bare optical fiber and does not detract from the transmission properties of the optical fiber.Type: GrantFiled: February 20, 2002Date of Patent: April 12, 2005Assignee: Shin-Etsu Chemical Co., Ltd.Inventors: Toshio Ohba, Nobuo Kawada, Masaya Ueno

Patent number: 6877345Abstract: A padlock for luggage that can be operated by setting a combination or by inserting and turning a key is provided with an indicator that normally displays a first state when the lock being used in a normal way as a combination operated luggage padlock, but which displays a second state if the padlock has been opened by government inspectors utilizing a key for purposes of inspecting contents of the luggage. The indicator can be reset from a display of the second state to a display of the first state only after the padlock has been opened utilizing a combination known to the owner. The indicator is movable between first and second positions, and has first and second surfaces of different appearance, one or the other of which is displayed through a window of the housing depending on whether the indicator is in the first position or the second position.Type: GrantFiled: August 5, 2003Date of Patent: April 12, 2005Assignee: The Eastern CompanyInventors: Michael O. Misner, Jian-Bing Lu

Patent number: 6877346Abstract: A walk-in freezer door system has a doorjamb with sheets of metal covering a body of thermal insulation. A door is mounted to the doorjamb. A deadbolt housing is mounted to the outside of the doorjamb with a deadbolt mounted for reciprocal movement within the housing between a door locked and a door unlocked position. A handle is rotatably positioned inside of the doorjamb from which a shaft extends into the deadbolt housing and into operative association with the deadbolt. A longitudinal portion of the handle shaft is made of a low thermal conductive plastic. A keeper is mounted to the door in a position to receive the deadbolt with the door located within the doorjamb.Type: GrantFiled: January 15, 2002Date of Patent: April 12, 2005Assignee: Kason Industries, Inc.Inventor: Burl Finkelstein

Patent number: 6877348Abstract: The invention relates to a closing device for a vehicle comprising a lock, a drive for determining the locking state of the locking device, by means of which the locking device may be placed in at least four different locking states and a rotating shaped disc on the drive, which may be rotated by the drive to determine the individual locking states, whereby the individual locking states are each assigned a particular angular position for the shaped disc. According to the invention, the shaped disc (1) is of such a form that said disc may be taken from each angular position, corresponding to one of the various states (V, K, S) and different to the unlocked state (E), without a third locking state occurring on performing the above.Type: GrantFiled: September 4, 2001Date of Patent: April 12, 2005Assignee: Brose Fahrzeugteile GmbH & Co.
