Patent number: 6332710Abstract: A multi-channel remote diode temperature sensor that receives current flow across a plurality of remote diodes on a plurality of channels at a single negative data pin, is small in size and has reduced noise coupling between channels at the common negative data pin. The noise coupling of the multi-channel remote diode temperature sensor is minimized by placing an output of a low impedance buffer in electrical communication with the negative data pin. The voltage produced by the low impedance buffer automatically stabilizes the common mode voltage at the negative data pin. The size is minimized by configuring all channels of the multi-channel remote diode temperature sensor to share the sole negative data pin, thereby reducing pin count.Type: GrantFiled: July 24, 2000Date of Patent: December 25, 2001Assignee: National Semiconductor CorporationInventors: Mehmet Aslan, Richard Henderson

Patent number: 6332750Abstract: Successive palletized stacks of blanks in a layer of such stacks on a penetrable support of cardboard or the like are lifted off the support by a substantially horizontal plate- or blade-like implement which is caused to penetrate between the upper side of the support and the underside of a selected stack prior to lifting of the selected stack off the support for transfer onto a conveyor or into a blank converting machine, such as a cigarette packing machine. An optical or other suitable monitoring unit has one or more sensors carried by the implement such that they share the movements of the implement to detect, and to effect the generation of defect signals in response to the detection of, improper operation of the apparatus, such as the penetration of the implement through and subsequent lifting of a portion of the support with a selected stack.Type: GrantFiled: November 19, 1997Date of Patent: December 25, 2001Assignee: Topack Verpackungstechnik GmbHInventors: Knut Donner, Hans-Jürgen Hoppe, Uwe Keil

Patent number: 6332751Abstract: In centering a transfer device so that tweezers of the transfer device transfer a substrate to a predetermined delivery position on a spin chuck when the substrate is delivered to a coating unit by means of the transfer device, the substrate is transferred onto the spin chuck in the coating unit by means of the tweezers, a positional deviation amount of the substrate with respect to the delivery position on the chuck is detected by a detecting device, a positional deviation amount of the tweezers is computed based on this detection value, and a position at which the tweezers deliver the substrate is corrected based on the positional deviation amount of the tweezers. Thus, centering of the substrate transfer device can be performed automatically in a short time.Type: GrantFiled: March 30, 2000Date of Patent: December 25, 2001Assignee: Tokyo Electron LimitedInventors: Seiji Kozawa, Naruaki Iida, Jun Ookura

Patent number: 6332752Abstract: A turbo-molecular pump of high safety and reliability has been developed so that if an abnormal condition should develop on the rotor structure, it will not lead to damage to the stator or pump casing to cause loss of vacuum in a vacuum processing system. The turbo-molecular pump comprises a pump casing housing a stator and a rotor therein, a vane pumping section and/or a groove pumping section comprised by the stator and the rotor, and a constriction releasing structure for releasing constriction of at least a part of the stator when an abnormal torque is applied to the stator by the rotor.Type: GrantFiled: June 25, 1998Date of Patent: December 25, 2001Assignee: Ebara CorporationInventors: Tetsuma Ikegami, Matsutaro Miyamoto, Hiroyuki Kawasaki

Patent number: 6332754Abstract: A steam turbine comprises, in combination, at least two of a high pressure turbine section, an intermediate pressure turbine section and a low pressure turbine section in a single turbine casing and the steam turbine generally satisfies such design requirements as: a main steam pressure of 100 kg/cm2 or more; a main steam temperature of 500° C. or more; a rated output (power) of 100 MW or more; and a unit rotated at a rotation speed of 3,000 rpm equipped with a last-stage movable blade of the turbine having an effective blade length of 36 inches or more, or a unit rotated at a rotation speed of 3,600 rpm equipped with a last-stage movable blade of the turbine having an effective blade length of 33.5 inches or more. In such steam turbine, a turbine exhaust chamber of the low pressure turbine section has a structure extending towards both sides of a transverse direction of the turbine casing, towards the upper side thereof or in the axial direction thereof.Type: GrantFiled: April 3, 2000Date of Patent: December 25, 2001Assignee: Kabushiki Kaisha ToshibaInventors: Minoru Matsuda, Masataka Kikuchi, Nobuo Okita, Kouichi Kitaguchi

Patent number: 6332755Abstract: The present invention provides a blower that improves the P-Q characteristic and reduces noise. The apparatus is a blower that sucks air inside through slits (6) provided in an annular wall (2), wherein the blade thickness near a blade end s is progressively reduced toward the front end, and the location F of the maximum thickness gradually moves back toward a blade trailing edge side u2 so as to make the blade advance angle near the front end larger than in other locations. In addition, the width of a slit is made wider in sections near a spacer than in other sections. Alternatively, notches are provided in the outer perimeter of annular plates near the spacers so as to reduce the radial length of the annular plates. This arrangement improves the P-Q characteristic and reduces noise.Type: GrantFiled: July 27, 2000Date of Patent: December 25, 2001Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Hiroyasu Fujinaka, Shigeru Otsuka

Patent number: 6332756Abstract: The multi-functional motion converting unit can be compact, efficient and inexpensive. In the motion converting unit of the present invention, a holding member is provided in a plane. A swing fin is extended, from the holding member, in a direction perpendicular to the plane. The swing fin has a first face and a second face, which cross a swing direction of the swing fin. The faces are capable of guiding a flow of a fluid. A swing width of a free end of the swing fin is wider than that of a base end thereof when the holding member is moved in the direction parallel to the plane. Guiding means guides the movement of the swing fin with the holding member.Type: GrantFiled: January 6, 2000Date of Patent: December 25, 2001Assignee: Yugen Kaisha SozoanInventor: Ken Yanagisawa

Patent number: 6332757Abstract: A valve housing has a communication passage communicating a suction port of the compressor with a crank chamber of the compressor. A valve element opens and closes the communication passage, and a spring member resiliently biases the valve element toward the closed position. A pressure actuated unit moves the valve element toward the open position by a suction pressure of the compressor. The spring member includes a spring made of a temperature responsive material. The spring decreases in its resilient force in an opening direction of the valve element with increase of an outer-air temperature. The spring member has a primary spring made of an ordinary resilient material for resiliently biasing the valve element toward the closed position and a correction spring made of a material having a temperature positive characteristic. The correction spring provides a correction spring force smaller than a primary force of the primary spring in the opposite direction to the primary force.Type: GrantFiled: May 4, 2000Date of Patent: December 25, 2001Assignees: Kabushiki Kaisha Saginomiya Seisakusho, Kabushiki Kaisha Toyoda Jidoshokki SeisakushoInventors: Morio Kaneko, Ichiro Ohkawara, Masaki Ota, Ken Suitou, Kenta Nishimura, Taku Adaniya

Patent number: 6332758Abstract: Air-bearing fan includes a dust-proof cover, a fan blade structure, a magnet, a stator, a sleeve, an electronic circuit board, a housing and a thrust disk. While the fan blade structure is rotating, air can be induced into a ring-shaped gap so that an air-bearing is formed. And, air is also induced into a thrust gap and forms a thrust bearing. Therefore, this invention significantly reduces the noise and increases the fan's rotating speed, fan capacity and life.Type: GrantFiled: February 24, 2000Date of Patent: December 25, 2001Assignee: Hsin-Mao HsiehInventors: Ping-Huey Tang, Chi-Wei Tien, Hsin-Pu Chen
