Publication number: 20040118192Abstract: The following invention pertains to the introduction of a gas (or fluid) around a SPM probe or nanotool™ to control chemical activity e.g. oxygen to promote oxidation, argon to inhibit oxidation or clean dry air (CDA) to inhibit moisture to control static charging due to the action of the probe or nanotools and to provide vacuum at and around the tip and substrate area.

Publication number: 20040118193Abstract: A profiler or scanning probe microscope may be scanned across a sample surface with a distance between them controlled to allow the sensing tip to contact the surface intermittently in order to find and measure features of interest. The distance is controlled so that when the sensing tip is raised or lowered to touch the sample surface, there is no lateral relative motion between the tip and the sample. This prevents tip damage. Prior knowledge of the height distribution of the sample surface may be provided or measured and used for positioning the sensing tip initially or in controlling the separation to avoid lateral contact between the tip and the sample. The process may also be performed in two parts: a fast find mode to find the features and a subsequent measurement mode to measure the features. A quick step mode may also be performed by choosing steps of lateral relative motion to be smaller than 100 nanometers to reduce probability of tip damage.Type: ApplicationFiled: December 5, 2003Publication date: June 24, 2004Inventors: Thomas McWaid, Peter Panagas, Steven G.

Publication number: 20040118194Abstract: An engine starter motor tester applies power to a motor under test at the level normally applied while that motor is installed in a vehicle and monitors the ripple in the driving current. The ripple rate, scaled by the number of windings used in the construction of the motor, provides a direct reading of the shaft speed of the unloaded motor. This number allows a valid inference concerning the state of health of the motor, and is more certain than an estimate for an unloaded motor based on operator experience and motor “sound”. A complete test apparatus includes a stored lookup table, allowing the user to key in a product brand and model number and read directly both the RPM and the test apparatus's rating of the motor under test, expressed in terms such as percentage of life remaining.Type: ApplicationFiled: December 20, 2002Publication date: June 24, 2004Applicant: SPX CorporationInventor: Kurt Raichle

Publication number: 20040118200Abstract: A device for measuring the flow of a fluid has a primary duct and a bypass arranged in series to the primary duct.

Publication number: 20040118230Abstract: A force sense imparting type input apparatus includes an operation portion, an actuator for imparting a force sense to the operation portion, a position sensor for detecting an operating direction and an operating quantity of the operation portion, a temperature sensor for detecting a temperature of the actuator, and a controller for acquiring a position signal and a temperature signal and outputting driving signal of the actuator. A correction control portion provided to the controller determines a calorific value of the actuator from the temperature signal, then a correction value of driving power supplied to the actuator from the calorific value so calculated, adds a correction value of driving power of the actuator at the time of a normal operation and decides driving power of the actuator at the time of over-heat.Type: ApplicationFiled: December 3, 2003Publication date: June 24, 2004Applicant: Alps Electric Co., Ltd.Inventors: Yoshio Sanpei, Kaiji Nonaka, Ayumu Kobayashi, Ken Shibazaki, Noriyuki Fukushima

Publication number: 20040118231Abstract: A disturbance-cancellation system and method is provided that facilitates the adaptive cancellation of periodic disturbances. The disturbance-cancellation system and method includes a pair of control moment gyroscopes (CMGs) arranged together as a scissored pair. The scissored pair of CMGs is used to create a periodic torque with a controllable amplitude and frequency. The periodic torque created by the CMGs is adaptively controlled to cancel out periodic disturbances in the system. The system and method creates a periodic torque with a controllable amplitude and frequency by rotating the inner-gimbal assemblies of the CMGs in opposite directions at substantially equal phase and angular velocity. Amplitude matching can be achieved by adjusting the rotor spin rate. The steady-state constant motion results in a periodic torque along the output axis of the scissored pair, while components of torque along axes orthogonal to this one cancel out.Type: ApplicationFiled: December 19, 2002Publication date: June 24, 2004Inventor: Mason A. Peck

Publication number: 20040118232Abstract: The invention relates to a motor-driven pivoting device for a support plate that can cooperate with a positioning motor and be pivoted kinematically in relation to a holder, which is fixed to the object. In order to receive a mirror, the plate is provided with a fixed hollow spherical area on its rear side, which is directed away from the mirror, for stable mounting with a compact inbuilt part-turn actuator, mounted with the ability to pivot between two rigidly interconnected spherical surfaces along the generated surfaces thereof. The outer of the two interlocking spherical surfaces of the dual shell holder is embodied in the form of an assembly cap. Its inner surface is fitted out as a carrier for a device with a motor and a set of gears engaging with the gearing that moves radially to engage with the inner area of the device carrier along a generatrix of the inner generated surface of the hollow area.Type: ApplicationFiled: February 11, 2004Publication date: June 24, 2004Inventors: Wilhelm Wolf, Josef Boegelein, Wolfgang Seiboth, Heinrich Lang

Publication number: 20040118233Abstract: A transfer case for a vehicle having two-wheel drive and four-wheel drive operating modes operatively established by a drive transfer mechanism that is selectively employed to interconnect a main power drive shaft construction for the drive of a first set of wheels with an auxiliary drive shaft for the drive of a second set of wheels. The drive transfer mechanism includes a clutch assembly package comprising a control rod supported for movement in a direction coaxial to the longitudinal axis of the auxiliary drive shaft. The clutch assembly includes a clutch collar supported within the auxiliary drive shaft on the control rod for movement therewith to alternately connect and disconnect the power shaft with the auxiliary drive shaft. For multi-ratio case operation, the power shaft construction may have an input and output power shaft sections that are selectively interconnected by a planetary gear set and a speed shift collar.Type: ApplicationFiled: December 19, 2002Publication date: June 24, 2004Inventor: David Robert Weilant

Publication number: 20040118236Abstract: The invention provides a gate type shift lever apparatus in which a solenoid type shift lock mechanism is built at a position engaging with a shift lever (3) of a position P. This shift lock mechanism is constituted by a solenoid (12) which is turned on at a time when a brake pedal is stepped on, a slider (11) which is closely contacted with the solenoid (12) by a spring (14) at a normal time, and a shift lock plate (13) which is pivoted onto the slider (11). The shift lock plate (13) is oscillated along with a selecting operation of a shift lever (3). When a select operation of the shift lever (3) is carried out in the case that the brake pedal is stepped on and the solenoid (12) is in an on state, the slider (11) is adsorbed by the slider (12) so as to stay at a fixed position, so that only the shift lock plate (13) oscillates so as to move the shift lever (3) from the position (P).Type: ApplicationFiled: May 30, 2003Publication date: June 24, 2004Applicant: MANNOH KOGYO CO., LTD.Inventor: Akira Tazai

Publication number: 20040118237Abstract: A bywire system shift lever device for vehicles includes a base member, a lever member to be driven by an operating element, an electric motor provided on the lever member, a transmission mechanism to transmit a rotation of a rotating shaft to the lever member, a first position detecting sensor for supplying first position signals representing the operating angle of the lever member, and a second position detecting sensor for supplying second position signals. Consequently the electric motor is controlled by the second position signals and thus a predetermined sensory resistance is provided to the operating element by a force of the rotating shaft of the electric motor applied via transmission mechanisms.Type: ApplicationFiled: March 5, 2003Publication date: June 24, 2004Inventor: Hironori Kato
