    摘要: A drive belt includes at least one continuous band and a number of cross elements having a transversely curved saddle surface of saddle radius for interacting with an inwardly oriented main face of the continuous band that at a first lateral side thereof adjacent a pillar part of the element connects to a concavely recessed surface part through a first convexely curved transition surface part. The drive belt features include that: a transverse width of the continuous band is larger than that of the saddle surface; the saddle radius is essentially constant throughout the transverse width of the saddle surface; the saddle radius is smaller than a band radius of a transverse curvature of the band in an unloaded state thereof, irrespective of an amount of bending in the longitudinal direction of the band; and the first transition surface part forms a relatively sharp edge.

    摘要: A controllable attenuator includes a pair of collimators respectively connected to input and output fibers. A pair of reflection devices are respectively positioned behind the pair of collimators opposite to the corresponding input and output fibers. A U-like light path is defined among the pair of collimators and the pair of reflection devices. A neutral density filter is moveably positioned between the pair of reflection devices wherein a moving direction of the filter is preferably parallel to a longitudinal direction of the pair of collimators. An ND filter position indicator such as a potentiometer, is used to dynamically monitor attenuation setting.

    摘要: A dynamic fluid sealing system for a fuel injection valve employs sealing-fluid to separate a gaseous fuel and a second fluid in the fuel injection valve, thereby preventing leakage of the gaseous fuel into the second fluid. A pressure-balancing system, which includes a pressure-balancing device, reduces the pressure differential between the sealing-fluid and the gaseous fuel used in the injection valve. At the same time, the pressure balancing system dynamically balances the sealing-fluid pressure such that the sealing-fluid pressure is equal to or slightly greater than the pressure of the gaseous fuel within the injection valve. The pressure differential between the gaseous fuel and the sealing-fluid may be maintained throughout the operating range of engine speeds, engine loads, and fuel cut-off conditions so as to prevent leakage of compressible gaseous fuel into the second fluid. The reduced pressure differential between the gaseous fuel and the sealing-fluid also reduces leakage of sealing-fluid into the gaseous fuel.

    摘要: A four-wheel drive torque transfer mechanism splits torque from the transmission gearing section of a vehicle into a front-wheel torque and a rear-wheel torque, transmitting the front-wheel torque to the front-wheel drive shafts and the rear-wheel torque to the rear-wheel drive shafts. A central differential connected to the transmission gearing section distributes the torque from the transmission gearing section. A central differential limiting mechanism, provided between the input and output sides of the central differential, limits the rotary differential operation of the differential arrangement responsive to a control torque signal. Control gain values representing optimized turning characteristics are calculated for each of the turning conditions of the vehicle and stored in a memory. A controller for controlling the differential limiting mechanism reads the control gain values from the memory and calculates the products of detected turning conditions and the control gain values corresponding thereto. The controller further calculates the sum of the products and generates the control torque signal in accordance with that calculated sum.

    摘要: A device comprises first, second and third elements fabricated on a common substrate. The first element comprises an active waveguide structure comprising: a first portion supporting a first optical mode. The second element comprises a passive waveguide structure supporting a second optical mode. The third element, at least partly butt-coupled to the second portion, comprises an intermediate waveguide structure supporting intermediate optical modes. At least part of the second element is non-linear, supporting frequency conversion. A tapered waveguide structure in at least one of the second and third elements facilitates efficient adiabatic transformation between the first optical mode and one intermediate optical mode. No adiabatic transformation occurs between any intermediate optical mode and the first optical mode. Mutual alignments of the elements are defined using lithographic alignment marks.

    摘要: A bone anchor insertion device is disclosed for attaching a suture that is fixed to portion of soft tissue to a portion of bone. The device has a handle, a nosepiece connected to a distal end of the handle, a bone anchor connected to the nosepiece, and an actuator disposed on the handle for deploying the bone anchor. A suture ratchet or tensioning mechanism is disposed in the handle for tensioning suture which is associated with the bone anchor. This mechanism permits precise tensioning, while also permitting one-handed operation, thereby allowing the practitioner to use his or her other hand for other activities, such as camera operation or the like.
