Abstract: A bearing ring comprises a raceway for a rolling member as well as at least one lateral rim for axially guiding the rolling member. To produce the bearing ring a notch is introduced into a running surface of the bearing ring which faces the rolling member. A final contour of the bearing ring is created by means of a hard turning process.

Abstract: A memory circuit for an inkjet print head having a plurality of memory cells switchably connected to a source and configured in an array, wherein at least one of the memory cells is a reference memory cell and at least one of the remaining cells are data memory cells, and at least one sense amplifier adapted to compare at least one of a current and voltage received from the reference memory cell with at least one of a current and voltage received from one of the data memory cells and generate an output based on the comparison.

Abstract: A method of error detection in an inkjet printing apparatus having a host coupled to a print head. The method comprises the acts of communicating a first data stream between the host and the print head, inserting a reference data stream into the first data stream, and validating the first data stream based on the reference data stream.

Abstract: An improved heater chip for an ink jet print head, the chip including an active heater array and an inactive heater array located adjacent to and extending away from the end of the active heater array. The inactive heater array provides a region adjacent the end of the active heater array that is substantially planar, and also provides a plurality of current paths which reduces energy differences between heater resistors adjacent the end of the active heater array and other heater resistors in the heater array.

Abstract: A low-profile ink jet cartridge assembly for an ink jet printer. The low profile ink jet cartridge assembly includes a substantially rectangular ink jet cartridge body having a printhead side, opposing side surfaces attached to the printhead side and a length, a height, and a width, wherein the length is greater than the height and the width. A printhead containing a semiconductor substrate is attached to the printhead side of the ink cartridge. A flexible circuit having a width, a length, a first edge along the length thereof, a second edge along the length thereof, first printer contact pads along at least a portion of the length thereof adjacent the first edge, and second printer contact pads along at least a portion of the length thereof adjacent the second edge is attached to the ink cartridge on the opposing side surfaces of the cartridge body.

Abstract: An apparatus for controlling a model railroad locomotive includes a Digital Command Control (DCC) decoder and a power switch. The power switch selectively connects the railroad locomotive's motor to either the decoder or directly to an energy source, such as the tracks, but not both the decoder and the energy source simultaneously. When the motor is connected directly to the energy source, rather than through the decoder, the model railroad locomotive speed and direction is determined by the magnitude and polarity of the voltage applied. The motor may alternatively be powered through the decoder by actuating the power switch. The decoder receives electrical energy as an input, and converts the energy to deliver as an output a variable electric motor drive power source. In addition to receiving energy as an input, the decoder also receives electrical signals representative of an operator's control instructions.

Abstract: A vibratory conveyor for advancing stacked wafer-like articles in an edgewise upstanding orientation includes a vibratory trough having a vibratory base portion of a width which is less than the width of the entire vibratory trough. The conveyor further has a non-vibratory, elongated base component situated adjacent the vibratory base portion and having a width which, together with the width of the vibratory base portion constitutes substantially the width of the entire vibratory trough. In response to an operational parameter of the vibratory conveyor, the articles are caused to be disengaged from the vibratory base portion and engaged solely by the non-vibratory base component, whereby conveyance of the articles is interrupted.

Abstract: A vibration damper for vehicles is described, the damper curve of which is required to be arbitrarily variable, to enable the damping to be adapted optimally to driving conditions. For this purpose, the invention has a vibration damper in which a regulating member actuable by an actuating device can be pressed with variable force against at least one spring washer of a valve closure element of a damping valve arranged in the damper piston. The contact pressure of the regulating member is arbitrarily variable and the regulating member can be pressed progressively against the spring washer of the valve closure element upon an increase of force in the radial direction.

Abstract: A suspension-strut mounting for installation between a shock-absorber strut or spring strut and a vehicle body spring-supported with respect to the axles, with at least one connecting element having elastically resilient and vibration damping properties which is connected both with the body as also with the piston rod of a shock-absorber of the shock-absorber strut or spring-strut; an additional vibration damper is provided in parallel with the connecting element.
