A torque measuring apparatus is described that comprises a chassis, a reversible electrical motor having a motor housing and a rotatable output shaft projecting from one end of said motor housing, motor mounting means mounting said motor housing for rotation relative to said chassis, means for connecting said motor output shaft to a rotatable component of a device to be tested, whereby energization of said motor will cause said output shaft to rotate and apply a torque to said rotatable componen...

The invention relates to a flexible, resilient capacitive sensor suitable for large-scale manufacturing. The sensor comprises a dielectric, an electrically conductive detector and trace layer on the first side of the dielectric layer comprising a detector and trace, an electrically conductive reference layer on a second side of the dielectric layer, and a capacitance meter electrically connected to the trace and to the conductive reference layer to detect changes in capacitance upon interaction ...

A printer including a print unit, a supply unit for holding a web of receiving material wound into a roll, a system for unwinding the web and transporting it for printing to the print unit, which supply unit is adapted to carry an elongate member on which the roll is fixed, substantially concentrically, the elongated member being provided at its peripheral edge with a pattern of sensorially perceptible discrete transitions, which pattern is substantially symmetrical with respect to a reference p...

A measuring arrangement in a roller bearing, which determines the direction of displacement of a displaceable bearing component in relation to a stationary bearing component. Four pressure-dependent resistors (R1, R2, R3, R4) of a bridge circuit are arranged successively in a line, in a measuring area on a bearing component and in a parallel manner in relation to the direction of displacement of the rolling body or the displaceable rolling component. The distance (R1-R2) is exactly the same as t...

An image generating apparatus capable of rotating a pressing member pressing a print head against a platen roller at a large rotation angle with a cam is obtained. This thermal transfer printer (image generating apparatus) comprises a drive cam for driving the pressing member. This drive cam includes a cardioid cam engaging with a cam pin provided on the pressing member and a protrusion, constituted of a first protrusion and a second protrusion, for restraining the cam pin from moving by force o...

The image forming apparatus includes a fixing device for heat fixing a toner image on a recording material, a discharge device for discharging the recording material on which the toner image is fixed by the fixing device; a blowing device for blowing air onto a lower surface of the recording material discharged by the discharge device; and a control device for controlling an amount of air blow from the blowing device in accordance with a position of the recording material discharged by the disch...

A projectile impact energy and location measurement system is taught employing a target apparatus having an impact plate of a solid durable substance such as steel or titanium. Disposed over the plate is a layer of elastoluminescent material composed of zinc sulfide and manganese embedded in an elastomeric composite. This luminescent material is designed to emit light or exhibit luminescence when elastically strained, for example when a projectile strikes the material. Optical photosensitive sen...

It is intended to provide a tape producing apparatus capable of printing on an appropriate printing medium with high quality based on data directly read from marks which are continuously printed on a release paper to show a type of a printing medium, with non-contact tape type identification devices. The tape producing apparatus comprises non-contact tape type discrimination sensors. Each label tape includes the adhesive and the release paper for protecting the adhesive. The release paper is pro...

A device is provided by which the stiffness coefficient of a flexure, in either a pitch or roll direction, can be measured while a slider is mounted thereon and while the flexure and slider are in a loaded condition as might be obtained during normal operational conditions of a HGA in a HDA. There are two methods of making the measurement, a static method in which the slider is loaded by an external weight called a pendulum and the angular displacement of the slider is measured, and a dynamical ...

Various embodiments of a printer including an actuation member are disclosed.
