A control apparatus for an electrically controlled injection pump of a Diesel engine comprises a main controller for controlling valve opening durations of an injection quantity control solenoid valve and an injection timing control solenoid valve provided for the injection pump so that a desired quantity of fuel is supplied to the engine in an optimal injection timing and a sub-controller for con...

A nuclear magnetic resonance apparatus for registering the nuclear magnetic resonance condition of atomic nuclei distributed in a body including first magnetic field generating means for generating a homogeneous static magnetic field having a thin beam shape for application to a selected portion of the body, second magnetic field generating means for simultaneously generating a gradient magnetic f...

By means of a conveying surface having depressions arranged in a pattern, a plastic is coated onto a heated substrate (2) by the intaglio process by means of a device for applying the synthetic resin powder onto the conveying surface which has a temperature at which the flowability of the powder is still preserved, so that it is prevented from adhering to the conveying surface. A heated substrate ...

Apparatus is disclosed herein for non-invasively monitoring arterial waveforms, such as the waveform produced by blood flow through the brachial artery in a human subject. The invention includes a unique transducer which senses both a pressure wave proportional to blood flow in the artery and an acoustical signal proportional to the turbulence created by blood flow through a partially occluded art...

A device for dispensing tablets, pills and the like includes an enclosure containing a first cavity to store a plurality of tablets, a second cavity disposed adjacent the first cavity and a second cavity including a dispensing wheel including slots to convey a predetermined quantity of tablets or pills to a discharge opening, a control knob placed adjacent the dispensing wheel for moving the dispe...

A transversely pleated, longitudinally heat-shrinkable tape is made from a heat-shrinkable polymeric film. One side of the tape may be adhesive-coated, and the other side may be coated with a thermochromic paint. The tape is wrapped around a substrate, and is particularly adapted, by reason of the pleats, to be wrapped around a substrate of non-uniform cross-section, e.g. a splice in a telephone c...

A static low tire pressure detection system for detecting the presence of a low tire mounted on a structural member of an aircraft, such as a bogie beam or nose axle, includes a pair of inclinometers mounted on the structural member and adapted to sense the bend therein. The signals from the inclinometers are stored in a memory once the aircraft is at rest on the ground to provide reference signal...

PURPOSE:To reduce the number of steps of and the cost of a semiconductor device by forming a solder layer which has a lower layer of lead and an upper layer of tin on the surface of the lead part which is projected from a resin package of a lead frame before mounting an element. CONSTITUTION:A silver plating film 6 is covered on an element mount 4 of a lead frame having a lead 1, a frame piece 2, ...

Electronic theft prevention apparatus including a decoder integrally formed with a vehicle component and selectively enabling the operation thereof, an encoder accessible to a vehicle operator for providing coded instructions to the decoder to enable operation of the vehicle component, and data coupling apparatus for interconnecting the decoder and the encoder to permit data transfer therebetween.

For the stable immobilization of the spine an implant is used in the form of a plate (1) of strip or sheet metal which has wedge-shaped cut-outs (2) on the two ends of the plate (1) which are arranged symmetrically towards the centre relative to the longitudinal axis and terminate in a rounding-off (5). The wedge-shaped cut-outs (2) form legs (3) having teeth (4) with rounded feet and sharp points...
