Patent EP-0227842-A1 (EP)
Inventor: ARAMAKI HITOSHI
IPC: G05B19/408
Filed: 1986-07-01
Abstract: A digitizing method which controls the movement of at least one axis (X- or Y-axis) by the numerical control based upon the passage data, which controls the movement of another axis (Z-axis) by the profile control, and which monitors the current positions of the axes in order to obtain three-dimensional data on an object. A numerical controller (101) performs numerical control based on NC data supplied from an NC tape (106) to move a tracer head (105) in the X-and Y-directions. A profile controller (102) performs the control relying upon displacement components (εx, εY, εz) of the axes generated by the tracer head, to produce a speed instruction V z  of the Z-axis, and to move the tracer head in the direction of Z-axis. The numerical controller (101) counts the number of pulses (F z ) generated every after a motor (M z ) that drives the profile control axis (Z-axis) has made rotation of a predetermined angle, and obtains the current position of the profile control axis. The numerical controller further obtains an instruction position of the numerical control axes (X-, Y-axes) using the passage data, and subtracts servo delay amounts (E x , Ey) which are the contents of error registers (ER . , ERy) from the instruction position, in order to obtain a current position expressed by a mechanical position. Thereafter, the current positions of the axes represented by mechanical positions are stored in a memory (101b) every after a predetermined period of time.

Abstract: The contact elements for the connection of individual wires guided in an ordered manner side by side project with a box-shaped U-profile into wire channels on the wire connection side of the connector. Side walls of the U-profile aligned at right angles to the channels are each provided with a contacting slot. The contact elements are supported on walls bounding the channels on the sides, in the region of the wire channels, by means of a lateral wall of the U-profile and angled sections of the side walls. A cover which can be latched onto the connecting side projects into the channels with ribs. This arrangement produces a wire connection which can even withstand rough operating conditions. <IMAGE>
Patent EP-0306553-A1 (EP)
Inventor: SEEGER RICHARD E
IPC: H05K1/03
Filed: 1987-09-11
Abstract: This invention describes a platable plastic material that uses a phosphide compound as a filler at levels of 5 to 40 weight percent. The phosphide filler used in this way has good dielectric properties and is non conductive, but the phosphide provides coupling sites for a conductive plating to initiate and to bond to the filler and thus to the plastic. Surface treatment of the plastic may be needed to expose the particles but this invention removes requirements for catalytic treatment with noble metal chlorides and relies on bonding mechanisms other than the mechanical grip on a rough surface.

Title: Nuclear magnetic resonance apparatus having a detection coil including a decoupling circuit with p-i-n diodes
Inventor: VAN HEELSBERGEN TEUNIS ROBERT
IPC: G01R33/38
Filed: 1987-12-15
Abstract: The n.m.r appts. has a magnetic system to generate a static homogenic main magnetic field and another system to generate graded fields. A transmitting coil generates a spatially homogenic h.f alternating magnetic field in an investigation area. A detector coil (L) registers the resonance signals produced in the investigated object. These signals are then processed. At least one PIN diode (P2) is in series in the resonance circuit (L,C1,C2,C3). At least one other is in series in the line leading to the processing circuitry. A PIN diode (P6) ensures that no current can flow in the lead to the detector after the resonance circuit is switched off. Further PIN diodes (P4,P5) ensure that no h.f current can flow in the leads to the tuning capacitor (DCT) and the equalising capacitor (DCM).

Inventor: SCHOLLER KARL RONALD
IPC: B60L5/18
Filed: 1988-02-29
Abstract: System for transmitting signals in the form of state variables over lines subjected to severe temperature variations, which prevents interference to the signal transmission as a result of the temperature variations. This is achieved by the fact that there are two measured value transducers at the input of the signal transmission system which influence the variables that transmit the signal; two measured value sensors are connected to the output side of these transducers via adjacent transmission lines and variations of opposite sense in the variables in the measured value transducers are generated as signals and the differences in the variables are detected as signals in the measured value sensors. This system is used particularly for determining the application pressure of the current collectors of electric traction units by measurement of a pressure-dependent deformation of the current collector frame by means of hydraulic or pneumatic pressure transducers. <IMAGE>

Abstract: A process of forming a multi-level semiconductor metalli­zation structure from a single deposit layer of metal. The process provides the versatility of allowing stud-up, stud-down, thick and thin metallization line structures to be formed from the single layer of metal. The thick metalli­zation line structures are low resistance lines, and the thin metallization line structures are low capacitance lines. The separation of the thin metallization lines from the semiconductor substrate can be controlled to further decrease capacitive effects.
