Patent EP-0367344-A2 (EP)
Inventor: KUNZ DIETMAR WILHELM DR
IPC: G01R33/483
Filed: 1989-10-30
Abstract: The invention relates to a method in which for the purpose of suppressing the doublet structure of compounds containing at least one CH group in carbon and hydrogen a first magnetic high-frequency field with the Larmor frequency of carbon is generated, whereupon a second magnetic high-frequency field with the Larmor frequency of hydrogen in the CH group concerned has an effect on the region of investigation, and the generated nuclear resonance signal is measured, and an arrangement for carrying out the method. In this process, decoupling can be achieved in conjunction with reduced high-frequency loading when at a prescribed time dt after the end of the excitation of the carbon a magnetic high-frequency pulse of duration T and amplitude Bp is generated, as a first step, directly thereafter the amplitude of the HF field is reduced to a value Bc and during this time the nuclear resonance signal is measured, and the parameters dt, Bc and Bp are selected such that the modulation of the nuclear resonance, occasioned by the J coupling signal, precisely vanishes. …<IMAGE>…

Abstract: In an integrated circuit chip (10) utilizing CMOS technol­ogy, an embedded data bus (11) is driven by embedded three state drivers (12-15), and the bus is in turn connected to provide a drive signal to embedded receivers and similar logic devices. An embedded threshold detector (19) is provided to detect the occurrence of any invalid data signal (i.e. a non-"0" or a non-"1" signal level) on the data bus. The threshold detector's output signal is connected to off chip terminal means, to thereby enable off chip monitoring of the bus signal. The threshold detector's output signal is also ANDed with the bus sig­nal, to thereby prevent the application of a potentially destructive invalid bus signal to the receivers and the like. Terminator circuit means provides a known invalid signal state on the bus when the bus is in its high imped­ance state due to all of the three state drivers being disabled.

Abstract: The invention relates to an apparatus for the floatable guiding of webs of material by air blown against the web. The apparatus comprises blowing boxes 2-6 disposed offset in relation to one another above and below the web 1 of material. Each blowing box 2-6 has two opposite rows of blowing apertures 21 whose blowing direction encloses an acute angle a2 with a deflecting surface 25, 26 which adjoins the edge of the blowing aperture 21 remote from the web 1 of material. The deflecting surface 25 also encloses an acute angle a3 with the web 1 of material. The two acute angles a2, a3 are so selected that the air blown out of the blowing apertures 21 is guided away the deflecting surfaces 25 and against the web 1 of material, where it spreads out in the form of a source flow 30. In this way both a strong air cushion supporting the web 1 of the material is obtained and also a high heat transfer at the web 1 of material and a clearly-defined flow of the blown air from the air cushion.

Abstract: An electrical connector has several rows of contacts connected to two rows of leads that engage terminals on a circuit board assembly, which enables a large number of contacts to be located in a connector of moderate cost. A connector insert comprises a wafer device and multiple leads, the leads having front lead portions connected to multiple rows of contacts on the wafer device, middle lead portions moulded into the wafer device, and rearward lead portions lying in two parallel rows for contacting terminals on opposite sides of the circuit board assembly. Each wafer device includes two substantially identical wafers, to allow moulding of a single row of leads at a time into a wafer. Each wafer has forwardly projecting towers that each lie around the front portion of a lead, and each contact has a periphery captured by a tower portion and a hole that receives a lead front portion. The contacts are arranged in columns on the wafer device, with at least four contacts in each column, and some of the lead middle portions extend both laterally and longitudinally to provide a small spacing or pitch of the lead rear portions. The insert has leaf springs at opposite sides for centering the insert in the connector housing while allowing the insert to "float" within the housing.

Abstract: A phase locked loop provides a programmable frequency output signal. A phase detector (18) detects a phase difference between a reference frequency (F REF ) divided by a first number (R), and a frequency of the output signal (FR OUT ) divided by a second number (N). First and second counters (14,16) receive the first and the second input numbers to divide a respective frequency. Whenever an input number is loaded, a load signal (JAM LOAD) resets the phase detector and causes each counter to be loaded, which reduces the lock time of the loop.
