Abstract: A gradient magnetic field assembly (20) selectively causes gradient magnetic fields linearly across the examination region (12) of a magnetic resonance imaging apparatus. The gradient coil assembly includes a pair of planar y gradient coils (22a, 22b) and a pair of planar x gradient coils (24a, 24b). On each plane, the gradient coil winding includes a pair of larger, outer coil loop arrays (60, 62) and a pair of smaller inner coil loop arrays (66, 68), the smaller pair producing a first order gradient field correction to improve the accuracy of the gradient field.

Abstract: Spurious programming phenomena caused by the substrate currents of an integrated circuit are prevented by providing for a measurement of these currents, and a circuit for cancelling operation of the integrated circuit when the result of this measurement exceeds a certain threshold. Preferably the measurement of the substrate current is obtained by constructing a bipolar type transistor (T2) whose base region consists precisely of this substrate, or by constructing a field-effect type transistor (21-23) whose grid (23) and one (21) of whose active regions is connected to the earth terminal of the circuit. However, these two connections differ. One of the connections is direct, the other being a connection subject to the fluctuations in the potential of the substrate.

Abstract: The keyboard input unit consists essentially of a conductor matrix, a keyboard with input keys for coupling mutually crossing conductors, and a control and evaluation circuit (P). In order to prevent spying on an operated key, in the original state, each conductor (A-H) is connected to an ideal source. A conductor interrogation takes place, for example, by connecting a conductor (A-H) to a load-dependent source. If this conductor (A-H) does not assume the value of the load-dependent source, then this conductor (A-H) is coupled at a crossing point (1-28) to another conductor (A-H) through a pressed key. Externally, the original state is simulated. Pressed and released keys are simulated in a similar manner. <IMAGE>

Abstract: Light from a light source is linearly polarized by a polarizer (13) and is then splitted by an optical splitter/couler (14) into two, which are simultanesouly coupled, as right-handed light and left-handed light, into both ends of an optical fiber coil (16). The right-handed light and left-handed light emitted from the both ends of the optical fiber coil are coupled by the optical splitter/couler into interference light, which is extracted after passing through the polarizer and is converted into an electric signal corresponding to its intensity. The phase difference between the right-handed light and the left-handed light, corresponding to an angular rate applied to the optical fiber coil, is detected from the electric signal. In the present invention, a depolarizer (25) is inserted in series at an arbitrary position in a loop from one end of the optical splitter/couler to the other end thereof via the optical fiber coil. The difference between the difference in propagation time between perpendicularly intersecting polarized light components in the depolarizer and the difference in propagation time between perpendicularly intersecting polarized light components in the optical fiber coil is selected larger that the coherence time of light which passes through the loop.

Jedes Tabellenfeld der letzteren enthält zwei Wahrscheinlichkeitswerte, von denen ein erster die Wahrscheinlichkeit ist, dass die Abtastwerte (zo[kTb], z1[kTb]) im betreffenden Tabellenfeld liegen, wenn das erste Signal gesendet wurde, und ein zweiter die Wahrscheinlichkeit ist, dass die Abtastwerte (zo[kTb], z1[kTb]) im betreffenden Tabellenfeld liegen, wenn das zweite Signal gesendet wurde. In einem Tabellenfeld der Entscheidungstabelle wird jeweils ein erster Logikwert abgelegt, wenn der erste Wahrscheinlichkeitswert grösser als der zweite Wahrscheinlichkeitswert ist, und ein zweiter Logikwert, wenn der erste Wahrscheinlichkeitswert kleiner oder gleich dem zweiten Wahrscheinlichkeitswert ist. Das Verfahren kombiniert die Vorteile des inkohärenten Demodulationsverfahrens und des Spreizbandverfahrens. <IMAGE>

Abstract: A method for manufacturing a glass container includes the steps of (a) providing a plunger (1) coated with a ceramic coating (3) or a sprayed metal coating (2) of self-fluxing alloy or both coatings on at least one portion of a surface of the plunger and (b) forming a lubrication carbon layer on surfaces of molds including a blank mold and a neck ring by periodically injecting (14) flames of at least one kind of gaseous hydrocarbon having a carbon to hydrogen ratio more than 0.75. The coating of the plunger (1) prevents the plunger from being oxidized so that flaking of an oxidized layer which will be accompanied by generation of defects at an inside surface of a glass container does not occur. Due to the carbon layer formed through flame injection of hydrocarbons, oiling of the molds is unnecessary and generation of bubbles in the oil film does not occur. This method not only increases the impact strength of a glass container but also increases the uniformity of impact strength.
