A pressure-measuring glow plug for a diesel engine with a plug body (3, 4) for insertion into a cylinder of the diesel engine, a heating rod (1) which is arranged in the plug body (3, 4), and a pressure sensor, which is arranged under an initial tension between the heating rod (1) and the plug body (3, 4), in such a way that the pressure sensor (7) is acted upon by the pressure prevailing in the combustion chamber of the cylinder. The heating rod (1) transmits the pressure in the combustion chamber of the cylinder to the pressure sensor (7) and is arranged so as to be displaceable in a sliding manner in the axial direction relative to the plug body (3, 4). A seal in the form of a bellows-shaped component (2) is provided between the heating rod (1) and the plug body (3, 4).

A plant cultivation apparatus is provided, which can implement automatic spraying on leaf surfaces at any time and any number of times to improve production efficiency while preventing a facility equipped with the apparatus from having complex configuration and causing adverse effects on constituent parts. The apparatus includes a plurality of cultivation shelves 121 that store cultivation trays 110, transport means 130 for transferring the cultivation trays 110, and spraying means 140 for spraying a spray liquid on leaf surfaces of the plants. The spraying means 140 is arranged on a transfer path or at a transfer destination of each of the cultivation trays 110, and includes a separator 141 that forms a partitioned-off space, and a spray nozzle 143 that sprays the spray liquid toward interior of the space.

Improved layouts of binary and ternary content addressable memory cells (BCAM and TCAM) are shown. A content addressable memory cell layout has a plurality of P+ diffusion areas and a plurality of N+ diffusion areas that do not enclose isolation regions and on which shallow trench isolation stress can exert minimal influence on the drive current of the memories. Further, all transistors in the content addressable memory cell layout are oriented in the same direction to avoid unintended variations in electrical performance. The CAM layouts are “process friendly” to accommodate requirements of advanced process technologies such as the 90 nm process.

The assembly also comprising an attenuated total reflection (ATR) coupler (11) disposed adjacent to the second thin film metal electrode (3).

An incubator for newborn and premature patients includes an air delivery unit with an electric motor and heating and humidifying devices, a control unit including sensing devices to measure air temperature and humidity and a control panel integrally mounted to the incubator. Sensitive electrical components, such as the electric motor and control unit, are shielded from the magnetic field of the imaging equipment so that the incubator, with its patient, can be placed inside the imaging equipment and remain fully functional. Shielding for the electric motor is constructed of soft magnetic material and arranged to leave a dielectric gap between the shield and the motor.

A method and system for downlink channelization code allocation or assignment in a Universal Mobile Telecommunication System (UMTS) are presented. The method and system generate an optimal channelization or Orthogonal Variable Spreading Factor Orthogonal Variable Spreading Factor (OVSF) code to be assigned to a new channel through a route having the minimum influence while maintaining the existing or assigned OVSF codes. The inventive method and system leave reserved codes by managing generation and release of the OVSF codes. This prevents situations where the new channel cannot be assigned an OVSF code due to a lack of OVSF codes, even though there is enough available power and enough available channels.

The quartz crystal device includes a container body having: a recess; a pair of holding terminals formed on an inner bottom surface of the recess; and a crystal blank, both principal surfaces of which are provided with excitation electrodes with lead-out electrodes extending from the pair of excitation electrodes toward both sides of one end of the crystal blank. Both sides of one end of the crystal blank are fixed to the holding terminals using a conductive adhesive. Pillow members are provided on the inner bottom surface of the recess at positions corresponding to corners on both sides of the other end of the crystal blank, and the two pillow members are independent of each other. Alternatively, each holding terminal includes a first region formed near the facing holding terminal and a second region having a greater thickness than the first region formed far from the facing holding terminal.

The invention relates to a method for determining the actual oxygen load of a 3-path catalyst of a lambda-controlled internal combustion engine, whereby a value for the actual oxygen load is calculated from the signal of a pre-catalyst lambda probe and the measured air mass flow rate by integration over time, whereby the post-catalyst lambda probe is initialized when the signal is interrupted.

A batteryless tire inflation pressure detecting apparatus includes, on the body of a vehicle, antennas and a transmitter transmitting radio waves through the antennas. The apparatus also includes, on each wheel of the vehicle, a pressure sensor sensing the pressure of a tire, a transceiver, and a charging unit powering the pressure sensor and the transceiver. The charging unit is charged with electric power induced by a corresponding one of the radio waves received by the transceiver. The apparatus further includes, on the body of the vehicle, a receiver receiving pressure signals transmitted by the transceivers, a pressure determiner determining the pressures of the tires based on the pressure signals, and a controller. To minimize influence of the radio waves on neighboring devices, the controller controls the transmitter so that least two of the radio waves are transmitted at different times, or at the same with a phase difference therebetween.

An NMR resonator for receiving RF signals at desired resonance frequencies from a measuring sample in a volume under investigation disposed about a coordinate origin (x,y,z=0), with a means for producing a homogeneous magnetic field B.sub.0 in the direction of a z axis, wherein superconducting conductor structures are disposed between z=-.vertline.z.sub.1.vertline. and z=+.vertline.z.sub.2.vertline. on a surface which is translation-invariant (=z-invariant) in the z direction at a radial separation from the measuring sample, is characterized in that a compensation arrangement is additionally provided on the z-invariant surface, which extends to values of at least +.vertline.z.sub.2.vertline.+0.5.vertline.r.vertline.>z> -.vertline.z.sub.1.vertline.-0.5.vertline.r.vertline., wherein .vertline.r.vertline. is the minimum separation between the measuring sample and the compensation arrangement, wherein the compensation arrangement comprises further superconducting conductor structures which are RF-decoupled from the RF resonator, with the conductor structures of the compensation arrangement and of the RF resonator being composed of individual surface sections ("Z-structures") which comprise superconducting structures and are disposed in the z-invariant surface to each extend along the entire length in the z direction of the conductor structures of the compensation arrangement and of the RF resonator, those superconducting structures being disposed such that decomposition of the surface of the Z structures into a plurality of small equally sized surface elements and application of a homogeneous test magnetic field along the surface normal of each surface element for all surface elements which differ only with respect to their z position, induces a magnetic dipole moment of the same strength. In this manner, the disturbing influence caused by magnetization of the superconductor is very well compensated for.

An angular velocity sensor device includes a switch (S1) for selecting a first or second driving signal mutually opposite in phase applied to driving electrodes (D1, D2) to oscillate a weight part (8) in a first direction. An adding circuit (29) adjusts the amplitude of the driving signal selected and adds it to a monitor signal reflecting the oscillating state of the weight part (8). A noise signal component appearing in the output signal of the adding circuit (29) is adjusted to a minimum and the output signal is supplied as a feedback signal to a self-oscillating circuit (27) for reducing the noise signal influence on the oscillating drive of the weight part.
