Abstract: A method for fabricating a low resistivity polymetal silicide conductor/gate comprising, the steps of forming a polysilicon (66) over a gate oxide (64) followed by protection of the polysilicon (66) with a sacrificial material (68), is disclosed. Gate sidewalls (70) are created to protect the sides of the polysilicon (66) and the sacrificial material (68), followed by stripped the sacrificial material (68) to expose the top surface of the polysilicon (66). Next, a diffusion barrier (76) is deposited over the exposed polysilicon (66) and a metal layer (78) is selectively grown on the diffusion barrier (76) to form a gate contact and conductor. Finally, a dielectric layer (80) is deposited over the selectively grown metal layer (78), the sidewalls (70) and the gate oxide (64).

Abstract: The casing of a passive proximity transceiver includes a protrusion which extends from the main body of the casing to prevent metal objects from touching the main body, where they would otherwise be close enough to interfere with reception of signals transmitted between the passive proximity transceiver and another electronic device. The casing may be arranged to be mounted on a key ring, with the protrusion being in the form of a collar extending around the main body.

Abstract: A low frequency vibration sensor includes a permanent magnet, a sensor body, a steel spheroid, and a piezoelectric element. The sensor body has a pillar shape and is made of plastic material having a transverse separator section in a middle portion to divide the sensor body in an upper and a lower spaces. A depressed slot is formed around the upper space for disposing the magnet, while the lower space is made larger than the steel spheroid so as to accommodate it therein movably and also put under the influence of an attractive force of the magnet above. A piezoelectric element is set in along a grooved rail provided around the bottom edge of the sensor body to thereby form a closed space. The steel spheroid is movable to swing in the space such that its motion is conducted to the piezoelectric element to induce a corresponding low frequency electric signal between two electrodes of the piezoelectric element to thereby detect the vibration caused by an external force.

Abstract: A metal-poly stack gate structure and associated method for forming a conductive barrier layer between W and poly in the metal-gate stack gate structure. The process includes the steps of depositing doped silicon on a substrate; forming nitride on the deposited silicon; depositing a metal on the nitride to form a metal/nitride/deposited silicon stack; and thermally treating the stack to transform the nitride into a conductive barrier layer between the metal and the deposited silicon. The thermal treatment transforms the nitride layer (SiN.sub.x or SiN.sub.x O.sub.y) into a conductive barrier (WSi.sub.x N.sub.y or WSi.sub.x N.sub.y O.sub.z) to form a W/barrier/poly stack gate structure. The barrier layer blocks reaction between W and Si, enhances sheet resistance, enhances adhesion between the W and the poly, and is stable at high temperatures.

Abstract: A vehicle security device of the present invention comprising of a remote control, a receiver/decoder section, a CPU, and an amplifying section. It has been designed to arm in two ways--by remote control, and by timer. By pressing the button #1 of the remote control, the vehicle security device will be armed. The vehicle security device has two separate counters--the 10 minute counter, and the 30 second counter. No matter doors are close or open, the 10 minute counter will start counting after turning off ignition and will continue counting even if a door is opened while the 30 second counter will only start counting if any door of the car is opened and closed (provided all the remaining doors are close) but will stop counting if any door of the car is opened. The vehicle security device will arm itself if any of the two counters finished counting (whichever finished first). However, if the ignition is turned on during countdown, the car can be started and both counters will stop counting.

Abstract: A security system uses an ordinary switch, which may be an existing switch such as a parking light switch, to enter digits of a security code, with the beginning of a digit being indicated by turning on the ignition switch and the end of a digit being signified by turning off the ignition switch. Entry of the security code can be used to perform an emergency system disarm when the remote control transmitter is lost, to change the security code when the transmitter is in the possession of the owner, and to teach a new transmitter.

Abstract: An anti-hijack security system which automatically protects the vehicle with anti-hijack after the ignition has been turned off for a predetermined long period of time or after the ignition has been turned off and a door has been opened and closed for a predetermined short period of time. Thus, ensuring the owner to have anti-hijack protection when he returns to his vehicle.

Abstract: The present invention relates to a bicycle speed change lever apparatus which is mounted near the handlebar of a bicycle. A lever apparatus is used for pushing a ratchet member, allowing the ratchet member to produce a positive or negative rotation, which further drives a cable-pulling member, thus allowing the cable to be tightened or relaxed by the cable-pulling member to accomplish an in or back shift. A position maintaining mechanism is also provided for effectuating the shift change, and the cable is allowed to maintain a certain amount of tension. The speed change lever apparatus eases the shifting operation and makes the in shift or back shift more precisely controlled.
