Patent CA-2034075-A1 (CA)
Inventor: GODINHO NORMAN
IPC: H01L23/532
Filed: 1991-01-11
Abstract: An MOS transistor for use in an integrated circuit, particularly CMOS integrated circuits, is fabricated with a self-aligning contact and interconnect structure which allows for higher packing density.     Self-aligning source and drain contacts overlap the gate but are prevented from short circuiting to the gate by oxide insulation between the source/drain contacts and the gate, and a layer of silicon nitride above the gate. Contacts to the gate are made on top of the gate over the active region of the transistor because the source and drain regions are protected by a hardened layer of photoresist during etching of insulation to expose the gate contact. Source, drain and gate contacts are protected by a layer of titanium silicide so that interconnects are not required to completely cover these areas.  Low resistance interconnects are formed of titanium silicide encapulated by a thin film of titanium nitride.

Title: Group control for lifts with immediate allocation of target calls in dependence on the call entry location on a storey
Inventor: SCHRODER JORIS
IPC: B66B1/20
Filed: 1991-01-18
Abstract: Summary By this group control, the cages of a lift group can be so selected for boarding passengers that the boarding passengers arrive at the shaft door of the selected lift earlier than the selected cage, whereby unnecessarily long stops are avoided. For this purpose, a store (15) in which the times needed by a passenger on a storey for the paths between the respectively actuated call-registering and indicating equipment and the shaft doors of the lift are stored, is provided for each lift. A comparator (16) connected with the store (15) compares the time associated with the actuated call-registering and indicating equipment with the travelling time of the cage to the call input storey. If the travelling time is less than the time needed by the passenger to get to the shaft door concerned, a switching equipment (17) connected to the output of the comparator (16) becomes effective in such a manner that the lift concerned is excluded from the call allocation procedure.

Abstract: PCT No. PCT/CH90/00266 Sec. 371 Date Jul. 23, 1991 Sec. 102(e) Date Jul. 23, 1991 PCT Filed Nov. 21, 1990 PCT Pub. No. WO91/08477 PCT Pub. Date Jun. 13, 1991.The apparatus of the invention has two heads each of which has three sensors for measuring the propagation speed of ultrasonic waves, the degree of moisture, and the temperature in a test material, in conjunction with a module having a microprocessor and memories. The microprocessor calculates the measured propagation speed of the ultrasonic waves. This speed is normed with respect to a set temperature (e.g., 20 DEG  C.) and a set value (e.g., 15%) of the degree of moisture. From these measurements, the microprocessor searches for the class of standardized mechanical properties in which the material falls. The microprocessor finds the class in which the value of the normed propagation speed falls in a table of values contained in one of the memories. The apparatus thereby enables the determination of the class of the material automatically and non-destructively.
