Patent IT-TO20001070-D0 (IT)
Inventor: ANTONIOLI PIERPAOLO
IPC: F02D45/00
Filed: 2000-11-14
Abstract: There is described a method of diagnosing leakage in a common-rail injection system (1) of an internal combustion engine (2) having a number of cylinders (4); the injection system (1) having a number of injectors (14), each supplying high-pressure fuel to a respective cylinder (4) of the engine (2), and a fuel supply circuit (16, 18) supplying fuel to the injectors (14). The diagnosis method includes the steps of determining the contribution (ACi) of each cylinder (4) to the angular acceleration of the engine (2); determining, for each cylinder (4), an unbalance index (ISi) indicating the unbalance of the angular acceleration contribution (ACi) of the cylinder (4) with respect to the angular acceleration contributions (ACi) of the other cylinders (4); reducing, upon detection of a fault in the injection system (1), the amount of fuel injected into each cylinder (4); and distinguishing, for each injector (14), between a jammed-open injector condition and a fault condition in the fuel supply circuit (16, 18), on the basis of the variation in the unbalance index (ISi) of the respective cylinder (4) following the fuel reduction. <IMAGE>

Granted: 1984-10-31
Abstract: A dental handpiece arrangement which has a drive transmission for transmitting the rotation from a motor to a socket receiving the tool in the head of the handpiece comprising a first drive shaft having a pair of coaxially arranged drive gears of different numbers of teeth, a second drive shaft having a gear engaging one of the pair of coaxial drive gears characterized by the second drive shaft being composed of a first drive shaft portion and a second drive portion which are interconnected by meshing gears providing a change in the gear ratio. Preferably, the two drive shaft portions of the second drive shaft are mounted in a housing with a gear at each end and the housing is adapted for being supported in the handpiece arrangement in two different positions so that in a first position, a gear at one end is engaging one of the pair of coaxial gears of the first drive shaft and in the second position the gear at the opposite end is engaging the other of the pair. Thus, by changing the position of the housing, a continuous stepping-up of the gear ratio can be obtained or by reversing the position of the housing a continuous stepping-down of the gear ratio can be obtained.

Abstract: In a method of making a fibrous thermally insulating layer of coherent structure, a quantity of fibers is treated with a binder, whereby prior to or during the treatment with the binder, fibers are formed into a quantity of particles each having a substantially rounded periphery and consisting of a number of short fibers and the particles treated with the binder are conveyed by means of a gas as conveying medium via an inlet piece 11, 13 to within a container 3, the particles being blocked by an outlet piece 8 for the container, the outlet piece 8 being formed with gas outlet apertures 10. The particles are formed by vigorously agitating a number of flakes in a vessel, each flake consisting of arbitrarily arranged short fibers, and simultaneously applying pulsating forces to at least part of the volume of flakes, so that the flakes are converted into particles having a substantially rounded periphery and having a higher density than that of the flakes.

Abstract: A method and system for navigation is disclosed comprising a plurality of transmitters, pairs of which are excited from a common frequency source, and a receiver responsive to and deployed within the wave fields created by the transmitters. The receiver is provided with its initial coordinate position and determines movement therefrom by detecting beat frequency cycles resulting from the relative movement between the receiver and the transmitters of a transmitter pair. The receiver position change is computed according to the beat frequency cycles detected. In a preferred embodiment, transmitter pairs are arranged generally perpendicularly to establish a coordinate system and transmitters of a transmitter pair radiate different frequencies that are precisely related to a common excitation frequency source. The receiver detects the transmitted signals, compensates for the precise frequency relationship employed at each transmitter pair, and compares the signals from each transmitter pair to detect beat frequency cycles which are used to compute receiver position change.

Abstract: The apparatus comprises a rear plate (5) and two covers (6, 7) and progressively makes available at the outside a length of a towel band (40) by unwinding the same from a supply roll (11), at the same time recovering an equal length of soiled towel and winding it over a second roll (12), both rolls being housed within the apparatus. The apparatus comprises towel dispensing means (55, 50, 70) and recovery or take-up means (57, 58), the latter being coupled through a kinematic chain (110, 105, 135) to the former. An energy accumulating device (150) is partially loaded at each user's pull operation and released by the trailing end of the clean towel passing by a sensing plate (181) equipped with detecting blades (184). After the passage of the trailing end, the blades (184) engage gaps provided between each two roller sections (63) forming one (170) of the dispensing rollers, thereby elastically returning a pair of parallel levers (305, 306) to a disengaged position wherein a pin (92) carried by one (306) of the levers releases the accumulator (150) that in turn, via gear wheels (155, 160, 157) causes an additional rotation of one (57) of the take-up rollers pulling the trailing portion of the soiled towel (40) within the dispenser.

Abstract: An integrated circuit having a plurality of devices on a substrate is disclosed, wherein a plurality of metallization layers, separated by a plurality of insulating layers, are used to interconnect the devices. Each metallization layer is recessed in an upper portion of a corresponding dielectric layer. A metallization layer is connected to a lower one, or, in the case of the first metallization layer, to the devices, by solid contacts extending through via windows in the lower portion of the corresponding dielectric layer.A method of manufacturing such an integrated circuit is also disclosed, whereby each layer is formed in two steps. First, the lower portion of the insulating layer is deposited, the contact pattern opened and the vias windows filled with metal to provide contacts even with the top surface of the lower portion of the insulating layer. Then, the upper portion of the insulating layer is deposited overthe lower portion, the metallization pattern opened, and the pattern filled with metal up to and even with the top surface of the upper portion of the insulating layer. The metal filling step is produced by depositing a metal layer over the corresponding portion of opened insulating layer, masking the opened regions and selectively and directionally removing the unprotected metal layer.

Abstract: An electromagnet device has a pair of electromagnets (10a, 10b) and a movable body (13, 13a, 16) movable by alternately switching the electromagnetic forces thereof. A controller (20, 21) for the device has a drive circuit (20) with switches (QL1, QL2, QR1, QR2) controlled by control means (21) which receives a command signal which initiates displacement of the body and current reference values. Comparators (CM1, CM2) compare these reference values with currents flowing throughthe coils (SR, SL) of the electromagnets. The control means (21) functions to cause the drive circuit (20) to supply current to both coils (SR, SL) of the electromagnets to maintain the movable body in an electromagnetically held state. When a first of the coils (SR) is in a state of holding the movable body the control means causes a current (IH) to be supplied to the first coil (SR) to maintain the holding state and causes a pre-energising current (IE) to be supplied to the second coil (SL). When the command signal signifies the body is to be displaced the holding current in the first coil (SR) maintaining the holding state is suddenly reduced.
