Title: Device for automatically closing a power roof of a vehicle
Inventor: MEMMOLA SERAFINO
IPC: B60J7/057
Filed: 1988-06-30
Granted: 1991-07-23
Abstract: DEVICE FOR AUTOMATICALLY CLOSING A POWER ROOF               OF A VEHICLE                 ABSTRACT OF THE DISCLOSURE           A motor vehicle has a power roof which can either rotate between a first open position and a closed position or translate between a second open position and the closed position.  An electric motor for opening and closing the roof operates from a battery of the vehicle and is connected to the battery by a circuit which can be closed by either of two switches.  When one of these switches is closed while the roof is in its closed position, the motor opens the roof by rotation.  Closing of this same switch when the roof is translated from the closed position causes the motor to translate the roof towards the closed position.  When the second switch is closed while the roof is in its closed position, the motor opens the roof by translation.  On the other hand, closing of the second switch when the roof is rotated from its closed position causes the motor to rotate the roof towards the closed position.  The vehicle is equipped with a security system which also operates from the battery and, upon activation, sends a signal to the circuit connecting the motor to the battery.  In response to this signal, the circuit issues a sequence of four pulses.  The first pulse is short and briefly actuates one of the switches.  The second pulse, which is at least as long as the first pulse but can be considerably longer, actuates the other switch.  The third pulse, which is again short, briefly actuates the latter switch once more. The fourth and final pulse, which is at least as long as the third pulse but can be considerably longer, again actuates the switch previously actuated by the first pulse.  This sequence of pulses causes the roof to close completely regardless of the position of the roof at the time the security system is activated.

Patent CA-1291539-C (CA)
Title: Quotient phase-shift processor for digital phase-locked-loops
Inventor: GUINEA JESUS
IPC: H03L7/06
Filed: 1988-10-13
Granted: 1991-10-29
Abstract: Abstract A quotient phase-shift processor is provided which includes novel techniques for realizing phase corrections of a digital phase-locked-loop.  A binary phase-detector of the "early-late" type is combined with range-phase-detector circuitry to generate a variable lock acquisition speed.  Phase measure and speed control are performed by incremental manipulation which feeds a novel "quotient" processor.  The quotient processor integrates the incremental phase errors and performs phase corrections in a nonperiodic fashion, resulting in lower effective proportional loop gain than that provided in standard phase-locked-loops. Wide capture-range and low jitter are obtained by dynamically varying a loop time constant.  Pattern dependent noise is reduced by a novel gating technique. High crystal-frequency requirements are reduced, extending the spectral application of digital phase-locked-loops.

Title: Semiconductor device with low defect density oxide
Inventor: DOKLAN RAYMOND H
IPC: H01L21/316
Filed: 1988-12-21
Granted: 1991-05-14
Abstract: Semiconductor Device with Low Defect Density Oxide Abstract Low defect density oxides suitable for use as thin gate oxides or in charge storage capacitors are described. First and second dielectric layers are formed on a substrate with misaligned defect structures. A third layer (an oxide) is then grown by diffusing an oxidizing species through the first and second layers to the substrate. The species reacts with the substrate. The low defect density results from the misaligned defect structure of the first and second layers. In one embodiment, the first and second layers are grown and deposited oxides, respectively. The third layer is grown by diffusing oxygen through the first two layers, where the interface between the first and second layers acts as a sink trapping defects. The oxide silicon interface has desirable characteristics (essentially planar and stress-free) because the oxide grows in near equilibrium conditions.

Title: Swather attachment for bi-directional tractor
Inventor: HONEY GREGORY J
IPC: A01D75/00
Filed: 1989-07-10
Granted: 1993-05-25
Abstract: ABSTRACT    A mounting structure for attaching an elongated swather head to a tractor of the bi-directional type, the structure mounting the head in front of the tractor in a swathing direction of travel and accommodating swinging movement of the head to a trailing transport mode behind the tractor when traveling in a direction opposite to the swathing direction.  The mounting structure is carried by the tractor which, in the operational mode of the swather, is disposed to one side of the centre-line of the swather head.  The mounting structure includes members for securement to the tractor and an elongated support member projecting transversely across the front of the tractor to the side of the tractor opposite to the centre-line of the swather head. The head has a rear frame member which extends parallel to the head behind an intermediate portion thereof and is carried at one end by a hinge connection to the support member at the side of the tractor opposite to the centre-line of the swather head.  The hinge connection permits pivoting of the frame member of the swather head about a substantially vertical axis for accommodating the swinging movement of the swather head to a trailing transport mode.  A lock is associated with the frame and support members for selectively holding the frame member against the swinging  movement when used in the swathing operation.  The mounting structure allows use of a swather head on a bi-directional tractor which may be of the centre articulated type, so that when moving in one direction, normal swathing is carried out, but the swather can assume a trailing travel mode when the tractor is driven in the opposite direction, thus allowing the machine to occupy considerably less width. Also because the tractor is not centrally disposed behind the swather head, the swather can be designed to lay a windrow at a distance from the end of the swather and yet in a position which will avoid being disturbed by the tractor.

Abstract: CLEANING DEVICE WITH SUCTION NOZZLE    AND LIQUID AND GAS SEPARATOR                   ABSTRACT          A machine for cleaning surfaces such as carpets, floors, and the like, has a frame (30) on which is mounted an upper housing (56) containing an air pump (62).  An assembly of a fresh liquid container (48) stacked on a waste liquid container (50) is removably mounted on the frame with the aide of a cam latch (54).  The air pump communicates with a housing (160) which provides pressurized air to outlets (158, 166, and 168) and suction to a suction nozzle (46) through a conduit (173) which carries waste liquid and air picked up from the carpet to a separator (58) in the housing (56).  A cleaning fluid container (64) is removably mounted in a docking port (68) in the housing (56) and aligned and locked in communication with couplings (254) in the docking port (68) by a rotatable collar (66) having a camming recess (220).  The clean liquid container (48) and the cleaning fluid container are pressurized by connections thereto from the air pump outlets (166 and 168) to provide for the delivery of fresh liquid or fresh liquid and cleaning solution mixtures of selected concentration to a spray nozzle (42) to which pressurized air is also applied from one of the pressurized air outlets (164) via a conduit (158). The delivery and concentration of the fresh liquid and/or cleaning fluid is controlled by a actuator (40) which operates a rocker arm (102) for constricting tubing associated with a coupling (90, 126) in which the pressurized cleaning fluid and fresh liquid are combined.  The suction nozzle has a passage (274, 276) for facilitating flow of air and waste water and making such flow visible.  The separator (58) includes a conical shroud (172) which facilitates separation of waste liquid from the air picked up from the surface being cleaned.  The assembly of fresh water and waste water tanks (48, 50) has a conduit (181) leading from the bottom of the separator housing (160) through the fresh liquid tank into the waste liquid tank.  A keyway (184) on the tanks facilitates their alignment with a member on the frame (30) containing the conduits (159 and 173) for the pressurized air to the spray nozzle and the air and waste liquid from the suction nozzle and which provides a key for alignment of the assembly of containers (48 and 50) on the frame (30).  The cleaner may be rolled on wheels (32) by a handle (36) connected to the frame (30).
