Patent CA-2074367-A1 (CA)
Title: Proportional pressure control valve
Inventor: PATEL KISHOR J
IPC: B60G17/08
Filed: 1990-12-24
Abstract: A proportional pressure control valve is disclosed which may be used for uni-directional or bi-directional fluid flow. An electromagnetic driver (35, 251, 360) mounted in a driver cavity (36, 353) of a housing produces a magnetic flux path in response to a variable input current. The magnitude of the flux path is substantially proportional to the input current. The flux path passes through an armature (40, 276) which is movable within the driver cavity. The armature is connected to a metering spool (64, 209, 260) so that the two move in unison. The metering spool is movable within a main bore between a sealing position and an infinite number of open positions. The position of the metering spool determines the magnitude of fluid communication between pressure ports. A  feedback section (85, 98) of the housing establishes a pressure feedback force which impacts on the position of the metering spool and the armature. The valve may also include a spring (272) for biasing the metering spool to a fail-safe position within the housing. The proportional pressure control valve can be incorporated into a damper of a vehicle suspension system where the input current is governed by an electronic control unit (56) of the vehicle.  The electronic control unit (56) may be responsive, in part, to the position of the suspension system through the use of a position feedback sensor (101).

Title: Linear film scanner operable at different line rates
Inventor: LEES ROGER T
IPC: H04N1/04
Filed: 1992-06-08
Abstract: A film scanner operable according to dual line standards includes red, green, and blue linear array sensors (36r, 36g, 36b) separated by a line spacing that constitutes substantially integral first and second multiples of the line spacings of the respective line standards. More particularly, in 1125 and 1250 line television standards, the linear arrays are spaced such that the distance is substantially equivalent to 9 lines of the 1125 line standard and 10 lines of the 1250 line standard. The output signal from each linear array is registered to the same line for each standard by inserting separable sets of line delays (52a, 52b, 53a, 53b) into the signal paths from two of the linear arrays. The separable delays correspond to the first and second multiples of the respective standards. By enabling a switch (54a, 54b) to switch between the respective sets of delays, an output signal is developped for a selected line standard.

IPC: H03L7/22
Filed: 1993-03-31
Abstract: In a phase locked loop frequency synthesizer having multiple feedback loops, a reference phase signal is developed into two signals having a frequency twice as high as the reference frequency and the phase difference of the two signals is a half wavelength.  The output frequency produced by a voltage-controlled oscillator is divided by two frequency dividers in accordance with predetermined frequency division factors.  Each of the frequency-divided signals and each of the developed signals are subjected to phase comparison in pairs.  A voltage signal corresponding to the phase differences is fed through a low-pass filter and supplied to the voltage-controlled oscillator.

Abstract: A linear and symmetrical gigaohm resistive load structure for an integrated circuit is implemented using a thin film accumulation mode MOSFET configured as a split gate symmetrically off device.  Preferably, the resistive load structure comprises two thin film accumulation mode field effect transistors connected in series with a common node and separate gate electrodes.  The thin film devices are provided with undoped or lightly doped polysilicon channel regions to provide a desired gigaohm resistance value.  By connecting each of the two gate electrodes to the respective source terminals, a two terminal gigaohm resistor structure is produced in which one of the devices is always in the high impedance OFF state regardless of the terminal voltages.  The split gate structure allows the integration of the device with minimal metallization interconnect and only two terminals.     (i)

Abstract: ABSTRACT            DRILL PIPE       In order to achieve improved flow properties for a flushing medium charged with rock particles freed during the drilling phase, an injection drilling anchor is proposed whose anchor rods (2), coupling members (3), injection valves (15), an intermediate member (9) containing a non-return valve, as well as drill head (1) are designed such that these components are connected one to the other below one another always by screw fittings, so that in the assembled state one has a fully homogeneous structure from the drill head (1) upwards.  The drill head is characterised by an external thread extending uniformly over the full length and consequently has a uniform diameter, so that after drilling has taken place, starting from the mouth of the borehole, a spacer can be pushed within the borehole along the full length of the borehole over the anchor rods (2) to any desired point.  The anchor rods (2) are provided over their full length with a uniform internal threading, so that a cutting to a particular length does not hinder their utility for use in the framework of the injection drilling anchor (1).  The coupling  members,  the  injection  valves  (15), intermediate member (9) and the drill head (1) for this purpose comprise tubular cylinders (20, 21; 10; 6) which correspond in terms of their internal and external threading with the anchor rods (2) and which each have a stop function for the positional screwing together of the parts.
