Title: Double dc coil timing circuit
Inventor: HURLEY RICK A
IPC: H01H47/04
Filed: 1992-04-16
Abstract: Abstract of the Disclosure Control circuitry is disclosed for electrical starters, contactors and the like having a starting wind-ing and a serially coupled holding winding wherein the holding winding is shorted until the separable main con-tacts have closed which includes circuitry which obviates the need for relatively precise sensing of the position of the separable main contacts to control the holding wind-ing.  In one embodiment of the invention, the unshorting of the holding winding is delayed a predetermined number of cycles after the separable main contacts have closed to avoid the necessity of relatively accurate mechanical sensing of the position of the separable main contacts. In this embodiment a relatively less expensive field effect transistor or the like is used to short out the holding winding until the separable main contacts have closed.  This allows the use of a relatively less expen-sive limit switch with a substantially smaller DC cap-ability.  In alternate embodiments of the invention, con-trol circuits are provided which allow the limit switch normally used for sensing the position of the separable main contacts, to be eliminated altogether, thus further reducing the cost of the device as well as the labor cost involved for adjustment of the limit switch.

Filed: 1992-06-12
Abstract: "Phase-Locked Loop Having Charge Pump Driven With Preserved Energy For Instant Channel Switching"                       ABSTRACT OF THE DISCLOSURE   A frequency synthesizer comprises a voltage controlled oscillator, and a variable frequency divider for dividing the VCO frequency according to the frequency of a communication channel. The output of frequency divider is compared with a reference frequency and a phase difference of first polarity and a phase difference of second polarity are detected. A charge-control voltage is generated with a duration variable with the phase difference of first polarity and a discharge-control voltage with a duration variable with the phase difference of second polarity. First and second integrators are coupled respectively to outputs of the phase comparator for respectively smoothing waveforms of the control voltages. Energy is injected into a charge pump in response to the smoothed charge-control voltage and drained from it in response to the smoothed discharge-control voltage to produce a frequency control signal for coupling to the VCO. To achieve instant switching between adjacent channels, a differentiator is coupled across the outputs of the phase comparator for preserving part of energy to be supplied to or drained from the charge pump until sufficient energy is stored.

Title: Writable distributed non-volatile analog reference system and method for analog signal recording and playback
Inventor: SIMKO RICHARD
IPC: G11C27/02
Filed: 1991-09-23
Abstract: A writable distributed non-volatile analog reference system and method for analog signal recording and playback having application in integrated circuits which sample and directly store analog information (ANAIN). The invention is useful to facilitate the sensing of analog levels stored in nonvolatile memory cells (10) where the analog levels are played back such as to reproduce voice or music or tone information. In accordance with the method, one or more reference storage columns (11L, 11R, 12L, 12R) are included in the array (10) at each side of the storage cell array (10) and are used to store a referene signal at the same time that the adjacent storage cell stores a signal sample. On playback, the stored reference signals for the row of the array are read back and weighted relative to each other in accordance with the relative row position of the signal being taken as the difference between the signal sample read back (VARAY) and the reference signals read back (VREF) (as weighted relative to each other as per the position in the row of the signal cell). The differencing places many error sources in the common mode, thereby substantially eliminating the same from the output signal. A specific memory array organization and the operation thereof is disclosed.

Patent CA-2102666-A1 (CA)
Title: Flow control device
Inventor: NAKAZAWA MASAHIKO
IPC: F16K11/16
Filed: 1993-11-08
Abstract: A flow control device has a case formed in a lower portion thereof with a fluid channel and a disk seat at an intermediate portion of the channel. A spindle housed in the case has a disk at its lower end and a rollable member at its upper end and is biased by a spring to press the disk against the seat. The case is provided in an upper portion thereof with a rotary shaft having an upwardly projecting handle or sidewise projecting lever handle. The shaft has a rollable member seat which is annular or circular-arc when seen from above and which is formed with a protuberance for lifting and lowering the rollable member as placed on its seat. Rotation of the shaft moves the protuberance, which in turn raises the rollable member to lift the spindle and hold the disk away from the disk seat. The rotation of the shaft reliably opens or closes the channel, or reliably effects a change-over between fluid channels. The seal face of the disk is less prone to abrasion or damage, will not displace the handle when the disk is thereby closed and is highly durable. The fluid channel within the device can be completely sealed off, so that the device is advantageously usable as a sanitary valve.
