Patent CA-2053657-A1 (CA)
Inventor: AKIYAMA TAKEHIRO
IPC: H03L7/199
Filed: 1991-10-17
Abstract: A PLL frequency synthesizer includes a reset circuit which determines whether or not an oscillator starts to normally generate an oscillation signal in response to a power save signal which intermittently operates the oscillator in a standby mode and which outputs a reset signal to a prescaler when it is determined that the oscillator normally generates the oscillation signal. A hold circuit prevents a frequency-divided signal from the prescaler to a programmable counter and an initial phase detection circuit until the prescaler is reset to an initial state in response to the reset signal and starts to normally generate the frequency-divided signal.

Title: Solid-state electrochromic device with proton-conducting polymer electrolyte
Inventor: HO KUO-CHUAN
IPC: G02F1/1524
Filed: 1991-12-04
Abstract: A solid-state electrochromic device is disclosed comprising tungsten oxide-Prussian blue complementary configuration in combination with a proton-conducting polymer electrolyte.  A novel proton-conducting copolymer, especially useful in transparent electrochromic cells, comprising the reaction product of a vinyl sulfate monomer with a comonomer selected to form an alternating copolymer, such as vinylpyrrolidone, is disclosed.  Novel transparent complementary electrode materials for electrochromic cells are disclosed, of the general formula [M1]4[M2(CN)6]3 wherein M1 may be indium, gallium, gadolinium, lanthanum, and M2 is iron.  Unlike Prussian blue (where M1 and M2 are both iron), the complementary electrode materials of the present invention are stable, and do not have to be precharged.  An electrochromic transparency comprising an electrochromic film and an ion-conductive layer disposed between a pair of electrodes is disclosed wherein the optical properties and electrochromic efficiency are improved by means of a metal grid electrode, wherein adhesion of the metal grid to an acidic polymer electrolyte is improved by means of a primer coating comprising a copolymer of acrylamidopropane sulfonic acid and acrylic acid.

Title: Solution doping of porous preforms
Inventor: BARTHOLOMEW ROGER F
IPC: C03B37/014
Filed: 1991-12-12
Abstract: Abstract of the Disclosure Disclosed is a method of forming a doped glass body. The glass body is formed by adding a dopant to a glass preform, at least part of which has interconnective pores. The porous preform is immersed in a solution of a salt of the dopant dissolved in an organic solvent having no OH groups.  The solvent is removed, and the porous glass preform is heat treated to consolidate it into a non-porous glassy body containing the dopant dispersed throughout at least a portion of the body.  An OH-free solvent is selected because of its beneficial effect on the preform during the drying step.  Whereas OH-containing solvents such as water and alcohol caused cracking and/or flaking of the outer surface of the porous preform following the drying step, an undamaged surface is formed by the present invention.

Patent CA-2093955-A1 (CA)
Inventor: JOSEPH DANIEL R
IPC: B29C48/92
Filed: 1993-04-13
Abstract: In a blown film extrusion system in which film is extruded as a tube from an annular die and then pulled along  a  predetermined  path,  an apparatus  is provided for gauging and controlling the circumference of the extruded film tube.   At least one transducer, preferably ultrasonic, is mounted adjacent the extruded film tube for transmitting and receiving interrogating pulses along paths normal to the extruded film tube, and   for   producing   a   current   position   signal corresponding to the circumference of the extruded film tube.   The current  position  signal  is continuously compared with at least one previous position signal, preferably  with  a  computer  program  resident  in  a controller  memory.     If  at  least  one  preselected condition is violated, the current position signal is disregarded in favor of an estimated position signal. The quantity of air within the extruded film tube is varied  in response  to  either  the  current  position signal or the estimated position signal to maintain the extruded film tube at a preselected circumference.  The transducer may be mounted to an adjustable sizing cage, and  is  thus  moveable  inward,  outward,  upward,  and downward relative to the extruded film tube as changes are made in its circumference or frostline position.  A pair of controllers may be employed to establish two minimum  circumference   values,   and   two   maximum circumference values.   If a collapsing or overblown extruded film tube is detected, the system goes into override, and the flow of air is either accelerated or decreased to counter the alarm condition.   The system of  the present  invention  also allows for automatic startup.    In a  startup  mode,  the  current  position signal is continuously compared with a selected minimum circumference threshold.    Once  the  selected minimum circumference  threshold   is   exceeded,   the  system switches  to  an  operating  mode  which  continuously compares the current position signal with a selected setpoint value to maintain the extruded film tube at a desired circumference.
