Patent CA-2040897-A1 (CA)
Inventor: HORSLEY PETER B
IPC: B64G1/00
Filed: 1991-04-22
Abstract: ABSTRACT            In a propulsion system for space vehicles, jets or reaction motors are commonly used to provide a thrust or an unbalanced force. The mass used for reaction is the fuel, and the fuel is launched into orbit along with the space vehicle, at great expense. My invention circumvents this expense by using the same mass over and over again. The mass in my invention is in the form of basic charged particles of matter. These are accelerated to high velocities such as half the speed of light or greater. When the particles are exhibiting extra mass due to mass-energy equivalence, the particles are made to change direction by 180 degrees, thereby exerting an unbalanced force on the deflecting duct in the device. The particles are then decelerated to normal speeds and the cycle is repeated using the same mass.The energy used is derived from solar panels energized by the sun.

Patent CA-2053237-A1 (CA)
Inventor: DORFI KURT
IPC: G01T1/14
Filed: 1991-02-22
Abstract: The detector system includes three substantially similar detectors each of which includes an ionization chamber having a pedestal therein mounting a charged electret. Two chambers are completely sealed except for an equalization aperture. However, gamma rays produce ionization that neutralizes portions of the electret charge in these sealed chambers. The third detector has filtered inlet openings, which permit entry of radon gas, and responds to gamma rays and radon gas. Each detector is a canister including a lid having a round base surrounded by a cylindrical wall. The canister body is a circular base surrounded by a cylindrical wall that nests within the lid with a telescopic fit. A cylindrical pedestal assembly rests on the lid base and concentrically sandwiches the canister body between the pedestal assembly and lid. A press-fit holds these three elements together.     The charged electret is mounted on the platform by a retaining collar that holds the electret with a press-fit. By keeping the three units together until the test starts, one of the sealed containers can have the charge on its electret measured at the beginning of the test in order to provide a baseline measurement. At the end of the test, the charges on the other two electrets are measured and provide a gamma ray background measurement at the test site and a combined radon gas/gamma ray measurement. By appropriate calculations, an accurate measure of radon concentration at the test site can be obtained. As an alternative, only two canisters need be used if the baseline measurement is not necessary.

Patent CA-2056653-A1 (CA)
Inventor: SUNAMI MASAKI
IPC: A61K31/46
Filed: 1991-11-29
Abstract: Disclosed is a preparation for transdermal drug administration comprising a flexible backing layer and a pressure-sensitive adhesive layer containing a local anesthetic in an amount of 40-65 % by weight based on the total weight of the pressure-sensitive adhesive layer. Since the ratio of the amount of undissolved local anesthetic (Ac) to that of dissolved local anesthetic (As), Ac/As, in the pressure-sensitive adhesive layer is determined to be in the range of 0.1-1.8, the preparation for transdermal drug administration is superior in self-adhesiveness and leaves no adhesive material upon removal from the skin. In addition, burst-like release of the undissolved drug from the pressure-sensitive adhesive layer immediately after application to the skin permits rapid appearance of the anesthetic effect, which enables wide clinical application of the preparations of the present invention.

Filed: 1992-04-03
Abstract: A projection television provided with a wavelength-selection-type rear projection screen, the transmittance of which is relatively large when the wavelength of incident light is equal to or longer than a predetermined value, but the transmittance of which is relatively small when the wavelength of incident light is shorter than the predetermined value.  Moreover, the projection television most effectively utilizes power of each CRT by increasing the beam current of each of the red and green cathode ray tubes.  With such a screen of which the transmittance is relatively high when incident light is blue light, but the transmittance of which is relatively low when the incident light is red or green light, the magnitude of the beam current of each of the red and green cathode ray tubes, of which the efficiency in emitting light is relatively large, can be increased.  Thus, contrast measured under presence of external light irradiated on the screen can be increased without decreasing luminance.

Abstract: ABSTRACT            The focus acquire system on optical disk recorder as well as other optical systems, signal processes a focus error signal FES to produce a modified FES which has a peak amplitude occurring  closer  to  a  desired  focus  position  than  the occurrence of peak amplitude of the FRS.  The modified FES also is signal processed to sharpen or slim the peak portion such  that  increasing  the  amplitude  of  the  modified  FES reaches an amplitude detection threshold closer to the true peak of the modified FES,  and hence closer to the desired focus position than if  the  amplitude detection threshold were used on the FES.  In a preferred form of the invention, FES is differentiated to produce a differentiated FES, then the differentiated FES is subtracted from FES to produce the modified FES.

Abstract: An mxn (m > n) output Packet Switch Unit is implemented by using an nxn Packet Switch Module and an m:n Concentrator. The arriving packet cells are supplied from the m Concentrator inputs to the n Concentrator outputs in a "first-in first-out" (FIFO) sequence. The Concentrator provides for buffering of arriving packet cells on the m Concentrator inputs in excess of available packet cell positions in the n Concentrator outputs until they can be supplied to a Concentrator output in the FIFO sequence. In turn, packet cells from the n Concentrator outputs are supplied to n inputs of the Packet Switch Module which supplies them to appropriate output destinations associated with the n outputs of the Packet Switch Module. A plurality of the Concentrator-Based output Packet Switch Units is readily employed to implement any "larger" Packet Switch architecture.

Abstract: A  data  processing  system  is  responsive  to  a plurality of input languages, each language adhering to a prescribed syntax.   The presence of defined portions ("For" keys) in the incoming data indicate a vote  for  the presence  of  a  language  and  the presence of other defined portions ("Against" keys) indicate  a  vote  Against  the  presence  of  the language.  The system performs the following method for identifying the input language: analyzing,  for each expected language, the syntax of an incoming block of data to identify For and Against keys in the  block  of  data;   providing  For  and  Against tallies for each expected language in response to the analysis, each tally being a summation of key entries, each key entry comprising an identified key count multiplied by a skew, a skew value indicating the importance of the key in the syntax and in the context of said block of data, the For tally summing entries of For keys and the Against tally summing entries  of  Against  keys;  comparing  the  For  and Against tallies to determine whether or not they are so close as to signal uncertainty; and, based upon a further syntactical characteristic of block of data, resolving the uncertainty and indicating a value based on one of the tallies:  indicating a value derived from the larger of the tallies in the event of no uncertainty between the tallies; and deciding, based upon the indicated value for each  expected language, the identity of a received language.
