Patent CA-2186435-A1 (CA)
Inventor: MATTHEW KERRY RAY
IPC: G09B21/00
Filed: 1996-09-25
Abstract: An IC card reader that can output data in an audio form. The IC card reader includes a small portable case in which an IC card can be inserted. A microcontroller powered by a battery within the case reads the stored data from the IC card and encodes the read data into a series of voice commands. A voice synthesizer circuit produce a synthetic speech signal from the encoded data. An amplifier within the case is connected to the voice synthesizer circuit for amplifying the synthetic speech signal. A speaker also internal to the case is responsive to the synthetic signal for outputting an audio signal corresponding to the stored data through small holes in the front face the case. A membrane switch within the case can be closed using a push button on thefront face of the case to electrically connect the microcontroller to the card. Thus, in use of the IC card reader, when the button is depressed to close the switch, themicrocontroller is caused to interrogate the card so that the data stored on the card is read into the microcontroller. The microcomputer produces a synthetic speech signal that is amplified by the amplifier and output by the speaker as synthetic speech which can be heard by the user by holding the card reader with the speaker against the user's ear.

Abstract: The addition of fibrous mixtures in intimate mixtures with particulates for fracturing and gravel packing decreases or eliminates the undesirable flowback of proppant or formation fines while stabilizing the sand pack and lowering the demand for high polymer loadings in the placement fluids.  Fibers are useful for forming a porous pack in the subterranean formation.  In some cases, channels or fingers of void spaces with reduced concentrations of proppant may be introduced into the proppant pack.

Abstract: Blood supplied from a blood-drawing line is stored in a main reservoir. Above the main reservoir there are located four sub-reservoirs with their internal negative pressures controllable by means of a controller.  Via sub-suction lines bloods in the heart of a patient, etc. as well as blood emitted in the site being operated is sucked into the interiors of the sub-reservoirs.  The bloods sucked in the sub-reservoirs are guided into a main reservoir through guidance means.  A pool of blood stored in the main reservoir is fed back to the patient via a pump, artificial lungs and an arterial filter. A centrifugal pump is used as the pump. It is thus possible to provide a compact and inexpensive pump-oxygenator system which reduces the amount of the blood to be transfused, causes lesser damage to blood, excels in the ability to be manipulated and quickly used, and has little, if any, possibility of interfering with operations by an operator.                         .

Abstract: The purification of pentafluoroethane (HFC-125) which is composed of a process A, in which an unpurified mixture (1), containing at least chloropentafluoroethane (CFC-115) and pentafluoroethane (HFC-125) is reacted with hydrogen (4) in the presence of a catalyst in gas phase to reduce the said chloropentafluoroethane (CFC-115); and a process B, in which a reaction mixture produced by the preceding reaction is separated into a first mixture (3) composed mainly of hydrogen and a second mixture (2), composed mainly of pentafluoroethane (HFC-125). In this method, purification is performed by adding the said first mixture (3) to the said unpurified mixture (1) in a state that the hydrogen chloride is removed from the first mixture (3) in process B until the level of hydrogen chloride drops to 0.5 or less than that of CFC-115 in the unpurified mixture (1) in the molar ratio, or hydrogen chloride is removed from the said reaction mixture until, when mixed with the unpurified mixture (1), the level of hydrogen chloride drops to 0.5 or less than that of CFC-115 in the mixture in the molar ratio.      Thus, CFC-115 can be exterminated (or removed) cheaply and efficiently without decreasing it's reactivity (or activity) and a high yield of HFC-125 can be obtained.

Patent CA-2199449-A1 (CA)
Inventor: THOMPSON HARRY
IPC: A61F6/04
Filed: 1997-03-07
Abstract: A contoured micro-condom has been designed together with a self-contained easy and carefree combination applicator and package. The micro-condom, which has a thin impervious sheath in the general shape of the glans penis head contours, has a thicker elastic band around its open end. The micro-condom's band is positioned securely and is contained within an apperature within the retainer frame of the applicator/package, the apperature having sufficient width to accommodate the diameter of a nominal erect glans penis head. In this position, the contoured or other micro-condom is covered at its closed end by a unidirectional releasing top cover, and is covered on its open end by another removable lower cover. Thus, it is protected from the outside environment, and ready to be applied using a few quick, easy and carefree steps. Quick removal of the lower cover allows access to the open end of the micro-condom which is placed over the erect glans penis head as it pushes through the unidirectional releasing top cover and releases its band from the frame of the applicator/package. The novel unidirectional releasing cover is specially constructed in material and/or geometry, to allow the cover to change shape and size easily with the application of pressure in one direction while resisting a shape or size change from the other direction. This allows the applicator to also act as a safe packaging for the micro condom.

Inventor: RYRKO BRUNO F
IPC: G01P9/04
Filed: 1996-05-30
Abstract: A micromechanical rotation speed sensor based on the principle of Coriolis contains two flat, mutually flush and superimposed oscillators (1, 2) that may be electrostatically made to oscillate with contrary phases on flat support structures (4a, 4b, 33c, 33d) mutually separated by a very small driving capacitor gap (30). By an appropriate choice of the resonant frequency of the support structures, and by leaving a substantially larger distance between the oscillators (1 and 2), larger oscillation amplitudes and thus a high oscillation quality may be achieved that are not limited by the narrow driving capacitor gap (30) that would be required to achieve a good degree of excitation at small excitation voltages. Both oscillators preferably consist each of two bonded parts that are electrically insulated from each other, suspended on springs (8o to 83, 80' to 83') within a frame and designed in such a way that the oscillators can only describe rotary movements and all linear movements of the oscillators in the direction ~z are suppressed.

Title: Frame display control in an image display having a liquid crystal display panel
Inventor: OGAWA YASUNORI
IPC: H04N5/46
Filed: 1997-12-03
Abstract: An image display device having a liquid crystal display panel in which display picture elements are arranged according to a dot matrix form includes a control circuit that controls the drive of a source driver and gate driver such that writing of signals for frame display in a horizontal direction is performed during the vertical blanking interval of input image signals. During the vertical blanking interval, the control circuit writes to the source driver each source selection signal of picture elements that are to display the horizontal frame and holds this data. The control circuit then generates sequential gate selection signals from the gate driver while supplying the held output of the source driver to the sources of the picture elements, and supplies horizontal frame display signals to the picture elements.
