Abstract: A display device employing electro-optical fluids which contain dielectric particles having an electro-rheological effect in an electrically insulating medium is proposed. The display device includes a hollow housing body, two opposing faces of which have respectively at least transparent opposing part and in which the electro-optical fluids are contained. Transparent conductive layers are formed on at least part of respective faces of the two opposing faces of the housing body. Optical shutters are formed in the housing body by chain-like structures of the dielectric particles which, by applying voltage to the transparent conductive layers, are arranged to be connected to each other in the direction along an applied electric field. Desired characters, numerals, figures and the like can be displayed by operating the optical shutters. The transparent conductive layers can be formed on an entire surface or formed as line conductor. Otherwise, the transparent conductive layers can be stacked to form a multilayered structure, thus enabling the display device to switch selectively displayed shapes.

Abstract: An exchange accessory useful with monorail and other types of catheters has a hollow, elongated sleeve for insertion into a Tuohy-Borst connector or the like, and an enlarged head at its proximal end to restrain the sleeve from advancing with the catheter into the connector. The sleeve is slidably mounted on the catheter shaft so that it may be interposed between a sealing member within the connector and the catheter. The internal diameter of the sleeve is greater than and complementary with the external diameter of the catheter shaft to define a space about the catheter shaft sufficient to allow backbleed of blood therethrough in a controlled manner. 
     In one embodiment, the sleeve has a slotted head to accommodate a guidewire which may extend in parallel to the catheter shaft, for example, when used with a monorail type catheter. The slot permits the guidewire to extend proximal to the connector without bending or kinking. In another embodiment, the exchange accessory may be assembled onto a conventional catheter shaft. As a modification to these embodiments, an aperture may be provided for selectively engaging the catheter by closing the connector on the sleeve with the aperture aligned with a sealing member of the connector.

Abstract: A speech coding system robust to frame erasure (or packet loss) is described. Illustrative embodiments are directed to a modified version of CCITT standard G.728. In the event of frame erasure, vectors of an excitation signal are synthesized based on previously stored excitation signal vectors generated during non-erased frames. This synthesis differs for voiced and non-voiced speech. During erased frames, linear prediction filter coefficients are synthesized as a weighted extrapolation of a set of linear prediction filter coefficients determined during non-erased frames. The weighting factor is a number less than 1. This weighting accomplishes a bandwidth-expansion of peaks in the frequency response of a linear predictive filter. Computational complexity during erased frames is reduced through the elimination of certain computations needed during non-erased frames only. This reduction in computational complexity offsets additional computation required for excitation signal synthesis and linear prediction filter coefficient generation during erased frames.

Abstract: Patient airway baseline pressure levels are controlled in a ventilator having a pneumatically controlled exhalation valve without an external supply of pilot pressure, by supplying an internal source of controllable pilot pressure for operating the exhalation valve. The pressure of pressurized air supplied by an internal pump can be electrically controlled by pulse width modulation of a variable pulse duration signal. A second source of pressurized air for pilot pressure is provided, and in one embodiment is a reservoir provided for receiving pressurized air from the pump and from the exhalation circuit. A valve is connected to the pump means and the reservoir for receiving pressurized air from the pump in a first position, and for receiving pressurized air from the reservoir in a second position. When the valve means is in the second position, pressurized air is delivered at a pressure which is the greater of the pressurized air supplied by the pump means or the gas flow from the exhalation circuit.

Abstract: Apparatus for color printing which employs a conditioning roller (50) for conditioning a dry toner image (24). An intermediate member (20) first acts as a receptor for marking particles representing an image, whereby the marking particles may be deposited directly or indirectly on the member. The member is then exposed, via an internal heat source (32), to an elevated temperature sufficient to cause the melting and coalescing of the marking particles. The tackified image (30) is condition by a conditioning roller. The rollers create a thinner, more cohesive image without degradation of the image for subsequent imaging. In a multicolor printing configuration, the intermediate member is advanced and at least a second color marking particles is deposited onto the previous image. The image is again conditioned by the conditioning roller. When the multicolor, tackified image is completed, or for monochrome printing, when the single color image is completed, the intermediate member is advanced so as to place the multicolored tackified marking particles present on the outer surface thereof into intimate contact with the surface of a recording sheet (26).

Abstract: An automatic video signal level circuit comprises a contrast control circuit, black level compensating circuit, black level detecting circuit, processing circuit of a detected black level for generating a control signal to the black level compensating circuit, white level detecting circuit, and processing circuit of a detected white level for generating a contrast control signal. When the black level is higher than a predetermined level, the black level is lowered. When the black level is lower than the predetermined level, the black level is raised. When a white level is detected and found the white level is higher, contrast is lowered. When the white level is lower, the contrast is raised. Thus this structure has such an algorithm that can always optimize the contrast and the black level.

Abstract: A sleeve assembly (42) for reducing the thermal conduction heat load from the bellows penetration tube (14) to the helium vessel (4) of a superconducting magnet assembly. The sleeve assembly is designed to force helium boil-off gas to flow in intimate contact with the bellows convolutions. The helium boil-off gas thereby intercepts or removes a portion of the heat that would normally be conducted from the bellows convolutions to the helium vessel. The sleeve assembly consists of a circular cylindrical rolled tube (44) made of laminated thermosetting material. The outer diameter of the tube (44) is wrapped with tape in a helical pattern. The diameter of the sleeve and the thickness of the tape wrapping are selected so that the outer circumferential surface of the helically wrapped tape abuts the inner diameter of the bellows (14). The sleeve is fabricated with a relatively small thickness to minimize thermal conduction load. The successive turns of the helical strip of tape are separated by a helical channel 
   which forms a helical flow path for the helium boil-off gas as it flows toward the boil-off gas outlet. As the helium gas spirals around the sleeve assembly, the gas cools the bellows convolutions and the sleeve instrumentation wiring, thereby minimizing thermal conduction losses. Also, the gas will travel inside the bellows convolutions to minimize helium gas conduction inside the convolutions.

Abstract: In the terminal metal fitting assembling structure, a projecting portion is provided in a plate-like overlap portion which is formed in a second terminal metal fitting. In addition, the position of provision of the projecting or pressing portion is set outside of an area A with which the head portion of a tightening bolt is directly contacted. Due to this, when the two terminal metal fittings are tightened by the tightening bolt, a plate-like overlap portion formed in the first terminal metal fitting is flexibly deformed and is pressed through the projecting or pressing portion against the plate-like overlap portion of the second terminal metal fitting, so that the two terminal metal fittings can be strongly contacted with each other by means of a resilient force generated by the flexibly deformed plate-like overlap portion. This makes it possible to increase the contact pressure between the two terminal metal fittings. Still further, since the projecting or pressing portion is not tightened directly, even if the two terminal metal fittings are tightened excessively by the tightening bolt, the projecting portion can be prevented from being crushed.
