Abstract: This invention relates to transferable pressure-sensitive adhesive films in the form of a pad. 
     Dry pressure-sensitive adhesive films known in the art suffer from several disadvantages, e.g., the need to dispense from a special dispenser, the generation of waste material, the limitation on possible shapes of the adherent area. It would be desirable to develop a dry pressure-sensitive adhesive film that would not have the foregoing disadvantages. 
     This invention provides a dry transferable pressure-sensitive adhesive film, which in the form of a pad, and is coated on a plurality of stacked, bothsided but differently adhesion-release treated backing materials, while forming adhesive-free areas on each backing materials and being in each case, in contact with the other side of the adjacent backing material in the pad, whereby the most upper backing sheet of the pad can be readily peeled off from the pad together with the attached adhesive film and can be pressed onto a substrate, on which an adherent surface film will remain on peeling off the backing material from the adhesive film.

Abstract: An internal exhaust fan (56) propels internal solvent-laden air across a burner (66) where it combusts, causing a heat rise. Heated, combusted air is routed to a recirculating supply air fan (50) which provides pressurized heated air for air bars (28a-28n, 30a-30n) for drying a web. Heated air in excess of that required to dry the web is vented externally and helps to maintain desired solvent concentration levels. Variable parameters such as fan speed, burner temperatures, air box pressures, exhaust air rate, solvent concentration, supply air flow, supply air temperature and damper position are monitored, and the components are actuated to effect a high level of clean up efficiency. The control system provides for the coordinated control of the exhaust fan speed, damper positions, and burner firing. The control system utilizes a computer in real time processing to monitor and control the electrical and electromechanical components.

Abstract: An educational toy (10) having a dodecahedron shape is formed with a different visual display on each planar face (17-28). A position sensing mechanism (50) is oriented inside the toy (10) to inform a microprocessor (62) which one of the planar faces (17-28) is in the "up" position. As the toy (10) is turned or moved a signal is generated to "power on" and a musical tune is played. When one of the planar faces (17-28) is stopped in the "up" position, the position sensing mechanism (50) informs the microprocessor (62) and an aural response corresponding to the visual display is transmitted through a speaker (44). If the toy (10) is left alone for a specified period of time, a warning tune is transmitted. If the toy (10) is still not moved thereafter, the toy (10) will automatically "power off".

Abstract: A semiconductor device has a first functional block (202) for performing data processing and a second functional block (206, 302) for storing various information necessary for performing the data processing. The first functional block and a functional element section of the second functional block are directly formed on the semiconductor substrate (100). A memory cell array of the second functional block is formed above the first functional block and the like with a passivation film (110) interposed therebetween. The memory cell array has conductive wires (112) in the X direction and conductive wires (115) in the Y direction. The conductive wires in the X and Y directions are previously made conductive at optional three-dimensional intersections therebetween to thus form a mask ROM. An insulating film which is destroyed upon the application of a voltage is formed at the three-­dimensional intersections to thus form a PROM. A ferroelectric member (117) which is polarized in accordance with an applied voltage direction is formed at the three-dimensional intersections to thus form an EEPROM.

Abstract: A video transformation and filtering system generates for each source image data point a plurality of target image addresses indicating a displacement between a point at which the source image data point maps into the target image and each data point of the target image which is affected by the source image data point. By providing either sequentially or in parallel a separate processing for each target image data point that is affected by a current source image data point values for all of the target image data points can be generated from a single pass of the source image data points. By effectively providing the filtering in the domain of the target image instead of the source image a single filter function with a fixed number of points in the target image domain can be used to attain low pass filtering of the resulting target image irres­pective of the degree of size compression of the video image.

Abstract: Methods and apparatus for achieving high frequency (HF) modem communi­cations. A predetermined plurality of frequency hopped, digital phase shift keying modulated tones are generated at a predetermined number of pseudo-randomly gener­ated frequencies during a successive plurality of time frames. The phase of the tone at each frequency during a particular time frame is differentially modulated to one of a predetermined number of new phases using the phase of the tone at the same fre­quency in the previous frame as a reference. The tones are transmitted in the high frequency (HF) band, and then received and converted into digital signals. The digi­tal signals are processed to determine the phase of the tone at each transmitted fre­quency. This may be accomplished by means of a Fourier transform filter. Finally, the phase of each tone is compared to the phase of the tone received at the same fre­quency in the previous frame to decode the received signals, and hence accomplish the desired communications. The present invention provides for communications methods and apparatus which achieves HF skywave communications at high data rates with low bit error rate performance. The invention employs the use of frequen­cy hopped digital phase shift keying and the convolutional coding that overcomes the dispersive nature of the HF channel and achieves the high data rate without resorting to channel equalization techniques. The performance of the modem of the present in­vention is not limited by the multimode multipath characteristics of the HF path. This is due to selection of a frequency dwell time that is significantly less than the multipath differential times of arrival, and a frame time of the waveform that is long­er than the maximum multipath differential times of arrival.

Abstract: A connector for coupling pressure-sensitive or brittle elongated conducting elements such as optical fibres or other elements made of ceramic oxides, glass, plastic or paper. A resilient connecting member (10) of generally cylindrical form is placed into an expanded state during production, resulting in an enlarged internal diameter, and is temporarily held in this expanded configuration. The interior (15) of the expanded member thereafter received a pair of segments, one into each end, of conductive elements which are to be connected in end-to-end engagement. When this engagement is achieved, the retaining member is released either by vibration, mechanical release or other means, to allow the connecting member to return under its inherent spring force to its original diameter and configuration. In doing so it closes over and grips the inserted ends of the conductive elements in splicing relationship, creating a conductive joint.
