Abstract: Pour la production d'angles de trame en technique numérique d'impression l'on juxtapose sans espace intermédiaire, pour la conversion de valeurs de signaux ou de trame (SRW), séparés, à codage digital et contenant l'intensité des gris ou des couleurs de pixels d'un modèle (BV), un grand nombre de cellules en demi-teinte (HZ), de deux types différents au moins et tenant compte de la forme extérieure des angles de trame à produire, dans un bloc de cellules en demi-teintes (HZB) superposé avec i colonnes d'éléments de cellules et j lignes d'éléments de cellules selon un principe d'ordonnancement adapté à l'angle de trame à produire. Les différentes cellules en demi-teintes (HZ) se différencient chacune par rapport aux valeurs de seuil (SW) affectées aux éléments de cellules (ZE) dans la proportion d'au moins un niveau de valeur de seuil. Le bloc de cellules en demi-teintes (HZB) est disposé périodiquement dans un plan de trame nxm (HZF). On peut ainsi calculer les valeurs de seuil (SW) nécessaires à la conversion selon la méthode des pseudo demi-teintes au moyen d'un calcul modulo (mod i, j) à partir du bloc de cellules en demi-teintes (HZB).

Abstract: A copolymer obtained by copolymerizing 35 to 95 % by weight of N-vinylacetamide and 5 to 65 % by weight of other vinyl monomer such as vinyl ester, (meth)acrylate, vinyl ketone, acrylamide, vinyl ether and/or (meth)acrylonitrile in a composition range in which the resulting copolymer is water-soluble and thermoplasticity is molded to give a water-soluble thermoplastic film. The copolymer may also be blended with a water-soluble plasticizer. The film is used as water-soluble packaging material, seed tape base, and printing material base. The film is susceptible to less change in chemical and physical properties after a long storage and hence solubility in water is difficult to change, and N-vinylacetamide has excellent alkali resistance. The film is useful particularly as a packaging material for powder detergents and the like.

Abstract: A process for compressing a gaseous medium, particularly air, in which sucked in gas of a lower initial pressure, particularly atmospheric pressure, is compressed to a predetermined final pressure by means of a compressor driven by the useful side of a thermal engine. The sucked in gas is pre-compressed before entering the compressor and/or the compressed gas is re-compressed after exiting the compressor by a turbocharger. The drive side of the turbocharger is acted upon by the energy of the exhaust gas flow of the thermal engine. In order to increase the overall efficiency of transportable compressor installations in particular, a liquid of a closed or open liquid/steam circulation system, which liquid is under pressure, is evaporated and superheated by the exhaust gas flow of the thermal engine and the superheated steam is fed to the drive side of the turbocharger.

Abstract: A switchable interface for conveniently coupling a network station of the CSMA/CD type to a network having any of a variety of communication media. The invention provides a single interface connector through which connection may be made directly to a twisted-pair medium, using the 10BASE-T protocol, or to a medium of a different type, through an AUI protocol and an appropriate media attachment unit. The interface connector has pin assignments chosen to minimize adverse effects of misconfiguring the station by connecting to a network having a protocol that is different from the one selected in the switchable interface. In one form of the invention, the switchable interface has the ability to determine the protocol being used by the network to which it is connected, and to switch the interface accordingly. Use of the common interface reduces station equipment cost and provides for increased user convenience, since only a single connector is needed to connect to a variety of media types.

Furthermore, an apparatus and method for manufacturing a tape cable, applying the above bonding apparatus and method is also disclosed. In this apparatus and method, a pair of insulating tape sheets (5) are transferred towards electric conductors (2). Prior to the bonding step at a pair of hot rolls (6), the insulating tape sheets adhered to the hot rolls (6) are cut into discrete tapes, and the discrete tapes are prevented from falling from the hot rolls (6) by the static electricity generated thereon. With this apparatus and method, not only a substantial reduction in the cost of materials but also an enhanced productivity of the tape cables can be ensured, and the problem of noise generated by press machines (26) can be avoided.

Abstract: A high-precision coordinate input apparatus having a small circuit construction. A vibrating pen transmits vibration onto a vibration transmitting tablet, then vibration sensors provided at corners of the vibration transmitting tablet detect the vibration. One of the vibration sensor is used as a reference sensor. Time difference between vibration detecting timing by this reference sensor and detecting timing by one of the other sensors is measured. This measurement is performed on all the vibration sensors with respect to the reference sensor. The obtained time differences are converted into distance differences for calculation of the coordinates of the position in which the vibration has been generated. The vibrating pen has a power source and it operates independent of the apparatus main body. The vibrating pen changes its frequency of vibration in accordance with the voltage of the power source. The apparatus main body captures this change in the vibration frequency and obtain the state of the vibration pen power source.

Abstract: A fluid cutting system of improved configuration provides a high-velocity fluid that is rotated about a first axis (preferably a horizontal axis) on a moving trolley (21). The trolley is rotationally supported about a second axis (preferably vertical). The trolley travels upon a pair of arc-shaped tracks (19,20,29,30) and is driven by a motor drive. The trolley has a pair of arc-shaped tracks that support the fluid jet nozzle (38). The fluid nozzle is thus rotatable about two axes, thereby emitting a high-pressure stream of fluid for adjustable cutting. A workpiece positioning frame (12) has a fish section holder (46) that can be elevated or moved laterally with respect to the cutting system.
