However, such preview windows are not representative of how the command will impact the entire document. The invention provides a method and system of efficiently and effectively previewing the impact of User commands on the entire document by executing User commands as they are identified. Leaving the menu open, the User is able to identify successive commands until the desired result is reached. Embodiments are described for execution of general commands, text editing commands, relocations of margins or guidelines, and relocations of graphic objects.

Abstract: A pressure switch comprises a first dielectric sheet having a first and second surface; and has two half circuits carried on the first surface of said first dielectric sheet. A second dielectric sheet overlies the first dielectric sheet. The second dielectric sheet has a plurality of switch closures carried thereon and facing the first dielectric sheet. The switch closures are normally spaced from the half circuits on the first dielectric sheet, and are deflectable into contact with the half circuits under an externally applied force.

Abstract: An accumulating whistling vent for indicating a level of liquid in a tank having a vent line is disclosed. The whistling vent includes a whistle housing reservoir which has mounting tubes extending from either ends. A whisle is housed in the whistle housing reservoir by insertion into one of the mounting tubes. The whistling vent is coupled between the vent line of the tank such that the tube containing the whistle is closest to the tank. As liquid is introduced into the tank an audible signal is produced by the whistle. Once full, air flowing from the tank through the vent line is replaced by the incoming liquid, thus muting the whistle. Excess liquid is accumulated in the reservoir prior to discharge from the vent line, thereby providing additional time to respond to the change in audible signal. In a preferred embodiment of the invention, a transparent reservoir is used to provide a visual indicator in addition to the change in audible signal.

Abstract: A plug connector for establishing an electrical contact between first and second conducting track carriers, in particular between a flexible conductor foil and a circuit board, comprises a plug part that has a plug housing provided with a cam surface. The first conducting track carrier is shiftably mounted to the plug housing such that it can be shifted starting from an advanced initial position into a retracted contact position and parallel to a plug-in direction of the plug part. The plug connector further comprises a socket part that includes a socket housing, a pressure application spring and the second conducting track carrier which is received in the socket housing. The pressure application spring has two ends, one end of which forms a supported end received in the socket housing and the other end forms a pressing end that cooperates with the first conducting track carrier if the latter is in the contact position.

Abstract: In a production process of an MR head using the tunnel junction film basically consisting of a free layer, a barrier layer, and a pinned layer, the resistance between the free layer and the pined layer reduced beforehand and increased afterward up to a resistance value necessary when actually used. While the resistance between the free layer and the pinned layer is low, current can easily flow, suppressing charge up, thus preventing insulation destruction of the barrier layer. This significantly increases a production yield of a recording/reproduction head using a ferromagnetic tunnel junction element.

Abstract: Using a mask opening a gate region, an undoped GaAs layer is selectively etched with respect to an undoped Al0.2Ga0.8As layer by dry etching with introducing a mixture gas of a chloride gas containing only chlorine and a fluoride gas containing only fluorine (e.g. BCl3+SF6 or so forth). By about 100% over-etching is performed for the undoped GaAs layer, etching (side etching) propagates in transverse direction of the undoped GaAs layer. With using the mask, a gate electrode of WSi is formed. Thus, a gap in a width of about 20 nm is formed by etching in the transverse direction on the drain side of the gate electrode. By this, a hetero junction FET having reduced fluctuation of characteristics of an FET, such as a threshold value, lower a rising voltage and higher breakdown characteristics.

Abstract: A method of designing a layout of an integrated circuit is composed of providing a macro in which a macro circuit is to be accommodated in a top level hierarchical cell; and determining a layout of an interconnecting path provided on the top level hierarchical cell. The interconnecting path is used for transmitting a signal from a first position located outside the macro to a second position located outside the macro such that the interconnecting path passes through the macro. The interconnecting path includes first and second buffers placed substantially on a boundary of the macro, a first interconnection connecting the first position to an input of the first buffer, and a second interconnection connecting an output of the second buffer to the second position. An output of the first buffer is electrically connected to an input of the second buffer.

Abstract: For a connection between two multiple electrical conductors, a connecting arrangement is proposed which consists of a casing that can be disassembled in such a way that even a multiple electrical conductor that has already been laid, for example a round cable, can be connected to additional electrical conductors at any desired point. Under these circumstances, electrical contact with the individual electrical conductors of the multiple conductor that has been laid is made by means of insulation-cutting terminals disposed in the said casing in which an eccentric, which is likewise disposed therein in a rotatable manner, successively forces the electrical conductors, without great expenditure of force, into the insulation-cutting terminals disposed in the form of a circle around the eccentric, and brings them into electrical contact with the severing of the insulation.
