Abstract: When the display is to be erased from active matrix-type liquid crystal display elements which have a source bus drive circuit (16) and a gate bus drive circuit (17), pixel signals for turning the pixels off are supplied in an amount of one line to the source bus drive circuit and, at the same time, a clear signal (CL) is given to a gate bus drive circuit (17) to apply a voltage simultaneously to all gate buses (15, to 15 m ) to turn on the transistors (13) in all of the pixels. Provision is made of a power source holding circuit (22) for holding the power of the power source (V i ) supplied to the gate bus drive circuit (17) for a predetermined period of time even after the power source is turned off, and a voltage drop detect circuit (24) for detecting the turn-off of the power source. A clear signal (CL) is produced in response to the detect signal and is sent to the gate bus drive circuit (17). In response to the clear signal, the gate bus drive circuit supplies a voltage for turning on the transistors (13) of all pixels simultaneously to all of the gate buses to erase the display in a short period of time after the power source is turned off.

Abstract: The known windscreen wiper arms are designed in such a way that the inertia forces which act at the centre of gravity of the part which can be folded away from the window pane reduce the contact pressure of the wiper blade as the angular speed increases, which leads to a worsening in wiping results. A windscreen wiper without this disadvantage has an overall centre of gravity (S) of the parts (WA) which move perpendicular to the window pane (SCH) which, viewed from the window pane, always remains above a plane (E) which goes through the folding axis (KA) and to which the axis of rotation (WDA) of the wiper is perpendicular. <IMAGE> In order to improve the wiping results, wiper bars are provided whose centre of gravity is located on their axes of rotation. In addition, the inertia forces of the wiper rubbers are transmitted directly to the wiper arm (WA). <IMAGE>

Abstract: A MOSFET device having a near-micrometer or submicrometer channel length and designed to operated under conditions that cause generation of hot carriers is carbon doped in the silicon substrate (12) at the gate oxide(16)-silicon interface (18). The oxide-­silicon interface can include hydrogen atoms. These atoms are mostly bonded to carbon atoms, more strongly than hydrogen bonds to silicon, so that hot carriers are less likely to dissociate the hydrogen atoms and form hot carrier trapping sites at the interface. Hot carrier aging is thus substantially reduced. This capability is particularly useful in submicrometer devices, avoiding need to reduce normal operating voltages.

Abstract: Interior walls with easily cleanable surfaces are constructed from wall panels (11) and panel connection assemblies (12). The panels are fabricated from fire resistant materials (21) sandwiched between outer metal surface sheets (22). The panel connection assemblies (12) have a pair of elongate members (24), each having a bottom section and side sections forming a channel, from which outwardly extending flanges (27) are arranged to over-lay adjacent panels. The pair of cooperating elongate members are secured together and the channels are covered by cover plates (33). Each panel edge includes a recess for accommodating a flange (27) and a cover plate (33) to form a smooth easily cleanable surface and each surface metal plate extends the full width of its respective panel to contact the side section of the elongate member. 
     The structure provides an easily cleanable internal surface which is extremely resilient to mechanical damage and fire damage. Heat causes the surface metal plates (22) to expand resulting in force being applied to the U-­shaped elongate members (24), thereby preventing the panels from falling out of position. Under extreme circumstances, individual panels may be dislodged, without resulting in complete collapse of the structure.
