Abstract: A drill screw is composed of a drill portion (11) on a tip of the drill screw, a threaded portion (12) succeeding to the drill portion (11) and a head (13) succeeding to the threaded portion (12) whereby a ridge (14) on the threaded portion (12) threads into an inside wall of a hole while the drill portion (11) drills through a punctured object. The drill screw has cutting edges leading from both ends of a chisel positioned at the center of the tip of the drill screw. Each of the cutting edges forms an arc curving to a head side in an axial direction of the drill screw. Also, a shape of each of the cutting edges forms an arc curving to a back in a rotational direction of the drill screw.

Abstract: The catalytic gas sensor (1) has a heating device (6, 6a, 6b), a temperature sensing device (7; 18, 19) and a catalytically active surface layer (13, 14; 13a, 13b) at which the gas to be measured catalytically reacts exothermically and results in an increase in temperature which is dependent on the gas concentration and which can be measured electrically by the temperature sensing device. A simplified structure with facility for detecting a plurality of types of gases is achieved if the gas sensor (1) has a first and a second measuring region (13, 14; 13a, 13b) having a first and second sensitivity, respectively, if the temperature sensing device (7; 18, 19) is situated on the first and on the second measurement regions and if the first and second measurement regions are formed by surface layers (13, 14) having a first and second catalyst material, respectively, or if the first and second measurement regions (20, 21) each having a catalytically active surface layer are heated to different temperatures by the heating device (6; 6a, 6b). <IMAGE>

Abstract: The invention relates to low fat spreads containing native, that is not substantially denatured, whey protein. 
     It is commonplace to Pasteurise the process stream in spread production under time/temperature conditions as to denature whey protein. The effect of denaturation is precipitation which removes the functional properties of the whey and can lead to a "mealy" product. 
     The invention provides a 35-80% fat phase W/O spread in which the water phase has pH 4.5-5.5, contains 0.5-­10.0%wt of an undenatured whey protein, and has a lactose content below 20%wt of total protein content. 
     Such products have an improved long-term resistance to microbiological spoilage, avoid "mealyness" and utilise functional properties of the whey protein, such as water-binding ability and some effect as an emulsifier.

Abstract: A colour display device has groups of liquid crystal display elements (10) controlled by respective TFTs (16), the groups providing respective different colour outputs, e.g. red, green and blue, and being either interspersed in a single panel (11) with individual elements associated with colour filter elements (30) or in respective separate panels illuminated by differently coloured light. The TFTs are of multilayer structure having semiconductor, gate insulator and gate layers (32, 33, 36). At least one layer thickness of the TFTs is different from group to group and is selected in accordance with the colour light to which they are subjected so as to reduce absorption of that light, and consequently photo-induced currents in their semiconductor layers (32). Significantly reduced absorption is achievable by appropriate choice for example of semiconductor and insulator layer thicknesses based on optical interference considerations. The device can be used as a projection display device.

Abstract: The present invention provides a piston assembly comprising a primary piston (12) and a co-centric secondary piston (14). The pistons (12, 14) are received within a housing (10) for reciprocating movement therein and relative to each other. The housing (10) and the pistons (12, 14) are arranged for operating pressure to be applied to the secondary piston (14) so as to drive both pistons (12, 14) within the housing 10. The secondary piston (14) is provided with means (114) enabling the operating pressure to be equalised across the secondary piston (12) and at least one bypass passage (13) extends through the secondary piston (14). The arrangement is such that upon completion of the stroke of the pistons (12, 14) pressure equalisation occurs across the secondary piston (14) which causes the pistons (12, 14) to separate. The bypass passage (130) becomes fully operable subsequent to pressure equalisation, whereby a fast return stroke is achieved.

Abstract: The invention proposes a pressure regulating valve, in particular for regulating the vacuum in the crankcase. This pressure regulating valve comprises a cup-shaped housing with a bottom part and a lid, there being a diaphragm 14 between these two parts. Arranged on the diaphragm is a hollow cylindrical part 26 which surrounds an interposed valve. This interposed valve is held in its rest position by a compression spring 24. The diaphragm is moved into an upper rest position via a further compression spring 25. If the vacuum in the intake pipe exceeds a certain limiting value, the first valve aperture between the valve seat 17 and the valve plate 18 closes counter to the force of the spring 25. In this valve position, the blow-by gases sucked out of the crankcase are passed through the valve aperture 20. If the vacuum in the intake pipe increases further, the diaphragm 14 moves towards the valve aperture 20 and, at a maximum permissible vacuum, closes this valve aperture too. This two-stage valve is of particularly compact and space-saving construction and can be set to particular pressure limits, depending on the application, by the design of the compression springs and of the cross-section ratios. …<IMAGE>…

When inputting picture data from the manuscript, a layout sheet is set on position data input means such as a data tablet to obtain a specified point on the layout sheet and position data including a trimming range. The position data is delivered to a display together with the picture data. Displaying the picture data and the position data with they being superimposed with each other, the position data is visually confirmed and a necessary correction is made. Another method is to record position data into a recording medium e.g. floppy disk etc. to allow a layout scanner to output the picture data by applying exposure process thereto on the basis of the recording contents of the recording medium.

Abstract: A tristate output driver circuit (30, 40, 50) includes first (Q7) and second (Q8) switches for selectively connecting a logic high voltage source (VH) or a logic low voltage source (VL) to an output terminal (12) in a first, connected mode. Control nodes (14, 16) on the first and second switches (Q7, Q8) are energized in a precise, symmetrical manner to prevent multiple slopes in the output waveform by a precision input stage (31) that includes cascode outputs (Q17, Q18), cascode current sources (Q19-Q20, Q21-Q22) and bootstrapped current sources (32, 34). In a second, tristate mode, the output terminal (12) is electrically isolated from the logic high (VH) and logic low voltage sources (VL). In the tristate mode, the off-switch remains off and the on-switch is turned off by the precision input stage (31) to minimize glitches in the output waveform. A voltage clamping circuit (41, 43) clamps the control nodes (14, 16) of the switches (Q7, Q8) to a voltage more negative than a termination voltage source (Vterm), the logic low voltage source (VL), or the logic high voltage source (VH) in order that the electrical isolation of the tristate mode is maintained regardless of the value of the termination voltage (Vterm).
