Patent EP-0098154-A2 (EP)
Inventor: EBATA YASUO
IPC: H03H9/02
Filed: 1983-06-28
Abstract: A surface acoustic wave device (10, 12) having a lithium tetraborate single crystal substrate (11, 21) is proposed. An electro-mechanical coupling coefficient K<sup>2</sup> of the substrate is about 1% so as to obtain a surface acoustic wave having sufficient practical energy. When cut angles of the substrate and a propagation direction of the surface acoustic wave are expressed by Eulerian angles (90+λ, 90°, 90°), a thickness t of an electrode (12, 13, 22, 23, 24) formed on the substrate falls within a region bounded by a dotted curve and an alternate long and short dash curve in Figure 8. The dotted curve and the alternate long and short dash curve indicate the experimental relationship between the cut angle λ and the thickness t when the TCD is set at 5 and -5 ppm/°C, respectively. When the film thickness t is set within the above-mentioned range, the absolute value of the TCD is set at 5 ppm/°C or less. When the cut angle is 25°, the TCD of the substrate becomes zero. Therefore, using the substrate having the above cut angle, the TCD becomes zero or almost zero in the electrode region and nonelectrode region of the surface of the substrate.

Abstract: An ink jet printer includes a print head for generating a plurality of groups (88,90, etc, 92,94, etc, and 96,98 etc.) of jet drop streams (50) arranged in a first row in which the jet drop streams in each of the groups are uniformly spaced along the row and interspersed with jet drop streams in each of the other groups. A plurality of charge electrodes (52) are provided with each electrode positioned adjacent one of the jet drop streams. A deflection electrode provides a deflection field through which the jet drop streams pass, whereby drops charged to a catch charge level or a guard charge level are deflected to a catcher. Control means repetitively applies print control signals in sequence to the charge electrodes associated with each group of jet drop streams, while simultaneously applying a guard signal to the remaining charge electrodes. This arrangement results in predictable drop-to-drop and interjet crosstalk which may be compensated by a shift in charge voltage levels.

Abstract: A mould opening and closing mechanism for a plurality of mould portions of a glassware container manufacturing machine. The mechanism comprises fixed rods (26) carrying fixed pistons (30) on each of which a cylinder (32; 54) is slidably mounted. When fluid under pressure is introduced into the cylinder, the cylinder is caused to slide along the rod. The cylinder is connected to a shaft (18, 20, 22, 24) so that movement of the cylinder causes the shaft to turn about its longitudinal axis. The shaft is connected to a mould portion carrier so that, when the shaft turns, the mould portions are moved to open or close them.

Abstract: The leaflet index has key levers 6, of which at least two, normally all of them, are grouped together to form an integral production and assembly unit, specifically by injection moulding or the like from a resilient plastic. The individual key levers 6 are connected to one another by their bending zones 9 to form the integral unit. It is not only possible for the entire set of key levers to be produced economically in one operation, but assembly is also made considerably easier since, in practice, only one action is required to insert all the levers. An additional torsion lever 13 for each key lever is assigned to each bending zone 9 in order reliably to prevent the movement of the one key lever being transmitted to adjacent key levers. <IMAGE>

Abstract: A plug for a horizontal cryostat penetration comprises a plurality of nested housings with thermal insulation disposed between the housings. Each housing has a tubular extension which is heat stationable to portions of the cryostat penetration, the more innerthe housing, the colder being the portion to which it is stationed. The innermost and outermost housings each possess pressure relief means for relieving internal pressure buildup which occurs as a result of magnet quench or vacuum loss. In operation the plug is disposed within the cryostat penetration and in particular, typically within a tubular conduit associated therewith. Thetubular extension ofthe outermost housing also has preferably disposed around its exterior, one or more string-shaped helically disposed lengths of sealing material. Accordingly, when the plug is placed within the penetration, a helical coolant vapor path is formed for plug cooling and exterior ventilation.

Abstract: 57 This relay has an actuator which has a pair of coupled together driving elements, of a type which deflects according to applied voltage. The actuator deflects in one direction when voltage is applied to one driving element and deflects in another direction when voltage is applied to the other driving element. A bistable switching mechanism has an actuating member and a set of contacts. These contacts are flipped over to a first state when the actuating member is impelled in a first direction and thereafter stay stably in the first state until the actuating member is impelled in a second direction, and similarly are flipped over to a second state when the actuating member is impelled in the second direction and stay stably in the second state until the actuating member is impelled in the first direction. A drive circuit upon command supplies a one shot pulse of relatively short duration to either the one or the other of the driving elements. The actuator is coupled to the actuating member of the bistable switching mechanism, so as when deflecting in the one direction to impel the actuating member in the first direction, and when deflecting in the another direction to impel the actuating member in the second direction. Optionally, the coupling between the actuator and the actuating member of the bistable switching mechanism may have a certain amount of play provided in it, and the driving elements of the actuator may be piezoelectric elements.
