Abstract: A brake assembly (10) having a master cylinder (12) attached to the front shell (14) of a power assist apparatus (16). The front shell (14) is connected to a rear shell (20) which in turn is fixed to a stationary member (22). The front shell (14) has a conical section (70) that extends toward and partially surrounds the master cylinder (12). A movable wall (82) located between the front (14) and rear shell (20), which is substantially concentric to the front shell (14), divides the interior thereof into a front chamber (96) and a rear chamber (97). The movable wall (82) is connected to operational pistons (32, 34) within the master cylinder (12). An annular projection (98) extends through an opening (142) in the rear shell (20). A cylindrical member (154) located in the opening (142) extends into the rear chamber (97). A return spring (92) urges the movable wall (82) toward the cylindrical member (154). The position of the cylindrical member (154) is adjustable to align the pistons (32, 34) in the master cylinder (12) and thereby permit fluid communication from a reservoir (38) to the master cylinder (12) through compensator ports (40, 42). A bearing member (150) which surrounds the annular projection (98) has a resilient portion (148) that engages the annular portion (98) to seal the chamber (97) from the surrounding environment. In response to an input signal, a pressure differential is created across the movable wall (82). This pressure differential produces an output force which moves the pistons (32, 34) past the compensator ports (40, 42) to develop an operational fluid pressure for effecting a brake application. The conical section (70) of the first shell (14) reacts to reduce any axial deflection that may be created by the output force.

Abstract: A musical tone signal generator for an electronic musical instrument is constructed by a waveshape generator (13, 14), a function generator (16) and an interpolator (18, 19, 20). The waveshape generator (13, 14) successively generates adjacent two waveshapes of a plurality of different waveshapes which have been intermittently sampled in an actual produced tone. The function generator (16) generates an interpolation function which is a function of time. The interpolator (18, 19, 20) weights the adjacent two waveshapes in accordance with the interpolation function, combines the weighted two waveshapes and outputs the combined waveshape as a musical tone waveshape to be produced at a rate corresponding to a frequency of the musical tone waveshape. In the waveshape generator (13, 14), the generation of next two adjacent waveshapes are performed when a value of the interpolation function has become equal to a predetermined value. As a result, it is made possible to obtain a good quality timewise spectrum change of the musical tone waveshape.

Abstract: A rotary piston vacuum pump is provided with an oil pump in the lubricating oil circuit, a pressure relief vent connected to the pumping chamber from a higher pressure source, and biased valve connected between the oil pump and the oil circuit as well as between the pressure relief vent and the first pumping chamber for controlling the flow of oil and pressure, respectively. The oil pump pressurizes the oil in the oil lubrication circuit as a function of vacuum pump operation. The valve is responsive to the oil pressure created by the oil pump. The valve is actuated to maintain the free flow of oil from the oil pump to the oil circuit when the pump is operating. When the pump is shut-off, the bias of the valve shuts off the flow of oil through the oil circuit and opens the connection between the pressure relief vent and the first pumping chamber to increase the pressure in the latter such that lubricating oil is not drawn into that pumping chamber. This increased pressure from the pressure relief vent actuates an inlet shut-off valve which isolates the first pressure chamber from the operating chamber.

Abstract: in a soil cultivating implement which comprises a row of power-drivable soil working members (3) that extends substantially horizontally perpendicular to the intended direction of operative travel (A) of the implement, means is provided to exert either an upwardly or a downwardly directed force upon that row of soil working members (3) and a hollow frame portion (1) which rotatably supports them. A supporting ground roller (15) lies behind the row of members (3) relative to the direction (A) and the axis of rotation (13) of the roller (15) is contained in an imaginary vertical plane (A-A). A mass in the form of a seed drill (32) or other mobile implement, tool or machine exerts a downward force on the soil cultivating implement at a coupling point (29, 30) and this downward force, in turn, exerts an upward force on the frame portion (1) at the front thereof by way of arms (8, 26) and strong pivots (7) which arms (8, 26) are turnable about the axis of rotation (13) of the ground roller (15). The upwardly directed force assists the soil working members (3) in rising from the ground to ride over a rock or other buried obstacle without significant damage and alternative constructions are described and illustrated in which the point of application of the mass is adjustable to a location in advance of the plane (A-A) so that the force acting on the frame portion (1) and soil working members (3) will be directed downwardly rather than upwardly. This can be of great assistance when heavy soil in a very hard condition is to be cultivated since it facilitates initial penetration of tines (5) of the soil working members (3) into the soil and tends to prevent them from riding upwardly out of the soil as cultivation continues. In one alternative embodiment, the mass is in the form of weights that are adjustably angularly displaceable around the axis of rotation (13) of the ground roller (15) to locations spaced at different distances from that axis (13) and to locations either behind, or in front of, the plane (A-A) relative to the direction (A).

Abstract: A process for joining a first kind of synthetic resin (1, 101) to a second kind of synthetic resin (2) includes several steps. A first step is providing the first kind of synthetic resin (1, 101), which may include fillers (102), e. g., glass fibers. A second step is setting a second contact surface (21) of the second kind of synthetic resin (2) on a first contact surface (11) of the first kind of synthetic resin (1, 101). A third step is exposing an outer surface of the second kind of synthetic resin (2) to a laser beam. The second kind of synthetic resin (2) transmits the laser beam to the first kind of synthetic resin (1, 101 which stores up heat of the laser beam. The second contact surface (21) of the second kind of synthetic resin (2) and the first contact surface (11) of the first kind of synthetic resin (1, 101) are melted by the heat of the laser beam. A plurality of projections and a plurality of recesses are formed on both the first contact surface (11) of the first kind of synthetic resin (1, 101) and the second contact surface (21) of the second kind of synthetic resin (2). A plurality of the projections of the first kind of synthetic resin (1, 101) engage with a plurality of the recesses of the second kind of synthetic resin (2). If fillers (102) are provided, at least some of them (102) will extend between the first and second synthetic resins (1, 101, 2). Accordingly, the second kind of synthetic resin (2) is securely joined to the first kind of synthetic resin (1, 101).

Abstract: The use of silicon-containing polyimide as an oxygen etch barrier in a metal lift-off process and as an oxygen etch stop in the fabrication of multi-layer metal structures is described. In practice, a lift-off layer (12) is applied on a substrate (10), followed by a layer of silicon-containing polyimide (14) and a layer of photoresist (16). The photoresist is lithographically patterned, and the developed image is transferred into the silicon-containing polyimide layer with a reactive ion etch using a CF₄/O₂ gas mixture. The pattern is transferred to the lift-off layer in a reactive ion etch process using oxygen. Subsequent blanket metal evaporation (22) followed by removal of the lift-off stencil results in the desired metal pattern on the substrate. In an alternate embodiment, the silicon-containing polyimide can be doped with a photoactive compound reducing the need for a separate photoresist imaging layer on the top.
