Abstract: A unitized valve body for use in an automatic transmission includes a plurality of valve bores and a plurality of hydraulic passages. Each valve bore is configured to receive a valve. The plurality of hydraulic passages are in fluid communication with the valve bores. The plurality of valve bores are arranged above and below the hydraulic passages.

Abstract: A unitized valve body for use in an automatic transmission includes a plurality of first hydraulic passages, a second hydraulic passage and a plurality of orifices. The second hydraulic passage extending through the unitized valve body and configured to be in fluid communication with a plurality of valve bores. Each orifice disposed within the unitized valve body and fluidly connecting the second hydraulic passage to a respective first hydraulic passage of the plurality of first hydraulic passages.

Abstract: A unitized valve body for use in an automatic transmission includes a valve bore and an annulus. The valve bore is configured to receive a valve. The annulus is in fluid communication with the valve bore. The annulus defines an outer portion having an outer diameter and an innermost portion located at an interface between the valve bore and the valve. The outer portion having a first axial length and the innermost portion having a second axial length. The first axial length is greater than the second axial length.

Abstract: A bumper for a pendulum that cannot inadvertently become loose is disclosed. The pendulum has at least one and preferably a pair of spaced apart, elongated bumpers. The elongated bumpers generally have an L-shape. The pendulum is comprised of two halves. L-shaped channels are formed in each pendulum half. The bumpers are fitted into channels of the same shape formed in the pendulum halves. When the two halves are fitted together, the L-shaped bumper is captured therebetween. Each pendulum half includes an elevated central area and a pair of recessed areas with each recessed area formed on one side of the elevated area. Side walls are formed at the intersections of the elevated area and the recessed areas. A base wall is formed along the lower edge of the elevated area. The bumper ends extend from the elevated area beyond the side walls and base wall.

Abstract: A pendulum crankshaft assembly for an internal combustion engine includes a pendulum carrier, a pendulum and rolling pins. The carrier and the pendulum have kidney-shaped rolling pin tracks. The rolling pin tracks are kidney-shaped and thus are defined by opposed curved side walls and opposed end walls. The pendulum carrier has an ear extending therefrom to which the pendulum is attached. The pendulum comprises a first half and a second half, each half being positioned on the sides of the ear. At any given time in operation, the gap between the rolling pin and the opposed walls of the rolling pin tracks is never greater than 0.5 mm. The pendulum carrier is attached to a cheek of the crankshaft by a pair of opposed fasteners.

Abstract: An optical blue parametric generation relies upon a nonlinear optical cryl of lithium borate (LiB.sub.3 O.sub.5) properly oriented to generate blue light when appropriately located in a resonant optical cavity and pumped with high intensity light at 355 nm. Beam walk-off and beam pump divergence are greatly reduced due to a specific orientation of non-critical phase-matching so that the 355 nm pump source provides for a sufficient phase-match for output generation near the H Beta Fraunhofer wavelength at 486 nm and also provides for a temperature tuning of the lithium borate crystal to permit exact coincidence to a particular output wavelength so that optical parametric generation from 470 to 487 nm may be assured by the appropriately tuned lithium borate crystal.

Abstract: A solid state laser rod of an anisotropic material is more efficiently side pumped by using cylindrical lenses and a half-wave plate with linear laser diode arrays disposed along the length of the solid state laser rod such that the polarization of the diode array light is rotated to achieve a maximum absorption coefficient in the laser rod material. In addition, Fresnel reflection losses at the lens and laser rod surfaces are reduced by a 90.degree. polarization rotation.
