Title: Translation mirror based beam steering mechanism with ultrahigh frequency response and high sensitivity
Filed: 2012-09-28
Abstract: A beam steering mechanism with ultrahigh frequency response and high sensitivity includes two mirrors. Beam steering is achieved by the translations of the two mirrors in the X axial mirror group and Y axial mirror group. The two translation mirrors are located at the output of two PZT actuators, and are directly actuated by the two PZT actuators. The dynamic characteristics of the two translation mirrors are always exactly the same as the output characteristics of the PZT actuators. There is no mechanical translation loss in this beam steering mechanism, and so, the beam steering mechanism has an ultrahigh frequency response and high angular deflection sensitivity.

IPC: B29C45/22
Filed: 1983-07-12
Granted: 1987-02-19
Abstract: This invention relates to an improved integral manifold for a sprue gated multi-cavity injection molding system and a method of manufacturing the same. The manifold has an inner body portion which fits into a hollow retaining ring portion to define a circular peripheral space between them. The inner body portion is formed of a corrosion and abrasion resistant material such as stainless steel and has a number of straight melt ducts extending through it from a common inlet to spaced outlets each leading to a central bore in separate heated nozzles. The peripheral space contains an electric heating element surrounded by a highly conductive material such as copper. The manifold is manufactured by assembling the retaining ring portion on the inner body portion with the heating element in the space between them. A filler tube is located on the retaining ring portion in alignment with a filler duct therethrough and all the joints are sealed by brazing the assembly in a vacuum furnace. A copper slug is then inserted into the filler tube and the assembly is again heated in a vacuum furnace to cast the copper into the peripheral space around the heating element. This provides an integral unit with an improved combination of the characteristics of corrosion and abrasion resistance and thermal conductivity, as well as straight melt ducts which facilitate cleaning.

Granted: 1990-02-01
Abstract: in a continuously-variable-ratio transmission of the toroidal ace rolling traction type, each roller is mounted between the opposing disc surfaces in a roller mounting which is displaceable by an hydraulic ram. Each end of the ram has a piston (13 or 14) at the end of the roller mounting sliding in a cylinder (15 or 16).The hydraulic control system has a combined flow divider and pressure control valve (23) which responds to external forces (C1 or C2) from solenoids to shift the roller mounting.Fluid flow in both hydraulic circuits (P, JJ', L' L, R, T and S, MM', K'K, Q, T) is always equalized by the valve (23). Thus displacement of the spools (S1, S2) away from equilibrium, by restricting inlet and outlet ports (R and S or P and Q), raises the pressure in one ram chamber (16 or 15) and displaces the ram. Moreover, the same pressure tends to return the spools to the equilibrium position. Hydraulic stopping of the ram occurs when either ram chamber port (L' or K') is restricted by a piston approaching its extreme position.

Abstract: Line (20) and field (40) deflection circuits generate line and field deflection currents in respective line (LH) and field (Lv) deflection windings to scan a raster on the phosphor screen of a square-planar picture tube having an aspherical faceplate. The asphericity of the faceplate (30) subjects the scanned raster to gullwing distortion. A gullwing distortion correction circuit (70) is responsive to signals repeating at line and field rates, respectively, for modulating the field deflection current during a line deflection period within the field deflection trace interval in a manner that corrects gullwing distortion of a corresponding raster scan line.
