PURPOSE:To produce an optical glass element having high precision at a low cost in a mass, by pressing a glass raw material with a press-forming mold produced by using a material having high heat-resistance and excellent workability as a matrix and having a pressing face coated with a thin layer of a specific alloy. CONSTITUTION:A press-forming mold is produced by using a material having high heat...

Provision is made for varying the size of the pixels or spots printed by an acoustic printer of the type in which one or more droplet ejectors (12) are driven by rf voltage pulses to produce focused acoustic beams (22) for ejecting droplets (25) of ink on demand from a free surface (24) of an ink supply (23). It has been found that the size of the individual droplets (25) of ink that are ejected f...

Sparse arrays (13) of ink droplet ejectors (14) are provided for acoustic printing. The arrays (13) are capable of performing at higher print rates than single ejector printheads because of their parallelism, and they avoid many of the design limitations of ordinary page-width arrays. The increased center-to center spacing of the droplet ejectors (14) in these sparse arrays (13) significantly simp...

The output surface (18) of an acoustic printhead (10) having one or more concave acoustic beam-forming devices for supplying focused acoustic beams (17) to eject droplets (19) of ink (13) on demand from the surface (18) of a pool of ink (13) is planarized by filling those concave devices with a solid material (21) having an acoustic impedance and an acoustic velocity which are intermediate the aco...

In a third-generation computerised tomography apparatus with fan-shaped X-ray beam and a measurement unit consisting of an X-ray source (1) and beam receiver (3) consisting of a series of individual detectors (12), the non-linear partial volume effect is to be substantially eliminated. This effect is caused by the fact that object structures emerge only partially into the finitely thick tomographi...
