Patent DE-19944911-A1 (DE)
Title: Waveform generator for producing arbitrary waveforms used in testing semiconductor devices uses an input terminal coupled to a delay unit, a processor and a composition unit
Inventor: YASUO FURUKAWA
IPC: G01R31/28
Filed: 1999-09-10
Abstract: The waveform generator consists of an input terminal (28) coupled to a delay unit (23), a processing unit (25) and a composing unit (21). The delay unit uses a set of delay elements (30-314) to delay propagation of the input signal from the terminal to the processor. The delayed signal is then processed using programmable elements (40b-415b) to produce an output signal. The composing unit then composes these output signals to generate a waveform. An Independent claim is included for a semiconductor testing device.
Patent DE-19950809-A1 (DE)
Title: Transfer of large numbers of small volumes of a fluid to holding vessels comprises displacing fluid in reservoir hole to form projecting meniscus for transfer by contact to vessel
Inventor: FISHER WILLIAM D
IPC: B01L3/02
Filed: 1999-10-21
Abstract: To transfer a fluid, contained in a number of holes (14) in a given format to at least one vessel (110), the fluid in each hole is displaced so that a convex meniscus (106) bulges out of the opening (15). The bulging meniscus and the vessel make contact with each other, for at least a part of the fluid (100) to be drawn into the vessel.  A number of vessels (110) are arranged in the same format as the holes (14) containing the fluid (100). For fluid displacement, a wall (19) of each hole is distorted inwards, through an external pressure on it, which transmits pressure to the fluid against its outer surface. The fluid can also be displaced in each hole by the injection of a displacement fluid, preferably a gas, through a ventilation opening in part of the wall away from the opening of the hole. The injection opening is covered by a membrane, which is permeable to the displacement fluid. An Independent claim is included for an apparatus with a carrier (12) for the holes arranged in a suitable format. A vessel to take the transferred fluid is in a format which matches the reservoir holes. A displacement system (108) forces the contained fluid in the holes towards their openings (15). A system brings the transfer vessel and the hole opening close together. Preferred Features: The transfer vessels are in a flat component, with their openings in a flat format, as a jet printer head with print jet openings (112) for each vessel. An elastic film (18) covers the bottom ends of the holes which store the fluid, over the under surface (13) of the carrier block, or a plastics film covers the upper surface as the holes. The distorting and rigid walls are of a single material piece, as are the holes and the carrier.

Abstract: A belt for a continuously variable transmission is provided, which is
comprised of metal ring assemblies (31) each having a plurality of endless metal rings
laminated one on another, and a plurality of metal elements (32) each having ring slots (35)
into which the metal ring assemblies are fitted, and the belt is wound around a
drive pulley and a driven pulley to transmit a driving force between the pulleys.
When the belt leaves the driven pulley, the metal element (32) falls forward in the
direction of advancement with respect to the metal ring assembly (31). For this reason,
a rear end of a saddle surface (44) of the ring slot (35) in the direction of advancement is
brought into strong abutment against an inner circumferential surface of the metal
ring assembly (31) to produce a concentrated stress, thereby shortening the life of the
metal ring assembly (31). In order to prevent this, the radius of curvature of the rear
end of the saddle surface (44) in the direction of advancement is larger, than that of its
front end to reduce the concentrated stress. When the metal (32) element is formed by
a fine blanking process, the radius of curvature of the rear end of the saddle
surface (44) in the direction of advancement is automatically increased by a punching
shear drop.
