The compact wafer carrier has an air cleaning device, including a secondary battery as a power source, a motor fan, and a particulate air filter, and a storing chamber directly connected to the air cleaning device for storing the wafer. The storing chamber has an opening for receiving the filtered air flow, and a second opening for loading and unloading the wafers, both openings facing each other....

Dispensing within a liquid dispensing and suctioning system (14) is controlled by pinching a flexible tube (48) with a spring-biased actuator (58). The system (14) includes a slidable extension (52) for pulling the actuator (58) to open the tube (48) to dispense liquid to a surface to be cleaned. The system is assembled with a tubular wand (16, 18) of a wet/dry suctioning system.

The system includes an electron optical device (1) for generating electron beams and irradiating the beams to a sample on a stage through a number of electron lens, a main deflection coil (6), and subdeflection electrodes (7), to form predetermined circuit patterns on the sample. The system also includes a position control device (10) controlling the driving of the stage based on a stage position ...

In a color cathode ray tube, a single selectron beam is deflected through a deflection yoke and passes through a collimation lens to an active shadow mask formed with a plurality of apertures to divide the beam into a plurality of segments. Each beam segment is intensity modulated at the entrance of its aperture through modulating electrodes which focus the electrons in the beams at crossover poin...

A wobble plate compressor has a slant plate (50) including a boss (54) for mounting a wobble plate (60) and balance weight ring thereon. The balance weight ring prevents the axial movement of the wobble plate during operation of the compressor. The balance weight ring includes a centrally located thin plate region defining a recessed portion, and includes a plurality of holes (503) formed at the t...

Beta-fluoropyridine cpds. are prepd. by contact-reacting alpha- or gamma- halo-substd. beta-halopyridine with KF or CsF in a polar diluting agent to produce beta-fluoropyridine, and adding alpha- or gamma-halo substd. beta halopyridine to the produced beta- fluoropyridine. The diluting agent is pref. dimethylsulphoxide , sulpholane or N-methylpyrrolidinone. +
