Abstract: An apparatus for chemical mechanical polishing includes a rotatable platen having a surface to support a polishing pad, a carrier head to hold a substrate in contact with the polishing pad, and a polishing liquid distribution system. The polishing liquid distribution system includes a dispenser positioned to deliver a polishing liquid to a portion of a polishing surface of the polishing pad, and a curved barrier positioned after the dispenser to spread fresh polishing liquid from the dispenser.

Abstract: The invention relates to a swivel adapter-coupler that is to be positioned between a conventional fixed drop elbow on the end of a hose of a tanker truck for an underground storage tank. The other end of the swivel adapter-coupler attaches to the pipe adapter (either the fill pipe or the vapor pipe) of the underground storage tank, in the conventional quick-connect type connection. The swivel adapter-coupler permits loops and kinks in the hose to be removed by rotating the swivel adapter-coupler in the proper direction. Likewise, the invention relates to a rotatable drop elbow to replace the conventional fixed drop elbow at the end of a hose on a tanker truck. The rotatable drop elbow eliminates loops and kinks in the hose by merely rotating the drop elbow in the proper direction.

Abstract: In a horizontal deflection and EHT generator circuit, the supply line is connected directly to one end of the primary winding of the EHT transformer through a series switching element, and a unidirectional element connects that end of the primary winding to the supply line to enable energy recovery to the supply line through the unidirectional element during and following retrace.

Abstract: A horizontal deflection stage for a raster scan device (e.g. a television receiver or a monitor) comprises a deflection generator, a d.c. supply regulator for the deflection generator, a voltage controlled oscillator providing drive pulses to the deflection generator, a phase detecting circuit for locking the oscillator to applied horizontal synchronizing pulses, and a sweep circuit for sweeping the oscillator through a range of frequencies until it achieves phase and frequency lock with the applied horizontal synchronizing pulses. An input to the regulator serves to control the output voltage of the regulator in accordance with the frequency to which the oscillator is locked. Thus the horizontal deflection stage automatically adjusts the horizontal timebase, and the regulated voltage supply of the deflection generator, in accordance with the frequency of the applied horizontal synchronizing pulses, without any operator adjustment being required.
