An apparatus and a method for off-line pre-conditioning a conditioning disc that is used in a chemical mechanical polishing process are provided. In the apparatus, an upper platform for mounting a conditioning disc thereto and a lower platform for mounting a polishing pad thereto are engaged together under a pre-set pressure and rotated in opposite directions for a pre-set length of time. The apparatus is effective in removing loose particles from the surface of the conditioning disc such that t...

A multi-stage water conditioning system is structured for conditioning a flow of influent water passing through the conditioning system by removing one or more cations including sodium, iron, barium, and or ammonia from the influent water, while also possibly adding (as required) calcium and magnesium. Such a conditioning of the influent water results in a reduction in the sodium adsorption ration (SAR) and electrical conductance (EC) of the influent. Versions of the water conditioning system ma...

An air conditioning system to treat a latent heat load and a sensible heat load in a room includes a plurality of utilization units, a heat source unit, and connection pipes that connect between the units. The utilization units include adsorbent heat exchangers provided with an adsorbent on the surface of each. The utilization units are configured to alternate between an adsorption process and a regeneration process. The heat source unit includes a compression mechanism and an accumulator.

Refrigeration/air conditioning equipment includes a first internal heat exchanger for exchanging heat between a refrigerant to be sucked in a compressor and a high-pressure liquid refrigerant, an injection circuit for evaporating a bypassed high-pressure liquid at intermediate pressure and injecting the vaporized refrigerant into the compressor, a second internal heat exchanger for exchanging heat between the high-pressure liquid refrigerant and the refrigerant to be injected, and a heat source ...

An autonomously-cleaned conditioning system conducts a routine purge cycle to clear accumulated particulates from a filter, concentrator, or both. The purge cycle is conducted by reversing air flow through the filter and/or concentrator. Air flow is reversed on a periodic basis or on the occurrence of a condition, such as a reduction in air flow exiting the concentrator.

Implementations of the present invention include systems, methods, and apparatus for improving the fuel efficiency (mpg/kpl) of a motor vehicle during those times when the vehicle air conditioning system is operating. Whenever the driver takes his foot off the gas, or the vehicle engine is otherwise caused to decelerate, the refrigerant compressor clutch engages, allowing the compressor to operate on previously-imparted vehicle waste energy (e.g., imparted by the engine, or by downhill travel.) ...

The invention relates to a continuous method for pressure-conditioning material for food and/or semi-luxury consumables, wherein said material (12) is introduced through an entrance (4) into a hyperbarically pressurized conditioning chamber (2), where it is treated with a conditioning agent, and extracted again from said conditioning chamber (2) at an exit (8), wherein the material (12) is conveyed continuously from said entrance (4) to said exit (8) in a conditioning chamber (2) inclined obliqu...

A sensor signal conditioning circuit and sensor system incorporating the same. In one embodiment, the signal conditioning circuit includes a DC-coupled detector that converts a sensor signal into a discrete level signal. An AC-coupled detector having a dynamic DC threshold input also converts the sensor signal into a discrete level signal and has a startup delay associated with the dynamic DC threshold input. The signal conditioning circuit further includes a device that inhibits the DC-coupled ...

In a unit case of a vehicle air conditioning apparatus, air mix chamber is not provided. Cooled air cooled by an evaporator and heated air heated by a heater core are directly introduced to a face opening and a foot opening of the case and then mixed in a face duct and a foot duct. The case has a guide for directing a flow of the heated air or the cooled air. The guide, the foot opening and the face opening are arranged such that the amount of heated air passing through the foot opening is large...

A physical conditioning device for golfers is provided. A weight is attached to the tip of a standard golf club shaft to provide strength training for a the backswing portion of a golf swing. A drag chute is attached to the shaft to add resistance to the downswing of the golf swing to prevent the user from simply allowing the weight of the club to cause the club to drop with little physical effort. This combination of weight and drag chute provides an enhanced conditioning effect.
