Stemming reduces inflected words to their stem or root form.
For example the words fishing, fished,fish, and fisher are reduced to the root word,fish,
so a search for fisher returns all the different variations
Returns only one member of a family of patents

The invention relates to a display system intended to be attached to the head or to a helmet. The system comprises at least an image intensifier unit having an input on which an image can be projected and an output which retransmits the projected image with an enhanced intensity and within at least one predetermined first frequency band. The system further comprises an eyepiece which is composed of a first and second transparent reflecting element having angle- and frequency-dependent reflectance and transmittance properties, said properties, in combination with the said first frequency band, resulting in the intensified image emerging via the eyepiece. The display system is further provided with an image display device which transmits a visible video image in the direction of the eyepiece. The said properties of the eyepiece in combination with the said second frequency band results in the video image emerging via the eyepiece and within at least a predetermined second frequency band, in a direction which is at least virtually identical direction to that of the intensified image.

 Appl.No PCT/US1999/024003 Applicant MITSUBISHI CHEMICAL AMERICA, INC. Inventor DONELLY, John, C.
A method and apparatus for recycling and recovering potentially explosive solvents includes providing a contaminated solvent to a distillation tank (14), vaporizing the solvent in the distillation tank, thereby producing solvent vapor, condensing the solvent vapor in condenser (16), and adding a free radical scavenger substance to the distillation tank during the heating step. The condensed vapor is then collected in a clean solvent tank (18) where additional free radical scavenger substance is added. The contaminated solvent is introduced into the solvent recovery system (10) by providing contaminated solvent into contaminated solvent tank (12) which is connected to the distillation tank, and an oxygen displacer substance is provided to the contaminated solvent tank and the clean solvent tank so as to minimize the amount of free oxygen in the tanks.

A ball forming process is for forming a ball (32) of metal on a metal wire (26) in a wire bonder (20). The process includes generating a glow discharge (11) between an electrode (4) and an end (5) of the metal wire (26) to form a ball (32) of metal at the end (5) and the wire (26). The ball is formed in a gaseous atmosphere comprising greater than 96 % by volume of nitrogen and substantially no hydrogen.

A high efficiency air conditioning apparatus and an air processing system incorporating such an air conditioning apparatus are presented to enable energy conservation by preventing sensible heat as well as latent heat from outdoor air. The air conditioning apparatus comprises a first air passage (A) for directing air from a first space to a second space, and a second air passage (B) for directing air from the second space to the first space. A desiccant device (103) alternatingly communicates with the first air passage and with the second air passage so as to perform a regeneration process in the first air passage and to perform a dehumidification process in the second air passage. A heat pump device (200) has a high temperature heat source (220) for heating air flowing through the first air passage and a low temperature heat source (210) for cooling air flowing through the second air passage. An enthalpy heat exchanger (153) for performing enthalpy heat exchange between air in the first and second air passages.

A share charging method by which a called subscriber is made to share only the telephone charges for the calls from calling subscribers in the charge areas permitted by the called subscriber according to the condition designated by the called subscriber. In this method, charge sharing information of calling subscribers and/or called subscribers is registered in advance in a control station, etc., and the calling and called subscribers share the charges based on the information. Specifically, there are some methods including a base sharing charging method in which when the destination is changed and the charge for the call to the original destination is higher than the call to the changed destination, the caller shares the charge for the path from the caller to the original destination and the called subscriber shares the charge from the original destination to the called subscriber, a selective call charging method in which either of the calling and called subscribers shares the charge based on the contents of the charge sharing information registered in the control station, an MBI value share charging method in which the charge is shared by both subscribers based on the MBI value.

The present invention presents a method and system for controlling usage and protecting against copying of digital multimedia content (such as audio, video, image, and document) and their associated players or readers. The system is arranged so that digital content and their players or readers that are installed in one computer or device cannot be used if they are copied to another computer or device. The system may also be arranged so that duplicated digital content is not usable in the same computer or device. Usage data associated with each item of digital content may restrict the running time during which the content can be used and may be updated automatically after each usage of the content. The content may not be accessible if its permitted usage has expired.

 Appl.No PCT/JP2001/006842 Applicant KURITA WATER INDUSTRIES LTD. Inventor OKUMURA, Masatake
A method for cleaning an ultrapure water supplying system having an ultrapure water producing apparatus connected to a use point for ultrapure water via a flow path, which comprises circulating, for example, a basic aqueous solution within the system, thereby to change the surface electric potential of fine particles present in the system from the polarity different from that of a system element to the same polarity as that of the element and to facilitate removing such particles, and then discharging the particles together with the basic aqueous solution out of the system. The method is excellent in detergency and allows the shortening of the time required for the rinse in order to remove residual components of a cleaning solution.
