  • Patent number: 7369866
    Abstract: Message processing for a communication terminal is disclosed. In one embodiment, a method for preparing an outgoing message includes composing the message, programming control information for performing a word spacing function, and associating the outgoing message with the control information. The control information may preferably assert whether to insert spaces between words of the outgoing message. In another embodiment, a method for processing a message includes receiving an incoming message and incoming control information for performing the word spacing function, and arranging the incoming message based on the incoming control information. An unspaced message may be sent, allowing the sending to include more letters, numbers, symbols, or other ‘non-space characters’ in the message. Furthermore, because the message is sent with the control information, the message may be arranged and displayed in spaced-wording format, allowing for easier reading by the message recipient.

  • Publication number: 20070010688
    Abstract: The present invention provides a method of preparing organic acids from aldehyde compounds by means of liquid phase oxidation which converts an aldehyde group of a compound harboring one or more aldehyde groups into a carboxyl group by using an ionic liquid as a reaction solvent or a reaction catalyst. According to the present invention, the ionic liquid is less volatile even at high temperature and stable against heat, enhancing conversion rate and selectivity and further increasing yield. In addition, the ionic liquid can be easily separated and recycled from the reactant and product.

  • Patent number: 6827950
    Abstract: The present invention relates to Aralia extracts and a therapeutic agent comprising Aralia extracts as an active ingredient. The composition and therapeutic agent according to the present invention are effective in preventing cataract, delaying the development of cataract, and treating cataract. According to the present invention, extracts of Aralia are obtained by extraction with alcohol. Addition of myo-inositol or taurine to the extracts will result in a synergistic effect in the treatment of cataract. In addition, oral administration of beverages, galenicals, and nutraceuticals, which comprise Aralia extracts as an active ingredient, will be effective in prevention, delay and treatment of cataract caused by complications of diabetes. Aralia extracts will have the same effect in the case where they are used as an ophthalmic agent. They can also be used as an eye drop or an eye ointment.

  • Patent number: 4956082
    Abstract: The apparatus comprises a rotor, plurality of spaced transverse ribs disposed along the axis of the rotor and a plurality of longitudinal ribs having the shape of an impeller of a pump, the plurality of longitudinal ribs being mounted on each of said transverse ribs. The plurality of longitudinal ribs and transverse ribs constitute a biological contactor, thereby causing wastewater to be treated by passing through the biological contactor. The longitudinal ribs are obliquely installed in an appropriate angle with the perpendiculars of the exterior tangent arc of the contactor like the impeller of a pump, thereby making wastewater pass efficiently through the space between the ribs with centrifugality by rotation of the rotor.
