Abstract: A cup assembly structure includes a cup which is composed of a body, a panel, a fixing device, and a snap ring. Through a plurality of projection members, a latching piece, and a groove on the body to be fitted and connected with a plurality of concaved holes, an extension end, and a bending end located on the fixing device, and then through a plurality of protrusions on the snap ring to be fixed with a plurality of slideways of the body, the panel which is located at an exterior of the body can be firmly assembled, and the panel of different pattern can be exchanged, so as to increase a visual effect of using the cup.

Abstract: A text-to-speech conversion system that includes a first module to convert text into words, a second module to convert words into phonemes, a third module to map phonemes to sound units, and a storage unit to store speech representations for a library of sound units. The first, second, and third modules and the storage unit are implemented within a single integrated circuit to reduce size and cost. The system typically further includes a ROM to store the codes for the modules, a RAM to store the text and intermediate results, a processor to execute the codes for the modules, a control module to direct the operation of the first, second, and third modules. The storage unit may be implemented with a multi-level, non-volatile analog storage array and may be programmed with a new library of speech representations by a programming module.

Abstract: A trash can structure is disclosed including a cubic can body frame on which a gabble-shaped cap frame is releasably mounted. The cap frame includes a gabble-shaped door frame swingably mounted thereon. Each of the body frame, cap frame and door frame has removably attached thereto a cover sheet with desired decorative patterns printed or otherwise formed thereon. The body frame includes a rectangular bottom plate on which four upright bars are releasably mounted with four horizontal bars extending between the upper ends of the upright bars to form the cubic structure. The cap frame and the door frame are constituted by a pair of opposite and spaced triangular side frames connected by three horizontal bar. The door frame is smaller in size than the cap frame and is swingably hung on the upper one of the three horizontal bars of the cap frame so as to cover the access opening formed on the cap member.
