Title: Fluid modifying apparatus employing magnetic hydrodynamic theory, magnetic repulsion theory and excitation action due to far infrared rays
Inventor: KANBE TOKUTA
IPC: C02F1/48
Filed: 2000-05-17
Abstract: PROBLEM TO BE SOLVED: To provide a method for rationally utilizing magnetism and far infrared rays. SOLUTION: Flat piping 1 is used as a strong magnetic field forming means in order to reduce the opposed interpole distance between permanent magnets 2 and the cross-sectional area of the piping is reduced at the same time to increase the flow velocity in the piping to enhance magnetic hydrodynamic effect. Magnetic circuits are formed on the rears of the permanent magnets 2 not only to concentrate all of the magnetomotive forces of the permanent magnets to the formation of a magnetic field in the piping but also to prevent the deterioration of the permanent magnets with the elapse of time to semipermanently keep the life thereof. Pole pieces are mounted on the permanent magnets to concentrate magnetic flux to a narrow region to form a magnetic field high in flux density to enhance magnetic hydrodynamic effect.  The periphery of the piping is filled with far infrared emitting ceramics to emit far infrared rays using the circumferential temperature as drive force to reflect the same from the inner surface of a cover and the reflected far infrared rays are concentrated to the piping to supply far infrared energy to a fluid efficiently to excite the motion of the molecules to activate the fluid.

Title: Semiconductor integrated circuit device
Inventor: HATORI FUMITOSHI
IPC: H04L25/02
Filed: 2000-06-29
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit device, that inputs/ outputs data between LSIs with a differential signal and enables reduction in the number of data transmission lines. SOLUTION: Each transmitter TX of a transmitter side LSI 11 and each receiver RX of a receiver side LSI 12 are interconnected via a plurality of data transmission lines L. In this case, one data transmission line L is used in common between adjacent transmitters TXS and between adjacent receivers RXS. Thus, the number of the data transmission lines L is suppressed to be nearly the same number for the transmission of non-differential signal in spite of transmission reception of the data by the differential signal. Moreover, since the integrated circuit can be operated in the transmission of the differential signal at a frequency higher than the transmission of the non-differential signal, the data transmission speed can be improved in the case of transmission of differential and non-differential signals in a conventional integrated circuit.
