Title: High-frequency amplifier and radio communication system using the same
Inventor: KOBAYASHI KAZUHIKO
IPC: H04B1/04
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To take into consideration the power capacity of a superconducting film, to operate with high efficiency and to secure linearity by a band rejection filter having a first line to which a high frequency signal is supplied and which is formed by superconducting material and a second line for a resonator which is formed by the superconducting material and resonates with respect to an adjacent frequency. SOLUTION: A high-frequency signal RF1 of a desired frequency band f0 is generated by a transmission circuit 1 of, for example, a WCDMA of a radio communication system and is supplied to a power amplifier PA. The power amplifier PA power amplifies the high frequency input signal RF1 and outputs a high-frequency output signal RF2. Since the power amplifier PA has a nonlinear feature which saturates for a high input power, the amplified high-frequency output signal RF2 has a spectrum, which spreads reaching adjacent bands (f1) and (f2) of a communciation band (f0). The high-frequency output signal RF2 is supplied to a superconducting band rejection filter 30 in a refrigerator 40.

Abstract: PURPOSE:To take out a timing signal of a 1/2m period a 1/2n period in particular m, n: positive integers, from the cascade connection of inverters of odd- number steps, with high accuracy. CONSTITUTION:In inverters U1 to UN of each step, the output signal of the logical level which is reverse to the input signal supplied to the gate electrode of an MOS transistor is obtained and a phase inversion is performed. In a switch circuit US, the circuit operation which is similar to an NOR circuit is performed. Therefore, the both of the output nodes F and H of an inverter UN 2 two steps before the final step and an inverter UN of the final step become a low logical level Lo, a switch output node S becomes a high logical level Hi. When the output node F of the inverter VN 2 two steps before the final step becomes a high logical level Hi, the switch output node S becomes a low logical level Lo. As a result, the phase on the output side feebacked to the input side of the cascade connection of the inverter of even-number steps becomes the same as the phase on the output side in the cascade connection of a conventional odd-number steps, and the oscillation condition of a ring oscillator is satisfied.

Title: Electrokinetic separation method and apparatus utilizing surface of moving charged colloidal particle
Inventor: BARII ERU KAAGAA
IPC: B01D61/42
Filed: 1988-03-24
Abstract: An electrokinetic method for separating molecular species employs the surface of moving charged colloidal particles in a buffered dispersing medium, in a process which combines electrophoresis and a variant of chromatography in which the "stationary phase" surface moves. The colloidal particles have on their surface a material having the ability to interact selectively with the molecular species to be separated. The surface of the particles as originally formed may have such an ability, or the surface is modified to produce it. In one embodiment the colloidal particles are negatively charged and the surface-modifying materials are metal ions. In another embodiment the surface of the colloidal particles is modified by the incorporation of affinity groups. The analytes distribute themselves between the dispersing medium and the surface of the colloidal particles, resulting in analyte migration rates which are functions of the individual distribution equilibrium constants and the rate of colloidal particle migration. A capillary column for conducting the method includes surface-modified charged colloidal particles in a buffered dispersing medium.
