IPC: H04L27/04
Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To provide a simple and high-speed modulator by operating a variable attenuator using the circuit element of a field effect transistor(FET) and the like in a control circuit. SOLUTION: A carrier is inputted from a carrier input terminal 10 and a modulation signal inputted from a modulation signal input terminal is converted into control signals 15 and 16 being differential signals which are level-shifted in the control circuit. The attenuation of the variable attenuator 1 is controlled by the control signals 15 and 16 and the carrier is directly amplitude-shift-keying(ASK)-modulated. A modulated wave is outputted from a modulated wave output terminal 20. Voltage between the gate/source of FET constituting the variable attenuator 1 is changed by the control signals 15 and 16 and the carrier is modulated. Attenuation quantity is linearly changed against the control signals 15 and 16 and linear modulation is realized.  When the modulation signal is band-restricted in a base band and a spectrum is settled within regulated occupied band width, radiation out of an occupied band is suppressed to regulated one and below unless it satisfies the condition of linear modulation.

Title: Method for finely pulverizing particles
Inventor: IWATA HIROYUKI
IPC: B02C17/00
Filed: 1987-10-21
Abstract: PURPOSE: To efficiently finely grind powder and granular materials by using a material which is gas at and under ordinary temp. and atm. pressure but turns liquid under a specific temp. and pressure as a medium liquid and making operation near the critical point of the medium liquid at the time of pulverizing the powder and granular material by a ball mill or the like. CONSTITUTION: A ball mill the pulverizing vessel which is constructed as a pressure resistant structure is selected as a pulverizing machine. The feed to be pulverizing and balls are charged therein. The material which is gas at and under ordinary temp. and atm. pressure but turns liquid under the specific temp. and pressure, for example, liquid carbon dioxide, is forcibly fed as the medium liquid into the mill by a high-pressure pump. The operation of the pulverizing machine is started in the liquid state. The grain size is made finer and the viscosity of the medium liquid is increased upon progression of the pulverization and simultaneously the temp. in the mill is elevated by the heat generation accompanying ball motion. When the temp. exceeds the critical temp. (31 deg.C in the case of carbon dioxide), the supercritical state is attained.  Even if the density of the medium liquid exhibits the value approximate to the density of the liquid, the viscosity thereof is about 1/100 and, consequently, the effect of lowering the pulverization threshold grain size is obtd. If the pressure is released after the execution of the pulverization for a specified time, the medium liquid evaporates and the dried materials are easily obtd.
