Title: Method for pre-coating ion-exchange resin in filter-desalting apparatus
Inventor: ITO TOMOAKI
IPC: C02F1/42
Filed: 1988-02-05
Abstract: PURPOSE:To improve filtration performance and eliminate increase in differential pressure, by introducing slurry having a specific mixing ratio of anion-exchange resin and cation-exchange resin into a filtration column, thereby pre-coating a filtration layer of resins over an element. CONSTITUTION:The resin ratio of cation/anion of ion-exchange resin to be filled into a slurry regulating tank 2 is made to be 5/1 or more, while the concentration of the slurry of resin to be fed to a filtration column 3 is 0.25wt.% or less by admitting the partial return water through a bypass pipe 16. The resin slurry is diffused in the filtration column by means of baffle plates 10, whereby floc (flocculated body) of the ion-exchange resins, following the flow of slurry entraining water, is caused to attach to the surfaces of a number of elements 6 and superposed thereon, forming a filtration layer 7. The slurry entraining water is returned to the slurry regulating tank 1 through the elements 6, outlet pipe 10, return pipe 15, and valve V2.

Title: Helix type travelling-wave tube
Inventor: TSUTAKI KUNIO
IPC: H01J23/26
Filed: 1992-02-12
Abstract: PURPOSE:To improve electron beam efficiency and collector efficiency, and to heighten overall efficiency by providing two velocity tapered portions changing circuit cycles, and changing the circuit cycle at the first velocity taper portion exponentially in an axis direction. CONSTITUTION:An output side slow-wave circuit 8 has an input slow-wave circuit portion 7, which has a larger circuit cycle P1 than an input circuit cycle P0, and a first velocity taper portion, which changes cycles from the cycle P1 to the cycle P2 in order along a direction from an electromagnetic wave attenuator 4 to a electromagnetic wave extracting portion 6. A slow-wave circuit has the circuit cycle P2, a second velocity taper portion changes the cycle from the cycle P2 to a cycle P3 between P1 and P2, and the output slow- wave circuit 8 has the cycle P3. By changing the circuit cycle at the first velocity tapered portion exponentially in an axis direction, an electron beam having little velocity dispersion is formed in the vicinity of the electromagnetic wave extracting portion 6 and radiates into a collector portion 2. Accordingly the collector portion 2 becomes workable at a low electric potential so as to improve collector efficiency.

Abstract: PURPOSE:To improve the power factor of input by resetting the current of a chock coil with every switching, and driving the switching elements with fixed frequency, and controlling the on time according to the change of output voltage. CONSTITUTION:A series circuit, comprising a switching element 4, a choke coil 6, and a switching element 5, is connected between the DC output terminals of a full-wave rectifying circuit 2. By driving circuits 18 and 19, the switching elements 4 and 5 are turned on or turned off at the same time with the fixed frequency enough high than the frequency of AC voltage. The on-time is controlled according to the change of output voltage. The current of the choke coil 6 is reset with every switching. The AC gain of an error amplifier 15 is let down enough with a capacitor 20 and a resistance 21 so that it may not respond to the basic frequency of full-wave rectifying voltage. This way, input current waveform becomes analog to the input voltage waveform.
