Title: Attenuator switch
Inventor: SHIMODA HIROMI
IPC: H03K17/74
Filed: 1985-07-08
Abstract: PURPOSE:To improve transmission phase characteristics by connecting two diodes in parallel with each other and in opposite polarity and connecting them in series with a ring modulator. CONSTITUTION:The ring modulator RM, the pin diodes D5, D6 connected in parallel with each other and in opposite polarity, resistors R1, R2 and a capacitor C are provided. The pin diodes for reverse bias in the ring modulator RM are regarded as a capacitive impedance connected in parallel with the transmission line. On the other hand, since a diode biased reversely in the pin diodes D5, D6 is regarded as a capacitive impedance connected in series with the transmission line, the transmission phase characteristic by the series capacitive impedance compensates the deterioration of the transmission phase characteristic by the parallel capacitive impedance of the ring modulator RM. Thus, the transmission phase characteristic is improved.

Title: Device for executing physical and/or chemical treatment and method of operating said device
Inventor: DEITSUKU GERITO KURAREN
IPC: B01J8/24
Filed: 1984-07-21
Abstract: This invention relates to apparatus for carrying out physical and/or chemical processes, more specifically a heat exchanger (10) of the continuous type, comprising a large number of vertical heat exchanger tubes (18) mounted between a lower chamber (17) and an upper chamber (16) within a jacket (15). Within the tubes (18) small solid particles are kept in a fluidized condition by the fluid medium passing up from the lower chamber (17) through the tubes (18), so as to achieve a good heat transfer, whereas also any deposit will be removed from the innertube walls. Forthe downward flow of the granular mass at least one return tube (21) is provided. Downward circulation of the fluid medium through the return tube (21) should be minimal, however, which can be achieved by an increase of the pressure difference between the upper and lower chamber (16; 17), which increase of the pressure difference can be achieved by fitting several distribution plates (24; 42) at a level above the return tube (21) outlet into the lower chamber (17), preferably so thatthe apertures in the various distribution plates (24; 42) of the multiple design are not vertically in line.The second distribution plate (42) also serves to minimise excessive wear of the material of the jacket (15) due to the eddying motion of the granules.
