Title: Waste gas processing device
Inventor: KONDOU JIYUNICHI
IPC: B01D50/00
Filed: 1981-05-25
Abstract: PURPOSE:To avoid to narrow a horizontal inflow passageway by a method wherein a partitioning plate is provided in a gas cooling flow passageway to divide it into two divisions and induce a whirling stream in the waste gas flowed into the cooling flow passageway, and thus the formation of eddies at the curved part of the connecting section is eliminated. CONSTITUTION:The cooling flow passageway 2 is divided into two divisions symmetrically by providing the partitioning plate 6 at the connecting section between the horizontal inflow passageway 1 for the waste gas and the gas cooling flow passageway 2. Subsequently, curved plates 8 and a curved plates cover 9, having a predetermined radius of curvature, are provided between the partitioning plate 6 and the cooling flow passageway 2. The waste gas 7, introduced into the horizontal inflow passageway 1, is introduced into the cooling flow passageway 2 by being divided by the partitioning plate 6 at the communicating section with the cooling flow passageway 2, and the whirling streams, whirling into opposing directions each other are induced by the partitioning plate 6. These whirling streams 10 are ascended through the cooling flow passageway 2 by the centrifugal actions of themselves, therefore, they will never generate eddies at the curved part of the connecting section and, accordingly, will never narrow the horizontal inflow passageway 1.

Title: Power supply switching circuit
Inventor: SAGAWA SHUICHI
IPC: H03K17/08
Filed: 1986-04-04
Abstract: PURPOSE:To omit an external protection circuit for output short circuit in order to simplify the constitution of a power supply switching circuit together with improvement of the maintenance properties, by connecting an output to a control input transistor via a diode and then feeding back the output only in a short circuit state. CONSTITUTION:When the ontput ON/OFF information is set at a high level, a diode D11 conducts to turn on a control transistor (TR)Q11. Thus a main TRQ10 is saturated and the voltage applied to a load LD10 is defined as Vb = Va-VsatQ10 (VsatQ10: collector-emitter saturated voltage of TRQ10). If a short circuit of earth occurs owing to a trouble of the load LD10, the base potential of the TRQ11 is set at about 0V. Thus the TRQ11 is cut off and therefore the TRQ11 is also forcibly cut off. As a result, a power supply V10 to be controlled and the TRQ10 are protected.
