Title: Gas flow rate control apparatus
Inventor: KOJIMA TADASHI
IPC: F16K31/12
Filed: 1980-11-21
Abstract: PURPOSE: To enable an on-off valve and a proportional valve to control with single actuator by controlling the proportional valve only when the on-off valve is to be detected by a switch means whether it is open or not.  
     CONSTITUTION: On a lever 18 supporting a valve body 14, a plate-like operation member 34 is mounted. The operation member 34 is at the place in which it confronts with a switch 48 supported by a casing 1. The relationship between the operation member 34 and the switch 48 is selected so as not to contact when the valve body 14 is closed and to contact when it is open to the predetermined degree to on or off the switch 48. Consequently the on-off valve and the proportional valve arranged in series within the gas passage can be controlled with singla actuator.

IPC: G01L7/00
Filed: 1979-12-21
Abstract: PURPOSE: To measure the gas pressure in a furnace accurately with good responsiveness by providing a partition wall into a lance body to form a gas containing part and a cooling cavity part, and providing a pressure detector within the cooling cavity part communicatably with the atmosphere of the gas containing part.  
     CONSTITUTION: An N 2  gas is introduced into the cooling cavity part 7 of a lance 1 through an N 2  pipe 10 by opening a valve 11 and is exhausted through an exhaust port 12. While the lance 1 is being cooled in this manner, it is horizontally inserted into the charging material layer in a blast furnace. When it reaches a predetermined position, the insertion is stopped and the lance is retreated. A cover body 2 is removed from the end of the lance 1. Further, the lance is retreated to the measuring position. The in-furnace gas is flowed through a lead-in port 15 into the gas containing part 4. The gas pressure is measured with the pressure detecting element 3 projecting from a partition wall 5, and this measured signal is conducted to a display device 9 outside the furnace via a lead wire 6, thus the measured gas pressure is displayed in a display device 9. Since the lance 1 is inserted horizontally, it turns out that the pressure indicates static pressure.

Title: Water level sensing device
Inventor: FUJII SHINJI
IPC: G05D9/00
Filed: 1992-06-24
Abstract: PURPOSE:To provide a compact construction and improve accuracy by disposing a photo-electric sensor having a light emitting element and a light receiving element on the same surface and a prism oppositely to each other to transmit a light signal to the light receiving element by reflecting the light signal only when the prism is on a level with the surface of water. CONSTITUTION:In the case that the amount of the water stored in a hot water tank is small and hence the water level is positioned at the lower part of a water level sensing element 1, a photo-electric signal emitted from a light emitting element 5 of a photo-electric sensor 7 is reflected by an inclined surface of a prism 8 and received by a light receiving element 6. When the water level rises and the prism 8 is submerged, the photo-electric signal emitted from the element 5 is refracted at the lower side inclined surface and dispersed to the outside of the prism, so that the element 6 does not receive the signal. And when the signal is received, a water feed valve and a pump are actuated through a control unit to feed water to the hot water tank. And when the tank has been fully filled with water and the signal is no longer received, the valve and pumps are stopped. As a result, the construction of the device can be made simpler and smaller and it can be inserted into the tank from above and there is no contact point and hence sensing can be made with high accuracy.
