Title: Dissolved hydrogen peroxide sensor
Inventor: SUGANO KENICHI
IPC: G01N27/414
Filed: 1986-07-03
Abstract: PURPOSE:To enable measurement of the concentration of dissolved H2O2, by providing a conductor layer on the surface of a gate section of an IGFET. CONSTITUTION:This sensor includes at least a conductor layer 7 provided on the top of a gate section of an IGFET, an electrolytic layer 8 containing an Fe (II) complex provided on the top of the layer 7 and a reference electrode provided in the layer 8. As the layer 8 gets in contact with a liquid to be measured, hydrogen peroxide in a solution to be measured infiltrates the layer 8. The hydrogen peroxide entered into the layer 8 oxidizes the Fe (II) complex in the layer 8 to be turned to an oxidation body. As a result, the concentration ratio between the reduction body and the oxidation body of the Fe complex varies to changes a potential of the layer 7 provided at the gate section 2. The resulting changes in the potential are outputted as drain current to measure the concentration of dissolved oxygen. Here, to keep the potential of the solution at a specified level with respect to a source 3, that is, to keep a gate voltage within a measurable range, a bias electrode is applied through a reference electrode.

Title: Spray nozzle
Inventor: WATANABE MASARU
IPC: B05B1/26
Filed: 1979-11-30
Abstract: PURPOSE: To prevent the back flow of sludge liquid and the clogging of injection port owing to sludge deposit even if the nozzle is dipped in the sludge liquid by providing a nozzle tip which closes the injection port from the outside to the outer side of the nozzle body.  
     CONSTITUTION: While the spray is not operating, an operating lever 14 is held energized inward of the nozzle body by the elastic force of a compression coil spring 21, and a nozzle tip 15 closely contacts the beveled part of an injection port 4, thereby preventing sludge liquid from entering the nozzle body 1 inside. When the spray is operating, spray liquid is fed into the nozzle body 11, passes the flow holes 20, 20 opened in the spring bracket and the clearance between the inside surface of an increased diameter pocket part 18 and the outside circumferential part of a spring bracket 17, flows into the nozzle cap 13 and pushes this outward against the elastic force of the spring 21, thereby moving the nozzle tip 15 outward. This causes the spray liquid to scatter from the clearance between the injection port 4 and the tip 15, thus even if sludge sticks in this clearance, it is washed off.

Title: Cooling device for metallic plate
Inventor: HINO YOSHIMICHI
IPC: B21B45/02
Filed: 1995-06-22
Abstract: PURPOSE: To realize the uniform dispersion state of waterdrops, and to facilitate a cooling control by providing mechanisms making positions in the horizontal direction of guide plates and positions in the vertical direction of transmission type dispersion plates variable. CONSTITUTION: The flow of cooling water is supplied from headers 7 to pipe- shaped nozzles 6, a laminer flow 12 is formed, thereafter, the flow of the cooling water is deflected by guide plates 4, and is changed to a water-film shaped flow. The flow of the cooling water supplied on transmission type dispersion plates 1 and transmitted, becomes waterdrops 9 to drop on a metallic plate 10. Since the transmission type dispersion plates 1 are vertically adjustably composed by height adjustment mechanisms 3, when positioning the transmission type dispersion plates 1 at the uperside, a comparatively large cooling power being a cooling power lower than that of the lamina flow can be attained. At that time, positions in the horizontal direction of the guide plates 4 are adjusted by the expansions and the contractions of width adjustment mechanisms 5. However, for making the cooling water 8 drop without interfering between the cooling water 8 opposing each other, it is necessary to reduce projection quantities of the guide plates 4.
