Title: Apparatus for inspecting leakage around engine combustion chamber
Inventor: OKADA HIROSAKU
IPC: G01M3/02
Filed: 1988-07-28
Abstract: PURPOSE:To easily inspect the surface injury of a grommet contact part by mounting a leak tester for bringing not only a hard seal member into contact with the periphery of a combustion chamber being an object to be measured under pressure but also a soft seal member into contact with a water hole and the outer edge of a connection surface under pressure and changing over low pressure air and high pressure air. CONSTITUTION:Low pressure air is supplied to the part, which corresponds to a combustion chamber, inside a hard seal member 28 from an air supply port 33 and the air leaked to the outside corresponding to surface injury from said member 28 is guided to an air flow tester from a low pressure air lead-out port 34 to measure the flow rate of the leaked air and the surface injury of the grommet contact part of a cylinder head 2 is detected. Continuously, the line to the supply port is changed over from a low pressure line to a high pressure line and high pressure air is sent to the interior of the member 28 under pressure from the supply port 33. The member 28 is low in sealability to said high pressure air and the high pressure air flows to the outside from the contact part with the head 2 and the whole of the inside of an outer edge soft seal member 30 becomes a high pressure state. Then, the leakage to a cooling water passage due to the structural flaw of the leakage of a valve seat 31 in the high pressure state is detected by a pressure switch or an air flow tester.

Title: Minute electrode for electrochemical analysis
Inventor: MORITA KENICHI
IPC: G01N27/403
Filed: 1988-07-28
Abstract: PURPOSE:To enable the measurement of the exact concentration of oxygen while enabling the measurement of a flow speed simultaneously, by a construction wherein one opening end of a molded matter formed of a non-conductive substance and provided with two or more minute holes different in length is fixed on the surface of an electrode. CONSTITUTION:In a minute electrode, a plurality of carbon fibers 1 are covered with a non-conductive substance 2 so as to form a bundle of carbon fibers. The upper ends of the carbon fibers are recessed from the upper end of the non-conductive substance 2 to form two or more piercing minute holes 3, 3' opened outside, and the minute holes are different in length between the group of 3 and that of 3'. When the aforesaid electrode is combined with a reference electrode to be used as a current- oxygen meter, a current value in a steady state is expressed by a formula I, since an oxygen-reducing reaction in a water solution is dominated by diffusion. In the electrode, the length of the whole diffused layer is the sum of the length of the minute hole 3 and the thickness of a diffused layer 5 produced on the upper end of the non- conductive substance 2. The thickness of the diffused layer 5 is determined when a flow speed is determined and has no relation with the concentration of oxygen. In addition, there is no effect of a diffusion constant D.

Title: Floor structure
Inventor: SANO AKIHIKO
IPC: E04B5/02
Filed: 1994-08-11
Abstract: PURPOSE:To enhance workability and maintain fire resistance for a long period by installing a groove to the upper area of joints of opposed panels when constituting a floor with a cement-made panel and compressively filling up a fixedly formed elastic refractory material into the groove. CONSTITUTION:A groove 3a, which is opened upward, is installed to a joint of a cement-made panel, such as an ALC board where a fixedly formed refractory material made of an elastic material which is high in heat resisting temperature and small in thermal conductivity, is compressively filled up into the groove 3a. The groove 3a may be shaped up like a trapezoid, a triangle and a pentagon in addition to a square. The work may proceed to a next process without having a curing period. Even when the panel is subjected to deformation produced by vibration or load, the filled refractory material is designed to follow joint deviation or opening and maintain fire resistant properties for a long period. This construction makes it possible to fill up a refractory material unitedly from the upper surface after the panel has been placed and prevent the refractory mate rial or the like from dropping from a gap.
