Title: Under-floor storing device
Inventor: MATSUSHIMA RYOICHI
IPC: E04F19/08
Filed: 1996-06-25
Abstract: PROBLEM TO BE SOLVED: To enable both a heat insulating effect and a convenience in use to be satisfied concurrently by a method wherein an inner lid having a thermal insulating characteristic is arranged between a main body of the storing device and an outer lid and the inner lid is formed into a substantial pyramid shape as viewed from a side surface. SOLUTION: An inner lid 5 having a thermal insulating characteristic is arranged between a main body 2 of a storing device and an outer lid 4 for opening or closing the main body 2 of the storing device and the inner lid 5 is formed into a substantial pyramid shape as viewed from a side surface. One of either an upper edge 5a or a lower edge 5b of the inner lid 5 is resiliently contacted with an inner circumferential surface 2a of the main body 2 of the storing device. With such an arrangement as above, when the inner lid 5 is opened or closed, since a contact area between the inner lid 5 formed into a substantial pyramid shape as viewed from the side surface and the inner circumferential surface 2a of the main body 2 of the storing device is narrow, a frictional force between both members is reduced and the inner lid 5 can be smoothly opened or closed without any resistance together with the outer lid 4. In addition, an air-tightness between the inner lid 5 and the main body 2 of the storing device can be assured and then a cold air can be prevented from being transmitted toward an inner side even at a cold district.

Title: Method for determination of component in body fluid free from influence with endogenous and exogenous substance
Inventor: ARIMURA KUNIAKI
IPC: C12Q1/28
Filed: 1983-09-09
Abstract: PURPOSE:To eliminate the influence of the interference of an endogenous and exogenous substance, and to determine the component in a body fluid with simple operation, by oxidizing the interfering substance in the presence of a dehydrogenase during the determination process, and reducing the NAD(P)<+>. CONSTITUTION:An endogenous and exogenous substance or their derivative exhibiting interfering action during the determination process, is oxidized in the presence of a dehydrogenase to eliminate the interference activity, and at the same time, the NAD(P)<+> is reduced. The produced NAD(P)H is oxidized in the presence of a diaphorase to the original NAD(P)<+>. When the system contains a catalase, the product is immediately oxidized with the dissolved oxygen in the reaction liquid to generate H2O2, which is decomposed and eliminated by the action of the catalase. When a peroxidase is present in the system, the product is oxidized with dissolved oxygen to produce water. The color development of formazan at the final stage is proportional to the content of the component, and accordingly, the amount of the component can be determined accurately by colorimetry.

Filed: 1996-06-26
Abstract: PROBLEM TO BE SOLVED: To excellently connect a semiconductor element to an aluminum wiring pattern on an insulating substrate through a bump electrode formed by successively laminating an Au4 Al layer and thin Au film upon a gold bump. SOLUTION: A laminated film in which a thin Au film 8 is laminated upon an Au4 Al layer is formed on a bump 6 used for connecting a semiconductor element 2 to an aluminum wiring pattern 11 on a substrate 9. Therefore, only the Au film 8 on the outermost surface of the bump 6 and aluminum existing in the surface of the pattern 1 and its vicinity contribute to the connection to the bump 6 on which a Au-Al metal-tometal compound is formed. The aluminum in the lower section of the pattern 11 does not contribute to the solid-phase diffusion reaction with the surface of the bump 6, but stays in the original state. Therefore, the semiconductor element can be connected to the aluminum wiring pattern on the insulating substrate in an excellent state through the bump electrode.
