Title: Vehicle body reinforcing steel pipe
Inventor: YAMAZAKI KAZUMASA
IPC: F16L9/04
Filed: 1990-07-18
Abstract: PURPOSE:To secure sufficient absorbed energy and facilitate the machining of both end parts by setting the strength of the length parts 1/4L-5/8L of the center part higher than that of both end parts in the length L of a steel pipe, and setting the variable grade of strength in a region where strength between the center part and both end parts changes, within a specific range. CONSTITUTION:In the whole length L of a steel pipe, the strength of the length parts 1/4L-5/8L of the center part is higher than that of both end parts. The high strength parts at the center do not have to be necessarily in complete symmetry. The dislocation from the center is allowed within a range of approxi mately 30% of the length of the high strength part. The strength is set to be over 80kg/mm<2>, and the variable grade of strength in a region where the strength between the center part and both end parts changes is set to be within a range of 0.2-2.0kg/mm<2>/mm. As a result, the machinability of pipe ends becomes desirable, and high bending strength and sufficient absorbed energy can be obtained.

Title: Water purifier and water purifying device
Inventor: YOSHIZAWA HACHIRO
IPC: B01D19/00
Filed: 1994-08-10
Abstract: PURPOSE:To greatly improve water purifying efficiency and to make the size smaller than the size of the conventional device by installing air diffusion panels to the lower part of an air bubble cylinder installed on the inner side of an outside cylinder, installing a means for accelerating ascending flow into this air bubble cylinder and installing a water permeable far IR generating layer to the inner side of the upper part of the outside cylinder. CONSTITUTION:Fine air bubbles are generated from the air diffusion panels 3, 3 and ascend along line arrows 17 when pressurized air is fed like arrows 15, 16 therein from air hoses 13, 14. On the other hand, the pressurized air blown out like an arrow 18 from the air nozzle 4 ascends in the upper cylinder 2a and applies ascending force over the nearby water. Thus air passes like an arrow 19 relatively vigorously in a far IR generating layer 5, thereby rapidly circulating the water in a water storage tank. The fine air bubbles and the gas, for example, chlorine, separated by the far IR generating layer 5 are discharged outside together with the air through a discharge cylinder. In such a case, the gases are forcibly discharged if a fan is installed into the discharge cylinder. The discharge efficiency is thus improved.

IPC: H01L23/52
Filed: 1981-11-25
Abstract: PURPOSE:To easily realize reproducible continuity between conductors by providing a carbon layer at the contact area of conductor layers in a multi-layer conductor structure. CONSTITUTION:A conductive layer 12 is formed on a insulator substrate or substrate or substrate having insulation film and the first conductive layer consisting of a carbon layer 13 is formed also thereon. Thereafter, the second conductive layer 14 is formed by partly or entirely stacking thereon. The sputter evaporation etc. is used for film formation and the suppter etching etc. is used for manufacturing. Paticularly, after the carbon layer is deposited, the dry etching method is employed. The reactive sputter etching is effective for selective elimination of only the carbon layer. This constitution is particularly effective for the Al system conductor because any oxide is not formed due to existence of the carbon layer and continuity between both conductor layers can be attained easily with excellent reproducibility. When the thickness of carbon layer is selected to several tens of Angstrom  to several hundreds of Angstrom , a contact resistance can also be neglected.
