Title: Temporary pavement structure for reducing difference of level between manhole and bed road face
Inventor: YUI MASAMI
IPC: E02D29/12
Filed: 1996-10-16
Abstract: PROBLEM TO BE SOLVED: To simplify the execution and withdrawal of a temporary pavement structure by composing a level difference reducing temporary pavement structure of the upper end member of a manhole pipe exposed to a bed road face before pavement of fan- shaped members which are divided and annularly connectedly arranged on an outer periphery upper edge. SOLUTION: A level difference reducing pavement structure 1 is composed of eight of the same-formed reducing members which are fittedly connected on the outer periphery of the upper end member 2 of a manhole pipe in an annular area concentric with a manhole 4. A fiber-shaped rubber chip is formed with an urethane binder, and each reducing member used as an elastic paving material is provided with a projected part and a recessed part which are mutually fitted on an adjacent joined face. The reducing member gradually thins from the upper end part of the manhole pipe toward the outer edge of the annular area. Thus in an execution site, the eight reducing sectorial members can be flatly arranged and executed around the upper end member 2 of the manhole pipe as they are mutually fitted.  The level difference reducing pavement structure can be therefore inexpensively manufactured, and easily executed and withdrawn in a short time and moreover reused.

Abstract: PURPOSE:To provide a water retaining function so as to suppress a heat island phenomenon. CONSTITUTION:A drain material layer 3, an earth layer 4 and a porous artificial lawn sheet 5 respectively of specified thickness are laminated in this order on a concrete layer 1. Rainwater or the like thereby permeates the earth layer 4 through the holes of the artificial lawn sheet 5, and water is retained therein by the water retaining action. The water in the earth layer 4 is gradually transpired through the holes of the artificial lawn sheet 5. The texture similar to natural lawn can be thereby imparted to the artificial lawn so as to inhibit a heat island phenomenon at a place where the artificial lawn is laid.

Further, the high frequency component in this signal is removed to perform waveform shaping by a wave from shaping part 11. Next, a pulse counter 12 detects one cycle of the signal from the wave form shaping part 11 and counts the reference clock contained therein. The reference clock is applied to a comparing part 14 through a comparing counter 13. The number of reference clocks at the stop time of the scales 1, 2 are preset in the comparing part 14 as reference values and compared with the counting result of the counter 12 to detect the relative moving direction and distance of the scales 1, 2.

Title: Method for reducing unslagged calcium oxide and magnesium oxide in slag
Inventor: TAWARA EIJI
IPC: C21C5/54
Filed: 1998-09-28
Abstract: PROBLEM TO BE SOLVED: To reduce the unslagged CaO and MgO remaining in the slag by adding a material containing a specific ratio or more of alumina in a reaction vessel lined with a refractory and executing refining of molten metal while using the slag containing a specific ratio or higher of the total of CaO and MgO. SOLUTION: This refining of molten metal is executed by adding the material contained by wt. basis of >=5% alumina and using the slag containing >=40% the total of CaO and MgO. It is desirable that the refining is Cr ore smelting reduction in molten iron and the material containing >=5% alumina is >1.0 the ratio of Al2O3 and SiO2 in the waste refractory.

The expansion and the powdering in the cooling process of the slag and the hydrating expansion at the utilizing time, are restrained and the slag can be used to subbase course material, etc.

Abstract: PURPOSE:To suppress fixed noises which are unnecessary for a display signal at any time by combining two relative azimuth processing systems which differ in integration time with an absolute azimuth processing system which performs exactly the same processing. CONSTITUTION:A certain relative azimuth received beam output selected by a multiplexer circuit 1 is inputted to processing circuits of two systems.
