摘要： PROBLEM TO BE SOLVED: To provide an adaptor and a lock for an excavating tooth, enhancing stability for the attachment of a pointed end by providing a supporting surface extended approximately in parallel with the vertical shaft of the excavating tooth. SOLUTION: The adaptor is used for the excavating tooth composed of a rear base end for being fixed for engagement to an excavating blade of an excavator and an end protruding forward for the attachment of an abrasion member. The end, having the vertical shaft and a front end, is defined by a pair of convergent walls, which are tapered toward the front end, a pair of side walls, a plurality of the first supporting surfaces, which are extended approximately in parallel with the vertical shaft, and a plurality of the second supporting surfaces extended approximately in parallel with the vertical shaft. An interval between the first supporting surface and the vertical shaft is made wider than an interval between the second supporting surface and the vertical shaft. Additionally, each of the first supporting surfaces is located between one of the convergent walls and one of the side surfaces.

摘要： PROBLEM TO BE SOLVED: To improve measurement accuracy, to reduce the diameters of external tubes of a measuring device, to reduce the cost, and to prevent a failure by placing tubular bodies each filled with a fluid in an object to be measured and obtaining the amount of subsidence from the difference of fluid pressure caused by displacement at the time of subsidence. SOLUTION: Tubular bodies each filled with a fluid are placed in an object to be measured, and the amount of subsidence of the object to be measured is obtained by the differences of fluid pressure caused by the displacement of the tubular bodies at the time when the object to be measured subsides. In other words, fill tubes 3 are each filled with the fluid in a fluid tank 5 via branch tubes 31 by actuating a pump 51 and opening a group of solenoid valves 52. As a long tube 8 and a measuring tube 1 are displaced following subsidence at the time when the ground of a building subsides, a displacement occurs in a terminal device 2 in the measuring tube 1. As fluid pressure in the measuring tube 1 is changed consequently, it is possible for fluid pressure measuring devices 4 to read the pressure differences and convert them into the amount of subsidence. As it is possible to obtain the amount of subsidence of the object to be measured directly from the differences of fluid pressure in this way, and since secondary calculation is unnecessary, it is possible to improve the measurement accuracy.

摘要： PROBLEM TO BE SOLVED: To simplify constitution of a roof, to relieve the number of processes, improve workability, and to reduce a cost by a method wherein a heat insulation panel for a roof being light and high in strength is utilized as a structural material for a roof. SOLUTION: A heat insulation layer to fill a honeycomb cell with phenol resin foams is provided and a heat insulation panel 22 for a roof is light and high in strength in addition to heat insulation ability, heat resistance, fire resistance, sound absorbing qualities, low smoking properties, and low toxicity. A plurality of heat insulation panels 22 for a roof are horizontally connected on a main house or a steel frame 21 serving as a beam, and a waterproof layer 23 is formed on heat insulating panels 22, 22... for a roof.

摘要： PURPOSE: To easily fit a pin by converging both ends of a rear wall of a hole for a pin at a tip outwardly relative to a front wall at a specified angle of inclination, and providing three projections not on the same plane before the pin. CONSTITUTION: An approximately perpendicular wall behind a hole 18 for a pin at a tip is inclined at both ends by about 15 deg. so as to be outwardly convergent relative to a front wall to form an inclined rear wall 24'. A plurality of projections 19 are provided on the front wall of the hole 18. A lock pin 15' is formed complementarily with the hole 18 for the pin, and the inclinations 26', 29' of about 15 deg. are given to both end parts of the rear side so as to be adapted to the inclined rear wall 24' of the hole 18. In addition, three projecting parts 20, 20', 20' not on the same plane are provided on the front surface of the pin 15' and engaged with the projections 19 provided on the front wall of the hole 18.
