A probe (16) comprises a magnet (20) and a Hall element (22) which are provided in a magnetically impermeable case (18). The Hall element (22) is disposed at the midportion between the two poles of the magnet (28) in parallel with the lines of magnetic force. The presence of a carburized portion in the member to be inspected and the depth of carburization are detected by passing d.c. current across the Hall element (22) and detecting the Hall effect electromotive force produced between the two ends of the element which are opposed in a direction perpendicular to the direction of flow of the current.

Two plastic tubelike members (5, 8) on which an annular protrusion (9) or an annular groove (12) are respectively provided to be used as two constructive block members for assembling valve or joint devices are directly coupled by the present method to assemble such devices. Critical conditions in numerical relation are set forth on the coupling end having the annular groove (12) wherein a deformation process can be controlled to engage the annular groove with the annular protrusion (9) by radially widening motion and axially spring motion in elastic dynamics, while the coupling end having the annular groove is softened by heating to become elastic. High coupling accuracy can be secured with high coupling strength and durability.

Method and device for pressurizing the inner surface of a molded cylindrical article by the step of pressurizing and forming the inner surface of the article while rotating a pressing unit (6a) of pressurizing means (6) relative to a molded article (2) during a period of time which begins immediately after completion of solidification of the article ready for pressurizing and forming, and which continues until the transition temperature of the article has been reached the temperature at which the tensile strength and elongation of the article undergo an abrupt charge. This is performed in order to pressurize and cause the collapse of blowholes and air bubbles in the molded article, and to harden the inner surface thereof.

摘要:
Electronic weighing apparatus has means (1, 9, 11) for providing digital data representative of the weight of an article being weighed. Initial weight data is stored in a memory (33) as correction data for subtraction from further weight data, display means (13,15) being provided for displaying the result of the subtraction in a digital manner. The apparatus has enabling means (17) for enabling storage of the data in the memory (33), which may take place a predetermined period after the turning on of a power supply. The apparatus is provided with means (25) for determining whether the weight data to be stored as correction data in the memory (33) exceeds a predetermined value, and if so to prevent said storage.

In a partially liquid-cooling type forcedly air-cooling system for an internal combustion engine which includes an air-cooled cylinder (4) and a liquid-cooled cylinder head (5), a centrifugal cooling fan (11) is provided in front of a crankcase (3) so as to rotate about the fore and rear axis thereof, and a cooling air delivery opening (29) is provided at the back portion (28) of a draft chamber (27) within a fan casing (24) which encircles the cooling fan (11) so as to orientate at least to the cylinder (4). And a portion (26), which is arranged at the side of the cylinder head (5), of the encircling wall (25) of the fan casing (24) is provided with an opening (38). And the cylinder (4) is adapted to be cooled adequately by the cooling air flow delivered through the opening (29), as well as a radiator (36) is adapted to be cooled effectively by the cooling air flow passing through the opening (38) provided in the encircling wall (25) of the fan casing (24) so that at least a portion of the cylinder head (5) can be cooled intensively.
