Abstract: An information recording medium comprising a substrate and superimposed thereon a recording layer composed of Sb, Te and Ge has been found to be advantageously employed, because of its high thermal stability as well as high sensitivity and high S/N ratio, in a system of recording information by exposing an energy beam to a recording medium to cause the exposed areas to be different in optical extinction coefficient from the non-exposed areas.

Abstract: An information recording material comprising a substrate, a metallic recording layer composed mainly of Bi and a Cr layer interposed therebetween has been found to be extremely excellent in C/N ratio as well as in storage stability and archivability. The information recording material of this type can be advantageously employed for video image signal memory, still video recording, and the like.

Abstract: An information recording material comprising a substrate and a metallic recording layer, the metallic recording layer comprising a Bi film containing at least one rare earth element. The information recording material exhibits a remarkably increased sensitivity while maintaining a high S/N ratio. Where the information recording material further comprises at least one stabilizing layer of a metal oxide and/or at least one mixture layer of a metallic compound and a metal, further improvements can be attained with respect to S/N ratio, storage stability and archivability.

Abstract: A method of performing hydraulic pressure test of tubes includes the step of performing hydraulic pressure test of the tube. The ends of a test tube are sealed by using closing caps at the respective opposite ends of the test tube which has been filled with water under a completely air-purged condition. The closing caps are held in place during conveyance of the test tube with the opposite ends thereof sealed by the closing caps, to a position at which the test tube is subject to the steps of a hydraulic pressure test including sealing to prevent the filled water from leaking; introducing high pressure water in the hydraulic pressure test step with the closing caps attached to the test tube; maintaining the inner high pressure of the test tube due to the high pressure water; reducing the inner pressure of the test tube through the closing caps, upon the completion of the hydraulic test; and removing the closing caps from the test tube.

Abstract: In a rolling mill in which at least one of paired work rolls for rolling metal strips is formed to have a small diameter and is backed up by a pair of first intermediate rolls which in turn are backed up either directly by a plurality of backup rolls or indirectly by a plurality of backup rolls through second intermediate rolls, the rolling mill of the present invention is characterized in that a bearing case containing bearings is provided to each end of the small diameter work roll and to each end of the pair of first intermediate rolls supporting the small diameter work roll so that these rolls are supported on the bearing cases through bearings, and hydraulic cylinders are provided for applying independent roll bending forces to the work roll bearing cases and the intermediate roll bearing cases.

Abstract: A recording material comprising a substrate and a metallic recording layer, characterized by further comprising at least one mixture layer of a metallic compound and a metal has been found to have a high sensitivity and a high S/N ratio. When the recording material further comprises a stabilizing layer of a metal oxide and/or a stabilizing layer of a metallic compound, the storage stability and archivability can be improved, and, in some cases, the S/N ratio can be further improved.

Abstract: In a recording material which comprises a substrate, a first stabilizing layer on said substrate, a low toxicity metallic recording layer on a surface of said first stabilizing layer opposite said substrate and a second stabilizing layer on a surface of said metallic recording layer opposite said first stabilizing layer, the improvement wherein the first stabilizing layer between the substrate and the low toxicity metallic recording layer is composed of an auxiliary metal oxide layer as an upper layer and an inorganic compound layer as a lower layer for converting said auxiliary metal oxide layer to a surface-flat glassy material. Such an improved recording material can form, upon exposure to, e.g., a laser beam, excellent holes free of irregularities in shape or profile of hole.

Abstract: Photochromic method utilizing photochromic compositions in which the intensity of color generation is not proportional to light intensity which are produced by incorporating an aromatic amine with a low ionization potential, up to 7.6 EV so that it can be ionized by biphotonic absorption into a stabilizing polymer matrix.

Abstract: A mechanical governor of a fuel injection pump for internal combustion engines is disclosed wherein a structure, which permits a reduction of the reaction force of a control lever as well as the tension of a balance spring, comprises a first support member fixed to the housing of the mechanical governor, a second support member pivotably mounted on a control lever, and a balance spring, one end thereof being connected to the first support member and the other being connected to the second supporting member.

Abstract: A mechanical governor for a Diesel construction vehicle engine includes a centrally pivoted torque lever 32 whose lower end is proximate a stop pin 33 on the lower end of a conventional main spring tension lever 9, and whose upper end is cammed against an adjustable torque spring 29 by an extension arm 19a integral with a conventional speed control lever 18 at low or partial load speed settings. This pivots the lower end of the torque lever 32 away from and out of engagement with the pin stop 33, whereby the torque spring 29 is inoperable and no additional engine slowdown is caused thereby. At full throttle or maximum load settings, however, the extension arm 19a releases the torque lever 32 and the torque spring 29 pivots the lower end of the arm into engagement with the pin stop 33.
