Title: Optical recording medium and method for reproducing its information signal
Inventor: HORIKAWA KUNIHIKO
IPC: G11B7/2433
Filed: 1996-09-06
Abstract: PROBLEM TO BE SOLVED: To superfinely reproduce recorded information signals recorded with a high density particularly to a phase change-type reloadable optical recording medium. SOLUTION: The optical recording medium includes a first layer 14 and a second layer 13. When receiving recording light beams carrying information signals to be recorded, the first layer 14 changes from one of two physical states to the other physical state. The second layer 13 layered on the first layer 14 at the side where the light beams are cast changes from one of two physical states to the other physical state when receiving reproduction light beams.  At an area 8 of the second layer (reproduction-assisting layer) changing from the one physical state to the other physical state when the reproduction light beams are cast to the optical recording medium, information signals are reproduced from a difference of reflectances based on a combination of the other physical state at the area 8, and physical states 5, 6 at an area of the first layer (recording layer) corresponding to the area 8.

Title: Tensile force measuring instrument for tension member
Inventor: NAITO SEIJI
IPC: E04G21/12
Filed: 1985-11-19
Abstract: PURPOSE:To make the titled device light in weight, and to easily handle it by making the inner cylinder body of a load cell attachable and detachable to and from the outside periphery of an anchor head. CONSTITUTION:When oiling is started into a hydraulic chamber 25 by operating the hydraulic hand pump of a measuring part, and oiling into the hydraulic chamber 25 advances, the capacity of the inside of the hydraulic chamber 25 increases. As a result, as for an inner cylinder 21 and an outer cylinder 22, force works in the extending direction, respectively, but since the end face of the outer cylinder 22 is abutting on a bearing plate 7, an anchor head 6 is pulled apart from the bearing plate 7 by using the bearing plate 7 as a reaction force surface. In this state, a load for generating the tensile force for working on a PC cable 8, in a load cell 2 is fetched as the variation of an electric resistance. Before executing the oiling, a thin plate material 10 is inserted into the slit of the outer cylinder 22, and the oiling is stopped at the moment when the anchor head 6 and the bearing plate 7 are separated by oiling into the hydraulic chamber 25, namely, the moment when the thin plate material 10 can be inserted between them, by which the tensile force working on the PC cable 8 can be detected.

CONSTITUTION: This emulsion consists of an org. phase comprising a chemical to prevent harmful organisms or a mixture of chemicals, and a water phase comprising a surfactant and/or dispersant. The chemical to prevent harmful organisms is substantially hydrophobic and is liquid or dissolved in a hydrophobic solvent. The emulsion contains a polymer (such as polystyrene and vinyl chloride-vinylacetate copolymer) which is more soluble in the org. phase than in the water phase by an amt. to stabilize the emulsion, preferably 1 to 30 wt.% of the chemical to prevent harmful organisms, especially 1 to 10 wt.%. The emulsion is prepared as a water-based concentrated product and has storage stability. The emulsion does not cause increase in the particle size or phase separation of the emulsion component even it is stored for a long time.  After the emulsion is diluted, the particle size does not substantially change. Since the amt. of the org. solvent is small, the product is allowable from the environmental viewpoint and has little hazard of inflammation and little toxicity for mammals.
