Abstract: Proposed is a detachable mooring system for an offshore structure, including a first tension adjuster connected to an offshore structure, and blocking a pulling chain from proceeding from an outlet of a body toward an inlet, a second tension adjuster connected to one end of the pulling chain and blocking the pulling chain from proceeding from an outlet of a body toward an inlet, a mooring chain having a first longitudinal end connected to one surface of the second tension adjuster body and having a second longitudinal end connected to an anchor on the seabed, a first lead rope having one longitudinal end connected to one end of the pulling chain discharged out through the first tension adjuster outlet, and a second lead rope having one longitudinal end connected to the second tension adjuster body.

Abstract: Provided is a Raman scattering measurement apparatus including a light source which emits light to smoke particles, a filter configured to block light which is incident to the smoke particles and passes through the particle and to allow Raman scattered light to pass therethrough, and a photodetector which detects the Raman scattered light passing through the filter in order to distinguish fire smoke generated due to a true fire from non-fire smoke generated due to daily life or industrial activity. The present invention also provides a fire determination apparatus including a unit which reads a Raman shift from Raman scattered light detected by the photodetector of the Raman scattering measurement apparatus, estimates a smoke component from the read Raman shift, and determines fire/non-fire from the estimated smoke component and a method thereof.

Abstract: There are provided a wrench socket and a method for tightening a high tension bolt. The wrench socket includes: a first housing making partial contact with a nut; a second housing connected to the first housing and coupled to a handle; a marker disposed in the first and second housings for marking a high tension bolt, the nut, and a washer according to a height of the high tension bolt; a gauge disposed in the first and second housings for making contact with the high tension bolt and reciprocating according to a position of the high tension bolt; and an elastic part configured to apply an elastic force to the gauge according to a position of the gauge unit.

Abstract: The present invention relates to a digital device and a method for measuring the axial load of a torque-shear-type high strength bolt. One embodiment of the digital device of the present invention includes: a main body portion which is connected to an electromotive wrench fastening a torque-shear-type high strength bolt; a measurement portion disposed at the main body portion to measure the axial load of the torque-shear-type high strength bolt using a quantity of the electricity from the electromotive wrench; a power supply portion disposed at the main body portion and including a power lead-in portion for receiving an external power supply and a power lead-out portion for supplying power to the electromotive wrench; and a display portion displaying the axial force value measured by the measurement portion.

Abstract: An image forming apparatus, a method of controlling paper feeding thereof, and a computer-readable recording medium containing code to perform the method. The image forming apparatus includes a lift configured to supply loaded paper to a feed roller, a motor configured to move the lift so that the paper reaches and contacts the feed roller, a sensor configured to measure current that flows through the motor, and a controller configured to control driving of the motor according to a measured level of the current.

Abstract: Disclosed herein is an end-cap structure of an oil filter for vehicles. The end-cap includes a base cap which has a hole in a central portion thereof, and a hook cap which is installed in the hole so as to be movable upwards or downwards. In this structure, a surface of the hook cap that comes into contact with the base cap when the hook cap moves upwards is a sealing portion. When the hook cap moves downwards, the sealing state is released and a bypass is formed. According to the structure of the present invention, since the sealing portion of the end-cap can be protected from heat, the quality of the product, the productivity, the economic efficiency, etc. can be enhanced.
