Abstract: A method for firmly fixing a hydrophilic polymer on a polyamide surface involves applying a solution containing a phenolic compound to a base material of which at least a part of the surface is a polyamide, and coating the base material with a hydrophilic polymer after applying the solution.

Abstract: A medical device of which the surface exhibits lubricity and/or antithrombotic activity when wet. The medical device includes a base material layer, and a hydrophilic layer that is supported on at least a portion of the base material layer, in which the hydrophilic layer is obtained by forming a crosslinked structure by reacting a compound having plural thiol groups in a molecule with a compound having reactive functional groups binding to the thiol group and hydrophilic groups in a molecule, and the reactive functional groups are thiol groups, alkenyl groups, acryl groups, or methacryl groups.

Abstract: To provide a stent delivery system that can limit/prevent drop-off or shifting of a stent from the balloon. A stent delivery system that is equipped with a main tube-shaped shaft, a balloon provided on the tip of the main shaft, and a stent fitted so as to encircle the balloon, wherein a layer for preventing stent drop-off containing a compound with multiple thiol groups is formed on at least a portion of the balloon surface, and at least the portion of the stent that contacts the stent drop-off preventing layer is made of metal.

Abstract: The switch apparatus includes at least one first card having a switch installed therein or more, and a second card, wherein the first card includes an update unit that, in the case of having detected FDB information that is not present in its own switch, transmits it to the second card, and updates the FDB information of its own switch with the FDB information being transmitted from the second card; and wherein the second card includes a manager that collects the FDB information being transmitted from each first card, updates the FDB information of the switch apparatus, and transmits the updated FDB information to each card.

Abstract: An engine control apparatus includes a valve operating mechanism for transmitting the rotation of a crankshaft to camshafts through a timing wrapping member. A control unit includes a phase detection section that detects the phase of a camshaft relative to the crankshaft, an abnormality determination section that makes, based on the detected phase, a determination whether the valve operating mechanism is abnormal, a threshold storage section that stores determination references as a lower limit threshold and an upper limit threshold, an initial phase storage section that stores, as an initial phase, a phase detected at the time of engine installation, and a phase correction section that corrects the phase detected during engine operation by using the initial phase thereby to calculate a corrected phase. The abnormality determination section outputs an abnormality determination signal when the corrected phase deviates from a determination reference range of from the lower to upper limit thresholds.
