Abstract: The measuring instrument includes a sensor unit that measures a predetermined physical quantity; an amplifier circuit that amplifies a signal output from the sensor unit; and a linear power supply that supplies power to the amplifier circuit, in which the amplifier circuit includes a first amplifier having a first transistor using a SiC semiconductor, the linear power supply includes a second amplifier having a second transistor using the SiC semiconductor, and noise characteristics of the first amplifier are superior to noise characteristics of the second amplifier.

Abstract: In an asset management system, a wearable camera mountable by a police officer and a server that manages information regarding the wearable camera are connected to enable a communication. The wearable camera repeatedly diagnoses whether or not the wearable camera has failure at a predetermined timing, and notifies the server of a diagnosis result. The server is connected to a database, accumulates the diagnosis result of the wearable camera in the database every time the server receives the diagnosis result of the wearable camera, and displays the diagnosis result of the wearable camera on an external terminal.

Abstract: A catalyst selected from a perfluorosulfonic acid and an anhydride thereof enables a non-conjugated drying oil to react with a phenol to form a phenol-added vegetable oil without causing hydrolysis of the non-conjugated drying oil. The phenol-added vegetable oil is allowed to react with an aldehyde to form a vegetable oil-modified phenolic resin. A laminate produced by impregnating paper with the vegetable oil-modified phenolic resin and laminating and molding the impregnated paper is excellent in low temperature punching quality and electrical properties and is free from low molecular weight components oozing out the surface of the laminate.
