Abstract: [Object] It is an object to provide a determination device capable of determining the health risk of a laborer due to the labor load from the measured biological information only by measuring the biological information including the heart rate of the laborer. [Solution to the problems] In order to solve the above problems, the determination device 1 according to the present invention includes a biological information acquisition unit 3 that acquires biological information including a heart rate of a laborer Wi, a model formula storage unit 4 that stores a model formula for discriminating a health risk due to a labor load based on the biological information, and a determination unit 5 that determines the health risk of the laborer Wi based on the biological information of the laborer Wi and the model formula stored in the model formula storage unit 4.

Abstract: A sensor with aging function is provided wherein installation space for an apparatus to perform an aging process and the number of apparatuses can be reduced which enables easy and reliable aging processes and can improve measuring accuracy and enhance measuring reliability of the sensor. The sensor with aging function 10 is attached, through a bonding agent 15, to a high temperature measuring object 14, comprising a block body 12 constructed by integrally forming a sensor main body 11 and an electric heater 13 disposed in a manner to be close to the sensor main body 11 using a molding process, wherein a bonding surface on which the bonding agent 15 is applied is formed on the measuring object 14 side of the block body 12.

Abstract: A sensor and bonding agent for the sensor wherein thickness of the bonding agent interposed between the sensor and measuring object can be kept uniform to maintain uniform bonding force of the bonding agent and a peeling phenomenon of the bonding agent occurring due to a difference in thermal expansion between the measuring object and bonding agent and/or between the bonding agent and the sensor can be prevented. The sensor is attached, through the bonding agent, to a high-temperature measuring object, include a sensor main body having a detecting section, a block body constructed by integrally forming the sensor main body using a molding process. The block body is made of a ceramic-based bonding material that the same as a material forming the bonding agent and, on a side of the measuring object of the block body, a bonding surface of the bonding agent is formed.

Abstract: A reinforced sensor with an optical fiber woven into a fabric, comprising a fabric formed in a manner that a weft yarn is woven thereinto in a direction substantially perpendicular to a warp yarn, wherein an optical fiber is included in at least either one of fibers of the warp yarn and the weft yarn. The optical fiber may function as a FBG sensor.

Abstract: An electrode for a crusher and a crusher capable of increasing energy utilized for crushing are obtained. The electrode 1 for a crusher comprises a central conductor (12, 17) extending along a central axis and having an outer peripheral surface, an insulating member (13, 18) arranged on the outer peripheral surface of the central conductor (12, 17) and a peripheral conductor (15) arranged to enclose the insulating member (13, 18). The peripheral conductor (15) includes a first conductor (14a) and a second conductor (14b) arranged at a space from the first conductor (14a) in the extensional direction of the central axis.
