An abnormality in a device of interest is detected on the basis of the distance from a predetermined reference curve to a point represented by a first index value and a second index value in a two-dimensional plane having the first index and the second index as axes.

Abnormality detecting device, abnormality detecting method, and storage medium

The present invention provides a rubber composition which has excellent processability owing to its low rubber viscosity during kneading, despite containing a white filler, and which further has excellent fuel economy and excellent abrasion resistance. Also provided is a pneumatic tire formed from the rubber composition. The present invention relates to a rubber composition including: a rubber component, a white filler, and a compound represented by the formula (1) below, wherein X represents &#x2014;CONH&#x2014; or &#x2014;COO&#x2014;; Rrepresents a C7-C23 alkyl group or a C7-C23 alkenyl group; Rrepresents a C1-C3 alkylene group; and Rand Reach independently represent a hydrogen atom, a C1-C3 alkyl group, or a C1-C3 hydroxyalkyl group, and at least one of Ror Ris the hydroxyalkyl group. 

Rubber composition and pneumatic tire

The present invention provides a rubber composition for tires which can improve crack resistance, ozone resistance, discoloration resistance, and tire appearance while maintaining a good balance between them, and also provides a pneumatic tire formed from the rubber composition. The present invention relates to a rubber composition for tires, containing a rubber component having a combined content of polybutadiene rubber, natural rubber, and polyisoprene rubber of 80% by mass or more per 100% by mass of the rubber component, the rubber composition containing, per 100 parts by mass of the rubber component: 0.1 to 8.0 parts by mass of polyether (A) having a glycol ether content of 80% by mass or more and a HLB of 3.5 to 19.0, the polyether (A) excluding Pluronic nonionic surfactants; 2 to 70 parts by mass of carbon black; and 0.3 to 7.0 parts by mass of an antioxidant.

Rubber composition for tires, and pneumatic tire

The disclosure enables mutual relationships among operation statuses of each motor to be ascertained without using synchronous serial communication between multiple motor control devices. The motor control system is equipped with: a motor driver having a trigger determination part for determining whether or not a trigger condition is satisfied, a trigger notification part for transmitting a trigger notification indicating that the trigger condition is satisfied to motor drivers by asynchronous communication, and a trace result information generation part for causing a storage part to store a trigger data number for identifying operation data when the trigger condition is satisfied; and motor drivers each having a trace result information generation part for causing a storage part to store a slave trigger time at which the trigger notification is received, a trigger data number for identifying operation data corresponding to the slave trigger time, and a master trigger time.

Motor control system, motor control device, and non-transitory recording medium

The present invention aims to provide a rubber composition for tires that can improve processability, crack resistance, ozone resistance, discoloration resistance, and tire appearance while maintaining a good balance between them, and also to provide a pneumatic tire formed from the rubber composition. The present invention relates to a rubber composition for tires, containing: a rubber component; an antioxidant; and polyether, the rubber component having a combined content of polybutadiene rubber, natural rubber, and polyisoprene rubber of 80% by mass or more per 100% by mass of the rubber component, the rubber composition containing the antioxidant in an amount of 0.3 to 7.0 parts by mass per 100 parts by mass of the rubber component, the polyether having an average mass content of at least two consecutive polyethylene oxide units of 85% or less of the polyethylene oxide mass content of the polyether.
