A hot water supply device and a hot water supply system are provided. A controller actuates a circulation pump at a constant output and actuates a heating mechanism for heating by a combustion mechanism when an instantaneous hot water operation is started in response to a temperature drop of a fluid while hot water supply of a hot water supply tap is stopped, until a minimum drive time elapses. The minimum drive time is set based on a flow rate detection value of a flow rate detector under a condition that the circulation pump is actuated at a predetermined constant output and an instantaneous hot water circulation path is formed.

Hot water supply device and hot water supply system

A polyoxyalkylene polymer including a main chain structure of a polyoxyalkylene and terminal structures bonded to ends of the main chain structure is provided. The terminal structures include a hydrolyzable silyl group and further include a terminal olefin group and/or an internal olefin group. The total number of the hydrolyzable silyl, terminal olefin, and internal olefin groups is more than 1.0 on average per terminal structure, and the ratio of the number of moles of the hydrolyzable silyl groups to the total number of moles of the hydrolyzable silyl, terminal olefin, and internal olefin groups is from 0.3 to 0.7.

Polyoxyalkylene polymer and curable composition

One aspect of the present invention relates to a naphthyl phenyl ether compound represented by formula (1): in the formula (1), Rand Rare the same or different and each represent a linear or branched hydrocarbon group having 6 to 28 carbon atoms; m and n are each a real number of 0 or more and satisfy 1.0≤m+n≤3.0.

Naphthyl phenyl ether compound and lubricant composition containing same

An aspect of the present invention relates to a lubricant composition containing at least: (A) 50 to 80 mass % of silicone oil represented by formula (1) below, and having a mass-average molecular weight of 900 to 4000, a ratio (C/Si ratio) of carbon to silicon of 3.03 or higher in the structure, and a viscosity index (VI) of 300 or higher; (B) 10 to 49 mass % of hydrocarbon-based lubricant; and (C) 1 to 10 mass % of antioxidant.
