Abstract: When a voltage signal is input to input terminals as a positive voltage, the voltage conversion circuit generates a control voltage proportional to an input voltage by a voltage-dividing circuit according to resistance elements, a voltage follower circuit according to an operational amplifier, and a voltage-dividing circuit according to resistance elements. When a voltage signal is input to the input terminals as a negative voltage, since the operational amplifier outputs a power supply voltage according to an input of the negative voltage, the voltage conversion circuit generates a predetermined positive voltage obtained by dividing the power supply voltage by the resistance elements as the control voltage. The predetermined positive voltage is higher than a voltage range of the control voltage when the voltage signal is input as the positive voltage.

Abstract: A synthetic resin container includes a mouth portion and body, the body being squeezed to discharge contents. The body has a flattened shape with a width larger than a thickness. An end on one side in an axial direction along a center axis line of the body is connected to the mouth portion, and an end on another side is closed and formed in a curved shape protruding toward the other side in the axial direction. Each widthwise ends of the body is provided with a bent portion extending in parallel with the axial direction. When the body is squeezed in the thickness direction to discharge the contents, the bent portion is configured to be a starting point when one of a front side wall and a rear side wall opposed to each other in the thickness direction of the body is inverted and deformed toward the other.

Abstract: In a heating and hot water supply apparatus, a heat exchanger for hot water supply includes a primary-side path and a secondary-side path. A bypass path branches from a heating circulation path and is configured such that a heat transfer medium heated by a heating device flows through the primary-side path without passing through a heating terminal when hot water supply operation is performed and then joins the heating circulation path again. A control unit controls a flow rate regulating valve so that a hot water flow rate does not exceed a reference limit flow rate when hot water supply operation is performed. The reference limit flow rate is set on the basis of the smaller one between a maximum heating capacity of the heating device and a heating capacity of the heating device at which an output temperature of the heated heat transfer medium reaches an upper limit temperature.

Abstract: A distribution valve controls a distribution ratio of a heat transfer medium between a hot water supply path including a heat exchanger for hot water supply and a beating circulation path through which the heat transfer medium is supplied to a heating terminal. A bypass flow rate control valve controls a bypass ratio which is a ratio of a flow rate of low temperature water introduced into a bypass pipe that bypasses the heat exchanger for hot water supply to a flow rate of low temperature water introduced into a water inlet pipe. The bypass ratio is regulated so that a hot water temperature detected by a temperature sensor reaches a hot water target temperature. During a simultaneous operation of hot water supply and heating, the distribution valve is controlled so that, when a bypass ratio is low, a distribution ratio is higher than when a bypass ratio is high.
