Publication number: US20220049908A1
Application number: 17/453,085

A receiver includes a large diameter main body portion, and an intermediate member side small diameter portion. A wall thickness of the intermediate member side small diameter portion is smaller than a wall thickness of the main body portion. As a result, heat capacity of the intermediate member side small diameter portion is reduced. As a result, it is possible to complete brazing between the intermediate member side small diameter portion and the intermediate member, at the same time as brazing among tanks, tubes, and fins. A desiccant enclosed in a flexible bag can be taken in and out through the intermediate member side small diameter portion.

A load control device includes a power supply terminal connected to a power source via a fuse, a load driver configured to drive loads by electric power supplied from the power source via the fuse and the power supply terminal, a current detector configured to detect load currents that flow through the loads, respectively, and a controller. The controller is configured to calculate a total current that flows through the fuse based on the load currents detected by the current detector, calculate a physical quantity correling with the total current and related to a connecting member that connects between the fuse and the power supply terminal in response to that the total current is equal to or higher than a predetermined current value, and limit at least one of the load currents in response to that the physical quantity is equal to or greater than a reference value.

An audio output device includes PWM output devices, a weighting unit, a mixer, and an amplifier. The PWM output devices divide audio data into multiple parts including an upper bit part to a lower bit part, and output the multiple parts of the audio data as PWM outputs. The weighting unit weights the PWM outputs from the PWM output devices. The mixer synthesizes the PWM outputs after being weighted. The amplifier supplies an electric current to a sounding body in accordance with a synthesis result by the mixer to cause the sounding body to emit a sound.
