An integrated air compressor and winch is provided that utilizes a single source of rotary motive power for driving both a winch drum and compressor mechanism. A semiconductor device manufacturing method which can suppress peel-off of a low dielectric constant insulating layer from an underlying hydrophobic layer is provided. The catalytic layer includes a layered structure of a first catalytic layer containing platinum andor palladium and a second catalytic layer containing rhodium in the first catalytic section and further includes a third layer containing rhodium in the second section. A controller may determine and transmit the overall efficiency value so that the information display displays the number of efficiency indicators. By such measures, system failure is prevented from being caused by leaking, shortage, freezing, etc. Finally, the microprocessor is configured to execute a configurable operation if the event occurs.
