To keep a temperature of an interior of an automotive vehicle at least at a level of an external atmospheric temperature even if the vehicle is parked with an engine being stopped for a long time, an automotive air-conditioning apparatus is composed of a cooling device 12 to be controlled by a controller 13, a pre-cooling device 20 for pre-cooling the interior of the vehicle, and a sub-controller 18 for controlling the pre-cooling device. The pre-cooling device is composed of a cooling thermoelectric element module 22, a ventilation fan 23, a solar battery 21 and a pre-cooling storage battery 24 charged by the solar battery. The sub-controller always operates the pre-cooling device 20 while the vehicle is stopped with the engine being stopped and starts the pre-cooling device 20, for example, one hour prior to a time when the vehicle starts to movement during parking for a long time in an interior parking lot or the like with the engine being stopped so that the temperature of the interior of the vehicle is kept at a temperature that does not so much exceed a set temperature, i.e., at least at the level of the external atmospheric temperature, until the engine is started.

Thus, the cooling fan of the high-pressure radiator can be properly controlled in the supercritical refrigeration cycle.

An adjustable gas block designed to interface with the gas-operating system of an auto-loading firearm. This design provides continuously adjustable gas flow, from fully closed to fully open, in small, discrete, uniform, and fully-repeatable increments.

The design works by means of a click adjustment valve screw which has a number of grooves that are engaged by a spring-loaded detent. As the screw is turned in or out, either by a tool or by an integrated finger-adjustable knob or handle, the clicks of the detent provide both audible and tactile feedback to the user. This allows a user to optimize the operation of a firearm by responding to variations in ammunition loading, bullet weight, atmospheric temperature, cartridge caliber, and for the installation/removal of a silencer, each of which changes the volume and pressure characteristics of the gas-operating system.
