Abstract: The inside of a three-dimensional virtual real space so constituted as to have a real size according to the figure and five senses (auditory sense, visual sense, and so forth) of the user can be continuously used like the real living space. A sensory three-dimensional virtual real space system includes a body hardware server device (1), a dedicated program software application (2) which is a three-dimensional virtual real program inserted or downloaded into the body hardware server device (1) so as to be installable in the body hardware server device (1), and a user-dedicated device (3) connected to the body hardware server device (1) so as to wirelessly communicate with the body hardware server device (1) in real time, wearable by the user, and enabling the user to experience a three-dimensional virtual real space according to the three-dimensional virtual real program.

Abstract: An alerting device has: a shock sensor, mounted to or in the vicinity of a main body of an exposure apparatus being transported, which detects values with respect to shocks acting on the device; a controlling device which determines whether or not values detected by the shock sensor have exceeded predetermined tolerable values; and an alerting lamp which emits alerts based on the determination results made by the controlling device. By doing this, it is possible to provide an alerting device which provides alerts with respect to transportation environment and transportation conditions of precision apparatuses, e.g., exposure apparatuses during the transportation thereof on a real-time basis.
