Abstract: A method of supplying scents to a room of a motor-car. In this method, a scent holder is provided within the room of the motor vehicle, the scent holder containing scents bearing materials for emitting different scents useful for a driver of the motor vehicle. Reference data for respective driving conditions of the motor vehicle are stored, the reference data indicating need for supply of respective scents. After storing the reference data, a driving condition of the motor vehicle is detected for producing an electric drive signal representing the driving condition. The drive signal thus produced is compared with a corresponding reference datum for determining whether or not the detected driving condition requires one of the scents contained in the scent holder. When the detected driving condition requires the one scent, one scent bearing material containing the one scent is selected. Then, the one scent from the one scent bearing material is supplied to the room of the motor vehicle.

Abstract: A main body structure for an underground parking lot has an outer wall formed in a substantially cylindrical shape to define a space under the ground. A radial structural body is formed in and connected to the outer wall to support the same on the inside thereof and to divide the space within the outer wall into plural vehicle accommodation spaces. The underground parking lot constructed with this main body structure includes vehicle accommodation mechanisms which are arranged in the respective vehicle accommodation spaces.

Abstract: The present invention relates to a fragrant air supplying method, supplying apparatus, and a building having a fragrant air supplying system for supplying fragrant air to the rooms. A fragrant-material supplying means supplies fragrant material to a mist-generating means to generate mist either by blowing air or by vibration produced by an ultrasonic-oscillating means. The mist is blown to a surface portion formed at the end of a fragrant-air separating means which separates evaporated fragrant air from mist. The fragrant air is then introduced into holes formed in a fragrant-air discharging means, in which the place of holes are offset from the surface portion toward the downstream of the fragrant air. The fragrant air is then blown into a distributing passage from the fragrant-air discharging means to mix the fragrant air with conditioned-air supplied by an air-supplying means.

Abstract: A method for supplying aromas to a space includes the steps of retaining a plurality of aromatic materials in respective reservoirs, selecting at least one of the aromatic materials according to a predetermined timetable determined on the basis of activities of people in the space at each time, diffusing a predetermined amount of the selected aromatic material in air to obtain aromatized air, and sending the aromatized air into the space. The apparatus for supplying aromas includes a receptor having plural aromas, a controller for controlling the receptor to select one stated aroma from the plural aromas in the receptor according to an influence on people by the stated aroma at a stated time in a day, and a ventilator for supplying an air containing the stated aroma. A facility provided with an apparatus for supplying aromas includes plural zones with each being provided with the apparatus, and plural routes for connecting the zones to each other.

Abstract: A sanitary waste collection system and a method therefor which enable the free disposal of waste at various places in a building, and saves labor required for carrying and collecting the waste. The waste collection system includes charge ports provided at every floor of the building into which are thrown waste stored in waste containers of a certain configuration, vertical transport tubes connected to each floor of the building as well as charge ports, horizontal transport tubes connected to the lower ends of the vertical transport tubes and extending to a waste accumulation area, and an air blowing mechanism for force-feeding air in the horizontal transport tubes, with the diameters of the vertical and horizontal transport tubes and being a little larger than the outer diameter of the waste container in section.

Abstract: The present invention relates to an apparatus for conveying refuse containers in a structure such as an office building. The apparatus includes (a) a generally vertical shaft passing through a plurality of floors in the structure; (b) a longitudinally elongated cab suitable for being positioned in the shaft, the elongated cab containing a plurality of refuse containers in such a manner that the refuse containers are vertically aligned, and having a plurality of lateral windows as portals at least at the top and bottom of the elongated cab for the refuse containers; (c) a first lift installed in the shaft, the first lift moving the elongated cab up and down in a generally vertical line throughout the shaft. Thereby, the refuse containers loaded into the elongated cab are vertically conveyed by the first lift.
