摘要： PURPOSE: To appropriately ventilate a room without spoiling the acoustic conditions of both indoor and outdoor sides, by installing a ventilation fan at the air suction opening side and/or the exhaust opening side and arranging the suction opening and the exhaust opening of a ventilation device forcibly ventilating the room, on a nearly diagonal line of the room. CONSTITUTION: A ventilation fan 13 is actuated to let the flesh outdoor air flow in a room from an external air suction opening 22 and an internal air suction opening 21 through an air suction duct. On the other hand, the polluted air in the room is sucked from an internal exhaust opening 11 to an exhaust duct and further, it is discharged from an external exhaust opening 12 through an exhaust duct. In this time, the internal air suction opening 21 and the internal exhaust opening 11 are arranged on the nearly diagonal line of the room to let the air in the room slowly flow from the internal air suction opening 21 to the internal exhaust opening 11, while the diagonal line made by these openings forming the center of the stream. In this way, the air in the room is smoothly led without any short circuits and hence the room can be efficiently ventilated well.

摘要： PURPOSE: To form an event hall partitioned from a main event space by moving some of seats. CONSTITUTION: Upper stage seats 3a and lower stage seats 4a are arranged on one side of a main event space 2. The lower side projecting part of the lower stage seats 4a are made movable seats 5 and supported in the freely rising/falling state to a boundary part to the main event space 2. The back face of the movable seats 5 is equipped with a stage unit provided with a bendable stage formed of a stage main frame 13 and a stage sub-frame 14, and a movable front stage plate 23 and a rear stage plate 24 provided at the stage main frame 13. The movable seats 5 are erected, and the stage is stretched, and the front and rear stage plates 23, 24 are placed side by side to form an event hall 26 in the position of the upper stage seats 3a.

摘要： PURPOSE:To prevent an acoustic impediment, by a method wherein some of the specified surfaces on three- or four-face cyclorama are composed of slant cycloramas allowed to slant toward a ceiling or composed of acoustic absorption cycloramas. CONSTITUTION:In the case of three-face cycloramas, two faces opoposed to each other are composed of slant cycloramas 3 and acoustically reflected waves are allowed to arrive at a ceiling thereby. The ceiling is composed of an acoustic absorption wall 4 and reflected sound of higher order is absorbed thereby. All of them are composed of the slant cycloramas 3 or either of the two faces opposed to each other is composed of the slant cyclorama 3, if necessary. In the case of four-face cycloramas, at least two face neighboring to each other are composed of the slant cycloramas. As substitute for these cases, in the other case of the three-face cycloramas, two face or at least one face of two faces opposed to each other is composed of an acoustic absorption cycloramas and in the other case of the four-face cycloramas, at least two faces neighboring to each other are composed of the acoustic absorption cycloramas. Combinations of the slant cycloramas with the acoustic absorption cycloramas also meet this requirement. In this way, a flutter echo and the excess of reverberations can be avoided, and an acoustic field at the side of fields can be suitably kept.
