IPC: E06B3/84
Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To obtain a door which can reduce wind pressure when a door is closed and impart a massive feel when the door is opened or closed by providing a heavy material outside the vertical center axis of a hinge type revolving door or forming the outer portion of the door of material having high specific gravity to increase the moment of rotations. SOLUTION: A lightweight door (flush type door) 1, in which plywood is used, is swingably attached to a building through a hinge. A heavy material such as a reinforcing bar 9 is inserted into a stile 4 outside a vertical axis A-A' passing through the center of the door 1 to produce an unbalance between the left and right weights with respect to the axis A-A'. And hence even if the wind pressure is exerted on the door, excessive forces are not required to close the door, while when there is no wind pressure, a certain force is required to open or close the door. And instead of inserting reinforcing bar 9, stile 4 may be formed from materials having high specific gravity. Thus a flush door having massive feel can be obtained.

Filed: 1991-12-27
Abstract: PURPOSE:To quantitatively evaluate the crystal flaw of a lithium niobate single crystal with high sensitivity by determining the coefficient of the function showing the relation between interaction length and the branching ratio of the intensities of light from the branching ratio of the intensities of light measured by directional couplers to calculate standard deviation. CONSTITUTION:A plurality of directional couplers wherein the lengths of interaction parts 6 thereof are changed little by little while a gap 5 and asymptotic parts 7 are kept constant are formed on a lithium niobate single crystal 9 from optical waveguides 8. Next, in the respective directional couplers, the intensities of outputs 3 obtained when light is incident on inputs 1 are measured by detectors 10 to calculate the branching ratio eta (L) of the intensities of light. The most proper perfect coupling length Lc and a phase factor 8 are calculated from the measured values of the branching ratio eta (L) of the intensities of light to calculate standard deviation using the method of least squares. By this method, the crystal flaw of the lithium niobate single crystal can be quantitatively evaluated with high sensitivity.
