摘要： PURPOSE:To stably obtain a uniform buffer action at the time of opening a cover, by constituting a device in such way that an adhesive substance is filled between a sleeve mounted on a fixed shaft and a rotor engaged with a cover body. CONSTITUTION:By turning a lever 12, a locking lug 14 is separated, and the cover body 4 is turned in an opening direction by the pressing force of a spring 5. A rotary cylinder 6 mounted on the cover body 4 is also rotated, and acts so as to rotate the sleeve 7 through the adhesive substance. Torque functions on a coil 9, however, the coil 9 tightens the fixed shaft 3, and locks the rotation of the sleeve 7. Therefore, a shear force functions on the adhesive substance filled between the rotary cylinder 6 mounted on the cover body 4 and the sleeve 7, and makes resistance for the opening operation of the cover body 4.

摘要： PROBLEM TO BE SOLVED: To provide a door closer low in cost with novel and simple structure simplifying complicated structure by dispensing with a rack, a pinion, a link, and the like heretofore in use. SOLUTION: In this door closer, the oil damper body side is mounted to one of a suitable place around an entrance part for mounting a door, and the door, and the piston rod side of an oil damper is mounted to the other. A piston of the oil damper has a passage which communicates one chamber with the other chamber of a piston storage chamber partitioned by the piston, and a valve element exists near the passage of the piston. The valve element moves with the movement of the piston and is adjustable to secure a large passage cross-sectional area in the opening direction movement of the door and to secure a small passage cross-sectional area in the closing direction movement of the door. The oil damper is provided with a hydraulic pressure release means for allowing a fluid in one chamber of the piston storage chamber to flow out with one rush to a chamber on the opposite side to the piston moving side at the closing terminus of the door. The oil damper is also provided with a spring for energizing the door in the closing direction by the movement of the piston. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To reduce the nitrogen oxides which occur when a mixed gas is burnt while a sufficiently high combustion temperature is maintained, by burning the mixed gas at a specific combustion load in a combustion section composed of a porous mat formed by using many thin metal wires having a specific diameter. SOLUTION: When outside air is introduced to a vaporizing chamber 2 through an air passageway 8, kerosene is also sprayed into the chamber 2 from an oil pipe 9 due to a load produced by the introduced air. The kerosene is preheated into vapor by the temperature in the chamber 2, reaches a mixing chamber 3 where the vaporized kerosene is uniformly mixed with the air, and supplied to a combustion section 1 as a mixed gas. The mixed gas burns on the upper surface of the section 1. The combustion section 1 is composed of a porous mat formed by entwining thin metal wires having a diameter of

摘要： PROBLEM TO BE SOLVED: To prevent a blind expanding arm from being an obstacle to field of view by bending the arm to be collapsed between one end thereof freely turnably fixed to the vicinity of the end of a blind end support rail and the other end thereof freely turnably fixed to the vicinity of the end of a blind take-up shaft. SOLUTION: When a blind 1 wound round a blind take-up shaft 3 is expanded, first and second blind expanding arms 4a, 4b are raised like a V-shape, and first and second left blind expanding arms 10a, 10b are raised like a V- shape. The rising angle θ2 made by the right and left second blind arms 4b, 10b can be made larger than before. Accordingly, in the case of using the blind in rear window of a vehicle, each blind expanding arm is prevented from being an obstacle to the rear visual range to improve the rear field of view as compared with that of the conventional blind device.
