摘要： PROBLEM TO BE SOLVED: To more effectively suppress generation of a flutter and increase the wind velocity generating a flutter. SOLUTION: Two main cables 1, 2 hanging a bridge dirder 4 suspended between basal chief towers cross each other at the middle position in the axial direction of a bridge. Hanger ropes 5, 6 to hang down the bridge girder 4 from the main cables 1, 2 are obliquely inclined halfway. The main cables 1, 2 are positioned on two perpendicular faces crossing each other. A position in the bridge-axial direction where two main cables cross each other is the geometrical mid-point (middle point) between the chief towers. The rigidity of the two main cables themselveas crossing each other is improved with respect to torsion on installing them and the tortional frequency is increased. Hence, a wind velocity generating a flutter is increased.

摘要： PURPOSE: To prevent deterioration of pump efficiency and reduce noises by setting circumferential width of a valve block at a partition in the vicinity of a top dead center of a piston asymmetircally to the top dead center. CONSTITUTION: A left end 11a of a partition 11 of a valve block 6 in the vicinity of a top dead center P of a piston 4 coincides with the top dead center P1 , while a right end 11b is located at a position on a right side of the top dead center P1 by about 18 degrees. Circumferential width of the valve block 6 is formed asymmetrically to the top dead center P1 . With such a construction, when a rotor 1 is rotated in the direction of A, a cylinder hole 2 is not blocked until an oil inlet 3 of the cylinder hole 2 reaches the top dead center P1 . Accordingly, the inlet 3 is closed before reaching the top dead center P as in the case that the partition 11 is formed symmetrically to the top dead center P1 . It is thus possible to prevent increase of pressure inside the cylinder, and generation of noises.

摘要： PURPOSE:To measure the arranging interval between lugs accurately and precisely in a short time by providing a driving device for moving a base bodies at a specified speed in a specified direction, rollers, a displacement sensor, a pulse generating part and a control part. CONSTITUTION:A motor 26 is driven, and a drum 22a is rotated. Thus a track belt 10 is turned. When a roller 33 is in contact with an inner surface 11a of a base body 11 of the belt 10, the detected signal from a displacement sensor 34 is not inputted into a control part 50. When a roller 32 comes into contact with a lug 12-1, the roller 32 is displaced with respect to the inner surface 11a. When a specified amount is exceeded, the detected signal from the sensor 34 is inputted into a control part 50. The roller 32 is slid on the lug 12-1. When the displacement amount becomes less than the specified amount, the detected signal is stopped, and roller 32 comes into contact with a reference surface. When the belt is turned and the roller 32 comes into contact with a lug 12-2, the same operation as before is performed. The control part 50 computes the arranging interval of the lugs based on the counted number of a pulse counter 43 from the previous input time of the detected signal to the input time at this time and a preset pulse period.
