Title: Tension adjustment method for timing belt and device therefor
Inventor: SATO YOSHIHIRO
IPC: F16H7/12
Filed: 1988-10-31
Abstract: PURPOSE:To optimize the tension of a timing belt by fixing a driven side timing pulley after running-in operation, displacing a tensioner with turning torque applied to a driving side timing pulley and fixing the tensioner at the position where reaction from the timing belt becomes a proper value. CONSTITUTION:After a timing belt 6 is subjected to a running-in turning operation, a driven side timing pulley 3 is fixed. On the other hand, while the predetermined turning torque is being applied to a driving side timing pulley 1, a tensioner 8 is displaced and fixed at the position where reaction from the timing belt 6 becomes a proper value. According to the aforesaid construction, constant tension comes to be applied to the tensioning side of the timing belt 6 via the application of torque to the driving side timing pulley 1 during the tension adjustment. Furthermore, by adjusting tension at the loose side of the timing belt 6 with the tensioner 8 in that condition, it becomes possible to make tension adjustment for the timing belt 6 in a condition approximate to an actual operation condition, regardless of the non-operation of the driving side timing pulley 1.

Title: Method for detecting defect in concrete wall body
Inventor: YOSHIDA HIROSHI
IPC: G01N29/12
Filed: 1991-10-23
Abstract: PURPOSE:To suppress the effects of surface waves and the like almost perfectly and to make it possible to detect the defects by arranging a plurality of sensors at the known distances from a striking point on the surface of a concrete wall body, and separating and extracting the first-order reflected wave through a filter having the dead angle for cutting the surface wave and the second-order reflected wave. CONSTITUTION:A plurality of sensors S0-S13 are provided at a specified interval P on the surface of a concrete block CB. A shock is applied to a striking point B, and the incident wave is generated. The time waveforms are observed with the sensors S0-S13. The first-order wave is separated and extracted with a filter having the dead angle for cutting the surface wave and the second-order wave so that only the sound, which is generated in a certain sound source, can pass and the sounds from the other sound sources can be cut. When there is the reflected wave from the wall, this fact is equivalent to the fact that there is a virtual sound-source image at the position of the mirror image with respect to the actual sound source. When a crack is present in block CB, the virtual sound-source image appears because of the wave from the crack. Thus, the crack can be detected.
