Abstract: PROBLEM TO BE SOLVED: To certainly detect abnormal vibration generated at a time of abrasive deterioration by adjusting the vibratory spiral length of a spiral tabular member to allow the inherent vibration frequency thereof to coincide with the frequency of a rotary machine detecting acceleration. SOLUTION: Piezoelectric elements 11A, 11B are formed on both surfaces of a spiral vibration plate 12 to produce a spiral tabular member and, after the vibratory spiral length thereof is adjusted, one end of the spiral tabular member is attached to a fixing end and a wt. 14 having a predetermined wt. is attached to the other end thereof and fixed by a fixing screw 15 after the attaching position thereof is adjusted. By a spiral tabular vibration mechanism, the spral tabular member becomes equivalent to such a state that a circular arc angle is made large and the resonance frequency thereof can be adjusted up to low frequency of 20Hz or less. When resonance frequency becomes low, effect such that charge sensitivity increases is obtained. Since the adjustment of spiral length is large, the variable range of the resonance frequency of the vibration mechanism can be expanded.

Title: Production of temper rolled stainless steel material having uniform gloss
Inventor: TAKAHASHI MASANORI
IPC: B21B3/02
Filed: 1992-03-31
Abstract: PURPOSE:To produce a temper rolled stainless steel material having uniform luster by subjecting a cold rolled material obtd. by atm. annealing as intermediate annealing and pickling to temper rolling after previously removing the oxide layers on the surfaces of the steel sheet. CONSTITUTION:The oxide films as represented by SiO2 are included into roll coating layers and the unstable roll coating is resulted if such oxide films exist on the surfaces of the cold rolled material obtd. by subjecting the material to the atm. annealing as intermediate annealing and pickling during cold rolling. The partial peeling of the roll coating, therefore, arises during temper rolling and such peeling leads to the nonuniform roll coating. The unequal luster is eventually resulted. The oxide layers of the steel sheet surfaces are, thereupon, removed prior to the temper rolling and the roll coating at the time of the temper rolling is uniformlaized, by which the unequal luster of the temper rolled material is prevented. The removal of the oxide layers is satisfactory, as far as the SiO2 layers formed on the inner side of the oxide layers of Cr are removed. The methods thereof include, for example, wet blasting, belt polishing, etc.
