Title: Resin-coated metallic sheet and its production
Inventor: HIKINO SHINYA
IPC: B05D7/14
Filed: 1995-05-12
Abstract: PURPOSE: To continuously conduct chromating and formation of a resin-coating film at the time of applying a water-dispersible resin soln. on the chromate coating film of a metallic sheet and baking the soln. to form the resin-coating film by adding a basic compd. to the soln. and adjusting the pH. CONSTITUTION: An uncoiled metallic sheet is dip-coated with a coating-type chromating soln. in a chromating tank and dried with a drier. A water- dispersible resin soln. is applied on both sides of the sheet after leaving from the drier and then immediately baked in an oven to form a resin-coating film, and a resin-coated metallic sheet is obtained. At this time, the resin soln. is controlled to >=pH9 by adding a basic compd. Consequently, since the dispersion stability of the soln. is maintained even if the chromate component is mixed in the soln., the chromate film need not be completely dried, and the resin- coating film is continuously formed in the same line in succession to the chromating stage.

Abstract: PURPOSE:To obtain a light and compact ultrasonic motor by performing press contact and separation of a rotor and an oscillator through a second piezoelectric element. CONSTITUTION:When a high DC voltage is applied on each piezo element 31 in a piezoelectric laminate 30 and an AC voltage is applied on a piezoelectric element 60, coaxial downward elongation takes place according to the elongation of each piezoelectric element 31 with the flange 21 of a rotary shaft 20 as reference, and a hollow disc 40 displaces coaxially downward together with the rotary shaft 20 thus bringing a rotor 50 into coaxial press contact with an oscillator 70.

Consequently, the rotor 50 press contacts with the oscillator 70 and receives traveling wave therefrom thus rotating the rotary shaft 20. Consequently, selective press contact between the rotor 50 and the oscillator 70, which is required for rotation of an ultrasonic motor, can be realized through function of a light and small dimension piezoelectric laminate 30.
