Title: Coloring treatment of aluminum or aluminum alloy for developing pastel color
Inventor: ITO SEIICHIRO
IPC: C25D11/22
Filed: 1987-02-25
Abstract: PURPOSE:To form a special colored film with Al ions generated as an impurity when an anodic oxide film formed on Al or an Al alloy is electrolytically colored in an electrolytic coloring bath, by specifying the concn. of Al ions in the bath according to the degree of acidity of the bath. CONSTITUTION:An anodic oxide film is formed on Al or an Al alloy by anodic oxidation and is electrolytically colored in an electrolytic coloring bath contg. a salt of a metal such as Ni, Sn, Ca, Ba or Ti, and a pastel color is developed. When the bath used has high acidity of <2pH, the concn. of Al ions in the bath is regulated to >=5g/l. In case of low acidity of >=2pH, the concn. is regulated to >=1g/l. By this method, Al ions which hinder electrolytic coloring as an impurity can be utilized. Since the color tone of the base is seen through a color tone such as bronze, umber or gold developed by the electrolytic coloring bath, a novel pastel color is developed.

Abstract: PURPOSE:To utilize the motion monitoring function provided to a magnetic bearing and to obtain a small-sized, high-reliability gyro with simple structure by providing a stator on the internal surface of a base opposite to a rotor whose end parts are both supported on the base through the magnetic bearings. CONSTITUTION:The stator 30 is provided on the internal surface of the base opposite to the rotor 21 whose end parts are both supported on the base 22 through the magnetic bearings. When external moment operates on the base 22 while the rotor 21 rotates fast around the base 22, the rotor 21 causes a presession and is to tilt at right angles to the operation direction of the external moment. Displacement sensors 31 detect the displacement of the rotor 21 at both end parts and send detection signals to a controller 40. The controller 40 sends a control current for making the rotor 21 coincident with a target reference position to the coil of the stator 30. The control current signal is sent to an arithmetic unit as well to calculate the direction and quantity of the presession from variation of the control current flowing through the coil of each stator magnetic pole. Further, the direction and quantity of the external moment operating on the base 22 are calculated from the arithmetic results.

Title: Dynamic vector detector
Inventor: KASA HIROSHI
IPC: G06T7/00
Filed: 1985-03-04
Abstract: PURPOSE:To detect a dynamic vector with high accuracy for the movement of a pattern or object in a picture by discriminating that a correlation obtained between split patterns with low correlativity is ineffective and excluding the result from the calculation of dynamic vectors as the parallel movement of the entire picture. CONSTITUTION:A correlation device 13 executes the correlation operation between two-frame picture information which are consecutive timewise with respect to split patterns where one pattern is split into plural parts. On the other hand, a correlativity effectiveness/ineffectiveness discrimination circuit 7 discriminates the effectiveness/ ineffectiveness of the correlativity having the highest correlation at each split pattern based on the correlation value 13 outputted from an accumulator 5 and gives a discrimination signal 16 to a discrimination circuit 8. The discrimination circuit 8 calculates a dynamic vector based on three input signals and gives an output to an output terminal 9. That is, the circuit 8 does not use the correlation value obtained between split patterns in which the correlativity having the highest correlation value is discriminated to be ineffective based on the discrimination signal 16 and calculates the dynamic vector by using the correlation value obtained with respect to the remaining split patterns and corresponding shift.
