Title: Rotation sensor
Inventor: NEGISHI MASAMI
IPC: G01P3/483
Filed: 1989-12-29
Abstract: PURPOSE:To detect the rotational speed of a rotary shaft with stable detection accuracy by inexpensive constitution by forming a large number of projections to the outer periphery of the rotary shaft at a predetermined interval and alternately arranging two kinds of dielectrics having different dielectric constants to a cylindrical body along the inner peripheral surface thereof. CONSTITUTION:When a rotary body 1 is rotated, the projections 10 formed on the outer periphery of a rotary shaft are alternately opposed to two kinds of dielectrics 21, 22 and the electrostatic capacity between the rotary shaft 1 and the cylindrical body 2 changes. When a lead wire 14 is connected to an oscillation circuit 3 in order to set the electrostatic capacity formed between the rotary body 1 and the cylindrical body 2 to the frequency variable element of the oscillation circuit 3, since the oscillation frequency of the oscillation circuit 3 changes at the speed proportional to the rotational speed of the rotary shaft 1, the oscillation signal of the oscillation circuit 3 is inputted to an F/V converter 4 to be converted to a voltage level. The output of the converter 4 is inputted to a comparator 5 to obtain the frequency signal proportional to the rotational speed of the rotary shaft. By this method, the rotational speed of the rotary shaft can be detected with stable detection accuracy by inexpensive constitution.

Title: Hair iron
Inventor: OTA TATSUYA
IPC: A45D1/04
Filed: 1998-12-01
Abstract: PROBLEM TO BE SOLVED: To provide a hair iron which shortens the application time, is neat in the finish after the application and hardly damages the hair. SOLUTION: The hair is moved at a prescribed speed between magnets 13 of which S poles are disposed to face each other after the application of a first liquid to the hair. Reduction energy is, therefore, generated from the S poles of the magnets 13 in which the electrons of the magnetic poles are rotated clockwise by Fleming's right-hand rule. As a result, the reduction effect of the first liquid is accelerated. A cuticle is closed to prevent the intrusion of UV rays into the hair. The clusters of the water of the first liquid are made smaller by the reduction energy and the penetratability of the first liquid into the hair is enhanced. Consequently, the reduction effect of the first liquid is further accelerated and the time required for the application which is liable to be accompanied by the damage of the hair may be shortened. Accordingly, the finish after the application is made neat and the hair may be made hardly damaged.
