Abstract: Hair tweezers comprising a pincette member which is retractable by means of a spiral spring immediately after the pincette member is pressed to grasp an objective hair. The hair tweezers have a cylindrical casing in which there are provided a stopper which locks the pincette member in position against the resilient force of the spiral spring and an actuator assembly such as the aforesaid spiral spring. Buttons each having bearing elements therein are provided at the fore portion of the casing in such a manner that the pincette member is unlocked with the stopper and slidably retracted immediately after the buttons are pressed.

Abstract: An improved hand stamp for numbering, dating, etc. is provided. The stamp has printing belts, a shaft and a plurality of polygonal members. The shaft has a protrusion along the entire length, and the polygonal members have a through-hole and a plurality of grooves on the circumferential surface of the through-hole such that the position of the polygonal members may be fixed by an engagement between the protrusion and the grooves. The printing belts are rotated by a rotation of the polygonal members about the shaft against the engagement between the protrusion and the grooves.

Abstract: A casing, in which a powdered substance to be sieved is fed, is provided with a handle portion containing a battery therein. A supporting arm extends from the inner wall of the casing and is connected with a vibratable motor cover at the center portion of the casing. A motor is mounted within the motor cover, and a weighted member is eccentrically connected to the output shaft thereof. The meshed member of the sieve is connected to the motor cover.
