Title: Cleaner for interproximal space
Inventor: ISAKA RYUICHI
IPC: A61C15/00
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To remove dental plaque and saburra in interproximal spaces easily, effectively, safely and steadily. SOLUTION: The cleaner consists of a handle, neck 2 that is connected with the handle and cleaner 3 that is settled in the end of the neck 2. The cleaner 3 consists of cone-shaped or polygonal cone-shaped core 4 of which the diameter becomes smaller as it is nearer to the top and plural slits 5 that is formed on the surrounding surface of the core 4 toward the longitudinal direction. The top of the cleaner 3 is for cleaning small interproximal spaces and the opposite end of the top of its diameter is longer is for large interproximal spaces, so it can remove saburra and dental plaque easily and steadily from any size of interproximal spaces. The slits 5 can be elastically deformed as soon as it is inserted into interproximal spaces. Then, the area of the tooth's surface to which it touches will become so larger that more effective cleaning should be done.

Title: Steering stabilized rudder of ship
Inventor: TORIKAI SHIGENARI
IPC: B63H25/38
Filed: 1997-12-04
Abstract: PROBLEM TO BE SOLVED: To improve and stabilize turning performance, course keeping performance and a ship speed by imparting roundness to the front of a rudder, forming a side plate in a wedge shape by expanding it backward, forming a rear plate as a plane, arranging stabilizers at the top and bottom respectively, and installing a rudder shaft in front of the center of a rudder width. SOLUTION: Roundness is imparted to the front of a rudder plate, and a side plate 3 is formed into a wedge shape, and a rear plate 2 is formed as a plane, and stabilizers 1 are installed at the top and botom respectively. Course keeping performance is enhanced since a water flow equally acts on the side plate 3 by forming a rudder into a wedge shape, and vertical diffusion of the water flow from a propeller is prevented by the upper-lower stabilizers 1. Flow pressure is not applied to a rudder main body since the water flow from the propeller is diffused by the roundness of a front part, and a ship speed is increased since advance force acts on the rudder main body by a wake of the water flow when negative pressure is generated backward by the plane of the rear plate 2. Turning performance and the course keeping performance can be enhanced by a wedge shape and the stabilizers 1.
