IPC: A61C19/04
Filed: 1999-01-11
Abstract: PROBLEM TO BE SOLVED: To objectively present oral cavity health conditions by calculating the overall estimative age from the sound tooth number and the sound gingival sextant number of each person, and constituting the overall estimative age so as to be displayed. SOLUTION: The sound tooth number X1 and the code O sextant number X2 obtained from an inspection result of a dentist are substituted in equation I and equation II to calculate (y1, y2). These calculating values (y1, y2) are substituted in equation III to calculate the oral cavity age Y to be displayed. The obtained oral cavity age Y is compared with the actual age to judge an oral cavity health state. That is, when the calculating oral cavity age Y and the actual age are the same, it shown teeth suitable for one's years, and when the calculating oral cavity age is larger than the actual age, it shows that ageing of the teeth makes progress. When the calculating oral cavity age is small, it shows that youthful teeth are maintained. Thus, the oral cavity health state can be effectively used as an effort target and a guidance index of the dentist by judging the quality of the teeth and the gingiva by the oral cavity age obtained by the equation III.

Title: Tidal pumping system
Inventor: AOKI KATSUJI
IPC: F03B13/26
Filed: 1980-01-19
Abstract: PURPOSE: To pump up seawater from a hermetic tank into a higher tank, by semi- submerging a bottom-open pressure regulating box in the sea and introducing air in the tank pressurized by the rise and fall of the tide into the hermetic tank filled with seawater.  
     CONSTITUTION: A pressure regulating box 3 with openings 2 on its bottom is semi-submerged in the sea, its top being exposed to the air and the secondary hermetic tank 4 being set on it. The box 3 and the tank 4 is communicated with each other by an air pipe 5. The secondary tank 4 is equipped with a pump-up pipe 7 and lift pipe 9, so that seawater can be pumped up into a reservoir 10 through the tank 4. As the pressure in the box 3 is reduced due to the fall of the tide, seawater is lifted in the secondary tank 4, while an air supply valve 11 which is open as the pressure is reduced compensates the pressure to the normal level. As the tide rises, the pressure in the box 3 is increased and seawater in the secondary tank 4 is lifted, which means that seawater is pumped up into the reservoir 10 by virtue of the natural force of the tide.
