Title: Apparatus for measuring height of center of gravity of container
Inventor: UEDA SADAO
IPC: G01M1/12
Filed: 1993-08-24
Abstract: PURPOSE:To estimate accuracy of the height of the center of gravity of a container by comparing the weight of the container obtained by a specific formula with that measured by a correct scale. CONSTITUTION:After adjusting of a zero point, that is, after a beam 3 is balanced, a to-be-measured container is held by a holding body 6 horizontally. A weight 4 on the beam 3 is moved to the right and left to adjust and balance the beam in the right-and-left direction. A moving distance of the weight 4 when the beam 3 is balanced is read. Supposing that a distance between a fulcrum of the beam 3 and a bottom face of the container is L1, the moving distance of the weight 4 is X1 (represented by (+) when the weight moves to the right, and by (-) when the weight moves to the left), a weight of the weight 4 is W1 and a weight of the container is W2, a height Y of the center of gravity of the container is obtained according to Y=L1-(X1W1)/W2. In other words, if the moving distance of the weight X1 is obtained, the height Y can be operated since the L1, W1 and W2 are already known.

Title: Weather resistant tableware
Inventor: KATOU YOSHIMOTO
IPC: A47G19/00
Filed: 1997-08-26
Abstract: PROBLEM TO BE SOLVED: To provide resin tableware having high weatherability. SOLUTION: A resin tray 10 comprises a resin structure 12 and granular radiation materials 14 which have the ruggedness formed by an etching treatment on their surfaces, are approximately uniformly dispersed into this resin structure 12 and radiate electromagnetic waves from their surfaces with the prescribed spectral emissivity relatively low in the radiation rate of a UV wavelength region.

Further, the granular radiation materials 14 are approximately uniformly dispersed into the resin structure 12, by which even the electromagnetic waves arriving at the inside of the resin structure 12 past the spacings among the materials existing in the surface layer part are rapidly subjected to wavelength conversion by the granular radiation materials 14 existing therein.

Title: Water stopper for removing water trap
Inventor: MASUDA TATSUO
IPC: E03C1/042
Filed: 1990-08-30
Abstract: PURPOSE:To prevent the trapping of water near the faucet by a method in which small holes are formed in the lower, left, and right sides of the faucet of a water supply stopper so that the outflow of water is prevented when water is used and water is automatically drained after use of water. CONSTITUTION:A partition wall 10 with small holes 11 of a diameter of several mm in three positions, that is one hole in the peripheral bottom, and two holes in both ends, is fixed to the fitting part of a faucet 1. Water goes out with great power from the holes 11 when the stopper is opened, but not leakage from leak holes 3. When the stopper is closed, water trapped in the faucet 1 leaks from the hole 3 under the gravity and flows out. When the faucet 1 is inclined to left or right side, the water goes out through the hole 3 to outside. The trapping of water in the water supply stopper can thus be prevented to prevent the growth of bacteria.
