IPC: C09D11/00
Filed: 1999-09-02
Abstract: PROBLEM TO BE SOLVED: To provide an aqueous stamp ink composition, which is free of gas generation and corrosion and is able to provide a metalescent stamp, by compounding a pearl pigment to an aqueous stamp ink composition. SOLUTION: The pearl pigment has a particle size of 500 μm, optimally 5 to 100 μm. The amount of the pearl pigment is generally in the range of 3 to 40 wt.% relative to the total amount of the ink composition. The pearl pigment includes Iriodin 100 Silver Pearl, Iriodin 300 Gold Pearl (trade name of Merck & Co., Inc.) or the like. The pearl pigment may be used in combination with a colorant. If any colorant is not used in combination, a stamp having silver, gold or copper metalescence or iridescence is obtained. When a colorant is used in combination with the pearl pigment, metalescent stamps having different colors depending on the type of colorant are obtained.

Title: Apparatus for suppressing passage flow rate of density difference lock for nuclear reactor
Inventor: HANSU EKANDAA
IPC: G21C1/00
Filed: 1988-10-04
Abstract: PURPOSE: To reduce the rate of a flow that passes a density difference lock drastically by providing a honey-comb structure body made of a group of short pipes that are assembled while being aligned in parallel at a boundary region between two different liquid systems in the density difference lock for a reactor. CONSTITUTION: A reactor core part 1 including a primary cooling system 2 and a pump 3 is installed in a pool 4 that is filled with water and the pool 4 constitutes a secondary cooling system 5 by itself. In the reactor, the systems 2 and 5 are in contact at upper and lower boundary regions 6 and 7. When some sort of abnormal conditions causing increase in a temperature level occur in the reactor, one flow from the system 5 into the system 2 occurs. Since water in the system 5 has a cooling operation at a low temperature and also contains boric acid, it is effective to lower the reactor core to a subcritical condition by absorbing neutron. In this manner, since two liquid systems are divided into upper and lower parts at a boundary region, a device functions as one density difference lock for the two liquid systems.

Title: Time division multiplex communication circuit
Inventor: HONDA NAOTO
IPC: H04J3/04
Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To reduce required memory capacity in the case of allocating one channel to plural continuous time slots while dividing it by comparing a time slot number and a final time slot number and outputting write/read instruction signal when both the numbers are coincident. SOLUTION: A counter 1 is counted up for each time slot and outputs a time slot number TS. When the time slot number TS is coincident with a final time slot number TSL of that channel, a comparator circuit 3 outputs a write/ read instruction signal R/W instructing the writing operation and reading operation of a FIFO. Corresponding to the supply of the write/read instruction signal R/W, a FIFO 2 performs the writing operation and the reading operation and reads out the next channel number CH and the final time slot number TSL. The required memory capacity of the FIFO 2 is just for the number of channels to be used and the memory capacity can be reduced.
