Title: Method of removing marine life in cooling sea water system for condenser
Inventor: IWATA NOBUISA
IPC: F28B9/00
Filed: 1983-09-14
Abstract: PURPOSE:To remove marine life without a mechanical removing system by introducing part of the intake sea water into a condensor to raise its temperature, which is then routed through cooling water tube and sea water pipe inside the condensor to kill the marine life, and thereafter is released after lowering the temperature. CONSTITUTION:The sea water passing through a water pump 11 at a rate of Q leaves a sea water intake pump room to enter a turbine room, and its Q/3 enters a condenser 10 with remaining 2/Q being released. The sea water of the Q/3 is divided by valves 5, 8 into right and left hand side condenser cooling tubes in the amount of Q/6 respectively, and thereafter is joined to pass through a valve 9 to become a reverse flow of Q/3 via a sea water pump 12. When the output of a nuclear reactor etc. is reduced to lower the amount of heat to 1/2 of the normal operation at this time, the sea water of Q/6 in the right and left side cooling tubes is subjected to three times greater temperature increase, and so, marine life inside the condenser cooling tube and sea water pipe are killed and removed in a short time. Meanwhile, as the temperature of the released sea water is limited to T+DELTAT, the impact to the environment can be minimized.

Title: Optical information recording carrier tightly stuck on both faces
Inventor: YATAKE MASAHIRO
IPC: G11B7/2536
Filed: 1987-07-08
Abstract: PURPOSE:To widen a range for selection of substrates and to facilitate production of light transmittable bases by forming grooves or pits on both faces of the substrate, forming recording layers or the recording layers and protective layers thereon, sticking the light transmittable bases onto these layers and executing recording, reproducing or erasing of information by light from these faces. CONSTITUTION:After the grooves for tracking or pits are formed on both faces of the substrate 1, the recording layers 3, 3' or the recording layers 3, 3' and the protective layers 2, 2', 4, 4' are formed thereon. The light transmittable bases 6, 6' are stuck onto these layers and the recording, reproducing or erasing of the information by the light from the faces on the base sides 6, 6' is executed. Since the substrate 1 formed with the grooves for tracking or pits exists at the center of an information recording carrier, there is no need for transmission of light through the substrate. The range for selection of the materials to be used as the substrate 1 is thereby widened and since use of a flat plate as the bases 6, 6' suffices, the production is facilitated.

Filed: 1988-07-08
Abstract: PURPOSE:To produce a data base in parallel with the retrieving service by providing a means which extracts the words/phrases serving as the indexes out of an input document data to correct them and registers these corrected indexes to the input document data to store them into the data base. CONSTITUTION:A store processing part 21 receives the document data, the document names and the document group names from a terminal, etc., and stores them into a data base 14. At the same time, the part 21 stores the control information into a control memory 15.

An index word correcting process part 23 receives the index word candidate correction data from a terminal, etc., and corrects the index word candidates. An index processing part 24 registers the decided index words to the document data stored in a data base 16 and also to the retrieving service control information stored in the memory 15. Thus it is possible to store properly the document data and to extract and register the indexes via the terminal operations, etc., in parallel with the retrieving service.
