Filed: 1979-09-13
Abstract: PURPOSE: To convert the heat of a water cooling zone to electricity to recycle the heat and improve environments by leading the steam and air of high temperatures from the water cooling zone of a continuously cast ingot to a heat exchanger.  
     CONSTITUTION: The molten steel 2 poured from a tundish 1 into a mold 3 is cooled with sprays 6 while it is being drawn by roller groups 6. At this time, the water contacting the ingot 4 of high temepratures becomes steam instantaneously, and partly becomes hot air. The condensed water is then discharged from the underside of a heat-insulating hood 8 into a pit 9. ON the other hand, the mixed fluid of steam and air of high tempratures is discharged from the top of the heat-insulating hood 8 by a blower 10 and is led into a heat exchanger 12 via a conduit 11. The sensible heat of the steam and the heat of the air are transferred to the 2nd medium 13 to condense the steam to water; at the same time, the medium 13 evaporates to a high pressure and the vapor is sent into a turbine 14 so that it is converted to electric energy by a generator 15.

Filed: 1982-07-07
Abstract: PURPOSE:To perform tracking always accurately, by a method wherein usual step tracking is not performed when a signal level is abnormally lowered or varied and carried out according to a stored locus stored at the time of fine weather. CONSTITUTION:The output level of a receiver 4 is monitored by a control signal generator 7 and, when said output level is lowered to a predetermined level or varied to a predetermined variable level or more, a control signal is sent to a step direction determining logical circuit 3' to issue an order from the circuit 3' so as to be coincided with the antenna angle at the time of a previous day corresponding to the present time stored by a locus memory circuit 8. By this order, an angle signal is generated by an angle signal generator 2 to operate a drive motor 6 and an antenna is rotated. When the output level of the receiver 4 becomes normal, a control signal is sent to the circuit 3' by the generator 7 to perform the change-over of usual step tracking operation. By this method, an angle locus is renewed by the circuit 8 which is, in turn, operated so as to renew a new angle locus.

Title: Storage rack for spent fuel
Inventor: NAKAHIGASHI SHIGEO
IPC: G21C19/40
Filed: 1989-05-15
Abstract: PURPOSE:To enhance an absorption power of neutrons discharged from a spent fuel and to enable a semi-permanent use as well by forming a cell with a metal solely containing a B-10 or containing B-10 compounds. CONSTITUTION:As member parts forming a cell 2, a stainless steel added solely with a B-10 having a neutron absorption cross-section of 4,017 barns, for instance, is used. In other words, a composition of the stainless steel is controlled by an ordinary method and then 1wt.% B-10 is solely added and is mixed by melting to produce a 3mm thick stainless steel member. In case of a boron containing stainless steel using solely the B-10, the stainless steel has a higher neutron absorption rate by 5 times compared to an ordinary stainless steel added with the same amount of a natural boron. Also, it is rather hard to add the boron by more than 1% with respects of its workability, weldability and the like, however, in case of the B-10, an addition amount can be reduced to one fifth of the natural boron. Moreover, the B-10 added stainless steel is highly corrosion resistant, so that it can be used semi-permanently.

Title: Heat transfer pipe with inner surface grooves
Inventor: FUKATAMI TAKAO
IPC: F28F1/40
Filed: 1999-04-26
Abstract: PROBLEM TO BE SOLVED: To improve a heat exchanging efficiency while suppressing a pressure loss by forming many fins extending in a zigzag manner circumferentially on the inner peripheral surface of a metal pipe and forming recessed parts in at least a part of straight line parts of these fins. SOLUTION: A heat transfer pipe 1 with inner surface grooves is formed of metal such as copper, aluminium and alloy thereof, etc., and many fins 2 extending in a zigzag manner circumferentially are formed in parallel on its inner peripheral surface. Grooves 4 are formed between the fins 2. Further, a recessed part 6 is formed on at least a part of the straight line part of each fin 2. Thus, a part of heating medium liquid flowing in the heat transfer pipe flows along inclined fins and a part thereof passes the fins through the recessed parts and is collected to fin bent points as bottoms for the heating medium flow and flows over the fin bent points. Thus, the ratio of the amount of heating medium liquid passing the fins to the amount of heating medium liquid flowing over the fin bent points becomes appropriate.  Accordingly, the pressure loss of the heating medium passing the heat transfer pipe with the inner surface grooves can be reduced and a heat exchanging efficiency can be improved.
