Title: Heat-transferring device
Inventor: UMEOKA TAKASHI
IPC: F24S90/00
Filed: 1998-10-23
Abstract: PROBLEM TO BE SOLVED: To select desired heat supply temperature from a heat source with unstable temperature, and to stabilize the heat supply temperature to a heat-storing tank and a load, by setting a heating medium to fluid containing a latent heat storing material in a heat- transferring device for transferring heat by a heat-transferring circulation system being connected to the heat source via the heating medium. SOLUTION: In a solar energy heating hot water supply system 10, heat-transferring circulation piping 13 is provided, where the piping 13 allows a heating medium to circulate between a solar energy collector 11 (a heat source) and a heat-storing tank 12, and at the same time a load 14 and an auxiliary heat source 15 are connected to the heat-storing tank 12. In this case, fluid including the latent heat storing material is used as the heating medium of the heat-transferring circulation piping 13.  When heat source temperature (solar heat collecting temperature) becomes higher than selection temperature (the phase change temperature of the latent heat storing material), heat from the heat source is subjected to latent heat transfer for transferring to the heat-storing tank 12 and the load 14 as far as the range of the amount of latent heat until a phase change where the latent heat storing material is melted from solid to liquid is completed is not exceeded, thus performing heat transfer by using the selection temperature as the heat supply one to the heat-storing tank 12 or the like by the heating medium even when the amount of heat collection in the heat source with unstable temperature is large.

Title: Pattern generator for ecc
Inventor: YAMABE MORIHIRO
IPC: G06F11/10
Filed: 1989-11-22
Abstract: PURPOSE:To eliminate a need to generate an ECC (error correction code) pattern by computer operation by simultaneously reading out expected value data in an expected value memory for large-capacity ROM and check matrix data at the time of executing the test. CONSTITUTION:Data in a memory 1 and data in a memory 2 are inputted to an AND circuit 3. For example, a first row of the AND circuit 3 operates AND between data in the memory 1 and data of a first row in the memory 2, and a second row operates AND between data in the memory 1 and data of a second row in the memory 2. An EX-OR circuit 4 outputs '0' when the sum of '1's of the output of the AND circuit 3 is even, and the circuit 4 outputs '1' when it is odd. A shift register 5 takes the output of the EX-OR circuit 4 as the serial input and outputs the output of the EX-OR circuit 4 in parallel. Thus, the ECC pattern is generated in real time to exclude the user's ECC pattern generating work using the computer operation.

Title: Method and system for suppressing false radar image
Inventor: TSURUOKA SHUICHI
IPC: G01S7/295
Filed: 1998-10-26
Abstract: PROBLEM TO BE SOLVED: To suppress the generation of false images based on reflective bodies in a radar device. SOLUTION: Two targets having the same airplane number which occur due to a false image are detected from target data detected by an SSR target detecting part 3. Next, by computing a time difference Δt within radar scan in which the two targets are detected on the basis of one time of the targets, the locations of the targets at the other same time is predicted and computed through the use of past track data to obtain the distance data of the two targets. Then, through the use of the fact that a false target by reflected waves is present at a location farther than a true target by direct waves, the target farther in distance among the two targets is determined as a false target to suppress the false image.
