Title: Cooler for integrated circuit
Inventor: HOTTA SHUJI
IPC: H01L23/473
Filed: 1988-02-10
Abstract: PURPOSE:To reduce a temperature gradient in a passage by cooling a heat transfer plate provided in an integrated circuit with a first cooling member using a first fluid medium, and cooling the first member with a second cooling member using a second fluid medium. CONSTITUTION:Heat generated at a semiconductor element 34 is transferred through a heat transfer plate 36 and a heat transfer 38 to a heat transfer plate 37, which is in contact with refrigerant 21 in a cooling header 11 to be cooled. Since the refrigerant 21 used to cool the plate 37 is also used to cool another heat transfer plate 37 at the downstream side of the header 11, the temperature of the refrigerant 21 rises higher toward the downstream side. On the other hand, refrigerant 22 in a cooling header 12 is supplied in a direction facing the flow of the refrigerant 21 in parallel with the cooling of the plate 37 thereby to cool the refrigerant 21 at the downstream side in which the temperature rises by the header 12. Thus, a temperature gradient in the passage can be reduced.

Title: Target tracking apparatus
Inventor: HONMA KUNIHIKO
IPC: G01S13/70
Filed: 1980-03-07
Abstract: PURPOSE:To acquire a ture target continuously by automatically detecting radio jamming etc. that try to jam a distance tracking system and transfering a target detecting gate with respect to these. CONSTITUTION:Whether tracking was made for an artificial target or not is decided by the change in the target speed detected with a target distance change rate calculating part 17. When a decision circuit 22 detects the acceleration exceeding the maximum acceleration in the distance direction that an ordinary target can take, it outputs positive or negative detection signals 28, 29. If there are these outputs, the true target signal left by the distance gate is detected with a gate circuit 18 or 19 and when coincide these detection signals 25, 26 with acceleration detection signals 28, 29, the distance tracking gate position is instantaneously moved to the position of the target detection gate 23 or 24, whereby the true target is automatically retracked.
