Title: Air cleaning device
Inventor: HAMADA KENICHI
IPC: F24F7/007
Filed: 1990-05-25
Abstract: PURPOSE:To perform a ventilating function every time the ventilation is required under a most-appropriate controlling operation, always reduce a loss of indoor heat energy with a ventilation fan being always operated and perform a clean ventilation work by a method wherein the most appropriate control is carried out as a system for a device having an air cleaning part and a ventilation function part. CONSTITUTION:An air cleaner 1 is made such that an air cleaning part 3 and a ventilation function part 4 are systematically constructed. If a sensor in a main body 1 judges that gaseous substance can not be removed at the air cleaning part 3, the ventilation function part 4 is operated to remove the gaseous substance. That is, as a gas concentration reaches from a gas concentration V0 to V1, a detected output of a gas sensor 6 exceeds an operation start value of the air cleaning part 3. The air cleaning part is operated to remove gas and dust contamination. A degree of removing gas is not detected during occurrence of gas due to the fact that a concentration of gas is being increased and an attenuation characteristics at the air cleaning part 3 is not apparent. In view of this fact, a transferring point when the air cleaning part 3 is operated to vary the concentration of gas is varied from its increase state to a decreased state, i.e., a point P indicated by a mountain shape in a graph is detected and a degree of removing of gas is judged after a specified period of time, (t) is passed after the point P.

Title: Structure of cooling semiconductor device
Inventor: MINE SHINJI
IPC: H01L23/46
Filed: 1987-05-29
Abstract: PURPOSE:To cool memory-related semiconductor devices by a water cooling system and to shorten a mounting pitch of packages by a method wherein heat-conducting plates are installed around the semiconductor devices acting as heat-generating bodies, the devices are shut up and the heat is conducted to a cooling pipe forming a coolant flow path on the packages via an atmosphere. CONSTITUTION:SIP-type long-sheet-like multilayer ceramic packages (MCP's) 7 where semiconductor devices 8 are mounted on one face are arranged on a printed-circuit board 1. One each long-sheet-like heat-conducting plate 3 is arranged between two long-sheet-like MCP's 7; their upper space is covered with flat-sheet-like heat-conducting plates 4. Cooling pipes 2 such as copper pipes or the like are installed in such a way that they cross at a right angle to a longitudinal direction of the long-sheet-like MCP's 7. The heat generated by the semiconductor devices 8 is dissipated from the surface of the long-sheet-like MCP's 7 whose heat capacity is large; the heat reaches a coolant such as water or the like in the sequence of an ambient atmosphere, the long-sheet-like heat-conducting plates, the flat-sheet-like heat- conducting plates 4 and the cooling pipe 2; the heat is then dissipated to the outside of a package. If the long-sheet-like MCP's 7 and the long-sheet-like heat-conducting plates 3 are retained by keeping an angle theta with reference to the printed-circuit board 1, a height of the package can be suppressed to be lower; accordingly, it is possible to make a mounting pitch of the packages shorter.
