Title: Carpet maintenance machinery
Inventor: MATSUDA EIJI
IPC: A47L11/34
Filed: 1987-07-22
Abstract: PURPOSE: To enhance the mite killing effect by giving a plurality of slit-form steam jets an angle relative to the moving direction, and thereby prolonging the steam exposure time to mites living in a carpet. CONSTITUTION: By a water supply pump 36, water is supplied to the first evaporating chamber 29 whose temp. is regulated by a temp. regulator 31 to the optimum temp. for steam generation, and is evaporated in the chamber 29 and spouted to the second evaporating chamber 30 through a hole 28. Within the second chamber 30, the spouted steam is further heated and expanded, and is jetted to the outside air from a plurality of slit-form steam jets 32. Because the jets 32 are formed at a nozzle 35 with the angle θ relative to the moving direction, the steam exposure time is made longer than is conventional arrangement where one row of steam jets are provided with the same slit width (θ=0).

Title: Layout problem resolving system
Inventor: HANDA KEIICHI
IPC: G06F17/50
Filed: 1990-07-12
Abstract: PURPOSE:To reduce the number of checks for determining a layout arrangement position by selecting a reference target out of arranged targets, selecting an unarranged target most adjacent to the reference target laying out the selected target on an unarranged position most close to the reference target. CONSTITUTION:The layout problem resolving system is formed by three blocks, i.e. an arrangement target data input part 1, an layout problem resolving processing part 2 and an arranged result output part 3. The input part 1 inputs data relating to arrangement targets as a table defining adjacent degree indicating the degree of adjacently arranging two optional arrangement targets out of all arrangement targets. The processing part 2 executes the resolving processing of an arrangement problem. Namely, the processing part 2 selects an arranged target as a reference target, selects and determines an unarranged target to be arranged most adjacently to the reference target and then arranges the determined unarranged target. Consequently, the number of times of checking layout enabled positions can be reduced and an layout problem can be simply and efficiently resolved.

Title: Magnetic disk storage device
Inventor: NISHIKAWA KATSUYA
IPC: G11B33/14
Filed: 1981-11-16
Abstract: PURPOSE:To prevent the condensation on the surface of a magnetic disk and to avoid a trouble due to head crash, by keeping the internal humidity of a storage device within a prescribed range with use of a condensation sensor, a resistor and a ventilator. CONSTITUTION:When the relative humidity in a deck 1 reaches approximately 100%, the resistance value of a condensation sensor 11 increases. This increment of the resistance value is detected by a control circuit 12. The detection signal is fed to a positive characteristic heat-sensitive resistor 13 and a ventilator 14 to turn them on. The heat generated from the resistor 13 is sent into the deck 1 by the ventilator 14 as the warm air. Thus the inside of the deck 1 is warmed up to drop the relative humidity. When the relative humidity dropped down to a prescribed level, the resistance value of the sensor 11 also drops. This drop of the resistance value is detected by the circuit 12. Then the resistor 13 and the ventilator 14 are turned off.
