Title: Information processing system
Inventor: HANADA TADASHI
IPC: G06F13/12
Filed: 1982-10-08
Abstract: PURPOSE:To use effectively an interface between a channel controller and a channel, by incorporating a memory section storing a channel address, an input/ output device address, and interruption information in a channel controller. CONSTITUTION:A channel CH transmits an initial interruption request signal IT to a channel controller CHC. When a response RS from the device CHC exists, the channel CH reports the channel address, input and output device address and interruption information. The CHC gives an interruption request to the CPU and stores each information to a memory MEM. When the CPU informs the receivable state, the device CHC reports the memory MEM information to the CPU. Since the interruption request is transmitted and the receivable information is returned between the CPU and the CHC, the interruption request of the memory MEM of the CHC is increased/decreased with time. When the memory MEM is idle, the interruption is finished.

Title: Flux cleaning agent
Inventor: MATSUMOTO KATSUO
IPC: B23K1/00
Filed: 1990-07-09
Abstract: PURPOSE:To obtain a flux cleaning agent which exhibits high detergency and good finish comparable with those of the conventional fluorocarbon or chlorine- base solvents by compounding specified alcohols and fatty acid esters. CONSTITUTION:A flux cleaning agent comprising at least one member selected from the group consisting of 3 to 4C alcohols and fatty acid esters. The cleaning agent has good detergency and finish comparable with those of the conventional fluorocarbon or chlorine-base solvents and does not destruct ozone. Further, the conventional apparatus for flux cleaning can be used substantially as they are, since the cleaning agent can easily be recovered by boiling or distillation by the use of a washing machine and a distiller which have been used for the recovery of the conventional fluorocarbon or chlorine-base solvents. In addition, water rinse for removing the cleaning agent from the washed article is not necessary in working steps, since it has a low boiling point and thus the washed article is ready to dry. Accordingly, there is no possibility of polluting water environment with waste water.
