Title: Liquid waste concentrator
Inventor: KAWANO MITSURU
IPC: C02F1/14
Filed: 1991-11-26
Abstract: PURPOSE:To obtain a concentrator where liquid waste is given continuous vacuum evaporation mainly by solar heat when concentrating liquid waste, such as industrial liquid waste to reduce its quantity. CONSTITUTION:Liquid waste 11 in a liquid storage tank 3 flows down in a closed solar evaporating box 2 to circulate it and the evaporating box 2 and a solar heat absorbing tubes 6 are connected in parallel and the evaporated water content in the evaporating box 2 is given thermal expansion in the absorption tubes 6 to release it in the air. Consequently the evaporating box 2 is evacuated to take the latent heat of evaporation away, causing the temperature in the box 2 to be kept lower than that in the tubes 6. Thus vacuum evaporation in the evaporating box 2 is realized and when solar heat is insufficient, it is realized by auxiliary heating.

Filed: 1990-11-14
Abstract: PURPOSE:To decide the disconnection of a bus line by a wafer test without operating an element actually by providing a disconnection check circuit which decides the disconnection of the bus line on the element. CONSTITUTION:The decision of the disconnection of the bus line is performed by applying a gate voltage to a pad 18, and turning on a transistor 17, and connecting a pad 16 to the bus line 6. A TG scanner circuit 5 is operated in such state, and a pulse voltage supplied to each bus line 6 by the scanner circuit 5 is monitored from the pad 16. When such test is performed, those bus lines are disconnected without supplying a low level to a non-selected bus line. A pulse monitored from the pad 16 is measured as the pulse sent from the scanner circuit 5 as it is when no disconnection occurs to the bus line. However, when the disconnection occurs to the bus line, the omission of pulses in accordance with number of disconnection occurs.

Title: Fault occurrence preventing method
Inventor: HASUMI HIROAKI
IPC: G06F9/46
Filed: 1993-11-17
Abstract: PURPOSE:To prevent the same fault from being caused again when a system is restarted after the fault has occurred once. CONSTITUTION:If one task T2 causes a fault of software and there are other tasks T1 and T3 which send messages to the task T2 after the system has been started up, those messages are optionally delayed. Consequently, the arrival order of the message from the tasks becomes different when the messages are delayed from that when not delayed. The process order of the task T2 which has caused the fault is different from that in the fault occurrence, and the probability that the same fault is caused again decreases. Namely, the timing of the operation of the position of a logic error, etc., of a program by the task T2 is shifted to prevent the fault from being caused again.

Filed: 1993-12-13
Abstract: PURPOSE:To shorten the hold time of a repeating transmission line by transferring video information to a buffer arranged at a subscriber exchange at super high speed and performing access from a subscriber terminal to the buffer to which the desired video information is transferred. CONSTITUTION:When the subscriber of a terminal 24b installed on the subscriber side indicates a desired video information number to be observed, the instruction is transmitted through a subscriber transmission line 5b to a buffer 27b. When the desired picture to be observed is stored in a buffer memory, the desired video information is transmitted to the terminal 24b. When there is no desired video information in the buffer memory, however, the request signal is transmitted through a central exchange 22 to the control part of a video information server 23. The control part, which receives the instruction, reads the required video information from a file memory where the video information is stored and managed. The read video information is temporarily transferred to the buffer 27b and presented through a subscriber exchange 21b to the terminal 24b. In this case of transferring the information to the buffer 27b, transfer at super high speed is secured.
