Title: Check system for soft development execution plan
Inventor: KANEKO RYUZO
IPC: G06F11/28
Filed: 1990-03-09
Abstract: PURPOSE:To check the developed soft with high efficiency by displaying the check list data and the failed instance data corresponding to the items to be checked related with each other on a keyboard display terminal. CONSTITUTION:When a keyboard 5 is operated, a CPU 1 retrieves the check list data corresponding to the check items and the comment data out of a disk file part 2. Then the CPU 1 retrieves the failed instance data corresponding to the check items out of an external image storage medium part 3 and displays it at a display part 6. Thus both data can be displayed related with each other on a keyboard display terminal. Then a check list user can check the developed soft while understanding well the meanings of produced check items. Thus no mischeck is caused at all.

Abstract: PURPOSE:To avoide excessive heating when a downstream device is stopped for enabling the operation by providing a stock conveyor the motion speed of which is variable between a transfer conveyor which supports works in a constant temperature tank and moves at a specified speed and a subsequent process. CONSTITUTION:Rollers 20 are transferred from an application device 10 to be received by a constant temperature tank 30, the rollers 20 are heated as they are transferred on a transfer conveyor 50 in order, and they are placed on a stock conveyor 51 to be carried to an assembling device 60. In the case where a failure or the like occurs to stop the assembling device 60, the application device 10 is stopped At this time, the rollers 20 on the transfer conveyor 50 are heated, and they are placed on the stock conveyor 51. Because the number of transfer jigs 41 in the stock conveyor 51 is larger than that of the transfer conveyor 50, the rollers 20 are placed on all the transfer jigs 41 by setting a motion speed to be lower than normal. After all the rollers 20 on the conveyor 50 are transferred to the conveyor 51, the conveyor 51 is stopped. The rollers 20 are thus prevented from being heated excessively in the constant temperature tank, thereby a constant quality can be kept.
