  • Patent number: 5914880
    Abstract: A system for controlling a manufacturing system including a plurality of working units is described. Each working unit has an operational tool and a unit controller which controls the corresponding tool. Each unit controller includes a storage device for storing data about the status of multiple working units including its own. A data control device is connected to the storage device and the remainder of the unit controllers. The data control device renews unit status data stored in the storage device with the newest data about the status of the working units including that of its own working unit. Thus, all the unit controllers always have the newest unit status data in common. Each unit controller includes a drive control device for controlling the corresponding tool based on the unit status data stored in the storage device.

  • Patent number: 5240808
    Abstract: A light-sensitive composition which comprises at least one polymeric compound having both photocross-linkable groups and functional groups carrying P--OH bonds. The light-sensitive composition can effectively be employed for making lithographic printing plates, IC circuits and photomasks. The light-sensitive composition shows excellent practically acceptable developability with either of an aqueous alkali developer and an aqueous alkaline solution containing or free of organic substances such as organic solvents and/or surfacants. Moreover, when it is used to form PS plates, the resulting lithographic printing plates never cause background contamination and can provide a large number of good printed matters. The composition makes it possible to develop negative working PS plates with developers for positive working PS plates. Therefore, when both positive and negative working PS plates are processed, the use of the composition can save various troubles.
