Title: Tool frame for wafer carrier and wafer shifting device
Inventor: YATABE YASUO
IPC: H01L21/68
Filed: 1988-12-27
Abstract: PURPOSE:To enable a wafer to be surely shifted and eliminate danger of damage in the wafer by providing a second engaging means which should be engaged to a first engaging means provided at a front plate and near the opening at the carrier main unit of a wafer carrier. CONSTITUTION:A cylindrical protrusion 12 which is a second engaging means provided at a front plate 13 of tool frame for wafer carrier is provided at a position which should be engaged to a circular recessed part 11 provided near the opening of the main unit of the wafer carrier. By engaging the cylindrical protrusion 12 to the circular recessed part 11 and mounting a carrier main unit 2 to the tool frame for wafer carrier, the relative position of a shifting unit main unit 20 and a wafer does not change even if a protrusion part 9 at the carrier main unit 2 changes. Thus, when a movable arm 16 is moved toward the carrier main unit 2, the tip of a loading tool 26 does not collide against the wafer 4 and the wafer 4 can be surely shifted.

Title: Memory controller for binary picture data
Inventor: WATAZUMI TERUHIRO
IPC: G06T9/00
Filed: 1988-12-27
Abstract: PURPOSE:To improve the memory efficiency of the picture data by dividing a picture processing system into a process carried out by a run length compression memory system and another process carried out by a bit map memory system based on the input picture data and storing the picture data according to these two modes. CONSTITUTION:A memory 2 stores the data which are read by a picture scanner 1. An 8-bit serial/parallel converter 3 outputs the data which are successively received from the scanner 1 for each picture element every 8 bits and at one time, and a memory controller 4 which processes properly the 8-bit parallel data given from the converter 3 and stores these data into the memory 2. Then the 8-bit picture data are stored by a run length compression memory system when these picture data received in parallel with each other are equal to each other. While a bit map memory system is applied to store the picture data when they are not equal to each other. As a result, the picture data can be stored with extremely high efficiency.
