IPC: H01L21/304
Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To secure a sufficient wiring formation reliability by eliminating steep steps in a process of flattening a layer insulating film based on chemical- mechanical polishing with use of a 2-layer stopper. SOLUTION: A nondoped glass(NSG) film 21 of a low polishing rate is formed to cover a step pattern of gate electrodes 13-1 to 13-3 formed on a silicon-on- insulator(SOI) layer 15-1, 15-2. Further formed on a borophosphosilicate glass(BPSG) film 22 of a high polishing rate, on which an NSG film 23 of a low polishing rate is formed. In this case, the thicknesses of the NSG, BPSG and NSG films 21, 22 and 23 are set so that the highest level surface of the NSG film 21 in a dense pattern region 12 becomes nearly the same as the lowest level surface of the NSG film 23. The laminate is then entirely flattened by the CMP. Therefore, after the CMP process, there remains no steep step in the dense pattern region 12.

Title: Processing circuit at time of reset-key depression
Inventor: NAGAI YASUO
IPC: G06F3/14
Filed: 1978-05-08
Abstract: PURPOSE: To perform processes taking the depression of a reset key and a cursor position into consideration, by distributing status information making a comparison between the contents of registers to which a data-length initial value and a current data length value are set.  
     CONSTITUTION: Once a key-in instruction is sent out, a data length value is set via bus (a) to data-length initial-value setting register 1 and current-data length setting register 2. Then, control key data sent afterwards are set to register 3. When not the data key but the reset key is depressed, data are set to this data register 3 and it is found through the comparison of the comparator circuit that the content of register 1 is equal to that of register 2, so that line (c) will be active through AND gate 6. Further, line (e) is made active through OR gate 8, thereby causing an interruption. With the reset key depressed after the data key, on the other hand, the value of register 1 is greater than that of register 2, so that line (d) will be active through inverter 5 and AND gate 7.

Title: Construction of flow transfer port of purification tank
Inventor: MINOURA HIDEKI
IPC: C02F3/00
Filed: 1979-04-30
Abstract: PURPOSE: To reduce the pressure acting upon partition plates at the cleaning, dipping up, etc. by forming the elastic flow transfer part provided with radial notches to the partition plates which partition aerating chambers and separating chambers.  
     CONSTITUTION: A flow transfer part 5 of an elastic rubber plate or the like provided with radial notches 4 is formed on a partition plate 3 which partitions an aerating chamber and separating chamber at a height about half its water level. When the water levels of the both chambers are equal, the notches 4 is closed to prevent the transfer of sludge. When the level of the separating chamber is higher than that of the aerating chamber, the notches 4 is opened to allow the waste water to transfer from the separating chamber to the aerating chamber. If there is no more pressure difference, the notches 4 resume the original closed state owing to elastic force. Hence, even if dipping-up is done from other one of the both chambers at the time of cleaning and dipping-up, a pressure difference occurs to let the waste water to transfer, thus the exertion of a high water pressure upon the partition plate 3 is obviated.
