Filed: 1988-09-20
Abstract: PURPOSE:To improve a manufacturing efficiency by a method wherein a mask in which all the contact holes which can be formed are lithographed and a mask in which only the contact holes necessary to realize circuit functions are lithographed are put together and only one of them is replaced. CONSTITUTION:A mask pattern (a) formed by lithographing all the contact holes of the foundation pattern of an object LSI with a required accuracy and a mask pattern (b) formed by lithographing the contacts necessary to realize required circuit functions are formed and the mask patterns (a) and (b) are combined to form a complete mask pattern (c). Therefore, if the mask (b) is replaced in accordance with types while the mask (a) is attached to a contracting projection aligner for a necessary period, a necessary pattern can be obtained. Moreover, as the dimensional accuracy of the mask (b) is rough, highly accurate mask alignment is not necessary. With this constitution, the manufacturing efficiency can be improved.

Filed: 1998-08-24
Abstract: PROBLEM TO BE SOLVED: To easily conduct line number conversion and format conversion with a simple configuration. SOLUTION: A signal in the 4:2:2 format is inputted to a linear interpolation section 32. A luminance signal DYc and a color difference signal DCc for one line are written in memories 321 and 341 and signals Dyc and DCc for a succeeding line are written in memories 322 and 342. Similarly, signals are alternately written. The signal Dyc are read twice from, e.g. the memories 321, 341 for a signal write period for one line, coefficients KY1, KY2 for linear interpolation are multiplied with the obtained signal and the products are summed to generate a luminance signal Dyd. In the case of reading the signal Dyc twice, the signal DCc is read once from the memories 322, 342, coefficients KC1, KC2 are multiplied with the signal and the products are summed to generate a color difference signal DCd.  The interpolation control section 36 applies write read control of the signal to the memories and conducts coefficient setting.

Title: Faulty environment supervisory system
Inventor: KIMURA TETSUO
IPC: H04Q9/00
Filed: 1997-08-20
Abstract: PROBLEM TO BE SOLVED: To provide the faulty environment supervisory system where a central supervisory controller easily detects a duplicate address independently of an output of a terminal even on the occurrence of a state of duplicate address setting. SOLUTION: A polling address is set (S2), a terminal equipment compares a received address with its own address and a comparison result is outputted to a command identification device. Then a command to check a duplicate address is transmitted (S3), the command is analyzed by a command identification device, a characteristic value read instruction is made to a characteristic value setting section from the command identification device from the result and the read characteristic value is read by a central supervisory controller as a return signal (S4).  On the occurrence of a duplicate address at the central supervisory controller, since characteristic values are almost simultaneously returned from plural terminals, a parity check or the like for the return signals indicates reception of abnormal return signals at a transmission check section in the central supervisory controller, then the central supervisory controller discriminates it that a duplicate address takes place in the terminals.
