Title: Dpcm device
Inventor: OOKAWA YASUHITO
IPC: H04N7/32
Filed: 1980-09-25
Abstract: PURPOSE:To converge a bias potential produced by transmission error to zero, by making a quantized value to -1 when the difference between an input value and an estimated value is zero. CONSTITUTION:An input value xn is converted into a differential value en between said value xn and an estimated value xn obtained based on a coded value Pn. After the value en is quantized at a quantizer 2, it is coded. As the characteristics of the quantizer 2, the quantized value Qn is assigned to -1 when the valueen is 0. Thus, even if the inversion of bits takes place because of trasnmission error and the data is biased as a decoding side, the biased value is reduced and transmitted with a normal level by transmitting Qn=-1.

Title: Standard cell
Inventor: MATSUMOTO TAKESHI
IPC: H01L21/82
Filed: 1992-04-28
Abstract: PURPOSE:To eliminate parasitic wiring capacity at an unnecessary terminal when routing is made possible from both upper and lower sides in a primitive cell for automatic layout in stardard cell system. CONSTITUTION:Since polysilicon 101 for leading out an input and polysilicon 103 for forming a transistor are formed in different layout layers, excessive routing can be eliminated by detecting the polysilicon for leading out input not contacting with routing data on the profile of a cell upon finish of placement and routing through automatic layout and then deleting the polysilicon thus detected. Consequently, input capacity of cell is reduced. For example, lower polysilicon for leading out input is deleted in the case of routing from upper side whereas upper polysilicon for leading out input is deleted in case of routing from lower side.
