Title: Field effect transistor circuit
Inventor: KATSU SHINICHI
IPC: H03K3/356
Filed: 1982-02-16
Abstract: PURPOSE:To realize high-speed operation and low power consumption and to improve operation stability, by using a differential circuit in a latch circuit, and relaxing control over the thickness of an FET active layer. CONSTITUTION:Between a grounding terminal and the cmmon-connected source terminal 3 of input-stage field effect transistors (FET) 1 and 2 of a current switching type logical circuit, a normally-on type single-gate FET5 or dual-gate FET6 is interposed and their gate terminals are connected to the grounding terminal. Characteristic curves (b) and (c) show the voltage-current relations of the single-gate FET5 and dual-gate FET6. The use of the normally-on type FET as a current source improves current stability as compared with a resistance and provides high-speed logical operation with a large noise margin. Further, the use of the normally on-type dual-gate FET6 as the current source provides saturation characteristics superior to those of the single-gate FET5, so higher performance is obtained.

IPC: H04L12/58
Filed: 1992-02-12
Abstract: PURPOSE:To simplify the equipment configuration by using an image processing section only when required so as to decrease number of the image processing section to be less than number of lines. CONSTITUTION:When image conversion (picture size, line density, coding system) is required at the transmission, an image processing section not in use is selected among image processing sections 501-50N, changeover sections A, B are used to connect the image processing sections 501-50N between an image storage section 3 and communication control sections 101-10M to implement the image conversion. When no image conversion is required for the transmission, the image is directly transferred from the image storage section 3 to any of the communication control sections 101-10M. When all the image processing sections are busy for the transmission, the transmission is tried again after a prescribed time. In the case of the reception, each communication control section transfers directly the received image to the storage section 3 without using the image processing section.
