Patent JP-S5821379-A (JP)
Title: Field-effect transistor
Inventor: KOBAYASHI DAISAKU
IPC: H01L21/337
Filed: 1981-07-29
Abstract: PURPOSE:To obtain a FET having high gains and high gm by forming source and drain regions while being contacted with an insulating layer with predetermined depth on an N type Si layer and shaping a gate region between both regions. CONSTITUTION:A P layer 3 is formed to a section, which is held by a SiO2 layer 2 having a predetermined space, of an N type substrate 1. The mutually parallel gate layer 4, source layer 5 and drain layer 6 are striately shaped to the P layer 3 while being contacted with the SiO2 layer 2. Gate wiring 7 is positioned onto the SiO2 2 and connects a pluraity of the gate layers 4, and a source electrode 8 connects the source layers 5. The P layer 3 is formed in thickness deeper than the insulating layer 2 and the gate, source and drain layers 4-6 in thickness shallower than the insulating layer 2. According to this constitution, wiring capacitance is extremely small because gate width increases equivalently by a plurality of the gate layers and the gate wiring 7 is positioned onto the SiO2 layer 2. Consequently, power gains and gm can be augmented only by enlarging the gate width.

Title: Display device for response time of multicomputer system
Inventor: OOMINATO KOUJI
IPC: G06F15/177
Filed: 1981-07-29
Abstract: PURPOSE:To reduce the load individual computers and guide the operator in respect to the transition of the response time of each computer, by providing one monitoring computer, which measures the response time of each computer, in the multicomputer system. CONSTITUTION:A clock 17 supplies the time signal to CPUs 14 in parallel, and the signal output time point and the signal input time point in a CPU 18 are matched to each other. When the execution request of a task is generated, each CPU 14 sets the signal of logical ''1'' to this task 15 during the time from the start indication to the execution indication and transmits this signal to the CPU 18 through a process input/output device 16. Tasks 15 are divided to about 16 levels in the whole of the multicomputer system and are transmitted to the CPU 18 in time division. Sixteen kinds of level signal are transmitted from respective tasks 15, which are divided to 16 levels, repeatedly in every time frame. If the task is not within a response time, the signal is set to logical ''0''. Response times for respective levels are measured and stored and are displayed 19 on a display and are printed 20 on a printer 20 in time series, thus reporting them to the operator.

Title: Reference voltage generating circuit
Inventor: SAKAGUCHI JIROU
IPC: H01L27/088
Filed: 1981-07-31
Abstract: PURPOSE:To generate a reference voltage stably against power voltage variation  and temperature variation by canceling temperature characteristics of the difference in threshold voltage between a couple of FETs, differing in threshold  voltage, by temperature characteristics of the threshold voltage of FETs of a  bias circuit. CONSTITUTION:A poly-Si layer as the gate electrode of an n channel insulator gate MISFETQ1 is principally a p<+> type. Poly-Si layers as gate electrodes of MISFETs Q2 and Q3 are n<+> types. Therefore, the threshold voltage Vth1 of the FETQ1 is higher than the threshold voltage of the FETQ2 because of the difference in conduction type between the gate electrodes. For this purpose, the current multiplication factor of the current mirror circuit composed of MISFETs Q4 and Q5 is set to 1 and the FETs Q1 and Q2 are equalized in size to obtain an  output voltage Vref=vth1-Vth2. Consequently, the voltage Vref depends upon the  sizes and threshold values of the respective FETs and does not depend upon a  power voltage, and excellent temperature characteristics determined by the difference between both threshold values are obtained.
