Title: Semiconductor integrated circuit
Inventor: NISHIZAWA JIYUNICHI
IPC: H01L27/06
Filed: 1983-03-12
Abstract: PURPOSE:To contrive to reduce the capacity in the periphery of gates and thus keep a high integration density by a method wherein a region of low impurity density wherein gates are formed is allowed to have a stepwise or gentle distribution of densities, then the density of surface side is enhanced, and an interval between gates is narrowed, then an intrinsic or low density layer is provided under the gates. CONSTITUTION:An N<+> layer 12 buried in a P type substrate 104 and an electrode 1 of MIS structure on the surface form an XY matrix. Writing, accumulation and reading are performed by the voltage control for the electrodes 1 and 12, or the P-layer 104. In the presence of N<-> layers 13, the potential of diffusion can be enhanced, thus the leakage at the time of accumulation can be reduced. In the presence of an N<--> layer or an I-layer 113, the capacity can be reduced, and therefore high speed wiring and reading are enabled, and the integration degree of a memory device can be improved. It is preferred that the impurity density is set at 10<17>/cm<3> or less in the layers 13, then the thickness is selected according to purposes, and the density is set at 10<15>/cm<3> or less in the layer 113.

Abstract: PURPOSE:To perform suitable exhaust gas recirculation (EGR) in proper quantities by determining an engine load in starting EGR according to engine cooling water temperature, and controlling an EGR device so that EGR may be performed when the engine load is above the engine load. CONSTITUTION:During the operation of an internal combustion engine 1, when cooling water temperature obtained by a water temperature sensor 52 is above the first fixed value, a decision is given on whether the cooling water temperature is higher than the second fixed value (>the first fixed value) or not.

Title: Actuator testing equipment
Inventor: MATSUBARA TAKEHIRO
IPC: G01R31/50
Filed: 1981-03-17
Abstract: PURPOSE:To test the indefectibility of a driving circuit including an actuator, by flowing the current of such level that the actuator does not come into the actual operation or reducing the current to such level that the actuator does not come into the actual stop in course of the operation of a plant. CONSTITUTION:In the normal state, since a contact 1 is turned off, an actuator 10 is not operated. When the output resistance of a variable resistance circuit 24 is reduced to start flowing a current to a light emitting diode of a photocoupler 21, a power transistor 25 becomes conductive, and the current flowing to the actuator is started. This current flowed to the actuator is detected by a current pickup 26 while feeding back the current value to the variable resistance circuit 24 to control the current so that this current does not become larger than the operating current, and the indefectibility of the actuator circuit is discriminated by a discriminating circuit 27. Thus, there is no probability of erroneous operations, and a high-reliability testing equipment is obained because it is unnecessary to use a movable contact in the actuator circuit.
