Title: Decoder circuit
Inventor: IWASAKI TOMONOBU
IPC: G11C8/10
Filed: 1988-02-02
Abstract: PURPOSE:To surely set a decoder circuit to a selecting state without using any timing signal when the circuit is set to the decoding operations by causing the gate-source voltage to exceed a threshold only in an MIS transistor whose gate electrode is connected with an output signal line for maintaining pre- charging potential. CONSTITUTION:Output terminals of output signal lines X0-X7 are respectively connected with gates of transistors T0-T7 (n-channel MIS transistors) which are provided in corresponding to the signal lines X0-X7 and sources of the transistors T0-T7 are connected with adjacent output signal lines. In the case of the transistor T0, for example, its source is connected with the adjacent output signal line X1. A dummy line DL becomes low in level regardless of address signals A0-A2 at the time of decoding operations and is required for turning on the transistor T7 when the output signal line X7 is selected. When such constitution is used, only the transistor (one of the transistors T0-T7) with the gate, to which a selected output signal line (H-level) is connected, is turned on and at the other transistors with gates, to which nonselected signal lines are connected, both the gates and sources become low in level and the transistors are not turned on.

Title: Production of plated member for welding
Inventor: NAGAYAMA SEIICHI
IPC: C23C2/02
Filed: 1993-02-10
Abstract: PURPOSE:To prevent the formation of a galvanizing film at the ends of an iron cylindrical material by utilizing a masking material consisting of the iron oxide film at the ends or plastics at the time of galvanizing the iron cylindrical material exclusive of its end. CONSTITUTION:The oxide film which hinders the formation of a plating film exists over the entire part of the iron cylindrical blank material at the time of galvanizing the entire surface of the iron cylindrical blank material exclusive of the weld zone at its ends and, therefore, the masking member is applied to the welded end where the plating is not required and thereafter, the oxide of the part to be plated exclusive of the ends is removed by a pickling treatment. After the material is subjected to a flux treatment, the masking material at the ends is removed and the material is immersed into a galvanizing bath. Since the oxide film remains at the ends without being pickled, the galvanized material having the ends remaining without being plated is obtd. The ends where the plating is not required are otherwise subjected to a molten masking treatment by plastic powder and thereafter, the material is subjected to the flux treatment and is immersed into the galvanizing bath, by which the galvanized cylindrical material having the non-plated parts at the ends is produced.

In the ECU 49, when the starting time of a diesel engine 1 is judged on the basis of the signals of a starter switch 47 and an ignition switch 48, learning of detected atmospheric pressure is started so as to decide learning atmospheric pressure. In the ECU 49, after completion of learning is judged, learning atmospheric pressure which is decided by learning is memorized in a memory as the newest data to be referred to for the purpose of converting the relative controlled negative pressure.
