IPC: H03K5/08
Filed: 1978-11-24
Abstract: PURPOSE:To eliminate noise without generating a time delay between the input and the output by supplying simultaneously regular signals and signals, which are obtained by delaying them by a prescribed time, as the input of a logical operation circuit. CONSTITUTION:Digital signals are supplied to signal input terminal 1, and these signals are supplied to not only one input terminal 8 of AND circuit 7 but also the other input terminal of AND circuit 7 through high-band stop filter 10. High-band stop filter 10 consists of resistance 13 and capacitor 14 and eliminates the high- frequency noise of digital signals. When the output of filter 10 exceeds the threshold level of AND circuit 7, AND is operated in AND circuit 7. No AND output is generated for the pulse noise having a period smaller than time t1 when the output of filter 10 reaches the threshold level.

Abstract: PURPOSE: To lower the temperature of cooling sea water that is released into the sea by providing a first heat exchanger, which cools a steam turbine exhaust, to an exhaust steam system for a steam turbine, which enters a condenser, and providing a second heat exchanger, which cools cooling drain, to a drain system for a condenser cooling water, which comes out of the condenser. CONSTITUTION: A seawater cooler 6 is a heat exchanger in which the sea water, which acted as cooling water for a condenser (S) an, as a result, whose temperature was raised, makes a heat exchange with liquid air (L). A fuel preheater 7 is a heat exchanger in which exhaust steam from a steam turbine ST makes a heat exchange with fuel (F) to preheat a boiler fuel and which recovers the waste heat from the condenser (S). Since the sea water, which was drawn up from an intake 2 in the sea water (1) by using a sea water pump P2, is used in the condenser (S) for cooling, the temperature of the sea water as cooling water rises. This sea water goes through a sea water cooler 6 to make a heat exchange with the liquid air (L), thereby lowering the temperature. After this, the sea water is released via a bleedoff port 3.  With this contrivance, a load to the condenser (S) can be reduced by the first heat exchanger 6, while the temperature of the cooling sea water to be released into the sea is lowered by the second heat exchanger 6, thereby preventing the breeding of jellyfish.

Abstract: PURPOSE:To present the malfunctions of a 2-bank memory DBM including two RAMs which are never simultaneously set in the write modes end to improve the operating speed of a computer including the 2-bank memory DBM by preventing the malfunctions of the computer. CONSTITUTION:The write pulse generating circuits WPG1 and WPG2 are provided in a 2-bank memory DBM to produce a prescribed internal signal WG1* or WG2* for production of a write pulse WP1 or WP2 based on the clock signals KO1, KO and K1 and supply the WG1* or WG2* to a RAM 1 or RAM2. Thus both signals WG1* and WG2* can be produced independently and for each RAM and with the cycles shifted from each other. Therefore the cycle time is extremely shortened. Then it is possible to produce such a write pulse that can satisfy the prescribed timing conditions even when the cycle time is approximate to the width needed for each write pulse. In such a constitution, the malfunctions of a multi-bank memory can be prevented.

Title: Two-wire type switchgear and its power circuit
Inventor: FUNAKI MASAO
IPC: H01H9/54
Filed: 1989-06-12
Abstract: PURPOSE:To make a switch achievable at a rate of low power consumption by connecting the gate of a triac to one of the a.c. input terminals of a diode bridge via a break and make contact, and then taking out a d.c. voltage from each of the d.c. output terminals of the diode bridge. CONSTITUTION:While a latching relay is in its reset condition, a contact S being turned on by excitation of a set coil Rs is in the position of break and consequently no current flows through the gate of a triac T connected in series to both an a.c. supply 1 and a load 2, so that the triac T is kept in its off condition. Although the load 2 on the other hand is set in the condition of lights-out since a current whose level is set to such an extent that a resistor R2 connected in series to a diode bridge REC input refuses the load 2 to be operated flows between the a.c. input terminals of the diode bridge REC, a full wave-rectified constant voltage is generated across a constant voltage diode ZD connected between the d.c. output terminals of the diode bridge REC. For this reason, the switchgear in the title hardly consumes power in its normal condition, thereby obtaining specified power only when an operating switch is operated.
