IPC: F04B23/00
Filed: 1981-03-31
Abstract: PURPOSE:To prevent corrosion of the lubricating water system by allowing the seawater as bearing lubricating water to be automatically substituted fresh water when pump operation stops, in the case where the self-pressre seawater is used as the bearing lubricating water for the sea-water pump in a thermoelectric power station etc. CONSTITUTION:A pump 1 is driven by a motor 2, and a part of the discharged pressure seawater is supplied as the lubricating water into the bearing part, passing through filtering apparatuses 4 and 5 and an automatic stopper valve 11. As the self pressure water does not exist before a pump starts, fresh water is supplied as the lubricating water by the fresh water feeding system 8. Therefore, the lubricating water flow-rate detection switch 9 and a fresh water substituting vale 12 are installed as shown in the figure. When pump operation stops, a  valve 10 is opened by the signal from the switch 9, then a valve 12 is opened,  and the valve 11 is closed, then the seawater staying in the lubricating water  supply system is substituted by fresh water, and thus corrosion of the lubricating water system due to still seawater can be prevented.

Title: Chopper type dc-dc converter
Inventor: NAKAMURA MANTARO
IPC: H02M3/155
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To reduce switching loss and surge voltage by turning off a switching element thereby discharging a first capacitor for resonance and charging a second capacitor for resonance in sine wave, and turning on it thereby discharging the second capacitor for resonance thereby letting a resonance current flow to the switching element. SOLUTION: While a transistor (switching element) 2 is on, a current 1 flows to load 6 through a transistor 2, a reactor 10 for resonance, and a reactor 4 so as to charge a first capacitor 8 for resonance to the voltage E of DC power source 1. When the transistor 2 turns from ON condition to OFF condition, electricity is discharged to the side of load 6 through the reactor 4 from the first capacitor 8 for resonance, and the second capacitor 14 for resonance is charged from 0V to sine waveform. Hereby, zero voltage and zero current switching is achieved at OFF and ON of the transistor 2, so surge voltage, surge currents, and noise can be reduced, reducing the switching loss of the transistor 2.

Abstract: PROBLEM TO BE SOLVED: To obtain a telephone set supporting a 'plug and play' function, which communicates with the other end point of a telephone system to automatically constitute itself, by providing the telephone set for supporting a plug and play function within the telephone system. SOLUTION: Telephone sets 15-1 to 15-N and a telephone adaptor 20 communicate with each other by using a 'peer to peer' protocol on a control channel. In other words, centralized processing point, namely a central control point, does not exist. Each telephone and/or attached equipment is provided with its own call processing software. A telephone system 10 is capable of constituting itself and this means that each telephone set and/or attached equipment compete with each other concerning the usage of system resources. As a result, the system 10 provides the plug and play function. As one example of the system resources, an intercom number, a voice channel, line wire access, etc., exist.

Title: Blow-by gas introducing device for internal combustion engine
Inventor: FUJIEDA YASUO
IPC: F01M13/00
Filed: 1980-04-09
Abstract: PURPOSE:To prevent an error of operation of a flow control valve in a blow-by gas recirculting passage due to any leak from a temperature responsive valve provided in a suction negative pressure transmitting passage for the flow control valve by disposing a leak means in the negative pressure transmitting passage between both valves. CONSTITUTION:In an idling or a low load range, since a port 31 is located on the upstream side of a throttle valve 17 and hence is not acted upon by negative pressure, a flow control valve 21 in a blow-by gas recirculating passage 20 is held in its closed position. Thus, even if the throttle valve 17 is then opened so that the port 31 is acted upon by negative pressure, a temperature responsive valve 32 is held closed while the engine remains at a low temperature so that the valve 21 is still maintained in its closed position. If, at this instant, negative pressure of a negative pressure transmitting passage 29 rises due to any leak from the temperature responsive valve 32 in its closed position, atmospheric air is leaked little by little from a leak passage 41 which has an orifice 42 therein thereby to inhibit rise of the negative pressure. By this constitution, an error of operation of the flow control  valve 21 is prevented assuredly.
