20080270045 | FLOW RATE MEASUREMENT DEVICE - A flow rate measurement device ( | 10-30-2008 |
20090240444 | FLOW RATE MEASUREMENT DEVICE - The present invention provides a flow rate measurement device for measuring a volume of gas flowing through a gas supply system in which a plurality of appliances are connected. The flow rate measurement device according to the second embodiment comprises a flow rate sensor configured to detect a gas flow flowing through the gas supply system and a differentiator configured to differentiate the detected gas flow. A memory is provided in which profiles of gas consumption by appliances are storable in relation to identities of the appliances. The flow rate measurement device according to the present invention also comprises a first profile finder which is responsive to the differentiated gas flow to search for a profile from the stored profiles which corresponds to the detected gas flow. The device further comprises a second profile finder which is responsive to a failure by the first profile finder to find the corresponding profile from the stored profiles to analyze the detected gas flow to thereby determine an identity of at least one of the plurality of appliances. | 09-24-2009 |
20090240445 | FLOW RATE MEASURING DEVICE, AND GAS SUPPLY SYSTEM EMPLOYING IT, METHOD FOR SPECIFYING GAS APPLIANCE - A flow rate measuring device has a flow rate measurement unit, an appliance registering unit, a calculating unit, a determining unit, a first appliance identifying unit, and a second appliance identifying unit. The appliance registering unit stores at least first gas flow rate variation profiles on activation of respective gas appliances coupled to a flow channel, and second gas flow rate variation profiles based on the control specific to the respective gas appliances. The first appliance identifying unit identifies which gas appliance is activated based on the first gas flow rate variation profiles on activation. When a determining unit detects a stop of any of gas appliances, the second appliance identifying unit identifies a gas appliance in continuous use by using the second gas flow rate variation profiles based on the control specific to the respective gas appliances. | 09-24-2009 |
20100017150 | FLOW MEASUREMENT APPARATUS AND PROGRAM THEREOF, FLOW MEASUREMENT METHOD AND FLUID SUPPLY SYSTEM - A fluid measurement apparatus capable of accurately determining an activated appliance is provided. A flow measurement apparatus | 01-21-2010 |
20100326548 | FLOW RATE MEASUREMENT APPARATUS AND GAS SUPPLY SYSTEM - If determination is erroneous in appliance determination according to the instantaneous flow rate output from a flow rate measurement unit, a flow rate measurement apparatus registers it as an unknown appliance, rechecks the flow rate of the unknown appliance, and makes it possible to enhance the accuracy of the appliance determination. The apparatus has a flow rate measurement unit | 12-30-2010 |
20110036544 | HEAT EXCHANGER - A heat exchanger comprises a substantially pillar sheathed heater, a substantially cylindrical case, and a spiral spring. The sheathed heater is accommodated in the case. The spring is provided so as to be wound around an outer peripheral surface of the sheathed heater. Thus, a spiral flow path is formed among an outer peripheral surface of the sheathed heater, an inner peripheral surface of the case, and the spring. The spring functions as a flow velocity conversion mechanism, a turbulent flow generation mechanism, a flow direction conversion mechanism, and an impurity removal mechanism. A water inlet and a water outlet are respectively arranged at positions eccentric from a central axis of the case on a side surface of the case. | 02-17-2011 |
20120234179 | DUST COLLECTING SYSTEM - An indoor dust collecting system includes an air conditioner having an indoor unit that generates an air current, a dust collector, and a controller for controlling the air current from the indoor unit. A moving body detector is provided to detect a moving body such as, for example, a person, a pet, a cleaning robot, and the like. The air current from the indoor unit is controlled by the controller based on the position of the indoor unit, the position of a spot of occurrence of dust detected by the moving body detector, and the position of the dust collector such that the air current from the indoor unit reaches the dust collector via the spot of occurrence of dust in order for the dust collector to effectively suck the dust. | 09-20-2012 |
