Publication number: 20190063811Abstract: Provided are an ice making device and a method of inspecting the same. In the ice making device, signal lines extending from a temperature sensor are connected to a drive unit. The drive unit performs an ice removal process of removing ice from an ice making tray when a temperature detected by the temperature sensor is equal to or lower than a set temperature.

Patent number: 9631559Abstract: A fuel control method for a gas turbine with a combustor being formed of at least two groups of a pluralities of main nozzles for supplying fuel, and that supplies fuel from the main nozzles of all groups upon ignition of the combustor (S1), and supplies fuel from three main nozzles of a group A during subsequent acceleration of the gas turbine (S3). Because fuel is injected from a small number of the main nozzles during acceleration, the fuel flow rate per one main nozzle is increased, thereby increasing the fuel-air ratio (fuel flow rate/air flow rate) in a combustion region and improving the combustion characteristics. Accordingly, the generation of carbon monoxide and unburned hydrocarbon is reduced, whereby no bypass valve is required and manufacturing costs are reduced.Type: GrantFiled: March 10, 2014Date of Patent: April 25, 2017Assignee: MITSUBISHI HITACHI POWER SYSTEMS, LTD.Inventors: Sosuke Nakamura, Satoshi Tanimura, Shinji Akamatsu, Shinsuke Nakamura, Takashi Sonoda, Akihiko Saito, Makoto Kishi
