Abstract: A hermetic compressor includes a compressor shell, a terminal provided on the compressor shell, a terminal guard erected on the compressor shell and surrounding the terminal, and a terminal cover mounted to the terminal guard and covering the terminal. A terminal chamber is defined by the compressor shell, the terminal guard, and the terminal cover. Except for at least a body of the terminal, metal portions facing the terminal chamber are generally covered with an insulator such that the metal portions are not exposed to the terminal chamber. The insulator includes an insulating portion that covers an inner surface of the terminal guard.

Abstract: A compressor (10) includes a casing (20), a terminal (29) protruding from the casing, a first cover (70) covering the terminal, and a second cover (50) covering the first cover.

Abstract: An on-board update device and an on-board update system provided herein may prevent a decrease in the electric power charged in the battery caused by an update. An on-board update device has an update processing unit configured to update a program stored in a storage unit of a communication device. The on-board update device includes: an update information acquisition unit; a required electric power estimation unit; and a battery level acquisition unit acquires an amount of electric power charged in the battery. The update processing unit performs an update process in consideration of the amount of electric power estimated by the required electric power estimation unit, the amount of electric power acquired by the battery level acquisition unit, and a priority level of the update program or data acquired by the update information acquisition unit.

Abstract: A scroll compressor includes a fixed scroll, an orbiting scroll and an injection passage. Each scroll has an end plate and a spiral lap. The scrolls mesh with each other to form a compression chamber. The injection passage supplies intermediate pressure refrigerant and refrigeration oil separated from discharged refrigerant to the compression chamber. At least one of the scrolls has a bottom land facing the lap of the other of the scrolls. The bottom land has an intermediate bottom region facing a part of the compression chamber communicating with the injection passage, and a suction side bottom region located closer to an outer end of the lap than the intermediate bottom region. A clearance between the suction side bottom region and the end face of the lap is larger than a clearance between the intermediate bottom region and the end face of the lap.

Abstract: A floor covering peeling motor-powered vehicle having a peeling blade movable back and forth by means of a thrusting device at a specified angle relative to the floor surface, such that the cutting edge of the peeling blade is advanced into a space between the floor surface and the floor covering under a specified thrust force while the vehicle is in motion, whereby the floor covering can be easily and quickly peeled from the floor surface.
