According to one embodiment, an electronic apparatus includes a first module and a second module. The first module receives a remote command from another electronic apparatus and transmits a response to the remote command to the other electronic apparatus. The remote command includes command type information indicating a type of the local command. The second module issues one or more local commands including the local command to the storage device and transmits a first response from the storage device to the other electronic apparatus by storing the first response into a second response to the remote command, in accordance with a process specified by the command type information in the remote command.
摘要:
Dissimilar metal welds including a buttering portion with a small variation in strength distribution in a plate thickness direction are formed by welding two parent materials having at least one of different compositions and different refining conditions through a buttering for alleviating mismatch between one of the different compositions and the different refining conditions of the two members and through a welded metal for joining one of the parent materials and the buttering. The buttering is formed of welding metals laminated in a plate thickness direction, and a dilution ratio of the buttering with the parent materials is 50% or less. The manufacturing method includes performing butt welding on a dummy material formed by increasing a groove depth by providing a member on a bottom side of a welding groove and on parent materials by using the buttering; and processing a groove within a welding metal formed of the buttering.

A hermetic compressor includes a hermetic container, a motor element, and a compression element. A shaft of the compression element includes a main shaft, a flange projecting from the main shaft, and an eccentric shaft connected to the flange. A main bearing has a thrust surface contacting and sliding on the flange of the shaft. The thrust surface consists of a first portion and a second portion. The first portion is farther from the compression chamber than the center axis is. The second portion is closer to the compression chamber than the center axis is. The area of the first portion is larger than the area of the second portion. This hermetic compressor has a high efficiency and a high reliability.
摘要:
In the electronic equipment of the present application, a center axis of a cylindrical portion 11a of a shaft 11 is eccentric with respect to a rotation center axis of the shaft 11, whereby even when a cable 21 comes closest to the shaft 11 in the turning of a first housing 1 or second housing 2, a sufficient space can be secured between the shaft 11 and the cable 21. Thus, in a turning range of the first housing 1 or second housing 2, it is highly unlikely that the shaft 11 and the cable 21 come into contact with each other, which avoids an increase in a tension of the cable 21 and wear on an insulation cover of the cable 21. By avoiding the increase in the tension of the cable 21, breakage of the electric wires in the cable 21 can be avoided.
