摘要:
A refrigerant compressor having a compression element comprising sliding components made of metallic materials, wherein a mixed layer is formed by solid-dissolving molybdenum disulfide in at least one of the sliding faces of the sliding components, and a single molybdenum disulfide layer is further formed on the surface of the mixed layer. With this configuration, initial break-in is done using the single layer, and sliding loss is reduced. Even if the single layer peels off, because the molybdenum disulfide of the mixed layer is cleaved at a low friction coefficient, solid lubrication action is attained, the friction coefficient of the sliding section is lowered, and sliding loss is reduced.
摘要:
A highly reliable sliding face modification material capable of forming a stable film of molybdenum disulfide on the sliding face of a sliding member, the sliding face modification material having a molybdenum disulfide content of 95 wt % or more and an organic material content of 1500 ppm or less in weight ratio, and the sliding face modification material being projected onto the sliding face to form a coating layer.

A refrigerant compressor includes a compressor section, driver, a first contact section and a second contact section. The compressor section is accommodated in a closed container for compressing refrigerant gas. The driver drives the compressor section. The first and second contact sections are brought into contact with each other or they slide with each other by driving the compressor section. On the surface of each one of the contact sections, at least one of plural recesses uniformly placed or a mixed layer, to which molybdenum disulfide (MoS2) is bound, is formed. The foregoing structure allows increasing the abrasion resistance of the first and second contact sections.

摘要:
A communication terminal that includes a first communication unit that is coupled to an IP (Internet Protocol) network and conducts a facsimile transmission through the IP network; a second communication unit that is coupled to a public telephone network and conducts a facsimile transmission through the public telephone network; a control unit that, in a case that a communication error is detected when the first communication unit calls to the IP network and that the address information used for calling to the IP network is the address information corresponding to the destination which is converted from the telephone number received by a reception unit, controls the second communication to call to public telephone network by using the telephone number received by a reception unit.
摘要:
The present invention provides a refrigerant compressor which may assure excellent reliability while using low-viscosity refrigerant. The refrigerant compressor is characterized in that the viscosity of oil stored in hermetic container ranges from VG3 to VG8, and the boiling component at 350 C or over is not less than 10% and not higher than 30% in volume ratio, and the boiling component at 300 C or less is not less than 50% and not higher than 70% in volume ratio. Accordingly, the input reduction at sliding surfaces can be realized, and the lubricant is evaporated, therefore it is possible to prevent defective compression caused by PET (polyethylene phthalate) or the like deposited on the surfaces of the discharge reed and the like, and to enhance the efficiency and reliability.

摘要:
A communication terminal unit has a system control section including a call destination specification information analysis section that analyzes a destination number which is assigned to a communications terminal unit at the other end and input at the time of origination of a call. On the basis of a result of analysis of the destination number performed by the call destination specification information analysis section, a call origination network determination section automatically determines to originate a call over an IP network or over a public network through use of the destination information that has been subjected to analysis and through use of selected network setting information stored in a selected network setting storage section. Selected network setting information required to automatically determine to originate a call over the IP network or over the public network is stored in the call origination network determination section.

摘要:
An image communication apparatus comprises: a call connection control unit that establishes a session with a communication partner using an SIP message; and an image communication control unit that controls an image communication, wherein (i) when the call connection control unit receives, as a calling party, from a called party, an INVITE SIP message in which a T.38 communication and a first priority transport are specified in a session description protocol, and when a second priority transport is set in the image communication apparatus of the calling party, the call connection control unit opens the second priority transport, and (ii) when no priority transport is set in the image communication apparatus of the calling party, the call connection control unit opens the first priority transport specified by the called party, and performs a T.38 communication using the opened transport.
