Abstract: 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.

Abstract: A communication terminal unit has a system control section including a communication error detection section that detects a communication error, which occurs at the time of originating a call over an IP network or a public network. A communication error analysis section analyzes the thus-detected communication error, and in accordance with the result of analysis of the communication error, a call origination network determination section automatically determines whether to re-dial a call over the IP network or the public network. As a result, when detecting a communication error at the time of origination of a call over the IP network or the public network, a system control section performs control operation for analyzing the communication error and automatically determining whether to re-dial a call over the IP network or over the public network.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: In a facsimile communication method, when a home facsimile machine makes the transition to simplified protocol phase B because of sensing polarity inversion, CED reception from an associated machine, etc., it stores 9600 bps as the initial value of control signal communication speed and sends a communication speed notification signal of the frequency corresponding to the stored communication speed to the associated machine, then sends an NSS thereto at the stored communication speed. When receiving the communication speed notification signal, the associated machine previously senses execution of the simplified protocol and the communication speed of the subsequently received NSS from the notification signal and receives the NSS at the sensed communication speed, then sends a communication speed notification signal of the frequency corresponding to the sensed communication speed and subsequently sends an NSF at the communication speed.
