Title: Mobile communication terminal with infrared-ray port
Inventor: OKANO MICHIAKI
IPC: H04B10/11
Filed: 1998-10-08
Abstract: PROBLEM TO BE SOLVED: To continue a communication state and to prevent ineffective communication in a disconnection state by switching the mode to a previously set operation mode, when an infrared-ray interface is disconnected when the voice and data of an external terminal are communicated through an air interface. SOLUTION: When the interception of infrared rays is detected on an infrared-ray link, an alarm sound is sounded from the receiver/loudspeaker of a mobile communication terminal 100 and an alarm message is displayed on an LCD 41. At this time, a VOX procedure from the mobile communication terminal 100 to a network side is started automatically, the voice transfer to an air interface is switched to a VOX ON mode and voice transmission to a communication channel is set to a predetermined soundless pattern. When the infrared-ray link recovers from the interception, the transfer is automatically switched to a VOX OFF mode. Therefore, while the air interface side maintains communication and suppresses transmission power of the air interface which is large in power consumption, even during the period when the infrared-ray link is disconnected.

Title: Bellows having good heat reserving property
Inventor: YAMAMOTO AKIO
IPC: F16L27/12
Filed: 1997-10-20
Abstract: PROBLEM TO BE SOLVED: To remarkably improve the heat reserving property by preventing an inner pipe from directly touching the outside air by making the thermal expansion coefficient of an outer pipe larger than that of the inner pipe in a double-pipe structure bellows equipped with an outer pipe and an inner pipe. SOLUTION: Stainless steel is suitable as a material used for an inner pipe and an outer pipe of a bellows which are different in thermal expansion coefficient, and since the thermal expansion coefficient of the austenite base stainless steel is considerably larger than that of the ferritic stainless steel, the former is used for the outer pipe, and the latter is used for the inner pipe. Accordingly, in the case where high-temperature fluid flows inside the inner pipe, a clearance is produced between both pipes, thereby reducing thermal conduction due to contact so as to obtain heat reserving property. When the inner and outer pipes are fixed at both ends of the bellows and the outer pipe is kept from being extended over the inner pipe in the longitudinal direction, the clearance can be easily further enlarged.  Further, not only the heat reserving property but also the other characteristics can be improved by defining the components of respective stainless steel.
