Abstract: A method of recovery from occurrence of an abnormal state during a handsfree phone speech is provided which is capable of improving safety such as driving safty. When an abnormality in communications occurs in a short-distance wireless communication line between a handsfree unit and a mobile phone unit, the communication abnormality is detected by a mobile phone unit controller in the mobile phone unit. The mobile phone unit controller performs restoration and/or emergency measures including re-connection of a short-distance wireless communication line with the handsfree unit and of a communication line with a telephone set of a party on the other end of a phone over a telephone network.

Abstract: A system for carrying out authentication in settlement account in electronic commerce as to whether a user is really the person himself/herself, includes (a) an authentication unit for carrying out authentication in settlement account, (b) a mobile key unit having a short-distance radio-signal communication unit, and (c) a mobile terminal which, on receipt of a request of carrying out authentication from the authentication unit, transmits a request to the mobile key unit to make communication by transmitting radio-signals to the mobile key unit, and transmits a response to the authentication unit, based on information stored therein, if data relating to the mobile key unit with which the mobile terminal was successful in making radio-signal communication is coincident with data in advance stored in the mobile terminal.

Abstract: A terminal-associated device is combined with a terminal device that is to be protected against unauthorized use, and a key device is carried by the user. The terminal-associated device has a memory for storing information of the key device. When the user who is carrying the key device moves away from the terminal device combined with the terminal-associated device until the terminal-associated device and the key device are no longer capable of connecting to each other based on a short-range radio communication technique such as Bluetooth, radio LAN, or the like, the terminal-associated device locks the terminal device against use.

Abstract: The present invention provides an accumulator 21 for evaporating and condensing a refrigerant in a pressure vessel 22 thereof to control pressure or the like in a closed-loop type controlled unit. The accumulator comprises liquid-phase refrigerant holding means 23 for holding the refrigerant in liquid phase, heating means 25 for heating and evaporating the refrigerant in liquid-phase, cooling means 24 for cooling and condensing the refrigerant in vapor-phase, and a connection port 28 in fluid communication with the controlled unit. The liquid-phase refrigerant holding means 23 includes a vane 32 made of a material capable of absorbing the refrigerant in liquid phase, and the end 35 of the vane 32 has a shape in contact with the inner surface of the pressure vessel 22.

Abstract: A crystalline L-alpha-aspartyl-L-phenyl-alanine methyl ester product is disclosed. The product is obtained by crystallizing the ester from an aqueous solution, by cooling. The initial concentration of ester in the aqueous solution used provides at least 10 grams of precipitated solid phase per liter of solution. The solution is cooled through conductive heat transfer without effecting forced flow to form a sherbet-like pseudo solid phase.

Abstract: A crystalline L-.alpha.-aspartyl-L-phenylalanine methyl ester product and the process for obtaining the same are disclosed. This product is obtained by adjusting the initial concentration of L-.alpha.-aspartyl-L-phenylalanine methyl ester in an aqueous solution so that the amount of precipitated solid, formed after cooling said solution, is about 10 grams or more of precipitate per liter of solvent. The solution is then cooled through conductive heat transfer, without causing forced flow, to obtain a sherbet-like pseudo solid phase.
