The rate of decrease of an oxidation suppressing element in a solder bath is measured during a soldering operation. Soldering is then carried out while replenishing the solder bath is then replenished during soldering so as to maintain the surface level of molten solder in the bath with a replenishment solder alloy which supplies the oxidation suppressing element to the solder bath at at least the rate at which the oxidation suppressing element is consumed during soldering. When the oxidation suppressing element is P, the concentration of P in the replenishment solder alloy is preferably 60-100 ppm.

Method of replenishing an oxidation suppressing element in a solder bath

There is provided a portable terminal device which is capable of transmitting and receiving data such as an image during a voice call by using a radio communications system allowing parallel access. The portable access allows parallel access where a voice call by way of a circuit switching system and data communications using a packet communications system are made in parallel. In case an instruction to transmit data to a distant party is issued by way of an operation on the key operation section during a voice call (S), the directory data is referenced and the mail address of the distant party is retrieved and acquired (step S). An electronic mail with the photo image data, etc. shot with a camera section attached is automatically generated and transmitted to the distant party by way of packet communications (S). In case the received electronic mail is from the distant party and image data, etc. is attached, the receiving party opens the data and displays the data on the display section on a priority basis.

In a ringing-tone control device for a telephone set, an audio signal which is sent from a communication opposite party is converted into a corresponding bi-level signal. The bi-level signal is stored into the memory. The bi-level signal is read out from the memory. A ringing tone is generated in response to the bi-level signal read out from the memory.
