Abstract: PURPOSE:To make it possible to prevent a short-circuit between terminals from generating due to a fused solder even in case an abnormal heat generation is generated at the time of use and a solder is fused by a method wherein a thermosetting resin is left to stand until the peripheries of the terminals of a chip carrier are completely covered with the resin, and thereafter, the thermosetting resin is heated and cured. CONSTITUTION:An insulating substrate 1 consisting of ceramic or the like has a plurality of pads 2 and a chip carrier 4 has a plurality of terminals 3 to correspond to the pads 2 of this substrate 1 at a base part 41 and side parts 42. The carrier 4 is placed on the substrate 1, the terminals 3 are fixed on the pads 2 by a solder and an Si thermosetting resin 5 is made to flow in such a way as to cover the terminals 3 of the carrier 4. The resin 5 is filled in the gap between the substrate 1 and the carrier 4 and is left to stand until the peripheries of the terminals 3 of the carrier 4 are completely covered with the resin 5. After that, the resin 5 is heated and cured. By this method, even in case the peripheral temperature rises at the time of use and the solder, with which the terminals 3 are fixed on the pads 2, is fused, the fused solder does never flow because the terminals 3 are covered with the resin 5.

Abstract: PURPOSE:To reduce the effect of an error and to attain more accurate control by extending the counting period of time and implementing arithmetic operation with its mean counting value when an electric field input level is low and a period of time allowed for the control is longer. CONSTITUTION:An arithmetic operation 22 detects whether or not a receiver is at present in a hand-off state and when the receiver is not in hand-off state, a counted value DA by a counter 21 is fetched by 30 frequencies and its mean counted value is obtained. When the receiver is in hand-off state, whether or not an electric field input level detected by an RSSI 12 and an A/D converter 13 is -90dBm or below is detected. When the electric field input level is -90dBm or below, the counted value DA by the counter 21 is fetched twice and its average counted value is obtained. Where, the electric field input level is -90dBm or below and the counted period of time is 200msec. Thus, the error in the counted value DA in the case of deterioration in the S/N and fading or the like when the electric field input level is as low as -90dBm is averaged by two time averaging processing and the control as accurate as possible is ensured.
