Title: Flying object searching system
Inventor: SAITO TOSHIO
IPC: H04B1/38
Filed: 1993-12-29
Abstract: PURPOSE:To search a position of a flying object by transmitting a first signal wave having a predetermined frequency from a master unit to the object, and transmitting a predetermined second signal wave from the object to the unit in response to the first wave transmitted from the unit. CONSTITUTION:A transmitter 20 turns on a transmission control switch 17 to supply power to a transmitting circuit 18, which generates a signal wave, and the wave is transmitted to a flying object via a transmitting antenna 19. A receiving antenna 21 of a receiver 25 receives the wave transmitted from the object. The received wave is shut off at the wave having a frequency generated from the circuit 18 for interfering a receiving circuit 23 by a filter 22. Then, it is amplified by the circuit 23, its DC voltage is rectified by a signal detector 24, and output. A position of the object is recognized by rotating the antenna 21 so that a direction indicating a highest value of the DC voltage detected value of the detector 24 is a direction in which the object exists. Then, a distance is calculated from the DC voltage value, and the position of the object is searched.

Abstract: PROBLEM TO BE SOLVED: To improve the reliability of a semiconductor device by preventing it from being air caught up in due to variations in resin injection rate and by increasing the resin injection rate, in an underfill process of a chip-size package having a structure in which a semiconductor device is mounted in a facedown condition. SOLUTION: A protruded metal electrode 8 formed on an electrode 7 of a semiconductor 6 and an electrode 10 of an interposer substrate 5 are connected by a conductive connecting materials 9. In this case, the interposer substrate 5 mounted on the semiconductor 6 is supported on a heating stage 11 for sealing the resin, and a resin 12 is injected between the interposer substrate 5 and the semiconductor device 6. In injecting the resin, the heating stage 11 for sealing the resin is constituted, so that the central part of the interposer substrate 5 is set at a higher temperature that those of both sides of the interposer substrate 5. As a result, resin adhesion degree is lowered in the central part of the interposer substrate 5 due to high temperature, and the resin injection rate becomes high. Therefore, homogeneous resin injection can be ensured.  After the resin injection, heating and hardening of the resin are conducted in an oven.
