摘要： PROBLEM TO BE SOLVED: To shorten the development time and the manufacturing time of a multichip module having excellent high frequency characteristics, by forming the multichip module of laminated structure by the three layers of a top-face sealed substrate, a passive-element substrate and an active-element substrate. SOLUTION: A multichip module 1 is formed in the laminated structure of a top-face sealed substrate 2, a passive-element substrate 3 and an active- element substrate 4. The top-face sealed substrate 2 is formed in structure having a first insulating layer 6 and first adhesive layer 7 on the rear of a metal plate 5, and a hollowed-out region 8 is formed to parts of the first insulating layer 6 and the first adhesive layer 7. An inert gas is sealed into the hollowed-out region 8, and a sealing film 30 is formed onto a side face. Since each substrate-forming temperature condition is determined discretely by forming the top-face sealed substrate 2, the passive-element substrate 3 and the active- element substrate 4 by separate process respectively in the multichip module 1, the constraint of each substrate-forming temperature condition is reduced, and the substrates are manufactured easily.

摘要： PROBLEM TO BE SOLVED: To provide a technology to mount an antenna inside a case of the portable radio terminal at a low manufacture cost with less electromagnetic interference between a high frequency circuit section and a low frequency circuit section and without reducing a directivity gain of the antenna and causing improper contact of a connector. SOLUTION: The portable radio terminal has a high frequency circuit board 10, a shield case shielding part of the high frequency circuit board 10 electromagnetically and a plate antenna 30 mounted on the high frequency circuit board 10. In this case, a window is formed to the shield case so that part of the face of the high frequency circuit board 10 is exposed, the plate antenna 30 is connected electrically and mechanically onto the high frequency circuit board 10 in the window, part of the shield case is extended and the shield case and a low frequency circuit board 40 are pinched by the case of the terminal to fix them. Thus, the antenna is built in the portable radio terminal without causing increased manufacturing cost or improper contact of the connector, with less electromagnetic interference between a high frequency circuit section and a low frequency circuit section and without directivity gain drop, and the portable radio terminal is realized by improving the performance of miniaturization and container so as to improve the carrying performance.

摘要： PURPOSE:To attain easy and excellent transmission without requiring strict impedance matching by providing a capacitive or inductive coupling means for external connection to both ends of a transmission line and specifying the electric length of the transmission line. CONSTITUTION:A low impedance load 2 by capacitive coupling and a bonding wire 3 by inductive coupling are connected to a microstrip line 1 being a transmission line in a chip 4. The electric length L of the transmission line 1 is selected to be a multiple of (2n-1)/4 (n is an integer) such as 1/4 with respect to a wavelength lambdaof a transmission waveform when the capacitive coupling is adopted for one end of the transmission line and the inductive coupling is adopted for the other end of the transmission line in this way and the electric length L of the transmission line 1 is selected to be a multiple of n/2 when the capacitive coupling is adopted for both ends of the transmission line or the inductive coupling is adopted for both ends of the transmission line. A standing wave in which a voltage node is formed at the load 2 and a current node is produced to the bonding wire 3 is produced on the transmission line 1. Thus, no voltage fluctuation takes place in the load 2 and no current fluctuation is caused in the bonding wire 3 whose impedance is high and the transmission characteristic is not affected by the standing wave.

摘要： PURPOSE:To reduce noise during the running period of vehicle over all propagation area as well as provide a noise-damping function for a guide wheel receiver by a method in which the upper guide wheel receiver of the side wall of a U-shaped guide track is connected organically with a concrete wall to support it. CONSTITUTION:A guide wheel receiver 19 is supported through a space between the receiver 19 and a concrete wall and noise-passing holes 26a and 26b and a perforated plate 24 are provided for a guide wheel face plate 22. Horizontal control holes 27a and 27b and vertical control holes 23a and 23b are formed in the concrete wall to reduce radiant noise by phase bias of passing noise by combination of them. By using a noisereducing box 20 in which a sound absorber 21 is attached to the inner surface of the perforated plate 24 of the guide wheel face plate 22, resonance noise absorption is taken place to reduce noise level value to be transmitted to the ground's surface. By utilizing the control holes 23a, 23b, 27a, and 27b formed in the receiver 19 and the track beam 14 constituting the track beam 14, noise during the running period of vehicle 11 can be damped over all propagation area.
