Title: Antenna device and communication apparatus using the same
Inventor: KAWABATA KAZUYA
IPC: H01Q5/10
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To improve the antenna gain of an antenna whose resonance frequency is low and to make the variation of the antenna gains in the plural antenna small by mounting the plural surface mount antennas on the substrate and arranging the antenna whose resonance frequency is lower in a position nearer to the end part of the substrate. SOLUTION: An antenna device 1 is constituted of the two surface mount antennas 3 and 4 mounted on the substrate 2. The resonance frequency of the surface mount antenna 3 is lower than the resonance frequency of the surface mount antenna 4. The antenna 3 is arranged near the corner part of the substrate 2 and the antenna 4 is arranged adjacently to the antenna 3 in a direction detached from the corner part. The route of the electric line of force between the opening end of the radiation electrode in the antenna 3 and a ground electrode 6 becomes partially long and the concentration of electric fields is relieved. Since the leakage of the electric field increases by the amount, a radiation resistance drops and the antenna gain is improved.

Title: Dynamic type electroacoustic transducer
Inventor: OOMORI TATSUYA
IPC: H04R9/06
Filed: 1983-05-10
Abstract: PURPOSE:To faithfully regenerate an analog waveform, by connecting series resistances with (N-1) pieces of dynamic transducing elements and setting the overall electroacoustic transducing efficiency containing a voltage drop due to the resistances to a magnitude which is proportional to the weight of corresponding bits. CONSTITUTION:Series variable resistances R1, R2,-R(N-1) are respectively connected to (N-1) pieces of voice coils 41, 42,-4(N-1) and the overall efficiency containing the efficiency down of each dynamic transducing element due to the voltage drop of the said series variable resistances is set to a magnitude which is proportional to the weight of each bit. Since the signal pulse has a constant amplitude and the dynamic transducing element corresponding to each bit of an electroacoustic transducer has an electroacoustic transducing efficiency proportional to the weight of each bit, the electroacoustic transducer radiates sound pressures proportional to the weight of each bit, when an N-bit digital signal is impressed upon the transducer. The sound pressures are combined in a space and, as a result, an analog acoustic signal is radiated.

Filed: 1990-03-29
Abstract: PURPOSE:To permit an easy detection of a relative position between a head board and a printed board upon press fit between their connecting terminals by providing a detecting terminal for positional shift in a row of connecting terminals of the printed board and the head board. CONSTITUTION:A head board 1 is provided with a detecting terminal 7 for positional shift at its press-fit part and a printed board 2 is also provided with detecting terminals 8-1 and 8-2 for positional shift at its press-fit part. The detecting terminals 8-1 and 8-2 are extended to the measuring terminals 6-1 and 6-2 of the printed board 2 to check for conducting and non-conducting states between the measuring terminals 6-1 and 6-2, whereby the positional shift can be detected. In a case without the positional shift, the detecting termi nal 7 of the head board 1 is lapped over both the detecting terminals 8-1 and 8-2 of the printed board 2 by a width W. In a case with the positional shift larger than the width W, the detecting terminal 8-1 is out of contact with the detecting terminal 7. Therefore, the conducting and non-conducting states be tween the measuring terminals 6-1 and 6-2 are detected and, if the positional shift becomes larger than the width W, a non-conducting state takes place to indicate at once that the positional shift exceeds the allowable tolerance.
