Title: Earphone
Inventor: NONOMURA HIDEKAZU
IPC: H04R1/10
Filed: 1984-01-10
Abstract: PURPOSE:To improve clearness of conversation hearing when it is connected to a hearing aid by almost equalizing the diameter of the opening of the horn-like sound hole which is provided at the case of an earphone with the diameter of the sound route of the ear chip which is provided to the sound hole connectingly. CONSTITUTION:An earphone consists of an upper case 1, a main body of case 2, a diaphragm 4, an adaptor 5, an ear chip 6, a sound route 7 and a horn-like sound hole 8 in the conical horn type. The opening end of the sound hole 8 has the almost same diameter as that of the sound route 7. Thus, the step difference is not observed between the sound route 7 and the horn-state sound hole 8, acoustic resistance decreases because of the horn-like sound hole, and the resonance phenomenon between 2,000-4,500Hz is hardly observed. Therefore, peaks and troughs of frequency within the band of 2,000-4,500Hz which is most important on conversation hearing are hardly observed as shown in the characteristic diagram by the constitution of the execution example, and flatness of characteristics can be realized.

Title: Comparator circuit
Inventor: KOBA SHINICHIRO
IPC: H03K5/08
Filed: 1990-01-10
Abstract: PURPOSE:To reduce the power consumption by connecting an AND circuit which ANDs the output of a 1st field effect transistor(FET) circuit connected to a common input terminal with the output of a 2nd FET circuit inverted about the first output. CONSTITUTION:The gate electrodes of the 1st and 2nd FET circuits which differ in threshold value are connected to the common input terminal and the AND circuit which ANDs the output of the 2st FET circuit with the output of the 2nd FET circuit inverted about said output is connected. An inverter circuit consists of the FET circuits whose threshold voltages are specified and plural inverter circuits are connected in parallel to constitute the comparator circuit. Consequently, the number of elements is made much less than that for comparing operation by a conventional operational amplifier.
