Title: Double-cassette tape recorder
Inventor: HATANAKA TOSHIHIKO
IPC: G11B5/027
Filed: 1987-05-18
Abstract: PURPOSE:To improve the frequency characteristic at the time of normal speed reproduction without making the frequency characteristic at the time of high- speed reproduction worse, by inserting a capacitor between the input of a reproducing amplifier and earth when a magnetic tape is reproduced by connecting a 1st reproducing head and a 2nd recording and reproducing head in series. CONSTITUTION:A reproducing peaking capacitor 13 is connected between a reproducing head 1 and earth. Firstly, the reproducing peaking frequency is determined by the resultant impedance of the capacitor 13, the reproducing head 1, and a recording and reproducing head 2 at the time of reproduction, since the heads 1 and 2 are connected in series. At the time of recording, moreover, the reproducing peaking frequency is determined by the head 1 and capacitor 13. Therefore, when the inductance of the head 1 is equal to that of the head 2, the reproducing peaking frequency at the time of reproduction becomes lower to the 1/2<1/2> of that of the recording time and the reproducing frequency characteristic at the time of normal-speed reproduction can be improved without making the frequency characteristic at the time of high-speed reproduction worse.

IPC: H01L27/12
Filed: 1992-05-13
Abstract: PURPOSE:To reduce the power consumption of the integrated circuit of a driving circuit part and to eliminate a leak current due to the parasitic channel of the switching transistor of a pixel part by making a specific semiconductor single-crystal silicon layer thinner than the silicon layer in an area where a driving circuit element group is formed. CONSTITUTION:At the driving circuit part, the thickness t3 of the single crystal silicon in the area of an N type MOS transistor is made thicker than the thickness t2 of the single crystal silicon in the area of a P type MOS transistor. Consequently, neither of the bottoms of the source electrode 1007 and drain electrode 1008 of the N type MOS transistor contacts a silicon oxide film 11 as a substrate and the bottom of a field oxide film 1005 in the area where the N type MOB transistor is formed, i.e., in a P well 1006 does not contacts the silicon oxide film 11 as the substrate. Consequently, the parasitic channel of the N type MOS transistor is not generated and the leak current is suppressed small.
