Title: Common-emitter type amplifier circuit, magnetic head device and magnetic record reproducing device
Inventor: SHIIMOTO TSUNENORI
IPC: G11B5/027
Filed: 1994-04-15
Abstract: PURPOSE:To provide a small-sized reproducing device which is large in the gain of reproduced signals and high in the switching speed between recording and reproduction by installing a switch between the emitter of a transistor to which is inputted a reproduced signal from a magnetic head and the earth. CONSTITUTION:A recording amplifier(amp) 3 does not operate in the reproduction mode but outputs a signal S3 to drive a head H1 in the reproduction mode. In the reproduction mode, the emitter of Q1 is grounded and the number of circuit elements decreases compared with the one in the past, resulting in a larger dynamic range of the reproduced signal S2 that much. In addition, non- existence of large bypass capacity quickens recording/reproduction switching, and a reproduction amp 8 can be formed on a semiconductor chip and miniaturized. At the time of recording, SW4 brings Q1 to the off state in which the input of signal S3 causes no action, bringing about no deterioration of high-frequency characteristics due to parasitic capacity because there exist no surplus SWs. At the time of reproduction, the throwing of the SW4 has no bad effects of parasitic capacity CP4 on the action of head section 7.

Filed: 1987-04-24
Abstract: PURPOSE:To make a polarization process needless by keeping a substrate's potential positive to a wall of an evaporation room to perform film formation when a ferroelectric thin film with prescribed compositions is manufactured by a sputtering evaporation method. CONSTITUTION:A ferroelectric thin film is made of a material which is expressed in a chemical formula PbxLayZrwTizO3 and has either of the following compositions:a) o.7<=x<=1, 0.9<=x+y<=1, 0.95<=z<=1, w=0, b) x=1, y=0, 0.45<=z<1, Z+w=1, c) 0.83<=x<=1, x+y=1, 0.5<=z<1, 0.96<=z+w<=1. When this ferroelectric thin film is manufactured on a conductive substrate by a sputtering evaporation method, a substrate's potential to a wall of an evaporation room is kept 30V or more to perform film formation. Even if the substrate is conductive, a ferroelectric thin film, in which Ps has already been naturally polarized, is obtained accordingly and so a polarization process can be made needless.

Title: Superconductive thin film circuit
Inventor: KAMIKAWA TAKETOMI
IPC: H01P1/203
Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To set the sensitivity of a mixer to be high and to miniaturize a circuit by arranging a superconducting antenna and a superconducting filter on a substrate at the distance of not less than 1/2 of the wavelength of an electromagnetic wave in the substrate transmitted and received by the superconductive antenna. SOLUTION: The RF signal of 12 GHz is received in the antenna 13 and it is frequency-mixed with the LO wave of 11 GHz, which is inputted through an LO filter 15. Then, the IF signal of 1 GHz is taken out. An RF filter 14 is inserted between the antenna 13 and the mixer 16. The filter removes noise entering from the antenna 13 and prevents the LO wave from reaching the antenna 13 and being prevented from it. When the distance between the antenna 13 and the RF filter 14 is called (d) and a reception wavelength is called λ, and the reflection coefficient becomes suddenly large when d/λ becomes smaller than 1/2 and the mutual interference of the antenna and the RF filter becomes strong. Thus, d/λ is set to be not less than 1/2 to avoid interference with the RF filter and to sufficiently extract the antenna ability.
