Title: Household signal transmitting device
Inventor: KAKIZAWA TOSHIO
IPC: H04B3/54
Filed: 1980-07-22
Abstract: PURPOSE:To eliminate the malfunction of a household signal transmitting device even in case the noise gets into a lamp wire, by producing a digital signal synchronoulsy with an AC power source when the digital signal is serially transmitted via the lamp wire. CONSTITUTION:The commercial AC signal applied between AC power supply lines 2 and 3 is supplied to a micrcomputer 11 after the rectification through a full wave rectifying circuit 4 and the shaping through a waveform shaping circuit 14 and turned into a synchronous interruption signal. Receiving an external operation, an input signal 19 of a transmitting device 1 applies a parallel digital signal to the computer 11. Thus the computer 11 converts the parallel signal into the serial one every time the interruption signal is supplied to an interruption terminal INT. This serial signal is modulated at an AND21 by the carrier wave sent from an oscillator 20 to be sent to the area between the AC power sources 2 and 3 via a transformer 23 and a capacitor 24 after the amplification carried out through a transistor 22.

Filed: 1987-04-23
Abstract: PURPOSE:To remarkably reduce the current consumption of the titled circuit by providing a differential switch between the emitter of 1st and 2nd emitter transistors(TRs) and a current source. CONSTITUTION:A complementary binary logic, for example, a high voltage level to a 1st input terminal 2 and a low voltage level to a 2nd input terminal 3, is fed respectively to the two input terminals 2, 3 in an emitter follower circuit. In this case, each input activates a differential switch composed of 3rd and 4th TRs 8, 9 through level shift circuits 11, 12. In this case, the 4th TR 9 having a base with a high voltage applied complementarily thereto is turned on and a current nearly equal to a current of a current source 10 coupled with the emitter flows to the 4th TR 9. Then the emitter of a 2nd TR 7 whose base is at a low level is decreased to the low voltage level and a low voltage level is outputted to a 2nd output terminal 3.

Title: Timing extracting circuit
Inventor: TAKADA AKIHIKO
IPC: H04L7/027
Filed: 1984-05-21
Abstract: PURPOSE:To quicken a rise time of a timing clock by enlarging the amplitude of an input of a band pass filter by an integration circuit and a variable gain amplifier. CONSTITUTION:A random digital signal is inputted to a rectifying circuit 10. In the rectifying circuit 10, this random signal is rectified, and inputted to an integration circuit 50 and a variable gain amplifier 60. When a rectifying wave is inputted to a transistor of the integration circuit 50, a collector current flows and charge is accumulated in a capacitor. A voltage of a frequency appearing in the upper end of a resistance by a time constant of a CR circuit is applied as an input voltage of a variable impedance element, and an output of the variable gain amplifier 60 rises most suddenly in the beginning, and thereafter, settles down gradually to a prescribed value. Therefore, the input amplitude of a band pass filter 20 becomes large, therefore, a rise time of a timing clock signal can be quickened.

IPC: H01F41/20
Filed: 1993-04-27
Abstract: PURPOSE:To prevent the deterioration in magnetic characteristics by the excess oxygen content in the initial part of formation of a magnetic layer and to improve magnetic recording and reproducing characteristics by introducing oxygen into a vacuum vessel and maintaining a nearly specified oxygen concn. distribution in the layer thickness direction of the magnetic layer formed by continuous vapor deposition. CONSTITUTION:An oxygen introducing pipe 4 is placed between a shielding plate 3b for regulating the incident angle of evaporated atoms on a high-molecular substrate 5 and a cylindrical can 8 on the final period side of the formation of the magnetic layer so that the oxygen quantity on the initial period side of formation of the magnetic layer is decreased as far as possible. Further, rare earth atoms or yttrium atoms are evaporated from an evaporating source 2 for oxidation near the part where the evaporated atoms in the initial period of formation of the magnetic layer are made incident on the high-polymer substrate 5. The evaporated atoms of the rare earths or yettrium are more easily oxidized than the metal atoms of Co, etc., constituting the magnetic layer and are, therefore, bonded preferentially to the oxygen infiltrating to the initial period side of the formation of the magnetic layer to prevent the excess incorporation of the oxygen into the magnetic layer.
