Title: Synchronizing signal transmitting method
Inventor: TSUBAKI MASAMITSU
IPC: H03L7/14
Filed: 1995-04-04
Abstract: PURPOSE: To transmit a signal at a high speed and increase the transmission distance by allocating a signal from a frequency division part when a received signal has no clock component, and varying the frequency of a frequency-divided signal from an oscillator and putting the signal in phase when a clock component is extracted. CONSTITUTION: The received signal is received by a receiver 3 and threshold processed. The signal from the oscillator 4, on the other hand, has its frequency divided by a frequency division part 1 and further divided by a frequency division part 2 and is outputted as a received clock to a reproduction part 7. If this received signal is not received or if the received signal is transmitted, but does not have transition between 0 and 1, this received clock is sent out as a received digital signal. When the received signal is transmitted and has transition between 0 and 1, an extraction part 5 detects the transition and outputs a clock and a phase shift part 6 shifts its phase by 90 deg.. A comparison part 8 compares the phases of the outputs of the phase shift part 6 and frequency division part 2 with each other.  A phase difference larger than a specific value is outputted to an indication part 70 when present and a rejection alarm signal is outputted. A comparator 8, on the other hand, outputs the value of the phase difference to a control part 9 as is and sends a control signal out to the frequency division part 1 to vary the frequency division ratio and adjust the phase, thereby performing synchronized transmission.

Abstract: PROBLEM TO BE SOLVED: To provide wide band characteristics of low power consumption by making a load of a gallium arsenide magnetic field effect transistor which constitutes a source follower circuit a load circuit which has a gallium arsenide magnetic field effect transistor for voltage amplifying an input luminance signal. SOLUTION: A gate of GaAsFET2 is grounded by a capacitor C2 by a high frequency and, since it is biased, a source of the GaAsFET2, that is, a voltage of a drain of a GaAs FET1 becomes almost constant. Thus, a luminance signal Vin is inputted to the GaAsFET1, but since the source of the GaAsFET2 is voltage fixed, the GaAsFET1 performs current amplification only. This current amplified source current (is) flows to a load resistance RL, becomes an output voltage V1 of this input circuit and silicon bipolar transistors Tr1 and Tr2 of an output step power amplifying circuit are driven by this output voltage V1.

Title: Soft magnetic thin film and magnetic head using such thin film
Inventor: HORI TORU
IPC: G11B5/31
Filed: 1989-03-30
Abstract: PURPOSE:To obtain a soft magnetic thin film having high saturation magnetic flux density and having both high durability and high permeability by laminating layers of iron carbide and iron alternately. CONSTITUTION:Layers of iron 12 and layers of iron carbide 11 having a concentration of C in a range corresponding to positive magnetostrictive constants are laminated alternately. According to such an arrangement, even if carbon is incorporated in the iron carbide layers 11 in an amount enough to present sufficient durability at the sacrifice of saturation magnetic flux thereof, the presence of the pure iron layers 12 ensures sufficient saturation magnetic flux and instability of the pure iron layers 12 can be compensated by the adjacent iron carbide layers 11. Further, the negative magnetostriction of the pure iron layers 12 and the positive magnetostriction of the iron carbide layers 11 are cancelled each other, whereby the soft magnetic thin film thus obtained is allowed to have sufficiently high permeability also. Accordingly to the invention, consequently, the soft magnetic thin film having high saturation magnetic flux density is allowed to have both high durability and high permeability.
