Patent JP-S63232605-A (JP)
Title: Automatic frequency control circuit
Inventor: YASUKI TOSHIHARU
IPC: H03C3/00
Filed: 1987-03-20
Abstract: PURPOSE:To attain accurate frequency modulation by providing a demodulation means demodulating an output signal and an adder means adding a signal outputted from the demodulation means and an input signal in opposite phase to each other to a detection means detecting the center frequency of a modulated output signal and eliminating the frequency change component of the output signal so as to detect the center frequency. CONSTITUTION:After the output signal is demodulated by an FM demodulation circuit 2, the signal is added to the input signal in opposite phase by a comparator amplifier circuit 3. Thus, the output of the comparison amplifier circuit 3 is detected for the frequency change component of the output signal depending on the input signal and only the frequency change component generated in the inside of the frequency modulation circuit 1 due to temperature change or change in the lapse of time or the like is detected. Thus, the comparator amplifier 4 compares the output of the amplifier circuit 3 with a reference voltage to control the output center frequency of the frequency modulation circuit 1. Thus, the AFC circuit independent of the input signal is formed. Thus, the frequency is modulated accurately even to the input signal having a signal component slower than the response speed of the AFC circuit or the DC component.

IPC: G01P13/04
Filed: 1985-03-29
Abstract: PURPOSE:To prevent miscounting, by arranging a gate circuit so that a logical computation is performed between output signals of first and second differentiation circuits and A-phase and B-phase pulses to generate pulses for respective countings at the rise and fall of the A phase and B phase pulses. CONSTITUTION:A logical computation is performed between output signals of first and second differentiation circuits 20 and 21 and A phase and B phase pulses. At the times t1, t3, t5 and t7, output signals alone of AND gates 34, 37, 35 and 36 will be '1' signals by logical computations with respective gates. On the other hand, at the times t2, t4, t6 and t8, all of output signals of the AND gates 30-37 will be '0' signals. In other words, at the times t1, t3, t5 and t7, signals Sa4, Sb3, Sa3 and Sb4 are outputted through the gates 34, 37, 35 and 36 and an OR gate 41 and in this case, the pulse signal outputted from the gate 41 turns to a forward pulse CW. Then, following the time t8, waveforms at the times t1-t8 appear repeatedly and the pulses CW are outputted four times at a cycle of the A phase pulse (or the B phase pulse).

Abstract: PURPOSE:To quickly respond to system-down of a main data-way, by providing an auxiliary line connecting between a master station and each slave station and switching the channel to subdata-way at the down time of the main data-way.

Title: Controlling system for copying device
Inventor: KIKUCHI HIDEO
IPC: G03G21/00
Filed: 1981-05-01
Abstract: PURPOSE:To eliminate operating errors and to make operation easier by comparing a fresh operation mode with an old operation mode when it is inputted and deciding whether copying inhibition is okay or not in accordance with the results thereof. CONSTITUTION:When a fresh operation mode is inputted to a keyboard control circuit 69, this is set in a register 70, and is compared with the old operation mode set in a register 74 in a comparing and operating circuit 73. According to the results of the comparison, a decision circuit 74 checks whether the fresh operation mode can be executed or not. If both are not equal and the fresh operation mode cannot be executed, the inhibition of the operation is displayed. If it is possible to execute the fresh operation mode, the inhibition of copying is canceled, and the content of the register 70 is set in the register 74. Therefore if the operator changes the gathering mode inadvertently to a sorting mode after the operation end of the former mode, the copying is inhibited, but if he returns it to the gathering mode, the copying is feasible, whereby the operation errors are eliminated and the operation is made easier.

Abstract: PROBLEM TO BE SOLVED: To obtain a satisfactory balance of the oscillation part of a damper and to improve the linearity very much by giving a vertically and horizontally symmetrical shape to the hollow doughnut damper which supports a voice coil and has air-permeability. SOLUTION: A first damper 1A is formed with air-permeable cloth as the base cloth so as to have a hollow doughnut section, and an inner peripheral edge part 1Aa of the doughnut part is coupled to a voice coil 4, and an outer peripheral edge part 1Ab of the doughnut part is coupled. To a frame 5. Thus, the damper is deformed while following up the vertical movement of the voice coil 4 well. Since the shape of the damper 1A is formed like a doughnut and is made vertically symmetrical, the difference in stiffness between upward displacement and downward displacement is considerably reduced. Thus, the linearity of the damper 1A is considerably improved, and the nonlinear distortion for a large amplitude is reduced.

Abstract: PROBLEM TO BE SOLVED: To provide a constitution capable of expand lighting a light transmission band at the time of inputting a light beam outputted in the different direction by means of a wavelength angular dispersing element to an output optical fiber. SOLUTION: In the constitution inputting an optical signal inputted from an input fiber to a wavelength angular dispersing element such as a diffraction grating, converging a light beam dispersed in the different directions for every wavelength by a condenser lens and inputting it to an output fiber, the distribution of electric field of the output fiber viewed from the side of the condenser lens is composed so as to become a twin-peak shape (a).

These are realized by bisecting the tip of the output fiber or using a phase mask.  By this constitution, the wavelength dependency of transmissivity of nearly a rectangular shape as shown in (b) is obtained and the light beam is transmitted through the output fiber with high transmissivity even when the wavelength is slightly deviated, the spectrum is widened by modulation and the position of the output fiber is slightly deviated.

Title: Magnetic head
Inventor: MARUTA YUZO
IPC: G11B5/187
Filed: 1988-03-23
Abstract: PURPOSE:To prevent the information reliability of a magnetic head from being lowered by fitting thin films of a superconductive substance to a part of the magnetic medium facing surface and a part of vacant space of its core. CONSTITUTION:Thin films 7 composed of a superconductive material whose transition from a superconductive state to a normal conductive state can be controlled are fitted to a part of the magnetic medium facing surface of vacant space 3 of a core 1 and a part of the vacant space. When the thin films 7 are set to normal conductive states by making electric currents exceeding critical currents of make flow to the thin films 7 at the time of recording, the Meissner effect of the thin films 7 disappears and magnetic flux is allowed to pass through the films 7. When the thin films 7 are set to superconductive states by making electric currents which do not reach the critical currents to flow to the films 7 at the time of reproduction, the magnetic flux produced from a magnetic medium 5 cannot enter the core 1 since the films 7 respectively have Meissner effects. The effective vacant space width in this case becomes the value (a-2b) which is obtained by subtracting the width (2Xb) of the thin films 7 from the vacant space width (a) at the time of recording. Namely, recording is performed with the wider vacant space width and reproduction is performed with the effectively narrower vacant space width. Therefore, lowering of the reliability of reproduced information can be prevented.
