Title: Sine wave oscillation circuit
Inventor: TAMASO HARUO
IPC: C08F8/44
Filed: 1985-04-17
Abstract: PURPOSE:To obtain a stable oscillating output extending over a side frequency range by forming an oscillation circuit by utilizing an amplifying action between one input and an output of a multiplier, and also controlling the gain in the amplifying action of this multiplier by the other input of the multiplier. CONSTITUTION:In case when an oscillation circuit is not in an oscillating state, an initial voltage applied to an input terminal Y of a multiplier 1 is a voltage of a DC power source 11 and an oscillating operation is started. When an oscillation amplitude of an output terminal Z comes to turn on a transistor Tr 7, the voltage of the terminal Y of the multiplier 1 drops due to a voltage drop of a load resistance 10 by a collector current of the Tr 7 and an amplification degree of the multiplier 1 is made smaller, and an action is generated in the direction for making an amplitude of an oscillating output smaller. As a result, the loop gain of the oscillation circuit is controlled to '1' so that the amplitude of the oscillating output is set to a prescribed value, and a stable oscillating state can be obtained. Also, by controlling the loop gain, a stable state is obtained only in an oscillation related to a frequency of the maximum point of a transfer characteristic against its loop frequency, and an oscillation of a sine wave is generated.

IPC: G11B5/127
Filed: 1980-06-19
Abstract: PURPOSE:To increase track density easily by reducing intertrack crosstalk by specifying an intersectional angle between magnetized inversion surfaces of adjacent recording tracks. CONSTITUTION:When an intersectional angle alpha between magnetization inversion surfaces 22 of  adjacent recording tracks 32-34 which is the least common multiple of magnetization inversion  intervals of recording on the recording tracks 32-34 is beta and track width is (h), the recording is  so performed that the equation holds. The boundaries of the recording tracks, on the other hand,  are shown by 31.

When the  energizing direction of the auxiliary magnetic pole 15 is changed according to the signal current  flowed through the coil 16, the vertically magnetized film is magnetized for recording as shown by  the arrow of a sign 21. When the film surface of the main magnetic pole 14 is placed at right  angles to the moving direction 13 of a recording medium, the magnetization inversion surfaces 22,  which are the boundaries of magnetization inverted alternately, cross the moving directions 13 of  the vertically magnetized film 11 and the recording medium nearly at right angles and become  parallel to the main magnetic pole 14.

Filed: 1983-05-13
Abstract: PURPOSE:To improve a using procedure sequentially by storing the corrected contents of results obtained by converting ''kana'' (Japanese syllabary) into ''kanji'' (Chinese character) by an operator. CONSTITUTION:For instance, an operator inputs ''haikei   kisha masumasu goseiei no koto to'' (starting words of a letter, provided that   is a space) and then depresses a conversion key. Consequently, display as shown in the figure A is outputted and a cursor K indicating an input position indicates the 17th character. If the display of ''HAIKEI'' (dear sir) is not satisfied, the cursor K is backed to the 3rd column and then a display correction key is depressed. Consequently, the display of ''HAIKEI'' (dear sir) is converted into ''kana'' by a conversion dictionary storage part (figure C). The status (''kanji'' display or ''kana'' display) of the display correction key set up by said operation can be used as a display correction mode specifying key for specifying whether the status of the display correction key is used as temporary memory in the documentation or parmanent memory to be used for another documentation to be executed successively.
