摘要： PURPOSE:To improve the reliability at high repetitive operation by adopting the constitution such that a pulse voltage or a pulse current setting a gate starting point is fed to a main saturable reactor via a 2nd saturable reactor provided in a reset circuit. CONSTITUTION:A thyratron 3 is turned on for a gate period and the charge stored in advance in a main capacitor 5 is transferred to a capacitor 6. Most of a terminal voltage V6 of the capacitor 6 is applied to an output winding 11 of a main saturable reactor 10. The moment the energy in the main capacitor 5 is almost transferred to the capacitor 6, the magnetic flux density of the main saturable reactor 10 is saturated and the inductance of the output winding 11 of the main saturable reactor 10 is rapidly reduced and the energy in the capacitor 6 is transferred to the peaking capacitor 8. Thus, highly efficient operation of a high voltage pulse generating circuit and repetitive operation capable of output control is facilitated and the production of output jitter is suppressed.

摘要： PURPOSE:To suppress a decrease in an energy transfer efficiency and an increase in loss of a switch element by providing a variable inductance for controlling the width of a voltage pulse to be applied to a saturable reactor at an input side. CONSTITUTION:A variable inductance 20 is provided at the input side of a main capacitor 5. The inductance 20 is formed, for example, in a solenoid coil shape, and the value of the inductance can be reduced by elongating the axial length of the coil. The axial length of the coil is varied in response to an input voltage, and a saturable reactor 8 is saturated for a period of time when the energy input to a peaking capacitor 10 becomes maximum. Thus, even if the operating magnetic flux density amount, etc., of the reactor 8 is varied, a condition such as an optimization of the energy transfer efficiency can be maintained.

摘要： PURPOSE:To obtain a magnetic head of high recording quality and a low inductance by providing a magnetic metal film of a required magnetic characteristic in the back gap part of a magnetic head in which I-shaped and C-shaped cores are so combined as to face each other. CONSTITUTION:An I-shaped core 2 and a C-shaped core 3 which respectively have metal magnetic thin films 4, 5 in their facing surfaces are so combined as to face each other to form a magnetic head which has a magnetic gap 6 and a back gap on the opposite side of the gap 6. A magnetic metal film 1 having a magnetic characteristic which is equal to or above those of the cores 2, 3 is provided in the back gap part, so that the cores 2, 3 conduct mgnetically. Thereby, the magnetic flux of the back gap is not diffused but converged to make a magnetic head of a low inductance, the magnetic reluctance of which is small and the magnetic recording quality of which is increased.

摘要： PURPOSE:To form the high-performance magnetic head dealing with the trend toward a higher recording density by arranging magnetic metallic thin films of the same kind as magnetic metallic thin film or the kind different therefrom on the flank of magnetic core subjected to stepping for regulating a track width by clamping the recording magnetic fields generated at the time of recording and the flanks on the side opposite to these flanks. CONSTITUTION:The metal-in gap magnetic head of a both film type is formed by butting the I-shaped core 10 and the C-shaped core 11 against each other and arranging the magnetic metallic thin films 7, 8 on the butted surfaces of I and C both cores. These films are formed out of a material having the saturation density higher than the saturation density of the magnetic cores 10, 11. The magnetic metallic thin films are arranged on at least a part of the flank of the magnetic cores subjected to stepping for regulating the track width by clamping the recording magnetic fields generated at the time of recording and the flanks on the side opposite to these flanks. The saturation magnetic flux density of the thin films 7 is higher than the saturation magnetic flux density of the thin films 1, 2 to introduce the magnetic fluxes efficiently to the gap 9 like a route 14.

摘要： PURPOSE:To continuously operate the title high voltage pulse generator for a long time by a method wherein the high voltage pulse generating magnetic parts provided with a case containing magnetic cores and a refrigerant as well as split parallel windings formed of flat plate type conductor are used. CONSTITUTION:Magnetic cores 8 wound up with an amorphous magnetic band for insulation are contained in a cylindrical conductor 2. Ring type insulators 7 fill the roles of fixing the wound up magnetic cores 6 and regulating the flow of a coolant for cutting off said flow while the other ring type insulators 8 fill the roles of avoiding the mutual contact between the wound up magnetic cores 6 and evenly cooling down the ends of the magnetic cores 6. The insulator 9 fills the roles of insulating the input.output terminals 1, 3 and sealing up a refrigerant while the other insulators 10, 11 fill the roles of making the alignment of the whole body of said magnetic cores 6 and retaining the whole body of the components. The split parallel windings 12 made of flat plate type conductor are insulation-coated in high withstand voltage to be wound up in parallel with one another in both right and left directions from the initial winding position to the opposite pole of the magnetic cores 6. In such a constitution, the refrigerant runs from an oil inlet 4 to an oil outlet 5 in the flow channel order as shown by arrows.
