Abstract: PURPOSE:To raise the machining speed by a method wherein a resonance circuit is provided in series in a machining aperture and an oscillator is oscillated by the resonance power of the resonance circuit, thereby the oscillation being performed in conformity with the best condition at all times. CONSTITUTION:When an electric discharge is performed into a machining aperture by a pulse which a machining power source 5 supplies, the series resonance circuit of an oscillator 6 and an inductance 7 is oscillated by the discharge of the machining aperture, and a high-frequency oscillation is generated by the flow of the resonance current to the oscillator 6 and is made to act on an electrode 1 through a horn 4. Since the resonance circuit makes discharge resonate with the high frequency, it can make the former resonate with any optional high frequency in accordance with a circuit constant and can make the electrode perform the high-frequency oscillation.

Abstract: PURPOSE:To provide fewer man-hours for production, higher yield and lower cost than in the case of formation of magnetic metallic films by forming a 1at core of a material having higher saturation magnetic flux density than the saturation magnetic flux density of a 2nd core. CONSTITUTION:The core 11 (1st core) is formed on a leading side and the core 12 (2nd core) on a trailing side. A magnetic gap 13 is formed in a part thereof and the cores are joined by glass, etc. Both the cores 11 and 12 are formed of ferrite. The core 11 is formed to have the saturation magnetic flux density higher than the saturation magnetic flux density of the core 12. The magnetic flux density of the core 11 on the leading side is, therefore, higher than the magnetic flux density of the core 12 on the trailing side. In addition, the rise is steep on the former side and is gentle on the latter side and the need for widening the gap width is eliminated. The production process is simplified in this way and the yield is improved.

Title: Booster power amplifier
Inventor: ASARI NORIYUKI
IPC: H03G3/30
Filed: 1990-03-22
Abstract: PURPOSE:To amplify the electric power with the stable gain characteristic by detecting both input and output electric powers and deciding an amplification degree based on the rate of each detected voltage. CONSTITUTION:A voltage comparator 4 controls the attenuation degree of a voltage control attenuator (PIN diode attenuator) 2 so as to secure the coincidence between the detection voltage level of an input detection circuit 1 which is amplified up to a prescribed magnification and the detection voltage level of an output detection circuit 6. The log linear relation is secured between the electric power to be detected and the detection voltage for each of both circuits 1 and 6. Therefore the power amplification gain is proportional to the prescribed magnification of an input detection voltage amplifier 3. Thus the stable gain characteristic is secured without remodeling a transmission device.
