Title: Igniting apparatus for high frequency discharge in magnetic field
Inventor: ABE TAKAO
IPC: H05H1/30
Filed: 1994-11-08
Abstract: PURPOSE: To avoid a hindrance of a chemical reaction due to impurities or avoid contamination of a reaction product by impurities by generating plasma in an axial center of a glass tube by using laser beam for discharge ignition in plasma generation. CONSTITUTION: At first, a glass tube 1 is filled with a gas and then electricity is applied to a coil 1 to generate a magnetic field in the magnetic field direction 5. Then, a laser oscillator 8 is driven at the timing of plasma generation to radiate laser beam 10. The beam 10 is converged in a space surrounded with an antenna 4 and there plasma 7 is generated. After generation of the plasma 7, high frequency electric power is supplied to the antenna 4 from the high frequency electric power source 3 to excite waves in plasma 7. The wave is transmitted in the magnetic field direction 5 and aiming plasma is generated in the tube 2. Consequently, the inner face of the glass tube is hardly affected by the plasma and the components of the glass tube material and gases adsorbed in the glass tube wall hardly become impurities.

Title: Method and apparatus for continuous demagnetization and magnetic flaw detection
Inventor: NAGAKURA YOSHIYUKI
IPC: G01N27/82
Filed: 1992-10-13
Abstract: PURPOSE:To continuously execute a demagnetization operation and a magnetic flaw detection operation by a method wherein the magnetic flaw detection operation is executed while a magnetic field at an intensity or higher capable of performing a magnetization operation required for the magnetic flaw detection operation is reduced down to an intensity capable of performing the magnetization operation required for the magnetic flaw detection operation in the halfway of the demagnetization operation. CONSTITUTION:A thick plate 14 is passed by a stainless-steel roller 24 being a nonmagnetic substance, e.g. and by an idle roller 28. When the thick plate 14 is passed through a demagnetization place in which a magnetization coil 20 has been arranged, the thick plate is demagnetized by reversing a polarity while it is being moved away from the demagnetization place. A leakage flux from a defect part in the thick plate 14 in a magnetic flaw detection part installed in a position at about 80% of a saturation magnetic field is detected, and a magnetic flaw detection operation is performed to the thick plate 14 by a leakage flux sensor 30. In addition, when the demagnetized part of the thick plate 14 reaches a sufficiently distant place, a demagnetization effect is confirmed by, e.g. a gauss meter. Its result is recorded on a recording apparatus 32. When an array-type sensor is used as the leakage flux sensor 30, it is possible to detect a leakage flux in the width direction during the polarity reversal cycle of the magnetization coil 20.

Title: Image forming device
Inventor: HYO ICHIRO
IPC: G03G15/00
Filed: 1996-09-24
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device capable of restraining or preventing a surface staining in a specific width occurring in the vicinity of the image part derived from deterioration of the developer. SOLUTION: The device detects the peak value by detecting a density of a non-image part by a P sensor 7 (step 1 and 2), after producing a reference pattern on a photoreceptor drum 1. In the case detecting frequency of the peak value becomes twice, it is judged that the surface staining of a specific width is generated (step 3). The ratio Vsp1/Vsg between the density detection value Vsp1 of the surface staining generation part and the set output Vsg is judged whether smaller than 0.6 or not (step 4). In the case of smaller than 0.6, by judging that change of the developer is necessary, an agent replace display not shown in the figure on the operation display part of a copying machine is turned on (step 5).
