Title: Riser for commutator
Inventor: KOJIMA MINORU
IPC: H01R39/04
Filed: 1983-11-21
Abstract: PURPOSE:To reduce the mounting interval of risers for a commutator by displacing the center of the riser having a large thickness in a lateral direction toward one of the longitudinal directions of an armature coil. CONSTITUTION:A riser for a commutator is composed of both slender ends 8 in the longitudinal directiin of an armature coil, a central portion 9 having the same sectional area as the both ends 8 and formed so that the thickness of the plate is double of the thicknesses of the both ends 8 and one longitudinal end has the same plane as the longitudinal end of the both ends 8, and a coupler for coupling them. Since the central portion 9 is displaced so that the longitudinal one end of the armature coil forms in the same plane as the end faces of the both ends 8, the central parts 9, 9' do not oppose to each other when adjacent risers 7' are mounted oppositely.

Abstract: PROBLEM TO BE SOLVED: To provide an electrophotographic type image forming device simultaneously compatible with the higher harmonic current regulation and the power source voltage fluctuation regulation. SOLUTION: At the time of supplying power from an AC power source 1 to a toner fixing heater 2, a temperature sensor 4 detects the heater temperature, and if the heater temperature is below a specified temperature of 150 deg.C for instance, a phase angle is maintained for 600 ms so that a current conducting time is 60% of the total operation time before a soft start control is initiated with full turn on. On the other hand, if the heater 2 temperature at the time of power feeding is higher than a specified temperature t, a phase angle is kept for 400 ms at a value corresponding to provide a current conducting time of 60% of the total operation time before the soft start control is performed with full turn on. In either case of the above, the power is continuously supplied to the heater 2 after the full turn on.  Then, in the case the heater temperature detected by the temperature sensor 4 and a temperature detecting circuit 5 rise to a predetermined temperature, for instance. 200 deg.C, the power supply to the heater 2 is stopped.

Abstract: PURPOSE:To uniformly control ion energy by performing treatment of a base plate in the resonance point of an electron cyclotron in a plasma generation chamber and impressing high-frequency bias voltage having the specified frequency to an electrode provided with the base plate. CONSTITUTION:The gas to be treated is plasmaized by utilizing both an electric field which is generated by microwave 8 in a plasma generation chamber 1 and the resonance phenomena of an electron cyclotron which are caused by a magnetic field orthogonal to this electric field. A base plate 15 is provided and treated extremely near to a resonance point 9 of an electron cyclotron in this plasma, namely in the part of a range of about + or -100 gauss.
