Patent JP-H03218414-A (JP)
Title: Electromagnetic flowmeter
Inventor: KOSHIMIZU ATSUSHI
IPC: G01F1/58
Filed: 1990-01-24
Abstract: PURPOSE:To shorten distance between coils and to improve the efficiency of a magnetic circuit by providing the three pairs of coils on the outer periphery of a circular passage while equally dividing the circumference into three parts. CONSTITUTION:On the outer periphery of a pipe P equipped with the circular passage in the internal part while insulating the inner surface, coils C1, C2 and C3 are arranged at the positions dividing the circumference into three parts equally at 120 deg. and one coil is excited so that the magnetic pole is different from those of the other two coils. As shown figures (a), (b) and (c), when an exciting pattern is successively moved in the order of C1, C2 and C3 for the coil equipped with the different magnetic pole from those of the other two coils, a flow rate signal is proportion to the velocity of fluid F and the strength of magnetic flux B is detected from electrode T1, T2 and T3 arranged among the three coils. Thus, the distance between coils is shortened and a magnetic field to be generated to the same exciting current is increased.

Title: Suppression of arc in plasma processing system
Inventor: JIERARUDO TSUEYAO IN
IPC: H01L21/302
Filed: 1995-01-30
Abstract: PURPOSE: To prevent a secondary plasma from occurring by limiting at least one portion of any gap or gas circulation path inside an insulation structure body so that it is smaller than a threshold thickness for generating the secondary plasma. CONSTITUTION: A flange 28 is extended from a dielectric insulator 26 between a clamping ring 14 and a screening structure body 18. A plasma excitation field nearly does not exist in a region 30 that is adjacent to the outer end face of the clamping ring 14, thus preventing the secondary plasma from occurring in the region 30. Therefore, when the flange 29 changes a gas circulation path direction to the inside of the region 30, an ionized gas flowing through a channel 22 is weakened inside the region 30, thus remarkably reducing the possibility of connecting a shielding structure body 18 and a cathode support structure body 12 electrically and hence preventing the secondary plasma from being generated.
