Title: Wet treating device
Inventor: NISHIMURA SUKEYUKI
IPC: G03F7/30
Filed: 2001-04-24
Abstract: PROBLEM TO BE SOLVED: To provide a wet treating device having a liquid draining mechanism which can efficiently drain a treating liquid left on a substrate. SOLUTION: In the wet treating device, a substrate having a stripe pattern films thereon is treated chemically or physically with a prescribed liquid and the liquid left on the substrate is drained being blown out by long liquid drain nozzles having slit-like air outlets while the substrate is conveyed in the direction orthogonal to the stripe pattern. This device comprises at least two liquid drain nozzles which are reversely inclined in the direction orthogonal to the conveying direction A of the substrate G. Since the liquid is drained in two oblique directions so as to be swept out toward both sides of the substrate G, the treating liquid left on the substrate can be efficiently drained from the substrate, which eliminates problems caused by the liquid in the wet treating left on the substrate.

IPC: H01P1/383
Filed: 2001-04-26
Abstract: PROBLEM TO BE SOLVED: To provide a nonreciprocal circuit element that has superior electric characteristics at all temperatures, and to provide communication equipment and a method of manufacturing the circuit element. SOLUTION: The electric characteristics of an isolator 1 composed of an upper case 8, a lower case 4, a center electrode assembly 13, a permanent magnet 9, etc., is adjusted by a magnetization adjusting method. Namely, a permanent magnet 9 contained in the isolator 1 is magnetized by impressing a strong external magnetic field upon the isolator 1. Thereafter, the magnet 9 is demagnetized by impressing a weak external magnetic field upon the isolator 1 in the direction opposite to the direction of magnetization. Then whether or not the low-frequency end and high-frequency end of the pass band of the isolator 1 are within the acceptance/rejection criteria is confirmed by measuring the electric characteristics (at least one of input- output reflection loss, insertion loss, and isolation) of the isolator 1 at a room temperature (about 25 deg.C).  When the ends depart from the reference values, the permanent magnet 9 is further demagnetized by impressing an external magnetic field which is a little stronger than that impressed last time upon the isolator 1 in the direction of demagnetization.
