Title: Microwave circuit board
Inventor: TAWARA KAZUHIRO
IPC: H01P3/08
Filed: 1991-03-23
Abstract: PURPOSE:To reduce the area size of a microwave circuit board by forming a groove to a dielectric board between transmission lines so as to reduce the static capacitance between the transmission lines, thereby reducing the coupling between the transmission lines. CONSTITUTION:The creepage distance of a dielectric board 1 between transmission lines 2, 3 is prolonged by a slot 4, the static capacitance between the lines is reduced and the coupling between both the transmission lines 2, 3 is weakened. Thus, the coupling between both the transmission lines 2, 3 is decreased without increasing the interval between both the transmission lines 2, 3 and the area size of the microwave circuit board is reduced. Moreover, the effect of reducing the coupling between both the transmission lines 2, 3 is increased more when the dielectric constant of the board 1 is high. Furthermore, the coupling between the transmission lines is reduced more by changing the depth of the slot and the shape of the bottom face.

Title: Scanning electron microscope
Inventor: TSUNO KATSUSHIGE
IPC: H01J37/147
Filed: 1996-04-05
Abstract: PROBLEM TO BE SOLVED: To provide a scanning electron microscope by which secondary electron detecting efficiency can be improved. SOLUTION: Secondary electrons are generated by radiating primary electron beam to a specimen and the secondary electrons are restricted by a magnetic field of an objective lens 1 and proceed upward while moving spirally inside the objective lens 1. At that time, the magnetic field generated by a solenoid coil 6 works as to converge the secondary electrons in the direction of the optical axis and takes a role as to prevent the secondary electrons moving upward in the objective lens 1 from being diffused, coming into collision against the wall part of the objective lens 1, and being absorbed in the wall. Voltage as high as about 60V is applied to an electrode 7. As a result, attributed to the electric field in the tip end of the truncated cone-shape electrode 7, the secondary electrons emitted out of the specimen 5 at angles in a wide range can be converged in the direction of the optical axis and the secondary electrons are efficiently led in the upper part along the optical axis of the objective lens 1.
