Abstract: PURPOSE:To enhance accuracy by simple constitution, by constituting an exciting side filter of two kinds of ones different in a wavelength and mounting both filters to a support plate to perform the chopping of exciting light. CONSTITUTION:Filters F1, F2 are mounted to both end parts of a support plate 5 which is reciprocatingly movable in the direction right-angled to exciting light EX.

The reciprocating movement of the plate 5 is performed by utilizing the rotation of a motor 7. That is, a disc 8 is fixed to the shaft of the motor 7 and a crank lever 6 is mounted between a pin 9 and one end of the plate 5. When the disc 8 and the pin 9 are rotated with the rotation of the motor 7, the plate 5 is pulled or pushed through the lever 6 and a guide corresponding to the position of the pin 9 and moves along a linear route cyclically and reciprocatingly as shown by an arrow.

IPC: H01L21/302
Filed: 1986-05-13
Abstract: PURPOSE:To improve step-coverage in second or upper multilayer interconnections, by forming through holes in the process of etching-back for forming a flat semiconductor surface. CONSTITUTION:An oxide layer 2 is formed on a Si semiconductor substrate 1, and then a first interconnection layer 3 having a prescribed pattern is formed thereon. A second insulating material layer 4 is piled moreover, then covered with a posi-resist 5. Portions in the layer 5, which face the layer 3, are then opened to form prescribed patterns, and the resist 5 is removed by anisotropic etching. In this process, openings 6 are formed in the layer 4 via the openings formed in the layer 5. Besides, a third insulating material layer 7 is piled on this surface of the layer 4, to obtain a flat surface. Then, covered with a posi- resist layer 8 again, openings 9 larger in diameter than the openings 6 are formed by anisotropic etching. Because cross sections of the openings 9 are shaped in steps, step-coverage in a second interconnection layer 10 formed thereafter can be improved.

Inventor: UKAI MASAKI
IPC: H01F7/16
Filed: 1998-04-17
Abstract: PROBLEM TO BE SOLVED: To reduce a clearance with the movable iron core of a pipe, to reduce hysteresis and to precisely control a proportional position, by setting the inner diameter of a non-magnetic pipe to be a value larger than the inner diameter of a magnetic pipe. SOLUTION: The inner diameter of a non-magnetic pipe 52 is set to be a value larger than the inner diameter of a magnetic pipe 53. The outer diameter of the non-magnetic pipe 52 is set to a value similar to the outer diameter of the magnetic pipe 53. When the magnetic pipe 53 is dislocated from the non-magnetic pipe 52 in the direction of a radius owing to friction press-contact, interference between the magnetic pipe 53 and the non-magnetic pipe 52 in a movable iron core 4 can be avoided even if the outer diameter of the movable iron core 4 is set to a value which is almost equal to the inner diameter of the magnetic pipe 53. A sliding ring is installed at the outer periphery of a movable iron core 4 and the sliding resistance of the movable iron core 4 against the magnetic pipe 53 is reduced.  Thus, a clearance between the pipe 5 and the movable iron core 4 is made small, hysteresis is reduced and a proportional position is highly precisely controlled.
