Filed: 1997-08-28
Abstract: PROBLEM TO BE SOLVED: To mass produce a thin pole plate and prolong the life of a battery using this pole plate by forming a current collector of the pole plate through weaving, knitting, paper making processes or mixed paper making process of a conductive tin dioxide fiber. SOLUTION: A current collector is formed as a pole plate having a thickness of about 2.0 mm or less by weaving, knitting or paper making processes of a conductive tin dioxide fiber, having a specific resistance of 10<2> Ω.cm or less. Otherwise, it is formed by the mixed paper making process of the conductive tin dioxide fiber with a synthetic pulp or polyolefin base fiber.

A porous current collector can be continuously manufactured by weaving, knitting or paper making processes, without requiring a perforating work. When this current collector is used, a large effect can be provided in a thin pole plate, since the conductivity can be imparted to the whole active material because of the extremely fine conductive network.

IPC: H05K1/18
Filed: 1990-09-18
Abstract: PURPOSE:To prevent occurrence of resin crack against a stress at automatic insertion by providing >=1 notchs to a side ridge of a leg of a lead terminal to be clinched. CONSTITUTION:A main body of an electronic component A is chucked by an automatic insertion machine, lead terminals 1, 2 are inserted to holes 6a, 6b of a printed circuit board 6, a pusher is used to depress an upper side of the electronic component A, legs 1a, 2a of the lead terminals 1, 2 projected downward to the board 6 are partly cut off and the lead terminals 1, 2 are clinched outward simultaneously.

Title: Projection exposure system and manufacture of device thereby
Inventor: SUZUKI MASAYUKI
IPC: G03F7/20
Filed: 1995-09-01
Abstract: PROBLEM TO BE SOLVED: To obtain a projection exposure system which is capable of preventing aberration caused by deformation of a beam splitter due to gravity when the beam splitter is thin by a method wherein a normal of the surface of the beam splitter is set nearly vertical to a direction of gravity or made to intersect the direction of gravity at right angles. SOLUTION: A divergent light flux projected from a point located on a reticule is made to penetrate through a beam splitter 3 passing a lens 2. A transmitted light flux passes through a first quarter wavelength plate 4 and then travels reversely as reflected from the concave surface 5a of a concave mirror 5. Furthermore, the light flux traveling reversely is made to travel as turned in a traveling direction by an angle of 90 deg. to pass through the quarter wavelength plate 4 again. Furthermore, a light flux is made to pass through a second quarter wavelength plate 6 and turned into planar polarized light, and the planar polarized light is made to impinge on a second lens group 7 to form an image on a wafer 910.  The beam splitter 3 is less than 10mm in thickness, but, a normal line of the surface of the beam splitter 3 is set vertical to the direction of gravity, so that the beam splitter 3 is hardly deformed by its own weight. Therefore, a projection exposure system is capable of preventing aberration caused by deformation of a beam splitter due to gravity.
