Title: Exposure device
Inventor: ECHIZEN YUTAKA
IPC: H01L21/027
Filed: 1984-09-15
Abstract: PURPOSE:To enable the control of proper exposure by a method wherein a light receiving means which receives part of energy beams coming out of the energy source split by an amplitude splitter with an aperture substantially of the same shape as that of the sensitive substance or of similar form is provided on a plane conjugated with the sensitive substance placed in a path split by a splitter arranged between the energy source and the original plate. CONSTITUTION:A measured light flux L2a and an exposure light flux L1a are split in amplitude via half mirror 4a and are in optical conjugation, then becom ing the same as the light flux conditions. Since light fluxes L2b and L1b and light fluxes L2c and L1c are also in the same case, a region M1 on a transcrip tion surface 6 and an aperture mask M2 of the light receiving means 7 come into an optical conjugated relation. As a result, even when the light source 1 varies in position in directions of arrows DELTAX, the ratio [DELTA(L1a-L1c)/DELTA(L2a-L2c)]0 of the luminance variation DELTA(L1a-L1c) on the transcrip tion surface 6 to the luminance variation DELTA(L2a-L2c) in the light receiving means 7 becomes constant.

Title: Manufacture of water-proof optical cable
Inventor: FUKUMA MASUMI
IPC: G02B6/44
Filed: 1986-08-19
Abstract: PURPOSE:To reduce the used amount of powder of an electrostatically charged water-absorptive swelling material and to prevent the powder from being dispersed in air by sticking the powder on an optical fiber core stack body. CONSTITUTION:The powder 1 of the water-absorptive swelling material supplied from a hopper 2 to a conveyer is carried to under a spacer 7 by a belt 4. A conductor 6 fitted to the internal surface of a cover 9 made of an insulating seal is applied with a voltage from a device 5 as well as the belt 4. When the powder 1 is a dielectric with a high resistance value, polarizing operation is caused by an electric field between the spacer 7 and belt 4 to generate positive charges on the powder 1 and negative charges on the side of the belt 4. Then when negative charges under the powder 1 are neutralized by the potential of the belt 4, electric force which attracts the powder 1 to the side of the spacer 7 is generated and the powder 1 sticks on the grooved spacer 7 where optical fibers are stacked.

Filed: 1983-10-19
Abstract: PURPOSE:To detect a liquid level with rapid responsiveness by detecting optically an up-and-down movement of a float made of foamed body in a guide tube set in the vicinity of a liquid helium level. CONSTITUTION:The float 4 made of expanded polystyrene is packed in the guide tube 3a set in the vicinity of the liquid level 2 of a liquid helium 1, and a pair of optical fibers 5a, 5b are arranged opposingly at the liquid level X to a wall surface of the tube 3a. The light emitted from an electricity-to-light converter 7 is emanated from an emanating end 6a through the fiber 5a, and detected by an electric converter 8 from an incident end 6b through the fiber 5b. If the float 4 is lowered together with the level 2 and detained by a stopper 10, the light is intercepted and the output of the converter 8 disappears. Consequently, the liquid level is detected with rapid responsiveness.

IPC: H01L29/78
Filed: 1989-07-28
Abstract: PURPOSE:To eliminate resistance increase, disconnection, and imperfect connection of a bus line, and improve manufacturing yield, by a method wherein, when a gate insulating film and a semiconductor layer become interlayer insulating films between a first bus line and a second bus line, the upper layer surface is made to retire from the lower layer surface by a range from 1/100 to 20 times film thickness at an etching step-difference. CONSTITUTION:A second bus line 7' (e.g. drain bus line) and a first layer 12 of the second bus line terminal part to be connected with an external circuit are connected through an etching step-difference of a gate insulating film 3. At the etching step-difference part of the gate insulating film 3, a normaly tapered inclination type step-difference is constituted, in the manner in which the upper layer surface of the gate insulating film 3 is made to retire from the lower layer surface by a range from 1/100 to 20 times the film thickness (d). Since the etching step-difference of the gate insulating film composed of a silicon nitride film or the like is made gentle by constituting a normal taper, the resistance increase and the generation of defect like disconnection of the bus line can be prevented, and the manufacturing yield can be remarkably improved.

Abstract: PROBLEM TO BE SOLVED: To sufficiently reduce the cost of a semiconductor substrate where a single crystal semiconductor layer is provided on a base substrate. SOLUTION: By injecting the ions of hydrogen gas into a lamination substrate 25 consisting of a high-quality single crystal silicon substrate, a defective layer 26 for releasing is formed on the surface while a single crystal thin-film layer 25a is secured. Then, the lamination substrate 25 is laminated to a base substrate 22 consisting of a single crystal silicon substrate with poorer quality than the lamination substrate 25 via an insulation film 23 and is successively released by the defective layer 26. After that, a high-temperature annealing and the surface polishing of the release surface are performed, thus obtaining a semiconductor substrate 21 with a single crystal semiconductor layer 24 on the base substrate 22 via the insulation film 23.  The lamination substrate 25 through a release process is repeatedly used by flattening the surface and a new single crystal silicon with the same material is laminated to form the new lamination substrate 25 when the thickness is reduced to a specific value or less.
