IPC: G03F1/36
Filed: 1986-05-10
Abstract: PURPOSE:To form a polygonal pattern like a square without hindrance by forming a polygonal pattern forming part with plural aperture parts which are radially extended from the center toward corner parts. CONSTITUTION:A light shielding film 3 consisting of chromium or the like is selectively formed on the surface of a transparent plate 2 to obtain a mask 1 for exposure, and a pattern for exposure is formed with parts where the light shielding film 3 is not formed. In case of forming a minute polygonal pattern approximating the limit of resolving power, the great influence of the diffraction phenomenon of light is used and a pattern forming part 4 is formed with plural aperture parts 5 radially extended to the corner parts of the polygon. When exposure is performed with the mask 1, isometric lines of luminous intensity of the light passing the pattern forming part 4 have a polygonal luminous intensity distribution by diffraction, and a minute polygonal pattern is accurately formed.

Title: Sealed lead-acid battery
Inventor: ONISHI KAZUHIKO
IPC: H01M10/10
Filed: 1993-04-08
Abstract: PURPOSE:To provide an inexpensive sealed lead-acid battery having excellent battery performance by using a positive electrode grid composed of lead- antimony type alloy, and using silica fine powder and microporous acidproof synthetic fiber. CONSTITUTION:Lead-antimony type allay is used in a positive electrode grid, and a corrosion layer created on an interface between the positive electrode grid and an active material is made porous, and bonding between particles is strengthened, and early capacity deterioration or falling of the active material can be prevented, and a short circuit caused by elongation of the grid can be also reduced. Silica fine powder arranged in a clearance between a positive electrode plate and a negative electrode plate and microporous acidproof synthetic fiber adsorb antimony, and prevents the movement of the antimony to a negative electrode from a positive electrode. As a result, since a drop in hydrogen overvoltage by the antimony is eliminated, water decomposition is not increased, so that characteristics such as maintenance free and water non- supply being the largest characteristic of a sealed lead-acid battery is not spoiled.

Filed: 1983-06-17
Abstract: In a continuous-casting method molten steel is continuously introduced into a continuous-casting mold to form therein a strand having a free surface in the mold, a pair of relatively wide faces, and a pair of relatively narrow faces. The mold and the steel therein are continuously cooled to externally solidify the molten-steel strand while leaving same internally molten and the externally solid and internally molten strand is continuously withdrawn from the lower end of the mold. The core of the strand solidifies increasingly as it moves from the mold and terminates downstream of the mold at a pool bottom. At each of a plurality of locations spaced apart about 1 m to 2 m longitudinally along the strand between the mold and the pool bottom a respective magnetic field is formed with the fields passing through the strand from between about 3 m to 7 m beneath the free surface to about 2 m to 6 m from the pool bottom. These fields are displaced transversely of and generally parallel to the side faces of the strand with each field moving opposite to the adjacent field or fields so as to magnetically transversely and oppositely displace respective portions of the molten core of the strand.

An optical filter 107, which is used as an pumping light separator, is installed between the fibers 101 and 104. Thereby, as the 1.48mum band pumping light is hardly incided in the fiber 101, the 1.48mum band pumping light can be prevented from being amplified by the 0.98-mum band pumping light. Accordingly, even at the time of a high output, an optical fiber amplifier with excellent NF characteristics and a light signal transmission system can be realized.

Filed: 1982-06-25
Abstract: PURPOSE:To minimize the power consumption for power steering and effect energy saving by operating an oil pump only when a large steering force is required and without operating said pump when a car is stopped and there is no need of steering. CONSTITUTION:When a car starts to run, a car-speed sensor 100 genrates speed signals and a timer 200 generates motor driving signals regardless of steering operations, turning a switch 7 on. An F-V convertor 220 generates a DC voltage corresponding to the speed signals, but during the time when the speed signals are below the determined value, a comparator 240 does not generate motor cut- off signals, a switch 6 is turned on and a motor 3 continues to operate. When the determined speed is over, the voltage supplied from the F-V convertor 220 to the comparator 240 exceeds its set value causing the comparator circuit 240 to generate motor cut-off signals. Thereby the switch 6 is turned off and the motor 3 stops operating without the electric power being provided.
