Title: Transformer winding
Inventor: NONAKA SHIGEO
IPC: H01F27/28
Filed: 1982-07-01
Abstract: PURPOSE:To uniformly cool each winding section with an insulating medium flowing through cooling passages by a construction wherein radial widths of inner and outer axial cooling passages between the adjacent spacers is set to be gradually increased from both spacer sides to the center part therebetween. CONSTITUTION:An outer insulating tube 12 is shaped into the form of a polygon having a corner 12a at each center between adjacent spacers 4, 4, while an inner insulating tube 11 is shaped into the form of a polygon having a corner 12a at the mounting part of each duct rail 8. Radial widths w11, w12 of inner and outer axial cooling passages 16, 17 are set to be gradually increased toward the centers, and the cooling passage 17 has the width larger than that of the cooling passage 16 to render smaller flow resistance. When the transformer oil is made to flow into the transformer winding provided with the cooling passages 16, 17 thus structured so as to cool each winding section 3, temperature distribution is uniformed in the winding section 3 and also the maximum temperature is lowered.

Title: Exposure apparatus for forming pattern
Inventor: KITAYAMA TOYOKI
IPC: G03F7/20
Filed: 1984-06-04
Abstract: PURPOSE:To enable a fine pattern to be formed at a high speed and thereby to permit an improvement in productivity of an integrated circuit, by turning ON a light source when the relative positional relationship between a luminous flux and a substrate to be exposed to light reaches a preset one. CONSTITUTION:A wafer 7 retained on a stage is continuously moved in the direction of X at a rate of 100mm./sec. After chips 9 and 10 have been subjected to light exposure and when the positional relationship between the wafer 7 and a luminous flux 5 reaches one such as that illustrated, an excimer laser is made to emit a laser beam by a trigger from a position detection signal processing unit to sensitize a photoresist film 6. In this arrangement, an excimer laser which is a strong far-ultraviolet light source is employed, and exposure is effected by light in the shape of a pulse for a short period of time while a substrate to be exposed such as a wafer and the luminous flux passing through a mask or reticle are continuously moved relative to each other. It is therefore possible to form a fine pattern at extremely high speed and to greatly improve the productivity of an integrated circuit substrate.

Title: Tempered foam glass
Inventor: IIZUKA KAORU
IPC: C03C14/00
Filed: 1989-05-08
Abstract: PURPOSE:To improve flexural strength, tensile strength of tempered foamed glass by an easy method by incorporating a material with specific stainless steel wire having specific diameter and specific length in a specific ratio. CONSTITUTION:A material is incorporated with 1.0-6.0wt.% stainless steel wire having 0.1-0.5mm diameter and 5-30mm length to give tempered foamed glass. Consequently, foamed glass can be readily reinforced. When the diameter of the wire is <0.1mm, reinforcing effect is insufficient, the wire is mutually entangled during blending with glass fine powder and the wire is not uniformly dispersed into the glass fine powder. When the diameter of the wire is >0.5mm, cracks caused by difference in coefficient of thermal expansion between the wire and the foamed glass are liable to occur in product during cooling. When the length of the wire is <0.5mm, reinforcing effect is reduced. When the length of the wire is >30mm, the wire is liable to bend and consequently the reinforcing effect is diluted to reduce dispersibility of wire.
