Title: Heat accumulator
Inventor: MIZUNO TOMOKIMI
IPC: F02G1/057
Filed: 1984-09-28
Abstract: PURPOSE:To improve the performance of a heat accumulator by compressing the piled parts of the wire stocks of wire meshes in the piling direction and increasing the number of laminations of said wire meshes in a cylinder body, in a heat accumulator in which a number of wire meshes are laminated in said cylinder body. CONSTITUTION:A heat accumulator is formed by laminating a number of wire meshes 1 consisting of wire stocks, in a cylindrical body. In this case, the piled parts of the wire stocks of the wire meshes 1 in which said wire stocks having circular section are woven, are compressed by rolling in the piled direction, forming flat face parts 3. And, the section of the wire stocks in the flat face part 3 are formed into nearly a rectangular shape, and the distance l2 between axes of the wire stocks is made small. Thereby, since the dimension l2 of each of the wire stocks in the piled direction can be reduced, the number of laminated layers of the wire meshes 1 can be increased for a cylindrical body having the same volume, improving the performance of a heat accumulator.

Title: Exposure device
Inventor: TAKAMOTO KIICHI
IPC: G03F7/20
Filed: 1986-08-29
Abstract: PURPOSE:To cut down the period of exposure by a method wherein the progressing direction of the pulse light emitted by the source of light is brached into a plurality of directions, they are made to irradiate at the places of the diffusion devices having different light path lengths and light path outputs, or the light is made incident by differentiating the angle of incidence. CONSTITUTION:The length of light path of a light path 17 is made longer by 3 m or more from that of a light path 18. The light makes progress about 0.3 m in 1 ns, and as there is the difference in the length of light pass of 3 m or more in this example, the laser beam of the light path 17 reaches a diffusion plate 11 slower by 10 ns or more than the laser beam of the light path 18. Accordingly, the emitted light of the laser beam coming from the source of light reached the diffusion plate 11 in two times having the interval of time of 10 ns or more, and the phase of the light reaching the mask surface changes momentarily by passing the rotating diffusion plate 11. As a result, the light having different phase is made to irradiate on the mask surface 200 times per second, and the time of exposure can be reduced to one second which is one half of the time required before.
