IPC: H01M8/06
Filed: 1987-11-11
Abstract: PURPOSE:To prevent the clogging of the title steam reformer due to carbon deposition by extending the steam reforming catalyst bed toward a raw material supply chamber in the reformer wherein a double tube-structure reaction tube having the catalyst bed in the gap between the inner and outer tubes is arranged in a heating chamber. CONSTITUTION:The inside of a heating furnace is separated by a partition plate 30 into the raw material supply chamber and the heating chamber, and the double tube-structure reaction tube 20 consisting of the inner tube 1 and the outer tube 2 and having the steam reforming catalyst bed A in the gap between both tubes is supported by the partition plate 30 and arranged in the heating chamber.

IPC: F25C1/24
Filed: 1987-11-10
Abstract: PURPOSE: To make an ice block of substantially perfect sphere easily and surely by providing a hemispherical ice making cup and a set of two ice making covers. CONSTITUTION: A spherical face of small radius is formed through combination of spring charged ice making covers 15, 15, and an ice making cup 14.

IPC: G02B6/42
Filed: 1988-11-11
Abstract: PURPOSE:To facilitate the optical axis adjustment for cutting down cost by a method wherein a transparent sheet comprising the central part and the peripheral part in different optical thickness is inserted between a semiconductor laser and a lens system. CONSTITUTION:Within a coupling system wherein radiation from a laser diode(LD) pellet 1 is focussed by a lens 2 to be entered into an optical fiber 3, a transparent sheet 4 is inserted between the pellet 1 and the lens 2. The transparent sheet 4 comprising the central and the peripheral part in different thickness, the image forming positions of the beams passing through the central part and those passing through the peripheral part are slipped from each other in the axial direction. Through these procedures, the couple loss is leveled off despite the changes in the intervals between the pellet 1 and the lens 2 so that the LD modules for short interval subjected to the least variability regardless of no adjustment of the LD pellet 1 in the direction of optical axis may be manufactured. Consequently, the adjustment of optical axis as well as the components can be facilitated thereby cutting down cost.
