Title: Clad separator
Inventor: NOMURA SUEO
IPC: G21C19/307
Filed: 1983-04-23
Abstract: PURPOSE:To enhance the efficiency of separation while inhibiting the formation of the turbulent flow of a fluid, by providing a channel guide for introducing a cooling material for an atomic reactor along the rotating direction of a magnet from the upper part to the lower part of a reaction chamber, and enlarging the channel in the vicinity of the front end of said channel guide to decelerate the flow of said fluid. CONSTITUTION:The stream of a cooling material for an atomic reactor sent in through the fluid opening 7 of a reaction chamber 2 as shown in the arrow (a) is induced into channel guides 9A, 9B as shown in the arrows (b), (c) under a condition weakened by the presence of a baffle 27, etc., carried to the bottom of the reaction chamber 2 and then let flow along the ratating direction of a magnet as shown in the arrow (d) on the bottom. Hereon, since the cooling material for an atomic reactor is introduced into the wider reaction chamber 2, the stream of said cooling material changes into a gentle state in proportion to its separation from the channel guides 9A, 9B. In addition, the whirling-up of the clad is inhibited by providing baffles 10A-12A to inhibit turbulence, and the stream is curved by a channel-limiting guide 10 to introduce the fluid into a fluid outlet opening 8.

Title: Clad separator
Inventor: NOMURA SUEO
IPC: G21C19/307
Filed: 1983-04-23
Abstract: PURPOSE:To efficiently separate and remove clad for the improvement in the soundness of an atomic power generating plant, by subjecting a cooling material for an atomic reactor to an alternating magnetic field. CONSTITUTION:When a cooling material for an atomic reactor is sent through a fluid inlet 5 into a reaction chamber 2, clad existent under a floating condition is urged to move toward the vicinity of a magnetic pole, etc. against the viscosity of a fluid by the action of a magnetic field formed by each magnet. Hereon, the facing pole of each magnet 8A, 8B, 9A, 9B has different polarity to form a strong magnetic field. Hence, clad attracted by the resulting strong magnetic field, while being collected in the vicinities of inner and outer side walls 1a, 1b, is continuously moved riding on the progressive magnetic field along a peripheral direction while overcoming the fluid. In addition, when both supporting frames 10, 11 are rotated by a driving mechanism, a progressive alternating magnetic field is formed between facing poles adjacent to each other through the reaction chamber 2, since the adjacent poles have different polarities from each other. Consequently, the clad riding on said progressive magnetic field is efficiently collected.

IPC: C23C14/24
Filed: 1974-06-25
Abstract: In order to fabricate by MBE semiconductor devices, such as junction lasers and light modulators or varactor and impatt diodes, having relatively low series resistance one or more of the following three steps are executed: (1) on the substrate a high conductivity buffer layer is first grown having the same conductivity-type as the substrate; (2) beginning with the high conductivity layer and until all semiconductor layers of the device are fabricated, the growth process is made to be continuous; and (3) the substrate is heated just prior to the growth of the high conductivity layer and under excess pressure of any element in the substrate which has a relatively high vaporization pressure and which tends to evaporate from the heated substrate. Preferably all three steps are performed.

Title: Sheet ejector
Inventor: SHIRATORI TATSUYA
IPC: B65H29/22
Filed: 1986-03-28
Abstract: PURPOSE:To avoid traces of projections on a sheet during reverse feeding so as to prevent defective transfer at recopying by setting the reverse feeding end surfaces of kick off projections to make a gentle angle with respect to the periphery of flanges, while said projections being arranged on the flanges at both ends of a sheet ejecting roller. CONSTITUTION:A lower sheet ejecting roller has on both side thereof a flange 41 adapted form imparting nerve to a sheet S and formed with kick off portions having kick off projections 41b' for kicking off the trailing end of the sheet. Each of the kick off portions 41b also has a reverse feeding surface in form of a projection 41b'' extending at a gentle angle. Therefore, during forward feeding of the sheet S, it is kicked off by the projection 41b', and during reverse feeding, the sheet S is introduced by the gently inclined projection 41b'', causing generation of no abrupt steps in the sheet S. As there occur no traces of steps on the sheet S, defective transfer at recopying can be reduced, and further, vertical fluctuation of the sheet during reverse feeding is reduced, permitting stable reverse feeding.

Filed: 1995-03-30
Abstract: PURPOSE: To prevent the oil collected by a filter from dropping from a handle by providing the detachable handle below the center of the filter, and providing a larger opening than the width of the mounting part of the handle from the periphery of the mounting part of the handle to the upper part. CONSTITUTION: Oil mist sucked to a range hood is passed through the vent holes 6 of a filter 2c. In this case, the oil and the moisture are collected from the mist by the filter 2c. The collected oil flows along the surface of the filter 2c toward downward as increased. The oil flows along the part of the surface except the holes 6. If the hole 6 is small, the oil entirely flows irrespective of the part of the surface and the part of the hole 6 by the surface tension. When it flows to the vicinity above the handle 7 mounted downward, the flow is divided down to the right and left by the opening 8 of a triangular shape. At this time, since the opening 8 is larger than the handle 7, the oil does not flow to the handle 7 but flows to an oil receiver provided under the filter 2c.
