Title: Tunnel josephson junction
Inventor: HIDAKA MUTSUO
IPC: H01L39/22
Filed: 1987-01-05
Abstract: PURPOSE:To lessen the effect of an internal stress of an electrode film and improve the breakdown strength toward heat treatment by forming a lower electrode that is composed of the first superconducting layer where the internal stress is low and the second superconducting layer having a structure that is thinner and more precise than that of the first one. CONSTITUTION:A lower electrode is composed of two layers, one of which is located at the lower side of its electrode and is a film (first superconductive layer) 12 where the internal stress is low and the other is located at the upper side of the electrode and has the high internal stress per unit sectional area but has a more precise film (second superconductive layer) 13. The precise film 13 of the upper side is formed to have a structure that is thinner than that of the film 12 having the low internal stress. The internal stress in the film is so in proportion to the film thickness that even though the internal stress of the second superconductive layer 13 per unit sectional area is high, the entire internal stress of the lower electrode itself can be held low, so long as its film thickness is thin. In this way, the lower electrode where its internal stress is low and its precise structure causes a part that is in contact with a metal forming a tunnel barrier layer to make its integranular diffusion difficult can be used and its utilization enables this device to be independent of the internal stress and to obtain an artificial barrier junction having the high breakdown strength toward heat treatment.

Title: Process for preparing powder or granular material
IPC: C03C17/06
Filed: 1944-01-07
Abstract: 574,124. Coating particles. LUMB, C. F. Jan. 7, 1944, No. 351. [Class 56] [Also in Group II] In a method of preparing for spraying a powdered or granular base substance coated with another substance which has a relatively low fusion temperature, the base material is heated sufficiently to fuse the coating material and to cause the latter to adhere to the base particles and form a surface coating thereon when the two are brought into contact with one another. When the thus coated particles are sprayed, the surface coating acts as a binder to cause the particles to become adherent to one another. Glass may be coated with zinc by heating the glass particles to a temperature not less than 420‹ C. in a revolving furnace and introducing a quantity of zinc in the form of pellets. Other examples of the base material include graphite, tungsten, carbide and siliceous substances which may be coated with tin, lead or synthetic resins.

Title: System for cutting pieces from a travelling strip of sheetmaterial
IPC: B23D36/00
Filed: 1974-01-07
Abstract: 1462801 Sawing apparatus; cutting by laser beam MITSUBISHI RAYON CO Ltd 7 Jan 1974 00603/74 Headings B5L and B4B [Also in Divisions B8 and C1] A method for obtaining at least two collections of sheets of different respective lengths by transversely severing a strip of the sheet material having faults at random locations therealong, comprises determining the length of each usable portion between adjacent faults, calculating the combination of numbers of sheet pieces of each of said lengths which gives a combined length closest to but shorter than the length of each usable portion, and severing each said usable portion into said calculated sheet lengths to remove said faults and minimize loss in the usable portion. As described a strip 10, Fig. 1, is conveyed past a measuring wheel 11 and fault detectors 13, 14 which together supply a signal to a computer 15 when a fault is detected in the strip. The computer thus determines the length of each usable portion of the strip and using sheet lengths preset into counters 17a, 17b, 17c then determines the combination of numbers of sheets of each preset length to minimize waste of the usable portion. The computer then causes a severing device 21 to cut the usable portion into the determined sheet lengths. The device 21 comprises a cutter, e.g. 22a, moved transversely of the strip by a carriage 23, which is carried by a frame 24 moved parallel with the strip and, during cutting, at the same speed thereas by an electrohydraulic pulse motor 20, so that the strip is severed right angularly. In the case where it is desired to cut a length from the strip less than the minimum length determined by the time taken for the severing device to carry out a cycle of cutting and return strokes, two severing devices may be provided, which are operable independently.  The or each severing device may include plates for clamping against the strip during cutting, and the plates may be carried by boxes which enclose the cutting tools and are connected to dust extraction ducts. When the strip is of plastics or plywood the cutting devices may be rotary saws. For a glass strip diamond cutters are used. Alternative cutter means are water jets and laser beams.

[Also in Group V] A self-feeding brush of the kind in which washing liquid is fed into the hollow interior of the brush body through a feed connection and wherein the stock of the brush is in two parts, the upper part having the feed connection and the lower part being adapted to carry tufts of bristles and having a number of holes for the flow of the liquid between the tufts, is manufactured by moulding the upper and lower parts of the brush-stock from the same elastic rubber material by partial vulcanization in a mould after which .the tufts of bristles are inserted in the lower part of the stock, then the two parts are roughened at their contacting edges which are next spread with vulcanizable rubber solution and finally the parts are pressed together in a vulcanizing mould and given a final vulcanization. Preferably, in the final vulcanization, the mould is so formed that the bundles of bristles are surrounded by an envelope of heat resistant and heat insulating material such as asbestos whereby the bristles are guarded against damage by the heat. It is preferred to provide the contacting edge of one part of the stock with an annular tenon to engage a corresponding groove or recess in the edge of the other part. The brush shown which is circular in shape comprises an upper part a provided with a feed connection b and a dove-tail tenon d on its perimeter engaging a correspondingly shaped groove g in the lower brush part f, the latter having holes i for passage of water between tufts h.

[Class 2 (iii)] In the sulphation of ethylene, the acid and gaseous ethylene are passed in the same direction through a reactor having a reaction zone long in relation to its cross sectional area at a velocity greater than the " critical velocity." The latter is defined as that velocity above which there is a sudden drop in back pressure, due to the liquid acid being forced to spread as a thin film over the whole inner surface of the tubular reactor. The reactor may consist of horizontal or vertical coils or straight tubes coupled by return bends. The acid should preferably flow upwards when the coils are vertical but if jacketted tubes are used they should be inclined to the'horizontal. The tubes may be air or water cooled or the reactor may consist of tubes of gradually increasing diameter, the heat development being greatest at the inlet. Alternatively the sulphation may be effected in a multi-stage unit comprising a number of reactors in each of which the reactants flow in the same direction, but in the unit as a whole the ethylene and sulphuric acid flowing in counter current, the ethylene being treated in the early stages with partly esterified acid withdrawn from a later stage and only in the last stage with fresh acid.
