Title: Silicon carbide crystals and processes and furnaces for making them
IPC: C30B25/00
Filed: 1960-01-01
Abstract: <PICT:0927466/III/1> Crystals of hexagonal silicon carbide are prepared by heating Si and one or more carbon, preferably graphite, pieces spaced therefrom to 2300 DEG -2500 DEG C. in an inert gas atmosphere containing not more than 1 mol. per cent N2, one or more heat sinks existing at a distance from the carbon pieces not less than the maximum dimension of the largest crystal to be formed, and in directions substantially normal to the carbon surface at the junctions with each crystal.  The crystals have "n" and/or "p" conductivity and have two faces substantially parallel to each other to within 1 degree, the maximum measurable length on either of these faces being not less than 1,6 mm., and the perpendicular distance between these faces is 0,013-2,5 mm. The content of components other than Si and C is not more than 1000 parts per million and the specific resistance is from 0,01-1000 ohm-cm. at 20-25 DEG C. Silicon 25 is placed in annular graphite crucible 21 supported on graphite bars.  Graphite bars support cylindrical graphite sleeves 31-35 above crucible 21.  The whole is contained in graphite container 13 having cover 14 with central hole 15 and graphite chimney 17.  Heating is by induction coil 42 through asbestos sleeve 41 and zirconia thermal insulation 45.  Heating may alternatively be by resistance.  The crystals grow on the inside of sleeves 31-35 due to the heat gradient dropping from sleeve to sleeve towards the centre of the furnace produced by the heat sinks.  The heat sinks are constituted by the base of the container 13, the chimney 17, and the evaporating silicon 25.  The gas atmosphere may be CO, A, He, or H2 and may include as doping constituents PCl3, PH3, AsCl3, SbCl3, BCl3, or AlCl3.  A "p"-"n" junction may be formed in the crystals by using different doping agents at different periods of the preparation. In an alternative apparatus (Fig. 3 not shown) the container is provided with a central pipe with axial and radial bores to introduce the gaseous atmosphere into the base of the container, and the graphite crucible is supported on graphite sleeves, and graphite plates rest on the crucible and against the container wall.

Title: Plunger pump
Inventor: TAO RIYUUJI
IPC: F04B9/04
Filed: 1980-01-07
Abstract: PURPOSE: To obtain a stabilized discharge by a method wherein a rotation frequency of discharged liquid fluctuated when a direction in which the plunger moves is modified returns to a set flow-rate.  
     CONSTITUTION: a buffering liquid sucked from a buffering liquid tank 17 to the plunger pump 18 is detected by a pressure detector 19 for the pressure at discharging. An output signal of the pressure detector 19 is fed as an input to a micro-computer and processed, and a number of the rotations of the pulse motor 51 is controlled through a controlling device 21 to make the amount of the discharged liquid of the plunger pump 18 constant. At a time point when the plungers 5a, 5b on the discharging side are changed over, the discharge decreases and at the same time a revolving speed of a cam 10 is increased and pulses of the discharge are arrested to obtain the stabilized amount of the discharged liquid.

Abstract: It is well known that the coupling brackets 6 on jib arms 4 of a front loader can be adapted to automatically enter into locking engagement with corresponding locking fittings 12 on the tractor, an inclined plane system being established against the brackets as the tractor advances, the brackets thereby being raised to an interim position, from which they finally drop down to a safe locking connection with fittings. Release from this position is accomplished by acting on the jib arms to raise the brackets by means of hydraulic equipment of the front loader. With the invention an easier and more suitable release is achieved in that a manually swivelling cam disc 24 is fitted to the brackets 6, which interacts with the fittings 12 in such a way that, by swivelling the cam discs the brackets are forcibly lifted out of engagement with the fittings 12, following which the tractor can be reversed free of the implement without having had to make use of the hydraulics. <IMAGE>

Abstract: 1,061,828. Hydraulic brakes. KELSEYHAYES CO. Nov. 15, 1965 [Nov. 27. 1964], No. 48446/65. Heading F2F. In a pressure proportioning device adapted to be interposed between the master cylinder 10 and the rear wheel brake cylinders 28 of the hydraulic system of a vehicle, a housing 20 comprises first (46) and second (56) pistons adapted to move concurrently to displace fluid to the rear wheel brake cylinders, the first piston 46 being arranged for actuation by fluid pressure from the master cylinder 10 via connection 18 and inlet opening 22, variable force transmitting means in the form of a multiplicity of levers 68 connected between the first and second pistons to move the second piston 56 in a direction displacing fluid to the rear wheel brake cylinders 28 in response to movement of the first piston 46, the variable force transmitting means being automatically variable to change the mechanical advantage when the first piston continues to move under the influence of increasing master cylinder pressure. A by-pass means 84, 94 is provided to supply fluid directly via passageway 110, the space between a valve member 94 and a bore 84 in the by-pass device and via open valve 98 into passageway 112 to the outlet connection 24 of the pressure proportioning device and via connection 26 to the rear wheel brake cylinders to provide direct fluid communication from the master cylinder 10 to the rear wheel brake cylinders during the predetermined initial brake application. After the initial brake application the by-pass connection closes and the first piston 46 of the pressure proportioning device is exposed to the master cylinder pressure and moves to the right which results in the integral flange 50 moving also to the right in the bore 34 to actuate the levers 68 allowing them to fulcrum against a convex surface 72 of a pivot block 64 which bears against an inner face of a flange 40 forming the end member of the pressure proportioning device 20. The movement of the inner ends of the lever 68 moves a piston rod 60 to the left; thus, fluid from master cylinder 10 acting only on piston 46 produces movement of both pistons 46 and 56. The arrangement is such that a gradual lowering of the ratio of rear wheel brake pressure to the front wheel brake pressure occurs as the master cylinder pressure is increased since as the fulcrum point of the levers 68 with the curved pivot block 64 moves radially outwardly, an increased movement of the piston 56 for a given movement of the piston 46 will result and a decreased mechanical advantage is achieved due to the fact that a greater force acting against the outer ends of the lever 68 is required to deliver a given force to the piston 56 for use in pressurizing the fluid in the bores 34 and 38.
