Title: Cutting insert and its manufacture
IPC: B23C5/02
Filed: 1993-02-04
Abstract: PURPOSE: To manufacture a cutting insert having highly accurate as-used dimensions with an easy operation by making a blank insert-sintered body having a top chip surface, a bottom surface and an edge surface linking both the surfaces and grinding the edge surface. CONSTITUTION: Hard metal powder is used as a raw material, and the blank insert for the cutting insert 1 having the top chip surface 2, the bottom surface 3 and one or more edge surfaces 4A to 4D linking both the surfaces is formed by press molding of the metal powder. In such a case, the edge surfaces 4A to 4D are divided into parted surfaces which are previously formed of recessed parts 15 at the bottom, and includes relief surface portions 8, which intersect the top surface 2 at an acute angle, to form therewith a cutting edge 6 to reduce the area of a part to be ground. After this press-formed body of powder is sintered, only a lower portion of the edge surface disposed below the relief surface portion 8 is ground.  Each bottom of the edge surfaces 4A to 4D is ground so that the dimensions between the bottom and the cutting edge 6 located oppositely in the diameter direction is within a tolerance of 1.0 to 20 μm, thereby improving the dimensional accuracy of the cutting insert.

Filed: 1986-01-28
Abstract: PURPOSE:To obtain a novel channel plate easy to manufacture by making sheets having plural bores, with the adoption of a paste material with secondary electron emission capability, through the thick film printing method, and stacking the sheets after aligning their bore positions in order to form them into one body under thermal treatment. CONSTITUTION:A paste material is prepared such that material such as titanate zink semiconductor ceramics composition which is able to emit secondary electrons is kneaded with vehicle, dispersant and binder. A sheet 15 having circular bores 14 arranged in a matrix shape is made by printing an agent on the sheet by using a printing pattern 13. Several sheets 15 are superposed on a support plate 17, where a separating agent 16 is applied before hand, after their bore positions are aligned, and the laminated body 18 of a sheet 15 is thereby formed. The laminated body 18 is then removed from the base 17 and fused under thermal treatment. The body 18 is further cut in a circle in the superposed direction, and electrodes 5a and 5b are thereby formed so that a channel plate is obtained.

Title: Displacement detector
Inventor: SAGIO KENICHI
IPC: G01B7/00
Filed: 1988-01-28
Abstract: PURPOSE:To obtain a displacement detector easy to assemble with a simple construction, by detecting an electrostatic capacitance between a pair of electrodes arranged on a magnet and a superconductor. CONSTITUTION:A magnet 22 is arranged between superconductors 18 and 20 within a case 12 and mounted on a mobile body 24. Electrodes 26 and 28 are arranged as opposed to each other at the center of the top of a superconductor 20 and the undersurface of the magnet 22 to form a capacitor 30. Here, when a liquid nitrogen is supplied to cooling tanks 14 and 16 of the case 12 to make the superconductors 18 and 20 superconductive, the magnet 22 is kept in the center between the superconductors 18 and 20 receiving a repulsive force by a Meissner effect from the superconductors 18 and 20. When a displacement of an object to be measured is transmitted to the magnet 22 through the mobile body 24 with this condition as zero-point of a displacement detector, a gap (d) between the electrodes 26 and 28 varies to change an electrostatic capacitance C of the capacitor 30. Thus, a gradation of an ammeter 38 is displayed as displacement of the magnet 22 thereby enabling production of a displacement detector easy to assemble with a simple construction requiring no coil or the like.

IPC: H01M8/24
Filed: 1993-01-08
Abstract: PURPOSE:To provide a solid electrolyte fuel cell type power generator furnace in which vertically positioned cell-stack can be supported inside a power reactor casing without generating large stress in the cell-stack.

Title: Manufacturing sheet of two-axis-stretched styrene resin
Inventor: WADA TADAHIKO
IPC: B29C55/12
Filed: 1979-02-19
Abstract: PURPOSE: To provide a sheet improved in blocking and lapping properties and appearance, by enbossing a styrene resin sheet and thereafter stetching the sheet.  
     CONSTITUTION: A styrene resin is molten by an extruder and extruded into a sheet shape by a T-shaped die. At least one side of the resin sheet is embossed by a tightly fitting roll having a projection and recess pattern while the temperature of the sheet is by about 20°C higher than the difference between the melting and the extrusion temperatures. The embossed sheet is extended in the directions of a horizontal and a vertical axes, thereby obtaining a two-axis-stretched styrene resin sheet. Since the surface of the sheet is provided with a projection and recess pattern, the blocking tendency of the sheet in stacking is little although it is made of styrene resin. Because silicone oil, inorganic fine grains or the like are not used, the appearance of the sheet is excellent.

Title: Burner
Inventor: ADACHI KAZUHIRO
IPC: F23D11/24
Filed: 1983-02-07
Abstract: PURPOSE:To improve the combustion capacity and to reduce the combustion noise by extending the flame over the combustion completing area depending on the direction of air injecting from a vaporizing cylinder. CONSTITUTION:Combustion air generated by a motor 6 and a fan 7 advances toward vaporizing cylinder 8 through a duct 11. In this case, combustion air is injected within the combustion chamber so that the combustion air intercrosses with the radiation rays and further the wall surface in the vicinity of an auxiliary combustion cylinder 10, due to the raised shape of the air injection hole 9 of the injection cylinder 8. On the other hand, kerosene sprayed through a nozzle 5 advances toward the vaporizing cylinder 8, is mixed with injection air to carry out combustion. At the initial stage of the combustion, the kerosene assumes a dispersive combustion. But due to the temperature rise within the combustion chamber and the temperature rise of the cylinder 8, the kerosene assumes a premixing combustion, and becomes blue flame by air from the air injection holes 9 formed at the upper part of the cylinder 8. The flow of the blue flame is the same as the flow of air injected radially. Hence, flames from respective injection holes 9 assume a state wherein the flames are filled from the cylinder 8 up to the auxiliary combustion cylinder 10. Therefore, the kerosene from the nozzle 5 is uniformly vaporized, and thus an excellent combustion is achieved. Further, since injected air does not interfere with each other, it forms a laminar flow, and hence flame is stabilized and combustion noise is also reduced.
