Title: Method of fabricating ceramic substrate
Inventor: SAWAI HIDEO
IPC: H05K1/16
Filed: 1979-01-18
Abstract: PURPOSE:To provide a method of fabricating ceramic substrate, which method is adapted for mass production and enlargement, and can lower the fabrication cost by electrolessly plating all resistors and wires on the ceramic substrate. CONSTITUTION:A resistor 6 is formed by an electroless plating using Ni-B, Ni-P on a ceramic board 1 itself. At this time the pH of the bath is restricted to control the specific resistance value of the film. When forming a printed circuit board 7, it is electrolessly plated using Cu, Au, etc. When the board is laminated with multilayers using this, insulating layers 8 are interposed among the layers. Thus, the substrate can be readily fabricated, and this method is adapted for the formation of a microminiature circuit.

Abstract: PROBLEM TO BE SOLVED: To enhance a flowing down ability of drainage and prevent flowing out to the drain pipe at each floor by forming a vertical drain pipe between aggregation couplings at each floor with a ribbed pipe having a plurality of spiral ribs in its inner peripheral surface and a pipe with a smooth inner surface. SOLUTION: A drain pipe 22a at each floor is connected to a vertical pipe passage 12 via an aggregation coupling 20. The vertical pipe passage 12 is formed of a vertical drain pipe 18b composed of a smooth inner surface pipe 26 connected by a socket pipe 28 to an inner surface ribbed polyvinyl chloride pipe 24 with a plurality of spiral ribs 24b formed in its inner peripheral surface.

When it enters in the pipe 26 from the inner surface ribbed pipe 24, circulation is attenuated to be a water flow in substantially parallel to the pipe shaft so that drainage does not flow out to the drain pipe 22a at each floor and flows down in the aggregation coupling 20. Moreover, drainage is precluded from overflowing in the inside of each room caused by a cleaning material stayed in the drain pipe 22a.

IPC: H01J29/60
Filed: 1984-01-17
Abstract: PURPOSE:To effectively avoid generation of a false signal due to a returning beam by providing a reflecting electrode with a surface of revolution opposite to a target. CONSTITUTION:A position R2 and an angle theta at which a returning beam 10 in an MS type pickup tube reaches to a deflecting electrode plate 8 are proportional to the deflection volume R1 of a primary electron beam. Namely R2proportional R1, thetaproportional R1, and the returning beam 10 is seen to return from a point P on the axis in phantom. The reflecting electrode 8 has a curved surface of revolution and especially, when the curved surface is a hyperbolic tangent tanh surface, the returning beam 10 is once reflected in point symmetry with respect to a reflection point and a tube axis, and it is again reflected to become a reflecting beam 11 at the place. If there is no electric field and no magnetic field, the reflecting beam 11 is focused on an emitting point P of the returning beam 10, however, in practice, it is possible for the beam to reach within a scanning region A by the action of an electric field to deflection and a magnetic field of convergence, and to prevent generation of an image due to the returning beam.
