摘要:
A method of manufacturing solid electrolyte chip capacitors. Each capacitor comprises a substantially rectangular capacitor element having a cathode layer surrounding it, an anode conductor rod protruding therefrom and a pair of electrode terminals disposed on the bottom face thereof. A metal strip, such as the material of electrode terminals, is punched and pressed to form pairs of L-shaped terminals with horizontal legs connected to the remainder of the strip, which face toward and spaced from each other by a distance corresponding to the full length of the capacitor element, each of the vertical legs has a pair of facing side wings separated by a distance corresponding to the width of the capacitor element. The capacitor element is inserted in each enclosure defined by the vertical legs and their wings and positioned precisely, and then encapsulated with synthetic resin. The resultant products are cut off from the strip.

Because a sample holder 100 is composed of a plurality of convex parts 1 provided on a top face of a base substance 2, and the plurality of convex parts 1 are spherical surfaces 1a formed of a single crystal or amorphous material, frictional wear of the sample at contact parts between a sample 4 and the convex parts 1 is reduced, thereby making it possible to inhibit particle generation. Further, because a joining layer 3 is formed of a single crystal or amorphous material, there is no defect that particles scattered on the sample holder 100 fill up it, which makes it possible to easily keep it in a clean state by cleaning, and it is possible to effectively reduce reattachment of particles to the sample 4.

An aluminous sintered product comprising 70 to 96% by weight of an alumina component and 4 to 30% by weight of additives, said additives including at least the one selected from oxides of elements of the Group 5a of periodic table and at least the one selected from oxides of metals of the iron family and oxides of manganese, titanium, calcium, magnesium, chromium and silica, and said aluminous sintered product exhibiting a volume resistivity of from 1.times.10.sup.7 to 1.times.10.sup.13 .OMEGA.-cm over a temperature range of from 25.degree. to 75.degree. C. and an absolute value of the temperature coefficient of volume resistivity of not larger than 1.8%/.degree.C. under the application of high voltages. The sintered product is used as antistatic part such as conveyer arm, handling jig, tweezers for holding wafers and the like that must not be electrostatically charged in an apparatus for producing semiconductors, and as resistance substrate, electrically conducting material, contact, heater, part in vacuum tubes, and part for electron guns in a CRT such as of TVs and the like.
