Title: Water disposal
Inventor: ICHIKI KAZUYUKI
IPC: C02F1/42
Filed: 1980-06-27
Abstract: PURPOSE:To check the deterioration of a resin and to dispose water under a stable condition, by passing the water to be treated through a mixed bed containing an excessive amount of a cation exchange resin, and then through an anion exchange resin layer containing a discoloration indicator. CONSTITUTION:Water to be treated is passed through a mixed bed in which the exchange volume of a cation exchange resin is mush bigger than that of an anion exchange resin, and then through an anion exchange resin-packed layer containing a discoloration indicator, e.g. Thymol Blue, Thymol phthalein or the like. If the exchange volume of the resin exceeds an allowable value, the indicator changes it color. As a result, the flow of the water to be treated is stopped, and the ion exchange resin is replaced by a new one. Consequently, water disposl can be done contantly under a stable condition.

Abstract: PROBLEM TO BE SOLVED: To enhance reliability in a grown silicon oxide by a method, wherein radio frequency power generates plasma containing oxygen atoms and radicals with a mixing gas of a rare gas and an oxidizing gas containing a nitrogen dioxide, and is annexed to form an oxide film with silicon at specified temperatures. SOLUTION: A rare gas and oxygen are introduced in various ratios in a CVD chamber, into which a silicon substrate to be oxidized, is entered. The ratio of oxygen in the mixing gas is changed from 1 to 15%, and also gas pressures are changed to 100 to 4,000 mTorr. A RF power is changed to 100 to 1,500 W with respect to a total area of 1,000 cm2, and the temperatures are changed to 100 to 400 deg.C. A typical C-V curve of an oxide film grown on silicon is substantially ideal, and does not have hysteresis. A compound containing fluorine, for example, HF, NF3, are added to a mixing gas, so that oxygen radicals are generate at low temperatures in order to form an oxide film, thereby further enhancing oxidizing characteristics. Furthermore, after a SiO2 film is grown, annealing process such as gas annealing process, or the like can be conducted in order to further improve a breakdown strength characteristic of a film.

Abstract: PURPOSE:To easily insert terminals into contacts without damaging packages of the electronic parts and bending the terminals at the time of the insertion even in case of a number of terminals by setting up the respective tapered tips of the terminals in a plurality of shapes. CONSTITUTION:When the tapered tips of the terminals 2a, 2b, 2c provided on an IC body 1 are made different in shape and a taper La of the terminal 2a on the center side is made so small as to be almost a straight line Sa, insertion resistance at the time of inserting it into a contact 5b increases.

The taper Lc of the terminal 2c is further larger than the taper Lb of the terminal 2b so as to almost nullify insertion resistance up to reaching a linear part Sc. Accordingly, at the time of inserting terminals into the contacts 5, the terminal 2a on the center side having large insertion resistance is firstly inserted so that the other terminals 2b and 2c can be easily inserted.
