Abstract: PURPOSE:To realize a high selecting-ratio process by using specified materials as insulating material for parts where insulation is required in a reaction chamber and a plasma generating chamber and as sealing material for maintaining a vacuum state. CONSTITUTION:An upper electrode sealing part 14, a lower electrode sealing part 17, a sealing part 15 for upper and lower chambers and a lower electrode cover 16 are formed by using silicon macromolecular material having rubber property.

When etching for forming a gate electrode (Poly-Si) is performed with fluorine-based plasma, a non-carbon-based TEOS film is used as a mask for etching. Then the carbon which is dissociated by the plasma is further decreased. The selecting ratio between the gate electrode material (Poly-Si) and a silicon oxide film (SiO2) as the ground for the electrode material is not increased. The selecting ratio for the gate electrode (Poly-Si) and the ground oxide film (SiO2) is further improved.

Title: System for dynamic load distribution of multi-processor
Inventor: OKADA MIKIO
IPC: G06F15/173
Filed: 1988-02-16
Abstract: PURPOSE:To avoid competition between data and load information and to attain a load distribution and an exclusive control by further combining a network combined into a ring shape to communicate the load information into the ring shape and forming. CONSTITUTION:Plural processing processors 2 are combined by a ring network 1 and the plural networks 1 are combined with a ring network 3 through a load distribution processor 4. The entire load information of the processor 2 flows in the network 1 as one of packets. When the processor 2 is necessary to request the processing to others, the packet is referred and it is requested to the empty processor 2. When no empty processor 2 exists, the processor 4 flows the packet to the network 1 having the empty processor 2. Thus, the competition between the data and the load information is avoided and the load distribution and the exclusive control are attained.

Abstract: In an annular saw, that is to say a circular saw with an annular saw blade, the saw blade is adapted to rotate about an imaginary centre axis by being driven via a drive shaft which is parallel to the centre axis and has a fulcrum between the annular saw blade and its centre. Mounted on the drive shaft (27) are two drive rollers (25, 26), of which the adjacent surfaces (41, 42) are bevelled at a certain bevel angle so that the rollers comprise drive surfaces which,. between them, form a wedge-shaped groove (40). The two lateral surfaces of the saw blade (8) are bevelled in a corresponding manner within a region (13) close to the inner edge (<sub>15</sub>) of the saw blade, the bevel angle being the same as for the drive rollers, the bevelled edge portion of the annular saw blade being clamped between the bevelled drive surfaces of the drive rollers in the wedge-shaped groove. The invention also relates to the annular saw blade, the inner edge portion (13) of which is symmetrically bevelled to comprise encircling bevel surfaces (14).

IPC: G09G5/28
Filed: 1990-02-14
Abstract: PURPOSE:To generate characters of high quality by converting contour data on a font into dot data by an outline converting means and correcting projections of dots which are generated at peak parts of a curve smoothly by a curve correcting means with curve correction data. CONSTITUTION:Shape data on the outline font(OF) is read out of the character ROM 14 of an OF storage part. Data indicating a position where a curve correction is to be made is read out of a curve correction data memory 24. The curve function of the read outline data is developed to generate many interpolation points in one segment. Those interpolation points and the start and end points of a straight line are connected in order with linear vectors to obtain short vector data. The short vector data are converted into dot data. When the curve is corrected with the curve correction data and only one dot projects, the unattractive part of the projection is corrected. Namely, dots are added above and below or on the right and left sides of a specified point.
