A coding apparatus includes a predicting unit, an intermediate-code generating unit, a first coding unit and a second coding unit. The predicting unit generates a piece of prediction data based on each piece of pixel data constituting a color image. The intermediate-code generating unit compares each piece of prediction data with the corresponding piece of pixel data, to generate an intermediate code in accordance with whether or not a difference between each piece of prediction data and the corresponding piece of pixel data is in a predetermined range. The first coding unit performs entropy coding on the generated intermediate code. The second coding unit performs entropy coding on the generated intermediate code. The intermediate-code generating unit assigns each generated intermediate code to either of the first and second coding units according to whether or not the difference is in the predetermined range.

A center core laminated part and a side core laminated part are formed separately from each other. The center core laminated part is integrated with the side core laminated part by engaging depressed engaging portions with projected engaging portions, wherein the depressed engaging portions and the projected engaging portions are formed relatively on the corresponding opposite surfaces, to form a laminated core part for forming a magnetic path.

An electrical power system protection device includes a circuit breaker and a switch connected in series to a power line. The protection device also has a current limiting element connected in parallel to the circuit breaker. When the level of electrical current flowing in the power line, detected by a current detector, has exceeded a predetermined first set level, a first over-current detector delivers immediately a trip command to the circuit breaker. As a consequence, fault current is commutated to the current limiting element so that any drop of voltage in the power line upstream of the circuit breaker is greatly suppressed. When a state in which a predetermined second set level is exceeded by the detected current level is continued beyond a predetermined period, a second over-current detector delivers an off command to the switch, thus protecting the upstream portion of the power line against the fault in this power line. The current level is set to fall within a range which activates a momentary element of an over-current relay of a receiving end breaker of a downstream sub-system connected to the power line. In the event of a failure in the downstream power line, the receiving end breaker is tripped immediately so that the sound portion of the power line is reset to a normal state of operation.

A process and apparatus for correcting a crude magnetic field of a main field generator having correcting magnetic field generators associated therewith to produce a substantially homogeneous corrected field. The process comprises the steps of measuring the distribution of said crude magnetic field at a plurality of points, expressing the crude magnetic field at each of the plurality of different measured points by a polynomial equation which contains a main homogeneous magnetic field component, successively higher order inhomogeneous magnetic field components, and a residual, determining the magnetic field output for the correcting generators such that the successively higher order inhomogeneous magnetic field components of the crude magnetic field are completely cancelled by the magnetic field outputs, respectively, of the correcting generators, and producing and superpositioning on the crude magnetic field the determined magnetic field output from the correcting generators.

A method for forming a micropattern, comprises the steps of forming an organic polymeric material layer on a substrate, forming a silicone layer on the organic polymeric material layer, selectively irradiating a surface of the silicone layer with a high-energy beam, exposing the surface of the silicone layer to a radical addition polymerizable monomer gas so as to form a graft polymer film on an irradiated portion of the surface of the silicone layer, performing reactive ion etching using the graft polymer film as a mask so as to form a silicone pattern, and performing reactive ion etching using the silicone pattern as a mask so as to form an organic polymeric material pattern. The method allows formation of a resist pattern with a high precision and a high aspect ratio.

Resin pooling grooves are disposed so as to extend over entire regions in a thickness direction of a first magnet holder on two sides of a bottom surface in a width direction of a first receiving groove, and resin pooling grooves are also disposed so as to extend over entire regions in the thickness direction of the first magnet holder on two side surfaces of the first receiving groove near the bottom surface. A first resin injection aperture is disposed through the first magnet holder so as to communicate with the resin pooling grooves over an entire region in the thickness direction. A first permanent magnet is held by the first magnet holder by fitting the first permanent magnet into the first receiving groove together with a first magnet cover, and injecting a resin material into the resin pooling grooves through the first resin injection aperture and hardening it.
