A ferroelectric capacitor including a bottom electrode which has a projecting portion, a top electrode, a ferroelectric layer and a dielectric layer formed between the bottom electrode and the top electrode. The dielectric layer is formed on a peripheral area of the bottom electrode. The ferroelectric layer is formed on the dielectric layer and on the projecting portion of the bottom electrode. As a result, a damaged layer which is formed during an etching process occurs at the ineffective area of the ferroelectric capacitor.

An encoder includes an encoded-bit-string generating unit that generates a plurality of bit strings encoded by scrambling with respect to an input bit string; a DC-component evaluating unit that selects a bit string having a predetermined width in the bit strings generated by the encoded-bit-string generating unit, while shifting bits one by one or every m-bits, where m is a positive integer, and evaluates the DC component in each of the bit strings selected; and a bit-string extracting unit that extracts a bit string with suppressed DC component from among the bit strings encoded, based on a result of an evaluation by the direct-current-component evaluating unit.

A method of refilling an ink bag of an ink cartridge for use in an ink-jet recorder. The method includes first removing the ink cartridge and ink bag from the ink-jet recorder. The ink bag may then be refilled by positioning the ink bag on a surface, inserting an ink needle into a port of the ink bag, and by discharging ink from the ink bag and charging the ink bag with a specified quantity of ink.

The invention provides a process for the preparation of a thermoplastic elastomeric resin composition comprising (a) 100 parts by weight of a block copolymer consisting of at least two polymeric blocks (A) composed of a vinyl aromatic compound and at least one polymeric block (B) composed of a conjugated diene compound, or a hydrogenated block copolymer, (b) 20 to 300 parts by weight of a non-aromatic softening agent for rubber, (c) 1 to 100 parts by weight of a peroxide-crosslinking type olefinic resin or a copolymeric rubber containing said resin, and (d) 10 to 150 parts by weight of a peroxide-decomposition type olefinic resin or a copolymer containing said resin, characterized in that the process comprises a step of heat-processing component (a), component (b), at least a part of component (c) and a part of component (d) in the presence of an organic peroxide to cause crosslinking, and a subsequent step of blending these with the remaining part of component (d) and, if any, the remaining part of component (c). The obtained composition is soft and good in rubber properties, mechanical strength and processability, and is less sticky.

An optical disc having a track pitch of 0.85 .mu.m, a shortest pit length of 0.49 .mu.m, a pit depth of 100 nm, and a pit width of 0.35 .mu.m is rotate at a linear velocity of 2.4-2.8 m/s such that the same is optically reproduced by a laser beam having a wavelength of 635 nm which is converged to a spot size of 0.9 .mu.m by an objective lens having a numerical aperture of 0.6. Accordingly, data is read from the optical disc at a transfer rate of 5.6 Mbps.

A two-cycle internal combustion engine comprises a cylinder head having an intake port and two exhaust ports opened to a combustion chamber, to which compressed fresh air is introduced via an intake valve. The intake valve and two exhaust valves are operated in response to a crank angle. One of the exhaust valves is opened earlier than the other exhaust valve and the intake valve when the speed of the downward movement of the piston is relatively high, such that a part of exhaust gas in the one exhaust port flows back to the combustion chamber in that condition. An exhaust gas swirl rotating around a cylinder axis is formed when the exhaust gas flows back and the fresh air is slowly introduced onto the exhaust gas swirl in that condition.

A water producing-air conditioning system comprises a water producing apparatus which adsorbs moisture in the ambient air on an adsorbent or absorbent and evaporates water adsorbed on the adsorbent or absorbent by heating it and condenses steam to obtain water;a heat-exchanger which heat-exchange the ambient air with a hot dry air discharged from said water producing apparatus during adsorbing moisture on the adsorbent or absorbent; andan evaporation-cooling apparatus for forming a cold wet air by evaporating water and cooling it by contacting water with a dry air at the ambient temperature passed through said heat-exchanger.The hot air heated by said heat-exchanger or the cold air obtained from said evaporation-cooling apparatus is utilized for the air conditioning. The system can be used for comfortable living in a severe condition such as a desert by the effective combination of the evaporation-cooling apparatus with the water producing apparatus under utilizing heat-exchange in high efficiency.

A water producing apparatus is, as a principle, to produce liquid water from moisture in the air by adsorbing the moisture on an adsorbent and then desorbing water from the adsorbent by heating it and condensing steam into liquid water. The water producing apparatus comprises a recycling passage for recycling steam through an adsorbent column in the desorbing step, a heater for heating the steam in the recycling passage; and a condenser branched from the recycling passage. In the desorbing step, steam in the recycling passage is heated by the heater to heat the adsorbent and to desorb water from the adsorbent and excess of steam corresponding to the desorbed steam is passed from the recycling passage to the branched condenser and is condensed to obtain liquid water in high efficiency.

An impeller includes a hub plate and a plurality of blades circumferentially disposed at intervals on one surface side of the hub plate. Each blade has a shape formed by piling up a plurality of blade sections in a blade height-wise direction of each blade in a reference impeller in which the hub plate intersects with the blades and which includes a linear element blade in the blade height-wise direction so as to form a curvilinear element blade. In piling up the blade sections, amounts of tangential lean and sweep to be applied to the blade sections are increased as it goes from an end face of at least one of a hub plate side end and a counter hub plate side end toward a span intermediate part of the blade.

There is provided a data collecting device configured to collect data from a plurality of nodes. An inquiry transmitting unit transmits inquiry messages to request transmission of the data to the nodes, respectively. A response receiving unit receives response messages including the data from the nodes, respectively. A reception scheduler generates a reception schedule of the response messages from the nodes based on request information indicating data collection condition from the nodes. A transmission scheduler generates a transmission schedule of the inquiry messages based on the reception schedule and characteristics of communication with the nodes. The inquiry transmitting unit transmits the inquiry messages to the nodes, respectively, based on the transmission schedule.
