Carbon atoms are arranged stably in the form of a torus or in the form of a helical coil to give novel topological properties to the carbon atoms to thereby provide various functions of carbon molecules. A plurality of sixfold rings each including six carbon atoms are arranged in the form of a torus, and then these sixfold rings are partially replaced by fivefold and sevenfold rings to obtain a stable structure. That is, a part of the outer wall surface of a torus constituted by a plurality of sixfold rings and a part of the inner wall surface of the torus are replaced by fivefold rings and sevenfold rings respectively to obtain a stable structure. Further, a molecule in which carbon atoms are arranged to form a toroidal or helically-coiled stable structure or a cluster in which a plurality of such molecules are arranged spatially is constructed by using an STM. Further, a micro part or device using the hole of the torus/helical coil and the inside of the ring thereof is formed by combining a plurality of such molecules/clusters.

A generation method of particle simulation programs includes a translation and discretization process of equation of motion of particles for recognizing attributes of a space and particles based on information of the particle simulation to generate expressions of calculations, tables, and internal data and a generation process of programs for creating calculation programs and simulation input data from the generated expressions of calculations, tables, and internal data. According to information inputted from a screen of a graphic terminal, various control conditions are produced to control processes of the simulation.

A radome includes a radome member formed of a dielectric to protect an antenna element from outside space and a structural member formed of metal for supporting the antenna element at the center thereof and to which the radome member is joined at the periphery of the antenna element to support the radome member. When the radome member is formed of dielectric and the structural member is formed of metal, the junction therebetween serves as a kind of antenna and the radiation characteristic of the ordinary antenna element is disturbed. To solve this problem, a portion of the radome member through which an electric wave is transmitted is formed of material through which an electromagnetic wave having a frequency identical with that of the electric wave is transmitted and a junction formed between the radome member and the structural member has a structure for absorbing the electric wave.

A fluid-damping vibration-isolating support device comprising a main support body having a rubber base member and a closed enclosure internally thereof; and a partition plate dividing the enclosure into two chambers which intercommunicate through an orifice and are filled with a liquid. The partition plate comprises a separator member and a stopper member. The separator member is formed of an outer peripheral thick wall portion having an orifice and an inner thin flat plate portion having at least one through-hole. The stopper member has two opposed plate sections provided so as to cover the through-hole and is captured to the separator member slightly movably to the degree that the plate sections are in contact with or separate from both faces of the flat plate portion. The stopper member serves to close upon low frequency vibration and open upon high frequency vibration, so that in the high frequency region rise of hydraulic pressure can be suppressed and dynamic spring rate can be lowered.

During the receipt of a result of comparison from the phase detector representing that the synchronization signal is phase-delayed behind the input signal, the selection circuit sequentially selects the M number of counters, one by one, in a cyclic fashion, in such a direction as to permit the reference clock input to be phase-advanced correspondingly, so that the frequency-divided output signal from the counter to the phase detector can be sequentially phase advanced by 1/M of one cycle of the reference clock. During the receipt of a result of the comparison indicating that the synchronization signal is phase-advanced ahead of the input signal, on the other hand, the selection circuit sequentially selects the M number of counters, one by one, in a cyclic fashion, in such a direction as to allow the reference clock input to be phase-delayed, so that the frequency divided output signal from the counter to the phase detector can be sequentially phase-delayed by 1/M of one cycle of the reference click. When a phase difference occurs between the input signal and the synchronization signal, one cycle time of the synchronization signal is increased or decreased by 1/M of one cycle of the reference clock, thus assuring an enhanced time resolution.

A heat exchange system for realizing an adequate heat exchange among a plural type of fluids uses a refrigerant radiator and a radiator which are combined to have one unit for enabling heat exchange between a refrigerant and a coolant, and decreases an inflow amount of the coolant flowing into the radiator when coolant temperature of the coolant flowing into the radiator is equal to or higher than a second standard temperature, which is set to be lower than a temperature of the refrigerant flowing into the refrigerant radiator, and is equal to or lower than a predetermined first standard temperature. In such manner, heat from the refrigerant is effectively transferred to an outside air by reducing an unwanted heat exchange between the refrigerant and the outside air.

When a temperature of feed air blown into a space for air conditioning cannot be increased up to the target temperature in an indoor condenser of a heat pump cycle included in a gas injection cycle, the volume of the feed air flowing into the indoor condenser is decreased. Thus, the temperature of the refrigerant condensed by the indoor condenser is increased, while the amount of a compression work in a high-pressure side compression stage of the compressor is increased, which suppresses the lack of the heating capacity of the feed air blown into the space for air conditioning.
摘要:
A heat pump cycle is capable of switching an operation mode to a cooling operation mode, a heating operation mode and a dehumidifying-heating operation mode, and is applicable to an air conditioning device. The heat pump cycle is configured to set both of a high-pressure side pressure reducing device and a low-pressure side pressure reducing device—in a throttled state and a fully open state. In this way, the heat pump cycle realizes cooling, heating, and dehumidifying-heating by a simple structure without providing separate refrigerant flow passages extended from a compressor to an outside heat exchanger based on the operation modes of the air conditioning device.

A solar cell includes a p-n junction formed by joining a p-type semiconductor and an n-type semiconductor. The p-type semiconductor is a chalcopyrite compound semiconductor with a band gap of 1.5 eV or more within which an intermediate level exists with a half bandwidth of 0.05 eV or more. The intermediate level is different from an impurity level. The chalcopyrite compound semiconductor includes a first element having first electronegativity of 1.9 or more in Pauling units, the first element occupying a lattice site of the semiconductor. A portion of the first element is substituted with a second element having second electronegativity different from the first electronegativity, the second element being a congeneric element of the first element. The intermediate level is created by substituting the first element with the second element.
