Experimental results are presented on the effect of coupling on synchronization of two coupled nonidentical Chua’s oscillators. Two oscillators are coupled in unidirectional drive response mode. The driver is always kept in chaotic ~single scroll, double scroll! state while the response oscillator is kept in various dynamical states as point attractor, single scroll periodic, chaotic and double...

This paper describes the efficiency improvement technology of the 3D scroll compressors and the development of 3D scroll compressor for commercial air-conditioner. 3D scroll, our newly developed profile, can compress refrigerant not only radially but also axially. Therefore, higher compression ratio, higher reliability and larger capacity are obtained by introducing 3D scroll. Since the 3D scro...

This paper introduces a way of reducing the torque variation in scroll compressors. In a scroll compressor where radial compliance device such as the slider bush is used for the flank sealing, the orbiting scroll member is given the freedom of movement in the radial direction. When such an orbiting scroll member orbits around the nonorbiting scroll member whose center is offset from that of the...

Visually impaired observers read dynamically displayed text faster than text displayed in a normal page view. The goal of this study was to compare reading rates from two dynamic-presentation methods that have been proposed to facilitate reading from computer-based displays. Prior research has shown that both normally sighted and low-vision observers read text displayed to the same location, on...

My primary research interest is social behavior for software agents to achieve cooperation in general-sum normal form games. An agent can easily be programmed to constantly cooperate in a normal form game, but such an agent is not suitable for environments with potentially hostile opponents. For a rational agent, the main reason to cooperate is to induce reciprocation therefore it is necessary ...

Conceptual design of scroll expander and scroll compressor for 10 kW-class Stirling engine utilizing solar energy as heat source has been carried out. CO2 was chosen as the working fluid, since it is nontoxic, inflammable and it has relatively higher density among probably usable gases. Gas temperature at the expander inlet was set at 700 C, and that at the compressor inlet was at 40°C. System ...

Mitsuhiro Nishida Chief Engineer Fukuoka Works Mitsubishi Electric Fukuoka, JAPAN Scroll co1pressors are beco•ins popular in air conditionior and refrigeration. This is priurily due to their higher efficiency and Jo, noise/vibration characteristics. The scroll principle can be appi ied also to the stea• expander and the Brayton cycle engine, as shown in the past literature. The Otto cycle spark...
