Effects of ketamine on the sodium (INa) and L-type calcium currents (ICa) were examined by using whole-cell patch clamp techniques in guinea pig single ventricular myocytes. The mode of action of ketamine was compared with those of quinidine, a sodium channel blocker, and verapamil, a calcium channel blocker. Ketamine (30-300 microM) inhibited both INa and(More)
Broadcast-based information dissemination systems on the Internet are becoming increasingly popular due to advances in the area of Web technology and information delivery. In this paper, we propose a concept and a way to construct a virtual TV channel, which is a user-deened (virtual) channel from existing push-based Internet channels. Our virtual TV(More)
A number of haptic devices have recently become available on the commercial market, and these devices are becoming common not only in research but in consumer use as well. In this paper, a new parallel mechanism, referred to herein as DELTA-R (meaning DELTA-Redundant, formerly referred to as DELTA-4) is proposed for a new haptic device having high-quality(More)
This 600MHz single-chip multiprocessor consists of two M32R 32b CPU cores[1] and 512kB shared SRAM, and is designed for embedded microcontroller and system on chip (SoC) core. Since software for an embedded systems increases its complexity, embedded processors [2]-[4] are required to increase performance. At the same time, low power dissipation is still a(More)
Silicon carbide (SiC) has a range of useful physical, mechanical and electronic properties that make it a promising material for next-generation electronic devices. Careful consideration of the thermal conditions in which SiC [0001] is grown has resulted in improvements in crystal diameter and quality: the quantity of macroscopic defects such as hollow core(More)
