“TADA!” is not the trumpet fanfare but the transannular Diels–Alder reaction concluding the synthesis of the tetracyclic core of the mangicols, a family of marine sesterterpenes. Further highlights in the synthesis include a novel chlorination and an intramolecular Nozaki–Hiyama–Kishi coupling reaction. Bn=benzyl.

Study on Energy Diffusive Phenomenon in Quantum Spin Chains

Journal of the Physical Society of Japan (2003)

Keiji Saito

Energy transport in quantum spin chains is considered. We first discuss the Heisenberg chain with weak perturbation. In the region where the field theoretical treatment is valid, an anomalous transport still exists in the presence of the Umklapp term. We next consider the large perturbation where trivial symmetries does not exist. In this case, the Green–Kubo formula converges, and the normal thermal conduction appears.

A microprocessor-controlled speed regulator with instantaneous speed estimation for motor drives

IEEE Transactions on Industrial Electronics (1988)

Keiji Saito K. Kamiyama Tsutomu Ohmae T. Matsuda

A method for estimating instantaneous speed, suited for a microprocessor-based speed regulator for motor drives, and the characteristics of the speed control system are described. Features of the proposed method include the estimation of instantaneous speed at a real-time point using values of average speed detected by counting for a certain time the output pulses of an encoder as well as the estimated value as the speed feedback signal for the speed regulator. Since this method allows compensation to be made for the lag time of the feedback signal caused by detection of the mean value, it contributes to improved stability of the speed regulator. In particular, this provides a significant suppression of the vibrations that are generated in motor-driven machinery.< >
