Effects of a treatment of grape peels with pulsed discharges under water at applied voltage from 30 to 60 kV on the evolution of total polyphenols in Kyoho grape processing was investigated using a six-stage Blumlein-line pulsed power generator. The grape peels were sunk in diluted water and the pulse voltage was applied to five needle electrodes set into the water. The experimental results showed...
We have developed 12-channel × 20-Gbps optical transmitter/receiver modules with 9 × 14-mm footprints. To achieve stable optical coupling efficiency, we also developed a precise multi-chip mounting technique. The three dies of 4-channel vertical-cavity surface-emitting laser (VCSEL)/photodiode (PD) arrays are mounted at the same time. The accuracy of the Z-axis can be controlled by monitoring the...
We describe here two infertile male patients who were referred to our hospital with azoospermia at the ages of 33 and 30 years, respectively. Hormonal examinations led to a diagnosis of congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency in both patients. Genotyping revealed that the patients had a homozygous I172N and a heterozygous compound I172N/IVS2-13A/C>G mutation, respectively...
New dispersion-flattened fibers having negative dispersion of about -8 ps/nm/km over whole telecommunication band are developed. Transmissions with 10 Gb/s directly modulated LDs over 51 km at 1275 nm and over 80 km at 1550 nm are realized without dispersion compensation.
The mid-stage VASC scheme has successfully maintained the gain-profile of the TDFA within 0.2 dB under the operational conditions where the channel number is from 4 to 32 and the dynamic range is 8 dBp-p
8-channel Variable Optical Attenuator has been fabricated using PLC technology. Electric consumption power for 10dB attenuation control was reduced to less than 100mW/channel with average insertion loss of 1.59dB.
