摘要:
An optical amplification medium doped with Er3+ ions is selected from the group of a fluoride glass, a chalcogenide glass, a telluride glass, a halide crystal, and a lead oxide based glass. The Er3+ ions are excited by light of at least one wavelength in the range of 0.96 &mgr;m to 0.98 &mgr;m. A laser or an optical amplifier includes this optical amplification medium doped with Er3+ ions. Furthermore, an optical amplification method performs an optical amplification using the optical amplifier having the optical amplification medium doped with Er3+ ions. Thus, the laser to be applied in the field of optical communication, the optical amplifier having the characteristics of low noise and high gain, and the optical amplification method can be provided.

摘要:
Image forming method is disclosed using a light-sensitive material which comprises a support and a light-sensitive layer provided thereon. The light-sensitive layer contains silver halide, a reducing agent and an ethylenically unsaturated polymerizable compound. The light-sensitive material of the present invention further contains a polymerization inhibitor releasing (PIR) compound. The polymerization inhibitor releasing compound has a function of releasing a polymerization inhibitor when the compound is heated or reacted with a base. The silver halide, the reducing agent, the polymerizable compound and the polymerization inhibitor releasing compound are preferably contained in microcapsules which are dispersed in the light-sensitive layer.

The silver halide light-sensitive material has a small fluctuation in sensitivity even when the processing temperature changes and has an improved color reproduction and an excellent discrimination and can achieve low Dmin and high Dmax.
摘要:
A digital signal processing circuit for processing and recording data at various selectable rates, having an input/output circuit for receiving and outputting a digital signal; a recording circuit for generating a recording signal based on a digital signal received by the data signal processing circuit; a playback circuit for retrieving recorded data; and a demodulation circuit for demodulating retrieved data. The processing and recording rates are determined by control data supplied to the circuit either via an operator or from a recorded signal.
摘要:
A recording and/or reproducing apparatus divides long bit-length data into upper bit data and lower bit data, and records both data along with discriminating data in a manner that the upper-bit data and the lower-bit data are allocated and recorded, on an alternating basis, onto the scan start side areas and the scan end side areas of a plurality of pairs of recording tracks, in order to obtain more high-quality digital audio signal to be recorded and reproduced.
摘要:
PTC (positive temperature coefficient) thermistors of a novel configuration and a method for their manufacture. The PTC thermistors have a PTC element sandwiched between two electrodes for which leads are formed as an extension of each of the two electrodes protruding beyond the edge of the PTC element. Several manufacturing methods avoid undue thermal and physical stress to the PTC composition while providing PTC thermistors having a variety of shapes and configurations.
