Title: Semiconductor optical amplifier
Inventor: IMOTO KATSUYUKI
IPC: H04B10/2507
Filed: 1999-01-20
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor optical amplifier which has low noise, a high gain and wideband characteristics. SOLUTION: In this semiconductor optical amplifier, light having a wavelength band of a loss region as a monitoring light is inputted to the semiconductor optical amplifier together with signal light, so that a wavelength region having the gain of the signal light selected in a gain region can be enlarged, its gain can be also increased, and noise characteristic can be improved. A high gain and low noise can be attained with a small signal light power. By monitoring the monitor light inputted to the amplifier at an output side, it can always be monitored whether the amplifier normally operates. Part of the power of the signal light amplified at the output side of the amplifier is extracted and converted by a photoelectric converter circuit 10-1 into an electrical signal.  A controller 11 for a drive circuit of a monitor light source is operated by the electrical signal, to thereby adjust the power of the monitor light and keep the amplified signal light power always constant.

IPC: H03K3/027
Filed: 1986-01-22
Abstract: PURPOSE:To constitute Schmitt trigger circuit with ease of circuit design and capable of high speed operation by using a bipolar transistor (TR) whose emitter connected to the 1st input of the logic gate is connected to the 2nd input of the logic gate. CONSTITUTION:When a potential at an input terminal rises, exceeds a threshold voltage VTH up to VTH+VF, a P-channel MOS TR 4 whose gate is connected to the output of a two input NAND gate 3 is turned on, and since the 2nd input is fixed to a power supply, the potential at a node A rises and the potential at the input terminal rises at the same time. When the potential at the input terminal descends lower than the threshold voltage VTH, the output of the two input NAND gate 3 is inverted into a high level. Since the P-channel MOS TR 4 is turned off attended therewith, the potential at the input terminal is fallen down. The Schmitt trigger circuit having a hysteresis characteristic in this way is obtained.

Title: Toner for developing electrostatic latent image
Inventor: KORI SHUNTARO
IPC: G03G9/097
Filed: 1985-01-25
Abstract: PURPOSE:To obtain a toner for developing an electrostatic latent image having superior resistance to vinyl chloride by which transition is not caused even by contact with a vinyl chloride resin sheet under pressure for a long period by using a coloring agent, a thermoplastic resin having >=9.00 solubility index and alkylenebisfatty acid amide as constituents. CONSTITUTION:This toner contains the coloring agent, the thermoplastic resin having >=9.00 solubility index and alkylenebisfatty acid amide as the constituents. The thermoplastic resin having >=9.00 solubility index is used so as to provide resistance to vinyl chloride to the toner. When the solubility index of the thermoplastic resin is <9.00, the resin is liable to soften with a plasticizer because the solubility index of phthalic ester is about 9.0, and the softening of the resin is not perfectly prevented even by adding the bisamide. In case of heat roller fixing, 5,000-30,000 number average mol.wt. is advantageous to the thermoplastic resin.
