CONSTITUTION:A digital signal light sequence 11 which is inputted to a 1st input terminal and control light 12 which is synchronized with signal light to be separated from the digital signal light sequence 11 are multiplexed by an optical multiplexer 13 and entered into an optical multi-stable semiconductor laser 14. Its light output is made incident on a wavelength filter 15, the optical multi-stable semiconductor laser 14 does not oscillates regardless of the input of the control light 12 when the signal light 11 is '0', and its output is '0'. When only the signal light 11 is inputted, on the other hand, the laser oscillates with 1st wavelength and its output appears at an output terminal 16 where only the 1st wavelength of the wavelength filter 15 is passed. Further, when the signal light 11 and control light 12 are made incident at the same time, the laser oscillates with 2nd wavelength and its output is sent out through an output terminal 17 where only the 2nd wavelength of the wavelength filter 15 is passed. Consequently, the necessary light signal is separated under the optical control.

Title: Heat and electric power combined
Inventor: SOGA YUKITERU
IPC: H01M8/04
Filed: 1992-06-29
Abstract: PURPOSE:To stably take out high temperature steam of 150-170 deg.C without affecting a fuel cell body, and supply it to the outside by providing a heater using the same fuel as the main body upstream of a steam separator provided in a cooling water system for cooling the cell body. CONSTITUTION:Upstream of a steam separator 2 of a cell cooling water system, a gas burning heater 4 is arranged. At the time of a fixed electric output (less than about 75% output), two-phase flow steam of a cell cooling water is further heated by the heater 4 using the same fuel as a fuel cell body 1 to stably generate a high temperature (150-170 deg.C) steam from the separator 2. Since the gas burning heater 4 is more efficient than an electric heater, the temperature raising time of the cell cooling water can be shortened, less fuel can be used, and the cost can be reduced. Since no high temperature steam is generated at a low electric output (about 50% output or less), the high temperature (150-170 deg.C) steam can be stably supplied to the outside even in the case of a low power output (less than about 75% output) and even when heat generation quantity of the cell is changed by fluctuation of load.

Patent JP-S6327272-A (JP)
Title: Thermal printer
Inventor: SOMA TAKAHIRO
IPC: B41J2/37
Filed: 1986-07-21
Abstract: PURPOSE:To prevent the irregularity of printing density due to the exhausion of a battery, by changing a printing compensation current according to the voltage drop of a battery power source and compensating a printing pulse width according to said printing compensation current. CONSTITUTION: In order to compensate the lowering in the voltage V1 of a battery exhausted, a current supply circuit is equipped with a current supply source 13 operated on the basis of the difference between battery voltage V1 and the output V2 of a voltage regulator. The current supply source 13 comprises a series circuit of a non- linear element (e.g., constant voltage diode ZD) and a resistor R3 and, when the voltage V1 of the battery is low and the constant voltage diode ZD is held to an ON-state, the current determined by the resistor R3 flows in the base of a transistor Q and a current charging a condenser C is made large. Therefore, a printing pulse width becomes short and a thermal head 4 is driven so as to consume constant power. Since the inverse characteristic of the constant voltage diode ZD is used at a relatively smooth part, control can be performed so as not to generate sudden compensation. However, since a compensation current changes non-linearily, said current has a compensation width sufficient to compensate the voltage of the battery lowered by exhausion.
