When fed in the direction indicated by the arrow, fuel gas is first allowed to flow through a fuel-electrode side gas passageway 14a partitioned by the plate 10, a fuel electrode and the separator 13 and through a separator side passageway 14b, and hydrogen is consumed inside the passageway 14a. Therefore, water and carbon dioxide are generated from the electrode surface and hydrogen concentration is gradually decreased, but since the gas allowed to flow through the passageway 14b is allowed out of the openings 11,12 at a portion 50cm away from the fuel gas inlets and flows through the passageway 4a, the concentration of the hydrogen gas is raised again. Gas concentration and current density on the electrode surface are thereby uniformed so as to achieve high performance of a molten carbonate fuel cell and to facilitate the manufacture of the fuel cell.

Title: Led driving circuit of led printer
Inventor: IKEZOE YOSHIAKI
IPC: B41J2/45
Filed: 1990-03-29
Abstract: PURPOSE:To finely express the gradation of printing without increasing the number of LEDs by changing LED driving pulse width according to printing gradation data to change density in an one dot unit. CONSTITUTION:A printing gradation register 3 is a register holding printing gradation data and outputs the printing gradation data to a microprocessor 4. The microprocessor 4 sets the time driving an LED 12 to a timer 5 according to the printing gradation data. A drive circuit 6 outputs the time pulse set by the timer 5 to an AND circuit 8 to drive the LED 12. When the driving pulse width of the LED 12 is set to A, B, C, the luminous intensity of the LED changes to D, E, F. When the luminous intensity of the LED 12 changes, density also changes in proportion to the change of said luminous intensity and, therefore, gradation is carried out in three stages in this case by the setting of the pulse widths A, B, C. As mentioned above, by setting the time of a drive pulse to the timer 5 according to printing gradation data, gradation printing can be easily carried out.

Title: Internal combustion engine
Inventor: ICHINOSE HIROKI
IPC: F02B29/02
Filed: 1995-04-07
Abstract: PURPOSE: To perform ensurance of excellent combustion operation during low load operation of an engine as an air-fuel ratio is prevented from being brought into a lean state during the starting of the engine. CONSTITUTION: An intake air flow control valve 17 is located in an intake branch pipe 10 between a throttle valve 15 and a fuel injection valve 14. During the starting of an engine, the opening of the intake air flow control valve 17 is held in a fully closed state and this operation limits an amount of air fed in a combustion chamber 4 during the starting of en engine. When, after the starting of an engine is completed, an engine load is below a set load, the opening of the intake air flow control valve 17 is held in a half opening state. In this case, air A flowing through the intake air flow control valve 17 is guided toward injected fuel F and collision of the air A with the injected fuel F promotes atomization of the injected fuel F.  When an engine load exceeds a set load, the opening of the intake air flow control valve 17 is held in a full opening state to prevent an intake air amount from being insufficient.
