  • Patent number: 8681384
    Abstract: For image processing for printing an original, first and second ground patterns are generated. The first ground pattern can be recognized with naked eyes in the original but cannot be recognized with naked eyes in a reproduction of the original obtained by an image forming apparatus, while the second ground pattern has a latent image which cannot be recognized in the original but can be recognized in the reproduction of the original. The first ground pattern and the second ground pattern are synthesized, and print data to be printed by the image forming apparatus is created. The print data has an image of the original, and the synthesized first and second ground patterns.

  • Patent number: 8663858
    Abstract: A fuel cell system which prevents the deterioration of the fuel cell stack when feeding of the oxidant gas is paused under a load to perform a fuel conservation operation. Controller shuts down oxidant gas compressor and cooling water circulating pump to execute fuel conservation operation at a low fuel cell system load. The controller gives a current draw instruction to electric power controller. In the fuel conservation operation, electric power controller draws a current larger than zero from fuel cell stack, and keeps the total charge drawn per unit time constant or substantially constant.

  • Publication number: 20130327180
    Abstract: A multi-shaft drive device is provided that is capable of obtaining an appropriate backlash in an enmeshed state of an output side bevel gear and an input side bevel gear. An output side bevel gear (35) that is biased in the direction of an input side bevel gear by a coil spring contacts a shaft support bush attached to a wall portion (17) in an enmeshed state with the input side bevel gear. A bias direction stroke end of the output side bevel gear (35) is accordingly restricted. Moreover, the wall portion (17) is provided to a gear holder (15) fixed to a device case (10) that supports the input side bevel gear, thereby enabling the axial direction position of the output side bevel gear (35) to always be positioned at a uniform position to enmesh appropriately with the input side bevel gear.

  • Publication number: 20130244127
    Abstract: A fuel cell system is basically provided with a fuel cell, a pressure adjusting valve, a purge valve and an anode pressure controller. The fuel cell includes an anode that receives an anode gas and a cathode that receives a cathode gas to generate electric power corresponding to a load. The pressure adjusting valve is disposed in a supply path to adjust anode gas pressure to the anode. The purge valve is disposed in a discharging flow path to discharge an anode-off gas containing impurities from the fuel cell. The anode pressure controller is configured to control the pressure adjusting valve to perform a pulsation operation that pulsates the anode gas pressure of the fuel cell. The anode pressure controller decreases a median pressure of the pulsation operation as a wetness level of an electrolyte membrane of the fuel cell stack is determined to become higher.

  • Publication number: 20130192418
    Abstract: Force of used spring can be weak, wear amount of power transmission member (gear or the like) can be reduced, and generation of strange noises can inhibited. When the dial cam is rotated and the recess of the outer peripheral surface faces the front end portion of the pin of the connection shaft, the connection shaft, which is biased by the force of the coil spring, is connected to the bevel gear, which engages with the bevel gear and is rotated, via the clutch teeth. Thus, the connection shaft is rotated, and the output shaft is rotated together with the connection shaft. That is, the power of the motor is transmitted to the output shaft. Since the coil spring is used for connecting the connection shaft to the bevel gear, the force of the coil spring can be reduced.

  • Patent number: 8470486
    Abstract: A fuel cell system has a plurality of fuel cells stacked in one or more groups of fuel cells. Each fuel cell includes a fuel electrode supplied with fuel gas at a fuel gas supply pressure, an oxidizing electrode supplied with oxidizing gas at an oxidizing gas supply pressure, and an electrolyte membrane disposed between the fuel electrode and the oxidizing electrode. A pressure-difference control unit generates a pressure difference across the membrane such that the fuel gas supply pressure is greater than the oxidizing gas supply pressure in each fuel cell, a cell-voltage measuring device measures a cell voltage for each fuel cell or each group of fuel cells in the fuel cell stack, and a leakage determination unit determines the presence or absence of a leaking cell based on the behavior of the cell voltage of each fuel cell while the pressure difference is increased with time.
