20100239272 | DEVELOPING DEVICE AND IMAGE FORMING APPARATUS - A developing device includes: a developer carrier configured to carry toner; a toner supply member configured to supply developer to the developer carrier; a developing chamber having the developer carrier and the toner supply member; and a sensing device disposed above a toner level in the developing chamber and configured to sense a toner flow. | 09-23-2010 |
20110242196 | INK JET RECORDING METHOD - An ink jet recording method includes ejecting at least two color ink compositions onto a recording medium so as to be deposited one on another. When one ink composition is deposited to form a first image and then another ink composition is deposited to form a second image on the first image, the ink composition forming the second image has a higher yield value than the ink composition forming the first image. | 10-06-2011 |
20110242213 | INK JET RECORDING METHOD - The ink jet recording method includes performing printing by depositing droplets of an ink composition ejected from the ink ejection nozzles on a recording medium transported in the direction perpendicular to the nozzle alignment direction in such a manner that the droplets ejected from at least one ink ejection nozzle located at an end of each of ink jet heads adjacent to each other in the direction perpendicular to the nozzle alignment direction are deposited one on the other. The volume of droplet ejected from the ink ejection nozzle at the end of the ink jet head is smaller than the volume of ink droplet ejected from each of the other ink ejection nozzles of the ink jet head, and the ink composition has a yield value of 0.50 to 2.00 mPa. | 10-06-2011 |
20110254893 | LIQUID EJECTING APPARATUS - The invention provides a liquid ejecting apparatus which can prevent a target having liquid ejected thereon from warping irrespective of the type of the target. An ink jet printer includes a recording head configured to eject ink from a nozzle formed on a nozzle-formed surface onto a recording sheet being transported from an upstream side to a downstream side, and a plurality of supporting belts arranged so as to oppose the nozzle-formed surface and each having a supporting portion extending along the direction of transport of the recording sheet. The respective supporting belts are arranged so as to be capable of moving along the width direction intersecting the direction of transport of the recording sheet. | 10-20-2011 |
20130241991 | INK JET RECORDING METHOD - An ink jet recording method using a recording apparatus including a plurality of ink jet heads, comprising performing printing by depositing droplets of an ink composition ejected from the ink jet heads on a recording medium, wherein the ink jet heads are aligned in a direction cross to a transporting direction of the recording medium and the ink composition has a yield value of 0.50 to 2.00 mPa. | 09-19-2013 |
20130286118 | Ink Jet Recording Method - An ink jet recording method includes ejecting at least two color ink compositions onto a recording medium so as to be deposited one on another. When one ink composition is deposited to form a first image and then another ink composition is deposited to form a second image on the first image, the ink composition forming the second image has a higher yield value than the ink composition forming the first image. | 10-31-2013 |

20110235660 | DRIVER CIRCUIT FOR TUNABLE LD - An LD driver is disclosed where the power dissipation is reduced without enlarging the circuit scale. The LD driver, which drives a tunable LD including a SG-DGB region, a CSG-DBR region, and an SOA region, includes a DC/DC converter connected to current sources or voltage sources each coupled with at least two regions of the SG-DFB, CSG-DBR and SOA regions, and a voltage controller to control the output of the DC/DC converter which is commonly provided to the current sources or the voltage sources. The voltage controller independently monitors the bias conditions of the at least two regions above, and sets the output of the DC/DC converter so as to exceed a largest voltage among voltages currently provided to respective regions by a preset margin to operate the current sources or the voltage sources normally. | 09-29-2011 |
20110254715 | CONTROLLER TO CONTROL ELECTRICAL POWER OF LOAD IN CONSTANT - A heater controller for controlling a heater precisely in the equi-power mode is disclosed. The controller includes a current source, a voltage monitor to detect a voltage drop caused in the heater, and a controller. The voltage drop may be converted to the digital form as refereeing to the first reference, while, the heater current is converted from the digital form as referring to the second reference. The second reference shows substantial temperature dependence, while, the first reference has lesser temperature dependence. The control corrects the temperature dependence of the second reference as referring to the first reference. | 10-20-2011 |
20130070795 | METHOD TO SWITCH EMISSION WAVELENGTH OF TUNABLE LASER DIODE - The method to change the emission wavelength of a tunable LD is disclosed. In an ordinary state, the method monitors conditions not only relating to determine the emission wavelength but conditions independent of the emission wavelength by an ordinary A/D-C implemented within the controller. Responding to an instruction to switch the emission wavelength, the controller only monitors the former conditions affecting the determination of the emission wavelength. The sampling rate of the ordinary A/D-C is equivalently enhanced without installing an additional A/D-C. | 03-21-2013 |
20130094528 | METHOD TO CONTROL EMISSION WAVELENGTH OF TUNABLE LASER DIODE - A method to control the emission wavelength of a tunable laser diode (LD) is disclosed. The method measures the first derivative of the wavelength against the first stimulus, typically a current injected in the SG-DFB region, and the second derivative of the wavelength against the power supplied to the heater in the CSG-DBR region. The method adjusts the current so as to coincide the emission wavelength with the target wavelength, then, corrects the target power for the heater based on the derivative of the current multiplied by a ratio of two derivatives measured in advance to the control of the heater current. | 04-18-2013 |
