  • Patent number: 7852504
    Abstract: When the image forming device receives a print job including a print condition in its header, an operation control section extracts the print condition from the header, and makes an inquiry to a server. The server extracts an order table, indicative of a priority based on the extracted print condition, from a setting table in which a priority of sheets has been set in advance in accordance with the extracted print condition, and sends the order table by return to the image forming device. In the image forming device, a tray selection section generates a tray selection signal in accordance with the received order table and a detection signal, outputted from a tray detection section, which functions as sheet storage information of a sheet feeding tray section, so as to send the tray selection signal by return to the sheet feeding tray section.

  • Patent number: 7841256
    Abstract: A miniaturized articulated manipulator 20 has a first arm member 31A internally provided with two driving motors 33 and 34, and a second arm member 30B not provided with any devices corresponding to the driving motors 33 and 34 and capable of being miniaturized. The driving motors 33 and 34 can be disposed in common areas 135 at least partially overlapping each other with respect to a direction parallel to the axis of the first arm member 30A and can be arranged in a direction perpendicular to the axis. Thus the first arm member 30A can be formed in a small axial size. Thus the first arm 30A and the second arm 30B can be miniaturized and hence the articulated manipulator 20 can be formed in a short overall length.

  • Patent number: 7801314
    Abstract: In an audio signal encoding apparatus, a first audio signal and a second audio signal are added into an addition-result signal. The first audio signal is subtracted from the second audio signal to generate a subtraction-result signal. A first difference signal is generated which represents a difference in the addition-result signal. A second difference signal is generated which represents a difference in the subtraction-result signal. A plurality of first predictors have different prediction characteristics respectively, and are responsive to the first difference signal for generating first different prediction signals for the first difference signal, respectively. A plurality of first subtracters operate for generating first prediction-error signals representing differences between the first difference signal and the first different prediction signals, respectively. A first minimum prediction-error signal representative of a smallest difference is selected from among the first prediction-error signals.

  • Patent number: 7792416
    Abstract: DVD-video data and DVD-audio data are recorded in a DVD-Avd disc. The DVD-audio data is composed of an audio manager having an audio manager information, an audio manager menu, a first audio title set including first audio data and a second audio title set including second audio data. The first audio data of the first audio title set is connected with audio contents included in the DVD-video data, and a real time information (RTI) pack or a still picture (SPCT) pack is included in the second audio title set. Therefore, the audio contents of the DVD-video data and the audio data of the DVD-audio data are managed by the audio manager information, and text information indicated by real time information or a still picture is displayed while reproducing the audio data. Also, DVD-video data recorded in a DVD-video disc, which is normally reproduced by using a reproducing apparatus dedicated to the DVD-video disc, can be reproduced by using a reproducing apparatus for the DVD-Avd disc.

  • Publication number: 20100210064
    Abstract: In order to manufacture a CIS-based thin film solar cell that can achieve high photoelectric conversion efficiency by adding an alkali element to a light absorbing layer easily and with good controllability, a backside electrode layer (2) is formed on a substrate (1). Then, a p-type CIS-based light absorbing layer (3) is formed on backside electrode layer (2), and then an n-type transparent and electroconductive film (5) is formed on this p-type CIS-based light absorbing layer (3). At this time, the backside electrode layer (2) is constituted by forming a first electrode layer (21) using a backside electrode material in which an alkali metal is mixed and, then forming a second electrode layer (22) using the backside electrode material that does not substantially contain the alkali metal.

  • Publication number: 20100176105
    Abstract: A superimposed voltage waveform with a predetermined cycle and amplitude is superimposed on a commanded voltage waveform for a second predetermined time after a first predetermined time elapses within an arcing period in which an arc is produced. The predetermined cycle of the superimposed voltage waveform is shorter than a short-circuit cycle and longer than a control cycle of a welding power supply unit. This suppresses a growth of a weld droplet by being pushed up toward a consumable electrode and suppresses an excessive growth of the droplet over an entire range from a low current range, characterized by frequent short-circuits, to a medium to high current range where short-circuits are less frequent. The droplet is also smoothly transferred to the weld pool in addition to preventing excessive droplet growth. This reduces the generation of spatter, giving a flatter bead appearance.

  • Patent number: 7753013
    Abstract: A variable compression ratio engine. The engine includes a piston disposed in a cylinder bore and constituting a combustion chamber, a variable compression ratio mechanism connected to the piston and causing a top dead center position of the piston to vary, an actuator connected to the variable compression ratio mechanism to actuate the variable compression ratio mechanism, and a controller connected to the actuator to control an engine state and the actuator. The controller performs operations including setting the compression ratio corresponding to a state of the engine, actuating the actuator so that the compression ratio is set, determining whether a state of the engine is either a state allowing actuation of the actuator, or a state limiting actuation of the actuator, and limiting actuation of the actuator in the state limiting actuation of the actuator.
