A printing apparatus has at least one first recording head and at least one second recording head. These recording heads allow recording in binary mode, halftone mode, normal mode, and fine mode. A printing system has at least two recording units. One recording unit has a plurality of recording heads for recording in yellow, cyan and magenta, and the other recording unit has a recording head for recording in black. Upon a signal scanning operation, the printing system is capable of printing a plurality of copies at high speed and with good quality. A change in size of the original does not result in a problem since the apparatus is capable of feeding a recording paper sheet of corresponding size or printing only for a desired length.
摘要:
An image recording apparatus of the invention has a number of recording units for recording image data of the same or different colors on one or more recording media; a counter to set the number of copies to be produced; and a switch device which selects the recording units to be used in a current recording operation according to the number of copies to be produced and statuses of the respective recording units. A number of copies can be produced simultaneously by the recording units within a period of time shorter than a period of time required for sequentially recording the same number of copies. Dichromatic or polychromatic recording may be freely selected or combined with monochromatic recording by selecting feed paths and an auxiliary path for guiding the recording paper sheet.

A vibration reduction device includes: an elastic body; a dynamic mass; and a controllable mass. The dynamic mass is supported by an object of vibration reduction through the elastic body. An actuator causes the controllable mass to move with respect to the dynamic mass. Such a vibration reduction device can vary the frequency and the amplitude at which the dynamic mass vibrates with respect to the object of vibration reduction by causing the controllable mass to move appropriately with respect to the dynamic mass, thereby enabling vibration of the object of vibration reduction to be reduced more reliably. In addition, such a vibration reduction device can reduce vibration of a certain frequency of the object of vibration reduction even when the controllable mass is fixed with respect to the dynamic mass.

Provided is a control device for an internal combustion engine, employing a microprocessor to control a load other than an ignition device, the control device being provided to an internal combustion engine in which is installed a magnet generator that has a magneto coil for successively generating, in association with revolution of the internal combustion engine, a first half wave voltage, a second half wave voltage of different polarity than the first half wave voltage, and a third half wave voltage of identical polarity to the first half wave voltage; and the magnet generator employing the second half wave voltage to drive the ignition device. The device is provided with an electricity storage element which draws excess power from the output that is output by the magnet generator for the purpose of driving the ignition device, and which is charged by the first and second half wave voltages, as well as being charged by the second half wave voltage as well at times that the internal combustion engine is in the exhaust stroke, in order to supply power to the load and to the microprocessor. The power source circuit is constituted to use the energy stored in this electricity storage element to generate power source voltage for presentation to the microprocessor and to the load other than an ignition device.
摘要:
In order to provide a transmission device and transmission method with which a response signal for random access preamble transmitted from a preamble transmission device is efficiently transmitted, base station (100) sets a first resource candidate group, which enables terminal (200) capable of receiving a latch response transmitted by demodulation reference signal (DMRS) transmission to be selected, and a second resource candidate group, which enables terminal (300) incapable of receiving a latch response transmitted by DMRS transmission but capable of receiving a latch response transmitted by cell-specific reference signal (CRS) transmission to be selected. Base station (100) selects DMRS transmission as the latch response transmission method when a resource in which latch preamble has been received is included in the first candidate group, but selects CRS transmission as the latch response transmission method when the resource is included in the second resource candidate group.

Provided is a relay station that is capable of improving PDSCH channel estimation accuracy, even in a case where a DL grant is provided that gives instructions for downlink data allocation for R-PDCCH. In this device, a signal separation unit (203) receives, of the control information and data and reference signals sent from a base station (100), the reference signals disposed in a first region and a second region within a pre-coding RB group (PRG) comprising one or more PRBs of the plurality of PRBs constituting a divided frequency region; the control information disposed in the first region; and the data disposed in the second region. A demodulation unit (204) demodulates the data on the basis of the reference signals. The demodulation unit (204) demodulates the data using the reference signals disposed in the second region.
摘要:
A method for driving a brushless motor including a first coil and a second coil for two phases but does not include a coil for one of three phases. A three-phase inverter circuit is connected to the first coil and the second coil. Currents having a phase difference corresponding to an electrical angle of 60 degrees are applied to the first coil and the second coil to generate a circular rotating magnetic field.

Provided are a radio transmission device and a radio transmission method capable of improving downlink and uplink throughput even when performing dynamic symbol allocation. In the device and the method, BS and MS share a table correlating a basic TF as a combination of parameters such as TB size used for transmitting only user data, an allocation RB quantity, a modulation method, and an encoding ratio, with a derived TF having user data of different TB size by combining L1/L2 control information. Even when multiplexing L1/L2 control information, Index corresponding to the basic TF is reported from BS to MS.
