A printer apparatus is provided which receives concurrent input print data from plural input ports without increasing receiving buffer memory. A controller determines whether an image creator is used by other jobs when starting receiving print data through any one of the plural input ports. When not used, print data related to the current job is stored in a receiving buffer memory and at the same time print data stored in the buffer memory is printed via the image creator. On the other hand, when other jobs use the image creator, the print data related to the current job is stored in a hard disk unit and is printed when the image creating device becomes available.

In the present invention, provided is a semiconductor device, including: a GaN channel layer which is provided on a substrate and through which electrons run; a barrier layer which is provided on the GaN channel layer and which contains at least one of In, Al, and Ga and contains N; a gate electrode which is provided on the barrier layer; and a source electrode and a drain electrode which are provided on the substrate across the gate electrode, in which, in a portion of the barrier layer between the gate electrode and the drain electrode, a magnitude of polarization of the barrier layer is smaller on the gate electrode side than on the drain electrode side. Thus, PAE can be improved by reducing Rd and Cgd simultaneously.

A transmission module including a power supply voltage control unit that sets a power supply voltage to the high frequency amplifier in a variable manner, and a control circuit that controls an amplitude control unit, a phase control unit and the power supply voltage control unit. The control circuit and the power supply voltage control unit control the power supply voltage in accordance with an output power of the high frequency amplifier. The transmission module can carry out not only phase control but also amplitude control in a continuous manner, while suppressing amplitude and phase variation, and a high frequency amplifier in the transmission module is made highly efficient. In addition, a large directional gain, a low side lobe level and a low power consumption are achieved, as a phased array antenna apparatus using a transmission module.

It is an object to provide an epitaxial silicon wafer that is provided with an excellent gettering ability in which a polysilicon layer is formed on the rear face side of a silicon crystal substrate into which phosphorus (P) and germanium (Ge) have been doped. A PBS forming step for growing a polysilicon layer is executed on the rear face side of a silicon crystal substrate into which phosphorus and germanium have been doped at a high concentration to execute a baking treatment. After a surface layer of the silicon crystal substrate is then polished up to a predetermined amount, a silicon epitaxial layer is grown by a CVD method. By the above steps, the number of LPDs (caused by an SF) that occur on the surface of the epitaxial silicon wafer due to the SF can be greatly reduced.

摘要:
A high pressure fuel pipe construction for an internal combustion engine, such as a direct injection engine. A conduit for the fuel is open at each end and a ball having a throughbore is slidably positioned over one end of the conduit. A reinforcing sleeve is positioned inside the end of the conduit so that the sleeve extends entirely through the ball. The sleeve, ball and the end of the conduit are then brazed together to attach the ball and conduit together. A double chamfer is provided at one end of the ball throughbore to facilitate inspection of the brazing quality. Additionally, a loop is formed in the conduit and a dampener is attached to the loop.

A task is to correctly classify an input image regardless of a fluctuation in illumination and a state of occlusion of the input image.Input image sub-region extraction means 2 extracts a sub-region of the input image. Inter-pattern distance calculation means 3 calculates an inter-pattern distance between this sub-region and a sub-region of a registration image pre-filed in dictionary filing means 5 for each sub-region. Region distance value integration means 10 integrates the inter-pattern distances obtained for each sub-region. This is conducted for the registration image of each category. Identification means 4 finds a minimum value out of its integrated inter-pattern distances, and in the event that its minimum value is smaller than a threshold, outputs a category having its minimum distance as a recognition result.
