摘要:
An ink jet recording head has an array of ink ejection outlets in an ejection outlet forming surface, to which a protection tape is adhered during transportation. The ejection outlet forming surface has an outside area which is outside of each of opposite ends of the array with respect to a direction of the array, and the outside area has a peel resistance, provided by surface modification, which resistance is higher than in another portion of the ejection outlet forming surface.

To provide a sound collection system using a plurality of microphones arranged in the proximity to one another and having an excellent directivity for an arbitrary position in the sound field space. A plurality of control points are set around a plurality of sound collecting microphones. A desired response function matrix A(ω) and a transfer function matrix C(ω) between the control points and the respective microphones are measured. A control filter H arranged in a digital signal processing unit (2) is connected to each of the microphones constituting the sound collection device (1). The control filters H are arranged for the number of output channels of a reproduction unit (4). An output of each of the control filters H is added for each channel and outputted to each channel of the reproduction unit (4). By specifying a microphone directivity upon sound collection at a control point, the control filters H are decided according to the measured desired response function matrix A(ω) and the transfer function matrix C(ω) of the specified control point.

A group information generating system 1 comprises a group border information generating units 9 or 10 and a group information generating unit 12. The group border information generating unit 9 or 10 is configured to generate a border information indicating at least one border of group when medical images sorted into the group are to be indicated according to an information included in a medical image information. The group information generating unit 12 is configured to generate a group information according to the border information. The group information means a discernment information of the group to which an image indicating information included in the medical image information for indicating one of the medical images is belong.

The present invention is concerned with an axial-flow or mixed-flow inducer (3) which is disposed upstream of a main impeller (2) for improving the suction capability of a pump such as a turbopump. In the inducer (3), a blade angle (βbt) from a tip (T1) to a hub (H1) at a blade leading edge (31) is substantially the same as an inlet flow angle (β1−t) at a designed flow rate.

摘要:
Electrodes are embedded respectively in a first die and a second die. A metal workpiece is placed in a cavity defined between the first die and the second die which mate with each other. Then, a molten metal is poured through a passage into the cavity. The molten metal is solidified into a casting, forming a contact region of the metal workpiece and the casting. Thereafter, an electric current is supplied from a power supply between the electrodes across the contact region. The supplied electric current breaks an oxide film that is present on the surface of the metal workpiece, and joins the metal workpiece and the casting in the contact region.

Disclosed is an impeller for a turbomachine. The impeller comprises a hub, full blades equidistantly disposed on the hub in a circumferential direction, and a splitter blade disposed between each adjacent two of the full blades. The splitter blade is shaped in such a way that a spanwise distribution of a pitchwise position of a leading edge of the splitter blade is determined according to a spanwise and pitchwise non-uniformity distribution of fluid velocity of a fluid flowing into the splitter blade, whereby a non-dimensional circumferential position of a leading edge of the splitter blade varies in a spanwise direction.
