Provided is a surface processing method of a sputtering target, wherein a target surface in which intermetallic compounds, oxides, carbides, carbonitrides and other substances without ductility exist in a highly ductile matrix phase at a volume ratio of 1 to 50% is preliminarily subject to the primary processing of cutting work, then subsequently subject to finish processing via polishing. The sputtering target subject to this surface processing method is able to improve the target surface having numerous substances without ductility, and prevent or suppress the generation of nodules and particles upon sputtering.

In a certain brake control apparatus, a valve main body of a hydraulic control valve and a coil unit are separately formed, are assembled with each other, and are mounted on an actuator block. Further, bias current is secured even though the supply of current is temporarily unnecessary depending on a control state and a period between the termination and the start of the driving of the hydraulic control valve. Accordingly, it may be possible to maintain a contact state between the inner peripheral surface of the coil unit and the outer peripheral surface of the valve main body during the driving control period.

Provided are a flow meter and a flow-rate control system using the same that is capable of measuring a flow rate in a minute flow-rate region with excellent measurement accuracy by preventing or suppressing the generation of bubbles and in which accumulation of the fluid and the bubbles is less likely to occur. The flow meter is for measuring a minute flow rate of a fluid flowing through a fluid channel whose outlet environment is set to constant pressure, the flow meter including a flow-rate measurement conduit portion having a predetermined length connected to an outlet-side end of the fluid channel 1 and whose outlet environment is set to constant pressure by setting the cross-sectional area of a channel smaller than the fluid channel; a pressure sensor for detecting the pressure of the fluid at the upstream side of the flow-rate measurement conduit portion by being disposed near an outlet of the fluid channel 1; and a pressure-detection control unit 4 for calculating a flow rate from a fluid pressure detected at the pressure detection part.

An ink jet printing apparatus can prevent or suppress the generation, by a reaction liquid and ink, of a reaction product on the face surface of a discharge head, and can remove the ink, the reaction liquid or the reaction product adhering to the face surface so as to constantly maintain a stable printing quality. Immediately before a printing operation is initiated, an anti-coagulation liquid is sprayed on the face surface of a discharge head, and the discharge head performs the discharge operation (printing operation) with the anti-coagulation liquid applied to the face surface. When the printing operation has been completed, or when the printing of a predetermined amount of data has been performed, the face surface of the discharge head is wiped by blades to remove the ink and the reaction liquid. Since the anti-coagulation liquid is applied to the face surface in advance, the generation of the reaction product on the face surface is prevented or suppressed. Furthermore, even when a reaction product is adhered to the face surface, the coagulation of this product on the face surface can be prevented.

The supersonic cleaning of a magnetic head apparatus is executed while the control conductive pattern and the conductive leaf spring are electrically connected by means of soldering, and the conductive leaf spring is grounded. This makes it possible to prevent the accumulation of electrostatic charges in the piezoelectric elements on the magnetic head apparatus, thereby preventing the development of surge current or reducing the intensity thereof, and reducing the damage to the reproducing elements and the recording element mounted on the slider of the magnetic head apparatus.

The present invention provides a hard-to-fall fixing structure of wire harness contributive to cost reduction in which VOC is not generated and flapping sound (noise) of wire harness is hard to occur. In the fixing structure of a wire harness to a vehicle interior material according to the present invention, a silencer pad (acoustical material) is fixed to the vehicle interior material, and the silencer pad is provided with a latching piece formed by cutting a portion of the present silencer pad, and the wire harness is latched to the latching piece.

A vehicle light can include an LED light source disposed such that the optical axis of the LED light source is directed downward, a first lens disposed forward of the LED light source, a second lens disposed below and forward of the first lens, and a first reflector extending from both sides of the LED light source to a position near the optical axis of the LED light source. The first reflector can be configured to reflect light beams from the LED light source toward the first lens so as to form a wide vertically converged and horizontally diffused light distribution pattern. The vehicle light can include a second reflector disposed at a position below and forward of the first reflector. The second reflector can be configured to reflect light beams from the LED light source toward the second lens so as to form a middle-area vertically converged and horizontally diffused light distribution pattern. The lens can be formed by a toroidal lens that is horizontally elongated and that is formed by horizontally extending an aspherical lens cross section having a focus near the LED light source in an arc shape, or by a cylindrical lens having a horizontal focus line. In particular, the lens can be formed by an upper-half lens portion of such a toroidal lens. The vehicle light can include a light shielding shutter having a first upper edge portion and a second upper edge portion lower than the first upper edge portion.

An AlRu sputtering target that is a sintered body composed of an AlRu intermetallic compound of 95 vol. % or more is provided. It is manufactured by a stable and low-cost method that provides it with an even texture, significantly reduces oxygen, prevents or suppresses the generation of particles, and improves the yield ratio of deposition goods.

A sputtering target with low generation of particles in which oxides, carbides, nitrides, borides, intermetallic compounds, carbonitrides, and other substances without ductility exist in a matrix phase made of a highly ductile substance at a volume ratio of 1 to 50%, wherein a highly ductile and conductive metal coating layer is formed on an outermost surface of the target. Provided are a sputtering target capable of improving the target surface in which numerous substances without ductility exist and preventing or inhibiting the generation of nodules and particles during sputtering, and a method of producing such a sputtering target.

Image transfer method and apparatus in which scratches due to entrainment of particles on an image carrier for a toner image having maximum spectroreflectivity at a wavelength of 550 nm do not produce perceptible flaws in resulting images transferred to a recording medium, since images formed with toner of maximum spectroreflectivity at 550 nm on white recording medium are difficult for human eyes to discern. When cleaning residual toner from transfer belts, reverse bias voltage is applied to at least one transfer roller, the peripheral velocity of the photosensitive drum on which a yellow toner image having maximum spectroreflectivity at 550 nm is formed is allowed to differ from the transfer velocity of the transfer belt, and at least the photosensitive drum on which the yellow toner image of maximum spectroreflectivity at 550 nm is formed is detached from the transfer belt.
