摘要:
A steam valve is provided with a valve body, a valve seat, and a valve rod provided for the valve body. The valve body has a bottom portion to which a recessed portion is formed, and the recessed portion has an edge, which is positioned on an upstream side of a place at which a shock wave is generated in steam flowing through a steam path defined by the valve body and the valve seat.

A main steam valve with improved flow characteristic and enhanced reliability comprises a valve seat, a main valve body, and a bypass valve body. A side surface of the bypass valve body slidably fits into the inner surface of the main valve body and forms a steam inlet comprised of a plurality of rows of inlet openings arranged along the side surface. The openings are diametrically symmetrically arranged in the bypass valve, and the positions of the openings in each of the rows are shifted from the positions of openings in the next row.

A hydraulic pressure generating apparatus includes a hydraulic oil feed line for feeding hydraulic oil with high pressure from an oil tank to a hydraulic pressure control system of a generator by an oil feeding pump unit, a hydraulic oil return line for returning drain oil from the hydraulic pressure control system to the oil tank, and a circulation line for circulating and purifying the hydraulic oil of the oil tank by a circulating pump unit. In such apparatus, the hydraulic oil is flame resistant hydraulic oil which is hardly deteriorated by direct heating, and the flame resistant hydraulic oil is heated by a heater disposed in the oil tank.

A method for manufacturing a thermally-assisted magnetic recording head is provided, in which a light source unit including a light source and a slider including an optical system are bonded. A unit substrate is made of a material transmitting light having a predetermined wavelength, and an adhesion material layer is formed on the light source unit and/or the slider. The manufacturing method includes: aligning the light source unit and the slider in such a way that a light from the light source can enter the optical system and the adhesion material layer is sandwiched therebetween; irradiating the adhesion material layer with a light including the predetermined wavelength through the unit substrate; and bonding them. The adhesion material layer melted by the light including the predetermined wavelength and transmitted through the unit substrate can ensure high alignment accuracy as well as higher bonding strength and less change with time.

A solder dispenser provides a cylindrical dispensing container which has a solder inlet for introducing the above-mentioned solder member, and an opening portion for discharging the above-mentioned solder member to the external, and forms an internal space where the solder member can fall between the above-mentioned solder inlet and the above-mentioned opening portion, and a solder supply portion which is detachably mounted in the dispensing container and holds the solder member, wherein, in a state that the above-mentioned lid member is mounted in the above-mentioned dispensing container, the above-mentioned solder supply portion holds the above-mentioned solder member in the opening region of the above-mentioned solder inlet and the above-mentioned internal space becomes a closed space except the above-mentioned opening portion, and wherein, when holding of the solder member is released, the solder member falls inside a closed space to arrive at the opening portion.
摘要:
After photographing a surface on which an ABS is formed, and the outer shape of a slider, the ABS and an engraved region formed within the ABS are identified from a photographed image. A reference that becomes a guide for attaching to a suspension is then computed, and a positional relationship between the reference and the outer shape of the slider is stored as association information. Next, the outer shape of the slider is measured, and measured values are compared to the association information and a reference is read out when attaching the slider to the suspension. An adhesive is discharged, from below, onto a suspension attachment surface of the slider based on the reference. The slider may then be attached to the suspension while holding the slider in a state where the ABS is positioned on an upper side of the slider.

A focus detecting apparatus includes a first object distance measuring zone located above a center portion of the finder field of view, second and third object distance measuring zones located on opposite sides of the center portion of the finder field of view, first, second and third automatic focusing optical systems for converging luminous fluxes of objects to be photographed in first, second and third object distance measuring sensors on which the luminous fluxes of the objects in the first, second and third object distance measuring zones are converged by the associated first, second and third automatic focusing optical systems.
摘要:
A signal processing method for detecting a point of change from a first signal level to a second signal level, outputted from a line sensor having a photoconductive bit element array including setting a threshold level between the first signal level and the second signal level. A pair of bit elements are detected which have outputs that are larger than and smaller than the threshold level. A first line is determined based on the outputs of the pair of bit elements or a pair of bit elements which have a specific relationship to the above-mentioned pair of bit elements. A zero-cross bit element located at an intersecting point of the first line with a zero level is obtained. A second line, which has an inclination angle that is smaller than that of the first line, is determined based on the outputs of the zero-cross bit element and a bit element having a specific relationship to the zero-cross bit element or the outputs of a pair of bit elements having a specific relationship to the zero-cross bit element. A point of change is determined by the intersecting point of the first line and the second line.
