A method for manufacturing a silica glass crucible, includes: preparing a crucible base material that is made of silica glass and has a crucible shape; fabricating a synthetic silica glass material based on a direct method or a soot method; processing the synthetic silica glass material into the crucible shape without being pulverized; and bonding an inner wall of the crucible base material and an outer wall of the synthetic silica glass material processed into the crucible shape through a silica powder by performing a heat treatment. As a result, it is possible to provide the silica glass crucible that can avoid occurrence of dislocations of silicon single crystal at the time of manufacturing the silicon single crystal, has high heat-resisting properties, and can suppress a reduction in productivity and yield ratio, the manufacturing method thereof, and the method for manufacturing silicon single crystal using such a silica glass crucible.

An ECU executes a program including the steps of: executing fuel-cut control when an IG OFF operation has been performed and when a vehicle is traveling; executing deceleration control when vehicle speed is equal to or higher than a threshold value; ending the deceleration control and permitting restart of an engine when the vehicle speed has become lower than the threshold value; and controlling a first MG and the engine when an IG ON operation has been performed.

A vehicle is provided with a differential gear including a sun gear, a carrier, and a ring gear, motor generators coupled to the sun gear, an engine coupled to the carrier, and a wheel coupled to the ring gear. The vehicle includes an ECU that stops the engine upon operation of a start switch by a driver, and a brake that brakes the sun gear upon operation of the start switch while the vehicle is traveling.

In a bearing apparatus, a first cup portion defining a portion of a stationary portion of a bearing apparatus includes a circular plate portion and a cylindrical portion projecting downward from an outer edge portion of the circular plate portion. A rotating portion of the bearing apparatus includes an annular recessed portion arranged to accommodate at least a lower end portion of the cylindrical portion. Accordingly, it is possible to limit the axial dimension of the bearing apparatus while also enabling a radial dynamic pressure groove array. Additionally, one end of a through hole defined in the rotating portion is arranged to open into the annular recessed portion.

A manufacturing method of a hermetic container includes steps of bonding a frame member to a first substrate, by pressing the first substrate and the second substrate to each other by an electrostatic force generated between a first electrode and a second electrode by applying a potential difference between the first electrode and the second electrode, and softening and melting the bonding material. Additional steps include cooling and solidifying the bonding material by simultaneously heating the bonding material with a local heating unit and moving the local heating unit, and increasing the potential difference between the first electrode and a segment of the second electrode, which is in a position at which the segment is heated by the local heating unit.

An absorbent article comprising nonwoven fabric having convex and concave surfaces, and that allows liquid such as excreta and the like to permeate quickly. A sanitary napkin has a plurality of raised ridge portions and groove portions in a top sheet member. The fiber density of the side edge portions of each of the plurality of raised ridge portions in the thickness direction of the nonwoven fabric is substantially uniform, and is higher than the average fiber density in the raised ridge portions. The fiber density of the central portion between both the side edge portions of each of the plurality of raised ridge portions is substantially uniform in the thickness direction of the nonwoven fabric, and is lower than the average fiber density in the raised ridge portions.

A seat track mechanism for a vehicle, includes a lower rail mounted to a vehicle floor; an upper rail supported by the lower rail and slidable relative to the lower rail; and spherical rotators held between the lower and upper rails, the spherical rotators rolling via a sliding movement of the upper rail. One of the upper rail and the lower rail includes at least one horizontal flat portion parallel to a widthwise direction of the seat track mechanism and parallel to a direction of the sliding movement of the upper rail, and the other of the upper rail and the lower rail includes at least one rotator supporting recess having a circularly arcuate shape in cross section which is uniform in a lengthwise direction of the seat track mechanism, the spherical rotators being held between the rotator supporting recess and the horizontal flat portion.
