Abstract: The ceramic sintered body contains Zr, Al, Y, and Mg. A Zr content is 7.5 mass % or more and 23.5 mass % or less in terms of ZrO2. An Al content is 74.9 mass % or more and 91.8 mass % or less in terms of Al2O3. A Y content is 0.41 mass % or more and 1.58 mass % or less in terms of Y2O3. A Mg content is 0.10 mass % or more and 0.80 mass % or less in terms of MgO. A ZrO2 crystal phase as a crystal phase has a monoclinic phase and a tetragonal phase as crystal structures. When a thermal aging treatment is performed for 100 hours in an environment of 180 degrees C., a ratio of a peak intensity of the monoclinic phase to a sum of peak intensities of the monoclinic phase and the tetragonal phase is 15% or less in the X-ray diffraction pattern.

Abstract: To provide an exercise garment with crotch part that is capable of sufficiently improving performance of various types of exercises accompanied by three-dimensional movements such as rotation of the trunk and rotation/outward rotation/inward rotation of both legs. In an exercise garment with crotch part, when it is being worn, tightening forces of first tightening portions act on the muscle groups existing around the greater trochanter, so that the muscle groups are supported to broaden the extent of mobility of the pelvic band. On the other hand, on the inside of the closed-loop first tightening portions, the space between a first line and a second line gradually becomes wider toward the greater trochanter position, whereby a side hole is formed. Due to such formation of the side hole, the greater trochanter of the wearer is prevented from being pressed directly by the first tightening portions.

Abstract: It is an object of the present invention to provide a process for producing propylene glycol from glycerol as a raw material without the necessity for a step of gasifying glycerol. The process for producing propylene glycol of the present invention comprises a step of subjecting glycerol to catalytic hydrogenation in the presence of a catalyst A containing zinc oxide, silica, and at least one of copper and copper oxide.

Abstract: An exercise garment according to which the exercise performance in various types of exercise accompanied by rotation of the trunk and movement of the arms can be sufficiently improved. The exercise garment includes first tightening portions exerting tightening forces on the scapulae and scapula-surrounding muscle groups, so that the scapulae and the scapula-surrounding muscle groups are supported such that the extent of mobility of the scapulae is broadened. The tightening force due to one of the first tightening portions is transmitted to the other first tightening portion via second tightening portions. As a result, movement of one scapula linked to the movement of the other scapula is promoted, and the extent of mobility of the scapulae is further broadened. Consequently, the flexibility around the shoulders during exercise in which the left and right shoulders are working together can be effectively increased.

Abstract: There is provided an exercise garment according to which the exercise performance in various types of exercise accompanied by rotation of the trunk and movement of the arms can be sufficiently improved. With the exercise garment 1, when the exercise garment 1 is being worn, tightening forces due to first tightening portions 21 act on the scapulae and the scapula-surrounding muscle groups, so that the scapulae and the scapula-surrounding muscle groups are supported such that the extent of mobility of the scapulae is broadened when the wearer cares out rotation of the trunk or movement of the arms. Moreover, the tightening force due to one of the first tightening portions 21 is transmitted to the other first tightening portion 21 via second tightening portions 22. As a result, movement of one scapula linked to the movement of the other scapula is promoted, and hence the extent of mobility of the scapulae is further broadened.

Abstract: A magnetic disk drive of the Winchester type has magnetic disks layered around the external peripheral surface of a spindle and separated mutually from one another by spacers. The substrate of the magnetic disks are made of non-metallic materials such as glass or ceramics but do not break easily by the motion of the spindle or the change in temperature because either the adhesive used to form a unistructural assembly of the magnetic disks and the spacers or elastic members inserted in annular indentations formed in the spacers serve as a buffer when the magnetic disks and the spacers are compressed together.
