摘要： The mechanical seal (3) includes: a rotary side sliding ring (32) which is supported by the large diameter side outer circumferential face (23) of the annular step section (21) of the rotary shaft (2) via the rotary side O-ring (37) and press-fitted into the annular step section (21) by gas pressure in the device; and an unturnable stationary side sliding ring (31) which is fixed onto the seal housing (1) side via the stationary side O-ring (33) being capable of moving in the axial direction and being able to come into close contact with the sliding protrusion (323) of the rotary side sliding ring (32) due to the spring (36) so that the airtightly sealed sliding face S is formed. The rotary side sliding ring (32) is made of self-lubrication sliding material, and the stationary side sliding ring (31) is made of sliding material, the Young's modulus of which is higher than that of the self-lubrication sliding material. A deforming force given to the rotary side sliding ring (32) in the leaning direction caused by differential pressure between the high gas pressure and the atmospheric pressure outside the device is canceled by a deforming force caused by a component in the axial direction of the differential pressure acting on the annular step section (21) of the rotary shaft (2) in the pressing direction.
摘要翻译：机械密封件（3）包括：旋转侧滑动环（32），其经由旋转侧O的旋转轴（2）的环状台阶部（21）的大直径侧外周面（23）支撑（37），并通过装置中的气体压力压入环形台阶部分（21）; 以及经由固定侧O形环（33）固定在密封壳体（1）侧上的能够沿轴向移动并能够与滑动件紧密接触的不可转动的固定侧滑动环（31）由于弹簧（36）使旋转侧滑动环（32）的突起（323）形成为气密密封的滑动面S。旋转侧滑环（32）由自润滑滑动材料制成，固定侧滑环（31）由滑动材料制成，杨氏模量高于自润滑滑动材料。由装置外部的高气体压力和大气压之间的压差引起的向倾斜方向施加的旋转侧滑环（32）的变形力由于差速器的轴向方向的分量引起的变形力而被抵消作用在旋转轴（2）的环状台阶部（21）上的加压方向的压力。

摘要： First pumping threads are formed on an inner circumferential surface of the seal lip portion of an elastomer lip member. The first pumping threads generate a pumping action in a leakage direction when a shaft rotates. A first resin lip member is arranged at a rear side of the elastomer lip member. Second pumping threads generate a pumping action in a direction opposite to the leakage direction when the shaft rotates. The second pumping threads are formed from an inner circumferential surface of a seal lip portion of the first resin lip member to a rear portion of a bent portion thereof. A second resin lip member is arranged at a rear side of the first resin lip member and has a surface sliding on the shaft, which is formed smoothly.

摘要： A first swash plate 18 is coupled to a drive shaft 16 to be rotatable integrally with the drive shaft 16. Single head pistons 23 are coupled to the first swash plate 18 via shoes 25A, 25B. Rotation of the drive shaft 16 rotates the first swash plate 18, which causes the pistons 23 to reciprocate and compress refrigerant gas. The first swash plate 18 supports an annular second swash plate 51 to be rotatable relative to the first swash plate 18 via a ball bearing 52. The second swash plate 51 is arranged between the first swash plate 18and the shoes 25B that receive a compressive load to be slidable with respect to the first swash plate 18 and the shoes 25B. Therefore, the first swash plate reliably slides with respect to the second swash plate.

摘要： A shaft sealing assembly is located in a suction chamber of a swash plate type compressor to seal the space between a drive shaft and a housing. A first end portion of the drive shaft is supported by a first radial bearing. A second end portion of the drive shaft is supported by a second radial bearing. The suction chamber is closer to the first end portion of the drive shaft than the first radial bearing is. An axial passage is formed in the drive shaft to connect the suction chamber to the crank chamber. An inlet of the axial passage is closer to the second end portion than the second radial bearing is. An outlet of the axial passage is closer to the second end portion than the first radial bearing is.

摘要： A shaft seal seals a rotary shaft surface to prevent fluid from moving between a high-pressure area and a low-pressure area. The shaft seal has a lip type ring fitted on the side of the high-pressure area of the rotary shaft. The lip type ring further includes a lip ring, a plurality of first portions and a plurality of second portions. The lip ring is located around the rotary shaft. The lip ring has a ring surface. The first portions are formed on the ring surface to slidably contact the rotary shaft surface. The first portions guide the fluid towards a space between the ring surface and the rotary shaft surface as the rotary shaft is rotated. The second portions are formed on the ring surface. The second portions prevent the fluid in the space from leaking into the low-pressure area.

摘要： In making a contact determination between an object and a display screen, a display apparatus of the present invention is capable of adjusting a region on which to make a contact determination in response to the displayed image in a liquid crystal panel, so that the influence by the displayed image can be suppressed. Moreover, for simplifying the contact determination process, the display apparatus sets solid a region in the picked-up image that is not a target of the contact determination, with a predetermined gradation value.
