The object of the inventioin is to provide a pilot valve which is compact, prevents erroneous operation, and is inexpensive to manufacture. The pilot valve includes a valve body (1), inlet port (2) and outlet ports (3) formed in the valve body, spools (4) operable to interrupt/establish communication between the inlet port (2) and the outlet port (3), pistons (8) for slidably moving the spools (4), a lever (15), and a disk (14) adapted to transmit movement of the lever (15) and having a downwardly directed spherical recess (23). The valve body has a spherical projection (20) pivotably received in the spherical recess (23). A lever mounting shaft (13) is prevented from rotating about its own axis during operation of the lever.

The present invention provides a reversible thermosensitive recording medium including: a support, and a reversible thermosensitive recording layer laid on the support, the recording layer containing a reversible thermosensitive composition, wherein the reversible thermosensitive composition forms a relatively color-developed state and a colorless state depending on a difference in a heating temperature and/or a cooling rate after heating by the use of an electron-donating color-forming compound and an electron-accepting compound; a resin component contained in the reversible thermosensitive recording layer is a resin in which a polyol resin having a hydroxyl value within the range of 100 KOHmg/g to 250 KOHmg/g is crosslinked; and as the electron-accepting compound, a urea compound represented by the following General Formula (1) is used, where “n” is an integer of 23 or greater.
摘要:
A bearing seal includes an outer seal easily displaceable in the radial direction, an inner ring as a ring-shaped rigid portion not extendable in the radial direction, an inner seal having a seal lip, and an outer ring arranged on the outer peripheral portion of the outer seal, in which the spring constant of the inner seal is set to be larger than the spring constant of the outer seal. The sealing performance between the inner seal and the pin is ensured by using the ring-shaped rigid portion as a boundary. When the pin is displaced in the radial direction, the ring-shaped rigid portion is integrally displaced with the pin via the inner seal, and the displacement of the ring-shaped rigid portion can be absorbed by the outer seal.
