    摘要: A variable displacement vane pump includes a rotor, a cam ring; and a pump casing including first and second side walls disposed on both sides of the cam ring, and a circumferential wall surrounding the cam ring and defining first and second pressure chambers. A pressure introduction groove is formed in a sliding contact surface between the cam ring and one of the first and second side walls, and arranged so that a pressure lower than an outlet pressure is introduced.

    摘要: In a chromating solution comprising a water-soluble chromium compound and a reducing agent and in which hexavalent chromium ions produced by dissolution of the water-soluble chromium compound have been partly reduced with the reducing agent to trivalent chromium ions, an oxycarboxylic acid compound is used as the reducing agent. This chromating solution causes neither gelation nor sedimentation of the solution even when hexavalent chromium ions are reduced to trivalent chromium ions at a reduction percentage of more than 50%. The chromating solution and a chromate film formed on a steel sheet may also contain an organic resin, phosphoric acid or a phosphoric acid compound, or a silica sol.

    摘要: In a flow control valve, a valve spool is movable for variably controlling an opening area of a port portion of a drain passage so that a necessary flow rate of fluid is conducted from a first pressure chamber to an outlet passage through a control orifice while a surplus flow rate of fluid is returned from the first pressure chamber to the drain passage. A movable sleeve is installed in a valve spool accommodation hole and around the valve spool. The movable sleeve has through holes communicable with the drain passage and an inlet passage, respectively. The movable sleeve has a first axial end portion disposed in the first pressure chamber and a second axial end portion disposed in a low pressure chamber. A spring is disposed in the low pressure chamber for urging the movable sleeve toward the first pressure chamber side. The movable sleeve is movable relative to the valve spool in response to a variation of pressure in the first pressure chamber for varying the opening area of the port portion of the drain passage.

    摘要: A pine extract combined with a bamboo extract and/or a Japanese apricot extract effectively promotes the growth and regeneration of hair for human and animals. Administration of these compounds leads to no substantial side effects. The topically applied hair restorer containing these compounds is also effective in the prevention of alopecias, as well as in the protection of falling out of hair, dandruff, and itching of the scalp. These properties render these compounds useful in hair restorers for human and animals.
