A swivel assembly of a vehicle seat including a ring-shaped upper plate fixed to a seat side member of a vehicle; a ring-shaped lower plate fixed to a floor side member of the vehicle; and a set plate holding the upper plate between it and the lower plate. One ball is provided between the upper plate and the lower plate. The other ball is provided between the upper plate and the set plate. The other ball is in contact with both inner surfaces of each of one sectionally V-shaped guide groove and the other sectionally V-shaped guide groove confronting the one groove. The upper plate can be held at a predetermined position without being loosened vertically and horizontally even though the upper plate, the lower plate, and the set plate have errors occurred in manufacture.

An agent for treating or preventing cerebral circulation disorder, cerebral metabolism disorder, or memory disturbance is disclosed. The agent comprises as an effective component a phenylalkanoylamine derivative represented by the following formula (I), ##STR1## wherein A represents a 1,3-thiazolidin-3-yl group, a 1,2,3,6-tetrahydropyridin-1-yl group, a morpholino group, a thiomorpholin-4-yl group, or a 3-pyrrolin-1-yl group, R.sup.1 and R.sup.2, which may be the same or different, represent a hydrogen atom, a halogen atom, a lower alkyl group, a lower alkoxy group, a nitro group, an amino group, a guanidino group, or a group ##STR2## (wherein R.sup.3 and R.sup.4 independently represent a lower alkyl group or form in combination 5- or 6-membered heterocyclic group), and n represents an integer of 2-6, or a salt thereof. This agent is effective for treating or preventing cerebral hemorrhage sequela, cerebral infarction sequela, cerebral arterioscleosis, subarachnoid hemorrhage sequela, cranial injury sequela, cerebral operation sequela, cerebrovascular dementia, Parkinson's disease, Alzheimer's disease, Pick's disease, various anoxia toxicosis including, but not limited to anthracemia sequela, cerebral alcoholism related diseases, and the like.
摘要:
A slide device, comprising first class members having spaces opening to sides formed in the longitudinal directions thereof and second class rail members positioned in the spaces, wherein either of the first and second class rail members movable relative to each other are formed in movable rail members and the other are formed in fixed rail members, the movable rail members are installed at both side parts of slide plates, the slide plates are positioned on brackets parallel with each other, and the movable rail member installed on the slide plate is supported by the fixed rail member installed on the slide plate.

A vibration damping mount capable of reducing vibration and noise, and improving vehicle stability and controllability. Between an inner cylindrical sleeve and outer cylindrical sleeve which are coaxially arranged with each other, a vibration-damping rubber body is disposed and joined thereto. A stopper plate is secured to a lower end of the inner cylindrical sleeve. The vibration-damping rubber body extends from the lower end thereof along a flange which projects outward from a lower end of the outer cylindrical sleeve to define an annular rubber stopper. An end edge of the annular rubber stopper abuts a peripheral part of the stopper plate. A rubber spacer is disposed in an annular space defined by the rubber stopper, vibration-damping rubber body and stopper plate so as to be compressed and generate a reaction force upon obliquely applied loads due to the relative displacement between the inner sleeve and outer sleeve, thereby reducing vibration and noise with friction damping, and improving vehicle stability and controllability against the obliquely applied loads by applying an increased spring constant upwardly.

A heald frame comprises: a heald support frame for supporting a plurality of healds in parallel, the heald support frame having a central plate portion and a pair of ring-shaped rectangular heald supporting portions extending in opposite directions from the central plate portion; and a heald support extending perpendicularly from the central plate portion, the heald support being integrally connected to the central plate portion of the heald support frame via a generally V-shape joint. The heald frame is made from a reinforced composite material composed of a synthetic resin and a reinforcing filler. Each of the heald supporting portions includes one lower supporting rod for supporting at least a heald.
摘要:
Water containing nutrients is added to powdered activated carbon or passed through a layer of granular activated carbon for clarification, and water cultivation is effected in facilities by supplying the nourishing water in a water cultivation vessel, inserting seedlings of vegetables to a water cultivation panel installed above the vessel, and, if necessary, providing atmospheric conditions, water temperature and water quality suitable for the growth of the seedlings.
摘要:
An oil pan structure includes a tubular level-gauge guide into which an oil level-gauge that measures the amount of oil stored in the oil pan is inserted. The oil pan structure further includes a nozzle guide that guides the end of a nozzle of an oil changer, which is inserted into the level-gauge-guide when the oil in the oil pan is replaced with new oil, to a position near the deepest portion of the reservoir portion.
摘要:
The liquid-sealing type vibration isolating apparatus of the present invention includes a coupler configured to be attached to a vibrating body, a holder, an insulator for absorbing and isolating vibration from the vibrating body at a position between the coupler and the holder, and a vibration isolating mechanism directly following the insulator and including liquid chambers sealing an incompressible fluid. This vibration isolating mechanism has a main chamber sealing a liquid, having a part of a wall thereof formed by the insulator, an auxiliary chamber communicating with the main chamber via an orifice, and an equilibrium chamber provided in a portion of the main chamber via a diaphragm and having a varying volume in the chamber. The vibration isolating apparatus further includes a switching mechanism for introducing a negative pressure and the atmospheric pressure continuously or in synchronization with vibration of the vibrating body, and a control mechanism for controlling this switching operation.
