A control valve device comprises two direction control valves. The direction control valve includes an expansion side variable throttle portion and a contraction side variable throttle portion. The direction control valve includes an expansion side variable throttle portion and a contraction side variable throttle portion. When a hoist cylinder is telescopically operated to raise or lower a vessel, as the hoist cylinder approaches a stop position, a controller determines that the hoist cylinder gets close to the stop position. Based upon this determination, the controller variably adjusts a flow passage area of the direction control valve using the variable throttle portions or variably adjusts a flow passage area of the direction control valve using the variable throttle portions in such a manner as to slow down or speed up the telescopic speed of the hoist cylinder corresponding to the weight in the side of vessel.

The novel carbostyril derivative represented by the general formula (1) ##STR1## [in the formula, A, R.sup.1, R.sup.2 and the carbon-carbon bond between 3- and 4-positions in the carbostyril skeleton have the same definitions as above] has an excellent platelet aggregation inhibitory activity, a phosphodiesterase inhibitory activity, a venticular contraction activity (a positive contraction activity), an anti-ulcer activity, an anti-inflammatory activity, a cerebral blood flow increasing activity, a thrombus dissociation activity, a thromboxane A.sub.2 antagonism activity, etc. The carbostyril derivative of the present invention is characterized in that it exhibits the above activities for a long time, is low in toxicity (particularly low in toxicity to hearts of cardiovascular hyperplasia, myocardipathy, etc.), and is low in circulation activities such as heart rate increasing activity, blood pressure decreasing activity and the like. Also, the carbostyril derivative of the present invention has advantages in that it is easily absorbed by the intestinal tract and easily migrates into blood. Therefore, the carbostyril derivative of the present invention can be used most suitably as a preventive and remedy for thrombi such as apoplexia, cerebral infarction, myocardial infarction and the like, a cerebral circulation improving agent, an anti-inflammatory agent, an anti-asthmatic agent, a cardiotonic agent and a phosphodiesterase inhibitory agent.

摘要:
There is provided a circulation line (39) for circulating pressurized oil from an accumulator (11) into a housing (15) of a steering valve (14). An orifice joint (41) is provided along the path of the circulation line (39). The orifice joint (41) is removably mounted on the housing (15) of the steering valve (14) from outside. An orifice portion (42) of the orifice joint (41) applies a throttling function to the circulating oil liquid whereby a frictional heat is generated therein. The oil liquid in a warm state flows through a communication passage (21), passages in a spool valve (16), and a low pressure side passage (18B), thus enabling the steering valve (14) to be always in a warm state.
摘要:
In case a burden is discharged from a vessel (3), the vessel (3) is raised obliquely backward with respect to a vehicle body (2) by a hoist cylinder (10). However, when discharging work is stopped on the way, the vessel (3) is temporarily lowered to a position at which this sits on the vehicle body (2). When the vessel (3) lowers, a weight of the burden left loaded thereon acts on the hoist cylinder (10) as a load in addition to the weight of the vessel (3). A controller (35) determines whether the vessel (3) lowers in a burden loading state based on various detection signals. When the vessel (3) lowers in the burden loading state, switching of directional control valves (20) and (21) is controlled so as to decrease a contracting speed of the hoist cylinder (10), thereby prevent the vessel (3) from colliding against the vehicle body (2).
摘要:
A liquid crystal display unit is used that has data lines made of a molybdenum-alloyed film having a chromium content from 2 wt. % or more, but up to 5 wt. %, or a molybdenum-alloyed film lamination (Mo—Cr) consisting of a first electroconductive film and a second electroconductive film, with the first electroconductive film having a chromium content from 2 wt. % or more, but up to 5 wt. % and the second electroconductive film being provided above the first electroconductive film and containing less chromium than the first electroconductive film does. The use of the data lines composed of these materials enables the following requirements to be satisfied: high dry-etching resistance, low resistance, low ACF contact resistance, low side etching rates, forward tapered wiring cross-sectional shape, and up to two lamination layers.

A wiring of a liquid crystal display device is made of a lamination film including a first layer of Nb or alloy containing Nb as its main component and a second layer of nitride of Nb or alloy containing Nb as its main component. A liquid crystal display device having such a wiring provides a wiring structure excellent in resistance to thermal oxidation.
