A controller controls the solenoid-operated variable pressure relief valves that are provided to control, at set pressures that can be electrically commanded, pressure of hydraulic oil fed to an attachment cylinder. The controller is provided with a control logic that is capable of controlling the aforementioned solenoid-operated variable pressure relief valves. The control logic performs the aforementioned calculation by compensating for pressure override characteristics of each solenoid-operated variable pressure relief valve based on input signals related to the set relief pressure for and a relief valve passing flow rate of the solenoid-operated variable pressure relief valve, and outputting to the solenoid-operated variable pressure relief valve command signals related to the adjusted set relief pressure resulting from the compensation of the pressure override characteristics.

A hydraulic pump driven by an engine, a hydraulic actuator, and a negative control circuit are provided on an open center hydraulic circuit, for guiding the hydraulic pressure in the center bypass to the hydraulic pump, as a negative control pressure. A negative control pressure control device controls the negative control pressure to an arbitrary value is also provided. The pump characteristic of the hydraulic pump is set such that the discharge flow rate is minimized when the negative control pressure in the negative control circuit is equal to or greater than a first predetermined pressure. Furthermore, an idling detection device that detects whether the hydraulic actuator is in a non-operated state or not is provided. The negative control pressure is forcefully controlled to the first predetermined pressure or higher when the non-operating state is detected.
摘要:
An optical line terminal which sends and receives messages or data to/from optical network units (ONUs) connected thereto. A cyclic message monitor produces a trigger signal, for use in a PLOAM grant generator, at certain intervals in harmonization with upstream messages that a specific optical network unit regularly transmits. A downstream message monitor watches outgoing downstream messages to detect a certain message requesting an ONU to return a response, and it triggers the PLOAM grant generator if such a message is detected. An upstream message monitor detects an upstream message whose identification code indicates that the sending ONU has no information to return. If such an upstream message is found, it limits the issuance of PLOAM grants to that optical network unit. The PLOAM grant generator produces PLOAM grants which permit ONUs to transmit their messages, and sends them out through a PLOAM cell transmitter.

A rice polisher for polishing rice, which is a preprocess necessary for producing pre-white rice having a favorable taste by using a small amount of water, a pre-polished rice producing apparatus that uses the rice polisher, a leveling device capable of uniformly leveling grains, and a pre-polished rice producing facility. The rice polisher includes a grain-lifting spiral for transporting white rice above from below, a water-pouring port for pouring polishing water, the water-pouring port being disposed at a head portion, a discharge port for discharging the white rice, the discharge port being disposed at the head portion, and a rice-polishing roll for polishing rice by agitating together with the polishing water poured from the water-pouring port the white rice pressurized by transportation by the grain-lifting spiral, with the polisher discharging from the discharge port the white rice that has been polished.

Disclosed herein is an oil-based solid cosmetic composition comprising the following components (A) and (B): (A) 0.1-10 wt. % of a fluoroalkyl (meth)acrylate copolymer represented by the following general formula (1): ##STR1## wherein R.sup.1 and R.sup.2 are independently a hydrogen atom or a methyl group, R.sup.3 is a hydrocarbon group having 1-32 carbon atoms, R.sub.f is a group obtained by substituting part or the whole of hydrogen atoms of a hydrocarbon group having 1-32 carbon atoms with the corresponding number of fluorine atoms, and n and m are independently a number of 2-2,000 on the average; and (B) 2.9-50 wt. % of a solid oily substance having a melting point of 60.degree.-120.degree. C. The cosmetic composition is good in shape retention and a feeling upon use, has excellent gloss upon its application and can retain the good gloss and color after the application over a long period of time.

A mat with seed is produced by adhering turf seeds onto a nonwoven fabric. Water-soluble adhesives are prevented from being absorbed by the nonwoven fabric to ensure uniform turf surfaces of good appearance. The water-soluble nonwoven fabric is superior in dispersibility, and comprises long fibers having a reduced width and bound with a binder comprising a water-soluble resin and a very small quantity of water repellent reagent such that the long fibers are intertwined in one direction only by foams of water-soluble starch material having a diameter of 7 mm or less.
