A power steering device for use with a boat propulsion unit has a hydraulic cylinder unit for angularly moving a steering arm of the boat propulsion unit. A rotary valve mechanism for supplying working oil from a working oil tank to the hydraulic cylinder unit and discharging working oil from the hydraulic cylinder unit to the working oil tank comprises a flat valve body having oil holes defined transversely therethrough and a valve housing assembly housing the flat valve body and having ports defined therein for communication with the oil holes, the ports being connected to the working oil tank and the hydraulic cylinder unit. The power steering device also includes a steering shaft for operating the rotary valve mechanism in response to a steering action. The hydraulic cylinder unit, the rotary valve mechanism, and the steering shaft are integrally joined to each other.

The present invention relates to a bulky sheet 10 having a fiber aggregate 11 formed by hydroentanglement of fiber webs 11a and 11b. The fiber aggregate 11 has a first region 21 having a high fiber density and a small thickness and second regions 22 having a lower fiber density and a larger thickness than the first region 21. The second regions 22 are each defined by a closed figure defined by the first region 21. The second regions 22 each have protrusions 31 and depressions 32.
摘要:
A method of assembling a magnetic tape cartridge where an opening, through which a magnetic tape is drawn out, is provided in part of a sidewall of a cartridge case across a lower half and an upper half of the cartridge case. A slide door that opens and closes the opening is mounted between guide portions provided in the cartridge lower and upper halves, while stressing the slide door with a spring member toward a position in which the opening is closed. During mounting, the slide door is stressed with the spring member toward the position in which the opening is closed by fitting a lower edge of the slide door into the guide portion of the lower half A mounting position of the slide door is retained by holding an end of the slide door facing a direction in which the slide door moves to close the opening.

An indwelling catheter is made of a polyurethane resin having a Shore hardness of 60D or more. The soft segment of the polyurethane resin is constituted by polycaprolactone. The indwelling catheter has a kinking resistance of 10 mm or more when measured at 37.degree. C. in wet state. The Young's modulus is at first 20 kgf/mm.sup.2 or more when measure at 25.degree. C. in dry state, and reduces to 15 kgf/mm.sup.2 or less by soaking it in water of 37.degree. C. for 5 minutes or less.

摘要:
This invention provides a medical device in which its lubricity is continually maintained and its safety is guaranteed.Particularly, it provides a medical device in which lubricity is generated on at least a portion of its surface when the device is contacted with body fluids or exposed to physiological aqueous conditions, wherein the lubricity-generating portion is formed by thermoforming.
摘要:
A ceramic electrostatic chuck with a built-in heater having electrodes of an electroconductive ceramic bonded to a surface of a supporting substrate of an electrically conducting ceramic. A heat generating layer of an electroconductive ceramic is bonded to the other surface of the supporting substrate and a covering layer of an electrically insulating ceramic is provided thereon. Each of the supporting substrate, electrode for the electrostatic chuck and heat generating layer has a surface roughness Rmax of 5 .mu.m or larger.

A plasma etching apparatus for a semiconductor wafer includes a susceptor arranged in a vacuum process chamber. A groove for flowing a heat transfer gas is formed in the mounting surface of the susceptor. The groove includes an annular groove portion formed along the peripheral edge of the mounting surface, and a gas path vertically extending through the susceptor is connected to the annular groove portion. A sheet-like electrostatic chuck is airtightly adhered to the mounting surface of the susceptor to cover the groove. A plurality of through holes are formed in the electrostatic chuck, and these holes are arranged along an above the groove. The heat transfer gas is supplied between the electrostatic chuck and the semiconductor wafer through the gas path, the groove, and the through holes. The heat transfer gas contributes to transfer of cold from a liquid nitrogen source arranged under the susceptor to the wafer.
摘要:
A device and method for inducing sleep, improving blood circulation, and correcting autonomous imbalances. The device includes a heat exchange member mounted on top of housing, the heat exchange member can receive a neck of a user and apply alternate hot and cold stimuli to the neck. The hot and cold stimuli improve blood circulation and correct the autonomous imbalances. The device includes a drive module and a heat sink to quickly switch from hot to cold.
