摘要:
A closed type scroll compressor has a drive shaft supported by a frame through bearings lubricated with a lubricating oil supplied from an oil reservoir via a lubricating oil passage bore formed in the drive shaft. The end of the drive shaft in which the upstream end of the lubricating oil passage bore opens is connected to the oil reservoir through a joint tube which is supported by supporting structures including a combination of a spherical slide bearing and slide bearing and capable of taking up any mounting error or displacement of the drive shaft in any direction. The compressor can be assembled easily without any risk of uneven or local contact of each sliding portion.
摘要:
A hermetic scroll compressor comprising a compressor component and an electric motor arranged respectively in upper and lower portions of a closed housing. The compressor component includes fixed and orbiting scrolls in mesh with each other. A frame is fixedly connected to the fixed scroll and supports the orbiting scroll for orbiting motion, with at least one passage group of a plurality of vertically extending passages being provided at a peripheral surface of the frame for communicating a space above the compressor component with a space between the compressor component and the electric motor. One of th e passages has a higher fluid resistance than the remaining passages, with the passage having high fluid resistance being vertically aligned with a passage provided at the periphery of the electric motor for communicating the space above the electric motor with a lubricating oil reservoir below the electric motor. A discharge pipe communicating with the outside of the closed housing is connected thereto at a location remote from the passage group as viewed in a rotational direction of a rotor of the electric motor.
摘要:
A multiphase solid-state contactor for controlling a principal circuit, comprising a plurality of thyristors connected in anti-parallel relation, and an electronic control circuit connected to the thyristors including a firing control circuit, an input circuit and a surge absorbing circuit. The input circuit may include a rectifier and voltage detector for compensating for variations in the operating voltage of the principal circuit. Each of the firing control circuit, the input circuit and the surge absorbing circuit may comprise separate printed circuit boards which may be mounted in stacked relation in a casing for ease of handling and repair. Auxiliary terminals are also provided for outputting an auxiliary output signal from the device.

An object of the present invention is to provide a drug and a method for effectively inducing donor-specific immune tolerance in a recipient in transplantation therapy. A complex of an siRNA for a costimulatory factor and schizophyllan is delivered to a Dectin-1 expressing cell which specifically recognizes schizophyllan to regulate the function of the Dectin-1 expressing cell, and therefore can induce immunosuppression effect as well as induce immune tolerance effectively.

A scroll compressor is constructed by combining a stationary scroll and an orbiting scroll formed by erecting a scroll-shape wrap upright on a base plate meshing with each other. A scroll member constructing the stationary scroll or the orbiting scroll is constructed of an inner layer member 601 forming a core metal and an outer layer member 600 arranged so as to surround the inner layer member and forming an outer layer part, the inner layer member is constructed of a material with higher modulus of elasticity than that of the outer layer member, and separation prevention parts (uneven parts 603, depressions 604, or holes 605) preventing the inner layer member and the outer layer member from separating with each other due to difference in coefficient of thermal expansion thereof are arranged in the inner layer member.

摘要:
Disclosed is a new type of immunostimulating agent including an immunostimulating oligonucleotide complexed with a carrier which is safe and has a high transfection effect. The carrier complexed with the immunostimulating oligonucleotide to form the immunostimulating agent is a polysaccharide having β-1,3-bonds (preferably β-1,3-glucan such as schizophyllan). A preferred example of the immunostimulating oligonucleotide is one containing an unmethylated CpG motif. The polysaccharide for use is preferably modified with nucleic acid-binding functional group and/or cell membrane-affinitive functional group.

This invention discloses a method and apparatus where a pre-treatment which reduce interfacial level density is carried out before thin film deposition on a substrate utilizing a catalytic gas phase reaction. The catalytic gas phase reaction is generated with a treatment gas which is supplied with the substrate via a thermal catalysis body provided near the substrate surface. Thin film deposition on the substrate surface is carried out after this pre-treatment. The thermal catalysis body is made of tungsten, molybdenum, tantalum, titanium or vanadium, and is heated by a heater. And, this invention also discloses a semiconductor device having a semiconductor-insulator junction with its interfacial level density is 10.sup.12 eV .sup.-1 cm.sup.-2 or less, which is brought by the above pre-treatment in the insulator film deposition process.
摘要:
An oil feeding system for a scroll compressor includes an enclosed vessel accommodating therein an electric motor disposed at an upper position and a scroll compressor section disposed at a lower section and adjacent to the motor. A suction pipe opens into the enclosed vessel for the purpose of maintaining a low-pressure atmosphere in the interior of the enclosed vessel. A gyratory shaft of a gyratory scroll engages with an eccentric hole formed in the end of the drive shaft, and a trochoid pump is disposed at the end of the gyratory shaft. A pump case has a portion below the pump, which is formed with a circular-arc large-volume suction port on one side thereof and a circular-arc discharge-side oil sump on the other side thereof. The suction port communicates via an oil line with an oil reservoir provided at the bottom of the enclosed vessel and the circular-arc oil sump communicates with the trochoid pump whereby oil discharged by the trochoid pump is fed to various portions to be lubricated through cavities of the eccentric hole.
