摘要:
A fluid compressor has a cylinder (17), a rotary rod (21), and a helical blade (33) that defines work chambers (44) between the cylinder and the rod. The compressor successively compresses and conveys a fluid from a suction end to a discharge end through the work chambers according to the rotation of the rod. The continuous helical blade is formed by pressurizing and injecting synthetic resin material such as tetrafluoroethylene-perfluoroalkylvinylether polymer resin into a mold through two gates (39), so that a weld line (43) of the blade is located in an intermediate region between a suction pressure region and a discharge pressure region of the blade.

The edit unit is configured to execute the edit process, which is accepted by the accept unit, on the image read by the scanner. The storage is configured to store the image edited by the edit unit.
摘要:
When a packet data is transmitted, a sync pattern comprising ‘q’ words (‘q’=m+n) is added to the data. The ‘q’ words is formed by combining a fixed pattern comprising ‘m’ words (‘m’ is an integer greater than 0) with plural types of variable patterns each comprising ‘n’ words (‘n’ is an integer greater than 1). In this case, a bit structure included in at least two consecutive packets should include different types of variable patterns.

A fluid compressor comprising a helical blade type compression mechanism that includes a cylinder, a roller arranged inside the cylinder and a helical blade interposed between the roller and the cylinder. The blade, the roller and the cylinder are formed of materials whose coefficients of thermal expansion satisfy relationships: Blade>Roller>Cylinder. According to this invention, pressure release can be easily performed in the case where the liquid flows back or under a low-temperature condition as at the time of actuation. In addition, the compression performance can be improved under a high-temperature condition during operation.

A fluid machinery is disclosed which is able to assure a large compression volume without an increase in size and achieve high compressibility by suppressing leakage from sealing, thereby improving the reliability. In the fluid machinery, a second spiral 13 having a spiral inner engaging surface 17 formed to have a stepped shape in section is engaged with a first spiral 15 having an outer engaging surface 21 with a stepped sectional shape which rises upwardly from an outer peripheral side to a central side in a spiral manner, so that sealed spaces 25 are formed to cause reduction in volume of sealed spaces in both radial and height directions from a peripheral side to a central side. A closed spaces 35 having an inclination surface 19 is formed between a stepped surface of the outer engaging surface 21 of the first spiral 15 and a stepped surface of the inner engaging surface 17 of the second spiral 13. A spiral member 37 having a slant surface 39 which engages always with the inclination surfaces 19 is provided in the sealed spaces 35 so as to seal the lower pressure sealed spaces 25 and the higher pressure sealed spaces 25.

The present invention provides a resin molding method for fuel cell separator. The fuel cell separator includes: a resin mold region formed inward a predetermined distance from an edge; a through hole formed at the resin mold region; and a front end region formed between the through hole and the edge at the resin mold region. The resin molding method includes: a die set process that the resin mold region of the fuel cell separator is set in the die such that the front end region is held by a pair of anti-deformation pins of the die; and a resin filling process that a resin is filled in the die, wherein the resin is molded on the resin mold region of the fuel cell separator so as to be filled in the through hole, and a resin member is thereby molded on the resin mold region so as to extend outward from the edge.

A gas-insulated switching apparatus is disclosed which includes a circuit breaker having a breaking section with at least a couple of mutually detachable contacts and a grounded tank containing the breaking section and filled with an insulating gas, the grounded tank being maintained at earth potential. A first bushing is vertically mounted on one side of the grounded tank, the central conductor of the first bushing being connected with one of the contact of the breaking section. A disconnecting switch has insulating gas sealed in it and accommodates a disconnecting section in a tank which is arranged connected to but gas-partitioned from the circuit breaker in an axially extending region of the grounded tank on the other side of the region where the first bushing is mounted. A bushing support tank has insulating gas sealed in it and is arranged so that is connected to but gas-partitioned from the disconnecting switch in an axially extending region of the grounded tank on the side of the disconnecting switch which is opposite to that of the circuit breaker. A second bushing is vertically mounted on the bushing support tank and a grounded switch is arranged inside the bushing support tank in a region which is an axially extending region of the circuit breaker. A lightning arrester is arranged gas-partitioned from the bushing support tank below the axis of the circuit breaker and the disconnecting switch but in the direction of this axis. The lightning arrester is electrically connected to the central conductor of the second bushing inside the bushing support tank.
摘要:
Construction of a rolling bearing with seal ring can be achieved in which, while securing the required seal performance, the rotation support portion can be made more compact by shortening the dimension in the axial direction of the installation space for an inner ring 3a, and torque can be lowered. A sliding contact edge 23 of a seal lip 12a that is provided around the inner-circumferential edge portion of a seal ring 5a on one end side in the axial direction comes in sliding contact with one end surface 24 of the inner ring 3a. The tip-end edge of a protruding portion 20 closely faces the surface of the inner ring 3a, forming a labyrinth seal 19 in this portion. With this construction, a stopper ring 17 for regulating the position in the axial direction of the inner ring 3a with respect to a shaft 15 is located so as not to protrude from the end surface in the axial direction of the rolling bearing 1a with seal ring. The problem can be solved because the diameter of the sliding contact portion is kept small.
