摘要:
A variable displacement compressor including a drive shaft through which a gas passage extends between front and rear ends of the drive shaft. The gas passage is connected to a suction chamber at the rear end of the drive shaft. The drive shaft includes a first gas inlet passage, which connects the gas passage to a crank chamber through a lip seal, an oil chamber, and a thrust bearing, and a second gas inlet passage, which connects the gas passage to a central portion of the crank chamber. The drive shaft further includes a sleeve movable along the drive shaft as a swash plate inclines to adjust an open amount of the second gas inlet passage in accordance with the inclination angle of the swash plate, that is, the displacement of the compressor.

A load determining section of a drive control apparatus for forklift determines a load state related to a loading attachment. In a case where a connection determining section determines switching to a connection state, if the load state determined by the load determining section requires that driving of a vehicle body be limited, a disconnection control section forcibly disconnects a transmission of a driving force to a drive wheel. Thus, the forklift is prevented from being started in a state that is likely to make the driving of the forklift unstable.

The present invention provides techniques for spatial reuse in wireless communications networks. Accordingly, the present invention provides A device participates in a wireless communications network. The network has a shared transmission medium for the exchange of communications traffic. Further, the device determines a value for at least one interference condition in the shared transmission medium of the wireless communications network. Based on this value, a planned transmission to a remote wireless communications device is scheduled. For instance, when this value is less than a predetermined threshold, this scheduling employs a time-overlapping access technique.

This invention provides an image capturing apparatus which sets the spectral characteristics of a split light beam to be substantially equal to those of straight traveling light upon splitting a light beam coming from a photographing optical system and enables an autofocus detection function by the split light with a sufficient light amount. A digital camera includes a photographing optical system, beam splitter, focus detection sensor, polarizing filter, and CMOS sensor. The beam splitter splits a light beam which travels toward the CMOS sensor that receives an object image formed by the photographing optical system, depending on the direction of polarization, and the focus detection sensor performs focus detection based on the light beam split by the beam splitter. The polarizing filter removes substantially the same polarized light component as a polarized light component that travels toward the focus detection sensor as a result of splitting by the beam splitter.

Event driven methods for implementing or removing a filter used in receiving a multicast transmission are disclosed. An exemplary method for implementing a filter includes: detecting a message, such as an IPv6 MLD message, wherein the message comprises an address of a multicast group and a request to join the multicast group to receive a multicast transmission; in response to detecting the message, determining a filter parameter (e.g., a PID number and/or MAC address) needed to receive the multicast transmission; and implementing the filter parameter to receive the multicast transmission. Alternative methods wherein filter implementation or removal is based on the detection of direct procedure calls, such as a Setsockopt call, are also disclosed.

A projection optical system having a multilayered film mirror arranged to provide an approximately uniform reflectance throughout a predetermined light incidence angle range to thereby assure a desired optical performance. A projection exposure apparatus having such a projection optical system, and a device manufacturing method using such an exposure apparatus. A non-periodic film is used in a reflection multilayered film upon a mirror having a largest light incidence angle range or a mirror having a largest average of light incidence angle, and this effectively reduces a pupil transmittance distribution in the projection optical system.

Provided are a data processing apparatus and method that make it possible to detect improper resource data that has been stored in a printer. The data processing apparatus, which is connectable to an image forming apparatus that refers to resource data when an image is formed, first acquires information relating to resource data that has been stored in the image forming apparatus and stores the information on a hard disk. Next, improper resource data is detected by control exercised by a CPU in the processing apparatus based upon the acquired information relating to the resource data. After prescribed processing is executed with respect to improper resource data that has been detected, information relating to prescribed resource data is provided to the image forming apparatus via a network controller.
