摘要:
A call process processor (CC) outputs a control instruction of a connection only to a line response unit at a source side. The line response unit at the source side transmits a connection control cell where a VPI/VCI corresponding to a specified connection is set, tag information indicating a route to a line response unit at a destination side is set, connection control information identifying it as the connection control cell is set in an empty area of the header and connection information for controlling the specified connection is stored, to an ATM switch. The line response unit at the destination side extracts the connection control cell which is transmitted from the line response unit at the source side and input from the ATM switch according to the connection control information, and controls the specified connection according to the extracted connection control cell.

A congestion control system appropriately controls congestion of cells independently of the configuration of source and destination terminal units in, for example, an ATM switching unit, and shortens the time taken from the generation of congestion to the start of control. A buffer for switching the cells in a switch device adds to the cells transmitted through the switch device an EFCI for use in notifying the destination terminal unit of the congestion state of the cells. An output line device detects together with a VPI/VCI the EFCI added to the cell to be output from the switch device to the destination terminal unit. The output line device transmits to the switch device the VPI/VCI corresponding to the detected EFCI and an RM cell in which backward congestion indication is set.

Disclosed is a single plate projection type display apparatus which is capable of achieving a high luminance without an increase in an output of a light source. A first lens plate having a plurality of lenses divides a light from a light source into a plurality of light beams. A second lens plate having a plurality of lenses superposes the divided plurality of light beams on a light valve, thereby performing an illumination. A color separation optical system composed of dichroic mirrors which are perpendicular to an XY plane and form predetermined angles to each other, performs a color separation for the light beams from the second lens plate. The light valve modulates R, G and B light beams which are incident thereonto. The modulated lights are projected by a projection lens. The whole shape of the second lens plate is a rectangle. The second lens plate is disposed so that a longitudinal direction of the longer side of the whole shape of the rectangle is perpendicular to a plane formed by a normal line to the dichroic mirrors and an optical axis immediately before an incidence onto the dichroic mirrors.

A display device for displaying an image has a light source; an image forming element array for forming images of irradiation light beams emitted from the light source; a display panel including two-dimensionally arrayed pixels defined as a unit for controlling an intensity of transmitted light beams; image displaying section which the transmitted light beams with the irradiation light beam intensity controlled; and a light distributing section for splitting and distributing the irradiation light beams to said image forming element array, disposed between the light source and the image forming element array. The light distributing section is realized by either one of a lens array consisting of a plurality of lenses, which splits the irradiation light beams according to the plurality of lenses and converges the split light beams or an ellipse mirror constructed of two or more different rotary elliptical surfaces. This display device can be applied to a projection type display device by adding a projecting section which projects the light beams emerging from the display panel upon a screen or a pupil.

A route is selected such that a cell pass through the SRM at the second stage that has the smallest free band when the call requested by the subscriber is to be processed for the point-to-point connection, thereby exercising control such that routes having larger band are reserved. A route is selected such that a cell pass through the SRM at the second stage that has the largest free band when the call requested by the subscriber is to be processed for the multicasting connection, thereby exercising control to avoid contentions between the route selected for the multicasting connection and the route selected for the point-to-point connection.
摘要:
The present invention provides culture methods of T lineage precursor cells comprising a step of culturing the T lineage precursor cells under a condition that a dissolved oxygen concentration in the nutrient medium is higher than a dissolved oxygen concentration in the nutrient medium when the medium is in contact with normal atmospheric air. According to the methods of the present invention, by using a submerged (suspension) culture which is a general method for culturing cells or tissues, the derivation of matured T cell(s) differentiated from T precursor cells in terms of their phenotypes of differentiation antigens and of their functions is realized to be accomplished.

An apparatus comprises a print section for printing a face image and characters on a first card medium, a check section for checking on whether the first card medium is defective or not, an integration section for integrating the first card medium with a second card medium with an IC memory to produce a certificate card only when the print of the first card medium is acceptable, and a write section for writing at least the data corresponding to the face image and characters into the memory section of the second card medium. The apparatus further comprises an automatic reception section containing a retina image photoing unit and an eyesight test unit, wherein an retina image of the owner of the card is photoed, while he or she is having an eyesight tested, thereby identifying the owner.
摘要:
In an air conditioning device having an air passage device that extends inside an instrument panel in a lateral direction of the body of a motor vehicle, the air passage device has a substantially L-shaped slit for attachment and detachment of an air filter, the slit being formed of a first slit opening downwardly and a second slit opening rearwardly of the vehicle body and a gap is provided between the second slit and a front end portion of a glove box. This permits the air filter of a square plate shape to be attached to and detached from the slit without interfering with the glove box, while being rotated slightly along the floor and toe board of the passenger compartment.
