A content distribution system. A distribution management and unauthorized operation management device generates a one-time URL by using URL of content information specified by a user terminal and transmits the one-time URL and bandwidth information concerning the content information to the user terminal. A session control server extracts the one-time URL from a session control message transmitted from the user terminal, transmits it to the distribution management and unauthorized operation management device, and establishes a session between the content distribution server and the user terminal according to an authentication result performed by using the one-time URL transmitted from the distribution management and unauthorized operation management device and a correlation result obtained by correlating the bandwidth information contained in the session control message transmitted from the user terminal with the bandwidth information transmitted together with the authentication result from the distribution management and unauthorized operation management device.
摘要:
It is possible to provide a video audio stream distribution system, a distribution method, and a distribution program which can improve the stream switching speed during zapping and suppress the actually used network resource in streaming for which QoS is guaranteed. Zapping destination means (211) predicts a stream required for the next distribution request and band managing means (209) instructs only band allocation for the predicted stream to band control means (205) before a distribution request is made by an actual zapping operation.

A CPU contained in an information processing apparatus in accordance an exemplary embodiment of the present invention outputs an access request including first access destination address information by a first program, and outputs a check request including second access destination address information when the execution program is switched from the first program to a second program as a result of a program call from the first program to the second program. A protection setting check portion contained in the information processing apparatus checks whether or not the check request including the second access destination address information conforms to protection setting for the first program based on memory protection information that is established in a memory protection information storage portion to detect a violation by a memory access request by the first program.

Disclosed are a method of producing a crystalline semiconductor material capable of improving the crystallinity and a method of fabricating a semiconductor device using the crystalline semiconductor material. An amorphous film is uniformly irradiated with a pulse laser beam (energy beam) emitted from an XeCl excimer laser by 150 times so as to heat the amorphous film at such a temperature as to partially melt crystal grains having the {100} orientations with respect to the vertical direction of a substrate and melt amorphous film or crystal grains having face orientations other than the {100} orientations. Silicon crystals having the {100} orientations newly occur between a silicon oxide film and liquid-phase silicon and are bonded to each other at random, to newly form crystal grains having the {100} orientations. Such a crystal grain creation step is repeated, to form a crystalline film which has crystal grains preferentially grown in the {100} orientations with respect to the vertical direction of the substrate and thereby has sharp square-shaped crystal grain boundaries.

According to one embodiment, a plug includes four terminals arranged around a core shaft at substantially equal intervals, a housing that supports proximal ends of the four terminals, and a cylindrical cover fixed to the housing such as to surround the four terminals. The four terminals include two power terminals and two ground terminals, and at least the two power terminals have insulating coating layers respectively at their distal end portions.

A vacuum chamber includes a plasma generating space in its interior. A magnetic field generating device applies a fluctuating magnetic field to the plasma generating space to cause plasma therein to fluctuate. A substrate is placed in the plasma generating space so that when a potential difference is evoked between a first conductor and a second conductor as a result of the fluctuation of the plasma, the potential difference causes nanoholes to be formed in the substrate.

摘要:
An air cooled oil cooler has an upper plate, a lower plate and a plurality of tubes and outer fins disposed therebetween. Each tube contains an inner offset fin, and the outer fins formed in a corrugated shape and each having one return louver on an intermediate portion between a top portion and a bottom portion of the outer fin. The outer fins is disposed between the tubes so that the tubes and the outer fins are arranged alternatively and stacked in a pile between the upper and lower plates. The tubes are formed to be flat tubes having a height-width ratio of the tube to be 4.8-7.4%.

A switchgear has an insulating container filled with an insulating gas, a fixed current-carrying shaft fixed airtightly to one opening of the insulating container, a fixed contact provided on an end of the fixed current-carrying shaft in the insulating container, a movable contact configured to separably contact the fixed contact, a movable current-carrying shaft having the movable contact provided on an end and airtightly movably penetrating the other opening of the insulating container, and an operation mechanism coupled with the movable current-carrying shaft at an outside of the insulating container. The insulating container is constituted by a plurality of insulating layers, and the insulating layers are higher in dielectric constant as closer to an inside of the insulating container.
