An information processing unit and a method for making the same with a cooling structure for a heat generating element, for example a CPU, which can efficiently cool the CPU without losing flexibility of a board level packaging. The information processing apparatus includes a cooling unit cooling the heat generating element, an airflow supply unit supplying airflow to a part of the cooling unit, an airflow control unit controlling airflow applied to the airflow supply unit, an inlet, and an outlet. The airflow supply unit, the airflow control unit, and the part of the cooling unit are linearly arranged. The inlet is located to draw air towards the airflow control unit and the exhaust is located to exhaust air from the part of the cooling unit.

There is provided a method for lining the internal surface of a pipe having a first open end and a second open end. Said method comprises the steps of introducing a predetermined amount of a resin into the pipe through the first open end thereof, causing the introduced resin to move through the pipe toward the second open end thereof, so as to form a resin lining layer on the internal surface of the pipe, blowing into the pipe a predetermined amount of flake material and causing the flake material to adhere to the surface of the resin lining layer in the pipe, inserting into the pipe a ball-like pig having a predetermined diameter such that an even resin lining layer having a desired uniform thickness may be formed on the internal surface of the pipe, and causing the inserted ball-like pig to move through the pipe along the entire length thereof, thereby embeding the above flake material into the resin lining layer, and forming on the pipe internal surface an even resin lining layer having a desired uniform thickness.

A method of repairing an existing pipe includes steps of introducing at least one leading pig into the existing pipe through one open end thereof, introducing behind the leading pig a necessary amount of adhesive agent into the existing pipe through the same open end thereof, fixing one end of a liner tube at the above open end of the existing pipe, in a manner such that the liner tube may be reversed into the existing pipe, and providing a negative pressure into the existing pipe through an opposite open end thereof to cause the leading pig and the adhesive agent to move forwardly and thus cause the unfixed portions of the liner tube to be reversed into the existing pipe. The adhesive agent is caused to move through the existing pipe in the form of a plug flow, thereby coating the whole internal surface of the existing pipe with the adhesive agent, ensuring that the liner tube reversed into the pipe may adhere to the internal surface of the existing pipe.

There is provided a method of lining an existing underground main pipe involving a branch pipe. The method comprises injecting a necessary amount of resin into the branch pipe from an open end thereof, introducing behind the resin a pig apparatus into the branch pipe, applying a positive pressure behind the resin and pig apparatus in the branch pipe to cause the resin and pig apparatus to move forward until the entire internal surface of the branch pipe is lined with the resin by means of the pig apparatus and until the pig apparatus reaches and slightly passes beyond a branching position where the branch pipe is branching from the main pipe, applying a negative pressure behind the pig apparatus in the branch pipe to cause the pig apparatus to stop at the branching position such that the branch pipe is completely isolated from the main pipe, injecting a necessary amount of resin into the main pipe from an open end thereof, inserting behind the resin a lining pig into the main pipe, applying a positive pressure behind the resin and lining pig in the main pipe to cause the resin and lining pig to move through the main pipe along the entire length thereof, so as to form a resin lining layer on the internal surface of the main pipe.
摘要:
An amount of resin necessary for lining an inner surface of a pipe is calculated. A lining pig is inserted in the pipe from an open end thereof, and the calculated amount of resin is supplied in the pipe from the open end subsequent to the insertion of the lining pig. A blocking pig is inserted in the pipe behind the resin, and a pressurized non-compressible liquid is supplied in the pipe subsequent to the insertion of the blocking pig thereby feeding the charged resin through the blocking pig until a front end of the resin reaches an inner end of the pipe. The resin is sucked together with the lining pig and the blocking pig so that the inner surface of the pipe is lined with the resin.
摘要:
Methods of lining the internal surface of a pipe, include first inserting two lining pigs into the pipe and then introducing a batch of resin thereinto, or inserting one lining pig between two batches of a resin, or first inserting a lining pig and then inserting two batches of a resin with another lining pig therebetween, or first introducing a lining pig made of a soft material capable of deforming so as to pass through a narrow-passing section and then introducing a batch of a resin into the pipe, causing the resin to move forward until the front end of the resin reaches an inner end of the pipe, and sucking the resin back from the inner end so as to line the internal surface of the pipe with the resin. The methods use improved liquid blocking pigs for use in pipe lining treatment, each of such pigs includes a spherical body made of a soft resilient material and at least one flexible liquid barrier diaphragm interposed in the spherical body.
