A magnetic head includes a main pole, a write shield, and a gap part. The write shield includes first and second side shields and a top shield. The main pole has first and second side parts. The first side shield has a first sidewall. The second side shield has a second sidewall. The gap part includes a gap film and a nonmagnetic layer. The gap film is disposed to be in contact with the first and second sidewalls. The first side part has first and third side surfaces arranged in this order from the medium facing surface side. The second side part has second and fourth side surfaces arranged in this order from the medium facing surface side. The nonmagnetic layer is present between the third side surface and the first sidewall and between the fourth side surface and the second sidewall.

A container comprising a frame conforming to ISO intermodal container dimensions, a hopper attached within the frame; the hopper defining a chute having a first opening and a second opening, at least one door pivotally attached to the hopper proximal to the second opening; at least one gate assembly attached to the at least one door; a connector apparatus panel mounted to the frame; and at least one actuating fluid or electrical line connected between the at least one gate and the connector apparatus panel. An alternative embodiment includes at least one air tank connected to the container and filled through an air transfer system and a plunger system to cause actuation of container doors for releasing of materials into a second receptacle and where the air transfer and plunger systems reside partially on a rough terrain container handler vehicle.

A terminal identification method is provided which enables two-way communications between terminals and a network while identifying terminal IDs and protecting privacy. Also, authentication method and system are provided which require no complicated calculating process, less steps and smaller amount for wireless communications, and less power consumption. A server and terminal share a hash function and an initial value determined for each terminal, calculate the same temporary ID by hashing the initial value the same number of times with the hash function, and identify the terminal using the calculated temporary ID. The server and the terminal also hold a common hash function and authentication information, acquire an authenticating communication parameter from communication parameters temporarily common during communication, and generate an authentication key using the authentication information, the authenticating communication parameter, and the hash function. Then at least one of the server and terminal performs authentication using the generated authentication key.

A magnetic head includes a main magnetic pole, a shield having an end face located in a medium facing surface to wrap around an end face of the main magnetic pole, and a gap part provided between the main magnetic pole and the shield. The shield includes a bottom shield, two side shields, and a top shield. The gap part includes first and second gap layers. In a manufacturing method of the magnetic head, a mold is formed on the top surface of the bottom shield, the mold having a shape determined by photolithography and being intended to be removed later. Next, the two side shields are formed on the top surface of the bottom shield by performing plating without forming a seed layer. Next, the mold is removed and then the first gap layer, the main magnetic pole, the second gap layer, and the top shield are formed in succession.

The invention discloses a safety authentication method for hiding an ultrahigh-frequency electronic tag identifier (TID). According to the safety authentication method, the TID is encrypted by using a random number, and is returned in the form of ciphertext, so that an illegal reading-writing device can be effectively prevented from acquiring TID information and performing illegal tracking and identification on an object marked by an electronic tag. Meanwhile, through the authentication method, attacks such as wiretapping, counterfeiting and replaying can be effectively resisted; and the method has the advantages of preventing electronic tag information from being stolen, preventing tag counterfeiting and the like. According to the safety authentication method, a domestic symmetric encryption algorithm is adopted, and double-key and secondary authentication mechanisms are adopted, so that electronic tag validation of batch cards and keys and bilateral safety verification of a single tag and a single key are realized.

This invention discloses a communication method for MIPv6 mobile nodes including: a mobile node accesses network at the access place and gets a new delivery address to be used to compute PID, and the mobile node uses the PID instead of its hometown address and binds it with the delivery address as the updated messages to be sent to the hometown proxy and communication nodes, which utilizes the PID to resume the hometown address of the mobile node.

The present invention is directed toward a method and system for tracking webpage requests from web browsers without invading the privacy of the corresponding users. A server receives the webpage requests, and extracts from each of them a user-neutral identifier and URL. The server creates records of these webpage requests, and these records are used to create and update profiles for the corresponding user-neutral identifiers. Since the user-neutral identifiers are not tied to user-specific information, the profiles are made anonymous and user privacy can be protected. However, since each user-neutral identifier is tied to a particular web browser, useful information regarding individual browsing behavior can be obtained. Furthermore, the requested URL's can be categorized before being used to update the profiles, thus eliminating concerns that a user's browsing activity might be tracked from website to website.

A vacuum suction apparatus is equipped with a body having a supply port, and a pad provided on a lower portion of the body to which a workpiece can be attracted under suction. The pad is constituted from a base plate accommodated in a space of the body, a flexible intermediate plate provided on a lower portion of the base plate, and a suction sheet body disposed on a lower portion of the intermediate plate and having a sheet that attracts the workpiece under suction. In addition, the base plate, the intermediate plate and the suction sheet body are stacked along an axial direction of the body. The rigidity of the base plate is highest, whereas the rigidities of the intermediate plate and the suction sheet body are lower in this order, and the flexibilities thereof are greater in this order from the base plate.
