Abstract: A magnetic head including an upper pole and a lower pole for generating a leakage magnetic flux to magnetize a recording medium to have a predetermined pattern, wherein the upper pole has a structure in which the central portion of a side opposite to the recording medium is thicker than the edges of the side. In this magnetic head, the upper pole has a shape in which its central portion protrudes higher than its edges. Thus, the shape of a magnetic field distributed can be maintained rectangular even if the width of the upper pole is reduced, which enables an increase in the track density of a recording medium.

Abstract: A simplified matchmaker matches users of a computer network, such as the Internet, based on the number of games the users have abandoned. A one-action input is received at a requesting client application executing on a computer connected to the computer network. Next, information that is stored within the computer is collected. The information is stored within the computer using a process that is unrelated to and separate from the one-action input received from the user. Then, at least one message is sent from the requesting client application to a host computer connected to the computer network containing information relating to a request for initiating a matchmaking process on the host computer that matches requesting user into an online interactive session along with other suitable users, such that each suitable user is connected to the computer network through a client application compatible with the requesting client application.

Abstract: Disclosed in an inert gas generator to produce a large quantity of inert gas within a short period of time. The inert gas generator comprises: a gas turbine consisting of a starter motor, compressor, combustor and turbine body; an afterburner being connected to an exit of the gas turbine to re-burn gas burned in the combustor and being equipped with a flame stabilizer; a cooling chamber being equipped with spray nozzles to eject water to decrease gas temperature in the afterburner exit; an evaporator set to further cool the gas-steam mixture from the afterburner; a cooling chamber and spray nozzles; an exhaust nozzle to guide the direction of the inert gas-steam mixture of low temperature and oxygen content; and a controller for controlling the starter motor, the fuel pump and combustor. The inert gas generator mounted on a movable vehicle can promptly suppress the fire occurred in various places with least amount cost possible.

Abstract: A method and system for determining network latency between clients in a computer network, such as in a gaming zone environment. Each client determines the network latency between each other client via a ping, response, and response-response protocol. To this end, a first client places first time information such as a timestamp into a (ping) data packet and sends the packet to the second client, who places second time information into the packet, and sends the packet as a response packet back to the first client. The first client determines a first network latency based on its current time and the first time information returned in the response packet. The first client then sends the packet back to the second client as a response to the response packet. The second client determines a second latency based on the current time information at the second client and the second time information received in the response-response packet.
