A portable personal server connectable through a network with a PC connected with an external network that permits communication with the PC only when user's fingerprint information read out by means of a fingerprint authentication unit matches registered information. In order to communicate through the network, the portable personal server and the PC acquires an address, preferably using APIPA, so that the collision of address does not take place in the external network. Consequently, the portable personal server also functions as a network server on the external network. A portable personal server exhibiting high confidentiality of data and suitable for central management of data can thereby be realized.
摘要:
The communication terminal of a communication system comprises a virtual network switch which can forcibly alter the destination of data being transmitted/received between the communication terminal and a network. Data is transmitted/received between the network and the communication terminal through a portable electronic device. Various functions, including a security function, can be supplemented by providing the function in software mounted on the portable electronic device. Even if a communication terminal connected directly with the network is not provided with such functions as a VPN, firewall or virus check, high-safety communication is ensured utilizing these security ensuring means mounted on the portable electronic device.

A sewing machine frame having a reinforced structure providing a bed, a tower upstanding from the bed and an arm extending from the tower at a position above the bed. The frame is made from a synthetic resin and includes a main frame body and a frame cover attached to the main frame body. The main frame body includes a back panel wall having a first peripheral edge, and a first side wall integrally protruding from the first peripheral edge. The frame cover includes a front panel wall having a second peripheral edge, and a second side wall integrally protruding from the second peripheral edge. The main frame body and the frame cover are coupled by means for couplings formed near the first and second side walls.

a sewing machine frame for a sewing machine including an integral frame member, and reinforcing ribs. The integral frame member is made from a synthetic resin and provides an outer surface defining an external shape and an inner surface providing an internal space. The integral frame member includes a bed portion, a tower portion upstanding from the bed portion, and an arm portion extending from the tower portion in a cantilevered fashion. The reinforcing ribs are provided at substantially entire area of the inner surface for reinforcing the integral frame member.

The invention has its object to provide a swash plate compressor capable of realizing demonstration of an excellent sliding characteristic when a drive shaft is rotated at high speed, and of a high refrigerating capacity when the drive shaft is rotated at low speed.With the swash plate compressor of the invention, an oil guide groove, an oil guide hole, a first hole, an outflow hole, a valve hole, a communication port, a receiving chamber, a throttle hole, and a second hole constitute a release passage. The oil guide groove, the oil guide hole, the first hole, the outflow hole, the valve hole, the communication port, the receiving chamber, and the throttle hole constitute a first passage. Also, the second hole constitute a second passage. A valve mechanism increases a ratio, at which the first passage occupies the release passage, as a drive shaft is increased in rotating speed.
摘要:
A sewing machine frame having reinforced structure for use in a sewing machine is disclosed. The sewing machine frame has a frame member formed of a synthetic resin and having a bed portion, a tower portion upstanding from the bed portion, and an arm portion extending from the tower portion at a position above the bed portion, the bed portion, the tower portion and the arm portion being formed integrally and providing a concaved peripheral wall defining a stitch working space. The sewing machine frame is characterized by a peripheral wall reinforcing rib protruding from the frame member, the peripheral wall reinforcing rib extending along the peripheral wall and ranging at least from a boundary between the bed portion and the tower portion to a boundary between the tower portion and the arm portion.
