摘要:
A silent electromagnetic relay in which a predetermined degree of silencing effect can be maintained regardless of a change to the specification, a higher silencing effect can be obtained at the time of return, the parts control is easy, and the cost of manufacturing is low. A first silent spring is mounted in a position of an inward face of a moving iron to be attracted to an iron core of an electromagnet portion, and an L-shaped moving iron turning based on excitation and demagnetization of the electromagnet portion is housed in a housing that is a resin molded product. Furthermore, a second silent spring for coming in contact with an inner face of the housing is mounted to an outward face of the moving iron and on an opposite side to the first silent spring.

A power transmission belt having a body with a rubber layer defining spaced friction drive surfaces at laterally oppositely facing side surfaces. Short reinforcing fibers are embedded in the rubber layer in an amount of 15-50 parts by weight per 100 weight percent of rubber in the rubber layer. The short reinforcing fibers include polyamide short reinforcing fibers that make up at least 50 weight percent of the short reinforcing fibers embedded in the rubber layer. A plurality of the polyamide short reinforcing fibers project from the friction drive surfaces and have exposed, flattened ends. Flat particles of inorganic powder are adhered to the friction drive surfaces to reside captively between the flattened ends of the polyamide short reinforcing fibers and locations on the friction drive surfaces at which the short reinforcing fibers do not project.

The spacer is formed as an elastic member with no ends thereof, which is detachably attached, by exploiting its elastic deformation, onto a printed wiring board to which is fixed an electronic component having a component package, on one of whose surfaces connection terminals are arranged. Since the spacer is attached on the printed wiring board to enclose an electronic component so as to seal a gap formed between the electronic component and a printed wiring board, it is possible to prevent foreign objects entering the gap, so that failures, such as insufficient insulation, caused by such foreign objects are also prevented. Since the spacer is easily removed from the printed wiring board, it is recyclable and economical.

A method of sending local dial tone to the subscriber from the fixed subscriber unit (FSU) is described. The method can include receiving and memorizing DTMF dialing from a connected telephone. Outpulse this DTMF dial signal information from the FSU to the network. After establishing the wireless communication between the FSU and a wireless base station, providing a cut-through of the audio path between the network and the subscriber.

摘要:
A press-fit pin has a press-fitting portion having a plurality of bending portions which are to be elastically bent so that a bending stress generated in the press-fitting portion is dispersed to the bending portions. The press-fitting portion is to be press fit into a through hole. The press-fitting portion has a plurality of beams extending along a longitudinal axis of the press-fitting portion. The beams are elastically bent along a line parallel to the longitudinal axis when the press-fitting portion is press fit into the through hole. The press-fitting portion has a cross portion extending along the longitudinal axis of the press-fitting portion so as to connect the beams. The cross portion is elastically bent along a line parallel to the longitudinal axis when the press-fitting portion is press fit into the thorough hole.
摘要:
A server associates a permitted terminal identifier that identifies a permitted terminal permitted to perform tunnel communication to a first router with an endpoint address of a tunnel used in the communication of a permitted terminal. A second router that encapsulates a packet received from a requesting terminal, which requests the tunnel communication, inquires the server about an endpoint address associated with an identifier of the requesting terminal. The server notifies the second router of the target address that is the endpoint address associated with the identifier of the requesting terminal. The second router transmits the encapsulated packet to the target address. The first router to which the target address is allocated regards a received packet received at the target address as a packet used in the tunnel communication of the permitted terminal and decapsulates the received packet and then transmits the decapsulated packet to a communication destination.
