摘要： PURPOSE: To provide an electromagnetic relay which is small and has long life by providing an isolating member that isolates a contact portion from the coupled part of a drive portion and a movable portion. CONSTITUTION: This electromagnetic relay 1 comprises a contact portion 4 in which a moving contact 2 and a fixed contact 3 open and close; an oscillating portion 5 which oscillates the moving contact 2 of the contact portion 4; a fixing portion 7 by which the oscillating portion 5 is held in such a way as to freely oscillate; and a case 18 covering both the contact portion 4 and the oscillating portion 5. A mold guide portion 14 is formed integrally with a mold portion 11 to which an armature 10 having the moving contact 2 secured thereto is integrally secured in such a way that the portions of contact between the armature 10 and a yoke 16 are isolated from the contact portion 4 comprising the moving contact 2 and the fixed contact 3. The mold guide portion 14 of the oscillating portion 5 is formed on the side face of the armature 10 to form a partition between the gap between the armature 10 and the yoke 16 and the contact portion 4. Therefore, the guide portion 14 prevents dust generated by the collision of an unmagnetized plate 17 with the yoke 16 from scattering in the direction of the contact portion 4, so that contamination of the contact portion 4 by the dust can be prevented.

摘要： PURPOSE:To simplify a structure, and also reduce electric power consumption by shifting a load of an armature composed of a movable contact point spring and a suction force generated by a permanent magnet in the direction for being strengthened on the normal open side, and sucking the edge part of the armature by means of an open side magnetic pole part even if a magnetic flux generated by a coil is small. CONSTITUTION:Though a movable contact point spring 1 and an armature 2 are formed integrally in the central part through an insulating body 6 so as to become parallel with each other, a support part 11 is twisted to the spring 1, so that a plane containing the support part 11 and a plane containing the spring 1 can cross each other when seen from the side surface. When seen from the side surface in an electric current unimpressed condition after the spring 1 is installed in a box body in this way, the support part 11 is supported with the box body, so that a plane containing the edge surfaces of magnetic pole parts 31 and 32 and a plane opposed to the magnetic pole parts 31 and 32 of the armature 2 can be expanded in one direction. Thereby, a suction force of the magnetic pole parts 31 and 32 generated by a permanent magnet 7 becomes asymmetrical between left and right as shown by a broken line, so that the suction force generated by the open side magnetic pole part 32 can be shifted in the direction for becoming larger than the suction force generated by the closed side magnetic pole part 31.

CONSTITUTION:The system is provided with a response signal detection means 100. When transmitter/receiver 1 is disconnected, a call is originated in a state of connecting a speaker 2 and a called party answers the call, a response signal (the polarity inversion of the DC voltage supplied from the exchange to the subscriber line or stopping a calling sound during the return) returned through a subscriber line 20 from an exchange 30 is detected and the speaker 2 is automatically disconnected and the transmitter/receiver 1 is connected by the means 100.

摘要： PURPOSE:To suppress deformation, etc., of covers due to the heat at the time of mounting and improve the productivity by making the external connection terminal part visible with eyes and thickening the thickness of the covers without widening the mounting surface area of a realy on a circuit substrate. CONSTITUTION:The external face of circumferential wall of a cover 6 to be mounted on a relay main body 2 is so made as to locate near the region formed in the case the tips of respective external connection terminals 22a-1', 22b-1', 22b-2' of the main body 2 are connected. Also, in the region corresponding to each external connection terminal, a connection region for at least a circuit substrate 4 of each external connection terminal is composed while a recessed part which can be observed with eyes from right above or obliquely above outside is formed. As a result, the thickness of the circumferential wall of the cover 6 except the regions corresponding to the external connection terminals is made thick in the region of the external connection installation, that is, the range of the region where connection electrodes of the substrate 4 are formed. Consequently, deformation and strain and damage of the cover due to the heat at the time of being mounted on the substrate 4 are prevented and the productivity is improved.

摘要： PURPOSE:To realize the lowering in height and automatated manufacture of relay without deteriorating magnetic characteristic by superposing iron cores of respective iron segements of first and second iron core segments integrating iron cores divided into two parts and the one yoke at the center of electromagnetic coil. CONSTITUTION:The iron segments 35, 35' are integrated in such a manner that iron cores 36, 36' are protruded from the one side of the yokes 37, 37' and the iron cores 36, 36' are respectively inserted into a through hole 33 from the opposing apertures of bobbin through hole 33 and overlapped in the vertical directions. Meanwhile, the contact pole 38 is supported in order to causes the internal corner of bending to abut against the upper external side or yoke 37 and maintains abutting with a pressing force of a plate spring 40 and the bending end 39 is opposed by the adequate distance to the end of yoke 37' in almost parallel thereto. In the electromagnet 31 thus formed, when the specified current is applied to a coil 34, the contact pole 38 rotates clockwise around the supporting axis, the end 39 is magnetically attracted to the yoke 37' of iron segment. When current supply stops, a magnetic force for attracted disappears and the contact pole 38 returns to the initial mode.

摘要： PROBLEM TO BE SOLVED: To enable a terminal device in a radio communication network to be started in a remote manner. SOLUTION: A base station device 110 includes a radio-receiving section 111, a storing section 112, a request-receiving section 114, a determining section 115, and a distributing section 116. The radio-receiving section 111 receives the identification information of the terminal device, from a terminal device located in the surrounding area by radio. The storing section 112 stores the identification information received by the radio-receiving section 111. The request-receiving section 114 receives a start-request, containing identification information of the terminal device to be started from the other communication device. The determining section 115 determines whether the identification information contained in the start request received by the request-receiving section 114 is stored in the storing section 112. When the determining section 115 determines that the identification information is stored in the storing section, the distributing section 116 distributes a starting instruction for the terminal device to be started which is indicated by the identification information by radio to the surrounding area.
