An electronics packaging system (1) including a printer (3), a placing unit (4) and a reflow unit (5), wherein a printed wiring board (2) is carried while being kept in an upright position. The printed wiring board (2) has solder printed on all the lands thereof at the same time, the electronic parts (10) are all placed on the lands at the same time, and the electronic parts (10) are all soldered to the lands at the same time. Thus, the system (1) can be designed more compact, and the electronic parts packaged in a shorter time.

A gas pipe including a tube of expansible material defining a passage for gas and capable of expansion, when heated, to close the passage upon carbonization. The tube is surrounded by a cylindrical noninflammable member.A joint for connecting gas pipes which includes a tube of expansible material contained in a metallic tubular member and defining a passage for gas. The tube is capable of expansion, when heated, to close the passage upon carbonization.A method of manufacturing thermally expansible rubber tube for the gas pipe and the gas pipe joint. About 2 to 30 parts by weight of oxidized, thermally expansible graphite powder is mixed with 100 parts by weight of raw rubber, and a predetermined quantity of a curing agent and a cure accelerator are added to the rubber and graphite mixture, followed by its formation into a tubular shape.

In a facsimile communication system, a user's terminal facsimile apparatus stores a plurality of character strings each composed of instruction words and data to be sent to a host apparatus for identifying one of communication services offered from the host apparatus. Accordingly, when one of the stored character strings is selected and executed, the corresponding communication service is offered from the host apparatus to the user's terminal facsimile apparatus. The character string may be produced by actually communicating with the host apparatus so that a transmission timing of the data in the character string can be precisely matched with what is required by the host apparatus.
摘要:
Plural thin plate projecting portions are integrally and projectingly provided on an outer peripheral portion of a side plate member of a bobbin. Each of the thin plate projecting portions comprises a circumferential rib, a slit portion and a reinforcement rib. The circumferential rib is provided on an outer peripheral face of the thin plate projecting portion of the bobbin and then a gap is formed between a claw-shaped magnetic pole of a rotor core and the thin plate projecting portion. A varnish material etc. is caused to adhere to and harden in this gap. By filling a root portion of the claw-shape magnetic pole of the rotor core with varnish material, the resonance vibration in the rotor core can be restrained. As a result, an alternating current generator for use in a vehicle having the small magnetic noise can be obtained.
