摘要:
An electrical connector comprises a connector housing having a retainer receiving opening and a terminal insertion opening. A retainer is receivable in the retainer receiving opening and has a terminal receiving aperture that substantially aligns with the terminal insertion opening to form a terminal receiving path. The retainer is moveable between a first position and a second position. An elastic lance extends from a lower edge of and substantially beneath the terminal receiving aperture. A shoulder is formed on an upper surface of the terminal receiving aperture opposite from the elastic lance. An engaging claw extending from the elastic lance extends into the terminal receiving path in the first position for temporarily engaging a terminal, and the shoulder extends into the terminal engaging path in the second position for permanently engaging the terminal. The engaging claw is removed from the terminal receiving path in the second position.

A holding member includes a base section, a pair of leg sections, and inclined sections positioned along tip portions of the pair of leg sections. The base section is plate-like shape. The pair of leg sections extend in approximately equal directions to each other, and are configured to fit into a through hole of an electronic circuit board and contact an inner surface of the through hole. The inclined sections are positioned along respective tip portions of the pair of leg sections and extend in directions approaching each other and facing in opposite directions, while being inclined relative to a width direction of the base section. Furthermore, the inclined sections contact and press each other so that a tip of at least one of the pair of leg sections advances along the axis which is angled relative to the width direction of the base section when the pair of leg sections are pushed into the through hole and contact the inner surface of the through hole.

A monitoring apparatus for monitoring communication configurations of a plurality of client devices connected to a server, the monitoring apparatus includes: a processor for controlling the communications between the client devices and the server in accordance with a process including: receiving from each of the client devices communication condition information and storing latest communication condition information of each of the client devices; determining at a time interval whether any of client devices became incapable of communication with the server by checking the latest communication condition information of each of client devices; and upon detection of at least one of the client devices for which obsolete communication condition information is stored, issuing a notice indicating that the at least one of the client devices are incapable of communication with the server.
摘要:
An electrical connector includes a connector housing having a contact engaging section with contacts which engage mating contacts, and a wire holder holding wires connected to the contacts. The connector cover is capable of moving between partially engaged position and fully engaged position. The partially engaged position is the position in which a rear end of the wire holder is housed in and the fully engaged position is the position in which the rear end of the wire holder projects from a rear end opening. The connector housing has a first engaging section engaging a mating connector in the partially engaged position. The connector cover has a second engaging section engaging the first engaging section and restraining disengagement of the first engaging section from the mating connector in the fully engaged position.
摘要:
A ferromagnetic double quantum well tunneling magnetoresistance device is disclosed that utilizes a two-dimensional electron (positive hole) system to obtain an infinitely great magnetoresistance ratio. Also disclosed are a sensitive magnetic sensor and a nonvolatile storage device derived from that device. In structural terms of the device, a first and a second quantum well layer of ferromagnetic material (4, 8) in each of which the quantum confinement for carriers is established in a two-dimensional electron (positive hole) state are each sandwiched between a pair of barrier layers of nonmagnetic material (2, 6, 10) through which the carriers can tunnel. The first and second quantum well layers (4, 8) have a difference in coercive force so that when an external magnetic field is applied thereto only one of them may be reversed in the direction of magnetization. As a result, if magnetizations of the two quantum wells are parallel to each other, tunneling is allowed to occur, and if they are antiparallel to each other, tunneling is inhibited. A infinitely great tunneling magnetoresistance ratio is thereby obtained.
