When the sleeve (3) is rotated, the locking portion (3B) disposed on the sleeve (3) slides against one or the other of the inclined cam surfaces (47A-1 and 47A-2), and is inserted into the engaging groove portion (47B) of the locking groove portion (47). The locking portion (3B) reaches the locking seat portion (47b) through moving over the cam portion (47a) disposed on the engaging groove portion (47B). The spring washer (29) urges the locking portion (3B) to be seated on the locking seat portion (47b).

An intermediate electrical connector device, which easily enables “floating”, includes an intermediate board (20) having two connecting sections (23A) and (24A), which are respectively formed at the edges (23) and (24), to connect between two connecting bodies (40) and (40′), and a holding body to hold the intermediate board between two connecting sections. The holding body is divided into a plurality of sub-members (10) and (10′) at a surface perpendicular to the fitting direction between the two connecting bodies. The intermediate board is held by one of the sub-members through at least partial fitting, and forms space from another sub-member. The sub-members can be displaced relative to each other on the surface perpendicular to the fitting direction at least one direction parallel and perpendicular to the intermediate board.

In a quadrupole mass spectrometer which measures partial pressure strength according to a gas type in a vacuum system from ion current intensity, a quadrupole mass spectrometer with a total pressure measurement electrode has a total pressure measurement electrode for examining an ion density disposed in a demarcation space which is comprised of a grid electrode and an ion focusing electrode. And, a vacuum system is provided with only the quadrupole mass spectrometer which measures partial pressure strength according to a gas type in the vacuum system from an ion current intensity and does not have an ionization vacuum gauge other than the quadrupole mass spectrometer.

In a transmission circuit board, ground terminal portions (10) are disposed at every other two rows in both end columns. Each of signal circuit layers (20) includes at least a pair of adjacent signal connecting portions electrically connected to a pair of the wiring portions (21, 22) arranged in parallel in a row direction and the column direction different from those on an adjacent signal circuit layer. Each of the ground layers is electrically connected to at least one of the ground terminal portions (10) in the both end columns.

An electrical connector includes a housing and a plurality of terminals having a plate shape to be attached to the housing in parallel with a narrow pitch. The plurality of the terminals has holes at opposing portions thereof in a pitch direction such that opposing areas between adjacent terminals is reduced. The housing has a groove bridging over the plurality of the terminals in the pitch direction such that a space is formed between the adjacent terminals.

A developer supply device provided is in contact with a developer carrying device. It comprises a surface member having at least one opening elongated in an axial direction of the developer supply device. The number of cellular walls counted in the circumferential direction is increased without increasing the number of openings so that the power of scraping the developer is increased. As a result, the dirty background on the print is minimized, thus enhancing the image quality.

A cover equipped electrical connector includes a housing (11) to be provided on a circuit board (P); a terminal (20) having a contact section (23) and a connection section (24) projecting from the housing (11) onto the circuit board (P); a pressure member (13) movable between an open position where a flat type cable is inserted into the housing (11) and a closed position where the pressure member (13) presses the flat type cable against the contact section (23); a cover member (30) movable between a stand-by position where the connection section (24) is exposed and a cover position where it covers the connection section (24); and a support member (36) for supporting the pressure member (13) and the cover member (30).
摘要:
A mobile terminal device searches a beacon signal sent from an access point through a wireless LAN, and obtains beacon frame information for certification and connection permission. The mobile terminal device then holds network information necessary for data communication with the access point, and measures a period of time between each time the data communication is performed. The mobile terminal device terminates electric power supplied to hardware for performing the data communication with the access point when the data communication is not performed within a predetermined period of time and network connection is terminated. The electric power is supplied to the hardware when it is necessary to send data to the access point through an input operation of the mobile terminal device while the electric power to the hardware is terminated. Accordingly, the mobile terminal device can be frequently disconnected from the network for a very short period of time.
