摘要:
A low insertion-withdrawal force electric connector is disclosed wherein a pin is mounted on one side wall of a male housing; a groove into and out of which said pin is movable is provided in a hood of a female housing; a cam lever is pivotally mounted on said hood; and the cam lever has at its front end an eccentric cam groove which is engageable with the pin so as to cause said two housings to be fitted and disengaged relative to each other in response to the pivotal movement of said lever. A fitting-side acting surface of the eccentric cam groove against the pin is disposed generally perpendicular to the direction of advance of said pin when the two housings are completely fitted together.

In locking metal terminals in a connector, a terminal locking jig having engaging prongs which are extended respectively so as to be engaged with terminal accommodating chambers in the rear end portion of a connector housing is inserted into a terminal-locking-member accommodating chamber formed surrounding the terminal accommodating chambers, to drive the metal terminals which are not completely locked yet to the positions where the metal terminals are completely locked, and thereafter a terminal locking element having engaging prongs which are extended in the same manner is inserted into the connector housing from the rear or side. Thus, the terminal locking member can be engaged with the connector housing with ease.

The present technique relates to a reception apparatus, a reception method, a program, and a reception system capable of starting decoding of data in a short time. A reception apparatus according to an aspect of the present technique includes a demodulation unit configured to demodulate a modulated signal used to transmit transmission control information about data and the data to be transmitted, a first decoding unit configured to decode the transmission control information obtained by demodulation performed with the demodulation unit, a storage unit configured to store the data obtained by demodulation performed with the demodulation unit, and a second decoding unit configured to decode the data stored in the storage unit on the basis of the transmission control information decoded by the first decoding unit. The present technique can be applied to a receiver receiving an OFDM signal of DVB-C2.

A receiving apparatus for receiving an orthogonal frequency division multiplexing (OFDM) signal including a frame having one frame length of a plurality of patterns. The apparatus comprises an acquiring section to acquire information regarding a preamble signal from an OFDM signal from a transmitting apparatus; a frame determining section to determine whether the one frame length is short in the frame based on the information regarding the acquired preamble signal; and a time interpolating section to obtain transmission path characteristics by comparing a pilot contained in the preamble signal with a known pilot corresponding to the pilot in a phase of transmission, when the frame determining section determines that the one frame length is short in the frame, and to interpolate a data portion in a time direction based on transmission path characteristics.

To provide an effective and simple process for producing 4-fluoroisoquinoline-5-sulfonylhalide or a salt thereof, and a simple method for separating for purification of the product from a by-produced position isomer thereof. The process for producing 4-fluoroisoquinoline-5-sulfonyl halide or a salt thereof, characterized in that the process includes reacting 4-fluoroisoquinoline or a salt thereof with sulfuric anhydride in the presence or absence of sulfuric acid, to thereby form 4-fluoroisoquinoline-5-sulfonic acid or a salt thereof, and, subsequently, reacting the formed sulfonic acid compound with a halogenating reagent.

A method for separating p-xylene by separating and recovering only p-xylene from a p-xylene-containing raw material mixture under high-temperature and high-pressure conditions using a zeolite membrane as a separating membrane is provided. The p-xylene partial pressure at the raw material side of the separating membrane is kept at a sufficiently high pressure and the p-xylene partial pressure at the recovery side of the separating membrane is controlled at a pressure which is not higher than the inflection point of p-xylene adsorption curve. This method for separating p-xylene using a zeolite membrane as a separating membrane can secure a sufficient p-xylene permeation amount and has industrial applicability.
摘要:
A connector includes a first connector housing having a resiliently deflectable lock arm in an outer wall of the first connector housing and a second connector housing having a lock arm engaging with a locking piece fitted in the first connector housing. In the complete engaged state of the pair of connector housings, the lock arm engages with the locking piece so that the first and second connector housings are secured to each other. The connector further includes an engagement confirming member movably attached to the lock arm and an engagement retaining wall standing and positioned adjacently to the engagement confirming member. In the complete engagement of the pair of connector housings, the engagement confirming member is moved onto a top portion of the engagement retaining wall to prevent the lock arm from deflecting. The engagement confirming member is preferably attached movably in a substantially orthogonal direction to the engagement direction of the connector housings.
摘要:
A waterproof tap cover for use in a waterproof connector which prevents a waterproof tap from being damaged when a terminal metal member is removed from a connector housing in the waterproof connector. The waterproof tap, which is formed of rubber and includes a plurality of insertion holes respectively formed so as to oppose a plurality of terminal storage chambers formed in the connector housing, is fitted with the rear portion of the connector housing, and the waterproof tap is fixed by the waterproof tap cover which has a plurality of through holes corresponding to the insertion holes. Chamfered escape recesses are formed in the hole edge portions of the through holes adjacent the waterproof tap in order to accommodate ridge portions of the waterproof tap when the terminals are withdrawn from the connector housing so that the connector can be resealed when the terminals are inserted again.
