摘要:
The gas sensor includes a sensor element having electrode pads formed in its electrode forming surfaces at the proximal end portion thereof, an insert-holding insulator insert-holding the sensor element, a housing insert-holding the insert-holding insulator, and a terminal unit. The proximal end portion of the sensor element is held by the terminal unit which includes a pair of proximal end insulators formed with metal terminals at their inner surfaces, and a spring member pressing the proximal end insulators in a direction that they approach each other. Each of the proximal end insulators includes an insulator contact portion in contact with one of the electrode forming surfaces. The insulator contact portion is located closer to the proximal end of the sensor element than a terminal contact portion at which the metal terminal contacts a corresponding one of the electrode pads.

A signal transmission system includes a transmission apparatus and a reception apparatus, the transmission apparatus including: a first portion that converts a video signal into differential signals, converts a vertical synchronization signal into a common mode signal, and transmits the converted signals to the reception apparatus via three pairs of signal lines; and a second portion that converts a horizontal synchronization signal into differential signals, converts a first console signal into a common mode signal, transmits the converted signals to the reception apparatus via a single pair of signal lines; the reception apparatus including: a third portion that restores the differential signals to the video signal, and restores the common mode signal to the vertical synchronization signal; and a fourth portion that restores the differential signals to the horizontal synchronization signal, and restores the common mode signal to the first console signal.

Sealing material is injected into a cap receiving an electric cable joint without remaining air bubbles. The cap has an opening at both ends and receives the joint, the electric cable being in the upper side and the joint being in the lower side. The sealing material is injected into the cap from the lower opening. The joint is inserted into the cap from the upper opening. Or, the joint is received in the cap, the sealing material is injected into the cap from the upper opening, and the cap position is reversed. Or, the sealing material is injected into the cap, from the upper opening, the joint is inserted into the cap, and the cap is reversed. A cap holder receives the cap such that the upper and/or lower opening of the cap is covered.

An improved manufacturing method for a gas sensor is provided which is capable of establishing a required hermetic seal in a body of the gas sensor. The method includes preparing a sensor assembly including a housing, an air cover, an insulation porcelain, and a sensor element, pressing the air cover against the housing to fit an end of the air cover on an end of the housing to form an overlap thereof, and welding the air cover to the housing over the overlap. The welding is accomplished while pressing the air cover against the housing, thereby compressing an elastic member in the air cover to establish a hermetic seal between the sensor element and the housing.

The air cover may be tack welded to the housing before welding the overlap for securing a positional relation between the air cover and the housing.

A gas sensor element is inserted into a housing having a base end and is fixed with respect to the housing. Terminal electrodes are provided on the base end of the sensor element. An atmosphere-side cover including an insulator with terminal accommodation holes is provided on the base end of the housing. The insulator also has an element accommodation hole (communicating with the terminal accommodation holes) in which the base end of the sensor element is placed. The insulator has ribs forming inner surfaces defining the element accommodation hole. The rib thickness is smaller than that of the sensor element base end. Metal terminals are at least partially placed in respective terminal accommodation holes and have connecting portions with leads for external electrical connection. The ribs are located between the metal terminals to form spaces between the metal terminals. As the sensor element base end is placed in the element accommodation hole, terminal electrodes on the base end come into contact with the metal terminals and thereby electrically connected with the leads.

Cathode electrode part 5 of flat plate-like element 1 is joined with cathode com terminal 7 with a conductive adhesive or the like. Element mounting part 6a of anode terminal 6 is provided with a pair of joint parts 6b for wrapping anode electrode part 4 from both sides. The tips of joint parts 6b and anode electrode part 4 are joined by laser welding such that the ratio (w/d) of the width (w) of each tip of joint parts 6b and the diameter (d) of the welding trace to be welded is 0.5 to 1.5, and more preferably, 0.5 to 1.25 for providing low ESR means for concentrating the quantity of heat at the time of welding on welding parts 6c without escape. Therefore, a stable welded state is obtained, so that the ESR is improved for achieving low ESR of the solid capacitor.
