Abstract: A sensor is provided with a sensing unit for generating electrical signals responding to a physical quantity, multiple terminals for an electrical connection with an external, multiple signal wires for transmitting the electrical signals to the terminals, a connector housing where the terminals are accommodated, and an electrically isolating case, to which the terminals are fixed. The terminals and the electrically isolating case are inserted into the connecter housing. Thus, the connecter housing can be singly formed without being insert-molded. Accordingly, the manufacture performance of the sensor can be improved.

Abstract: A temperature sensor comprises a thermistor element, a metal tube into which the thermistor element is inserted, two electrode wires joined to the thermistor element, two lead wires, which are covered by covering tubes with uncovered portions remaining and joined to the electrode wires, respectively, at the uncovered portions, and a housing having an inner hollow space into which the electrode wires and the lead wires are accommodated together with a resin. The sensor further comprises an insulating case disposed inside the housing and provided with a partition section for separating the joined portions of the electrode wires and the lead wires, the electrode wires and the lead wires from each other, and the inside of the insulating case is filled up with resin in a state that an opened end of the metal tube, the electrode wire and portions of the covered lead wires and uncovered portions thereof are inserted in the insulating case.

Abstract: The thermal deformations (thermal expansions and contractions) of a rib 105, a nipple nut 106 and a boss portion 201 are made substantially the same by making the coefficients of linear thermal expansion thereof substantially the same. According to the construction, even if an exhaust gas temperature sensor 100 is disposed in the vicinity of an exhaust manifold whereby the thermal deformations (thermal expansions and contractions) of the rib 105, the nipple nut 106 and the boss portion 201 are large, since the rib 105, the nipple nut 106 and the boss portion 201 are thermally expanded and/or contracted substantially all together, the loosening of threads due to a hot-cold cycle can be prevented.

Abstract: A thermistor type temperature sensor having a substrate made from an electrically insulating ceramic plate. A thin or thick film detecting resistor is printed on the substratum. A thick or thin film pull-up resistor may also be printed on the substratum, and trimming of the resistors is possible. The ratio of B-constant values for the detecting resistor and the pull-up resistor may be selected so that it is locate between 0.4 to 0.9 or 1.1 to 1.5. The detecting resistor may be constructed from thermistor sections of the same composition and the sections may be connected in parallel or in series. The thermistor sensor can be connected to the pipe through which a gas passes. When the sensor is connected to the pipe, the angle of the measuring plane may be adjusted, so that a precise measurement can be obtained.

Abstract: A small watercraft of the jet propelled type designed to be operated by a rider standing on a deck to the rear of a control mast. The deck is defined by a pair of upstanding sidewalls that are spaced apart a greater distance where they join the deck than above the deck so that a rider may place his feet in widely spaced fashion, but brance his legs against the inwardly extending portions of the upwardly extending projections.
