Abstract: A gas sensor (1) including a sensor element (10); a metallic shell (138); a tubular outer surface member (190) attached directly or indirectly to the metallic shell, constitutes an outer surface of the gas sensor, and extends toward a rear end side in relation to the metallic shell; and a tubular protection member (210, 220) which is detachably fixed to a fixation region C1, C2 of an outer circumference of the outer surface member. The protection member includes a first arc portion (212), a second arc portion (222), and a fixation portion (214,224) brought into contact with and is fixed to the fixation region. When the protection member fixed to the outer circumference of the outer surface member by fixing the fixation portion to the fixation region is viewed in the axial O direction, the first arc portion and the second arc portion cover in total at least 90% of the entire circumference of the outer surface of the outer surface member.

Abstract: A gas sensor (1) including: a sensor element (5) having an electrode pad (31, 32, 34, 35); a metallic terminal member (41) electrically connected to the electrode pad; and a lead wire (37) electrically connected to the metallic terminal member. The metallic terminal member has a forward-end-side terminal portion (43) which comes into contact with the electrode pad and a rear-end-side terminal portion (45) which is connected to the lead wire. The forward-end-side terminal portion has a bent portion (43d), and an element contact portion (43e) which comes into contact with the electrode pad. The rear-end-side terminal portion has a crimp terminal portion (45a) which forms a tube or a part of a tube, surrounds a conductor (37a) of the lead wire, and fixedly holds the conductor when crimped. Further, the maximum thickness t1 of the bent portion is greater than a maximum thickness t2 of the crimp terminal portion.

Abstract: A malfunction analysis support program causes a computer to perform a log data acquisition step, an action reproduction step, a three-dimensional data display step, a processing step being at least one of a program operation display step, a waveform display step, or a video display step, and a time synchronization step. The log data acquisition step obtains log data temporally sequentially recording a state of an operational part and input-output data of a control signal. The action reproduction step generates action reproduction simulation data obtained by causing a virtual object-to-be-controlled to reproduce an action based on the log data. The three-dimensional data display step displays the action reproduction simulation data as three-dimensional data. The time synchronization step synchronizes time between three-dimensional data displayed by the three-dimensional data display step and data displayed by the processing step.

Abstract: A container having an injection needle-detaching means for containing used injection needles comprising: a closed container for containing injection needles, and a needle-detaching means for detaching a slip type injection needle from a syringe, said needle-detaching means comprising a first opening provided in a wall of said container for inserting said needle attached to said syringe, a second opening extending laterally from said first opening, and a sliding portion provided on each of both sides of said second opening, said first opening having a size larger than the largest part of said needle, said second opening having a width larger than the diameter of the nozzle of said syringe and smaller than the diameter of the hub of said needle, each sliding portion having a wedge-like shape.
