Abstract: As a conventional antifouling measure to prevent adherence of aquatic organisms to a submersible sensor unit, a grease containing a stimulant, such as mustard, capable of repelling aquatic organisms is applied onto a sensing part thereof, thereby preventing adherence of the aquatic organisms. However, the irritant-containing grease applied onto the sensing part will come off within one to two months, resulting in disappearance of its effect. Thus, it is necessary to perform work of pulling up the submersible sensor unit and re-applying the grease, in each case. The present invention provides a water flow resistant submersible sensor unit which comprises an aquatic organism adherence preventive film capable of preventing adherence of aquatic organisms even when used in the submersible sensor unit for about half a year, almost without involving any underwater movement, and capable of, after use, being easily peeled off from the submersible sensor unit.

Abstract: A hydrogen sensor includes a communication terminal, a plurality of identification terminals, and an ID setting section. The communication terminal is connected to a first communication bus or a second communication bus, and communicate with a vehicle ECU. Each of the plurality of identification terminals is set to either an open state (OPEN) in which the identification terminal is not connected to any potential or a grounded state (GND) in which the identification terminal is connected to a ground potential. The ID setting section sets an identifier in either a standard format or an extended format, according to a difference in the communication bus to which the communication terminal is connected.

Abstract: A bobbin unit includes a base portion and a coil winding portion on which a conductor is wound. A hole is formed in a central part of the base portion to allow an armature to pass through. Coil side terminals to which ends of the conductor are fixed and signal input terminals to which an external signal is entered are provided at opposite ends of the base portion with the hole located in between. The coil side terminals are electrically connected to their corresponding signal input terminals inside the base portion. A coil is formed on the coil winding portion by winding the conductor. The ends of the conductor are fixed to the respective coil side terminals.

Abstract: An insulating bushing of an electret condenser microphone is disposed on the rear side of a back electrode portion and abuts against the rear surface of back electrode plate. When a predetermined force is applied to the insulating bushing from the opened end of the case by way of a fixing ring and a printed circuit board, the insulating bushing deforms so as to fit into a gap formed between the inner peripheral face of the case and an end portion of the back electrode plate. Since the insulating bushing fits between the inner peripheral face of the case and the end portion of the back electrode plate, the back electrode plate is positioned and fixed with respect to the case in a state where the back electrode plate and the case are electrically insulated from each other.

Abstract: A bobbin unit includes a base portion and a coil winding portion on which a conductor is wound. A hole is formed in a central part of the base portion to allow an armature to pass through. Coil side terminals to which ends of the conductor are fixed and signal input terminals to which an external signal is entered are provided at opposite ends of the base portion with the hole located in between. The coil side terminals are electrically connected to their corresponding signal input terminals inside the base portion. A coil is formed on the coil winding portion by winding the conductor. The ends of the conductor are wound around the respective coil side terminals and fixed thereto by arc welding. Since the conductor is electrically connected to the signal input terminals when the ends of the conductor are fixed to the coil side terminals, connection of the ends of the conductor constituting the coil to the signal input terminals is made easy.
