Abstract: An imaging tube 210 includes an imaging lens and an illumination unit. A cap part 230 including a penetration part in which the imaging tube 210 penetrates is included at a leading end part of amain body part 220. A protective tube 212 that protects the entire circumference of the imaging tube 210 is attached to the imaging tube 210. A holding part 235 that holds an end part of the protective tube 212 with the imaging tube 210 is formed in the penetration part of the cap part 230. When being rotated in a first direction, the cap part 230 is moved in a direction opposite to a protruding direction of the imaging tube 210. When being rotated in a second direction opposite to the first direction, the cap part 230 is moved in the protruding direction of the imaging tube 210.

Abstract: Foreign matters of variable size in the interior of one's auditory canal are removed infallibly. An image capturing tube 220 adapted to be inserted into one's auditory canal to output an image of an interior of the auditory canal, a suction tube 230 provided along the image capturing tube 220 to suck a foreign matter in the interior of the auditory canal, and a main body unit 200 provided with the image capturing tube 220 and the suction tube 230 are included. The image capturing tube 220 includes a camera 240 adapted to capture the image of the interior of the auditory canal, and to a tip end of the suction tube 230, a dust collecting tube 232 is attached.

Abstract: A pipe endoscope includes: a transparent observation container having a bottomed cylindrical shape which is open on a base end side and sealed on a tip side; a scope which is inserted into the observation container and includes an objective lens at a tip of the scope; and an image processing device which is connected to the scope and processes information collected by the scope to display a video image. The observation container includes: a protrusion which is projected to the tip side beyond a sealed bottom part having light-transmitting property, and a tip of which is processed to have curvature; and a detachable light source which irradiates the periphery of the bottom part with light.

Abstract: A blood analyzer capable of obtaining a blood analysis result instantaneously without sampling blood but rather applying a DC current to blood flowing through an artery and irradiating it with an ultrasonic wave is provided. It is equipped with a main measurement unit 110 having a positive electrode and a negative electrode placed apart from each other, ultrasonic wave transmitting/receiving probes, which are sandwiched between the positive electrode and the negative electrode and placed adjacent to the positive electrode and negative electrode, and ultrasonic wave transmitting probes placed sandwiched between the ultrasonic wave transmitting/receiving probes, each of which is protruding from the surface and, provided inside of the main measurement unit 110, a measuring control unit comprising: a DC application unit, a positive electrode and a negative electrode, an ultrasonic wave output unit, an ultrasonic wave reception unit, and a component analysis.

Abstract: The present invention is about an unmanned boat automatic survey device and an unmanned boat automatic surveying method that automatically generate survey routes and automatically survey underwater and water bottom conditions under the survey routes. Under the present invention, a reference survey line is entered for generating a survey route (S1), and a plurality of survey routes are generated by translating the reference survey line at a fixed distance (S2). It then determines the distances of the generated survey routes and instructs a traversing order of the determined survey routes (S3), and causes the unmanned boat to navigate automatically according to the instructed traversing order. It surveys at least underwater or water bottom condition during the navigation (S5), and display and store the surveyed underwater or water bottom condition (S6).

Abstract: A plug and socket electrical connection for environments with high humidity and low temperatures has a socket with female connections (holes with an electrical terminals), a circular recess for receiving a mating part and tabs and a plug with a male connection (electrodes), the mating part and hooks. The electrical connections are protected from moisture by a snug fit and o-rings when the socket and the plug are electrically connected and the tabs and hooks hold the socket and plug together in place. The socket and plug are disconnected by movement of a handle holding the hooks that is part of the plug and can act as a lever to help the disconnection. The handle also provides a convenient finger hold for pulling the plug away from the socket.

Abstract: This invention concerns a remote control unmanned boat which can be freely operated by remote control and a remote control device. The remote control unmanned boat comprises a propelling power source 11 for generating a propelling power, a steering device 13 for freely varying the direction of advance, a first transmit-receive antenna 24 for receiving the signal transmitted by ratio from a control device 20, a first controller 15 for controlling the propelling power source 11 and the steering device 13 based on the signal received from the first transmit-receive antenna 14, a memory device 17 for memorizing the initial position set in advance, and a GPS antenna 16 for receiving the electric wave transmitted from an artificial satellite.

Abstract: An electrical mounting connector for a bi-pin fluorescent bulb has a lamp holder with two terminals and a cap with two pin guiding openings that snaps into the lamp holder such that two pins held in the two pin guiding openings will be held in contact with the two pin-shaped over a substantial portion of the pins along a parallel length of the pins. An alignment marking is provided on the lamp holder and a visual inspection point (such as a hole) is provided on the cap that compliment one another to provide a visual indication of when the lamp holder and the cap are properly assembled together. A drain is formed by one or more slots in the lamp holder to drain a space between the lamp holder and the cap accessed through pin guiding openings when the lamp holder and the cap are properly assembled together.

Abstract: An endoscopic cleaning device capable of properly removing wet cerumen from an auditory canal while the interior of an auditory canal is illuminated. The device allows an image of the interior of the auditory canal to be acquired while the auditory canal is being cleaned. The device has an ear picking main body that also serves as a light guide to provide the illumination. The ear picking main body rotates about a light guide containing the micro lens used to acquire the image, so that the image remains stable. The ear picking main body is inserted through a removable, elastically deformable tubular ear picking part having a through hole and an outer layer made of fibrous material. In this way light can be delivered to the end of the ear picking main body, and the fibrous material of the ear picking part can be used to remove wet cerumen.

Abstract: An endoscopic auditory canal cleaning device is provided which is capable of properly removing wet cerumen while keeping the interior of an auditory canal radiated with ample light.

Abstract: This invention concerns a remote control unmanned fishing boat intended for enjoyment of remote control fishing and a remote control device for use with the boat. The invention contemplates enabling the operator to advance the boat forward and backward and change the direction of the advance of the boat by manipulating the remote control device 2. By the operator using the remote control device 2 for actuating a depth sounder, the information concerning the depth of water and the condition of water bottom determined by the depth sounder is displayed on a monitor 41 of the remote control device 2. When the optimum position for fishing is found consequently, the operator is allowed to lower his fishhook in the water by manipulating the remote control device 2.
