Abstract: A placement device is provided for causing a catheter to be placed inside of a body. The placement device includes an insertion unit, a transmission unit and a supply member. The supply member includes a supply unit main body, and a projection. A through-hole is formed on the inner peripheral surface of the supply unit main body at a position closer to a distal end side of the supply portion main body than the projection, and the through-hole communicates with an inside of the supply unit main body at the distal end side of the supply unit main body.

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: 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 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: The invention intends to provide an ear-pick, which is capable of safely and securely remove earwax, and foreign objects such as insects and water. Endoscopic auditory canal cleaning apparatus comprising: an ear-pick main body, which is equipped with a scraping part at its distal end and is formed to guide light to said distal end; a light source, which generates said light; a light source generates light; a fiber scope, which captures images in the inside of the auditory canal; a display unit, which displays the images captured by the fiber scope; and a holding part, which holds the ear-pick main body and the fiber scope; wherein the fiber scope passes through a hollow opening provided in the holding part; and the holding part holds the fiber scope to be able to rotate freely.

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.
