Abstract: A vehicle display control device includes: a map information acquisition unit that acquires map data around a vehicle; and an item display unit that overlaps a virtual item on a predetermined travel road on the map data and that displays the virtual item in a display area in a vehicle cabin. The item display unit overlaps and displays the virtual item on the map data, thereby guiding a driver of the vehicle toward the travel road on which the virtual item is displayed.

Abstract: A maintenance information management device includes an information registration unit configured to register vehicle identification information and maintenance information in a memory for each vehicle, an information update unit configured to update the maintenance information after the maintenance of the vehicle by adding maintenance contents to the maintenance information registered in the memory, and an information providing unit configured to provide the maintenance information when a provision request for the maintenance information is accepted.

Abstract: A dental treatment chair assembly with a treatment chair for keeping a patient in sitting position or in supine position, characterized by a treatment chair (bed) having a headrest for holding the head of a patient, and a backrest for holding the back and the waist of the patient, and instrument connection ports detachably connected to a dental treatment instrument which are disposed at the back or the side of said headrest, or at the back or the side of the backrest near by the headrest. In the preferred embodiment, the headrest is inclinably supported by the backrest, and a projecting part turning above is provide for compensating an estrangement between the headrest and the backrest.

Abstract: A system for use in skill acquisition, transfers and verification for performer has a simulated object, i.e., simulated head, to which the performer would perform clinical procedure. An image pickup, e.g., CCD camera, picks up an image of a point indicator provided on the performer or an instrument. Using the picked-up image, an image signal corresponding to the picked-up image is made. An image processor processes the image signal and generates data for showing a movement or tracks of the point indicator on a two-dimensional coordinate system. Thereby, a display shows tracks of the point indicator by using coordinate data.

Abstract: A seating sensor is provided on a seat back part and/or a seat cushion part of a seat in use for a vehicle such as an automobile, and calculates physical conditions, such as a height and weight of an occupant, to judge whether the subject on the seat is a human or an object. On the basis of the results of such calculation and judgement, the operation of an air bag is controlled. The seating sensor includes a sensing element which is variable in its electric resistance in response to the pressure variation, and the pressing force is detected on the basis of the variation of the electric resistance value.

Abstract: A rotary connector having a mutually rotatable inside case and outside case and having a flat cable with one end fixed to the inside case and the other end fixed to the outside case inserted in the space therebetween. A plurality of annular belts are inserted in the circumferential direction to bias the turnabout portion of the flat cable to prevent the flat cable from becoming loose and rattling in the space. Contact prevention members are inserted between the adjoining annular belts to prevent the adjoining annular belts from coming into direct contact with each other and to smooth the rotation of the rotary connector.

Abstract: Even when a headrest is moved, the hair of the patient is supported and the hair is surely prevented from hanging down.In a treating seat which can be lifted and lowered by a lifting device, stretched portions which are raised obliquely upwardly from shoulder supporting portions which support the shoulders of the patient are integrally formed. A recess into which a headrest for supporting the head of the patient is fitted is formed between the stretched portions. The side portions of the headrest are pivotally supported on opposing portions by pins, and supported by an engaging device in such a manner that the headrest can be angularly displaced. The stretched portions support the hair and prevent the hair from hanging down.

Abstract: A connector device includes a fixed housing fixed on a fixed member, a movable housing mounted on a rotatable member and freely rotatably combined with the fixed housing, and a flexible flat transmission line which serves to electrically or optically connect the fixed member to the rotatable member, which is wound in a spiral form and which is received in a space created by the fixed and movable housings. A clearance in an axial direction along the rotation shaft of the movable housing between the flat transmission line and the movable housing, or between the flat transmission line and the fixed housing is set to be smaller in the intermediate portion of the flat transmission line than in at least one of the end portions at which the flat transmission line is fixed on the housings so as to suppress occurrence of unpleasant vibration sound caused by collision between the flat transmission line and the housings.

Abstract: A brushless electric signal transmission apparatus comprising inner and outer housings coupled rotatably, a flat cable accommodated in an eddy form between these housings and including a plurality of conductors, plug-type connectors respectively mounted on opposite end portions of the flat cable, sockets into which the plug-type connectors are inserted, and covered lead wires which are the same in number as the flat cable conductors. Most of the flat cable conductors are connected to their corresponding covered lead wires via the plug-type connectors and the sockets. The unset flat cable conductors are connected to the unset covered lead wires via bus bars provided at the plug-type connectors.

Abstract: A plastic optical fiber cable with a ferrule in which a plastic sheath of the end side of the optical fiber cable is removed to expose a plastic optical fiber from the end of the optical fiber cable, and the ferrule is secured to the outer periphery of the end side of the optical fiber cable, wherein the ferrule is axially formed as a combination of a plastic cylindrical member for forming the end of the ferrule, and a metal cylindrical member for forming the base end, wherein the plastic cylindrical member is in contact with the enlarged part of the end of the optical fiber core at the inner peripheral surface of the end side to be secured to the end of the optical fiber core, and the metal cylindrical member is contacted under pressure with the outer periphery of the end of the plastic sheath by a stopper projecting from the inner peripheral surface of the metal cylindrical member so as to be fastened to the plastic sheath.

Abstract: This disclosure relates to a simple mounting structure for a dental X-ray apparatus. The structure is used in combination with a substantially horizontal treatment bed in such manner that irradiation tube of an X-ray head is designed to take a correct position with respect to the mouth region of a patient lying on the treatment bed with his head resting on the headrest of the bed. The structure includes the treatment bed, an X-ray head support connected to one side of the bed and made up of an assembly of a plurality of hollow tubes adjustable in length in the three-dimensional directions of length, width and height of the bed and an X-ray head mounted at the end of the support and swingable in a back-and-forth direction with respect to an axis of the irradiation tube. The irradiation tube is mounted on the X-ray head and movable toward and away from the mouth region. The structure permits simple and correct positioning of the X-ray apparatus with respect to a patient lying on the bed.

Abstract: An apparatus for the simultaneous measurement and remote recordation of the depth of the gingival sulci and other similar anatomical recesses. The apparatus comprises a periodontal depth probe with a protruding, removably-attached cylindrical probe tip partially ensheathed by a slideable tubular sleeve which is electrically connected via a transducer within the probe body to a remote recording device. Translational movement of the slideable tubular sleeve partially sheathing the probe tip varies an electrical signal between the probe and the remote recording device according to the length of probe tip exposed. An operator-controlled foot switch is connected between the probe and the remote recording device to allow the operator to insert the probe tip into the gingival sulcus and adjust the slideable sleeve until it touches the margin of the gingiva before actuating the remote recording device.
