摘要:
The present invention relates to a robot for individually removing requested books from their prescribed locations in bookracks and returning them, a hand mechanism for the robot, and an automated library book handling system incorporating the robot. The robot comprises a carriage that moves itself around a bookrack in which are formed a plurality of shelf sections having shelf section identification information indicated thereon, in which library books having book identification information indicated thereon are stored upright in shelf sections prescribed therefor; and mounted on the carriage are a hand mechanism; a control unit for controlling three-dimensional motion of the hand mechanism opposite the bookrack; a mobile computer for obtaining, based on instructions from a library book checkout and return counter, the identification information for a requested book along with the requested book's prescribed shelf section storage location, and performing guidance control of the carriage and the three-dimensional motion of the hand mechanism; and a mobile power supply. The hand mechanism of the robot further comprises an identification information recognition unit for detecting shelf section identification information indicated on the bookrack as well as book identification information indicated on the library books, and recognizing a requested book's prescribed shelf section storage location, and a requested book present at that prescribed shelf section storage location; a book pullout mechanism for pulling-out a requested book from a row of books in a shelf section; and a book-holding mechanism for removing the pulled-out book by grasping the book across the thickness direction thereof.

The present invention relates to navigation of an autonomous vehicle capable of autonomously tracking a route toward a destination. The present invention provides a system comprising the steps of forming a route for an autonomous vehicle with a plurality of information storing elements placed at specific locations in line along a passageway, each beacon storing its own location information on the route, mounting an information retrieving section on the autonomous vehicle so that as the vehicle travels, the information retrieving section comes in sufficient proximity to the information storing elements in sequence, transmitting radio waves between the information retrieving section and information storing element, supplying, through the transmission of the radio wave, electricity from the vehicle to the information storing element to activate it, retrieving, by the information retrieving section, location information from the information storing element that indicates the vehicle's present position, and controlling a moving direction of the vehicle based on this vehicle's position information.

An apparatus for measuring the concentration of carbon dioxide in water that can correct a reduction in measurement accuracy based on deterioration of a pH indicator is provided. A carbon dioxide concentration measurement apparatus includes a deterioration determining section that measures a change rate ΔA0 of an isosbestic point absorbance A0 and determines that the pH indicator solution is deteriorated when the change rate ΔA0 is reduced by a predetermined reduction rate or more. After the deterioration determining section determines deterioration of the pH indicator solution, a pH value computing section computes the pH value of the pH indicator solution using a corrected pH computation expression for correcting a deterioration of the pH value of the pH indicator solution on the basis of the change rate ΔA0 of the isosbestic point absorbance A0.

A kinetic-energy absorbing member absorbs the kinetic energy of a pull-in member such as a buckle or a lap anchor when reaching a bottom position. The kinetic-energy absorbing member, which includes a thin-walled tubular member that may be made of metal such as iron or aluminum, is arranged between a bracket and buckle. As the pretensioner is actuated, the buckle is pulled by a wire, thereby depressing the kinetic-energy absorbing member against the bracket so that the kinetic-energy absorbing member collapses and the kinetic energy of the buckle is absorbed when reaching the bottom position.

A seat belt device including a shock absorbing mechanism to gently stop a pull-in member and to prevent a large impact force from being exerted on the pull-in member when the pull-in member is pulled in by a pre-tensioner. The device may include a wire pulled by operation of a buckle pre-tensioner at the time of an emergency, a buckle is pulled in towards a bracket while a cover contracts. Before the cover contracts to a maximum permissible contraction position, the buckle comes into contact with the free end of a shock absorbing member, and, then, is pulled in while the shock absorbing member is caused to contract. By the contraction of the shock absorbing member, the shock absorbing member absorbs impact energy of the buckle.

In a single lens reflex camera having a reflecting mirror provided across the light path of a light beam travelling toward a film surface past the stop of a phototaking lens so as to be retractable from the light path, an apparatus for driving the stop device of the phototaking lens for the control of the stop to a predetermined aperture value and the reflecting mirror in relation to the exposure to the film surface includes stop-down operating means capable of being coupled to the stop device and displaceable between a first position for providing a maximum aperture opening to said stop and a second position for providing a minimum aperture diameter to said stop, moving means having a first moving area capable of moving forward while imparting the displacement from the first position to the second position to the stop-down operating means and moving backward while imparting the displacement from the second position to the first position to the stop-down operating means and a second moving area continuous to the first moving area and capable of moving while maintaining the stop-down operating means in the second position, and drive means for moving the moving means forward in the first moving area before the exposure to the film surface and subsequently moving the moving means in the second area. The drive means includes means for driving the reflecting mirror for said retraction while the moving means is in the second moving area.
摘要:
A portion of the driving force for the aperture control apparatus is used to accumulate mechanical energy as required to drive a certain particularly selected device which is to be operated after the operation of the aperture control apparatus. To this end, there is provided mechanical energy accumulation means connected to the driving source. As the result of the work of the mechanical energy accumulation, the speed of the displacement mechanism is reduced.
