Abstract: A ball remover for removing a caput ball from a taper on a stem projecting from a body part of a prosthetic hip joint in the medullary cavity of the femur, comprises a handle to which an operator applies force to remove the caput ball, and a bend part extending in the medial direction at the lower end of the handle. The bend part has a forked end to accommodate the stem. A lower surface on the lateral side of the bend part remote from the median plane abuts the upper surface of a shoulder at the boundary between the body part and the stem. An upper surface of the forked end of the bend part abuts a partially flat lower surface of the caput ball and/or a surface of a lower hemisphere region of the caput ball.

Abstract: A biological signal measurement system includes: a biological signal measurer that measures a biological signal including external noise of biological noise and of environmental noise; biological noise measurer that measures a signal including the biological noise; a biological noise estimator that estimates the biological noise from the signal measured by the biological noise measurer; an environmental noise measurer that measures a signal including the environmental noise; an environmental noise estimator that estimates the environmental noise from the signal measured by the environmental noise measurer; and a calculator that calculates the biological signal in consideration of an effect of the external noise using the signal measured by the biological signal measurer, the biological noise estimated by the biological noise estimator and the environmental noise estimated by the environmental noise estimator.

Abstract: Communication becomes impossible for many mobile stations when a communication failure occurs in a fixed station while the mobile stations are operating in an infrastructure mode. Provided is a communication system that includes a plurality of mobile stations and at least one of a base station and a wireless LAN access point, wherein the plurality of mobile stations establish communication with each other and form an ad hoc network that realizes a mesh network topology, and at least one mobile station among the plurality of mobile stations establishes communication with at least one of the base station and the wireless LAN access point, and connects another mobile station among the plurality of mobile stations to the at least one of the base station and the wireless LAN access point using a tethering function.

Abstract: An object of the present invention is to provide an image display apparatus that suppresses the load on the CPU and the internal storage and suppresses an increase in stress to the user. The image display apparatus of the present invention includes a display, an internal storage, an interface connectable to an external storage, a receiver, and a controller. The external storage stores at least one piece of image data and at least one piece of thumbnail image data obtained by reducing the image data. The controller switches between a thumbnail display mode in which thumbnail image data transferred from the external storage to the internal storage is displayed on the display and a full screen display mode in which original image data of thumbnail image data is transferred from the external storage to the internal storage and displayed on the display, on the basis of inputs to the receiver.

Abstract: A projection positioned in the center of a concave section of a toroidal combustion chamber is divided into a section with a steep slope extending from the bottom to the head surface and a section with a gentle slope. The head surface is in the form of a flattened conical trapezoid. Because of its shape, the projection makes it possible for the air which is close to the center section to flow close to the surface of a side wall of the concave section. The air which had been at the center section is added to the amount of air supplied for combustion and is mixed with the fuel in the vicinity of the surface of the side wall of the concave section. By setting the angle at which the air flows along the side wall surface (re-entrant angle) in the combustion chamber, the flow of the air close to the side wall surface is made turbulent, which improves the agitation of the fuel.

Abstract: Variable swirl intake apparatus (24) controls a swirl of intake air in cylinder chamber (22) of an engine.
