Abstract: A robot including one or more joints is configured to, when a particular joint among the joints has not been driven for a predetermined time, move the particular joint such that the robot refrains from coming into contact with a surrounding object or such that the robot comes into contact with the surrounding object while preventing a force applied to the robot from reaching a predetermined level or higher.

Abstract: The urine amount measuring device (100) includes a container-side support portion (10), a sensor (32), a housing (101), a first fixing portion (20), and a second fixing portion (60). The container-side support portion (10) supports the suspension portion (50) on which a urine storage container (C) is hung. The urine storage container (C) stores urine of a person lying on the bed (B). The sensor (32) outputs a signal that changes according to change in force acting on the container-side support portion (10). The housing (101) houses the sensor (32). The first fixing portion (20) fixes a tubular member (T) to the housing (101). The tubular member (T) allows the urine to flow from the person to the urine storage container (C). The second fixing portion (60) fixes the tubular member (T) to the suspension portion (50).

The carrier rotates about its center and moves circularly around the center of the surface plates spaced from the center thereof. The upper surface plate is reciprocated in a direction perpendicular to the central axis when required.

Abstract: An alcohol, e.g. methanol, carbon monoxide and oxygen are allowed to react in a gas phase in the presence of a solid catalyst comprising a catalyst component, for instance, containing halogen and copper atoms supported on a solid support. The alcohol and carbon monoxide contents of the reactor feed gas are controlled at 1 to 20 volume % and 70 to 95 volume %, respectively. Because the alcohol and carbon monoxide contents of the feed reactant gas are thus controlled, side reactions are considerably inhibited and the object carbonic diester is produced with high selectivity.
