Abstract: A vehicle door lock device, including: a latch unit provided at a vehicle door, selectively adopting an unlatched state in which the vehicle door can be opened, or a latched state in which the vehicle door is maintained in a closed state, and transitioning from the unlatched state to the latched state in a case, in the unlatched state, in which the vehicle door is closed relative to the vehicle body; a mechanical operation unit switching the latch unit from the latched state to the unlatched state by means of at least one of operative parts being operated; an electrical operation unit connected to the mechanical operation unit, and switching the latch unit to the latched state or to the unlatched state, by means of power from a drive unit; and a cancellation unit that releases the connection between the electrical operation unit and the mechanical operation unit.

Abstract: A leisure boat is provided in a round form having a diameter of about 1 to 2 meters, and includes propeller means provided at a position closer to its bow from the center of the boat and the bow and having a mechanism for changing its driving direction and sensor means provided on the outside of the boat for sensing external force. The sensor means is so connected to the propeller means that when the boat comes in contact or collision with another boat, etc., the sensor means detects the resulting external force to transmit it to the propeller means, thereby changing its driving direction.

Abstract: A roller element for a slide comprising an outer cylinder, an inner pipe and connector members for making connections therebetween all integrally formed of a material having a suitable elasticity, wear resistance, weather resistance, etc. wherein the outer cylinder has a thickness sufficient to make it deformable, and stopper slightly shorter than the space formed between the outer cylinder and the inner pipe are provided to limit the amount of deformation of the outer cylinder, alternatively ribs for connector members which are connected to the outer cylinder and inner pipe on a reduced-diameter side of the outer cylinder, and connected to the inner pipe alone on an increased-diameter side of the outer cylinder to form a gap of about 2-3 mm between the outer edge of the inner pipe and the inner face of the outer cylinder.

Abstract: A water slider lane includes a sliding surface the effective portion of which has a width larger than the diameter of a sliding boat. The sliding surface is bent or tilted down toward one side, thereby moving a sliding boat toward a turning zone. A region of the sliding surface, at which the sliding boat approaches the turning zone, is tilted up to form an upward slope, and the upward slope is connected at its upper edge and through a bend to a side wall of the lane, whereby the sliding boat goes up the upward slope to such a degree that its upper portion goes slightly beyond the upper edge of the upward slope. When the sliding surface has its effective portion's width smaller than the diameter of a sliding boat, a step in the form of a ridge and others may be provided on the sliding surface.

Abstract: A bearing case for a roller slide comprises a casing, an arm, a stopper formed on the casing and a pawl retainer formed around the outer edge of an end of the arm, which are all formed of a tough material by integral molding. The casing for receiving a bearing comprises a drum, an inner lid and an outer lid and has a depth virtually equal to the thickness of the bearing and an inner diameter virtually equal to the outer diameter of the bearing, and the arm has an outer diameter virtually equal to the diameter of a hole in which the bearing is built.
