The present invention is directed to a tool having a wrist mechanism that provides pitch and yaw rotation in such a way that the tool has no singularity in roll, pitch, and yaw. A positively positionable multi-disk wrist mechanism includes a plurality of disks or vertebrae stacked in series. Each vertebra is configured to rotate in pitch or in yaw with respect to each neighboring vertebra. Actuation cables are used to manipulate and control movement of the vertebrae. In specific embodiments, some of the cables are distal cables that extend from a proximal vertebra through one or more intermediate vertebrae to a distal vertebra, while the remaining cables are medial cables that extend from the proximal vertebra to one or more of the intermediate vertebrae. The cables are actuated by a pivoted plate cable actuator mechanism. In specific embodiments, the actuator mechanism includes a plurality of small radius holes or grooves for receiving the medial cables and a plurality of large radius holes or grooves for receiving the distal cables. The holes or grooves restrain the medial cables to a small radius of motion and the distal cables to a large radius of motion, so that the medial cables to the medial vertebra move only a fraction of the amount as the distal cables to the distal vertebra, so as to achieve precise control and manipulation of the vertebrae.

A swirling bathing tub includes a bathing tub, a water ejecting device mounted on an inner side face of the bathing tub and having at least one water outlet defined in the casing and a water inlet for connection with a water source, a water pump mounted inside the casing and having a water inflow pipe in communication with the water inlet and a water outflow pipe corresponding to the at least one water outlet, a baffle rotatably mounted inside the casing and having at least one through hole corresponding to the at least one water outlet so that water flowing through the water outflow pipe of the pump is able to selectively flow to the bathing tub to create a soothing massaging effect to the user.

A leakage detection circuit for an electric vehicle includes a battery pack, first and second leakage detection switches, a controller, a leakage detection resistor, a voltage detector, and a calculator. The first and second leakage detection switches are connected to the high and low voltage sides of the battery pack, respectively. The battery pack includes a plurality of batteries that are connected in series. The midpoint of the leakage detection resistor is connected to the ground via the first and second leakage detection switches. The controller alternately turns the first and second leakage detection switches ON. Thus, the voltage detector detects leakage voltage values that are generated in the leakage detection resistor. The controller turns the first and second leakage detection switches ON and OFF, respectively, to detect a first leakage voltage value of the leakage voltage values. On the other hand, the controller turning the first and second leakage detection switches OFF and ON, respectively, to detect a second leakage voltage value of the leakage voltage values. Consequently, the calculator detects leakage based on the first and second leakage voltage values.

A drain water bacteriostatic structure for an air conditioner is provided with a drain pan 8 for holding drain water generated in an air conditioner 1 and an upright antibacterial member 50 which is provided in the drain pan 8. The antibacterial member 50 is provided with an antibacterial agent 50B. The length L3 of the antibacterial member 50 in the up-down direction is set such that the lower end portion 50a of the antibacterial member 50 is immersed in drain water when the drain water is at the minimum water level L1 in the drain pan 8, and the upper end portion 50b of the antibacterial member 50 is exposed above the maximum water level L2 of drain water in the drain pan 8 by a predetermined length H or more.
