Abstract: A highly elastic shoe sole comprises a lower layer, an upper layer, and a flexible cushion sandwiched between the lower layer and the upper layer. The lower layer is provided with a plurality of containers for holding compression springs serving to provide the shoe sole with elastic force. The upper layer of a soft material serves to provide a shoe wearer with a wearing comfort. The flexible cushion of a corrugated construction is provided in the underside thereof with a plurality of grooved portions and ridged portions corresponding in location to the containers of the lower layer.

Abstract: An amusement footwear comprises an insole, an outsole, and a resilient portion disposed between the insole and the outsole for providing the footwear with a bouncing effect. The resilient portion comprises a plurality of coil springs which are held securely by the fitting portions of the insole and the outsole and are enclosed by a resilient casing fastened between the insole and the outsole. The insole is provided on the heel portion thereof with an adjustment device for adjusting the size of the footwear. The outsole is provided respectively on the undersides of both front and rear ends thereof with an anti-skidding device. The footwear is provided with a front foot-fastening strap held in the front retaining holes of a ring portion of the insole and is further provided with a rear foot-fastening strap held in the rear retaining holes of the ring portion of the insole and the retaining holes of the adjustment device.

Abstract: An off state demonstrating device on a line-pulling switch for a ceiling fan, is characterized in that a display or demonstrating device is jumper connected at the off position of the switch, so that when the switch is in an off state, the display or demonstrating device can be turned on and a user can be advised that the ceiling fan is in an off state.

Abstract: A play ball has visually distinctive colored patches distributed over its exterior. Portions of the ball exterior may be uncovered with patches, and have a color distinct from the color of patches. Regions of different tactile patterns are impressed on the ball, and these regions may match all or parts of differently colored patches.

Abstract: The improvement of a remotely controlled ceiling fan is achieved mainly by means of a function control IC communicating with TRIAC Q.sub.8, TRIAC Q.sub.9 and TRIAC Q.sub.10 of the speed-changing device via lines Q.sub.5, Q.sub.6 and Q.sub.7 connecting respectively with points 11, 12 and 13 of the function control IC, so as to transmit a command from the function control to the speed-changing device which in turn controls the speed of motor. The function control IC is additionally provided at point 16 thereof with a delay device, which in turn is connected to a relay via line Q.sub.11. The primary line coil of the motor communicates with the relay intended to initiate a change in the polarity of the primary line coil of motor at the time when the function control IC receives a command to put the operation of motor in reverse and the speed-changing device is halted temporarily.
