Abstract: A clothes hanger which includes a sleeve having two vertically spaced coupling slots, a toy doll covered around the sleeve and having a through hole, a hanging bar coupled to the bottom end of the sleeve, a sliding shaft supported on a spring inside the sleeve and moved in and out of the through hole of the toy doll, an end cap fastened to the top end of the sleeve to hold down the periphery of the through hole of the toy doll, a swivel hook coupled to the top end of the shaft and moved with the shaft in and out of a pocket at the top of the toy doll, the shaft having a springy strip with a raised coupling portion adapted for engaging one of the coupling slots to hold the hook in or out of the pocket of the toy doll.

Abstract: A cooking device having an outer pot and an inner pot removally suspended in the outer pot is proposed for better and easier cooking of foodstuff. The inner pot is made of thermally conductive, metallic material and is adapted for initially cooking foodstuff with a separate heater for a short period of time. The outer pot is made into a thermally insulated construction and adapted to house the inner pot containing the semi-cooked foodstuff in the outer pot in a thermally insulated manner, so as to allow the semi-cooked foodstuff to complete the cooking by its own latent heat without a further heating by an external heat supply means.

Abstract: A speed adjusting mechanism for adjusting the speed of an endless belt of a treadmill includes a speed variable V-belt drive mechanism which has two pairs of cone-shaped discs mounted coaxially on a transmission shaft disposed between an output shaft of a motor and a driven shaft of the treadmill belt. Each pair of discs includes a fixed disc and a slideable disc adjacent to the slideable disc of the other pair of discs, and the slideable discs slide mutually upon lateral displacement of the transmission shaft. The transmission shaft is displaced laterally by a reversible motor through a crank mechanism and a gear mechanism including a sector gear. The slope of the belt is adjusted by another reversible motor through a gear mechanism including a sector gear.
