Abstract: A mattress comprises an upper layer having a number of projections formed integrally on the top surface thereof and a lower layer, the upper and lower layers being formed of foamed plastic capable of being deformed by compressive load and restored. A hygroscopic layer formed of a highly hygroscopic material such as cotton is disposed under the upper layer to absorb water from the upper layer. Between the hygroscopic layer and the lower layer lies a middle layer which has a number of columnar core members arranged parallel to and coupled with one another. The core members are formed from relatively hard foamed plastic. An outer covering covers the upper, hygroscopic, middle, and lower layers. Upper and lower spaces are defined between the middle and hygroscopic layers and between the middle and lower layers, respectively, and communicate each other. The water absorbed by the hygroscopic layer is discharged into the upper and lower spaces, where it is discharged into the open air through the outer covering.

Abstract: In a tilting health table apparatus, a pair of first handles are horizontally set on both sides of the upper end portion of a leg assembly. A table is swingably fitted to the leg assembly to securely hold the user and the table is securely set in a prescribed position by means of first, second and third stopper mechanisms. A foot board is mounted on one end portion of the table, and a pair of second handles are fitted to both sides of the foot board.

Abstract: An absorption refrigeration system having a generator, a rectifier, a condenser, an evaporator, an absorber and heat exchangers which are connected by means of conduits in an airtight manner so that circulations for refrigerant and for absorbent solution are formed, wherein the rectifier is mounted upright above the generator, and wherein a receiver for receiving absorbent containing refrigerant is mounted below the rectifier and communicates with the lower portion of the generator through an absorbent passage means, whereby decreasing hindrance of the generation of the refrigerant vapor from the generator, thus increasing the efficiency in generating vapor and, at the same time, preventing local overheating of the solution in the generator.

Abstract: Apparatus for chiropractic therapy and massage having a housing on which the user lies, pressure means including a number of pressure rollers disposed in the housing which rolls to apply pressure on the user lying on the housing, a support frame provided in the housing and supporting the pressure roller, a pair of pulleys provided in the housing, and a wire stretched between the pulleys to reciprocate the support frame. The apparatus further comprises a spring coupled to both ends of the wire for absorbing the elongation and contraction of the wire; and first and second interlocking members coupled to both ends of the wire and to the support frame for transmitting the driving force of the wire directly to the support frame without transmitting the driving force to the spring.

Abstract: A cooking apparatus includes a fermenting heater for a vessel which is disposed below the bottom of the vessel and a fermenting heater for an oven chamber which, together with the fermenting heater for the vessel, can be turned ON. A kneading switch, fermenting/baking switch and a release switch for opening these switches are disposed on the front surface of the apparatus housing. Likewise, an exclusive time setter, automatic time setter and baking time setter are disposed on the front surface of the apparatus housing. A kneading circuit, fermenting/baking circuit, kneading/fermenting circuit and fermenting/baking circuit are selectively controlled by selecting a combination of the switches and time setters to perform a kneading step, fermenting step and baking step either singly or in combination.

Abstract: A cooking apparatus comprises an apparatus housing divided by a partition plate into upper and lower chambers. An oven chamber is defined in the lower chamber and has a baking heater therein. A vessel having a kneading blade is disposed on the upper chamber. The upper chamber includes a drive mechanism for rotating the blade. A fermenting heater is provided below the bottom of the vessel to heat the interior of the vessel to a fermenting temperature. Dough is kneaded and fermented in the vessel and baked in the oven chamber. Another fermenting heater is disposed in the oven chamber to preheat the interior of the oven chamber for baking, while the dough is being kneaded and fermented in the vessel.
