摘要:
A microwave oven equipped with a rotary table for placing food material to be cooked thereon in which the rotational center of the rotary table within the heating chamber is offset toward the rear wall of the heating chamber from the central portion of the distance between the inner surface of the door and the rear wall of the heating chamber, that distance being larger than the inner width of the heating cavity for preventing the danger of electric wave leakage resulting from breakage of a shielding plate and its reinforcement in the oven door due to contact of the food material or a spit carrying the food material with such reinforcement and resultant spark discharge.

The object of the present invention is to provide a calcium phosphate-collagen fiber composite which has an excellent mechanical property, can induce bone replacement by rapid bone remodeling, and can be used in a high-load region. The object can be solved by a porous composite comprising a calcium phosphate crystal and a collagen fiber at a weight ratio of 80:20 to 20:80, wherein (1) a bioabsorbability of the porous composite is graded, and (2) the density of the porous composite determined by gravimetric method is 300 to 1500 mg/cm3.
摘要:
A porous composite comprising a porous layer containing a calcium phosphate ceramic, and a dense layer formed on part of the porous layer and having a smaller average pore size than that of the porous layer. The porous composite can be produced by (1) introducing a slurry containing a calcium phosphate ceramic/collagen composite and collagen into a molding die having a high thermal conductivity, (2) rapidly freezing and drying the slurry in the molding die, to form a porous body comprising a porous layer and a dense layer formed on the porous layer, (3) cross-linking collagen in the porous body, and (4) removing the dense layer except for a portion thereof on a surface coming into contact with a soft tissue when implanted in a human body, so that the porous layer is exposed.

Provided is a sustained-release microparticle preparation of a human growth hormone which combines biodegradability with sustained-release performance while avoiding the use of an organic solvent as much as possible, allows the sustained-release of a human growth hormone over 3 days or more and reduction in the initial burst release, can contain a human growth hormone at 10% or more, can quantitatively adsorb and encapsulate a human growth hormone at up to 20%, and has excellent dispersion and needle penetration properties. A process for producing the sustained-release microparticle preparation of a human growth hormone is also provided. The sustained-release microparticle preparation comprises a porous apatite derivative, a human growth hormone, and a water-soluble divalent metal compound.

摘要:
A microwave oven with heater has a wave guide plate between a rotary heater and a wall of a heating chamber on which a bearing for the rotary heater is provided, for controlling microwave to improve distribution thereof, and further, preventing adhesion of scattered food thereby to maintain insulation between the heating chamber on the rotary heater.
摘要:
A composite heating apparatus provided with means for both high frequency dielectric heating and resistance heating. At the start of cooking, all the input power is supplied to the heater to accelerate the rise of the temperature in the heating chamber, and the power input to the heater is automatically controlled when the temperature in the heating chamber reaches a predetermined temperature to maintain the temperature in the heating chamber constant. At the same time, the high frequency generator is operated at comparatively low output. This makes possible the simultaneous cooking by dielectric and resistance heating even in areas not favored with a satisfactory power supply situation on the one hand and, on the other hand, is expected to contribute to energy saving in areas favored with a satisfactory power supply condition.
摘要:
A microwave heating apparatus has a body with a front wall, and a heating chamber within the body for holding an object to be heated. A microwave source is provided for generating microwaves, and a wave guide is connected between the microwave source and a microwave inlet for guiding the microwaves from the microwave source to the heating chamber. A radiant energy heater is disposed within the heating chamber for heating the object to be heated by radiant energy, and a power box is positioned above the chamber and housing the microwave source and the high voltage circuit components therefor. A microwave source cooling fan is provided in the power box, and thermal insulation covers the walls of the heating chamber, the upper surface of the thermal insulation on the top of the chamber and the bottom surface of the power box being spaced to provide a cooling conduit. The front wall of the body has an air suction inlet therein opening into one end of the cooling conduit, and a power box cooling fan is provided at the other end of the cooling conduit. The power box has a suction port therein opening into the cooling conduit upstream of the power box cooling fan for admitting air from the cooling conduit into the power box, the microwave source cooling fan and the power box cooling fan being in parallel flow relation.
