摘要:
An improved high frequency heating apparatus of a type having a drawer-type door assembly together with a turn-table driven from the exterior of a heating chamber and also a support shelf therefor, which is so arranged that the stroke of the door assembly for closing and opening may be set irrespective of depth of the heating chamber, with the positional relation between the turn-table and bottom wall of the heating chamber being accurately maintained during driving of the turn-table.

A microwave oven has an oven-defining housing structure having an electric lamp used to illuminate the interior of the oven-defining housing structure, that is, a heating chamber. The oven-defining housing structure has a control panel at the front thereof, which control panel includes one or more signaling windows or indicators to be illuminated, for example, one signaling window representing, when illuminated, that the high frequency wave generator is in position to generate a low radiating energy into the heating chamber and the other signaling window representing, when illuminated, that the high frequency wave generator is being operated. These signaling windows are respectively illuminated by portions of rays of light emitted by the oven lamp by means of light transmitters. Respective shutter mechanisms are provided for controlling passage of the light rays from the oven lamp towards the signaling windows so that the latter can be illuminated at required times.

A microwave oven comprises a timer for setting a cooking time period, a cooking menu selector with a scale indicating an optimum heating time period for each type of food and quantity thereof and a high frequency output selection switch linked to the cooking menu selector or operated manually. By operating the cooking menu selector to select a corresponding scale for the food to be cooked and setting the timer to a quantity of the food marked on the selected scale, an optimum heating time period may be set, and at the same time the high frequency output selection switch is actuated in a linked relation with the cooking menu selector or manually to select a high frequency output which is optimum to the type of food to be cooked. An output indicator for indicating the selection of the high frequency output is also provided in linked relation to the high frequency output selection switch. By the use of a simple and inexpensive structure of the cooking menu selector and the high frequency output selection switch linked thereto, optimum cooking for the type of food and the quantity thereof including cooking of eggs and defrosting of frozen foods is attained in a simple operation.
摘要:
A cooking device with one cooking or heating chamber in which food may be heated by either one or both of high-frequency heating means and the resistance heating means. The high-frequency or microwave energy is radiated into the heating chamber from the top while the air heated to high temperatures by the resistance heating means disposed within a rear chamber defined back of the rear wall of the heating chamber is circulated therethrough by a circulation fan. Food charges are placed on a receptacle which in turn is placed on a turntable, whereby the food charges may be uniformly heated. The simultaneous use of both the high frequency heating means and the resistance heating means may enable a more wide variety of food to be cooked by a more wide variety of methods.

Sustained release microparticles suitable for various types of drugs, or drug-containing sustained release microparticles capable of sustained release of drugs over a period of three days or more and capable of inhibiting initial burst release; a process for producing the same; and preparations containing the microparticles are disclosed. The drug-containing sustained release microparticles comprise a drug other than human growth hormone and a porous apatite derivative, and optionally include a water-soluble bivalent metal compound. The drug-containing sustained release microparticles can be produced by dispersing under agitation microparticles of a porous apatite derivative in an aqueous solution containing a drug so that the aqueous solution infiltrates into the porous apatite derivative; optionally adding an aqueous solution containing a water-soluble bivalent metal compound that may infiltrate into the porous apatite derivative; further adding additives such as a stabilizer to the mixture; and effecting lyophilization or vacuum drying.

This invention relates to a method for cartilage tissue engineering using scaffolds in simulated microgravity culture. This invention enables engineering of homogeneous cartilage tissue using bone marrow cells in a more rapid manner in a simulated microgravity environment, while allowing control of the configuration of the resulting cartilage tissue.
摘要:
The crosslinking agents and condensing agents that have been employed in biological adhesives and in treating medical devices such as cardiac valves are non-natural compounds synthesized artificially. Thus, they are not metabolized in vivo and exhibit toxicity to living bodies. These compounds are thus used only in a restricted amount and for limited purposes in the clinical sites. The present invention provides a biological low-molecular-weight derivative obtained by modifying carboxyl groups of a biological low-molecular-weight compound with N-hydroxysuccinimide, N-hydroxysulfosuccinimide, or a derivative thereof and a crosslinked high-molecular-weight product obtained by crosslinking various high-molecular-weight compounds with this derivative.
摘要:
A method for producing a porous body comprising apatite/collagen composite fibers comprising the steps of gelling a dispersion comprising long apatite/collagen composite fibers having an average length of 10-75 mm, short apatite/collagen composite fibers having an average length of 0.05-1 mm, and a liquid; freezing and drying the resultant gel to form a porous body; and cross-linking collagen in the porous body.
