Abstract: The present invention relates to a device capable of cooking food products in a short time so as to concentrate the emitted light on the food product using a lamp emitting light in an infrared region. More particularly, it is capable of cooking the food product in a short time by concentrating light in the visible light region within a wavelength range of more than 1.35 &mgr;m on the food product using a luminous unit for emitting light in the infrared light region and a reflecting plate for concentrating the emitted light in the infrared light region.

Abstract: The present invention relates to a microwave oven including a cavity having a certain area for cooking comprising a flow path formed between a main body and the cavity so as to be connected from a side of the cavity to the upper surface of the cavity, a heater installed on the side of the flow path corresponding to the outer upper surface of the cavity for emitting heat, a discharge hole installed on the upper surface of the cavity corresponding to the lower portion of the heater for discharging the heat of the heater into the cavity, an inlet installed on the lower portion of the side wall of the cavity for making the air inside of the cavity flow in the flow channel, and a circulating fan installed on a certain portion of the flow channel for circulating the air inside of the cavity flown through the inlet to the heater.

Abstract: Disclosed herein are a novel strain of Streptomyces and a method for the production of aclacinomycins A, B, Y and aglycone thereof by cultivating the same. Streptomyces lavendofoliae DKRS(KCTC 0092BP) of the present invention is capable of producing aclacinomycins A, B, Y and aglycone with higher yield. Further, it is possible to selectively produce aclacinomycin A or Y by adjusting pH of the cultured broth of Streptomyces lavendofoliae DKRS to 4.4 or 4.6 with acetate buffer or hydrochloric acid, respectively.

Abstract: An air conditioner has a flow directing vent comprised of slanted vanes. The vent is driven by a drive mechanism which oscillates the vent about an axis. The drive mechanism includes a motor driven shaft which rotates continuously in one direction, and a mechanism for converting such continuous rotation into oscillation of the vent. The drive connection between the vent and drive mechanism can be manually disconnected by axial displacement of the vent, to enable the rotational position of the vent to be adjusted relative to the drive mechanism.

Abstract: This invention relates to the process for producing ortho-isopropylated phenol derivatives having following general formula (VIII). ##STR1## (in the above formula, R.sub.1 is a hydrogen or a low alkyl group of C.sub.1 -C.sub.4)A process for producing ortho-isopropylated phenol derivatives (VIII) of the present invention is characterized by obtaining position isomer desired by means of Claisen rearrangement of phenyl allyl ether without catalyst in atmosphere, and then obtaining only one isomer by oxidation and reduction of the above-obtained position isomer. According to the present invention, ortho-alkylated phenol derivatives (VIII) having high purity at low temperature and low pressure can be prepared without producing a by-product and requirement of the complicated separation procedure.

Abstract: A control switch comprises a bellow which contracts and expands pressure of the refrigerant, a lock/unlock member which cooperates with the existence of the pressure of the refrigerant, a spring for forcing the lock/unlock member against the pressure of the bellow, and a rotatable shaft operatively disposed through the lock/unlock member. The lock/unlock member has an unlock slot proximate the bellow, a lock slot distal the bellow, and a tapered transition portion between the unlock slot and the lock slot. The shaft is a polygonal, e.g. hexagonal, which fits into the lock slot when the pressure of the refrigerant is under a predetermined value. The user is made aware of the leakage of the refrigerant by the restriction of the rotation of shaft or a break in the power circuit, or both. This prevents the operation of an inefficient in the air conditioner.

Abstract: Synthesized succinyl and glutaryl glucosamines, p-(succinylamido)-phenyl-.alpha.-D-gluco- and mannopyranosides, p-(glutarylamido)-phenyl-.alpha.-D-gluco- and mannopyranosides and p-(isothiocyanotophenyl)-.alpha.-D-gluco- and mannopyranosides are reacted with insulin to form corresponding glycosylated insulins containing from 1 to 3 glycosyl groups per insulin molecule. The novel glycosylated insulins resist aggregation and show significant activity in depressing blood sugar levels.
