Abstract:
An ice cube maker has an ice tray, a thermoelectric cooling chip, a heat sink and a fan sequentially mounted together. The ice tray has a top surface and multiple recesses formed in the top surface. When liquid is placed in the recesses in the ice tray, the thermoelectric cooling chip freezes the liquid and forms ice cubes. The ice cube maker allows people who do have a refrigerator to make ice cubes. The ice cubes do not have any strange smell.
Abstract:
A flavored ice on a stick maker has an insulated housing, an ice tray and at least one thermoelectric cooling assembly. The ice tray is mounted inside the insulated housing and has multiple mold recesses formed in the ice tray and multiple ice molds respectively mounted in the mold recesses. The thermoelectric cooling assembly is mounted in the insulated housing against the ice tray. Juice and sticks put into the ice mold, and the thermoelectric cooling assembly freezes the juice in the ice molds to form flavored ice on a stick. The flavored ice on a stick can be any flavor, and the flavored ice on a stick maker allows people who do not have a large enough freezer to make flavored ice on a stick. The flavored ice on a stick does not have any strange smell.
Abstract:
A solid electrolyte dual gas sensor 10 is made, containing a container body of a first solid electrolyte 11, in contact with a monitor electrode 17 exposed to a monitored gas environment 13 containing selected gas components to be measured, and in contact with a reference electrode 15 which is additionally isolated from the monitored gas environment by a second solid electrolyte 16, and optionally 14, where the second solid electrolyte, at the operating temperature of the gas sensor, is effective to dissociate to provide the sole source of self-generated gases at the reference electrode 15, corresponding to the selected gas components to be measured in the monitored gas environment, where, at the operating temperature of the sensor, the first solid electrolyte 11 is effective to conduct oxygen ions, and the second solid electrolyte 16 is effective to conduct ions selected from the group of sodium ions, potassium ions, and their mixtures.
Abstract:
An alkali ion conductive solid electrolyte electrochemical concentration cell assembly for measuring gases containing anhydrides or related compounds in air or in oxygen-bearing gases is divided into two identical alkali ion conductive half cycles. Each half cell is secured to opposite surfaces of the closed end of a solid membrane exhibiting alkali ion conductivity corresponding to the alkali ion conductivity of the half cells. The membrane effectively isolates a monitored gas environment contacting one half cell from a reference gas environment contacting the other half cell while supporting the equilibrium mode of operation of the concentration cell assembly to generate an electrical signal indicative of a gas species of interest in the monitored gas environment.
Abstract:
The present invention discloses an apparatus for thin-layer cell smear preparation and in-situ hybridization, comprising at least one positioning device and a sealing device. The positioning device comprises at least one first opening. When the positioning device is set on a carrier device, the wall of the first opening and the carrier device form a cavity. The cavity is used to accommodate a cell suspension. The sealing device is provided on the positioning device for sealing the cavity to form an enclosed space.
Abstract:
The present invention discloses a sanitary utensil with functions of immuno-chromatographic test and indication, which comprises at least one immuno-chromatographic test piece and at least one cover having an open end. The immuno-chromatographic test piece further comprises a test starting portion, an indicating portion and a test stopping portion. Furthermore, the cover is used to protect the test stopping portion, the indicating portion and part of the test starting portion, so that the bio-specimen is allowed to enter the immuno-chromatographic testing piece only from the test starting portion.
Abstract:
The present invention discloses a dehydration and preservation method for a sanitary utensil containing bio-specimen. First, a closed system for storing the sanitary utensil containing bio-specimen is provided. Next, a drying agent is provided in the closed system to remove the water vapor evolved from the bio-specimen. Additionally, a deodorization agent can be provided in the closed system to absorb the smell of the bio-specimen. Moreover, this invention also discloses several storage devices for storing a sanitary utensil containing bio-specimen.
Abstract:
A refrigerator includes a hollow casing, an insulation layer securely attached to an inner side thereof, a freezer area defined in the casing and in communication with the opening of the casing, a refrigeration area defined in the casing and separated from the freezer area by a baffle. The refrigeration area is in communication with the opening. A first conductor and a second conductor are sandwiched between the baffle and the insulation layer. A thermoelectric cooling chip is selectively actuated for reducing and increasing air temperature. A first heat dissipation device is provided to dissipate heat from the thermoelectric cooling chip, such that heat conduction between the first conductor and the second conductor is able to conduct cold air from the thermoelectric cooling chip to the refrigeration area and the freezer area.
Abstract:
A mobile communication device. The mobile communication device comprises a main body and a speaker selectively projected from the main body and inserted into user's ear to obtain better audio quality.
