Balloon catheter

A balloon catheter in which a high-frequency current is supplied between electrodes spaced in a balloon, the liquid in the balloon is heated, and the heat conducted through the balloon ablates the organism tissue in contact with the balloon, characterized in that the area of the surface of each electrode is 20 mm2 or more or a potential detecting electrode for detecting the potential at an abrasion portion is disposed outside the balloon and in a position at least before or behind the balloon.

Plasma processing apparatus and mounting unit thereof

A parallel plate type plasma processing apparatus including a RF feed rod for applying a high frequency power to a susceptor and a temperature detection unit for detecting the temperature of a substrate on the susceptor is configured to reduce an effect that high frequency current flowing in the RF feed rod has on temperature detection of the temperature detection unit. A surface portion of the susceptor serves as a mounting unit including an electrostatic chuck and a heater. A shaft, which is a protection pipe extracted downward from the processing chamber, is provided under the mounting unit. A chuck electrode of the electrostatic chuck serves as an electrode for applying a high frequency voltage. Provided in the shaft are two RF feed rod for supplying a power to the electrode and an optical fiber, i.e., a temperature detection unit, having a dielectric fluorescent material is disposed in a leading end thereof. Then, the two RF feed rods and bar type conductive leads for the heater are alternately arranged at equal intervals in a circumferential direction on a circle having the optical fiber at the center thereof such that the region having therein the optical fiber is an electromagnetic wave-free region since the electric force lines respectively traveling from the RF feed rods to bar type conductive leads are offset with each other.

Electric cooker and control method thereof

The invention provides an electric cooker and a control method thereof. The control method comprises the following steps: after the electric cooker is started, the electric cooker is controlled to be heated at the first average power; when the temperature in the electric cooker reaches a first preset temperature, heating of the electric cooker is controlled to be stopped temporarily; first preset time later, the electric cooker is controlled to be continuously heated at the first average power; when the temperature in the electric cooker reaches a second preset temperature, the electric cooker is controlled to be heated at the second average power, wherein the first preset temperature is larger than the second preset temperature, the power regulation ratio of the second average power is smaller than that of the first average power and the power regulation cycle of the second average power is larger than that of the first average power; when the temperature in the electric cooker reaches a boiling balance temperature point, the electric cooker is controlled to be heated at the third average power so as to keep boiling; and second preset time later, heating of the electric cooker is controlled to be stopped. According to the electric cooker and the control method thereof, the fact that the electric cooker reaches boiling temperature and material in the electric cooker does not overflow can be guaranteed and temperature control is more accurate.

Switching power supply unit

InactiveUS6879132B2Precise managementManage the charging and discharging of the secondary batteryElectrically conductive connectionsSecondary cellsAlternating currentControl circuit
A switching power supply unit which contains a secondary battery for backup and a circuit for controlling the charging and discharging of the secondary battery in its enclosure and which properly manages the charging and discharging of the secondary battery. A switching power supply circuit includes a rectifying and smoothing circuit for smoothing alternating-current input from commercial power supply Vin at normal operation time, a battery pack charged by a DC—DC converter which can continuously output a predetermined direct-current power supply voltage for supplying power supply voltage to the DC—DC converter at the time of a stoppage in alternating-current input, a charging circuit section for controlling the charging and discharging of the battery pack, and a charging and discharging control circuit. The battery pack and circuits, such as the DC—DC converter, are mounted in the same unit enclosure.

Refrigerator and its temperature control method

The invention discloses a refrigerator and its temperature control method. The method comprises the following steps: detecting the current temperature of a variable-temperature chamber; judging whether a difference between a shutdown temperature of the variable-temperature chamber and the current temperature is not lower than a first difference temperature; if yes, detecting an ambient temperature of the refrigerator, and judging whether the ambient temperature is not higher than a preset ambient temperature; and if yes, controlling a temperature compensation heater in a first preset mode to heat the variable-temperature chamber, otherwise controlling the temperature compensation heater to operate in a second preset mode. The refrigerator temperature control method of the inventive embodiment can precisely control the temperature compensation heater to carry out temperature micro-adjustment on the variable-temperature chamber in different modes when the set temperature of the variable-temperature chamber is relatively high (usually used for a refrigerating chamber), to make the temperature of the variable-temperature chamber quickly reach the set temperature, and has advantage of high control accuracy, thus contributing to food storage in the variable-temperature chamber and improving practicability of the refrigerator.

Foodservice product with a PCM

A single use multi-layered food service product such as paper cups, food containers, or sleeves constructed of materials including at least one phase changing material (PCM) with one or more additives to produce a thermal conductivity ratio of at least 2.0 W / mK and a melting point between 45 degrees C. and 80 degrees C. An inventive pattern for the placement and distribution of the PCM within its multilayered walls is described. The PCM is configured in order to minimize manufacturing cost and environmental impact while providing insulation and maximizing its ability to rapidly reduce and then maintain a safe and preferred temperature for served food or beverages.
