Abstract: A composite heat exchanger having functions of air cooling and spray cooling, includes two base plates, a fin group between the base plates, and a flow conduit. The fin group includes a plurality of fins. Each fin is defined with a plurality of receiving holes. The flow conduit parallelly extends through the receiving holes and surrounds an outside of the fins whereby the outside surface of the flow conduit surrounding the fins directly contacts atomized heat exchange media for heat transfer through phase change.

Abstract: An auxiliary device for a hot water device includes a compressor, a condenser, a drier, an expansion valve, an auxiliary system, and an evaporator. The auxiliary system is connected with the evaporator as integral, and heat source is sent into a pipe route of the auxiliary system by a pump. So when lower pressure gas coolant is evaporated in the evaporator, the coolant is heated by the heat source in the pipe route of the auxiliary system. The coolant is in advance heated, so the compressor can reduce electricity for raising the temperature of the coolant. The auxiliary device can be operated regardless of weather condition.

Abstract: A manufacturing method of an electronic diaper is to provide a sensor feeding band or box supplying a diaper body with a sensor which will be in advance attached on the upper or the lower dry layer of the diaper body for carrying out a sequent process of automatically manufacturing an electronic diaper. The electronic diaper includes an upper and lower dry layer and an sbsorbing layer sandwiched between the two dry layers, a sensor attached on the upper or the lower dry layer. The sensor has a connecting member for connecting with a controller. Sensing the diaper body wetted, the sensor will give a signal to the controller which will immediately give out warning signals to remind a nurse that the diaper is wet and needs to be replaced with a new one so that a user may feel comfortable in using the electronic diaper.

Abstract: A method of forming a mask for bombardment of a semiconductor substrate with high energy particles and a mask formed thereby are provided. A patterned layer of a blocking material is formed over a mask substrate to define a high energy particle bombardment mask pattern. The blocking material has sufficient thickness in the mask pattern to substantially shield the semiconductor substrate from selected high energy particles in areas overlapped by the mask pattern when the mask is aligned over the semiconductor substrate. The mask includes a mask substrate having a patterned layer of blocking material formed thereon to define a high energy particle bombardment mask pattern. The blocking material has sufficient thickness in the mask pattern to substantially shield the semiconductor substrate from selected high energy particles in areas of the semiconductor substrate overlapped by the mask pattern when the mask is aligned over the semiconductor substrate.

Abstract: A capacitive position transducer for detecting position changes or producing position feedback signals in a servorecorder comprises a rhombic transmitter electrode connected to a voltage source and a plurality of rectangular receiver electrodes insulated from and adjacent to each other. Current flowing through the coupled transmitter and receiver electrodes is rectified by diode circuits and flows through a circuit of serially connected resistors, thereby forming an output voltage signal at an end of the resistor circuit. The linearity of the output voltage signal can be changed by changing the value of the resistors in the resistor circuit. The capacitive position transducer can also provide commutating signals required by brushless linear motor.
