摘要： A heat exchanger has plural flat tubes through which refrigerant flows, and a pair of header tanks disposed on each longitudinal ends of the flat tubes. Each of the flat tubes has a flow passage portion having plural flow passages through which refrigerant flows, and a non-flow passage portion disposed on both sides of the flow passage portion, having at least one non-flow passage through which no refrigerant flows. The flow passage portion is inserted into the header tank so that the flow passages communicate with the header tank, and the non-flow passage portion is exposed outside the header tank. Each of the flow passages has a circular-shaped cross-section while the non-flow passage has a polygonal-shaped cross-section, so that a wall thickness of the non-flow passage is made thinner than that of the flow passages. Therefore, weight of the flat tube is decreased, while sufficient strength thereof is maintained. On the other hand, the header tank has an inner partition wall for partitioning the header tank into first and second tank passages having an oval-shaped cross-section, so that the header tank has high pressure resistance.

摘要： A Mn—Zn ferrite having large electrical resistance, which can withstand use in high frequency region exceeding 1 MHz, is provided. The Mn—Zn ferrite comprises the following basic components: 44.0 to 50.0 mol % Fe2O3, 4.0 to 26.5 mol % ZnO, 0.1 to 8.0 mol % at least one member selected from the group consisting of TiO2 and SnO2, and the remainder being MnO. By the addition of TiO2 and SnO2, even if the material is sintered in air, electrical resistance of 103 times that of the conventional Mn—Zn ferrite can be obtained, and high initial permeability of 300 to 400 as estimated can be secured even at high frequency of 5 MHz.

摘要： Various signals are exchanged between a coin acceptor section that identifies the authenticity of deposited coins and sorts out the on the basis of their denominations, and a change control section that receives the sorted-out coins and performs control to count the coins and to deliver the coins as a change. Such a signal exchange between the two sections is achieved through optical coupling between a light emitting diode and a photo transistor, without employing any electric contacts. Further, electric power supply from the change control section to the coin acceptor section is done through spring-biased probes without employing any electric connectors, or through inductive coupling without employing any electric contacts. Such arrangements can greatly facilitate attachment and detachment of the coin acceptor section to and from the change control section.

摘要： A high-performance R--Fe--B permanent magnet being radially anisotropic can be produced by carrying out hot bending of a plateshaped magnet material produced by casting and hot working, to mold it into an arc shape; the cracks to be generated during the bending can be decreased by deciding such bending conditions as the amount of strain, the strain rate, the working temperature, as well as the structure and the composition of the alloy. Furthermore, by optimizing the conditions for heat-treatment and by using an oxidation resistance coating lubricant, an arc shape magnet of high performance and a low cost can be produced under stabilized conditions.

摘要： The delta-sigma modulator includes a secondary delta-sigma modulator which carries out a secondary delta-sigma modulation for an analog input signal, thereby producing a first quantization signal. A quantization noise extractor extracts a quantization noise occurring in the secondary delta-sigma modulator. A primary delta-sigma modulator carries out a first delta-sigma modulator for the quantization noise, thereby producing a second quantization signal. A differentiating circuit differentiates the second quantization signal supplied from the primary delta-sigma modulator. An adder adds the first quantization signal and an output signal of the differentiating circuit, thereby producing a digital output signal corresponding to the analog input signal.
