    摘要: A thin electronic calculator having a circuit board unit in which an IC pellet is directly mounted on a film board and allowing easy mass-production is provided. Metal foil leads each having one end and the other end radially extending from the one end and having a larger width than the one end are formed on the film board. The IC pellet is bonded to one end portions of the metal foil leads through bump electrodes. The circuit board unit is fixed to a wiring board by an anisotropically electrical conductive adhesive. The other end of each metal foil lead is electrically connected to a corresponding connecting terminal formed on the wiring board. An electronic component assembly constituted by the circuit board unit and the wiring board is received in upper and lower covers, and is adhered by adhesive islands deposited on the covers.

    摘要: A semiconductor capable of exhibiting an electron transfer effect in a high electric field is used as a Hall element. Application of a voltage large enough to give rise to an electron transfer effect to the current input electrodes of the Hall element brings about a decrease in the concentration of electrons contributing to the Hall effect occurring within the semiconductor, an increase in the Hall coefficient and a notable enhancement in the sensitivity of the Hall element.

    摘要: A vehicle is equipped with a main battery, an auxiliary machinery battery, a high-capacitance DC/DC converter which converts power on an electric path between the main battery and a motor-generator for traveling to supply the converted power to the auxiliary machinery battery, a low-capacitance sub power supply which converts power on an electric path between the main battery and an external power supply to supply the converted power to the auxiliary machinery battery, and a control device which controls the sub power supply. The control device determines whether or not the DC/DC converter has an abnormality, and operates the sub power supply to perform precharging when it is determined that the DC/DC converter is abnormal. An auxiliary machinery battery voltage V2 when precharging has been performed is set to a value which is higher by a predetermined voltage a than an auxiliary machinery battery voltage V1 when precharging has not been performed.
