Abstract:
A circuit board device, a wiring board connecting method, and a circuit board module device are provided for controlling a compression ratio of anisotropically conductive members within an optimal range, for restraining variations in the impact resilient force of the anisotropically conductive members even if an increased number of wiring boards are laminated, for restraining deformations of the wiring board and fluctuations in the impact resilient force of the anisotropically conductive members even if a static external force or the like is applied, for suppressing a linear expansion of the anisotropically conductive members, even if the ambient temperature changes, to increase the stability of electric connections, and for reducing the impact resilient force of the anisotropically conductive members to allow for a reduction in thickness. The circuit board device comprises wiring boards 101-104, anisotropically conductive members 105 placed between the individual wiring boards, functional blocks 106 separate from anisotropically conductive members 105 and are placed on the same plane as anisotropically conductive members 105 so as to enclose anisotropically conductive members 105, and a pair of holding blocks 107, 108 placed to sandwich wiring boards 101-104. These wiring boards 101-104 are kept compressed while they are clamped between pair of holding blocks 107, 108, so that they are electrically connected with each other by anisotropically conductive members 105.

Abstract:
A battery charger is configured to use selective one of two or more power supplies including a commercial AC power supply and a DC power supply. An AC cable is fixedly secured to the body of the battery charger and a DC cable is detachably connected to the body of the battery charger. A single transformer is employed that has a first primary winding to which the AC power supply is connected a first switching element, a second primary winding to which the DC power supply is connected via a second switching element, and a secondary winding to which a battery pack to be charged is coupled.
Abstract:
In a charging device, a driving power supply circuit for driving a control circuit is formed as a separate system from a first power supply circuit, regardless of whether the first power supply circuit is in a driving state or a non-driving state. A microcomputer alternately and intermittently controls the first power supply circuit in the driving state or the non-driving state when the battery pack is not mounted in the charging device in order to reduce the potential difference between the battery pack and the output voltage of the first power supply circuit, thereby avoiding an excessive discharge current from the battery pack when the battery pack is mounted in the charging device.

Abstract:
A liquid medicine ejection device for ejecting a liquid medicine as liquid droplets to be inhaled by a user includes means for providing information on the ejection to the user without providing means for determining a state of the ejection when a preliminary ejection operation is carried out, the preliminary ejection operation ejecting an amount of the liquid medicine smaller than an amount ordinarily ejected. The liquid medicine ejection device enables improved reliability of ejection and comfort of a user by carrying out preliminary ejection before inhalation and by making it possible for the user to visually or auditorily check an ejection state of minute liquid droplets with a relatively simple structure to see whether or not the preliminary ejection is carried out correctly.
