摘要:
A substrate connecting member connects two circuit boards connected together while maintaining high reliability of the junctions between itself and the circuit boards even if the circuit boards are warped by temperature change of an impact load. The substrate connecting member includes a frame member made of an insulating resin; slit grooves formed in at least one of the inner and outer surfaces of frame side portions composing the frame member, the slit grooves being formed throughout the entire length of the frame side portions in the direction perpendicular to the thickness direction of the frame side portions; and connection conductor portions having connection terminals provided on the top and bottom surfaces, respectively, of the frame side portions in the thickness direction and connecting conductors each connecting connection terminals.

A first circuit board (1) mounted with an electronic component (16) and a second circuit board (2) are vertically connected three-dimensionally through an interconnecting board (3) wherein the terminal portion (6) of the land electrode (5) on the interconnecting board (3) is buried in the termination material (9) of the interconnecting board (3). Consequently, the chance of peeling or cracking due to peeling stress or shearing stress acting between the upper/lower circuit boards and the land electrode by high density mounting, thermal shock or falling impact can be suppressed or buffered resulting in high reliability.

An electronic device is provided which executes a function useful in that place without a user in possession of the electronic device being intentional, and which does not receive a signal without providing a special setting if the function is not useful even if the place and the device are the same. There are an electronic device A and an electronic device each having a human body communication function. In a case where a user is holding the electronic device A, the electronic device B outputs a control signal for causing the electronic device A to execute a function aimed to eliminate a danger or an annoyance to the surroundings occurring because of holding it, whereas, due to the fact that the user has the electronic device, the electronic device A receives the control signal irrespective of the user's intention and executes a function based on the control signal.

A folding type portable telephone in which a first housing and a second housing are fixed by a hinge includes a face panel fixed to the first housing and aromatic substances are accommodated inside the face panel. When the hinge is rotated, the aromatic substances are released in conjunction with the operation of opening the folding type portable telephone from the closed state. Furthermore, a sounding body is operated at a frequency of strongly generating an air vibration at a time defined in advance by timer control, so that fragrance of the aromatic substances is released outward by the air vibration of the sounding body. The fragrance corresponding to TPO can be generated from the face panel of the portable telephone.

Disclosed is an electronic device which is formed thin while maintaining good display by a liquid crystal display unit. Specifically disclosed is an electronic device wherein a main substrate (130) mounted with an electronic component is so arranged as to face a reflecting sheet (126) which is formed on the back surface of a liquid crystal display unit (110). A flexible substrate (140) arranged between the liquid crystal display unit (110) and the main substrate (130) is connected to a surface (132) of the main substrate (130), which surface (132) is on the side of the reflecting sheet (126). A protective sheet (150) covering the reflecting sheet (126) is interposed between the flexible substrate (140) and the reflecting sheet (126).
摘要:
A medical system control device comprises a first control unit for controlling at least a power supply to a plurality of devices configuring a medical system, a second control unit, the startup process time of which is longer than the first control unit, for controlling the entire medical system, and a storage unit for storing information at the time of an operation termination process for the medical system, which is performed by the second control unit. The first control unit controls a power supply to a predetermined device among the plurality of devices before the startup process of the second control unit is complete, according to the information stored in the storage unit in response to the power-on of the medical system.
