摘要:
A power-generation detection circuit for detecting a power-generation state by an AC voltage supplied from a power-generation device including a capacitor, and switching element, a resistor, and an inverter circuit which controls the charging of the capacitor by a power-generation device. The switching element is switched by the AC voltage from the power-generation device. The voltage of the capacitor is detected by the inverter circuit thereby performing power-generation detection.

A pulse motor driving device having a rotation detecting unit adapted to detect whether or not a pulse motor rotates. In this device, a control unit performs an operation of increasing the effective value of the driving power of the pulse motor and periodically performs an operation of lowering the effective value of the driving power thereof when it is detected by the rotation detecting unit that the pulse motor does not rotate. Further, the control unit interrupts the operation of lowering the effective value of the driving power of the pulse motor when a magnetic field is detected by a magnetic detecting unit.
摘要:
In an electronic apparatus which includes a power generator and a storage device for storing electric energy obtained thereby, it is detected whether a motor driven by the stored electric energy is rotating by comparing the rotation detecting voltage, which is proportional to the induction voltage generated in the motor caused by the rotation of the motor, with a rotation reference voltage. The generation state of the power generator or the charging state of the storage device is detected. The level of the rotation detecting voltage or the level of the rotation reference voltage is shifted by a predetermined amount based on the detected generation state of the power generator or the detected charging state of the storage device so that the voltage difference between the rotation detecting voltage and the rotation reference voltage is increased during the no-rotation period.
摘要:
In an electronic apparatus including a generator device for generating power, a storage device for storing the generated electric energy, and a motor driven by the electric energy stored in the storage device, it is detected whether a magnetic field is generated by power generation. If it is detected that a magnetic field is generated by power generation, a correcting driving-pulse signal having an effective power larger than a normal driving-pulse signal, which is output for controlling the driving of the motor, is output to the motor. In performing this operation, a determination is made by assuming that a magnetic field is generated while the storage device is in the charging state.

A junction block (40) includes a generally rectangular flat plate portion (42) attached to a side surface of an assembled battery. A control device (50) is disposed over a portion of the flat plate portion (42) which includes a middle of the flat plate portion (42) and which is positionally biased toward a lower side end of the flat plate portion (42). A connector-connecting portion (47) is provided in one of the four corners of the flat plate portion (42) that is a rear end corner of an upper side end opposite the lower side end of the flat plate portion (42). A rib (48) and a connector-connecting portion (49) are provided at a location on the flat plate portion (42) at which the rib (4) and the connector-connecting portion (49) clamp the electric power cable (28) that is connected to the connector-connecting portion (47) and that is laid along the upper side of the flat plate portion (42).
摘要:
The core layer of a core substrate is made of carbon fibers impregnated with resin. When the temperature of the core layer increases, the core layer suffers from an increase in the thickness because of thermal expansion of the resin. The core layer is sandwiched between the insulating layers containing glass fibers. The insulating layers serve to suppress an increase in the thickness of the core layer resulting from the thermal expansion of the core layer. Thermal stress is suppressed in the core substrate.

Large-sized through holes are formed in a core layer of a printed wiring board. Large-sized vias are formed in the shape of a cylinder along the inward wall surfaces of the large-sized through holes located within a specific area. A filling material fills the inner space of the large-sized via. A small-sized through hole penetrates through the corresponding filling material along the longitudinal axis of the small-sized through hole. A small-sized via is formed in the shape of a cylinder along the inward wall surface of the small-sized through hole. The filling material and the core layer are uniformly distributed within the specific area in the in-plane direction of the core substrate. This results in suppression of uneven distribution of thermal stress in the core layer in the in-plane direction of the core layer.
