Abstract: The information processing apparatus includes a computation processing circuit of which a state is capable of being switched at least between an active state in which power is consumed, and a no-power-usage state in which power is not consumed; an event detection module that detects a first event used to shift the state of the computation processing circuit from the no-power-usage state to the active state; a power isolation circuit that isolates power of the event detection module from power of the computation processing circuit in the no-power-usage state; and an isolation canceling circuit that cancels, in the active state, the isolation performed by the power isolation circuit.

Abstract: A hand-held tool, such as a disc grinder, is used to perform work at a high work site, a countermeasure is taken to prevent the hand-held tool from falling by using a suspension tool, such as a tether strap. If a coupling part that couples the suspension tool to the hand-held tool is damaged, this fact is notified to a user. Thereby, an original function of the suspension tool can be reliably performed. If a large impact is applied to a coupling member via a suspension tool, the coupling member is displaced to a second position, due to the deformation of a first position retaining member. A conductive portion disengages from contacts to cause a power circuit to be shut off, thereby prohibiting a main body part from being activated.

Abstract: A side handle can be toollessly positioned on a tool body, and is attachable to power tools of multiple models and is highly versatile. A side handle is attachable to a side surface of a tool body included in a power tool. The side handle includes a rotation locking member attachable to the tool body in a manner of being restricted from rotating, and an operable portion operable to lock and unlock a position of the side handle relative to the rotation locking member.

Abstract: A handle for use with a power tool includes a handle body, a beam and a weight. The handle body includes a mounting part and a grip part. The handle body is configured to be removably secured to a tool body of a power tool. The grip part is formed in an elongated hollow shape. The beam is supported by the handle body in a cantilever manner and extends within the grip part. The weight is supported by the beam.

Abstract: A power tool effectively isolates vibration with an auxiliary handle having no structure for isolating vibration. A power tool to which an auxiliary handle is attachable includes a housing, a nut held on a side surface of the housing to be screwed with the auxiliary handle, and an elastic member between the housing and the nut.

Abstract: A grinding tool allows effective reduction of vibration while maintaining the compact product size. A grinding tool includes a motor housing accommodating a motor, a pair of housing halves screwed together across the motor housing and each including a screw boss extending through the motor housing, and an elastic member between the motor housing and each of the screw bosses in an axial direction of the screw bosses.

Abstract: When a tip of a blade cascade is ground with a grindstone, a jig is inserted between blade cascades of a blisk and a jig is inserted between blade cascades. A blade locking section of the jig locks with a side section in the width direction of a corresponding rotor blade via a damping member made from rubber or the like. A disk locking section of the jig locks with a disk of the blade cascade which the blade locking section locks with.

Abstract: A transmission device includes a first optical modulator configured to modulate, based on a packet signal for each of packets, input light into an optical packet signal and to output an optical packet signal for each of the packets; a generation circuit configured to generate an adjustment signal that adjusts slopes of a rise and a fall of a waveform of the optical packet signal; and a second optical modulator configured to modulate the optical packet signal from the first optical modulator and adjust, based on the adjustment signal, the slopes of the rise and the fall of the waveform of the optical packet signal.

Abstract: A vehicular emergency reporting device includes a voltage step-down unit, an auxiliary power source, a voltage step-up unit, a control unit, an emergency report executing unit, and a switching unit. When a decreased voltage decreased by the voltage step-down unit is lower than an increased voltage increased by the voltage step-up unit, the emergency report executing unit performs an emergency report using the increased voltage as the operation voltage. When the decreased voltage is lower than the increased voltage, the switching unit switches a power supply mode between a first mode in which the increased voltage is supplied to the control unit and the emergency report executing unit and a second mode in which an auxiliary power source voltage is supplied to the control unit and the emergency report executing unit without being increased by the voltage step-up unit.
