    摘要: A power driven circular saw includes a base able to slidingly contact a workpiece and a saw unit positioned above the base and supported by the base. The saw unit includes a motor case accommodating an electric motor, a handle extending from the motor case and able to be grasped by an operator, a circular saw blade rotatably driven by the electric motor and positioned to partly extend downward below the lower surface of the base, and a blade case for substantially covering the upper half of the saw blade. A power indication lamp is disposed on one side of the handle and is illuminated when power is supplied to the circular saw.

    摘要: A trigger switch has a case member, a cover member, and an operation member configured to be used to carry out an operation. The case member and the cover member are combined with each other to form a waterproof case. When the operation member is operated, the operation member is displaced inward of the waterproof case. An internal pressure of the waterproof case changes in accordance with displacement of the operation member. The case member has a case base that is made from an inelastic body. The case base does not deform in accordance with a change in internal pressure of the waterproof case. The case base has at least one hole part. The case member has at least one deformation section that seals the at least one hole part. The deformation section is made from an elastic body.

    摘要: In a vehicular brake-by-wire braking system, during a four wheel simultaneous control mode when regeneration cooperative braking is implemented, a pair of electromagnetic isolation control valves and one of normally closed electromagnetic pressure relief valves corresponding to regeneration side left and right wheel brakes and normally closed electromagnetic pressure relief valves corresponding to non-regeneration side left and right wheel brakes are caused to operate to open and close, while the other of the normally closed electromagnetic pressure relief valves corresponding to the regeneration side left and right wheel brakes and the normally closed electromagnetic pressure relief valves corresponding to the non-regeneration side left and right wheel brakes are put in de-energized states in which the valves concerned are kept closed, and all normally open electromagnetic pressure supply valves are put in de-energized states in which the valves concerned are kept opened.

    摘要: An electric power tool is configured to control power supply to a motor based on an operational amount of the variable speed switch, and further configured to perform in an intermittent control mode in which power supply to the motor is varied intermittently in the same manner as if an ON operation and an OFF operation of the variable speed switch were repeated. It is also able to perform in a continuous control mode in which power supply to the motor is varied based on the operational amount of the variable speed switch.

    摘要: A motor controller comprises a processor selectively outputting an on-signal to either one of an upper arm switching element and a lower arm switching element based upon a detected position by the position sensor, gate drivers inputting a driving voltage to the gates of the switching elements by shifting a level of the on-signal from the processor to the upper arm switching element and a bootstrap capacitor configured to be charged while the upper arm switching element is turned off and to behave as a voltage supply for the gate driver while the upper arm switching element is turned on. The processor is configured to reduce a set duty ratio when the set duty ratio is equal to or larger than a predetermined value (e.g. 80 percents) and a rotational position of the motor does not change for a first predetermined time. This motor controller can prevent the switching element from a burnout even if the motor is locked.
