摘要： A battery charger comprises a rectifier connected to a source of alternating voltage for generating a rectified sinusoidal halfwave voltage and a thyristor connected in a first circuit between the rectifier and a rechargeable battery for applying the sinusoidal halfwave voltage thereto. An RC triggering network is provided in a second circuit between the battery and the gate of the thyristor for triggering the same into conduction to apply the sinusoidal voltage to the battery when the instantaneous value of the voltage is higher than the voltage of the battery. A temperature responsive switch is provided for disconnecting the second circuit when the battery is heated to a temperature higher than a predetermined value. Further provided is a transistor responsive to the temperature responsive switch for establishing a short-circuit path to the gate of the thyristor.

摘要： A safety device for preventing overspeed of a rotary shaft driven by an electrical motor is arranged to cut a portion of an electrical circuit feeding the motor with electrical power, by making a cutter received in a rotary member jump up or protrude by a centrifugal force acting on the cutter, so that dangerous overspeed is prevented. The cutter is movably received in a radial bore made in the rotary member, and receives a tensile force from a coil spring which is fixedly supported by the rotary member at one end of the spring. An adjusting screw, which is a cylindrical member, is provided for biasing the cutter against the tensile force from the spring. A critical rotational speed, above which the cutter jumps to break the electrical circuit, can be freely adjusted by changing the position of the adjusting screw. The change in position of the adjusting screw results in both the change of an eccentric distance of the cutter and the change of the tensile force of the spring.

摘要： At least two vibration proof elements are interposed between a tool body and the handle thereof. Each of the elements has a first supporting member connected to the handle, and two rubber blocks interposed between the first and second supporting members so that the element functions as a shock absorber. The first supporting member is partially received in the second supporting member in such a manner that the first supporting member is reciprocally movable with respect to the second supporting member when a force is applied to the element in a longitudinal direction of the tool body. Each of the first and second supporting members has a U-shaped portion so that the inner surface of the second supporting member abuts the outer surface of the first supporting member thus preventing the handle from excessively rotating about an axis perpendicular to the longitudinal axis, and passing through the elements.

摘要： A percussion drill comprises an open-ended, hollow cylinder having an air exhaust hole on the side wall thereof, a piston mounted in the rear end portion of the cylinder, and a slide shaft mounted in the front end portion of the cylinder. A drill bit is releasably attached to the forward end of the slide shaft for working with a material. Between the piston and the slide shaft is mounted a striker which forms a forward variable volume air chamber and a rearward variable volume air chamber. The piston is driven by a motor-crankshaft arrangement to reciprocate axially in the cylinder to cause a positive high pressure to develop in the rearward chamber, which pressure provides an impact on the striker whose mechanical energy is transferred to the slide shaft. A return movement of the piston develops a negative pressure in the rearward chamber to pull back the striker to the impact position. The striker is formed with an air passage which is open at one end to the forward chamber and at the other end to the side wall thereof for communicating the forward chamber to the atmosphere through the air exhaust hole of the cylinder. This communication is established when the workpiece is pierced to allow a negative pressure to develop in the forward chamber.

摘要： In a paper feed control system employing a pulse motor steppingly rotatable in response to driving pulses, paper feeding is controlled by a prepunched format tape wherein line pulses generated every one line feeding of the paper are in synchronism with perforations detected from the format tape. Briefly, the format tape is moved by the pulse motor, and when a first perforation is detected therefrom a predetermined number of the driving pulses is applied to the pulse motor, whereby the format tape is moved to an approximate midpoint of the perforation. A first line pulse is generated in response to the predetermined number of the driving pulses so that the line pulse is generated in approximate midpoint of the first perforation. Accordingly, the succeeding line pulses are generated in the approximate midpoints of the succeeding perforations.

摘要： A power operated screwdriver including a support shaft firmly secured to a motor housing, a gear driven by a motor shaft and rotatably mounted on the support shaft, a main spindle slidably mounted on the supported shaft and holding a detachable drill bit, and an intermediate clutch disc slidably mounted on the support shaft between the gear and the main spindle. The gear and the intermediate clutch disc are selectively connected and separated by a first clutch, while the intermediate clutch disc and the main spindle are always connected together by a second clutch. A compression coil spring acts between the support shaft and the intermediate clutch disc and urges the intermediate clutch disc toward the main spindle to disengage the first clutch. With this construction, the a rotational driving force of the gear is transmitted to the main spindle via the intermediate clutch disc and first and second clutches only when the screwdriver is performing a screw-driving operation. During a no-load rotation of the gear, the main spindle is separated from the gear so that the driver bit can be fitted in a groove in the head of a screw stably and reliably.
