Abstract: A magnetic sensor whose electronic components will never become fatally damaged as the result of an external force. In this magnetic sensor, electronic components located near a connector are connected to a base and disposed in such a manner that the longitudinal axis of those electronic components are substantially perpendicular to the longitudinal axis of the base. A crack generating region is formed between the connector electronic component disposed near the connector. The crack generating region yields application of an external force on the base.

The surface mount electrode part is formed by at least the exposed part of the insert conductor and is connected to the magnetoelectric conversion device. The electronic component is mounted on the surface mount electrode part, and the connector part is formed by using an end of the insert conductor as a terminal electrode.

Abstract: A nailing machine includes a body, a driver extending downwardly from said body and vertically reciprocally movable for driving nails, and a driver guide for guiding the driver. A contact arm is movable between a lower first position and an upper second position and has a lower end for abutment on a work. The driver guide and the contact arm are fixed to each other and cooperate with each other to form a nail driving channel through which the nails are driven into the work.

A contact arm is movable between a lower first position and an upper second position and has a lower end for abutment on a work. A magazine is mounted on the body for feeding the nails into the driver guide. A trigger is operable by an operator for driving the driver. A trigger control device is interlocked between the trigger and the contact arm for permitting the driver to be driven by the operation of the trigger only when the contact arm is positioned in the upper second position. An idle driving prevention device is operable independently of the trigger control device for preventing the driver from being driven through operation of the trigger when the amount of the nails has been reduced to a predetermined amount.

Abstract: A magazine for use with a fastener driving tool is adapted for feeding a fastener stick having fasteners connected in series into a driver guide. The magazine has a magazine body and a slide door. The magazine body has a bottom defining a guide surface for the fastener stick. The slide door is mounted on the magazine body and is slidable in a feeding direction of the fastener stick relative to the magazine body between a closed position and an open position. The slide door in the closed position and the bottom of said magazine body cooperate to define a fastener storing chamber for storing the fastener stick therebetween. The fastener storing chamber is opened to the outside when the slide door is at the open position. A pusher serves to push the fastener stick in the fastener storing chamber in the fastener feeding direction.

The apparatus comprises a control means for detecting speedily reference positions for control of the individual cylinders with high reliability. In the control means, a reference position signal generating means for generating a reference position signal containing six equiinterval rectangular pulses each having a duty cycle of 1/2 during a single rotation of a crank shaft is provided in combination with a cylinder identification signal generating means for generating a plurality of different-interval rectangular pulses during a rotation of a shaft interlocked to the cam shaft so that a series of four successive signal levels of the different-interval rectangular pulses sampled at one edges of the equi-interval rectangular pulses differ from one to another succeeding series. The series of the signal levels thus fetched are stored in a signal level data storage means.

Abstract: An internal combustion engine control apparatus for performing the timing control such as ignition and fuel injection timing control with high accuracy even in a transient operation state such as acceleration or deceleration. A ratio between a first interval period extending from a first reference position to a second reference position and a second interval period extending from a second reference position to the first reference position is determined. A correcting coefficient is calculated on the basis of the ratio. By using this correcting coefficient, the predicted reference position period is calculated, on the basis of which the timing control is performed.
