摘要:
A connector coupling structure includes first and second connectors including housings. A raised portion is formed at a front end side of an inner surface of the second connector housing. When the first and second connectors are coupled, the raised portion contacts an outer surface of the first connector housing, forming a clearance between the outer surface of the first connector housing and an inner surface portion of the second connector housing. An inner case is slidably received in one of the connector housings. A projecting portion is formed on a side of the inner case and a notching piece having a pawl is formed on the one connector housing to be releasably engageable with the projecting portion. When the terminals and terminal-inserting holes of the two connectors are connected with one another, the inner case slides so that the engagement of the pawl and the projecting portion is released.

An impact drill for boring a workpiece includes a main frame, a motor housed in the main frame, a spindle movably supported by the main frame and rotatable by the motor and movable in its axial direction, a first ratchet positioned fixedly with respect to the spindle, a second ratchet positioned with respect to the first ratchet, a spring biasing the second ratchet toward the first ratchet. The spring has at least one of a spring constant and a biasing force which prevents the second ratchet and the spindle from abutting against the main frame at least one of when a force ranging from 15 to 25 kg is applied to the main frame for boring the workpiece and when the spindle is moved to a retracted position.

An impact drill minimizing transmission of vibration to a handle gripped by a user's hand. A spindle extends through a main frame and is movable in its axial direction and rotatable about its axis. A first ratchet is rotatable and axially movable together with the spindle. A second ratchet is axially movable but unortatable. The first ratchet has a first serrated surface and the second ratchet has a second serrated surface in confrontation with the first serrated surface. In an impact drilling mode, the first serrated surfaces is brought into abutment with the second serrated surface so that the spindle is reciprocally moved in the axial direction. A first spring is interposed between the main frame and the second ratchet to urge the second ratchet toward the first ratchet. A second spring is interposed between the main frame and the second ratchet to urge the second ratchet away from the first ratchet. In the impact drilling mode, the second ratchet is always out of contact from the main frame and is floatingly maintained within the main frame.

The present invention provides a magnetic recording medium having excellent durability, high abrasive resistance and smoothness capable of suppressing development of uneven wear on a tape contact surface of a magnetic head at minimum. The magnetic recording medium has a base film and a magnetic layer provided on the base film. The magnetic layer includes metal magnetic powder of particles having an average long axis length of not more than 0.13 .mu.m, alumina powder of particles which have an average diameter of not more than 0.13 .mu.m, an .alpha.-rate of not more than 30% and pH of not more than 7.0, and a binder resin.

An electrical connector (30) and a method of making includes a base housing (40) holding contacts (41) on close spacing and a face housing (50) fitted onto the base housing to protect the contacts. The base housing (40) includes an alignment post (46) integrally formed with the contacts as intercoupled by a carrier section to tie the contact position and alignment post position together dimensionally. The alignment post includes a slot (45) receiving a fastener (35) fitted therein with barbs (37) projecting outwardly to latch the post and thereby the base and face housings to a printed circuit board for surface mounting to the traces of the board.

A vibration drill unit capable of obtaining an intensive drilling force. The vibration drill unit includes a first ratchet, anon-rotatable second ratchet having a claw engageable with the claw of the first ratchet, and a main body frame for accommodating a motor, a spindle, the first ratchet and the second ratchet. The respective claws of the first ratchet and the second ratchet include the first inclined surfaces formed so as to be engaged in the rotation direction by rotations of the first ratchet and so as to be separated from each other, the second inclined surfaces 34a-2 and 35a-2 having greater inclination in the reversed direction than the first inclined surfaces, top parts that link the upper parts of both inclined surfaces to each other, and flat parts that link the bottom parts of both inclined surfaces to each other.

An impact drill minimizing transmission of vibration to a handle gripped by a user's hand. A spindle extends tends through a main frame and is movable in its axial direction rection and rotatablea about its axis. A first ratchet is rotatable and axially movable together with the spindle. A second ratchet is axially movable but unortatable. The first ratchet has a first serrated surface and the second ratchet has a second serrated surface in confrontation with the first serrated surface. In an impact drilling mode, the first serrated surfaces is brought into abutment with the second serrated surface so that the spindle is reciprocally moved in the axial direction. A spring is interposed between the main frame and the second ratchet to urge the second ratchet toward the first ratchet. In the impact drilling mode, the second ratchet is always out of contact from the main frame and is floatingly maintained within the main frame even if a force ranging from 15 to 25 kg is applied to the main frame toward a workpiece.
