Abstract: A steering device includes a steering column capable of a telescopic adjustment, a support bracket provided with an insertion hole, a movable tooth member fitted into the insertion hole with play in an axial direction, and a stationary tooth member arranged so as to face the movable tooth member. The movable tooth member has a first tooth, and is elastically displaceable to both sides in the axial direction from a predetermined neutral position. The stationary tooth member with a second tooth engageable with the first tooth is moved in a lateral direction to be brought into contact with the movable tooth member and to be separated therefrom. As a result, the second tooth is allowed to engage with the first tooth, and engagement between the first tooth and the second tooth is released.

Abstract: In a steering system, an energy absorbing member is plastically deformed by being drawn by a drawing shaft during a secondary collision. A first drawing shaft or a plurality of second drawing shafts is provided as the drawing shaft. The first drawing shaft or an adjusted shaft among the second drawing shafts is driven to change a drawing portion of the first drawing shaft that is engaged with the energy absorbing member to draw the energy absorbing member during the secondary collision or to change the number of the second drawing shafts engaged with the energy absorbing member to draw the energy absorbing member during the secondary collision such that a shock absorbing load is changed.

Abstract: In a steering column device, when a fastening bolt is rotated to a locked side, movement of a distance bracket in a telescopic direction is restrained by a movable die displaced by an urging force of an urging unit to bring a movable-side tooth portion into mesh with a fixed-side tooth portion and by a body mount bracket and the distance bracket brought into pressure contact with each other with an axial force of the fastening bolt. When the fastening bolt is rotated to a unlocked side, a restraint of movement of the distance bracket in the telescopic direction is released by the movable die displaced by a cam protrusion to bring the movable-side tooth portion out of mesh with the fixed-side tooth portion and by the body mount bracket and the distance bracket brought out of pressure contact with each other with the axial force of the fastening bolt released.

Abstract: A control unit of a wafer prober for implementing wafer examination, using a probe card including a multiple number of probes, executes a multiple number of measuring operations by bringing the probes of the probe card into contact with bonding pads formed on a wafer and by measuring the electric characteristics between predetermined pads of the bonding pads, each of the measuring operations being implemented after varying the relative position between the probe card and the wafer, in directions parallel to the face of the wafer. The control unit, upon execution of each of the measuring operations, implements the measuring operation after adjusting the relative position between the probe card and the wafer so that the contact position of each probe of the probes against each pad of the bonding pads is separated from all the positions at which the probes have already touched that pad of the bonding pads for a predetermined number of different times.

Abstract: Communication equipment that is provided with an isolating switch, which is operated by placement of a handset, instead of a conventionally used insulating component. The isolating switch constitutes an electrical insulation between a charging, terminal of a base unit and an external electric circuit. This structure eliminates the necessity of providing an insulating component such as a transformer and the like, so as to achieve a cost reduction of the communication equipment, and also improves sound quality of the communication equipment. In addition, the isolating switch is arranged in Such a manner that a direction of tile force applied by the handset to depress the terminal of the base unit and a direction of the force applied by the handset to depress a switch level are separated from each other. The isolating switch has a construction that enables the switch lever to function with a small loading weight, and to keep a contact point of the switch depressed by an intense force.

Abstract: A portable device includes: a front case comprising, about an edge of its border, a protruding front case fixing claw, and a recess formed on an inner side of this claw; a battery lid contoured to fit externally to a lower case at its outer border edge; a middle case contoured to fit into the front case and comprising, about an edge of its border, a protruding middle case fixing claw engaging in the recess; and the lower case coupled to the middle case and comprising a hole. Both the claws pass through the hole. The lid urges the front case claw toward the middle case claw while fitting externally to the lower case. With this configuration, the front case does not come off in use or on external impact, and the front case fixing element is not exposed to the outside of the device, thus providing excellent design.
