摘要:
Disclosed herein is a tapping screw (1) exerting an excellent anti-loosening effect with regard to a workpiece made of a soft material such as resin and an aluminum alloy. The tapping screw (1) includes a shaft part (3), and a normal thread (10) which is formed on the outer circumferential surface of the shaft part. A clearance groove (20) is formed by cutting out a portion of a ridge of the normal thread, and an engaging protrusion (30) is provided on a bottom of the clearance groove along a portion or an entirety of an edge of the bottom that continuously extends from a flank surface of the normal thread. The tapping screw (1) exerts an excellent anti-loosening effect even when a workpiece expands, contracts or oscillates because the engaging protrusions (30) are embedded into portions of the workpiece which have been embedded into the clearance grooves (20).

A waterproof bioelectrode includes an electrode pad (101) to be mounted on a living body and a lead wire (110) to be connected to the electrode pad. The electrode pad includes a waterproof base (106) having an adhesive contacting surface and a hole substantially at its center, a waterproof seal member (105) which fixes the lead wire to a lower surface of the contacting surface of the base while covering the hole such that a detection electrode provided to a distal end of the lead wire is exposed from the hole of the waterproof base, and a conductive gel (103) arranged on the contacting surface to come into contact with the detection electrode.

A parking lock device for an automatic transmission includes: a parking gear externally fixed to the output shaft; a parking lock pole displaced between a lock position, where the parking lock pole latches onto the parking gear to disable rotation of the parking gear, and an unlock position, where the parking lock disengages from the parking gear to enable rotation of the parking gear; a parking rod for displacing the parking lock pole toward and away from the parking gear; a drive lever that moves the parking rod; and a booster mechanism interposed between the parking rod and the drive lever that increases the driving force of the drive lever. Thus, the parking lock device makes the driving force applied by the drive lever when unlocking as small as possible and prevents inadvertent unlocking when in a locked state, thereby achieving smooth operation and enhanced reliability.

The present invention provides a device configured to present the feel of a plane or an object surface to a user using equipment configured to generate physical vibration such as a vibration motor or the like. A plurality of vibration motors including an eccentric rotor are put on a human body, and torque generated at the vibration motor along with an angular velocity fluctuation is provided to a skin surface in the horizontal direction with a different timing. Alternately generating torque by the plurality of vibration motors enables the user to perceive a plane or an object surface.

To provide an optical sensor unit in which the respective optical sensor elements can be easily provided on a curved surface without using wirings, a reduction in image pickup speed due to wiring delay is prevented to improve a photographing speed, and highly sensitive photographing is realized. The optical sensor unit is composed of an image pickup area section in which a large number of radio optical sensors are arranged and a radio communication means located in the vicinity thereof. The radio communication means has an image data signal circuit, a radio transmission circuit connected therewith, and an antenna. Each of the radio optical sensors is composed of an optical sensor element, a radio element, and an antenna.

A magnetization reversal method is a method of applying an external magnetic field to a magnetoresistive film, in which the magnetoresistive film has a structure wherein a nonmagnetic film is placed between magnetic films with an easy axis of magnetization along a perpendicular direction to a film plane and in which the external magnetic field is comprised of magnetic fields from a plurality of directions including a direction of easy magnetization of the magnetic films.
摘要:
A method is provided for removing plating blocking ions, such as anions, in pairs with copper ions and oxidant ions of a copper ion reducing agent from an electroless copper plating solution and keeping a constant salt concentration in the electroless copper plating solution during plating. The electroless copper plating method uses a plating solution containing copper sulfate as copper ion sources, and a copper ion complexing agent as copper ion sources, glyoxylic acid as a copper ion reducing agent, and a pH conditioner. The method is characterized by precipitating and removing sulfuric and oxalic ions in said electroless copper plating solution and keeping an optimum concentration of at least one of sulfuric and oxalic ions in said electroless copper plating solution during plating.
