Abstract:
PROBLEM TO BE SOLVED: To provide a head of an electric soldering iron which is convenient for use.SOLUTION: The head of an electric soldering iron includes a heat conduction pipe connected to a heat conduction rod of the electric soldering iron, a connection unit fixed to the heat conduction pipe, a first heating block fixed to the connection unit, a second heating block slidably attached to the connection unit, and an operation unit rotatably attached to the connection unit. The operation unit includes a gear, the first heating block includes a first clamping part, the second heating block includes a second clamping part and a plurality of racks to mesh with the gear. When the gear is rotated, the gear meshes with the racks to allow the second heating block to slide relative to the first heating block to thereby adjust the distance between the first clamping part and the second clamping part.
Abstract:
A miniature housing, in whose housing body there is located an element emitting or receiving electromagnetic radiation, comprises at least two electrical terminal means projecting laterally beyond the housing body. The passage side of the miniature housing, through which the element emits or receives, is oriented substantially perpendicularly to the mounting plane of the miniature housing. The electrical terminal means of the miniature housing projecting laterally beyond the housing body are connected electrically conductively to conductors, which bring about direct contacting with the emitting or receiving element. The contacting faces of the terminal means are thus arranged substantially perpendicular to the passage side of the miniature housing. As a result of this arrangement the miniature housing may be embedded at least in part in a support, such that the miniature housing is no longer of any significance to the thickness of a lighting device.

PROBLEM TO BE SOLVED: To provide a production method for electronic circuit device which can prevent the non-mounting surface of a circuit board from swelling, when a casing is molded, and to provide an electronic circuit device which is formed by this production method. SOLUTION: As shown in Fig. (a), a circuit component 3, having a protrusion 33 formed on the surface becoming the side of a circuit board 2, is mounted on the circuit board 2 held in the cavity of a die and the tip of the protrusion 33 is substantially brought into point contact with the circuit board 2. As shown in Fig. (b), a gap formed in between the circuit board 2 and the circuit component 3 by the protrusion 33 is filled with resin that serves as a casing 4 and the air can be removed from the gap.

Abstract:
An electronic component including: an element (2) having a pair of terminal electrodes (11, 12); and a pair of metal terminals (21, 22) formed of metal materials respectively and connected to the pair of terminal electrodes (11, 12) respectively, characterized in that: a portion of the metal terminal (21, 22) that extends from a base-end side of the metal terminal (21, 22) connectable to an external circuit to face the terminal electrode (11, 12) of the element (2) is an electrode facing portion (21A, 22A); and a tip side portion of the metal terminal (21, 22) in the electrode facing portion (21A, 22A) is connected to the terminal electrode (11, 12), and a gap (S) exists between a base-end side portion of the metal terminal (21, 22) in the electrode facing portion (21A, 22A) and the terminal electrode (11, 12).
Abstract:
PROBLEM TO BE SOLVED: To provide an LED with an improved soldering structure, a method for assembling the LED to a substrate by soldering, and an LED assembly manufactured by the assembling method. SOLUTION: The LED comprises an LED chip, a pair of leads each having one end coupled electrically with the LED chip and the other end coupled with an external power supply and formed with a groove or a hole, a package body sealing a part of the lead on the LED chip side, and a transparent lens applied to one side of the package body on the LED chip side so that light emitted from the LED chip exits sidewards. By such an arrangement, work conditions are improved when soldering work is performed by mounting the other end of the lead on solder and strength after soldering can be enhanced while saving the solder material.
