摘要:
A drive device (42), a traction sheave (41) and a weight-side stop portion (46) are arranged above one (21L) of a pair of left and right cage-side guide rails and a cage-side stop portion (44) and speed governor (47) are arranged above the other (21R) cage-side guide rail. Also a wide workspace can be guaranteed in the middle of the floor (31) of the machinery chamber (30), since the control panel (48) is arranged along the middle of the inside wall surface (37) of the front face of the machinery chamber (30). Furthermore, provision of an additional supporting beam mounted in the building is unnecessary, since the machine beam (53) can extend fully in the forwards/rearwards direction in the interior of the machinery chamber (30).

A submount can mount on it a semiconductor light-emitting device with high bonding strength, and a semiconductor unit incorporates the submount. The submount comprises (a) a submount substrate, (b) a solder layer formed at the top surface of the submount substrate, and (c) a solder intimate-contact layer that is formed between the submount substrate and the solder layer and that has a structure in which a transition element layer consisting mainly of at least one type of transition element and a precious metal layer consisting mainly of at least one type of precious metal are piled up. In the above structure, the transition element layer is formed at the submount-substrate side. The semiconductor unit is provided with a semiconductor light-emitting device mounted on the solder layer of the submount.

In this method, a ground wire 2 is overlaid on a shield wire 1 in cross. Next, overlapping portions of the shield wire 1 and the ground wire 2 are interposed between an upper resin tip 13 and a lower resin tip 14. By executing a first ultrasonic oscillation while inserting a projection 7a of an ultrasonic horn 7 into a through hole 13b of the tip 13, outside rinds 1d, 2b of the wires 1, 2 are removed in the vicinity of the overlapping portions. Next, by arranging a low-melting metal 15 and a resin piece 16 on a contact between the braided wire 1c and the core line 2a and executing a second ultrasonic oscillation, the contact can be brazed with the mutual welding of the tips 13, 14.

There is provided a spread illuminating apparatus to improve the coupling efficiency between members constituting a light source. The light source comprises a bar-like light conductive member and spot-like light sources. The spot-like light sources are mounted and soldered on an FPC, the light conductive member is fitted between the spot-like light sources, and ends of the light conductive member face light emitting surfaces of the spot-like light sources. The FPC has a deformed portion shaped U and forming an open area. An elastic force is generated in the longitudinal direction when the open area is expanded, by inserting the light conductive member whose length is larger than a distance between the spot-like light sources, between the spot-like light sources. This elastic force makes the light emitting surfaces of the spot-like source press on the ends of the light conductive member, and the coupling efficiency therebetween is improved.

At least two coated electric wires W1 and W2 are superposed. Resin chips 53 and 55 are disposed above and below the superposed connection portion S. These resin chips 53 and 55 have been compressed from above and below and ultrasonic vibration has been applied thereto, thereby melting resin coats 3 in the coated electric wires W1 and W2 to pressure weld conductive wires 1. The resin chips 53 and 55 and the resin coats 3 have been melted and joined to each other, and the resin chips 53 and 55 have also been joined to each other by melting. A pair of resin sealings 4 are provided between the upper resin chip 53 and the coated electric wires W1 and W2 and between the lower resin chip 55 and the coated electric wires W1 and W2. Each resin sealing 4 has rubber elasticity and is formed such as to annularly surround conductive wires 1, which are exposed from the resin coats 3 and pressure welded.
摘要:
A claw-pole stepping motor with rotor, including a vibration reducing magnet. Vibration in the axial direction is suppressed by having a correction force, which overcomes a force produced by a vertical motion caused when the rotor is pulse-driven, and keeps the rotor attracted to one side. The corrective force is generated between an index generating magnetized portion in a lower area of the rotor and a soft magnetic material base. Magnetic flux leakage produced by the excitation of the stator coils of the motor is suppressed by providing a shield ring made of a magnetic material on an inner side of the rotor magnet, which minimizes the magnetic flux flowing from the coils to the revolving shaft, and noises on the recording and reproducing head are thereby greatly reduced.

An half-fitting prevention connector includes a pair of female and male connectors to be fitted and connected to each other, an elastic member disposed in a housing of one of said female and male connectors, a repulsion force of said elastic member preventing said female and male connectors from half-fitting to each other, a lock member disposed in said housing so as to be slidable in a direction of mutual fitting of said female and male connectors for locking the other one of said female and male connector in said housing on the basis of function of said elastic member; and a support mechanism for supporting said lock member so that said lock member is slidable in said housing.
摘要:
A shield plate for preventing the leakage of a magnetic flux and for reducing acoustic/electromagnetic noise leaking out from the interior of the motor is arranged so as to cover the corresponding end surface of an armature. The inner diameter of the shield plate is made smaller than the outer diameter of a rotor in order to prevent the rotor from being detached from a stator assembly.
