A bonding system 1 includes a plurality of laser resonators 7 and a plurality of optical fibers f1 to f36 each having a laser beam inlet connected to one of the plurality of laser resonators. The optical fibers are bundled, and laser beam outlets of the optical fibers are disposed so as to optically face a heating region S of an electronic component 3, and the heating region is irradiated with spots of laser beams emitted from the laser beam outlets. The heating region S is divided into at least corner sub-regions S1 at the corners of the electronic component and an inner sub-region S2 inside the electronic component, and the laser power of the laser resonators whose laser beam outlets face the corner sub-regions is set higher than the laser power of the laser resonators whose laser beam outlets face the inner sub-region.For example, in the case where the electronic component has a rectangular shape, the four corner sub-regions S1, which tend to dissipate more heat, can be heated with higher laser power, so that the electronic component can be uniformly heated.

An electric power steering device includes: a worm shaft including a first end portion and a second end portion; a worm wheel; a joint; and an urging member. The first end portion includes: a first tubular portion; a diameter enlargement permission portion to allow enlargement of a diameter of the first tubular portion; and an external teeth portion. The joint includes: a second tubular portion; and an internal teeth portion capable of engaging the external teeth portion. The electric power steering device further includes a diameter enlargement member which is arranged in the first tubular portion and which enlarges a part of the first tubular portion in an axial direction thereof to press the internal teeth portion toward the external teeth portion.

A bonding head 6 is provided with a tool base 8 in a housing 6A and transmitting laser beam L is configured such that the laser beam L transmitted through this tool base 8 can heat an electronic component 3 and bond the same to a substrate 2. A surface of a heat radiating member 15 is provided in contact with a surface of the tool base 8 on which the laser beam L impinges. This heat radiating member 15 has light transmittance for transmitting the laser beam L and also has thermal conductivity larger than the thermal conductivity of the tool base 8. The tool base 8 is heated during bonding treatment, but heat transmitted to the tool base 8 rapidly escapes to the heat radiating member 15 having larger thermal conductivity.

A vibration isolation device includes two attachment members inter-connected by an elastic member. One of the attachment members comprises a metal tubular member connected to the elastic member, a metal bracket in which the metal tubular member is press-fitted, and a plastic bracket supporting the metal bracket and adapted to be attached to a support body or a vibratory source. The metal bracket has an engagement portion press-fitted with the metal tubular member, and a non-engagement portion offset from the engagement portion in a radial outward direction and held out of press-fitted engagement with the metal tubular member, the non-engagement portion being connected to the plastic bracket with a second elastic member disposed therebetween.

A security apparatus. A service is supplied to a user while maintaining the security of the service. A person discrimination section discriminates the user to be supplied the service. A user situation decision section decides whether the user is under a situation to use the service. An infringement situation decision section detects whether a non-user intrudes into a use area of the service in order to decide whether the security of the service is infringed. A service control section supplies the service to the user in case the person discrimination section discriminates the user, and controls a supply of the service if the use situation decision section decides the user is not under the situation to use the service or the infringement situation decision section decides that the security of the service is infringed.
摘要:
There is disposed a damper made of a synthetic resin having at least a column-shaped member (pillar-shaped member) of which one end and the other end come in contact with a support yoke and a yoke plug, respectively. This damper restrains a teeth beating noise generated by a rack and a pinion, from being propagated from the support yoke to the yoke plug, lowers its noise pressure level or changes its noise quality.
