Abstract: A semiconductor device includes: a lead frame that is formed of metal; a wiring substrate that is opposed to the lead frame; an electronic component that is disposed between the lead frame and the wiring substrate; a connection member that connects lead frame and the wiring substrate; and encapsulating resin that is filled between the lead frame and the wiring substrate and covers the electronic component and the connection member. The lead frame includes: a first surface opposed to the wiring substrate and covered by the encapsulating resin; a second surface located on a back side of the first surface and exposed from the encapsulating resin; and a side surface neighboring first surface or the second surface, at least a portion of the side surface exposed from the encapsulating resin.

Abstract: A steering device includes a rack housing portion housing a rack shaft, a pinion gear provided on one end side of the rack housing portion, a first supporting portion provided on the rack housing portion to support the one end side of the rack housing portion, and a second supporting portion provided on the rack housing portion to support the other end side of the rack housing portion. The second supporting portion includes a first vehicle body mounting portion and a second vehicle body mounting portion provided to project outwardly of the rack housing portion, the first and second vehicle body mounting portions being mounted on a vehicle body. The first and second vehicle body mounting portions are arranged to be shifted in an axial direction of the rack housing portion so as not to overlap in the axial direction.

Abstract: A layer comprising a stain resistant agent is formed on a treated surface of a ceramic product used with water so that a stain resistant treatment is applied to the treated surface. The stain resistant agent includes a silicon-containing functional group combining with the hydroxyl group present on the treated surface by dehydration or dehydrogenation. Consequently, a high stain resistant effect can be achieved from the ceramic product.

Abstract: It is an object of the invention to achieve both of centering of an input shaft and an output shaft to determine relative positions of the same in a neutral state and the centering of a mechanism for applying a preset force.

Abstract: An object of the present invention is to provide a power steering apparatus in which its neutral rigidity can be raised by applying a preset force and which is superior in its assembly performance and productivity.To attain this object, first supporting portions are formed in a pair of spring members disposed across the input shaft, and second supporting portions are formed in the input shaft so as to oppose the first supporting portions. When the input shaft and the output shaft are rotated relative to each other so that the balls or rollers are about to slip out of the first and second supporting portions, the balls or rollers roll and move while deflecting the spring members.

Abstract: A power steering apparatus having enhanced neutral rigidity and improved operation stability at the time of straight traveling. The apparatus includes a pair of spring members which sandwich an input shaft and are disposed in an output shaft or a member rotating integrally with this output shaft. A preset force is exerted by a spring force of the spring members.

Abstract: A flat type fluorescent lamp device is constituted by two transparent glass plates assembled and sealed together thereby forming a glass plate assembly, a discharge channel formed in a serpentine form by a groove on at least one of the two transparent glass plates with the inner surface of the groove carrying a fluorescent film. A pair of electrodes are provided, electrode each at each end of the discharge channel, a light diffuser provided on the front surface of the glass plate assembly and a light reflector is provided at the back surface of the glass plate assembly. In one aspect of the invention, at least another electrode is provided between the two electrodes thereby dividing the discharge channel into a plurality of individual discharge channels, in which case it is possible to ensure that all of the individual channels have the same electric characteristics and can be caused to be lit in parallel by a single power source.
