摘要： A semiconductor device having a well region of a first conduction type formed in a main surface of a semiconductor substrate, and a nonvolatile memory element formed at the well region is provided. The nonvolatile memory element comprises a gate electrode formed over the well region through an insulating film for charge storage, and a source region and drain region of a second conduction type which are separated from each other and are disposed in the well region. The well region includes a third semiconductor region, a second semiconductor region which is arranged at a position deeper than the third semiconductor region, and a first semiconductor region that is arranged at a position deeper than the second semiconductor region. The first and third semiconductor regions, respectively, have an impurity concentration higher than the second semiconductor region.

摘要： A threaded fastener lighter in weight and easier to produce is made by the moderate temperature-forging, from a raw magnesium material that contains microcrystals whose diameter is about 100 &mgr;m or less. The raw material may be pure magnesium of industrial grade in one case, and alternatively be any magnesium alloy or such a composition as comprising as its matrix the alloy or pure magnesium, in the other cases. The raw material has a superplastic property and a fine-granulated metallographic internal texture, and when making the fastener, will be heated to 250-400° C. at which superplasticity takes place to facilitate the forging to form the fastener. A method proposed in the invention to make the fastener is thus such that the number of necessary processing steps is reduced and manufacture cost is lowered.

摘要： It is a technical common knowledge that a chaplet used in casting of a hollow casting is fusion-bonded with the melt and is incorporated into the casting. However, the adhesion between the chaplet and the casting body is not necessarily satisfactory, thereby incurring the strength reduction of a thin-wall hollow casting. A core for a thin-wall hollow casting according to the present invention is provided with a chaplet mounted thereon. The chaplet has arcuate portion 2 with a gap 5 and a plurality of projections 4 from an outer peripheral of the arcuate portion and is in contact with an inner wall 7 of a mold. The entire arcuate portion of the chaplet is included in a groove 6 formed around an outer peripheral portion of the core body. Only the projections 4 of the chaplet protrude from the core body, when the chaplet is inserted in the groove.

摘要： A main rocker arm which is pivotally mounted on a rocker shaft has one or more sub-rocker arms pivotally mounted thereon. The main rocker arm is arranged to synchronously open and close two poppet valves. Each of the sub-rocker arms can be selectively locked to the main one by way of hydraulically operated plunger arrangements. The main rocker arm is provided with a roller type cam follower which follows a low speed cam. The sub-rocker arms are provided with followers which engage high or very high speed cams. Lost motion springs which maintain the sub-rocker arms in contact with the cams are mounted on the main rocker arm.
