Abstract: A process for producing a carbonic acid diester, which comprises carrying out a reaction in a vapor phase of an alcohol, carbon monoxide and oxygen in the presence of a catalyst in a fluidized-bed reactor so that an oxidative carbonylation of the alcohol occurs, thereby obtaining a carbonic acid diester, wherein a heat of reaction is removed by the latent heat of vaporization of the alcohol as a raw material. In the process, for example, either at least part of the alcohol may be directly fed in liquid phase into the fluidized bed or cooling pipes are disposed in the fluidized bed and at least part of the alcohol is introduced in liquid phase into the cooling pipes as a heat transfer medium so that the liquid alcohol is vaporized and fed into the fluidized-bed reactor. Carbon monoxide may be introduced together with the liquid alcohol into the cooling pipes. A process of high energy efficiency realizing an effective utilization of a heat of reaction and an apparatus there for are provided in the production of a carbonic acid diester in a vapor phase with the use of a fluidized-bed reactor.

Abstract: An n-type region isolated by a p-type region is formed on a p-type substrate. Within the n-type region, in order to constitute an npn-transistor, an n.sup.+ region, a p-type region and an n.sup.+ region are formed. Within the n-type region, a p-type region is formed, and an insulating film and a metal layer are successively stacked on the p-type region to form an oxide film capacitor. The p-type region of the oxide film capacitor is in contact with the n.sup.+ region of the npn-transistor by means of a metal wiring. Within a p-type region of the oxide film capacitor, an n.sup.+ region is further formed. An additional npn-transistor may be formed by the n.sup.+ region, the p-type region and n-type region.

Abstract: In a steering system that includes: an intermediate shaft on a steering wheel side; a pinion shaft on a steered wheel side; and a cross joint by which the intermediate shaft and the pinion shaft are rotatably connected to each other on a plane intersecting with each of the shafts, and that steers steered wheels by transmitting steering torque of a steering wheel from the intermediate shaft to the pinion shaft, a weakened portion is formed in a joint spider of the cross joint. The weakened portion can be identified in advance as a portion that breaks first. This makes it possible to realize a failure mode in which a vehicle is able to run by itself for a certain period of time after a failure.
