摘要:
The present invention proposes a semiconductor device, its manufacturing method and to an electronic apparatus thereof equipped with the semiconductor device where it becomes possible to make a CMOS type solid-state imaging device, an imager area formed with a MOS transistor of an LDD structure without having a metal silicide layer of a refractory metal, an area of DRAM cells and the like into a single semiconductor chip. According to the present invention, a semiconductor device is constituted such that an insulating film having a plurality of layers is used, sidewalls at the gate electrodes are formed by etching back the insulating film of the plurality of layers or a single layer film in the region where metal silicide layers are formed and in the region where the metal silicide layers are not formed, sidewalls composed of an upper layer insulating film is formed on a lower layer insulating film whose surface is coated or the insulating film of the plurality of layers remain unchanged.

The machine element selection support system comprises a database apparatus and a selection support server, while the selection support server is connected to a network. A customer, who wishes to select a machine element, gains access to the selection support server using a customer terminal. The selection support server receives, from the customer terminal, information relevant to the specifications and operating conditions of machine elements to be selected, the purchase conditions of the machine elements, and machine element selection information including information relevant to the output mode of information relevant to selection candidates, extracts selection candidates in accordance with not only the specifications and operating conditions information but also information stored in the specification databases and, in accordance with an output mode received, outputs to the customer terminal information relevant to the selection candidates that can satisfy purchase conditions of the extracted selection candidates.

An object of the invention is to provide a spindle apparatus which facilitates assembling and removing operations at the time of maintenance and which is low cost. In the invention, the diameter becomes smaller in the order of an inner peripheral diameter of an outer cylinder (3), an inside diameter of a stator (4), and an outside diameter of a bearing sleeve (11); a sub-assembly (2) made up of a front housing (8), a rotating shaft (6), and the bearing sleeve (11) is withdrawable from the outer cylinder (3); and the diameter of a rotating part in an arbitrary section located rearwardly of the bearing sleeve (11) is made smaller than a minimum diameter of a non-rotating part between a rear end of the bearing sleeve (11) and the section.

A grease replenishing device replenishes a grease-lubricated rolling bearing with a grease. The grease replenishing device has a storage chamber portion and a pressing member. The storage chamber portion stores the grease. The pressing member pushes the grease out of the storage chamber into an interior of the rolling bearing.
摘要:
A grease-lubricated rolling bearing has an outer ring having an outer ring race in an inner peripheral surface thereof, an inner ring having an inner ring race on an outer peripheral surface thereof, rolling elements rollably provided between the outer ring race and the inner ring race, and a grease supply element for supplying an additional grease in the rolling bearing. The amount of the additional grease to be supplied at a time is predetermined to be from 0.1 to 4% of the volume of space in the bearing.

A semiconductor device manufacturing process and a bias ECRCVD apparatus for the process. The semiconductor device manufacturing process comprises the steps of forming trenches in the surface of a substrate, forming an insulating film by bias ECRCVD over the surface of the substrate, etching the insulating film by lateral leveling etching so as to expand the width of grooves formed in portions of the insulating film which are formed in regions other than those corresponding to the trenches, masking the portions of the insulating film which fill the trenches and removing the portions of the insulating film formed in the regions other than those corresponding to the trenches. An etching stop layer is formed over the surface of the substrate before forming the trenches and the insulating film, and the etching stop layer is removed by etching after removing the portions of the insulating film which are formed in the regions other than those corresponding to the trenches by etching with the portions of the insulating film which fill up the trenches masked. The surfaces of the portions of the insulating film which fill up the trenches are finished so as to be flush with the surface of the substrate. Desirably, the etching stop layer is annealed so as to make the grains of the surface of the etching stop layer smooth so as to enable the complete removal of the portions of the insulating film formed in the regions other than those corresponding to the trenches.
摘要:
The present invention is concerned with a controlled drug release composition comprising a poorly soluble drug, a water-soluble macromolecular compound and biodegradable macromolecular compound, which composition can be freely tailored to the required solubility and release pattern of the poorly soluble drug through adjustment of the ratio of said ingredients.
