A disc-like grinding wheel 5 is formed with a circumferential groove 5a, the opposite walls of which define grinding surfaces 5b. A rotated carrier 3 brings a load pin 55 into rotary movement relative to the grinding wheel 5 rotated about an axis 5z, so as to pass the load pin 55 through space between the grinding surfaces 5b, whereby opposite end faces 55a of the load pin 55 are ground simultaneously. Thus, time taken by a grinding process may be reduced as compared with a conventional method wherein one end face is ground at a time.

An image processor for combining a computer-readable coded image into a print image of a document including a document data main body and at least one associated data piece, has a print image generator that generates a print image of a document including an image of at least a part of the associated data, a coded image generator that generates a coded image to be combined into the print image, and a controller that determines whether or not the generated coded image can be combined into the image portion of the associated data by comparing a size of the generated coded image with a size of an image portion of the associated data, and combines the generated coded image into the image portion of the associated data on the generated print image, if it is determined that combining is possible.
摘要:
Source/drain regions of an MOS transistor are formed at a surface of a p-type silicon substrate. A storage node electrically connected to the source/drain regions penetrates a bit line to reach the n-type source/drain region. The storage node and the bit line are insulated from each other by a sidewall insulating layer. Thus, a semiconductor memory device suitable for high integration is obtained in which short-circuit between the storage node and the bit line on a gate electrode layer can be prevented.

A twist beam suspension includes a twist beam which is disposed so that the longitudinal direction thereof runs along with the transverse direction of a vehicle, and a pair of trailing arms being connected to a body of the vehicle and each of which is disposed at a respectively different longitudinal end of the twist beam and is disposed such that the longitudinal direction thereof runs along the longitudinal direction of the vehicle. The twist beam suspension further includes a restricting apparatus which restricts inward displacement of the pair of trailing arms relative to the body of the vehicle in the transverse direction of the vehicle prior to restricting outward displacement of the pair of trailing arms relative to the body of the vehicle in the transverse direction of the vehicle.
摘要:
An ultra high molecular weight polymer emulsion is produced by emulsion polymerization of a vinyl monomer, wherein the oxygen concentration in the aqueous phase of the reaction system is maintained at a smaller percentage by weight than the percentage by weight of the dissolved oxygen concentration in a 0.5 wt % sodium bisulfite aqueous solution. An emulsifier and a redox polymerization initiator are used for the emulsion polymerization.
摘要:
An apparatus for forming a thin film on a substrate has a first reaction chamber in which a thin film is formed by gaseous discharge and a second reaction chamber in which reactive atoms are generated. The first and second reaction chambers commuicate with one another through an orifice in the first reaction chamber. The first reaction chamber houses a device for generating a film on a substrate, and the second reaction chamber houses a device for generating reactive atoms. The orifice is disposed in the vicinity of both a film-forming region in the first reaction chamber and a reactive atom-generating region in the second reaction chamber so that reactive atoms from the second reaction chamber will pass through the orifice and enter the film-forming region in the first reaction chamber, combine with particles in the film-forming region to form a chemical compound, and accumulate on the substrate. In preferred embodiments, the reaction chambers are formed by a single housing having a partition which has an orifice therein and which divides the housing into two reaction chambers.
摘要:
A bushing type vibration insulator, for example, used as a suspension bushing of an automotive vehicle. The vibration insulator consists of an outer cylindrical member connected to one member of the suspension. The outer cylindrical member is connected through an elastomeric member with an inner cylindrical member which is connected to another member of the suspension. The inner and outer cylindrical members share a common central longitudinal axis. Two fluid chambers are formed between the outer cylindrical member and the elastomeric member and filled with a fluid. The fluid chambers are communicable through a communication passage formed through an actuator fixedly secured directly to the outer cylindrical member. The actuator is constructed and arranged to block fluid flow through the communication passage under a predetermined condition, thereby raising the spring constant of the vibration insulator.

A vibration isolating apparatus is interposed between a vibration generating portion and a vibration receiving portion. The apparatus includes a main body which has a portion thereof constituted by a resilient member. The main body is provided with a liquid chamber which is capable of being expanded and contracted. The liquid chamber is divided by a partition member into small liquid chambers which are communicated with each other through an orifice. The orifice is able to absorb low-frequency vibrations but unable to absorb high-frequency vibrations. For this reason, a resilient membrane is provided between the small liquid chambers in such a manner as to suppress the rise in pressure inside the small liquid chambers so that high-frequency vibrations are also absorbed. It is possible to enhance the high-frequency vibration absorbing effect by providing, together with the resilient membrane, an opening means having a cross-sectional opening area which is larger than that of the orifice but smaller than the effective cross-sectional opening area of the resilient membrane.
摘要:
A vibration isolating apparatus employed for mounting, for example, the engine of an automobile includes a tube communicated with a hollow chamber which is expanded and contracted by vibrations generated in the engine. The tube is provided therein with a mass member which has a larger density than that of a fluid sealed inside the hollow chamber. The mass member is movable by means of the circulation of the fluid inside the tube. Accordingly, the mass member encourages the occurrence of resonance of the fluid inside the tube, whereby the vibrations are absorbed by means of the air-column resonance.
