摘要:
A method and an apparatus for fitting bead portions of the tire onto a wheel substantially uniformly and at the same time for filling inner pressure into the tire. A wheel cap-shaped jig in the form of a disc is arranged on the side surface of the wheel. The periphery of the wheel cap-shaped jig progressively reduces outwardly in the rotating axial direction of the wheel. The tire is then obliquely arranged on the wheel through the wheel cap-shaped jig, and the bead portions are radially outwardly expanded along their circumferences so as to assemble onto the rim. An outer cylindrical member having an inclined annular end surface and an inner cylindrical member telescopically arranged in the outer cylindrical member are brought into air-tight contact with the rim and a side surface of the tire, respectively. While inner pressure is filled into the tire through the clearance between the wheel and the bead portion of the tire, the outer cylindrical member is lowered relative to the inner cylindrical member to bring the bead portions into close contact with the rim.
摘要:
A method for assembling a tire on the rim of a wheel and filling inner pressure in the tire. The wheel is fixed on a wheel table in an airtight manner to the table. The tire is arranged on the wheel and a pawl is moved along the circumference of the wheel or the wheel on the table is rotated to arrange the bead portions of the tire around the rim of the wheel. An outer cylinder member is brought into abutment against one of the bead portions to urge it toward the other bead portion and pressurized air is filled into the tire through a clearance between the wheel and the one bead portion of the tire to bring the bead portions into close contact with the rim of the wheel. Thereafter, pressurized air is further filled in the tire through the inflation valve of the wheel to maintain the inner pressure higher than the normal inner pressure and then the inner pressure is lowered to the normal inner pressure.

摘要:
A method for assembling a tire on a wheel without causing any detrimental deformation of bead portions of the tire. The tire is obliquely arranged on a wheel cap-shaped jig provided on the upper side surface of the wheel located on a flat surface to arrange the lower part of the lower bead portion loosely around the wheel. The lower part of the tire is inwardly urged, while the other part of the lower bead portion is radially outwardly expanded to arrange it along its circumference around the wheel, progressively. Moreover, the part of the upper bead portion is radially outwardly expanded and is urged downward toward the support surface to arrange it loosely around the wheel. The part of the tire corresponding to the part of the upper bead portion is inwardly urged, while the remaining part of the upper bead portion is radially outwardly expanded and is urged downward toward the support surface along the circumference of the upper bead portion to arrange it around the wheel, progressively.

The magnitude of an amount of correction of unbalance at each axially opposite end face of the rim-fitted tire and the position on a circumference of each of the rim end faces are measured by means of an unbalance measuring machine for simultaneously measuring an amount of correction of static unbalance and an amount of correction of dynamic unbalance. The magnitude of the amount of correction of static unbalance, the position of an amount of correction of static unbalance on a rim periphery for minimizing a magnitude of an amount of correction of residual dynamic unbalance, the magnitude of the amount of correction of residual dynamic unbalance, and the position of the amount of correction of residual dynamic unbalance on the circumference of each of the rim end faces are calculated on the basis of the magnitude of the amount of correction of unbalance and the position of the amount of correction of unbalance on the circumference of each of the rim end faces measured. A balance weight of a magnitude corresponding to the magnitude of the amount of correction of static unbalance is fixed at the calculated position on the rim periphery, and a balance weight of a magnitude corresponding to the magnitude of the amount of correction of residual dynamic unbalance is fixed at the calculated position on the circumference of each of the rim end faces, thereby correcting weight unbalance of the rim-fitted tire.

An apparatus for filling pressurized air into a tire includes a table for supporting thereon a tire mounted on a rim, an inner cylinder member air-tightly engageable with a flange of the rim, and an outer cylinder member air-tightly engageable with a side rubber of the tire and forming an air-tight space in cooperation with the inner cylinder member. The end face of the outer cylinder member air-tightly engageable with the side rubber of the tire is inclined to the rotating axis of the tire. Therefore, the bead portion of the tire needs only to get over the part of the hump of the rim positioned oblique relative thereto along its circumference little by little during filling pressurized air into the tire. As a result, the bead portion of the tire is only subjected to a little deformation and comes into close contact with the rim, the bead portion of the tire substantially uniformly closely contacts the rim. Therefore, the tire filled with pressurized air in this manner is in a complete state fully exhibiting its performance.

A computer system for an easy system/information management. A client (100) and a server (200) are connected through a network (NW) so that a hard disk (240) or a server storage device is stored with a server holding type application program such as a menu program (243) to be operated on the web browser of the client (100). The server (200) has a web server program (242) and provides a file in response to the request of the client (100). After having started a second OS program (151), the client (100) starts a web browser program (153) in a full-screen display, and gains access to the file which is set for each client (100) or user and expressed in URL.

An air bag system of the invention is attached using an attaching piece portion and includes an air bag which is inflated for deployment when an inflating gas flows thereinto. The air bag is attached to an inner panel by attaching an attaching bracket having a pair of strengthening plates provided on front and back sides of the attaching piece portion with a bolt as a fastening means. A through hole in the attaching piece portion is set to such a size that a location constituting a circumferential edge is disposed at a position deflected from an area between a head portion of the bolt and the inner panel when a fastening stem portion of the bolt is fastened to the inner panel. The bolt is fastened to the inner panel in such a state that only the attaching bracket is interposed between the inner panel and the head portion.

A multilayer ceramic substrate with multilayered circuit patterns, the improvement in which internal conductors for wiring are formed by a Ag base conductive materials capable of being co-fired with multilayered green ceramic substrate sheets in an oxidizing atmosphere and external conductors electrically connected with the internal conductors are formed by a Cu base conductive material, the external Cu conductors being formed in such a manner so that a liquid phase of Cu-Ag is not formed at the interface of the Cu conductor and the Ag conductor. Further high reliable resistors of RuO.sub.2 or Bi.sub.2 Ru.sub.2 O.sub.7 type may be integrally formed onto and/or inside the substrate. In such an arrangement, problems or difficulties caused due to Ag migration, incomplete binder removal, solder leaching, etc., are eliminated and thereby there can be a multilayer substrate with a high reliability and a high pattern precision.
