PURPOSE:To always keep the control optimum even if a variety of vehicle parameters vary and control the travel state of a vehicle in an optimum condition without being affected by the 0 point drift of a sensor which detects the properties of the travel of the vehicle and high frequency noise. CONSTITUTION:A yaw rate sensor 24 detects a yaw rate gamma, one of the properties of the travel of a vehic...

PURPOSE:To form two pieces of sealed bag-form packages on the right and left, between a lateral sealing part on the leading end side and lateral sealing part on the rear end side. CONSTITUTION:A long band-form packaging film 9 is formed into a cylindrical shape while transferring the film in the longitudinal direction, and confronted side edges 9a, 9b of the film 9 are heat-sealed in the longitudi...

PURPOSE:To hold a bendable card-form object to be packaged at a specified location by a method wherein a feeding path is laterally provided on the outside of a web toward the side end and tangential direction, and a feeding means which feeds the card-form object to be packaged is provided on the feeding path at a location wherein the web is overlapped. CONSTITUTION:A web A is wound on a cylindrica...

PURPOSE:To prevent the trouble that a feeding string bites into a wound string by a method wherein a rubber string is wound in such a manner that a winding shape of the rubber string may be expanded as the sepal comes closer, for a rubber string tying machine wherein flanges are arranged at both ends of a winding shaft on which the rubber string is wound. CONSTITUTION:For a wound string 2, a rubbe...

PURPOSE:To obtain an inexpensive heat exchanger which is composed in the state that a sheet material is applied by a specific tensioning force in a skeleton structure and in which the replacement of the material, the free selection of heat exchanging surface area, and maintenance and management are facilitated. CONSTITUTION:A heat exchanging sheet laminate has a pair of sheet materials for forming...

PURPOSE:To suppress drop in capacity at the early stage of a lead alloy grid containing practically no antimony by conducting two steps formation in a specified positive electrode formation current density in the start of the formation and in the following larger current density. CONSTITUTION:A lead acid battery using a lead alloy grid containing practically no antimony in a positive electrode is ...

An eyeglass holder having a cross-shaped clip (305) on which two shaped parts (341) are fastened for holding the eyeglasses fast and clamping the eyeglass holder (301) firmly on the breast pocket of an article of clothing (317). The shaped parts (341) can be pushed over the ends (312) of the beam (309) and adapted to the size of the eyeglasses to be held. On the vertical beam (307) there is fasten...

A surface-emitting laser system includes a laser that emits a vertically divergent beam generally parallel to the substrate on which it is formed, and a turning mirror in the path of the beam that extends up from the substrate to a level well above the laser height. The extended mirror area reflects a greater portion of the beam than prior planar designs, increasing the output efficiency and provi...

The peripheral ring of a sector mold for tires is formed of an assembly of plates 1 resting against each other and stacked in such a manner as to push each other back. The ring therefore has a continuous tendency to increase in diameter. This tendency is resisted, for instance, by a conical hoop which simultaneously pushes all the plates 1 radially in the molding direction.
