The present invention provides an MWW type zeolite in which the ratio (B/A) of the peak intensity (B) attributable to tetracoordinate aluminum relative to the peak intensity (A) attributable to hexacoordinate aluminum is 2 or more inAl MAS NMR, when measured as an ammonium type. The present invention also provides a method for producing an MWW type zeolite, the method having a step for carrying out a hydrothermal synthesis reaction in the presence of: a seed crystal of an MWW type zeolite containing no organic structure-directing agent; and a reaction mixture containing a silica source, an alumina source, an alkali source, an organic structure-directing agent, and water. The reaction mixture satisfies the following molar ratio: X/SiO&#x3c;0.15 (here, X denotes the number of moles of the organic structure-directing agent).

Provided is a beta zeolite also having exceptional catalytic activity as a catalyst other than an olefin epoxidation catalyst. This beta zeolite is synthesized without using an organic structure-directing agent and has titanium in the structural skeleton thereof, the Ti content being 0.10 mmol/g or higher. This beta zeolite preferably has an Si/Ti molar ratio of 20-200. Also, the Si/Al molar ratio is preferably 100 or higher.

Beta zeolite, method for producing same, and catalyst

The purpose of the present invention is to provide a metal-substituted beta zeolite that exhibits a more excellent catalytic performance than conventional one, and a method for producing the same. The present invention provides a metal-substituted beta zeolite by subjecting an alkali metal-form beta zeolite produced without using an organic structure-directing agent to ion exchange with ammonium ion and then, using a filter cake procedure, to ion exchange with copper ion or iron(II) ion. The present invention also provides a metal-substituted beta zeolite which has been ion exchanged with copper ion or iron(II) ion and in which the amount of Lewis acid sites is greater than the amount of Bronsted acid sites when the amount of Bronsted acid sites and the amount of Lewis acid sites are measured by ammonia infrared-mass spectroscopy temperature-programmed desorption on the as-produced state.

This invention provides a traveling system for an engineering machine, adapted to limit a maximum traveling speed of the machine without causing decreases in engineering work efficiency or in accelerating performance during a start of traveling, and to improve fuel efficiency by suppressing a loss of engine output horsepower under the limited state of the maximum traveling speed. During fourth-gear shift control process, capacities of first and second hydraulic motorsare controlled in coordinative form and the second hydraulic motorhas its minimum tilting amount limited to a tilting amount limit q2cmin. In addition, when a tilting amount of the first hydraulic motorreaches a minimum tilting amount q1min, the enginehas its maximum engine speed limited to a first engine speed limit Ncmax1 (e.g., 1,800 rpm).

A forward/reverse control system for a work machine cancels a second control state, in which forward/reverse switching control is performed by a second forward/reverse control means, by an operation of a first forward/reverse control means to return to a first control state in which forward/reverse switching control is performed by the first forward/reverse control means. The system is provided with a F-N-R lever unit(the first forward/reverse control means) and F-N-R switch unit(the second forward/reverse control means) that instruct forward, reverse or neutral, a controllerwhich performs forward/reverse switching control by giving priority to an instruction from the F-N-R lever unitover an instruction from the F-N-R switch unitand a selector switchwhich by an operation of a switching control memberinstructs the controllerto switch to the second control state or to cancel the second control state. As a consequence, the system has made it possible to return to the first control state without an operation of the first forward/reverse control means.

When product inspection results and an inspection frequency for each inspection item are input to the product inspection result input device , the inspection items are selected, the presence or absence of product inspection results required for each inspection item is determined, selection of previous product inspection results is performed via the inspection item master and inspection frequency master of the product standard management device , and product inspection results for other product batches measured previously are cited for insufficient data for each inspection item missing from the inspection results document according to the inspection item conditions of the inspection results document. Next, an overall pass-fail determination is performed by comparing the product inspection results and input from the product inspection result input device for each inspection item and product inspection results cited for products of other batches, with product standards and tolerances stored in the inspection item master for each inspection item for products for each customer.
