摘要:
To provide a method for industrially efficiently producing an exhaust gas purifying catalyst containing a perovskite-type composite oxide which is stable and has a less reduced specific surface area and is also effectively prevented from decreasing in its catalytic performance even in endurance in high temperature oxidative reducing atmospheres, a pre-crystallization composition containing elementary components constituting a perovskite-type composite oxide containing a noble metal is prepared, is mixed with a powder of theta-alumina and/or alpha-alumina to prepare a mixture, and the mixture is heat treated. Thus, the resulting perovskite-type composite oxide supported by the powder of theta-alumina and/or alpha-alumina can keep its thermostability at a sufficient level thereby to effectively prevent the catalytic performance from decreasing. This method can industrially efficiently produce the exhaust gas purifying catalyst.

A handling apparatus includes a main unit, a holder configured to hold an object, a retainer configured to retain the holder so as to allow the holder to displace with respect to the main unit, and a latch unit configured to selectively bring the holder into a latched state, in which the displacement of the holder with respect to the main unit is restrained, or an unlatched state, in which the displacement of the holder with respect to the main unit is not restrained.

A rebound-type hardness tester comprises a tubular member and an indenter hammer for undergoing axial movement therein in forward and rearward directions and for impacting a specimen and rebounding therefrom. A first detecting device detects the indenter hammer during movement thereof in the forward and rearward directions. A second detecting device detects the indenter hammer after detection thereof by the first detection device during movement of the indenter hammer in the forward direction, and detects the indenter hammer before detection thereof by the first detection device during movement of the indenter hammer in the rearward direction. A measuring device measures first and second timing values corresponding to different times elapsed from the detection of the indenter hammer by the first and second detection devices. A calculating device calculates an impacting velocity and a rebounding velocity of the indenter hammer in accordance with the first and second timing values and a distance between the first and second detecting devices. A processing device calculates a hardness of the specimen in accordance with the impacting velocity and the rebounding velocity calculated by the calculating device.

The invention has an object of automating the inspection of cell-gaps of a liquid crystal display panel. An RGB image formed on the surface of a liquid crystal display panel (15) to be inspected is picked up with a CCD camera (17), and color non-uniformity is analyzed by an image processing unit (18), thereby to inspect the non-uniformity of the cell-gap.

A memory circuit includes an input selector for receiving input data serially at an interval of a period T and outputting the input data and an address counter for generating first address data sequentially at an interval of a having period 2T and second address data sequentially at an interval having period 2T. The second address data is delayed a period T from the first address data. The memory circuit of the present invention further includes two memory blocks coupled to the input selector and address counter. One memory block stores even numbered input data in response to the first address data and outputs them at the interval of the period 2T. The other memory block stores odd numbered input data in response to the second address data and outputs them at the interval of the period 2T.
