摘要:
The invention relates to a three-dimensional model data generating apparatus which can generate efficiently and accurately three-dimensional model data of a structural member constituting a machine tool. A three-dimensional model data generating apparatus 1 has: X-, Y-, and Z-axis imaging mechanisms 21, 22, 23 each of which has two CCD cameras that are spaced apart from each other by a predetermined distance, and which image a structural member constituting a machine tool 10 in the respective directions of the X-, Y-, and Z-axes (three orthogonal axis directions), thereby generating two-dimensional image data; and a model data generating section 31 which generates three-dimensional model data including at least shape data which define a three-dimensional shape of the structural member on the basis of the generated two-dimensional image data.

In the presence information management method of the present invention, the e-mail address of the user and the terminal address of a terminal are extracted upon receipt of an e-mail transmission request, the e-mail address and terminal address correspondence table is retrieved by using the extracted e-mail address, and the extracted terminal address is registered in the e-mail address and terminal address correspondence table if the retrieved terminal address does not correspond to the extracted terminal address. Thus, the user can automatically update presence information with his/her e-mail transmission request.

A control apparatus for a roof glass specifies the selection position of the selection switch when an output voltage from the selection switch is determined to be included in any of the allowable ranges predetermined respectively for the selection positions of the selection switch. The selection position of the selection switch is settled when the specified selection position has not changed even when a predetermined time passes after specifying of the selection position of the selection switch. When those selection positions which have been settled at a time of making the current decision and at a time of making a previous decision satisfy predetermined conditions, the roof glass is allowed to operate to a position corresponding to the selection position of the selection switch settled at a time of making a current decision.

A charged particle beam test system identifies a fail signal generated at the predetermined timing for evaluating a semiconductor device under test (DUT). The charged particle beam test system includes a column for irradiating a beam pulse upon the DUT and detecting secondary electron emitted therefrom, an IC tester for supplying a test signal to the DUT and generating a trigger signal and comparing an output signal of the DUT with an expected signal and generating fail signals when output signal fails to match the expected signal, a sampling pulse generator for generating a sampling pulse for driving the column at a predetermined time after the trigger pulse, a fail signal separation circuit for identifying a fail signal generated at the specified timing, and a test result memory for storing measured data from the column representing an amount of secondary electron emitted from the DUT when the fail signal is received from the fail signal separation circuit.

A composite film consisting of particles of fibers dispersed in a metal matrix and formed by electroless deposition can be improved in appearance and particle or fiber content by adding a water-soluble amine or ammonium salt to the electroless plating bath. Preferably the bath contains a water-soluble nickel or cobalt salt, a hypophosphite reducing agent, a chelating agent for chelating the nickel or cobalt ion, a surface active agent, water-insoluble particles or fibers typically of polytetrafluoroethylene, and the water-soluble amine or ammonium salt.

A composite plating apparatus includes a plating tank for receiving therein a composite plating solution containing water-insoluble particles or fibers and a reservoir disposed adjacent the plating tank through an overflow weir, preferably in a common housing, the plating solution flowing into the reservoir in an overflow manner. A pump is disposed within the reservoir having a suction port for drawing the solution in the reservoir and a discharge port for pumping the solution. A conduit connected to the pump discharge port extends therefrom over the bottom of the plating tank through the overflow weir and includes a plurality of orifices. The plating solution is circulated by causing the solution to flow over the weir from the plating tank to the reservoir, pumping the solution to the conduit, and injecting the solution into the tank through the orifices to uniformly agitate the solution.
