摘要:
A load port, which can selectively place wafer carriers differing in size on a table and can map wafers differing in size stored in the wafer carriers, and an adaptor, which can indirectly attach a wafer carrier on the table, are provided. A load port (100) includes a movable table (110) movably provided on the table (101), a module (161) for determining a carrier, and a module (162) for mapping a wafer. A wafer carrier (200) storing wafers (200A) is indirectly seated on the movable table via an adaptor (10), or a wafer carrier (300) storing wafers (300A) is directly seated on the movable table. The module (161) detects which of the wafer carriers is seated on the movable table and outputs a detection signal in response to the wafer carriers. The module (162) conducts mapping for the wafers, receiving the detection signal sent from the module (161).

A plasma addressed display device includes a flat panel, a scanning circuit and a signal circuit. The flat panel is of a superimposed structure of a plasma cell having scanning electrodes in a row configuration and a display cell having scanning electrodes in a column configuration. The scanning circuit sequentially applies selection pulses to the scanning electrode to scan the display panel. The signal circuit writes the picture data in the signal electrode in synchronism with this scanning. On the plasma cells, there are formed reciprocally isolated discharge channels in a row configuration. To each discharge channel, charged with an electrically dischargeable gas, are allotted plural scanning electrodes. As characteristic of the present invention, the scanning circuit sequentially applies the selection pulses to the scanning electrode allotted to a sole discharge channel to produce electrical discharge to form at least two scanning lines to a sole discharge channel. This realizes a high open area ratio and high resolution of the plasma addressed display device.

With a stage kept in an as-heated state, a semiconductor wafer is placed over the stage. Then, with the elapse of a first time, a controller causes a pressure inside a vacuum chamber to rise to a second pressure higher than a first pressure (step S40). After the semiconductor wafer is placed over the stage, a pressure difference between a pressure inside the vacuum chamber and a pressure inside an adsorption port is set to a minimum value at which the semiconductor wafer is not allowed to slide over protrusions. Further, in step S40 as well, the pressure difference is kept at the minimum value at which the semiconductor wafer is not allowed to slide over the protrusions.

An engine comprising a main intake passage having a throttle valve therein. A bypass passage is branched off from the main intake passage located upstream of the throttle valve and is connected to the main intake passage located downstream of the throttle valve. A flow control valve, actuated by a step motor, is arranged in the bypass passage. The step motor is controlled by an electronic control unit having three memories. The data, indicating the step position of the step motor, is stored in the three memories at the same time. When at least two pieces of data among the data stored in the three memories are the same, it is determined that the two pieces of data are considered as true data indicating the actual step position of the step motor.

A production process of pigment according to this invention comprises the steps of: a first step of forming an inorganic compound coating layer on the entire surfaces of scaly substrates made of ceramic; a second step of forming metallic glossy dots on the surfaces of the inorganic compound coating layer in a scattered manner by an electroless plating, and the metallic glossy dots occupying from 0.05 to 95% of the surfaces of the inorganic compound coating layer with respect to the total surface area of the inorganic compound coating layer; and a third step of irradiating ultraviolet ray on particles formed by the second step. The impurities and the like, which adversely affect the color hue of the pigment, have been discolored or faded away by the ultraviolet ray irradiation in the third step. Accordingly, the pigment having good weather resistance can be produced readily and stably by the present invention.
