A dressing apparatus dresses a polishing surface of a polishing table used for polishing a workpiece such as a semiconductor wafer in a polishing apparatus. The dressing apparatus comprises a dresser body (31) connected to a dresser drive shaft (23) which is vertically movable, a dresser plate (32) which is vertically movable with respect to the dresser body (31), and a dressing member (22) held by the dresser plate (32) for dressing the polishing surface (1a).

A display apparatus comprises a display element, a backlight apparatus provided behind the display element and having a metal case, and a housing accommodating the display element and the backlight apparatus. In the display apparatus, electric wires for providing power to the backlight apparatus extend between the metal case of the backlight apparatus and the housing, and at least one opening is provided in the metal case in a part where the electric wires extend.

A vacuum apparatus has a process chamber for processing a workpiece and a transfer apparatus for positioning the workpiece in the process chamber and for removing the workpiece from the process chamber. The transfer apparatus has a pair of generally parallel and spaced-apart transfer bodies and a workpiece holder connected to the transfer bodies for supporting the workpiece. A feeding mechanism feeds the transfer bodies in a longitudinal direction thereof to position the workpiece holder and the...

Information or contents cannot be reproduced even from a regular storage medium which is encrypted in accordance with a predetermined encryption system, due to erroneous detection of watermarks. Detection of the watermarks and restriction over reproduction depending thereon is conducted only in a case where the medium is not encrypted. In case of detecting that the data is not encrypted in accordance with a predetermined encryption system by an encryption detection circuit (10) and when the wate...

A conveying apparatus for attracting and conveying a conveyed object by a belt provided with electrodes, includes an applying unit for applying a voltage to the electrodes to generate an electric force and a belt attracting unit for attracting the belt utilizing the electric force. Vibration of the conveying belt during conveyance can be suppressed and stable conveyance of a conveyed object can be realized.

In a coating apparatus for supplying a mixed solution of a resist solution and a thinner onto a wafer from a nozzle, the nozzle is connected to a mixed solution supply pipe, and the resist solution and the thinner are supplied to the mixed solution supply pipe from a resist solution supply pipe and a thinner supply pipe respectively through a junction pipe. The diameter of the junction pipe is set smaller than those of other supply pipes, whereby the resist solution and the thinner can be mixed ...

A transmitting apparatus and a reproducing apparatus include a converter for converting an input one-bit digital signal into a multi-bit signal while effecting down-sampling of a sampling frequency. A one-bit digital signal that could develop an overflow (clip) depending on its modulation degree is attenuated at a stage upstream of the input of the converter, and the multi-bit signal is amplified at a stage downstream of the converter to avert a clipped state between the stages.

A laminating apparatus includes a lamination object conveying unit for conveying an object, a laminating film conveying unit for conveying the laminating film, and a heating-pressurizing unit for overlapping the object with the laminating film, and heating and pressurizing the object and the laminating film. A heat dissipating unit is disposed downstream from the heating-pressurizing unit in a conveying direction, with the heat dissipating unit dissipating heat from the object and the laminating...

An elutriator for separating different grades of leaf material and having a distribution means, an elutriation zone (100) disposed above the distribution means, and a fluid supply fan (113) for supplying a fluid to me zone through the distribution means. The distribution means comprises two distribution plates (10) which diverge in an upward direction, each distribution plate being configured to direct the fluid therethrough in a direction which has a component extending along a surface of the p...

An apparatus for maintaining an electrophotographic apparatus with at least a photosensitive member comprises a first memory for storing a count value for the number of prints, and a second memory for storing the number of replacements of the first memory when the count value for the number of prints has reached a value based on which a decision is made whether the service life of the photosensitive member is expired. When it is determined that the value stored in the second memory has reached a...
