Title: Developing device
Inventor: KUROKAWA TOSHIO
IPC: G03D5/04
Filed: 1998-12-28
Abstract: PROBLEM TO BE SOLVED: To obtain a developing device which does not cause damage or wear to a photosensitive material and obtains a desired agitating capacity when the photosensitive material is processed by injecting a processing solution. SOLUTION: The developing device is constituted to execute the developing process by injecting a developer from plural blow-off ports 34 in a blow-off chamber 22 on the emulsion surface of a horizontally transported sheet of paper P. A blow-off surface is provided with recovery ports 46, which recover the developer blown off from the blow-off port 34 and impinged upon the sheet of paper P. Thus, a return water flow is generated, thereby allowing the developer to be uniformly agitated.

Title: Wafer chuck having cleaning function, and cleaning method therefor
Inventor: SHIGARAKI TOSHIYUKI
IPC: H01L21/683
Filed: 1998-12-28
Abstract: PROBLEM TO BE SOLVED: To cause dust to float and the floated dust to fall to outside of the chuck by sticking a piezoelectric element to the rear of a chuck or to a chuck- holding mechanism, and vibrating the chuck itself subjecting to ultrasonic vibration. SOLUTION: Electrodes 2 are so attached as to catch piezoelectric elements 3 and 5. Applying an AC voltage, where the phase is slid by 90 deg. from those of piezoelectric elements 3 and 5 with specified frequency, to the electrode 2 will generate ultrasonic vibration. When progressive wave is produced on a chuck 1, the dust adhering to the surface peels off and floats, and is carried outside the chuck 1. Monitoring the peeling condition of the dust and stopping only the application voltage to the piezoelectric element 5 according to the case will generate stationary waves 7 of ultrasonic vibration. The dust hard to peel off is caused to float by this partial vibration. As a result, this wafer chucks can fully secure a space above the stage, and this can be utilized effectively as a maintenance area or air conditioning space.  Moreover, this can prevent the enlargement of the device, and can lessen the installation area or the device weight.
