Filed: 1984-06-13
Abstract: PURPOSE:To readily perform uniform etching, ashing and depositing by providing a pair of discharging electrode in a reaction tube, connecting a high frequency power source, and connecting a rectangular wave low frequency pulse generation source, thereby moving a plasma in a simple operation. CONSTITUTION:When a high frequency power source 4 is energized, a high frequency energy is input through a matching circuit 3 to discharging electrodes 2-A, 2-B of a reaction tube 1 of a plasma unit 5. On the other hand, a rectangular wave generated from a rectangular wave low frequency pulse generation source 6 is input through a filter circuit 7 to the circuit 3, and a plasma can be moved readily by varying the amplitude/period of the rectangular wave. Accordingly, uniform etching, ashing and depositing can be facilitated.

IPC: G03G21/00
Filed: 1993-05-24
Abstract: PURPOSE:To prevent a lot of developer from being discharged from a developer overflowing port when a developing tank is inclined, to suppress the deterioration of electrostatic chargeability and to excellently maintain image quality by allowing the developer flowing into a projecting part to overflow from a discharge opening formed on the projecting part, thereby discharging the developer from the developing tank. CONSTITUTION:When the developer is supplied to the developing tank 16, the developer of a quantity almost corresponding to an increase of the supply is discharged to a recovering container from the discharge opening 24e on the projecting part 24 of the developing tank 16, little by little. The discharge of the developer, at this time is executed in such a manner that the developer is spined out from the discharge opening 24e to the outside by the stirring blades 23b of a rotary discharge stirrer 23 or by the overflowing from the discharge opening 24e in a state where the discharge stirrer 23 is stopped. Since the developer is replenished and discharged in this way, the developer in the developing tank 16 is successively replaced with a fresh developer.

Title: Image encoding and decoding method
Inventor: OKA KENICHIRO
IPC: H04N19/00
Filed: 1994-06-03
Abstract: PURPOSE:To perform encoding for a desired composite image regardless of the way of the image layout, even if an image is composited in the state of a block truncation code of a fixed length. CONSTITUTION:As for partial images A and B, starting points (origins) for performing block divisions are matched. The layout information for partial image is held. Based on this layout information, an image is divided. When the end part of the partial image is included within a block like the block of an oblique line, a marker code ffff is set in place of a statistical parameter. When partial images are overlapped within the block like a block (b), a rewriting and encoding are performed for the quantization level of a picture element for which a substitute is to be performed. When the marker code ffff exists at the time of a decoding, layout information is referred and a decoding is performed by using the statistical parameters Sa and Sb within the complete blocks (a) and (b) which are adjacent within a pertinent partial image for every quantization level.

Title: Device for resist coating and control method therefor
Inventor: KIMURA YOSHIO
IPC: H01L21/027
Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To separate gas and liquid from effluent corrected from a device for spin coating without solidification. SOLUTION: Effluent and exhaust gas are together transferred to storing means 124a and 124b from a cup DC via common draining means 122a and 122b without separation of liquid and gas within the cup, and the effluent and the exhaust gas are separated in the storing means. These prevent the effluent from solidifying or being blocked within the cup DC. Also the storing means of this device always store predetermined volume of storing liquid, therefore mist can be absorbed from liquid surface of the drainage and solidification of the effluent within the storing means is prevented. Even when the device pauses, vaporized storing liquid is properly exhausted without the storing liquid being solidified within the storing means, because an exhausting dumper 136 capable of controlling opening can minimally exhaust.

Abstract: PURPOSE:To stabilize strip continuous casting by executing pouring while rotating pair of rolls at less than the aimed casting velocity at the time of starting the pouring and controlling rotating velocity of the roll after load of reduction reaches to the aimed load. CONSTITUTION:At the time of starting the continuous casting for the strip, the pouring into a molten basin 3 started while roatating the rolls 1a, 1b at 60-90% velocity of the aimed casting velocity V shown beforehand in the equation I.
