Title: Substrate processing device
Inventor: HIRAI NOBUYUKI
IPC: H01L21/027
Filed: 1996-04-01
Abstract: PROBLEM TO BE SOLVED: To prevent processing liquid from dripping around a substrate carry in entrance or a substrate carry out exit by attaching to shutter a hood member that covers the number surface of the ceiling part of the substrate carry in entrance or the substrate carry out exit of a processing chamber from downward. SOLUTION: A substrate cleaning device 1 that cleans substrates sheet by sheet while supplying processing liquid for the cleaning of substrate such as chemicals or pure water to a substrate W. A hood member 12 that the lower surface of the ceiling part 8a of the substrate carry in entrance 8 from downward is attached to a shutter 11 that opens and loses the substrate carry in entrance 8a. On carrying in of the substrate, the substrate W goes under the ceiling part 8s of the substrate in entrance 8 where no dew is condensed nor the processing liquid is adhered and the dripping of the processing liquid to the substrate W around the substrate carry in entrance 8 is prevented.  The similar effect is obtained when the hood member 12 that covers the number surface of the ceiling part 9a of the substrate carry out exit 9 is attached to the shutter 11 that opens or closes the substrate carry out exit 9.

Filed: 1988-04-30
Abstract: PURPOSE:To eliminate the error of time set by each slave station by producing a new time setting frame in consideration of delay time caused by the slave station when a slave station device receives the time setting frame from a master station and sending said new time setting frame to the slave station device. CONSTITUTION:A master station device 54 transmits a time setting frame including time information 16, delay time information 17 and passing slave station number information via a transmission means. A slave station device 55 receives said frame and adds the product of the delay time and the number of passing slave stations included in the received frame to the time information also included in the frame. The value of this addition is used as the set time and 1 is added to the number of passing slave stations included in the time setting frame as a new time setting frame. This new frame is sent to the device 55. Thus it is possible to correct the delay time of the device 55 and to eliminate the error of the time set by each device 55.

Title: Protecting method for electrode for plating
Inventor: HIRAKATA KAORU
IPC: C25D7/06
Filed: 1989-04-27
Abstract: PURPOSE:To avoid metallic chromium from being deposited on an auxiliary cathode and to enable both miniaturization of the auxiliary cathode and stable operation for a long period by specifying the material of the utilized auxiliary cathode in a back-up method wherein the service life of an insoluble electrode for plating chromium is prevented from being shortened. CONSTITUTION:An insoluble electrode is utilized as an anode and protective current is allowed to flow to the anode at a time for stopping electricity for plating while utilizing an auxiliary cathode provided in a plating tank. In the protecting method for the electrode for plating, as the auxiliary electrode, the electrode is utilized wherein a coating incorporating platinum group metal is formed on valve metal or valve metal-based alloy. Even when the current density of the cathode is made high, chromium is not deposited on the auxiliary cathode by such a method wherein this auxiliary cathode is utilized and protective current is always allowed to continuously flow to the anode. Therefore the auxiliary cathode can be miniaturized and operation is stably enabled for a long period.

Title: Pcm communication equipment
Inventor: SUGA SEIICHI
IPC: H04M7/00
Filed: 1986-05-09
Abstract: PURPOSE:To evade an erroneous state as if a unconnected channel is in use by making a code assigned to a time slot of the unconnected channel the same as a code appearing in the time slot at the channel connection and non- connection state. CONSTITUTION:When the channel unit 1 is in the non-talking state, a digital conversion circuit 6 outputs a non-talking code of '11010101' or '01010101'. Since a code conversion circuit 7 inverts the 0 code position of the non-talking code, the output code of the code conversion circuit 7 is '11111111' or '01111111'. On the other hand, since the input data line 100 of the multiplex unit 12 is connected to a power supply Vc via pull-up resistors 11a-11c to prevent the code level from being unstable, a code of level '1' is given always to the line 100 when no channel unit is connected. Thus, the code of '11111111' is applied from an idle channel and the code is equal to the code received from the channel unit of the non-talking state.
