Title: Method and device for preventing substrate electrification, and substrate cleaning device
Inventor: KOYANAGI TETSUO
IPC: H01L21/304
Filed: 1997-10-01
Abstract: PROBLEM TO BE SOLVED: To provide a technique for effectively preventing particles from sticking to a substrate surface by preventing electrification of the substrate, during such chemical process as HF process and water-washing process. SOLUTION: Chuck grooves 23a and 23b of a chucking arm 20, which are such parts and directly contacting a water W in a wafer-washing process and holding grooves 14a and 14b of a substrate-holding part 14 in a cleaning path 2a are of metal silicon which is a conductive material, and these parts are grounded at an outside of a cleaning device through a grounding line wired inside insulation. As a result of this, the static electricity occurring in the wafer- washing process is released to the ground through a set line, without the surface of the wafer W being electrified, so the particles are prevented from sticking to the wafer W, due to static electricity.

Title: Polarity discriminator for ami signal
Inventor: SAKANOBE KAZUNORI
IPC: H04L25/49
Filed: 1990-10-24
Abstract: PURPOSE:To discriminate whether or not the polarity of an AMI signal is correctly set by discriminating whether or not a polarity error is caused at a terminal equipment of a sender address based on the polarity of a start bit and the sender address of a received AMI signal in the reception of a reply signal. CONSTITUTION:The discriminator is provided with a start bit polarity detection means 3 detecting the polarity of a start bit of a received AMI(alternate mark inversion) signal and a transmission frame buffer 4 to store a frame of an AMI signal to be sent. Then a discrimination means 5 receiving the output of the start bit polarity detection means 3 and a sender address of a frame in the transmission frame buffer 4 at the reception of a reply signal after frame transmission discriminates whether or not polarity error takes place in a terminal equipment of the sender address. Whether or not the polarity of the AMI signal is correctly set is easily discriminated at the build-up of the transmission system or at the revision of the transmission system.

Title: Liquid crystal display device with auxiliary capacity
Inventor: MIMURA AKIO
IPC: G09F9/30
Filed: 1987-11-14
Abstract: PURPOSE:To provide a display device which is simple in stage and has high pattern disposition accuracy by using semiconductor layers which serve as a transparent electrode material constituting capacity electrodes and constitute thin film transistors as switching elements and forming these layers simultaneously. CONSTITUTION:An underlying film 2 is formed on a glass substrate 1 and polycrystalline silicon 3 on which thin film transistors are formed and capacity electrodes 6 consisting of polycrystalline silicon are formed thereon. Gates 4 are formed on the polycrystalline silicon 3, then n<+> sources and drains are formed. A protective film 5 consisting of SiO2 is thereafter formed over the entire surface. The protective film 5 serves as a capacity insulating film 7 in an auxiliary capacity part, on which picture element electrodes 8 are formed. The capacity electrodes and the islands of the semiconductor layers forming the switching elements are simultaneously formed in such a manner and, therefore, the stage for depositing the capacity electrodes is eliminated. The capacity electrodes are formable with good accuracy simply by separating the same semiconductor layers at the time of forming the switching elements.

Title: Method of removing slurry
Inventor: MATSUOKA SHINICHI
IPC: C07C51/43
Filed: 1994-11-21
Abstract: PURPOSE: To prevent pump operation from hindrance caused by allowing peeled- off matters to flow into a slurry removing pipe by a method wherein the slurry removing pipe is provided at the bottom of a stirring tank holding slurry in such a manner that its inner opening end projects upward from the tank bottom. CONSTITUTION: A slurry removing pipe 3 is provided at the bottom of a stirring tank 1 holding a slurry with the end part projecting toward its inside. The opening part 4 of a slurry removing pipe 3 is disposed above a position in which the peeled-off matters responsible for hindering the operation of a pump 5 are suspended. That is, since the peeled-off matters are considerably larger than the crystals forming the slurry, they cannot be suspended in the same way as the other crystals and are flowing mainly along the tank bottom. Therefore, if the slurry removing pipe 3 has its end opened in the bottom surface of the tank, the peeled-off matters are carried into the slurry removing pipe 3 with the slurry flowing thereinto. Conversely, when the slurry removing pipe 3 projects from the bottom of the tank 1 toward its inside, the peeled-off matters will not enter the slurry removing pipe 3, so long as they do not float to the opening part 4 thereof.

Abstract: PURPOSE:To obtain a contour line data converter of a character capable of generating a bold character or a void character keeping a printing quality by providing a contour line data changing means and a closed-loop synthetic means, and processing contour line data according to a prescribed rule. CONSTITUTION:The contour line data changing means, by processing the contour line data received from the outside according to the prescribed rule, moves at least one side of opposing contour segments each other among the contour lines fixing a character constructing area to the other, and is made to be a closed-loop contour line again. On the other hand, the closed-loop synthetic means removes the contour line segment rushing into the character constructing area of the other side concerning the contour line including the contour line segment moved through the changed contour line data and the contour line crossed to this, and defines it as one closed-loop contour line not to be crossed, and leaving the contour line not to be crossed as it is, the contour line data of the character composed of the one or plural closed-loop contour lines obtained from the result are supplied in a data converting means. Thus, it is possible to generate the beautiful character not including a white part not to be printed.

Title: Thin film magnetic head
Inventor: ANDOREASU YAANKE
IPC: G11B5/127
Filed: 1985-12-19

Title: Exhaust pipe
Inventor: KIYONO MASAYUKI
IPC: F02B27/00
Filed: 1995-09-28
Abstract: PROBLEM TO BE SOLVED: To prevent the lowering of power during low speed rotation of an engine by dividing an exhaust pipe into two pipes so as not to change cross-sectional area, and making the length of two exhaust pipes unequal. SOLUTION: Positive pressure wave generated by exhaust gas is divided to two exhaust pipes at a branch part 1 and becomes negative pressure reflected wave at each exhaust pipe end and returns to the branch part 1. The negative pressure wave of the short pipe 3 returns to the branch part 1 first, but since cross-sectional area is sharply changed at the branch part 1, this negative pressure wave proceeds toward an exhaust valve while generating positive pressure reflected wave. The positive pressure reflected wave becomes negative pressure reflected wave at the exhaust pipe end 4 and returns to the branch part 1.  During low speed rotation, the negative pressure wave from the exhaust pipe end 4 proceeding toward the exhaust valve while generating reflected wave at the branch part rebounds as it is at the exhaust valve and becomes positive pressure reflected wave at two exhaust pipe ends 4, and this positive pressure reflected wave and the negative pressure wave of the long pipe 2 returned to the exhaust pipe end 4 with delay negate each other. As a result, only the reflected wave becoming negative pressure reflected wave out of the positive reflected wave at the branch part 1 returns to the exhaust valve from the branch part 1.
