Title: Plasma apparatus
Inventor: KUDO HITOSHI
IPC: H01L21/3065
Filed: 1987-05-26
Abstract: PURPOSE:To arbitrarily correct the directivity of an ion by a method wherein a magnet used to form the center of a magnetic field at the outside of a plasma chamber is arranged near a substrate apart from a magnetic field used to generate a plasma. CONSTITUTION:A magnet coil 20 used to change a magnetic field is installed in addition to a magnet coil 1 used to satisfy an ECR(electron cyclotron resonance) condition. The circumference of a plasma chamber 2 is divided into several parts; four magnets 20A-20D are formed separately from each other. That is to say, the center 3 of the plasma chamber 2 does not coincide with the center 24 of the individual coils 20A-20D. When any one magnet (coil) acts in this structure, a magnetic field is tilted inside the plasma chamber. Since the center of the plasma chamber deviates from the center of the coils in the magnetic field, the magnetic field is intense in a specific direction of the plasma chamber. In the case of use for deposition, an electric current flows periodically one after another to the magnet coils used to change the magnetic field. It is desirable to set the intensity of the magnet coils in such a way that an incidence angle of an ion is changed at about + or -20-+ or -45 deg. near a wafer.

IPC: H04L12/42
Filed: 1994-05-19
Abstract: PURPOSE:To eliminate the discrimination of master and slave between communication nodes and to evade collision in transmission to a maximum by providing a communication state judging means. CONSTITUTION:When the communication node 10a performs transmission to the communication nodes 10b-10f, the CPU 11 of the node 10a fetches a busy signal from a busy signal line 1 via a receiver-15R and a buffer 15B, and judges whether or not it is busy. When it is not busy, the CPU 11 informs the start of transmission by its own to the nodes 10b-10f by setting the busy signal on the line 1 as busy via a buffer 14B and a driver 14D, and transmits data of first one byte to a communication line 2 via a buffer 16B and a driver 16D. The data is received by the nodes 10b-10f and the node 10a. The CPU 11 of the node 10a compares received data of one byte with the data transmitted by its own, and transmits the next data of one byte when coincidence is obtained between them, and when the transmission of all data is completed, the busy signal on the line 1 is released.

Filed: 1986-06-04
Abstract: PURPOSE:To prevent deterioration of the resolution of a tablet by cancelling the induced signal of the tablet affected by noises to perform the second scan after catching the timing of the noise signal produced from a display part through a coordinate detecting part. CONSTITUTION:A display control circuit 1 supplies the signals to a segment driver 3 and a common driver 4 for display on a liquid crystal panel 2 and also supplies the frame signal to a coordinate detecting circuit 5. The X and Y scan circuits 7 and 8 scan successively the sense lines on a tablet and obtain the coordinate detecting signal by the electromagnetic conduction with an energizing coil 9. The noise signal is synchronous with the rise of the frame signal and gives effects to the coordinate detecting signal. The circuit 5 incorporates an MPU and the frame signal is supplied to the interruption input terminal of the MPU. Then the MPU performs successively the scan and invalidates the scan of the timing by which an interruption is produced since this timing contains the impulsive noises. Then the same scan is carried out in the next timing.

Abstract: PURPOSE:To easily and continuously cast a tube with fins in inner face by surrounding a cylindrical mold with a cooling jacket, fitting a cylindrical sleeve having high heat conductivity and made of heat resistant material in inner face of this mold and arranging plural cooling water passage in thickness of the sleeve to the axial direction. CONSTITUTION:The cooled mold is dipped into molten metal 7 to depth, which the molten metal surface reaches to upper part of the sleeve 2, and the cooling water is caused to flow in the cooling water passage 1. As the cooling water passage 1 extends to the axial direction of sleeve, the parts of high and low cooling efficiency alternately exist to the peripheral direction in the inner periphery of sleeve. At the part of high cooling efficiency, solidifying velocity is fast and the solidified layer becomes thick. At the part of low cooling efficiency, the solidifying velocity is slow and the solidified layer becomes thin. The part, where the solidifying velocity is fast and the solidified layer is formed to thick, is formed to the inward fins 81 in the tube 8. By continuously drawing up the solidified layer, the tube 8 with inward fins can be easily and continuously cast. As the inner face in the sleeve 2 has smooth circular arc surface, increase of drawing-up resistance to the solidified layer of the molten metal is a little, and the developments of hanging up and crack are prevented.
