Title: System and method for electro-chemical and mechanical polishing for magnetic board
Inventor: N NICHOLAS MANSER
IPC: B24B37/00
Filed: 1999-02-05
Abstract: PROBLEM TO BE SOLVED: To improve surface finished flatness after a polishing process, by polishing a medium in the presence of an electric field slurry by energizing a board, chemically and mechanically polishing a surface of the board, generating current between the board and a conductive member, and electrically polishing the board surface. SOLUTION: A rigid board 20 is polished by rotating and/or vibrating it in a state that it is pressed onto an abrasive pad 22 supported on a static abrasive platen 24. The board 20 vibrates and rotates at a place where slurry provided from a supply source 28 exists. This slurry is discharged on an interface between the abrasive pad 22 and the board 20 through one or more nozzle 30, and simultaneously a current supply voltage is impressed from a power supply 32 to a gap between the abrasive platen 24 and the board 20. The power supply 32 may be direct current(DC) voltage source, and at this case, preferably, the board 20 is a positive electrode (positive terminal) and the abrasive platen 24 is a negative electrode (negative terminal).

Title: Electron beam welding method
Inventor: MATSUDA SHIYOUZOU
IPC: B23K15/02
Filed: 1981-02-27
Abstract: PURPOSE:To prevent the generation of porosities and wormhole like beads in performing electron beam welding by changing the cross sectional shape of an electron beam from a circular shape to an elliptical shape at prescribed periods. CONSTITUTION:In electron beam welding, a deflection coil 2 for an electron beam 3 is provided in the lower part of a focusing coil 1 for the beam 3, and a transmitter 4 and an amplifier 5 are installed to the connection thereof so as to form Kapp's magnetic field when electricity is conducted to this coil 2. When the electrical circuit for forming the Kapp's magnetic field is held open, the cross sectional shape of the beam 3 is circular, and if the circuit s closed, the beam deforms to an elliptical shape. In this way, the cross sectional shape of the electron beam is changed periodically, by which the disturbance and pores in the flow of the molten metal in the molten pool in welding base metals are agitated and reheated, whereby the generation of porosites and wormhole beads is prevented.

Abstract: PURPOSE:To enable the control of recording with high precision and high resolution and to prevent color dislocation by installing a meams for controlling a recording sheet transfer speed in a transfer means while correcting the transfer speed corresponding to the correction degree in a correction degree calculating means. CONSTITUTION:A recording paper sheet 13 is drawn from a recording paper roll 1 and is hung between a recording paper feeding roller 5 and a press roller 6. In a print timing circuit 9, the clock pulses from a clock pulse generation circuit 8 are counted to make a printing panel for each value set. At the same time, a speed control signal circuit 11 generates a control signal indicating a preset standard speed and sends the signal to a speed control driving circuit 12. The recording paper sheet 13 is transferred at a standard speed, and a timing mark is written in a constant cycle onto the recording paper sheet. When a recording signal for the image signal of the color used for recording the timing mark is given simultaneously to a print head, the printing of the image is made possible.

Filed: 1998-02-12
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of overflow and underflow of an image buffer verification device as to a buffer for smoothing in the case of transmission of coded moving image data. SOLUTION: A discrete cosine transform DCT coefficient quantized by a quantization device 2 and processed by a scan order converter 3 is given to a variable length coder 4, where the coefficient is coded in variable length and the result is smoothed by a buffer 5 and then transmitted. A rate controller 8 determines an objective code amount to each picture and compares it with a code amount for each picture by the variable-length coder 4. When the code amount is deficient, code amount supplement devices 10, 11 use a specific code denoting a deficiency and stuffing process is conducted. Furthermore, the rate controller 8 determines an objective code amount for each macro block and a code amount adjustment device 9 reduces the excess codes with respect to the objective code amount by reducing the quantization DCT coefficient or supplements the deficiency by fixed-length coding.

Title: Multi-way multiplex communication system
Inventor: IWASAKI TOMOMI
IPC: H04B7/24
Filed: 1995-02-20
Abstract: PURPOSE: To shorten the period of polling to all terminal stations. CONSTITUTION: A BS timing signal generation circuit 11 generates a BS timing signal Ma to give differences to the timing, which is indicated by the BS synchronizing signal from a base station, among terminal stations. Battery saring of the terminal station is executed by the signal Ma. The base station multiplexes the peculiar number of the terminal station, of which maintenance information is requested, with a channel for maintenance to send this number. A maintenance information request signal detection circuit 17 recognized that maintenance information is requested if the peculiar number of the station itself coincides with the transmitted peculiar number. A maintenance information sending circuit 18a collects maintenance information and sends it from a transmission part to the base station.  Thus, successive polling to terminal stations become possible because the power-on time is different by terminal stations.
