Title: Method for manufacturing aluminum contact
Inventor: JASO MARK A
IPC: H01L21/321
Filed: 1997-12-10
Abstract: PROBLEM TO BE SOLVED: To eliminate an excessive amount of aluminum on the surface of silicon oxide by adhering an aluminum layer onto a metal-stopping layer so that a via and an opining can be filled and chemically and mechanically polishing the aluminum layer toward the metal-stopping layer downward and eliminating the metal-stopping layer. SOLUTION: An aluminum layer 26 is adhered onto a metal sopping layer 24 and an opening and vias 18 and 22 are filled. The aluminum layer 26 is not in a flay-surface shape on the opening but is lightly isometric. Then, the excessive amount of aluminum layer 26 treated by using CMP to eliminate an excessive amount of aluminum front the surface of a silicon dioxide layer. In this case, the metal-stopped layer 24 remains to exposed. Then, the exposed metal-stopping layer 24 is eliminated, for example, by normal etching. On the other hand, since aluminum is slightly indented due to a recess generated by CMP, silicon dioxide - aluminum layers 12 and 26 that are in flat-surface shape and are not damaged are generated due to etching or polishing.

Title: Control method for stepping motor
Inventor: KATO MASAYUKI
IPC: H02P8/22
Filed: 1993-12-15
Abstract: PURPOSE:To enable the improvement of pulse speed by reducing the number of divided micro steps to increase a step angle through which a motor is rotated in one pulse in a high speed range, and further shortening the pulse interval because of an additional time that is thereby given to CPU. CONSTITUTION:When the switching signal is off, the outputs QA, QB, QC and QD of a counter 2 are coupled with the address buses AO, Al, A2 and A3 in ROM 4, respectively. Each time the counter 2 has an input of one pulse, the addresses in the ROM 4 are updated by one, and data on the updated addresses is output to a digital-to-analog converter 5. At any point when the motor has been accelerated and the pulse interval approaches a time of speed control and linear interpolation control by CPU 1, the switching signal is turned on, and the address buses AO, A1, A2 and A3 of the ROM 4 are switched to '0' level, QA, QB and QC, respectively. At this time the pulse interval of output from the CPU 1 is doubled in synchronization with the turning on of the switching signal. This produces an additional time before the next pulse output, and makes it possible to shorten the pulse interval.

Filed: 1989-12-28
Abstract: PURPOSE:To enable determination of a time for replacement of various consumable items by recording, displaying and initializing a count value for each constant count in a count part which increments the count value only when a drive pulse is output. CONSTITUTION:A count value integrated so far is read from an EEPROM part 1 when a power supply is turned ON and then is set in a counter 2 as a count value. Next, a drive pulse sensor 6 detects whether a printing drive pulse is output, and increments a count value in the counter 2 for counting time only when the pulse is output. The value is sent to the EEPROM part 1 for every count and is stored there. In addition, the value is displayed in a display part 5 using a segment LED on a control panel. If a reset switch 7 is depressed, a counter resetting part 4 works and the count value of the counter 2 is initialized incrementing the value again starting with 0.
