Title: Wiring method for semiconductor integrated circuit
Inventor: ODAGIRI TAKAHIDE
IPC: H01L21/60
Filed: 1992-08-04
Abstract: PURPOSE:To make the formation of a shunt resistor possible for reducing the resistance of an interconnection between elements without depriving the interconnection of the degree of freedom of a wiring layout with polysllicon or metal that is originally necessary for a semiconductor integrated circuit by forming interconnections between elements, within a semiconductor integrated circuit, with a bonding wire. CONSTITUTION:Interconnections between elements within a semiconductor integrated circuit are formed with a bonding wire 12. For example, in addition to ordinary processes for manufacturing a semiconductor device, contacts 7 to which a shunt resistor is to be connected are formed, and pads 8 for bonding are formed at the same time that interconnections on the uppermost layer are formed. Thereafter, a passivation film is formed, and a pad contact hole is opened. When a chip cut out from that semiconductor substrate is packaged, the pads 8 for a shunt resistor are bonded simultaneously with a package and the chip being bonded together by means of bonding techniques, thereby forming a shunt resistor 12.

Title: Forming method for rolling mill
Inventor: HOIZUMI TOSHIHIDE
IPC: B21H1/06
Filed: 1990-08-08
Abstract: PURPOSE:To obtain a high-quality product without generating a recessed surface, i.e., concaving, at the end face by previously forming a notched part in the outer peripheral corner part of an annular rough material. CONSTITUTION:The recessed part, i.e., concaving, in the conventional technology is not generated if the annular rough material Wal is formed by forming the notched part 13 on the annular rough material Wal to form a spacing 12 between the end face 11b of the recessed part 7 on the roll side and the corner part 10b of the annular rough material Wal. The reason thereof lies in that the part of the corner part 10b moves axially if the annular rough material is so deformed as to reduce the width in the diametral direction of the annular rough material in the process of forming and, therefore, the central part moves cooperatively therewith.

Abstract: PROBLEM TO BE SOLVED: To automatically release the entanglement of a material to be fed in tooth-shaped fixed plates to easily prevent clogging by arranging a pair of small-sized cutters having the same constitution as rotary cutters under the tooth-shaped fixed plates. SOLUTION: In the case a material to be fed 25 such as a polyethylene bag is fused to discs 5 and collars 6 and does not fall left as it is cut and is transferred to tooth-shaped fixed plates 12 and gets caught in them, it is detected by a sensor. Based on a signal of the sensor, both rotary cutters A, B are stopped, and simultaneously a pair of small-sized rotary cutters C, D are moved to near the lower end of a material to be fed hanging down 23. After that, the pair of the small-sized rotary cutters C, D are rotated so that they can draw in the material to be fed 25, allowing it to be cut. On the other hand, when the material to be fed 25 has been drawn in and its entanglement has been released, both the rotary cutters A, B are rotated again to start the original cutting again.

Title: Optical disk device
Inventor: KAWAKAMI IZUMI
IPC: G11B7/0037
Filed: 1994-09-01
Abstract: PURPOSE: To prevent written data from disappearing by preventing the generation of an error at the time of write-back processing in a write cache. CONSTITUTION: At the time of receiving a command from an optical disk control device 36, a CPU 30 checks an error in write-back processing exists or not. At the time of ending the reception of writing data, the CPU 30 checks whether a data buffer area 43a is valid as a writing cache or not. Then the CPU 30 compares writin frequency stored in an EEPROM 41 with hysteresis frequency stored in the EEPROM 41 correspondingly to a specified number allocated to a write command, and when the writing frequency does not reach the hysteresis frequency, normal write-back processing is executed. When the writing frequency has reached the hysteresis frequency as the result of comparison, the CPU 30 executes write-back processing by executing alternate processing.
