Title: Manufacture of semiconductor device
Inventor: TOMIJIMA YASUSHI
IPC: H01L21/288
Filed: 1998-11-24
Abstract: PROBLEM TO BE SOLVED: To prevent wiring short-circuiting failure due to the remainder of stripping of a barrier layer by forming a barrier layer on the through hole of a first wiring layer and an interlayer film, by forming a second wiring layer due to plating on the barrier layer, and by eliminating a conductive layer being different from the second wiring layer by photoetching. SOLUTION: An insulating film 2 covers a semiconductor substrate 1, and a first wiring layer 3 is formed. An interlayer insulation 4 covers the wiring layer 3, and a through hole 5 is formed. A TiN barrier layer 7 with the same superior barrier property as Pt is deposited onto a Ti conductive layer 6. Then, a second photoresist film 9 is deposited, and a second wiring layer 11 due to Au plating is formed. Finally, the second photoresist film 9 is eliminated, and the TiN barrier layer 7 and the Ti conductive layer 6 are eliminated by photoetching for forming multilayer interconnection in a part other than a part where the second wiring layer 11 is formed, thus preventing wiring short- circuiting failure caused by the remainder of stripping of the barrier layer.

Title: Multi-medium communication terminal equipment
Inventor: FUJIOKA SUSUMU
IPC: H04L29/10
Filed: 1992-12-14
Abstract: PURPOSE:To provide the multi-medium communication terminal equipment by which a data communication protocol is simplified while avoiding duplicated error detection by both a multiplex processing section and a data link layer by omitting error check implemented by the data link layer of an OSI reference model and using the multiplex processing section only to check an error of a data signal in compliance with the recommendations H.221. CONSTITUTION:The recommendations H.221 recommends it that a high-order layer of an H.221 processing section 336 becomes a data link layer 35 of an OSI reference model. In this case, the H.221 processing section and the data link layer 35 detect an error of a data signal in duplicate. Then the H.221 processing section 36 is ranked to a low-order position of the transport layer 33 in this execution example and an error detected by the H.221 processing section 36 is corrected by the transport layer 33.

Title: Process for workup of mother liquor obtained from production of adipic acid
Inventor: GEERUHARUTO FURANKU
IPC: C07C51/42
Filed: 1991-12-17
Abstract: PURPOSE: To regenerate the catalyst used as well as a high-purity dicarboxylic acid with high yield by treating a mother liquor resulting from the production process of adipic acid by oxidation of cyclohexanol or cyclohexanone with nitric acid.  
     CONSTITUTION: When a mother liquor obtd. in the production process of adipic acid by oxidation of cyclohexanol or cyclohexanone with nitric acid is to be treated, nitric acid is removed by azeotropic distillation with water under reduced pressure. Then the obtd. dicaboxylic acid melt containing copper and a V catalyst obtd. is heated at 130 to 180°C to decompose nitrogen compds. and oxalic acid included in the material. Then the material is dissolved in water and brought into contact with a cation exchanging material to fix and remove copper and V, and further distilled to remove water to obtain a dicarboxylic acid melt. The melt is heated to 200 to 240°C and finally distilled to obtain a mixture of dicarboxylic acids. This method is industrially advantageous because dicarboxylic acids containing a little amt. of nitrogen can be obtd. and the catalyst can be regenerated.

Abstract: PURPOSE:To attain the high speed operation without increasing the drive capability of a buffer by providing a circuit having a prescribed capacitance between an auxiliary signal line and an output signal line. CONSTITUTION:Output lines d0-d3 are charged to a high level when a control signal CL is at a low level, auxiliary signal lines i0-i2 go to a high level, and the output lines d0-d3 are charged to a high level by capacitors C0-C11 between the auxiliary signal lines i0-i2 and the output lines d0-d3.

Filed: 1990-11-30
Abstract: PURPOSE:To eliminate variation of input data and a software and to enable continuous automatic operation by setting a given threshold based on a detecting signal for a cutting force right before detection of a first spike signal detected each time cutting is effected one time. CONSTITUTION:A CPU 11 sets a given threshold based on a detecting signal value for a cutting force right before detection of a first spike signal detected each time cutting is effected one time. A cutting force detector 2 FM-modulates a torque thrust signal, by means of which torque thrust is indicated, to feed it to an antenna 3 and an amplifier 4. An FM modulating signal is detected by separating a high frequency, e.g. noise, by means of a low-pass filter 10 to provide a torque thrust signal. The torque thrust signal is converted into a digital signal by an A/D converted 5 and a result is inputted to the CPU 11. The result value is compared with a given threshold set by means of the CPU 11. When a torque thrust signal value exceeds a given threshold, an alarm signal is outputted through an I/O 16 for an alarm to an alarm device 17, and the alarm device 17 reports the alarm through display or by means of a sound.

On the other hand, on the side of the impeller, the lower portion of the liquid 0 is sucked under centrifugal pumping actions from the upper end opening of a cylindrical cover 3 to the side of the impeller and forced radially toward the cover 3 and then discharged downwardly. The liquid 0 is accumulated in a central cylinder so as to be recovered by means of a hose 4. As a result, separation and recovery can be accomplished efficiently.
