Title: Method of assaying organic material and inorganic material in graphite slurry
Inventor: SAKAI HIROKO
IPC: H01J29/32
Filed: 1988-04-01
Abstract: PURPOSE:To improve the accuracy of the determination of inorganic and organic dispersing agents, by decomposing the organic dispersing agent with inorganic oxidizing agent, performing the separation and the determination of graphite and the dispersing agent, ionizing the organic dispersing agent, and determining the quantity of the inorganic dispersing agent. CONSTITUTION:Sulfuric acid (1+2) is added into a specified quantity of graphite slurry, and strong acid is obtained. Inorganic dispersing agent in the graphite slurry is ionized. Then organic dispersing agent is oxidized and decomposed with the solution of organic oxidizing agent such as the solution of potassium permanganate. The concentration of the organic dispersing agent in the graphite slurry is determined based on the consumed amount of the solution of the potassium permanganate of standard organic dispersing agent whose concentration is known. Since the graphite in the graphite slurry after the dispersion of the organic dispersing agent is aggregated, only the graphite particles can be picked up on filtering paper by washing with water. The ionized metal in the filtering paper is measured. Thus, the quantity of the organic dispersing agent is indirectly determined by using the measurement.

Abstract: PURPOSE:To increase the joint strength of a composite material by inserting two sheets of strips into between a pair of rolls which rotate oppositely at the peripheral speeds different from each other to form the composite material then inserting such composite material between a pair of rolls which are disposed on the down stream thereof and rotate oppositely from each other. CONSTITUTION:Two sheets of the strips 1, 2 having different quality and characteristics are inserted into between a pair of the rolls 5 and 7 which rotate oppositely from each other, by which the strips are press-welded. The composite material 7 is formed to the prescribed thickness ratio by controlling the peripheral speed ratio of a pair of the rolls 5, 7. The material 7 is provided with the high joint strength by such press-welding method but the large residual stress is generated therein, by which the joint strength is decreased.

Abstract: PURPOSE:To avoid electrical discontinuity in a wiring layer on a semiconductor substrate even if the wiring layer is formed on a steep gradient stepped part and avoid the degradation of the characteristics of an LDD structure transistor after a long term usage by a method wherein a tungsten layer is selectively deposited on a high melting point metal nitride film deposited on the wiring layer. CONSTITUTION:A gate electrode 2 is formed on a substrate 1 and an oxide film 3 is deposited on the gate electrode 2 and the substrate 1. A wiring layer 14 made of Ti is formed so as to cover the oxide film 3 and contact holes 12 and 13. Further, a high melting point metal nitride film 15 made of TiN is formed on the wiring layer 14 to form a double-layer structure wiring. A W layer 20 is deposited on the double- layer film only by a selective CVD technology. The W layer 20 is deposited on the top surface and side surface of the double-layer film and W also penetrates into a cracking 17 to provide electrical continuity to the Ti layer 14. With this process, the Ti layer 14 can have sufficient ohmic contacts with both an N<+>type region 19 and a P<+>type region 18. With this constitution, as the cracking 17 is filled by the deposition of the W layer 20, it is not necessary to apply tapering work to the stepped part of the oxide film 3 and the contact holes 12 and 13 so that the manufacture can be simplified.

Abstract: PURPOSE:To superimpose a sound signal on a video signal without widening a transmitting frequency band to multiplex and transmit by providing an encoder for AM modulating a color burst signal in the video signal by the sound signal to form a multiplex signal in a transmitting side. CONSTITUTION:In the transmitting side 1, the process circuit 8 of a CCTV color camera 4 scans an object to output a color synthesized video signal obtained by adding a synchronizing signal such as the color burst signal (3.58 MHz) or horizontal.vertical synchronizing signals (fh, fv). The encoder 9 transmits the multiplex signal obtained by AM modulating the color burst signal in the color synthesized video signal outputted from the process circuit 8 by the sound signal from an LPF 7 through a transmission cable 3 to a receiving side 2. At the time of applying this AM modulation, since the frequency band of the sound signal outputted from the LPF 7 is below fh/2(=7.5 KHz), the sound signal is sampled by the frequency fh above twice as high as the sound signal and is mounted on the color burst signal to have no reflected distortion.
