Title: Production of hollow active carbon formed product
Inventor: FUJIMAGARI HITOSHI
IPC: C01B31/08
Filed: 1989-07-24
Abstract: PURPOSE:To utilize an active carbon present in the interior and improve an active carbon function by specifically treating the active carbon in calcining a principal material of an organic binder carbonizable by calcination and the active carbon and providing a granular active carbon formed product. CONSTITUTION:An organic binder carbonizable by calcination and active carbon are previously adhered to the surface of a granular substance vaporizable and consumable above a temperature at which the aforementioned organic binder starts decomposition and carbonization as a core substance and the resultant substance is calcined to afford a hollow active carbon formed product. In the process, active carbon having fine powder, present at the time of starting volume shrinkage in calcining, consumable after calcining by heating therein and applied to the outer surface thereof is used as the above-mentioned active carbon. The active carbon and the organic binder are prevented from directly contacting with the fine powder and further the carbide skeleton of the organic binder is left as columnar protrusions directing to the active carbon surface according to the aforementioned method. Furthermore, although the formed product assumes a hollow state by vaporization and consumption of the core substance, the hollow parts communicate with the outside.

Title: Semiconductor device and manufacture thereof
Inventor: TSUKAMOTO KATSUHIRO
IPC: H01L21/768
Filed: 1981-11-27
Abstract: PURPOSE:To obtain an excellent step coverage and easily open a through hole, by a method wherein on a thin silicon nitride film formed by plasma CVD, a thick phosphate glass is formed by vacuum CVD thereby to form an interlayer insulating film of double-layer structure. CONSTITUTION:A phosphate glass film 6 is etched with an HF etching solution by using as a mask a photoresist 7 formed by photoengraving for opening a through hole for making an electrode wiring contact between first and second layers. The etching is continued until a plasma silicon nitride 5 is exposed. Next, the plasma silicon nitride 5 is etched by a plasma etching employing CF4 gas to expose the surface of an AlSi wiring 31. Then, the photoresist 7 employed for opening the through hole is removed, and a second-layer electrode wiring 32 is formed. Thus, a multilayer wiring is obtained having a double-layered interlayer insulating film which is excellent in step coverage and easily etched for opening the through hole.

Title: Analog/digital conversion circuit
Inventor: IZUNO HITOSHI
IPC: H03M1/38
Filed: 1988-07-30
Abstract: PURPOSE:To eliminate the need for A/D conversion and to confirm the accuracy of a resistance ladder circuit in a short time by designating a test mode and reading a divided voltage designated by the resistance ladder circuit externally directly. CONSTITUTION:When a level 1 is set to a mode register 11, a selector 12 inputs an output of a counter 13 to a resistance ladder circuit 1. The resistance ladder circuit 1 outputs a prescribed division voltage alphaVr of a reference voltage depending on the content of the counter 13. When the resolution of the resistance ladder circuit 1 is 1/256, since the counter 13 handles 8-bit, the resistance ladder circuit 1 outputs a voltage corresponding to the count (m) of the counter 13, that is, a voltage being a multiple of m/256 of the reference voltage Vr. The voltage is outputted one after another by counting up the counter 13 and outputted to a terminal 2 via a switch 14. Thus, the test of the ladder resistance deciding the conversion accuracy is conducted by measuring the voltage alphaVr at the terminal 2 externally.

Title: Method and apparatus for stabilizing displacing characteristics of piezoelectric element
Inventor: OGAWA WATARU
IPC: H01L41/09
Filed: 1986-08-14
Abstract: PURPOSE:To be able to early stabilize a variation in a piezoelectric element by overlapping an AC attenuated voltage on a DC voltage and supplying it to the element when displacing the element or when altering its displacement. CONSTITUTION:When a DC application voltage Vd is varied to alter the displacement of a piezoelectric element 1, a detector 3 detects its variation to trigger an AC attenuation voltage source 4. As a result, the AC attenuation voltage VA is output toward an adder 5, and the voltage Vd is overlapped on the voltage VA by the adder 5. When the voltage from the adder 5 is applied to the element 1, its displacement during a transient period is varied in a large amplitude in response to the applied voltage which includes the component of the voltage VA, the variation in the amplitude is attenuated in a short time, and it is shifted to a highly stable range when the applied voltage becomes the component of the voltage Vd.

Abstract: PROBLEM TO BE SOLVED: To improve the free abrasive grain holding force of a composite polishing cloth and, at the same time, to enable the polishing cloth to efficiently make precise polishing by constituting the polishing cloth so that soft parts and hard parts can be scattered in the polishing cloth. SOLUTION: A hard urethane cloth 2 is stuck to a circular substrate 1 composed of felt, etc., and numerous scattered circular projecting hard parts 2a are formed on the surface of the urethane cloth 2 with a large circular projecting hard part 2b at the center. Then a soft part 3 is formed by sticking a nonwoven fabric to the upper surface of the urethane cloth 2 except the hard parts 2a so that their upper surfaces can be flushe with or can become slightly lower than the upper surfaces of the hard parts 2a. At the central part of the soft part 3, through holes 4 are formed at regular intervals around the hard section 2b. Therefore, a composite polishing cloth which has a high free abrasive grain holding force and can efficiently perform precise polishing can be obtained, because the soft part 3 holds free abrasive grains and the hard parts 2a and 2b polish the surface of a wafer.
