Abstract: PURPOSE:To aim at improvement in grinding efficiency, by making a cylindrical grinding wheel rotate in the center of an axial center in a direction to be crossed with a work axial center, and forming a curve corresponding to the outer circumference, in the case of turning curved surface for a work end face. CONSTITUTION:A work spindle 6 is driven into rotation by a motor 5b via a wrapping connector device 5a, and a work W being held by a collet chuck 7 is rotated as well. Simultaneously with this, a wheel spindle 12 is driven into rotation by a motor 11b and a wrapping connector device 11a, and a cylindrical grinding wheel G is rotated around an axial center ion the direction crossed with a axial center 2 of the work W whereby the outer circumference is formed into the form corresponding to a turning curved surface of an end face of the work W by a wheel former 18. And a wheel spindle stock 11 is moved by a pulse motor 17 via a feed screw 15, and an end face 1 of the work W is cut in with the periphery formed with the cylindrical grinding wheel G, thus it is ground into the desired turning curved surface. Doing like this, the cylindrical grinding wheel is no longer largely moved, and that since a large diametral grinding wheel is usable, so that grinding efficiency is sharply improvable.

Title: Semiconductor device and its manufacture
Inventor: YANO TAKASHI
IPC: H01L21/31
Filed: 1994-03-17
Abstract: PURPOSE:To prevent an oxide aluminum film from forming between an aluminum alloy film and a titanium nitride film as an anti-reflection film. CONSTITUTION:An aluminum nitride film 4 is formed between an aluminum film 3 and a titanium nitride film 5 as an anti-reflection film. The aluminum film 3 is composed of aluminum alloy containting silicon (about 1.0%) and copper about 0.1%). When the aluminum film 3 is protected with the aluminum nitride film 4, aluminum oxide is not formed on the surface of the aluminum film 3 at the time of contact with air. Thereby electrons, which have concentrated on the aluminum film 3, are dispersed in the aluminum film 3 and the titanium nitride film 5, or the aluminum nitride film 4, so that electromigration life is improved.

Title: Encoded data editing device
Inventor: UI SHUNJI
IPC: H04N19/00
Filed: 1995-03-07
Abstract: PURPOSE: To edit encoded data excellently without causing the input buffer of a decoder to overflow or underflow when the encoded data after editing are decoded. CONSTITUTION: An encoding part 2 generates 1st encoded data by compressing and encoding an input moving picture signal. Further, the encoding part 2 when replacing part of the 1st encoded data generates 2nd encoded data by re- encoding the input moving picture signal corresponding to the replacement place. At this time, a control part 3 makes the encoding part 2 perform the encoding by regarding a VBV(video buffering verifier) buffer occupation amount as an initial value and also controls the re-encoding by the encoding part 2 by adding dummy data, etc., for compensation so that the code amount of the 2nd encoded data matches the code amount of a substitution part 6 when the code amount of the 2nd encoded data does not exceeds the code amount of the substitution part 6 and is small.  Therefore, VBV control can be performed continuously, so the data can be edited excellently without causing the decoding- side input buffer to overflow or underflow.

Title: Semiconductor device
Inventor: MUTO SHUNICHI
IPC: H01L29/68
Filed: 1986-03-05
Abstract: PURPOSE:To obtain sufficient current gain in an HET, by using a strain super lattice, in which a semiconductor wherein scattering between valleys is hard to occur, is made to be one constituting semiconductor as a base, and forming another semiconductor constituting the strain super lattice so as to have a thin thickness in such a way that quantum mechanic reflection does not occur. CONSTITUTION:InAs is effective as a semiconductor used for the base layer of an HET. As the structure of the base layer, InAs/GaAs is used. GaAs is put at every 25Angstrom  so as to ease strain. In this method, misfit transfer does not occur even in misalignment of lattices of GaAs and InAs by 6.5%. When the thickness of the GaAs is made to be about three atomic layers, the quantum mechanic reflection of hot electrons in the base layer due to the use of heterojunction is sufficiently small. Thus, the heterojunction HET characterized by no effect of lattice misalignment and high current gain at room temperature is obtained.

Abstract: PURPOSE:To exactly grasp the leak quantity and to prevent the deterioration of the plant efficiency by deciding whether a signal is in an increase tendency or a decrease tendency by an effective value level of a specific frequency band of a spectrum of an input leak signal and calculating the leak quantity. CONSTITUTION:A leak signal detected by an acoustic sensor 2 is analyzed as to its frequency by a signal processor 4, and also, an effective value is calculated and inputted to an arithmetic unit 20. A leak deciding means 7 compares the effective value of the leak signal with a reference effective value set in advance and decides whether a leak exists or not. As a result, in the case a leak exists, by a leak sound tendency deciding means 21, whether a leak sound is in an ascending tendency or a descending tendency is decided in accordance with whether an effective value level of a high frequency band is large or small. Subsequently, by using a result of the means 21, a leak quantity search means 8 calculates the leak quantity. In such a way, the leak quantity can be grasped exactly against any valve and deterioration of the plant efficiency caused by a valve leak is prevented.

Title: Treatment of sludge
Inventor: TSUCHIDA SHIZUO
IPC: C02F11/00
Filed: 1997-02-18
Abstract: PROBLEM TO BE SOLVED: To surely deodorize a sludge containing an organic substance, recycle the deodorized sludge and avoid trouble in cement baking operations by cooling a waste gas from a cement baking kiln, introducing the cooled waste gas into a cyclone, mixing the collected dust with a dehydrated sludge, deodorizing the sludge and then using the resultant mixture as a raw material for a cement. SOLUTION: A waste gas from a cement baking kiln with a suspension preheater is bled at about <=5% and cooled to <=600 deg.C which is the melting point or below of a chlorine-alkali compound. The resultant waste gas is then introduced into a cyclone and the collected dust of coarse particles having about >=10μm size is then mixed with a dehydrated organic material-containing sludge at >=1/20 weight ratio. The dust contains a quick lime component, has a high activity, quickly causes hydrating reaction with water in the sludge and has great deodorizing effects. The resultant deodorized sludge, together with a raw material for the cement, is charged into a cyclone inlet in the topmost stage of the suspension preheater. When about <=10% pulverized coal is added to the collected dust, the deodorizing effects are improved.
