Title: Production of dialkyl carbonate
Inventor: EERIHI BORUTAASU
IPC: C07C68/00
Filed: 1993-02-25
Abstract: PURPOSE: To almost quantitatively and selectively form a dialkylcarbonate by using a catalyst which is stable and excellent in wear resistance and which maintains high selectivity for a long time.  
     CONSTITUTION: This dialkylcarbonate is produced by the reaction of carbon monoxide and alkyl nitride in a continuous vapor phase reaction by using a platinum group metal catalyst deposited on an amorphous alumosilicate having 30 to 80 at.% of Al based on the sum of Al and Si. The catalyst may contain additives comprising antimony, bismuth, aluminum, copper, vanadium, niobium, tantalum, tin, iron, cobalt, nickel or a mixture of plural elements of them. During the reaction, halogenated hydrogen is intermittently or continuously added.

IPC: B41J35/14
Filed: 1980-05-07
Abstract: PURPOSE:To enable the use of an ink ribbon over its whole width without wastefulness and to lengthen the life of the ink ribbon, by making an inclined angle between the running direction of the ink ribbon and the dot-aligning direction of a head, and directing either the rightside or the leftside of the ink ribbon in turn to the head. CONSTITUTION:The ink ribbon 4 is positioned between an object to be printed and a printer head 2 having a plurality of wire dots 1 aligned in one line. The running direction of the ribbon 4 is arranged at an inclined angle with the dot-aligning direction of the head 2. According to this arrangement, only a single side 5 of the ribbon 4 along its width can be directed to the head 2, and the position directed to the head 2 can be alternatively switched to the opposite side 6 by the movement of the ribbon 4. For instance, the head 2 is arranged at the ribbon-exposing part 9 of an endless ribbon cassette 7 provided with the ribbon 4. In this case, the cassette 7 is swung either rightwards or leftwards by a rotary solenoid 10, so that the inclined angle between the running direction of the ribbon 4 and the dot-aligning direction of the head 2 can be switched to either rightward or leftward.

Title: Voice document preparing device
Inventor: YONEYAMA MASAHIDE
IPC: G10L15/00
Filed: 1983-04-06
Abstract: PURPOSE:To shorten time for inputting, facilitate ''kana-kanji'' (Japanese syllabary-Chinese character) conversion and improve processing speed by inputting part corresponding to kanji in inputted sentence continuously in two syllables and inputting parts corresponding to kana in monosyllable. CONSTITUTION:A voice recognizing section 3 converts inputted voice to corresponding kana letter information and stores in a memory 30. A ''kana-kanji'' converting section 4 converts stored kana letter information to writings mixed with ''kanji'' basing on ''kanji-kanji'' word dictionary 41. In this case, monosyllabic parts are written in kana, and parts of two continuous syllables are written in ''kanji''. Thus, as the parts corresponding to ''kanji'' are inputted in two continuous syllables, number of punctuation is reduced compared with the case where inputting is made by one syllable and time for inputting can be reduced. Further, as ''kanji'' parts and kana parts are inputted separately, ''kana-kanji'' conversion becomes easy, time for processing is shortened and processing speed can be increased.

Title: Damping device for vibration damping of structure
Inventor: MAEHATA KAZUHIDE
IPC: F16F9/20
Filed: 1995-03-20
Abstract: PURPOSE: To avoid mechanical collision by presuming piston stroke amount based on piston speed and by closing a control valve when the stroke amount reaches a predetermined limit value to inhibit further piston movement. CONSTITUTION: Right and left cylinder chambers 13a, 13b are communicated with each other through a communicating circuit 15. An internally filled working fluid moves between both the cylinder chambers in accordance with displacement evolved by a piston 11. The communicating circuit 1 5 is provided with an electromagnetic proportional control valve 30 to provide resistance to the flow of the working fluid according to its degree of opening, generating damping force. In attenuating relative displacement between a brace and a beam serving as earthquake-proof elements on evolving swinging to a structure, piston stroke reaches maximum stroke to collide the piston 11 with a cylinder wall. A risk of damaging a damper 5 exists. However, piston stroke amount is constantly presumed to close an electromagnetic control valve 30 when a predetermined limit value is observed.  Thus, the movement of the working fluid between the cylinder chambers is inhibited to inhibit the destruction of the damper 5.

Title: Sulfuric acid composition having low surface tension
Inventor: HARA HISAO
IPC: H01L21/304
Filed: 1989-03-15
Abstract: PURPOSE:To reduce the surface tension of a compsn. and to improve the wetting property to a body to be treated by adding a specified fluoroalkylsulfonamido compd. as a fluorine-contg. surfactant to the compsn. made of a mixed sulfuric acid-hydrogen peroxide soln. CONSTITUTION:When a mixed sulfuric acid-hydrogen peroxide soln. is used to clean an Si substrate, to remove a resist film or as part of the compsn. of an etching soln. in a semiconductor producing stage, the reactivity of the mixed soln. is not satisfactory because the soln. has high surface tension and inferior wetting property. A fluoroalkylsulfonamido compd. represented by the general formula (where R<1> is fluoroalkyl, R<2> is H or lower alkyl and A is H or SO3H) as a fluorine-contg. surfactant is added to the mixed soln. by 0.001-0.1wt.% of the amt. of the sulfuric acid. The surface tension of the mixed soln. is reduced, the wetting property to a body to be treated is improved and a treatment reaction such as cleaning or removal is accelerated.

While the wafers are brought into close contact, they are heat-treated in a wet oxidizing atmosphere at 800 deg.C or higher. The oxide films between them are united and an insulating film 24 is formed.

Title: Hollow poppet valve

Abstract: PURPOSE:To improve thermal conductivity and stirring property against low melting point metal so as to improve cooling performance and productivity of a poppet valve in which a hollow part is formed for enclosing low melting point metal by forming a columnar projection in the hollow part. CONSTITUTION:During running of an internal combustion engine, the valve head 2 of a hollow poppet valve 1 is exposed to combustion gas of high temperature. Then metallic sodium 10 enclosed in the hollow part 9 formed from the valve head 2 to the valve stem 5 is liquefied, stirred by reciprocating motion of the hollow valve 1, and repeatedly moved in the axial direction of the valve stem 6. As a result of this, the whole hollow valve 1 is thermally balanced, and thermal strain and the like of the valve head 2 is prevented. In the above- state constitution, a columnar projection 14 is formed from the inner lower face of the valve head 2 forward to the valve stem 6 side. By the use of the projection 14, thermal conductivity and stirring property against metallic sodium are improved.

Title: Video coder and video coding method
Inventor: FUJIE KEIICHIRO
IPC: H04N19/48
Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To put this method to practical use sufficiently by avoiding an image from being deteriorated and minimizing a delay in the case of replacing a part area of an image of an MPEG2 video stream with another video image. SOLUTION: In the case of coding a video image into a video stream VSm by the video coder, the image area is divided into two areas, that is, a replacement enable area (A1) and a replacement disable area (A2), and data of the area A1 are coded by using only data of the area A2 for reference data for motion detection. A replacement section 62 replaces a slice of a stream Sm in the area A1 generated by the coder with a replaced video image slice stored in a library 63. Moreover, the video coder applies intra-coding to the data of the area A1 to decode data of the area A1 only, overwrite the data on the image and encode the data.  Thus, a stream Sm is produced without decoding the stream Sm itself but while replacing the part of the stream with other video image (e.g. commercial CM) or a stream Sm on which a logo or the like is overwritten through decoding/encoding of the replaced area only.
