Title: Polishing method and polishing device
Inventor: SATO HIROSHI
IPC: B24B37/04
Filed: 1996-04-16
Abstract: PROBLEM TO BE SOLVED: To keep the uniform in-plane temperature of a polishing object and lessen a polishing irregularity at inside uniform temperature by holding the reverse side of the polishing object and polishing the surface thereof under the circulation of a fluid to the reverse side in such a state as controlled at constant temperature. SOLUTION: A fluid controlled at a constant temperature level is introduced to the center of a recess 23 from a nozzle 27 laid through a rotary shaft 24 via communication holes 25, and cools the reverse side of a wafer 1, while being diffused over the whole of the recess 23. Regarding the reverse side of the wafer 1, a part near a center has the highest temperature in this case, and the fluid introduced from the nozzle 27 first exchanges heat with the high temperature part. As a result, the part of the wafer 1 near the center is cooled, while the temperature of the fluid rises, due to the heat exchange. Also, as the fluid is diffused over the whole of the recess 23 under a gradual temperature rise, the outer end of the wafer 1 having relatively low temperature is cooled with the fluid having temperature raised to a suitable level.

Title: Metal o-ring for use in radial sealing
Inventor: KOUNO TAKAYUKI
IPC: F16J15/08
Filed: 1979-07-24
Abstract: PURPOSE: To protect a sealing surface against damags at the time of attaching and detaching an O-ring and to enable to attach the O-ring in place and detach the same out of place smoothly, by constituting an O-ring through combination of a resilient ring serving directly as seal and a rigid ring for guiding the deformation of said resilient ring.  
     CONSTITUTION: An O-ring 4 consists of a resilient ring 1 serving directly as seal and a rigid ring 2 for guiding the deformation of the ring 1. The resilient ring 1 has a diameter slightly larger than that of the rigit ring 2, and as the material for the resilient ring 1, titanium alloy, ordinary spring material, phosphor-bronze, nickel silver, etc. are suited for use. On the other hand, any hard material such as martensite stainless steel, ferrite stainless steel and Inconel can be used for the material of the rigid ring 2. The O-ring 2 is placed, for instance, between a support plate 6 and a pressure plate 7 in a pipe 5 and can function as seal since the resilient ring 1 is slided along the surface of the rigid ring 2 while increasing its diameter when a force F is acted to the pressure plate 7.

Filed: 1989-04-13
Abstract: PURPOSE:To prevent troubles caused by wear of a photosensitive drum and heating of continuous paper by permitting one driving means to retreat the fixing roller of a printer using continuous recording paper and a transfer charger. CONSTITUTION:When a laser printer is ready for printing, a gear motor not shown here is driven to retreat a backup roller 81B for a pair of fixing rollers 81, and a fan hold paper 20 is separated from the heat roller 81A. Moreover, the corona charger 81 of a transfer part 7 is retreated from a transfer position. Consequently, trouble caused in such a way that the heat roller 81A heats the same place of the fan hold paper 20 while printing is awaited can be prevented. In addition, trouble caused by the contact of the photosensitive drum 1 can be prevented when printing starts and when the photosensitive drum 1 rotates with the fan hold paper 20 stopped.

Title: Method for analyzing minute amount of element in metal and semiconductor
Inventor: KUWABARA ATSUKO
IPC: H01J37/252
Filed: 1993-04-21
Abstract: PURPOSE:To measure a minute amount of elements accurately by heating a cleaned metal or semiconductor to a specified temperature in a surface analysis device which is not higher than a speific pressure, measuring the surface segregation concentration of a minute amount of different kinds of elements included in the metal or semiconductor, and determinig the concentration of different kinds of elements from the relationship between the equilibrium segregation concentration and the bulk concentration. CONSTITUTION:A sample is cut in the shape of a disc. The surface of the sample is mirror- finished and polished before being etched and vacuum annealed. The sample is then set on a heating stage and treated by ion sputtering for cleaning. The sample is quenched while being heated in vacuum or after being heated. The concentration of a minute amount of atoms segregated on the surface of the sample is measured at normal temperatures. The degree of vacuum is approximately not higher than 10<-7> Torr and the heating temperature is 1/4 to 4/5 the melting point of the sample ( deg.K), namely, not lower than 323 deg.K. When the surface equilibrium segregation concentration is Xs, the bulk concentration is Xb, and the temperature is T deg.K, Xs/(1-Xs)=Xbexp(A/T) is held. In order to obtain the constant A, the equilibrium concentration of a sample whose concentration is already known is preliminarily measured at three levels of temperatures. When the temperature T and the surface equilibrium segregation concentration Xs are measured, the bulk concentration is consequently detected.

Abstract: PURPOSE:To prevent an unpractical analysis from being executed by deciding on the connection-possibility between two neighboring numerals in respective numerals constituting a numeral string when the numeral string is analyzed. CONSTITUTION:For an input character string stored in an input character string storing means TBUF, a numeral dictionary NUMDIC is retrieved by a numeral retrieval means, and a numeral in the input character string is found, and the information of thus found numeral is stored by a numeral storing means NUMSTR. By arraying the numerals stored by said numeral storing means one by one from the head of an input, a numeral string is generated. At such a time, the connection-possibility between the last numeral of yet-formed numeral string and the numeral to be added succeedingly is decided on by a numeral-numeral connection decision means. When the possibility of connection exists, the numeral string with consecutive numerals is newly stored in the numeral string storing means. In such a way, any analysis which is unlikely to be necessary can be prevented from being executed.
