Patent JP-H04125928-A (JP)
Title: Manufacture of semiconductor device
Inventor: OTAKE TOSHIHIRO
IPC: C23F1/00
Filed: 1990-09-17
Abstract: PURPOSE:To prevent etching irregularity of a processed surface, by bringing etching liquid into contact with a wafer rear in the state that the central part of the wafer is deformed into a downward convex curved surface. CONSTITUTION:A wafer 1 is sucked by a wafer chuck 14 provided with a sucking surface which constitutes a downward convex curved surface, thereby deforming the central part of the wafer into a downward convex curved surface. Etching liquid is circulated by a liquid supplying means 13. Since the diameter of an aperture of a processing tank 11 is made larger than that of the wafer 1, the etching liquid 2 overflows the tank 11 and is stored in an outer thank 12. From above the processing tank 11, the wafer 1 is made to descend until the rear comes into contact with the etching liquid 2 and to rotate. At this time, bubbles of reaction gas attaching to the rear are moved toward the higher middle part and eliminated.

Filed: 1991-09-02
Abstract: PURPOSE:To obtain the title resin suitable for e.g. silicone flexibilizer effective for the stress reduction, heat resistance raising and mechanical strength enhancement for semiconductor element sealers by condensation between a phenol novolak resin bearing methylol groups at both the ends and an allylphenol. CONSTITUTION:Firstly, a phenol novolak resin of formula I (R1 is 1-4C alkyl; n is >=2) is reacted with formaldehyde in a solvent in the presence of an alkali catalyst to produce a phenol novolak resin bearing methylol groups at both the ends of formula II. Thence, this resin is condensed with an allylphenol of formula III. (R2 is 1-4C alkyl or alkoxy) in a solvent in the presence of an acid catalyst, thus affording the objective telechelic novolak resin of formula IV.

Title: Perturbator operating method for synchrotron
Inventor: KAMISAKA MITSURU
IPC: H05H13/04
Filed: 1990-09-17
Abstract: PURPOSE:To increase the incident efficiency in an inflector and perform the increase in the accumulated current value in a storage ring by decreasing a kick-quantity of a perturbator as the accumulated current in the storage ring increases when injecting new particle beams from the outside into the storage ring via the inflector. CONSTITUTION:By kicking an accumulated particle beam circulating in a storage ring 22 of a synchrotron 20 into the inflector 18 side with a perturbator 25, the kick-quantity of the perturbator is decreased as the accumulated current in the storage ring 22 increases when injecting new particle beams from the outside into the storage ring 22 via the inflector 18. Thus, increase in the accumulated current value can be performed, no matter how big the particle beam diameter in the storage ring 22 is, since the collision of the particle beam against the wall in the inflector 18 is unlikely to occur. Consequently, compared with in the case of the incidence with uniformly small kick-quantity the average incidence efficiency can be improved, and the accumulated current value can be increased compared with in the case of the incidence with uniformly large kick-quantity.

Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To provide the printing method of a printer system capable of quickly setting a printing mode even by a beginner. SOLUTION: When a user excites property, the property dialog of a printer driver is displayed, and simultaneously an auxiliary message is displayed. The displayed auxiliary message is a dialog in the format of the choice of three functions, that is, 'immediate start of printing', 'retrieval', and 'end'.

When the user selects the 'start of printing' or 'end' with the auxiliary message, the processing of the auxiliary message is ended. Also, when any processing is not performed or processing unsuitable for the selection is performed by the user, the waiting state is immediately obtained. Then, when the user selects 'retrieval', a retrieving processing is operated (S32).

Inventor: HAAS THOMAS DR
IPC: C07C29/132
Filed: 1999-09-01
Abstract: PROBLEM TO BE SOLVED: To reduce the acetal or ketal in an aqueous phase reaction mixture containing a high-content of alcohol by catalytically hydrogenating the acetal or ketal with a heterogenous catalyst that is acidic or neutral at room temperature thereby further reducing the acetal or ketal without decomposition of alcohol. SOLUTION: Acetals other than formal or ketal in an aqueous phase reaction mixture containing at least 10 moles of monohydric or polyhydric alcohol per mole of acetal or ketal are reduced by catalytically hydrogenation in the presence of a catalyst of a noble metal on activated carbon heterogeneously at 80-250 deg.C, preferably 100-180 deg.C, under a hydrogen partial pressure of 0.5-30 MPa. This process is particularly suitable for removal of the acetals other than formal or ketals of α-hydroxycarbonyl compounds or β-hydroxycarbonyl compound, particularly removal of 1,3-dioxolane derivatives, particularly 1,3-dioxane derivatives.

Abstract: PROBLEM TO BE SOLVED: To correct the deviation of an image formation surface and to keep high optical performance even though there is a temperature difference among plural lens groups by detecting the temperature information of every specified lens group by a temperature detection means. SOLUTION: The temperatures T1 to T4 of the respective lens groups are detected through detection circuits 24, and 29 to 31 from temperature sensing resistances 12, and 26 to 28 functioning as the temperature detection means arranged near the respective lens groups and inputted in a control circuit 13. Next, the detected temperatures T1 (k) to T4(k) of the respective lens groups are compared with a reference temperature T0 so as to obtain a difference between them. By reading a focal distance and lateral magnification for the temperature factors A1 to A4 of the respective lens groups and the reference temperature T0 of a PR 104, a temperature correction value is calculated. Based on the calculated value, the extending amount of the PR 104 is calculated. Based on the calculated data, a variator 102 and the PR 104 are respectively driven.

Title: Plasma etching method
Inventor: KUBO KENICHI
IPC: H01L21/302
Filed: 1986-10-20
Abstract: PURPOSE:To prevent the damage such as dielectric breakdown and the like generating on the element of a substrate by a method wherein, after the necessary etching has been completed, the etching operation is stopped by reducing electric power gradually. CONSTITUTION:The quantity of electric power supplied to a high frequency electrode 2 is controlled by restricting the power coming from a high frequency power source 20 using a power source controlling device 21. To be more precise, the specific electric energy, having no etching capability while an on-ramp operation is being performed, is supplied and after said operation has been completed, application power is raised to the high frequency power energy necessary to perform an etching treatment, and then a necessary etching treatment is performed while the above-mentioned state is being maintained. After the etching treatment has been completed, the application power energy is reduced gradually, the supply of power is stopped, and the entire etching operation is finished. When the etching treatment is completed as above- mentioned, the electric charge accumulated on the element of the substrate can be released little by little while the etching treatment is being performed by reducing the applied power gradually without turning OFF the power source suddenly, and the damage such as dielectric breakdown and the like generating on the element can be prevented.

Abstract: PURPOSE:To drive a system with a power unit with low rated current by providing a control circuit which controls power supply to a functional block, and a control instruction circuit which instructs control in the control circuit. CONSTITUTION:The control instruction circuit 2 judges whether or not the power supply to an arbitrary functional block should be performed corresponding to the mutual operating status of the functional blocks 42, 45-47, and instructs the control to the control circuit 1 which controls the power supply based on the above judgement. Therefore, the rated current of the power unit observing from the whole system can be reduced to a low level by prohibiting the power supply when no power supply to the arbitrary functional block 42 is required. In such a way, the power unit with low rated current can be obtained, and accordingly, the miniaturization and the reduction in weight of a terminal, etc., can be attained.
