Title: Manufacture of semiconductor device
Inventor: MATSUNO KIMIE
IPC: G03F7/20
Filed: 1992-08-04
Abstract: PURPOSE:To inhibit a resist scattered by foaming from adhering on a wafer by a method wherein an air flow, which turns from the inside of the surface of the wafer to the outside, is generated and the peripheral part of the wafer is exposed. CONSTITUTION:When the peripheral part of a wafer is exposed, a cup 5 is mounted in such a way as to encircle a wafer stage 3 and a scattered resist is sucked through a suction hole 6 in the bottom of the cup, whereby an air flow, which turns from the inside of the surface of the wafer to the outside, is generated. Thereby, even if foaming of a resist is caused, the scattered resist is sucked in the air flow and is removed outside of the wafer. At this time, it is also possible that the form of the cup is changed into various kinds of forms and a form to help so as to suck efficiently the scattered resist can be decided in a test manner. Thereby, in the exposure of the peripheral part of the wafer, the resist scattered by foaming can be inhibited from adhering on the wafer.

Title: Heat-insulating plate for induction heating coil
Inventor: AMAO NAGAFUMI
IPC: H05B6/36
Filed: 1997-07-15
Abstract: PROBLEM TO BE SOLVED: To prevent the heat-insulating performance of an heat-insulating plate from being deteriorated by getting covered with descaling water and by the deposit of scale, and improve its heating efficiency. SOLUTION: In a non-water-cooling heat-insulating plate that protects an induction heating coil used to heat inductively a heated metallic material to be transferred from the radiated heat from the heated material, a heat-resistant layer 1 that faces to the heated material and is composed of a composite of small piece materials of heat-resistant materials such as aluminum titanate or the like having a high heat- resistant and water-proofing properties, and a heat-insulating layer 2 having a high heat-insulating property that comes in contact with the heating coil are laminated so as to form a multilayer structure. Thereby, its total thickness can be reduced to half as much as a conventional one and the distance between the heating coil and the heat-insulating plate can be made smaller so that the heating efficiency can be improved.  Since the stress caused by rapid heating and cooling is absorbed into the fine cracks of the heat-resistant layer so that the heat-insulating plate is not broken, the radiated heat from the heated material is screened by the heat-resistant layer and thereby, the thermal deterioration of both the heat-insulating layer 2 and the coil can be prevented.

IPC: G01N30/26
Filed: 1994-08-31
Abstract: PURPOSE: To selectively change the holding time for specified component by adding boric acid to moving phase of ion chromatograph even under the condition where respective conditions are kept constant. CONSTITUTION: Relating to an analysing method for specific ion in sample by feeding the sample to an ion chromatograph column 6 at movement phase 7, the elution position of hydroxy acid group representing coordination characteristic against boric acid is selectively changed by adding the boric acid to the movement phase 7. In short, with a liquid feeding pump 1, the movement phase 7 is fed. The movement phase 7 contains, for example, p-hydroxy henzoic acid. By introducing the sample containing multiple negative ions here from a sample introduction device 3, such small univalent negative ion as held in the column 6 is eluted at first, and then, vibalent negative ion which is held strongly is eluted.  When hydroxy acid is injected into the movement phase 7 doped with boric acid, negative ion type compound is produced; thus, hydroxy acid is eluted as one zone at the time when presence ratio against the compound ion is reflected.
