Title: Instrument for collecting insulating oil
Inventor: KATAYANAGI ATSUSHI
IPC: G01N1/10
Filed: 1996-04-04
Abstract: PROBLEM TO BE SOLVED: To effectively reduce a pressure difference between the outside air and interior of a container due to the change in volume of an insulating oil, by setting cocks at free ends of tubes connected to both sides of a sample bottle and providing one tube with a sack. SOLUTION: Tubes 2, 6 are fixed by 4 at both ends of a sample bottle 1 capable of storing most of a collected insulating oil, thereby making it easy to collect the insulating oil from a device to the like. Moreover, a cock 5 is set in the vicinity of a front end of each tube 2, 6 to shut an opening part of the tube thereby to prevent the collected insulating oil from leaking. A shrinkable sack 3 is fitted at a part of the tube 2. The sample bottle 1 is generally formed of glass or the like. Even when a volume of the collected insulating oil is changed due to a temperature change, the volume change is accepted at the tubes 2, 6 and sack 3 because most of the insulating oil is in the sample bottle 1. A surface area per unit length of the tube is increased by the sack 3. In other words, a volume ratio of a variable part to the volume change of the insulating oil is increased. Accordingly, a pressure difference of the outside air and interior of the container is reduced.

Title: Etching method for silicon wafer
Inventor: FUKAGAWA HIROSHI
IPC: H01L21/677
Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of a stained film during transportation by, during transportation of a silicon wafer from an etching bath to a rinsing bath, allowing the wafer to rotate faster than its revolving speed in the etching bath, so that an etching liquid is shaken off from a wafer surface and a holding device. SOLUTION: A wafer is etched at specific rotation mode for etching work during etching work, and 1-2 seconds before a target etching amount is worked, it is automatically switched to a transportation-specific rotation mode and then transported from an etching bath to a rinsing bath. The wafer is rotated faster at transportation than at etching, and the etching liquid on the surface of the wafer is shaken off by centrifugal force so that etching will not proceed during transportation. Then, after transported to the rinsing bath, the wafer is put in the rinsing bath at low speed for rinsing with pure water, so that the pure water may disperse quickly on the surface of wafer. Thus, occurrence of a stain film on the surface of wafer is prevented during transportation.
