Title: Apparatus and method for measuring temperature
Inventor: AKAMA YOSHIAKI
IPC: G01K11/12
Filed: 1998-10-22
Abstract: PROBLEM TO BE SOLVED: To noncontactingly measure temp., without previously providing a fixed hole pattern, by having reflecting surfaces formed on an object to be measured and computing the temp. irradiated with a laser beam on a pair, based on the spacing of interference fringes generated by the reflected light of the laser beam. SOLUTION: When an embossed pattern (a pair of recesses) formed at an irradiating position on a wafer W surface is irradiated with a laser beam L from a laser oscillator 21, diffracted lights appear from the pair of recesses and an interference fringe B appears at their intersection point. A CCD camera 24 captures the interference fringe B to obtain an interference fringe image. As the temp. of the wafer W rises then, the substance which forms the wafer W expands to broaden the embossed pattern spacing, resulting in a narrowed fringe spacing of the interference fringe image. That is since there is a fixed correlation between the temp. rise of the wafer W and the spacing reduction of the interference fringe B, the temp. change can be obtained by detecting the change of the spacing of the interference fringe B.

Title: Purification of ethanol
Inventor: FUJITA YOSHIHIRO
IPC: C07C67/00
Filed: 1986-12-19
Abstract: PURPOSE:To efficiently obtain high-purity ethanol from an ethanolic solution containing ethyl acetate, propyl acetate, etc., by carrying out ester interchange of an acetic acid ester with methanol and separating ethanol from methyl acetate and other alcohols by distillation. CONSTITUTION:Methanol 3 is added to an ethanolic solution 1 containing one or more acetic acid esters, e.g. ethyl acetate, propyl acetate, butyl acetate, etc, which are hardly separated from ethanol by ordinary distilling operation since an azeotropic mixture the ethanol is formed. Thereby ester interchange is carried out with the above-mentioned esters in an ester interchange column 2 to convert the esters into readily separable methyl acetate and alcohol. The resulatant product is then distilled in a column 5 for removing methanol and methyl acetate and a crude ethanol column 11 to efficiently and economically afford the aimed high-purity ethanol 12. The acetic acid esters, e.g. ethyl acetate, etc., which are not subjected to ester interchange are readily separated from the methyl acetate together with the methanol and recirculated through the ester interchange step. The formed methyl acetate has high utilization value as a solvent or raw material for ethyl acetate.

Title: Syringe needle
Inventor: YAMADA HIROSHI
IPC: A61M5/32
Filed: 1992-10-13
Abstract: PURPOSE:To reduce pain and to facilitate treatment after use by constituting a syringe needle main body of a synthetic resin. CONSTITUTION:As a syringe needle main body A is made of a synthetic resin, it is thermoplastic and a thin rod-like hollow body can easily be prepd. by means of an extruder. In addition, a needle A made of the synthetic resin exhibits hardening property by cooling and it is possible to perform sterilization and to keep asepsis by using an exclusive cooling container for the synthetic resin needle. In addition, as moisture condensation occurs caused by moisture in air by the time when the needle is taken of the cooling container and it pierces into a human body, it is slippery and has a little resistance to reduce pain. In addition, as incineration of synthetic resin is easy at a low temperature and complete burning is possible, the problem on aftertreatment can be solved. Therefore, there is no possibility that infectious accident caused by bacteria occurs as is the case with the conventional metallic syringe needle.
