Disclosed is a food sterilization method capable of heat-sterilizing foods uniformly by heating steam irrespectively with a shape of an apparatus. The food sterilization method includes introducing the food into the inside of the heat-sterilizing chamber through the opening of the opening and closing part; discharging the air in the inside of the heat-sterilizing chamber through the air discharging part, close contacting the sealing cover and the heat-sterilizing chamber by absorption force of the air to seal the inside of the heat-sterilizing chamber, and then reducing a pressure in the inside of the heat-sterilizing chamber; closing the air discharging part, supplying the steam from the steam supplying part to the inside of the heat-sterilizing chamber to close contact the sealing cover and the opening of the opening and closing part by a pressure of the steam and thereby seal the opening and closing part and the inside of the heat-sterilizing chamber, and then heat-sterilizing the food introduced into the inside of the heat-sterilizing chamber by the steam supplied from the steam supplying part and at the same time, discharging some of the steam in the inside of the heat-sterilizing chamber through the steam discharging part during the heat-sterilization; closing the steam supplying part, and discharging the steam in the inside of the heat-sterilizing chamber through the steam discharging part; and taking the food out of the heat-sterilizing chamber through the opening of the opening and closing part.

A heat treatment method includes a substrate holder that holds a plurality of substrates at predetermined vertical intervals and is carried into a heat treating furnace for performing a predetermined heat treatment on the substrates. The substrate holder has two holder constituting bodies each having a plurality of columns and substrate holding sections. One of the holder constituting bodies holds the substrates at a first, vertically adjacent distance so that their front surfaces face each other, while the other of the holder constituting bodies holds the substrates at a second, vertically adjacent distance so that their back surfaces face each other wherein the second distance is smaller than the first distance to ensure uniformity of the heat treatment. At least one of the holder constituting bodies moves in the vertical direction to change the positions of the holder constituting bodies relative to each other.

A method for detecting defects on a specimen includes mounting a specimen on a table with which is movable, obliquely projecting a laser as a line onto a surface of the specimen, detecting with an image sensor an image of light formed by light reflected from the specimen and passed through a filter which blocks scattered light resulting from repetitive patterns formed on the specimen, processing a signal outputted from the image sensor to extract defects of the specimen, and a displaying information of defects extracted by the signal processor.

A defect inspection method includes radiating an illumination slit-shaped beam having lights substantially parallel to a longitudinal direction to a substrate having circuit patterns in a direction inclined at a predetermined gradient relative to the direction of a line normal to the substrate and inclined at a predetermined gradient on a surface with respect to a group of main straight lines of the circuit patterns with its longitudinal direction oriented almost perpendicularly to a direction of a movement of the substrate. Scattered light reflected by a defect such as a foreign particle existing on the illuminated substrate is received and converted into a detection signal by using an image sensor, and defect judging is effected of an extracted a signal indicating a defect such as a foreign particle on the basis of the detection signal output.

A process for manufacturing high-purity o-toluic acid from a partial oxidation product of o-xylene is disclosed. o-Toluic acid is widely used as a raw material for agricultural chemicals, medicines, polymerization initiators, and the like. Depending on its use, 99% by weight or more purity is demanded for o-toluic acid. Hitherto, o-toluic acid having purity of higher than 99% by weight could not be obtained by fractionation, and purification by fractional crystallization was used. Fractional crystallization is, however, and expensive operation and not only gives a low yield of product but also results a large amount of waste water. The process disclosed herein gives an economical, commercial way to obtain high purity o-toluic acid. In summary, a process for the manufacture of high purity o-toluic acid which comprises: subjecting an oxidation product of o-xylene to distillation to remove therefrom low boiling point components such as unreacted o-xylene and benzoic acid, and high boiling point components, of which the major component is o-methylbenzyl o-toluate, thus obtaining crude o-toluic acid, treating said crude o-toluic acid with ammonia of an amount 1 to 1.2 mol equivalent of o-phthalic acid contained in said crude o-toluic acid, and subjecting the product thus treated to distillation is disclosed.
