In an optical data recording/reproducing apparatus for performing write and read operations of data by irradiating laser light onto an optical data recording medium, in order to reduce noise of a semiconductor laser, an HF oscillator is provided to superpose an HF current on a drive current to be applied to the semiconductor laser. The HF oscillator is housed in a conductive shield case together with the semiconductor laser. An LC low-pass filter is also provided in a signal line connecting the components inside and outside the shield case to prevent undesired radiation of the HF current. A write drive line and a read drive line of the semiconductor laser are separated in the shield case, and the write drive line is disconnected from the HF oscillator in at least a read mode.

For preventing a semiconductor substrate from a heat attack, a method of rapid annealing using a lamp unit for a heat radiation comprises the step of preparing a semiconductor substrate having a multiple-layer structure and a vessel having an annealing chamber where the lamp unit is placed, the vessel is associated with an inert gas supplying system operative to supply a high-pressure inert gas to the annealing chamber, and the above step is followed by the steps of placing the semiconductor substrate in the annealing chamber, supplying the high-pressure inert gas to the annealing chamber so as to create a high-pressure inert ambient within a predetermined range and activating the lamp unit for the heat radiation so as to heat up the semiconductor substrate, so that the heat radiation is decreased in intensity by virtue of the high-pressure inert ambient.

A process for producing arsenous acid is disclosed. The reactants include an organic solvent containing 5 valent arsenic, a reducing agent and an additional component selected from the group consisting of water and an aqueous solution. The organic solvent containing 5 valent arsenic contacts and reacts with the reducing agent in the presence of the water or aqueous solution in order to directly produce arsenous acid from the organic solvent containing 5 valent arsenic. The process is a simple and economical process for producing arsenous acid.

A pattern of a character, numeral or symbol on an optical mask is selected in accordance with the designation by a character designator and irradiated with light from a printing light source. The light is converted into a light of the pattern of the designated character, numeral or symbol by a optical mask, the pattern being of a size ranging from about 20 to about 500 .mu.m, and the converted light reaches a thin layer of a dispersion imaging material formed on a recording medium to cause at least dispersion of the thin layer, thereby to print the pattern of the designated character, numeral or symbol. A recording medium support and the position of irradiation of the recording medium with the converted light are moved by a drive relative to each other, so that characters, numerals and symbols can be printed on the recording medium one by one. The characters, numerals and symbols printed on the recording medium in the region including the recording medium irradiating position are optically displayed by a projector during the printing operation.

An image processing apparatus includes the following elements. An image storing section stores a plurality of images related to time information. A feature extracting section extracts feature amounts of each image stored in the image storing section. An image selecting section that selects at least one of images included in each overlap portion set of several or all of the images, stored in the image storing section, on the basis of the feature amounts associated with the respective images included in the overlap portion set, the overlap portion set including overlap portions of several or all of the images overlapping with respect to shooting time. A digest-image generating section generates a digest image of the images stored in the image storing section on the basis of the selected images.

Systems and methods for correcting a location of a terminal are provided. In various aspects, a processor in a position correction apparatus may associate a reference position with the terminal, and determine a range for the terminal based on the reference position. The processor may also associate a second position with the terminal, and determine if the second position associated with the terminal is outside the determined range for the terminal based on the reference position. Upon a determination that indicates that the second position is outside the determined range, the processor may correct the second position to a corrected position associated with the terminal.

The measurement of a flaw height in a thick welded portion of a stainless steel specimen, which is difficult to perform by the TOFD method, can be conducted with more ease, with higher accuracy and in a shorter time than in the case of using tip echo techniques. In addition, it is possible to reduce variations in measurement results among individual inspectors.An ultrasonic wave 21 is launched by a transmitting probe 1 into a specimen 20 in a direction oblique to a flaw 24 to generate diffracted waves at the tip 25 of the flaw 24, then a diffracted wave 22 propagating upward directly from the flaw 24 and a diffracted wave 23 propagating upwardly of the flaw 24 after once reflected off the back 27 are received by a receiving probe 2 disposed above the flaw 24, and the height of the tip of the flaw 24 from the back 27 is measured from the propagation time difference between the received diffracted waves.
