The object is to make it possible to pass an electric current to the object of polishing with a stable current density distribution up to the end point of polishing, to use the same plating apparatus, cleaning apparatus and other apparatuses as those conventionally used, and to carry out the conventional manufacturing process flow. A substrate (1) provided with a metallic film (2) and a opposite electrode (3) are disposed oppositely to each other with a predetermined distance therebetween in an electrolytic solution, and an electric current is passed to the metallic film (2) through the electrolytic solution by an anode (4) set out of contact with the metallic film (2), so as to electropolish the metallic film (2). Simultaneously with the electropolishing, wiping is conducted by sliding a pad on the metallic film.

Apparatus for measuring and analyzing the swing of a baseball player. The apparatus includes devices for emitting a plurality of spaced light beams projected in directions to be intersected by the swing plane of a bat and a corresponding plurality of light receiving elements arranged to receive light beams reflected from the bat. Signals received by the light receiving elements are collected and supplied to a processing apparatus and the results of this processing are displayed on a display unit which provides indication of angle, speed, level, etc. of the swing. The information may also be provided to a printer. The apparatus indicates whether the swing is performed normally and if it deviates from normal indicates the error involved.
摘要:
A microwave oven cooking apparatus including a magnetic card reader from which control data may be read to control cooking operations. Data may first be input by the operator from a keyboard control panel. This data is stored in a first memory. Upon completion of the cooking operation, if successful, the operator depresses a control transferring the data stored in the first memory to a second memory from which it is read onto and stored on a magnetic card. The magnetic card can be then reinserted into the card reader for later input of the same cooking operational data.

The present invention relates to a composition for an optical material capable of suppressing generation of inhomogeneity called “stria” in polymerization, in particular, generation of striae in a lens having high optical power or a surface with high radius of curvature, and more specifically relates to a composition for an optical material, comprising: a stabilizer having a mass ratio of dibutyltin dichloride to monobutyltin trichloride of 97.0/3.0 to 100.0/0.0; an episulfide compound; a polythiol compound; and a polymerization catalyst for the episulfide compound.
摘要:
A problem to be solved by the present invention is to provide an episulfide compound efficiently from an epoxy compound with no need of a measure against odor or corrosion, or a neutralization step. The present invention solved the above-described problem by a method for producing an episulfide compound in which an epoxy compound and a thiourea are reacted with each other in the presence of an ammonium compound.
摘要:
The present invention has an object of providing, for example, a composition for optical materials which contains a polythiol that can be predicted and assessed, in a stage prior to polymerization/curing, as being clouded or not clouded after polymerization/curing, and thus can be determined as being good or defective. According to the present invention, the above-described object is achieved by, for example, a composition for optical materials which comprises a polythiol that exhibits an initial turbidity of 0.5 ppm or less and a turbidity of 0.6 ppm or less after the storage at 50° C. for 7 days, and an episulfide. Namely, an optical material made from a composition for optical materials which contains a polythiol satisfying the above turbidity requirements can be prevented from clouding to exhibit excellent transparency.
