To form a surface shape of an etching object in a short time at low cost, and to make the surface shape to be formed highly accurate. An apparatus for forming a surface shape includes a resist forming device for forming a resist of a predetermined shape on a predetermined surface of the etching object, and an etching device for performing etching to the predetermined surface of the etching object on which the resist is formed. The resist forming device includes a resist attaching device for attaching a resist material to a predetermined surface of the etching object, and a laser irradiating device for irradiating a laser beam to the attached resist material so as to remove a part thereof to a thereby shape it into a predetermined shape.

A phase-locked loop circuit includes a first PFD (phase detector) and a second PFD. The first PFD accepts an input clock signal CLK and a feedback clock signal FBCLK, and supplies its positive output to a charge pump. The second PFD accepts an inverted signal NCLK of the input clock signal CLK and the feedback clock signal FBCLK, and supplies its negative output to the charge pump. The phase-locked loop circuit outputs the clock signal whose phase differs from the phase of the input clock signal by 90 degrees.

A blow molded container for high purity liquid chemicals having (1) an inner layer formed of a high purity resin comprising at least one member including olefinic polymers of ethylene, propylene, butene-1, 4-methyl-pentene-1, hexene-1 or octene-1 and copolymers of ethylene and olefins other than ethylene; (2) an intermediate layer of a solvent-barrier resin including polyamides, polyvinyl alcohols, poly(ethylene-co-vinyl alcohols), polyesters and polyphenylene oxides; and (3) an external layer formed of a light-shielding substance-containing resin composition. The lowest absorbance of the total layers of the container is greater than 2.0 measured at a wavelength of not more than 400 nm. The total layers also have an absorbance that does not exceed 1.62 measured at a wavelength of 600 nm. The container is especially good for holding photoresist liquids.

A shadow mask includes a mask body having a principal mask surface with electron beam passage apertures, a skirt portion, and long and short axes, and a mask frame attached to outside the skirt portion. The mask frame has a coefficient of thermal expansion higher than that of the mask body. The skirt portion includes first and second tongue portions situated on the short and long axes, respectively. Each of the first and second tongue portions is fixed to the mask frame. The mask body is formed to fulfill relations given by (Ca·Wb)
摘要:
A casing accommodates therein three primary colors of chip LEDs. The casing is disposed in a through hole of a plate-shaped light guide. The chip LEDs are mounted on both surfaces of a substrate so as to face a peripheral surface of the through hole (light incident surface). The casing is made of a transparent synthetic resin accommodating therein the substrate and the chip LEDs. The light emitted from the chip LEDs can be introduced directly into the light incident surface of the light guide. The three primary color of chip LEDs are controlled so that a desired color and intensity of light can be efficiently introduced into the light guide.

In the case where an object to be ground is ground by mounting a horizontally elongated jig onto a grinding head and by bringing the object into contact with a grinding surface of a grinding disk being driven and rotated, the attitude of the grinding head is controlled by an adjust ring that is in surface contact with the grinding surface of the grinding disk while moving the grinding head, the horizontally elongated jig holding thereon the object that has a plurality of thin film magnetic heads arrayed thereon. Thereby, the flatness of the object is improved and variations in the throat heights of many magnetic heads formed on the object to be ground are reduced by allowing the attitude of the object to be controlled with a grinding surface of a grinding disk as a reference.
