Abstract: An electromagnetic relay includes a contact that includes a fixed contact and a movable contact, a permanent magnet provided on the peripheral side of the contact, and a non-magnetic body. The movable contact is displaceable in a first direction to move toward the fixed contact and in a second direction to move away from the fixed contact. The permanent magnet has a polarity direction perpendicular to the first and second directions. The non-magnetic body faces toward the direction of a Lorentz force that acts based on the permanent magnet in a direct electric current flowing through the contact.

Abstract: An electromagnetic relay includes: a main body including: a first cover; an electromagnet having a first terminal extending toward the outside from a bottom surface of the first cover; and a contact portion that opens and closes according to a magnetic attractive force of the electromagnet, and has a second terminal extending toward the outside from the bottom surface of the first cover; a cable line drawn out to the outside of the electromagnetic relay; and a printed circuit board that fixes the cable line to at least one of the first terminal and the second terminal by dip soldering, and electrically connects the cable line to the at least one of the first terminal and the second terminal.

Abstract: Technology for controlling image display according to the state of a viewer wearing eyeglasses to view 3D images is provided. When an inclined angle of eyeglasses is in a predetermined range, an image display device alternately displays a left-eye image and a right-eye image. When the inclined angle of the eyeglasses exceeds the predetermined range, the image display device does not switch the left-eye image with the right-eye image. For example, the image display device displays 2D images. Optical shutters of the eyeglasses are synchronized with the left-eye image and the right-eye image. When the image display device does not switch the left-eye image with the right-eye image, the optical shutters are both open.

Abstract: The present invention provides a process for producing an antireflection film comprising applying, using a slot die, a coating solution onto a web which is backed up by a back-up roller and runs continuously to form at least one layer which has a thickness of 200 nm or less in a dried state and has a refractive index lower than that of the web. The slot die has an edge lip downstream of the running web which has a land length along the running web is 30 to 100 ?m, and the space between the edge lip of the slot die upstream of the running web and the surface of the web is set to be 30 to 120 ?m larger than the space between the edge lip of the slot die downstream of the running web and the surface of the web.

Abstract: An industrially and economically advantageous process for the preparation of a TBH-HX using starting materials which are cheaply available and are easy to handle, maintaining a high yield. A tertiary butyl hydrazine hydrohalogenide is prepared by reacting a hydrazine hydrohalogenide with a methyl tertiary butyl ether in the presence of an acid.

Abstract: Disclosed is a process for the preparation of monomethylhydrazine which comprises reacting hydrazine monohydrochloride with methanol in the presence of hydrazine dihydrochloride or methyl chloride and recovering free monomethylhydrazine from the formed monomethylhydrazine hydrochloride.According to this process, monomethylhydrazine can be prepared at a high selectivity very easily while controlling formation of by-products.

Abstract: Dewatering of sludge is accomplished by adding an organic fibrous material having the bulk specific gravity increased by being pressed or being wetted with water and a high molecular weight flocculant to the sludge, adjusting the resulting flocs to a diameter of not more than 1 mm, and subjecting the flocs to vacuum or pressure filtration.

Abstract: Disclosed is a process for the preparation of a tertiary butyl hydrazine hydrohalogenide, which comprises reacting a hydrazine salt of a hydrohalogenic acid with tertiary butanol in the presence of a hydrazine dihydrohalogenide or a hydrogen halide.Also disclosed is a process for the preparation of tertiary butyl hydrazine, which comprises reacting a hydrazine salt of a hydrohalogenic acid in the presence of a hydrazine dihydrohalogenide or a hydrogen halide, neutralizing the formed tertiary butyl hydrazine hydrohalogenide by an alkali, distilling the neutralization product and recovering free tertiary butyl hydrazine.

Abstract: Inorganic acid salts of tertiary butyl hydrazine such as hydrochloride or hydrobromide of tertiary butyl hydrazine, useful for production of azine compounds are substantially stoichiometrically produced by reaction of inorganic acid salts of hydrazine such as hydrochloride or hydrobromide of hydrazine with tertiary butyl halides such as chloride or bromide at a molar ratio of the tertiary butyl halides to inorganic acid salts of 1:7-10 at a reaction temperature of 90.degree. to 110.degree. C. for 40 to 100 minutes.

Abstract: Methylhydrazines are produced in high yield by reaction of trimethylanilinium halide with hydrazine or monomethylhydrazine at a reaction temperature of 80.degree. to 130.degree. C. for at least 3 hours.Methylhydrazines are useful compounds in the fields of chemical industry, such as manufacturing pharmaceuticals or agricultural chemicals, and space weapon industry.
