A surface-treating agent mainly includes three constituents: a water-soluble polymer; a surface sizing agent which is a copolymer of a styrene type monomer and an anionic monomer and which mainly includes a water-soluble copolymer containing 20 to 80 weight % of the styrene type monomer; and a surface sizing agent which is a copolymer of an olefin type monomer and an anionic monomer and which mainly includes a water-soluble copolymer containing 20 to 80 weight % of the olefin type monomer. The surface-treating agent is coated and dried on a base paper for offset printing.

An oxygen sensor device consisting a cylindrical tube of a ceramic solid electrolyte having an oxygen ion conducting property, a reference electrode formed on an inner surface of the cylindrical tube, and a measuring electrode formed on an outer surface of the cylindrical tube at a position at least opposed to the reference electrode, wherein a ceramic layer is formed on the outer surface of the cylindrical tube, the ceramic layer having an opening portion for exposing the surface of the measuring electrode and incorporating a heat-generating member therein, the heat-generating member being buried surrounding the opening portion. The oxygen sensor device as a whole has a cylindrical shape relaxing the concentration of thermal stress and exhibiting excellent thermal shock resistance. With the heat-generating member being buried near the sensing portion, the sensing portion is heated up to a predetermined activating temperature within short periods of time exhibiting an excellent sensor response.
摘要:
A technique for reducing active area encroachment (birdsbeak) by using a polysilicon hard mask combined with both wet and dry etch for the isolation nitride. This process forms a thinner layer of nitride adjacent the openings for oxide growth, which reduces stress at the silicon/nitride interface. The advantages include control over birdsbeak, reliable gate oxide quality, low junction leakage current, an improved active area, improved isolation, low peripheral junction leakage, and higher field transistor threshold voltage.

Methanol is produced by reacting carbon monoxide and hydrogen in the presence of a Raney copper catalyst containing 80 to 99.9 wt. % of copper in a solvent. The catalysts employed in the present invention showed a much higher activity even under the conditions of a low temperature in methanol production, than any of the known catalysts. The process of the methanol production may eliminate necessity for recycling an unreacted synthesis gas into the reaction system, and makes it feasible to conduct methanol synthesis at a lower pressure than conventional processes.

The present invention comprises a ROM 5 for storing a password, a password check section 9, a RAM 10 for storing a number of password mismatch occurrences, a radio section 1, and a central processing unit 12 for controlling the memory, radio and checking sections. When a password for rewriting individual information is input from an external terminal 50, the central processing unit 12 requests the password check section 9 to check the password with a password stored in the ROM 5. When the both passwords don't match, a password can be repeatedly re-input until the password matches and the number of password mismatch occurrences is stored in the RAM 10.
摘要:
Each of the inner and outer rings of a non-retainer type rolling bearing has a wear-resistant solid film of a fluorine-containing synthetic resin formed on its track surface. The solid film carries a very small amount of grease having a low vapor pressure, e.g. fluorine-containing grease, as an effective lubricant for the inner and outer rings, and the rolling elements held therebetween, while the solid film is also restrained from producing dust. The amount of the grease does not exceed 5% of the volume of the open space in the bearing.

The object of the invention is to provide a digital voice transmission system which suppresses, even when a long voice message is to be transmitted, an increase of the transmission capacity of a radio channel and, even if a drop of a division of divisionally transmitted voice compression data occurs, it is prevented that the voice data becomes difficult to hear. Data including a radio apparatus identification code, a message identification code, a division number, a digital voice compression data identification code, text message length information, a text message, reproduction time information, a system possession voice data identification code possessed by the transmission side irrespective of whether or not radio transmission is employed, system possession reproduction time information, a voice start code and digital voice compression data are transmitted. The voice compression data are divided with a length equal to an integral number of times that of a compressed voice data unit and are allocated to radio frames.
摘要:
A water solvent extraction degreasing method capable of reducing degreasing time without consideration of abrupt decomposition/vaporization and swelling caused by heat. An organic binder is removed from a molded product that is produced by a powder material mixed with the organic binder and this organic binder contains at least one water-soluble organic compound and at least one water-insoluble thermoplastic resin. The degreasing step of this method includes a water solvent extraction step for extracting the water-soluble organic compound from the organic binder contained in the molded product, using water as a solvent.

The reflecting surface of an aspherical reflector assumes, in the main scanning plane, a curve represented by Z(Y)=AY.sup.2 +BY.sup.4 +CY.sup.6 +DY.sup.8 +EY.sup.10 where Z is the coordinate along the optical axis, Y is the coordinate in the direction that is perpendicular to the optical axis and is included in the main scanning plane, and A to E are coefficients satisfying A.times.C>0. The reflecting surface assumes, in any of auxiliary scanning planes arranged in the main scanning direction, a circular arc that establishes a conjugate relationship in geometrical optics between the deflecting face of a deflector and the scanning surface.
