摘要:
An improved tapered roller bearing in which a shoulder at a small diameter end side of an inner race has been eliminated. A shoulder portion for maintaining a state of engagement between an inner race and a cage for holding tapered rollers at circumferentially equally spaced positions after assembling, is formed at an outer peripheral portion of a large diameter side of the inner race. Furthermore, projections for engagement with the shoulder portion are formed in positions not hindering the assembling of the tapered rollers at the large diameter side of the cage.

A sealed type rolling bearing includes an another race, an inner race, a plurality of rolling elements, at least one retainer therefor, and at least one seal plate. The bearing is sealed with grease seal, and grease in the bearing is prevented from flowing at a high rate by means of an annular projection extending radially inwardly from the retainer defining a small gap defined between the projection of the retainer and the inner race.

摘要:
A bearing comprising inner and outer rings formed of a metal and a plurality of balls formed of calcined carbon which has self-lubricating properties and hardness higher than that of the inner and outer rings and has been baked beforehand at a temperature higher than a working temperature of the bearing so as to prevent the outgassing even when used in the circumstances of high temperature.

摘要:
Dry powders of amino acids which exhibit great oral meltability and solubility, may be produced by spray drying a hydrous liquid of amino acids to produce a powder of amino acids, where the hydrous liquid of amino acids is prepared into the form of microfine liquid droplets in the presence of trehalose for spray drying, to obtain a powder having a mean particle size of 0.1 μm to 15 μm, as well as granulating and drying during the spray drying or after the spray drying, to obtain a granulated powder having a mean particle size of 20 μm to 1,000 μm.
摘要:
In order to provide a spray dry method capable of producing a dry powder retaining the savor and flavor of a raw material and having solubility without any thermal deterioration, at a mass scale, a method for producing a dry powder keeping savor and flavor from a hydrous liquid material containing a savory and flavorful component and, preferably, a hygroscopic component by spray drying is disclosed, the method including spray drying the hydrous liquid material at the microfine liquid droplet state in gas atmosphere at the outlet temperature of a spray dryer at 20 to 90° C. and the outlet relative humidity of 1% RH to 40% RH, to prepare a dry powder of a mean particle size of 0.1 μm to 15 μm.
摘要:
A coating composition comprising (A) a polymer obtained by polymerizing (a1) one or more unsaturated acid anhydrides or unsaturated carboxylic acids and (a2) one or more other unsaturated monomers copolmerizable therewith, and (B) at least one compound selected from one or both of (b1) a compound group comprising amino-acids, compounds having one or more carboxyl groups in the molecule, compounds having both hydrophobic group and hydrophilic group in the molecule, chelate compounds, hydroxyl- or acetyl-substituted carboxylic acid esters, ion-exchangeable layer clay minerals and powers of inorganic materials which have been made lipophilic with an organic material, and (b2) a group of compound which is crystallizable and selected from polyether compounds, polyester compounds, polyether-polyester compounds, olefinic glycol compounds, acrylic esters, methacrylic esters and polycarbonate compounds, is useful for preparing an antifouling coating composition by mixing with a copper compound.
摘要:
A multilayer capacitor includes first and second internal electrodes that are opposed to each other so as to generate an electrostatic capacitance and have a capacitance generating portion functioning to generate the electrostatic capacitance, terminal connecting portions connected to corresponding external terminal electrodes, and extended portions connecting the capacitance generating portion to the terminal connecting portions. The extended portions are narrower than the capacitance generating portion and the terminal connecting portion and are curved in the direction of their thickness so as to provide a longer effective length. The multi-terminal capacitor is capable of increasing an ESR without adding a separate additional element.
