A helically continuous projection 1a is formed around a sliding surface 1A of a sliding bearing 1 at a given pitch p. The surface roughness h of the sliding surface 1A, including the projection 1a, is chosen to be equal to or less than one-half the height H of the projection. This provides a sliding bearing 1 which exhibits an improved running-in performance.

A cell surface antigen determination method for determining an immunocyte having an immune antigen-antibody complex composed of an antigen and an antibody combined therewith in a liquid which contains immunocytes having various antigens and also containing many kinds of antibodies, and an apparatus used in this method. In accordance with the inventive method and apparatus, non-specific reactions are restrained so as to reduce the background without using a complement.
摘要:
A ground fish meat (surimi) is produced by bleaching raw fish meat with water in the presence of a quality-improving agent comprising calcium chloride, potassium chloride, or a mixture of sodium chloride with potassium chloride or calcium chloride in an amount of 0.01 to 3.0% of the total weight of the raw fish meat and the bleaching water. During the bleaching, the fish meat is forcibly stirred. Then, the thus bleached fish meat is ground to produce a surimi product.
摘要:
A Colpitts oscillator has an integrated circuit. The integrated circuit includes a transistor having an equivalent large size, a bypass capacitor connected between a collector of the transistor and a ground, a first feedback capacitor connected between a base and an emitter of the transistor, a second feedback capacitor connected between the emitter of the transistor and the ground, and an emitter follower connected to the emitter of the transistor. In a package, a stray reactance and a bonding wire are designed so as to agree with an element value and a Q value which can be used as parts of a resonator. A surface elastic wave resonator disposed outside the integrated circuit is connected between the base of the transistor and the ground. The oscillator is voltage controlled by a variable capacitance diode connected in series with the resonator.

An explosive composition containing micro-voids consisting of thermoplastic resin hollow microspheres coated with a thermosetting resin has a remarkably excellent low temperature detonability in a small diameter cartridge after lapse of a long period of time.
摘要:
An apparatus is disclosed which enables a controlled member (e.g. a workpiece retaining member in a jig) to be adjusted in position by extremely small amounts of linear displacement or angular rotation, with a very high degree of accuracy and static and dynamic stability. The apparatus is based on a servo system controlled by electrical signals and employs hydrostatic pads to support and move the controlled member.
摘要:
A multilayer glass structure constructed by joining the edge portions of a plurality of glass sheets by a sealant through spacers having an adsorbent filled therein. According to this invention, the adsorbent comprises a combination of a granular zeolite composed of a core of a synthetic zeolite/clay binder mixture containing the synthetic zeolite in an amount larger than its average content in the granular zeolite and a shell of a synthetic zeolite/clay binder mixture containing the clay in an amount larger than its average content in the granular zeolite, with granular activated carbon having on its surface 1 to 20% by weight, based on the activated carbon, of a coating of a synthetic resin latex. The adsorbent can effectively adsorb water vapor and the vapor of an organic solvent evaporated from the sealant, and prevent dew deposition on the glass surface. Moreover, it does not yield dust even when the glass structure is handled under severe conditions.
摘要:
Disclosed are spectacle frames or single parts thereof having a moderate heat distortion temperature, i.e. approximately 60.degree. to approximately 70.degree. C. The spectacle frames or single parts thereof are composed of a cured polyurethane prepared by the reaction of (1) a mixture of two types of diisocyanates represented by the following formulae (A) and (B): ##STR1## where R.sub.1 is an aliphatic hydrocarbon group of 1 to 12 carbon atoms and R.sub.2 and R.sub.3 are hydrogen or an aliphatic hydrocarbon group of 1 to 12 carbon atoms, ##STR2## where X is oxygen or an aliphatic hydrocarbon group having 1 to 5 carbon atoms, with (2) a polyhydroxy compound having a hydroxyl value of at least 150 and an average molecular weight of 300 to 5,000. The ratio in amount of the diisocyanate of type (B) to the total of the two types of diisocyanates (A) and (B) is 0.2-0.7 by mole.
