Brushes (20, 21) which come into slidable contact with slip rings (23, 24) having power feeding terminals (51, 53) electrically connected to a power feeding side include extending portions (32, 36) extending in the radial direction of a field core (3). These extending portions (32, 36) are bent in a direction away from a coil bobbin (12). The third bent portions (32c, 36c) located at the ends of the extending portions are electrically connected to the terminal portions (10d) of coil terminals. An outer diameter R1 of a mounting recess portion (3a) which stores a power feeding device (5) of the field core (3) is smaller than an inner diameter R2 of the coil bobbin (12). This makes it possible to position the mounting recess portion (3a) at a distance H from the coil bobbin (12) in the field core (3) in the arrow A direction, thereby reducing the size of the rotating coil type electromagnetic clutch (1) in the arrow A-B direction.
摘要:
A polyisocyanate production method that can allow effective use of hydrogen chloride produced secondarily in a polyisocyanate production process, while allowing reduction of environmental burdens, and a polyisocyanate production system for performing the polyisocyanate production method. After chlorine is allowed to react with carbon monoxide to produce carbonyl chloride in a carbonyl chloride producing reactor, the carbonyl chloride produced in the carbonyl chloride producing reactor is allowed to react with polyamine in an isocyanate producing reactor to produce polyisocyanate. Then, after hydrochloric gas produced secondarily in the isocyanate producing reactor is purified in a hydrogen chloride purifying column, the purified hydrochloric gas is oxidized in a hydrogen chloride oxidizing reactor to produce chlorine. Thereafter, the chlorine thus produced is supplied to the carbonyl chloride producing reactor from a chlorine resupply line, so that it is allowed to react with carbon monoxide to produce carbonyl chloride.

A leather is obtained by a process where a re-tanning agent is used which is constituted by synthetic tannin, resin and aluminum. The synthetic tannin is constituted by (a) condensation product of aromatic sulfonic acid with formaldehyde, (b) methylene cyclic polymer of aromatic sulfonic acid with hydroxy aromatic compound, and (c) glyoxal. The resin is constituted by (a) acrylic acid, methacrylic acid, acrylic acid ester or methacrylic acid ester polymer(s), and copolymer(s) thereof, and (b) polycondensation product of melamine with formaldehyde.
摘要:
A process for producing a composite of aluminum material and synthetic resin molding with high efficiency; and a stable fast composite exhibiting high peeling resistance and large mechanical strength. The process is characterized in that aluminum material (1) is anodized in electrolytic bath of phosphoric acid or sodium hydroxide to thereby form anodic oxidation coating (2) provided with innumerable pores (3) having a diameter of 25 nm or more made open in the surface thereof is formed thereon, and a synthetic resin mold (6) is coupled with the anodic oxidation coating (2) in such a condition that the portion (6a) of the synthetic resin molding (6) is intruded or anchored in the innumerable pores (3) of the anodic oxidation coating (2). By this process, composite (P) with the above properties can be easily obtained.

A method of manufacturing an electronic apparatus having a resist pattern provided over a substrate provided with a thin film transistor, the method includes the steps of forming by application a resist film over the substrate in the state of covering the thin film transistor, forming a resist pattern by subjecting the resist film to exposure to light and a developing treatment, and irradiating the resist pattern with at least one of ultraviolet light and visible light in a dry atmosphere in the condition where a channel part of the thin film transistor is prevented from being irradiated with light having a wavelength of shorter than 260 nm, wherein a step of heat curing the resist pattern is conducted after the irradiation with at least one of ultraviolet light and visible light.
摘要:
A variable valve timing apparatus includes a stopper piston which has an equalizing passage in an axial direction. Even if the engaging hole is filled with the oil, the equalizing passage enables the oil flows from an engaging hole to a holding hole when the stopper piston enters into the engaging hole. It is possible to form a vane as narrow as possible, and to enlarge a variable angular range. In addition, the stopper piston has both end faces which are substantially identical in surface area. Even if pulsation arises in oil pressure, pressures acting on both end faces of the stopper piston can be substantially cancelled and position of the stopper piston can be stabilized.

After a first copy request is received and copy operation from a copy source area to a copy destination area is activated, information indicating an update section is recorded when a data update of at least one of either the copy source area or the copy destination area is generated. When a second copy request is received, data in the copy source area corresponding to the update section is copied to the copy destination area, in accordance with the recorded information.
