摘要:
The object of the present invention is to provide a flame-retardant resin composition which has a high heat resistance, superior impact resistance and superior flame-retarding properties. The present invention provides a flame-retardant resin composition which is characterized by the fact that said composition contains (A) a polycarbonate type resin, (B) a silicone resin constructed from siloxane units expressed by the formula RSiO1.5 (T units) and siloxane units expressed by the formula R3SiO0.5 (M units), or a silicone resin constructed from T units, M units and siloxane units expressed by the formula SiO2.0 (Q units) (R indicates an unsubstituted or substituted monovalent hydrocarbon group with 1 to 10 carbon atoms), and (C) an anti-drip agent, and the aforementioned composition contains 0.1 to 9 parts by weight of the abovementioned silicone resin (B), and 0.01 to 10 parts by weight of the abovementioned anti-drip agent, per 100 parts by weight of the abovementioned polycarbonate resin (A).
摘要:
A manufacturing method for transparent polyester/polycarbonate compositions using equipment for manufacturing polycarbonates or polyesters by the melt polymerization method comprises a manufacturing method wherein polyester or polycarbonate resin is added to a polymerization vessel or to the outlet side of a polymerization vessel of polycarbonate or polyester manufacturing equipment, or a manufacturing method. The polyester or polycarbonate resin is added to a polymerization vessel in which the polymerization reaction is substantially complete, or to the outlet side of a polymerization vessel, or to the pelletization apparatus of the manufacturing equipment for polycarbonates or polyesters and provides high productivity for manufacturing transparent polyester/polycarbonate compositions with superior impact strength as well as solvent resistance.
摘要:
A strut mount allows a sufficient pre-compression to be applied to a rubber member without impairing the retaining force for the rubber member, thereby achieving improved durability of the rubber member. A pre-compression member (4) has an outer diameter that is smaller in the distal end side than in the proximal end side, and is press-fitted into the inner peripheral surface of an inner tube member (1).

A process of making a chlorinated hydrocarbon through a thermal dehydrochlorination step in which an unsaturated compound represented by the following general formula (2) is obtained by thermally decomposing a saturated compound represented by the following general formula (1). CCl3—CCl2-mHm—CCl3-nHn (1) CCl2═CCl2-mHm-1—CCl3-nHn (2) (in the above formulas, m is 1 or 2, and n is an integer of 0 to 3.).
摘要:
A slide action type hinged-lid package (2) includes an inner case (6) having a lid (4), and an outer body (8) slidably accommodating the inner case. The outer body has an opening (46) formed through a front wall thereof (40) and allowing the inner case to be partly exposed, and a contact piece (48) provided at the rear edge of an upper open end thereof (38) and extending toward the interior of the outer body. The inner case has a reinforcing member arranged on the inside of a front wall thereof (14) which is exposed through the opening, and a strip (34) connected to the rear part of the lid and capable of engaging with the contact piece. When the inner case is slid up relative to the outer body, the engagement between the strip and the contact piece causes the lid to open and also regulates the amount of sliding of the inner case.
摘要:
An auto laser power control circuit is provided which improves the response of the optical output level of a laser diode in accordance with variations in the operation mode. In an auto laser power control circuit for comparing a voltage corresponding to the optical output from the laser diode which emits a light in accordance with a supplied driving current with a reference voltage, and controlling the driving current so as to reduce the difference at the time of the steady operation, by controlling a switch connected between the input and output terminals of an operational unit which compares the voltage corresponding to the optical output from the laser diode and the reference voltage, the driving current to the laser diode is controlled with a smaller time constant upon the start such as a transition of from a read operation mode to a write operation mode as compared with the time of the steady operation.
摘要:
A vehicle alternator output rectifier instrument in which mesa structure Zener diodes, formed by diffusion of impurity on a P-type silicon substrate, are used as rectifier elements which are used in rectifier circuits for rectifying an alternate current output of a vehicle alternator. Since the vehicle alternator output rectifier instrument employs the above Zener diodes, this rectifier instrument can endure high temperature circumstances, considerably reduce a reverse leakage current to thereby prevent a battery voltage from being discharged and reduce a radio noise to thereby reduce a bad influence exerted upon an electronic device serving as a load.
