Abstract: A release agent for plastic contains the following components (A) to (E) and has an average particle size of 200 nm or less: (A) 100 parts by mass of an organopolysiloxane having a viscosity at 25° C. of 100 to 100,000 mm2/s; (B) 0.1 to 15.0 parts by mass of one or more anionic surfactants; (C) 1.0 to 30.0 parts by mass of a polyoxyethylene alkyl ether; (D) 0.5 to 15.0 parts by mass of a polyoxyethylene sorbitan fatty acid ester; and (E) 50 to 100,000 parts by mass of water. The release agent is an organopolysiloxane emulsion having excellent dilution stability and mechanical stability and favorable wettability, and hardly cracking plastic.

Abstract: An amino-modified silicone emulsion including: (A) an amino-modified silicone represented by formula (1), having a viscosity at 25° C. of 200 to 100,000 mPa·s, and an amine equivalent of 1,000 to 20,000 g/mol; (B) 5 to 100 mass % of a nonionic surfactant relative to the mass of component (A); (C) 50 to 100 mol % of lactic or acetic acid relative to a number of moles of amino groups of component (A); and (D) 85 to 10,000 mass % of water relative to the mass of component (A), where an increased amount of each of (D4), (D5), and (D6) is less than 3,000 ppm relative to the mass of component (A) when the emulsion has been stored at 25° C. for 6 months. Thus, the emulsion is provided wherein octamethyl cyclotetrasiloxane etc. hardly increase over time, and provides excellent smoothness and softness when blended in a hair cosmetic or a fiber treatment agent.

Abstract: A memory having a plurality of storage blocks, and a memory control unit, are included, and each of the storage blocks is partitioned into a management data area and an actual data area. The management data area stores therein writing-in-progress management data indicating that writing of actual data has started, validity management data indicating that the writing of the actual data has been completed, and pre-erasure management data indicating that stored actual data have been brought into an erasable state. The memory control unit determines, based on a storage state of the management data, the storage block storing therein the latest data.

Abstract: A serial communication device includes: a data transfer unit configured to repeat storing a predetermined unit of data, received by a receiving unit, in a receiving buffer and transfer data to a storage unit when data of a predetermined size is accumulated in the receiving buffer; a counting unit configured to count one of the number of times the predetermined unit of data is stored and an amount of data accumulated; a monitoring unit configured to monitor a count value counted by the counting unit; and a data identifying unit configured to determine that a current interval is a non-communication interval during which a sending source does not send data if the count value remains unchanged for a predetermined time and identify first data, received after the determination of the non-communication interval, as beginning data of a sequence of data including a plurality of pieces of data.
