Abstract: It is an object to provide a method for efficiently producing an N-alkylmaleimide-based polymer that has an excellent optical characteristic, excellent heat resistance, and excellent mechanical strength. A method for producing an N-alkylmaleimide-based polymer in accordance with an aspect of the present invention includes using an oil-soluble radical polymerization initiator to carry out suspension polymerization, in an aqueous medium in the presence of at least one dispersant selected from the group consisting of a nonionic compound having no hydrogen bonded to oxygen or nitrogen, a polyacrylate salt, and a polyalkylene glycol, with respect to a monomer mixture consisting of 20% by weight to 100% by weight of N-alkylmaleimide and 0% by weight to 80% by weight of other copolymerizable monomers, the N-alkylmaleimide being represented by the following general formula (1): where R represents a C1-C12 linear alkyl group, a C3-C12 branched alkyl group, or a C3-C6 cyclic alkyl group.

Abstract: A sound generation device for a vehicle, the sound generation device being installed in a vehicle which travels using an electric-powered motor as a power source, includes a sound control apparatus which sets a plurality of frequencies corresponding to a motor rotation speed and generates a synthetic sound signal indicating a synthetic sound including sounds at the plurality of frequencies and a speaker which outputs the synthetic sound based on the synthetic sound signal generated by the sound control apparatus, and the sound control apparatus sets an increase amount of an output of a sound in a low frequency band large compared to an increase amount of an output of a sound in a high frequency band in a frequency range of the synthetic sound in accordance with an increase in a motor torque value.

Abstract: A vehicle sound generation device includes a controller that generates a sound signal representing a sound and sets the localization of the sound, and left and right front speakers and left and right rear speakers that output sounds corresponding to the sound signals for which localization has been set by the controller, in which the controller sets the localization of the sounds based on the change amounts (such as the pitch rate, the torque change amount, the roll rate, and steering angular speed) per unit time of the physical quantities correlated with a driving operation by the driver of the vehicle so that the sound image of at least part (low frequency component) of frequency components of the sound is located toward the wheel where the ground load is increasing according to the driving operation.

Abstract: Provided is a packaging that is for a medical adhesive sheet, results from housing a medical adhesive sheet resulting from a peelable liner being pasted to the surface to which an adhesive agent layer has been formed of a resin film having the adhesive agent layer, and is characterized by: the medical adhesive sheet being folded in a manner so that the surface to which the peelable liner is provided is the inner surface and the surface to which the resin film is provided is the outer surface; the folded medical adhesive sheet being sandwiched between packaging sheets; and the packaging sheets being sealed at the ends thereof.

Abstract: A navigation apparatus includes a storage unit, an acquiring unit, a comparing/identifying unit, an updating unit, and a control unit. The navigation apparatus stores data required for the navigation operation in a plurality of areas and also acquires the data from an external recording medium. The data stored in the plurality of areas is updated based on a comparison with the acquired data to identify which is the most recent data. At least while the updating of data is in progress, the data that is not in the process of being updated is used to perform navigation operation.

Abstract: A changer device includes a playback drive for playing back tracks recorded on a disk. The changer device also includes: a memory for storing playback signals of each of the tracks recorded on the disk; a recording-history information management memory for storing recording-history information of the tracks related to the playback signals stored in the memory; and a memory control unit for allowing the memory to store in order the playback signals of the tracks played back by the playback drive, and for allowing the recording-history information management memory to store the recording-history information of the tracks related to the playback signals stored in the memory.

Abstract: A thermoplastic shaped resin article may include, for example, a shaped base material and a thermoplastic resin sheet. A discontinuous metal film may be disposed on one surface of the resin sheet. The base material may be adhered to the resin sheet so that the metal film faces the base material. As a result, shaped resin articles may be prepared that have a metallic appearance and transmit visible light.

Abstract: A control circuit of a solenoid actuated pump includes an energizing means for energizing a solenoid of the solenoid actuated pump, a detecting means for detecting the electrical energy of a power supply for supplying the electrical energy to the energizing means, and a processing unit for comparing the value of the electrical energy detected by the detecting means with a predetermined value to be supplied to the solenoid and supplying a control signal to the energizing means so as to adjust the detected value of the electrical energy to the predetermined value.

Abstract: An inflator which generates gas and heat as the inflator is actuated. The inflator includes an identifying member. The identifying member is provided on the inflator so as to permit the identification of an unactuated state and an actuated state of the inflator on the basis of heat generated during the actuation of the inflator.

Abstract: A rotary valve which includes a valve sleeve having a cylindrical internal cavity and a plurality of axial grooves formed on the wall surface of the internal cavity; a valve spool fitted in the internal cavity of the valve sleeve and rotatable relative to the valve sleeve for controlling flow of a pressurized fluid through the valve; an annular groove formed at least at one end of the valve sleeve and having a diameter larger than that of the internal cavity; a bush fitted in the annular groove and having a hole of the same diameter as the internal cavity of the valve sleeve; a seal material interposed between engaging surfaces of the bush and annular groove; chamfered surface formed at the outer corner edge of the bush; and an annular thin-wall portion formed at the end of the valve sleeve and bent radially inward to retain the bush in the annular groove.
