摘要:
Disclosed is a resin laminate having a surface layer excellent in antistatic properties, scratch resistance, and transparency. Also disclosed is a method for producing the resin laminate with a high productivity. Further disclosed is a transfer film for use in the production of the resin laminate. The resin laminate comprises a resin shaped article, an antistatic layer containing a π-electron conjugated conductive polymer and at least one resin selected from a polyester resin, a polyurethane resin, a polyesterurethane resin, an acrylic resin, and a melamine resin on at least one surface of the shaped article, and a cured coating film layer obtained by curing a curable resin on the antistatic layer. The method for producing the resin laminate preferably comprises the steps of forming the cured coating film layer and the antistatic layer on a mold using a transfer film, carrying out cast polymerization of a raw material for a resin, and detaching the resin laminate from the mold after the polymerization is completed.

摘要:
An encrypted content and its encryption key under a copy right use condition of prohibiting a copy by the device having received a content are stored, and the encrypted content is copy-transferred with another device through the network, and at the same time, the encryption key is transferred through the network, so that it is stored in either one of the devices.Even when a high definition television broadcast signal received with a copy-once taken as a copy right use condition is recorded, an access flag that controls the presence or absence of the reproduction of the broadcast content for each broadcast content is provided. When an original broadcast content is transcoded into a low resolution, and is transfer to another device, its access flag is turned on, thereby making the reproduction possible.

A method of producing an acrylic resin plate, comprising a step of adding 0.001 to 1 part by weight of a polymerization initiator having 10 hours half life temperature of 80° C. or more and 0.015 to 0.2 parts by weight of cyclohexadiene or terpenoid-based compound into 100 parts by weight of a mixture composed of an alkyl methacrylate having a C1-4 alkyl group and a poly-functional (meth)acrylate to give a polymerizable mixture, and a step of polymerizing said polymerizable mixture; an acrylic resin comprising 3 to 30 wt % of an alkyl methacrylate unit having a C8-20 alkyl group, 2 to 35 wt % of a mono-ethylenically unsaturated monomer unit containing an alkyl methacrylate unit having a C1-4 alkyl group and 35 to 95 wt % of a poly-functional (meth)acrylate unit; an acrylic resin plate made of the resin and production process the same, and a transparent electrode plate for touch panel and a touch panel having them.
摘要:
An automotive passenger restraint and protection apparatus includes an electric retractor having a motor for retracting and protracting a seatbealt. The apparatus also includes an airbag driving device, a pretensioner, a speed detecting device, and a controller. The controller controls at least one of the actuation time or expansion pressure of an airbag by the airbag driving device, actuation time of the pretensioner, a force of the pretensioner for retracting the seatbelt, and a force of the seatbelt driving device for retracting the seatbelt, based upon the speed of protraction of the seatbelt. The controller controls the airbag driving device to shorten the actuation time of the airbag when the speed of protraction of the seatbelt is greater than a predetermined value, and prolongs the actuation time of the airbag when the detected speed of protraction of the seatbelt is lower than the predetermined value.
摘要:
This invention provides a resin for light guiding plates which retains physical properties as acrylic resins such as transparency and exhibits good processability with minimum scorching of an edge during polishing or cutting. This resin for light guiding plates is made of a polymer prepared by polymerizing a mixture comprising 100 parts by weight of a polymerizable material consisting of 91 to 100% by weight of methyl methacrylate and 0 to 9% by weight of a monofunctional acrylate, and 0.01 to 2 parts by weight of a polyfunctional (meth)acrylate. The resin preferably comprises 0.01 to 1000 ppm of a diffusing agent.
摘要:
An automotive passenger restraint and protection apparatus for an automotive vehicle having doors, and a seatbelt, for restraining an occupant of the automotive vehicle by the seatbelt to protect the occupant includes an electric retractor having a motor for retracting and protracting the seatbelt, a controller for controlling the motor, and a door opening/closing detector for detecting opening and closing of a predetermined one of the doors. When the door opening/closing detector detects the opening of the predetermined one of the doors, the controller controls the motor to carry out retraction of the seatbelt at a higher speed than when the door opening/closing detector detects the closing of the predetermined one of the doors.
摘要:
A take-up spindle is used to wind thereon a webbing of a seat belt system. The take-up spindle has a shaft defining a slot through which the webbing may extend, a sleeve fitted externally on the shaft and defining a first slot and a second slot therethrough, and an insert filling out the first slot. Each of the first and second slots of the sleeve permits insertion of the webbing therethrough. The second slot of the sleeve serves to guide the webbing out of the sleeve.
