Disclosed is a biaxially oriented film for electrical insulation having even better withstand voltage characteristics than before together with excellent film-forming properties. The biaxially oriented film for electrical insulation of the invention is a film that includes a substrate layer containing a crystalline thermoplastic resin as a main component. The substrate layer contains a phenolic stabilizer in an amount of 0.001 wt % or more and 3 wt % or less based on the weight of the substrate layer. The phenolic stabilizer is an alkylenebisamide-type hindered phenol.

A wide protection range can be ensured by extending the flying distance of fire-extinguishing agent particles electrified and sprayed from a head. A water-based fire-extinguishing agent is pressurized and supplied to an electrification spray head 10 installed in a protection area A via a pipe, the jetted particles of the fire-extinguishing agent are electrified and sprayed from the electrification spray head 10. The electrification spray head mixes and sprays the fire-extinguishing agent having a comparatively small particle size included in a range from 30 μM to 200 μm by a small-particle jetting nozzle 38a and the fire-extinguishing agent having a comparatively-large particle size of 200 μm to 2000 μm by a large-particle jetting nozzle 38b, thereby carrying the group of the fire-extinguishing-agent particles having the small particle size by the air current caused by spraying the group of the fire-extinguishing-agent particles having the large particle size.

A hydraulic shock absorber enables its piston rod to be locked near its minimum length position and allows the locked condition to be visually confirmed easily. A cap member is secured to a distal end portion of a piston rod extending from a cylinder part, and a dust cover is secured to the cap member. A lock member is secured to an end of the cylinder part from which the piston rod extends to the outside. The lock member is cut and bent upward to form engaging portions. The cap member is cut and bent downward to form engaging pieces and windows. With the piston rod contracted to near its minimum length position, the cap member is rotated to engage the engaging portions and the engaging pieces with each other, thereby locking the piston rod. The engaged condition of the engaging portions and the engaging pieces can be visually confirmed through the windows.

An object of the invention is to provide such an oriented polyester film that has a constant thickness, and is excellent in dimensional stability at a high temperature and dimensional stability to temperature change in a working temperature range. The invention relates to an oriented polyester film containing as a major component of a substrate layer polyethylene-2,6-naphthalene dicarboxylate, being stretched at least in one direction, and having a film thickness of from 12 to 250 μm, wherein (1) a coefficient of linear thermal expansion αt at a temperature of from 30 to 100° C. is from 0 to 15 ppm/° C. in both longitudinal and width directions of the film, and (2) a thermal shrinkage rate at 100° C. for 10 minutes is 0.5% or less in both longitudinal and width directions of the film.
摘要:
A seat weight measuring apparatus capable of securely withstanding large force due to large load, such as force in the event of a vehicle collision, applied to a vehicle seat. Normally, a small force is applied to a rear pin bracket and the sleeves through which a pivot bolt is inserted do not substantially collide with the inner peripheries of holes. As a large force is applied to the rear pin bracket, a stopper bolt collides with a base frame and the rear pin bracket collides with the pivot bolt. The large force exerted on the rear pin bracket is shared and borne by portions of the frame thereby reducing the localized stresses in the frame.

A vacuum processing apparatus includes a transfer chamber filled with a gas to have an upper limit of a target pressure range, a gas supply system connected to a gas supply source to supply the gas into the transfer chamber, a gas exhaust system for releasing the gas from within the transfer chamber, first and second vacuum chambers connected to the transfer chamber, first and second gate valves interposed between the transfer chamber and the vacuum chambers, which selectively permit the transfer chamber and the vacuum chambers to communicate with each other and a transfer mechanism for transferring a target object from the first vacuum chamber to the transfer chamber via the first gate valve and for transferring the target object from the transfer chamber to the second vacuum chamber via the second gate valve. An opening/closing valve is provided in the gas supply system for selectively supplying the gas from the gas supply source into the transfer chamber, a gas loading space being defined upstream of the opening/closing valve to permit the gas having a volume and pressure set in accordance with the upper limit of a target pressure range to be stored in the gas loading space when the opening/closing valve is closed.
