A material for dentistry having a low odor, a low stimulation and a proper dough stage time is here disclosed which is prepared by blending a monomer selected from the group consisting of (meth)acrylate compounds represented by the general formula ##STR1## R.sub.1 is a hydrogen atom or a methyl group, each of R.sub.3, R.sub.6 and R.sub.10 is an alkyl group, and each of R.sub.2, R.sub.5, R.sub.8 and R.sub.9 is an alkylene group) and (meth)acrylate dimers.
摘要:
Disclosed is a dental composition comprising a (meth)acrylic ester compound as the principal component and containing a polymerization initiator, which is characterized by having incorporated therein a grafted rubber obtained by polymerizing at least one ethylenically unsaturated monomer in the presence of a rubber. This dental composition can be cured to yield a cured product having excellent strength properties and, therefore, is particularly useful in applications such as a molar restoration material and a denture base resin.

Provided is an additive masterbatch having excellent storage stability (agglomeration resistance), which also has reduced surface tackiness despite comprising a low-melting-point resin additive at a high concentration. The additive masterbatch of the present invention is characterized by comprising, with respect to 100 parts by mass of (A) a polyolefin resin, 65 to 300 parts by mass of (B) a resin additive having a melting point of not higher than 80° C.; and 0.8 to 24 parts by mass of (C) a benzotriazole-based ultraviolet absorber.

Even when temperature sensors (12, 13) used in a device for warming a battery (1) being not in use by using a battery-driven heater (2) have failed, the battery (1) is prevented from freezing. Based on a battery temperature (Tb) and an outside air temperature (Ta), times (Δt1 to Δt8) during which Tb will decrease down to a warming start temperature (Tb_start) are each set to the next controller startup time (Δt). A controller (9) is started up every Δt, at t2, t3, and t4, and checks whether Tb

A fixing device for thermally fixing an unfixed image formed on a recording sheet by passing the recording sheet through a fixing nip. The fixing device has a heat-generating endless belt that includes: a resistive heat layer that generates heat upon receiving electric current; and a pair of electrode layers each disposed along a different one of widthwise edges of the heat-generating endless belt. The resistive heat layer has (i) reduced thickness portions each along a widthwise edge thereof and (ii) a middle portion between the reduced thickness portions. Each reduced thickness portion is thinner than the middle portion and connected to the middle portion with a wall surface upright in a direction perpendicular to the rotation axis of the heat-generating endless belt to define a stair shape. Each electrode layer is disposed on the resistive heat layer to be in contact with a corresponding one of the wall surfaces.

When warming-up of a battery is in progress (S12), a battery charge state at the warming-up start time of the battery is set to a battery hold capacity SOChold (S14, S15), and a charge power for the battery is controlled so that a battery charge state SOC is kept at SOChold. When a present time is in a timer charge reservation time (S11), the charge power for the battery is controlled so that SOC becomes a full charge state SOCfull (S17). Even if SOC has a tendency to temporarily decrease due to a rapid increase of heater consumption power just after start of warming-up of the battery, by keeping SOC at SOChold (SOC=SOChold) SOC can reach a full charge state as intended during the timer charge reservation time. A proportion of charge using low-priced midnight power is increased to a maximum then running cost can be suppressed.

A laminated body manufacturing apparatus for manufacturing an annular laminated body in which each layer is defined by a plurality of segments is provided with a feeding unit that sequentially feeds a plurality of parts to be processed on a band-like sheet material to a predetermined processing position; a processing unit that separates the segment from each part to be processed by a shearing processing in the processing position; and a laminating unit that receives the segment that is separated and lowered onto the plurality of segments that are lowered and defining one layer in advance and that rotates the received segment by a predetermined angle in a circumferential direction of the segment, each time when the shearing processing is performed, so as to place the sequentially lowered segment in a position to define the laminated body.
摘要:
Manufacturing processes for phase change memory have suffered from the problem of chalcogenide material being susceptible to delamination, since this material exhibits low adhesion to high melting point metals and silicon oxide films. Furthermore, chalcogenide material has low thermal stability and hence tends to sublime during the manufacturing process of phase change memory. According to the present invention, conductive or insulative adhesive layers are formed over and under the chalcogenide material layer to enhance its delamination strength. Further, a protective film made up of a nitride film is formed on the sidewalls of the chalcogenide material layer to prevent sublimation of the chalcogenide material layer.
