A material for an organic electroluminescent device including an imine derivative represented by the following formula (Ia) or (Ib),wherein Y1 to Y4 are independently a carbon atom or a nitrogen atom; R1 to R4 are independently hydrogen, an alkyl group, an aryl group, a heterocycle, a halogen atom, a fluoroalkyl group or a cyano group; and R1 and R2, or R3 and R4 may be bonded together to form a ring.

A heating roller (21) includes a heat generating layer (22) that generates heat by electromagnetic induction, a heat insulating layer (23), and a supporting layer (24), which are provided inwardly in this order. The supporting layer (24) is formed of a material having a specific resistance of 1 x10<-5 >Omegam or higher. Therefore, even when the heat generating layer (22) has a thickness smaller than a skin depth, i.e. a thickness defined by a flow of an induction current, so that magnetic flux penetrates the heat generating layer (22) and even reaches the supporting layer (24), heat generation of the supporting layer (24) under an eddy current can be suppressed. Thus, the heat generating layer (22) can be decreased in thermal capacity, and heat generation of the supporting layer (24) is suppressed, so that only the heat generating layer (22) can be heated efficiently. As a result, a warm-up time can be reduced. Further, breakage by heat of, for example, bearings supporting the heating roller (21) can be prevented.

A thermal type flow sensor measures a flow rate of a fluid by means of a heat resistive element having a temperature dependency. The sensor is comprised of: plural heat resistive elements used for a flow rate measurement; and a driver circuit for controlling a current applied to these heat resistive elements to cause their heating. The driver circuit is configured to sense a resistance change of a lower-temperature side heat resistive element among the plural heat resistive elements and to control the current to be applied to the plural heat resistive elements in accordance with a sensed value of the lower-resistance's variation.

The invention relates to a method and device for separating and recovering mercury. By cutting off both ends of a lamp tube of a waste fluorescent lamp and peeling off a phosphor film formed on the inner surface of the lamp tube, phosphor powder containing mercury is recovered. Adding an organic reducing agent to the recovered phosphor powder and heating it to perform dry heating reduction treatment to vaporize and separate mercury from the phosphor powder. This vaporized mercury is condensed and recovered.

A polyacetal resin composition is composed of a polyacetal resin and a polycyclic aromatic carboxylic acid hydrazide which may have a substituent. With respect to 100 parts by weight of the polyacetal resin, the ratio of the polycyclic aromatic carboxylic acid hydrazide may be about 0.001-20 parts by weight. The above-mentioned polyacetal resin composition can also contain at least one selected from the group consisting of antioxidants, heat-resistant stabilizers, processing stabilizers, weather-resistant (light) stabilizers, impact resistance modifiers, slipperiness modifiers, colorants and fillers. kind. The resin composition improves the stability of the polyacetal resin and suppresses the occurrence of formaldehyde.

An oxidizing catalyst (52) is provided in an exhaust passage. After performing rich control, which controls so that the air / fuel ratio of an air / fuel mixture formed in a combustion chamber (25) is richer than the stoichiometric air / fuel ratio, lean control is performed, whereby the air / fuel ratio of the air / fuel mixture formed in the combustion chamber is either controlled so as to be leaner than the stoichiometric air / fuel ratio by a preset degree or temporarily controlled so as to be leaner than the stoichiometric air / fuel ratio by a preset degree. When lean control is performed after the completion of rich control, provisional lean control is performed, whereby the air / fuel ratio of the air / fuel mixture formed in the combustion chamber is controlled so that, when the air / fuel ratio is controlled lean of the stoichiometric air / fuel ratio in lean control, the degree by which the air / fuel ratio of the air / fuel mixture formed in the combustion chamber is leaner than stoichiometric air / fuel ratio becomes less than the degree preset in accordance with the catalyst temperature.

A method for modifying a transparent electrode film contained in a transparent electrode film-attached substrate having a substrate and the transparent electrode film formed on the substrate includes annealing the transparent electrode film by applying flash light having an optical pulse duration time of 0.1 msec to 10 msec to the transparent electrode film using a flash lamp, thereby heating thetransparent electrode film.

An exhaust gas control apparatus includes a first catalyst, a filter, and an electronic control unit. The electronic control unit is configured to alternately execute lean control and rich control multiple times. The lean control is control for, over a period longer than a period from when a target air-fuel ratio is set to a predetermined lean air-fuel ratio until an air-fuel ratio of exhaust gasflowing out from the first catalyst becomes greater than the stoichiometric air-fuel ratio, setting the target air-fuel ratio to the predetermined lean air-fuel ratio. The rich control is control for,over a period longer than a period from when the target air-fuel ratio is set to a predetermined rich air-fuel ratio until the air-fuel ratio of exhaust gas flowing out from the first catalyst becomes smaller than the stoichiometric air-fuel ratio, setting the target air-fuel ratio to the predetermined rich air-fuel ratio.
