An optical reflection film in which haze is reduced and cracking hardly occurs. An optical reflection film is provided. An optical reflection film includes at least one unit formed by laminating a low refractive index layer and a high refractive index layer on a substrate. The high refractive index layer contains zirconium oxide particles, and the low refractive index layer contains silicon oxide particles and two or more cationic polymers.

Optical reflection film

An optical reflection film may include an optical interference film formed by alternately laminating a high refractive index layer and a low refractive index layer with a refractive index difference therebetween on a substrate. Among the high refractive index layers and the low refractive index layers constituting the optical interference film, if a layer disposed closest to the substrate is defined as a lowermost layer, a layer farthest from the substrate is defined as an uppermost layer, and each of layers disposed between the lowermost layer and the uppermost layer is defined as an intermediate layer, the average elastic modulus of the intermediate layers measured by a nano-indentation method is higher than the elastic modulus of the uppermost layer by 2 GPa or more, and the film thickness of the uppermost layer is 1.2 to 7 times the average film thickness of the intermediate layers.

Optical reflection film and optical reflector

An optical reflective film including refractive index layers containing a water-soluble resin is provided, wherein the film has a small color tone variation and less occurrence of cracks even after a prolonged use. An optical reflective film, including: a substrate; and a dielectric multilayer film formed by alternately laminating a low refractive index layer and a high refractive index layer, disposed on one surface of the substrate, wherein at least one layer of the low refractive index layer and the high refractive index layer is a water-dispersible cationic urethane resin-containing layer, containing: a water-soluble resin; a refractive index adjusting agent; a water-dispersible cationic urethane resin; and a cationic polymer having a tertiary amino group or a cation (salt) thereof or a quaternary ammonium group.

Transmission control device for automatic transmissions that changes rotation output speed of turbocharged engines. An intake-state detecting unit detects an engine intake state and at least one of intake air amount, intake pressure, and engine air-fuel ratio. An intake-state determining unit determines whether a target intake state is satisfied based on detecting unit detection results and sets the target intake state based on target torque and engine operating range. A transmission-pattern selecting unit has a first transmission pattern for setting a transmission gear ratio based on an operational state and a second transmission pattern for setting the transmission gear ratio such that an engine rotation speed is higher than that in the first transmission pattern. The first or second transmission pattern choice is based on whether or not the target intake state is satisfied or not. A transmission controller controls a transmission mechanism based on the transmission pattern selection.

A diagnostic control device for a hybrid vehicle is provided for shortening the time required for a failure diagnosis of an evaporation purge system. After introducing the inlet-pipe's negative pressure into the evaporation purge system, the evaporation control unitdiagnoses failure states concerning the evaporation purge systemsuch as a leak by detecting changes in inner tank pressure over a prescribed time. In order to shorten such failure diagnosis control time, a motor generatoris driven to assist the engine when introducing the inlet-pipe's negative pressure into the evaporation purge systemWith such assist-driving, it becomes possible to reduce engine load, therefore, the throttle valveof the enginecan be controlled to be on the closed side, making it possible to create sufficient inlet-pipe's negative pressure. Through this, the pressure in the evaporation purge systemcan be decreased quickly, which shortens the time for failure diagnosis in the evaporation purge system

It is determined whether an engine for a flexible fuel vehicle is in a start enabling state based on alcohol concentration of fuel supplied to the engine. When it is determined that the engine is in the start enabling state, a heater for vaporizing fuel is energized. Current flowing in the heater is compared with a reference current representing completion of warmup of the engine. When the current becomes smaller than the reference current, the heater is de-energized, and the fuel is injected to start the engine.

Method of controlling an engine for a flexible fuel vehicle

A flexible fuel vehicle has an engine with a fuel injector for injecting mixed fuel of gasoline and alcohol into the engine. The operation of a starter motor of the engine is inhibited for a set time period before injecting the mixed fuel from the fuel injector and the mixed fuel is circulated flowing from the fuel pump to the fuel tank for the set time period so as to sufficiently and homogeneously mix the gasoline and alcohol in the mixed fuel.
